Damp guarantee – is it worthless?

Damp in a home can pose significant problems if not addressed promptly, potentially leading to costly repairs. This comprehensive guide provides strategies for identifying and treating various types of damp, including rising damp, penetrating damp, and condensation. Early detection is crucial, with common signs including wet patches on walls, peeling wallpaper, flaking plaster, musty odors, rotting wood, and the appearance of mold or mildew. One effective method for managing excess moisture, especially from indoor activities like drying clothes, showering, and cooking, is to use a dehumidifier. These devices actively draw moisture from the air, and choosing between refrigerant and desiccant types depends on specific needs. Proper home ventilation is also highlighted as a simple and often cost-effective solution for condensation, the most common form of damp. Installing extractor fans in bathrooms and kitchens, regularly opening windows, drying clothes outdoors, and incorporating window or air vents can significantly reduce humidity levels. Penetrating damp typically results from structural issues such as faulty guttering, roofing problems, or cracks in external walls, allowing water to seep through. Identifying this type of damp involves looking for discolored interior walls, damp patches, mold, blistered plaster, and wet surfaces. Checking and repairing external gutters and downpipes is a primary step. If bricks have become porous, applying an exterior silicone water-repellent fluid or limewash can reseal walls while allowing them to breathe, though professional advice is recommended for older homes. Addressing rot in timber, which can lead to structural damage, is critical. Wet rot thrives on constant moisture and is characterized by black fungus, soft timber, and a musty smell. Dry rot, more aggressive, requires less moisture, can spread to non-timber materials, and presents as white or orange growths, crumbling timber, and a mushroom-like odor. Suspected rot necessitates specialist intervention. For rising damp, the article explains the importance of a damp-proof course (DPC) and damp-proof membrane (DPM), compulsory in new homes since 1875. If these are absent, damaged, or ineffective, treatment options include injecting damp-proof cream into walls or installing a physical damp-proof course. Repairing or replacing a damp-proof membrane involves applying waterproof emulsion for minor issues or full replacement for extensive damp. Additionally, ensuring external ground levels are at least 15cm below the DPC is vital, as built-up soil can bridge the barrier. Tanking, which involves sealing walls or floors with materials like asphalt or membrane, is a more intensive and costly solution for severe damp. The guide also advises caution with ‘free damp surveys,’ recommending multiple quotes and considering an independent damp specialist for an unbiased assessment. It also discusses guarantees for damp-proofing work and consumer rights if work is deemed unnecessary. Common causes of penetrating damp are further detailed, including air gaps around windows and doors, burst gutters and pipes, porous bricks, and issues with cavity walls, such as debris accumulation or defective cavity trays. Rarely, poorly installed cavity wall insulation in areas with severe wind-driven rain can also contribute. Finally, preventative measures include ensuring clothes and linen are fully dry before storage, ventilating storage areas, and using natural remedies like boiling lemons to combat musty odors. In cases of severe storm damage, the article emphasizes contacting emergency services, insurance companies, and specialists, and advises on safety precautions when cleaning up flood-affected areas. #DampProofing #HomeMaintenance #MoistureControl #RisingDamp #PenetratingDamp #Condensation #PropertyCare #HomeImprovements #MoldPrevention

This article aims to help homeowners identify the specific type of damp affecting their property to ensure effective and cost-efficient treatment. The three most prevalent types of damp in residential properties are rising damp, penetrating damp, and condensation, each requiring distinct remedial approaches. Understanding the nature of the damp is crucial before undertaking repairs, as costs can escalate significantly with worsening conditions. While often appearing together, damp and mould are not synonymous; damp refers to accumulated moisture within a building's structure, whereas mould is a fungus that thrives in such moist environments. Damp can exist without mould, and vice versa. Condensation is identified as the most common form of damp, arising when warm, moist air cools and condenses on cooler surfaces like walls and windows. This issue is particularly common in moisture-generating areas such as kitchens and bathrooms and tends to be more prevalent in winter when external temperatures are lower. Factors like central heating cycles (heating and cooling) and insufficient ventilation can exacerbate condensation. Older homes, originally designed for natural ventilation, can experience increased condensation problems due to modern energy-saving modifications like airtight double glazing and the removal of chimneys. Symptoms of condensation include water droplets on windows or walls, the growth of dark mould, especially around windows, and a characteristic musty odor. Untreated condensation can lead to damage to paint, plaster, and window frames. Solutions involve wiping away moisture, improving ventilation through extractor fans, and using dehumidifiers. Rising damp occurs when ground water permeates upward through walls or floors. This process is normally prevented by a damp-proof course (a waterproof horizontal barrier in walls) and a damp-proof membrane (an impervious sheet under floors), which are standard in newer constructions according to building regulations. Older buildings, particularly those built before 1875, may lack these barriers or have degraded ones, making them susceptible. Poor drainage or ground levels higher than the damp-proof course can also contribute to rising damp. Key indicators include damaged skirting boards and plaster, peeling paint and wallpaper with wet patches, a white powdery substance (soluble salts) on walls, tide marks, and lifting floor coverings. Repairing rising damp can be a slow and costly process. Penetrating damp is characterized by water leaking directly through walls, typically expanding horizontally rather than vertically. This type of damp is usually a result of structural issues, such as faulty gutters, roofing problems, or cracks in exterior walls, allowing water ingress during heavy rainfall. Internal leaks from plumbing fixtures can also be a cause. Older buildings with solid walls are more vulnerable to penetrating damp compared to newer homes with cavity walls that offer better protection. Depending on the root cause, penetrating damp can often be addressed more quickly and less expensively than rising damp. Identifying the source of the leak is the first step towards effective treatment. #HomeMaintenance #Damp #Condensation #RisingDamp #PenetratingDamp #Mould #HomeImprovements #PropertyCare #BuildingRegulations

The article addresses a common concern for property investors: the necessity and value of specialized damp surveys after an initial Homebuyers survey identifies dampness. A prospective property buyer, Tom, recounts a Homebuyers survey that detected damp at the rear of a building, specifically in the ground floor WC, suggesting a faulty or non-existent damp proof course (DPC). Despite believing it to be rising damp and not condensation, Tom questions whether a further, more detailed damp specialist survey is truly essential given its comprehensive scope. The proposed damp specialist survey includes a thorough examination of chimney stacks, external elevations (pointing, brickwork, render), external ground levels relative to internal floor levels, and internal rooms. For each internal room, it involves moisture content and relative damp assessments, salt analysis to determine moisture origin, thermal imaging to ascertain damp extent and source points, and checks for pipe leakage. The specialist promises to identify causes, extent, and recommend rectification works. Responses from other experienced individuals challenge the immediate need for such a specialized survey. Neil Patterson, a member since 2011, raises the point of whether the property is being purchased with a mortgage, as lenders might mandate a damp report. Steven Way, a surveyor, criticizes the limitations of HomeBuyers Reports, stating they often provide insufficient detail and lead to requests for additional surveys. He argues that many aspects of the proposed damp specialist survey, such as checking external conditions and using thermal imaging, should ideally be covered in a comprehensive building survey. Steven Way also highlights that WCs are prone to condensation and surface dampness from cleaning. He suggests that some dampness in older properties is inevitable and not always detrimental, especially in ancillary spaces like WCs. He proposes evaluating damp issues based on three criteria: impact on structural integrity and performance, visual appearance, and health risks. If none of these are significantly affected, remedial work might be unnecessary. Chris Clare further supports this perspective, noting that in 20 years of surveying, he rarely encountered genuine rising damp, attributing most cases to issues like high external floor levels, poor rainwater drainage, or objects bridging the damp course. He explains that DPCs prevent water from both rising and draining downwards, meaning external water ingress can be trapped, mimicking rising damp. He also emphasizes that cold, unheated toilets often collect and condense moisture from the rest of the house, which can be mistaken for other forms of damp. Chris recommends moving into the house and ensuring it is adequately heated before commissioning further surveys, as damp specialists are inherently incentivized to recommend works. #DampSurvey #PropertyInvestment #HomebuyersReport #RisingDamp #PropertyMaintenance #LandlordAdvice #BuildingSurvey #Condensation #PropertyInspection

The article evaluates the best dehumidifiers for home use, particularly for addressing damp, mould, and poor air quality, especially during winter months. It highlights the importance of these appliances in improving indoor air quality and preventing health issues associated with fungal spores. Dr. Rebecca Drummond, an associate professor in the Institute of Immunology and Immunotherapy at the University of Birmingham, emphasizes that dehumidifiers help remove moisture, thereby reducing humidity and inhibiting mould growth. The author, Joanne Lewsley, who lives in a home prone to damp, personally tested twenty different models across various room sizes, assessing their performance against claims made by brands. The testing methodology involved evaluating night and laundry functions, measuring noise levels with a decibel meter, and assessing the ease of use of accompanying smart apps. A humidity meter was used to quantify moisture removal and the time taken to achieve desired humidity levels. Air particle meters verified improvements in air quality, and models that failed to meet expectations were excluded. Energy consumption was calculated to determine the cost-per-use, favoring energy-efficient options. The article also provides a comprehensive guide answering common questions about dehumidifiers, including their function, how to use them effectively, their electricity consumption, running costs, and their efficacy in drying clothes.

This article addresses the common question of whether dehumidifiers can effectively dry out damp walls, especially during colder months. It confirms that dehumidifiers can indeed help reduce moisture in damp walls, preventing issues like mold growth and structural damage, thereby maintaining a healthier indoor environment. However, it emphasizes that dehumidifiers primarily treat the symptoms of dampness rather than the root cause. Experts advise that the underlying reason for damp walls, which can range from flood damage and leaking pipes to rising damp and condensation, must be identified and addressed before or in conjunction with using a dehumidifier. Failure to tackle the source will result in the problem persisting. To maximize the effectiveness of a dehumidifier for drying damp walls, proper placement is crucial. The appliance should be positioned close to the damp area, with sufficient space around it for air circulation. It is generally recommended to keep windows closed when operating a dehumidifier to optimize its performance, although internal doors can remain open. The duration required for a dehumidifier to dry damp walls varies depending on factors such as the extent of the dampness, the size of the affected area, and the dehumidifier's capacity. This process can take anywhere from several days to a few weeks, requiring regular monitoring of indoor humidity levels and adjustment of settings to optimize drying. The article highlights the importance of choosing the right dehumidifier for the task. A high-capacity dehumidifier is typically recommended for drying damp walls, as these units are designed to remove large volumes of moisture from the air efficiently. They work by drawing in damp air, passing it over a refrigerated coil to condense the water, and then releasing drier air back into the room. Additionally, selecting a dehumidifier with a built-in humidistat is advised, as this feature allows for precise control of indoor humidity levels, enabling the unit to automatically turn on and off as needed. The article also recommends specific dehumidifier models, such as the MeacoDry Arete Two, Pro Breeze 30L Premium High Capacity Dehumidifier, and Russell Hobbs 20L Dehumidifier, citing their high extraction rates and suitability for tackling significant damp issues. These appliances are presented as powerful tools for maintaining a dry and comfortable home environment during winter. #Dehumidifiers #DampWalls #MoistureControl #HomeMaintenance #WinterPreparation #AirQuality #HomeAppliances #CondensationPrevention

The author of this post, Andy Manning, details persistent damp problems in his 1888-built terraced property, despite previous refurbishment efforts including re-pointing external walls and re-plastering internal ones after drying. He expresses concern that damp specialists are recommending expensive, potentially unnecessary work without guaranteeing a long-term solution. Manning describes three specific areas of concern: damp under a bay window, a damp patch on a rear window corner extending downwards, and damp patches and crumbling plaster in the kitchen, particularly on a thick chimney breast and an external rendered wall. He questions the effectiveness of injected damp proof courses (DPCs) and whether the Virgin Media installation contributed to the bay window damp. Manning seeks advice from the community on whether to consult an RICS member for a building defect damp survey, and if such a surveyor would be liable if their recommendations fail to rectify the issue. He is wary of spending thousands of pounds without a guaranteed fix. The comments section provides diverse perspectives and suggestions from other landlords and property experts. One commenter shares success with positive input ventilation (PIV) systems from companies like Envirovent or Nuaire, highlighting their money-back guarantee or cost-effectiveness. Another advises checking external water goods, pointing, and potential issues like cavity wall rubble or rusted wall ties, suggesting that injected DPCs are a temporary fix and recommending a local builder's initial assessment. A third commenter expresses skepticism about injected chemical DPCs, citing their unreliability and high cost, especially when coupled with plaster removal. This commenter advises differentiating between rising damp (which occurs at floor level) and damp caused by leaks or condensation, questioning the Virgin box as a primary cause and suggesting checking for leaks around the bay window frame or roof. Another simple piece of advice points to black mould as a likely indicator of condensation. Subsequent commenters recommend getting multiple opinions from good builders and other damp specialists before committing to expensive solutions, noting that personal experience with penetrating damp in solid walls led to internal sealing and insulated plasterboard. One landlord recounts a costly experience with tanking and an RICS surveyor eventually recommending a French drain and removal of textured external coating for lime rendering to allow the property to breathe. The discussion also touches upon the historical context of Victorian properties with solid walls and the importance of proper ventilation, suggesting that modern interventions like cement pointing and injected DPCs can counteract the original design principles, leading to further issues. The author, Andy, provides updates on his checks, including functional guttering, and reiterates concerns about external render and possibly installing an air brick in the chimney stack. A final expert advises on diagnosing damp based on its location and type, advocating for thorough homework before spending money, and recommending dryhomes.net for impartial advice. #DampProblems #PropertyMaintenance #LandlordAdvice #BuildingDefects #DampProofCourse #PropertyRefurbishment #RICS #VictorianProperty #HomeRepair

This article provides an in-depth guide to understanding the costs associated with repairing various types of damp issues in a home, offering insights into typical damp treatment and damp proofing expenses. It emphasizes the importance of accurate diagnosis and encourages homeowners to be informed to avoid unnecessary costs. The content is based on data compiled in collaboration with the Royal Institution of Chartered Surveyors (RICS), leveraging their Building Cost Information Service (BCIS) database, which includes labor, materials, preliminary work, contractor overheads, profit, and VAT, all benchmarked against national averages and current wage agreements. The information is current as of November 2023. The guide breaks down potential damp problems into several categories, detailing the recommended solutions and estimated costs for different house types (terraced, semi-detached, detached) or specific areas (one wall, whole house, by square meter, or room size). For instance, if an existing damp-proof course (DPC) is below ground level, solutions include excavating soil only or excavating and laying a new gravel path, concrete paving slabs, or a 10cm-thick concrete path, with costs varying significantly based on the scope of work. When walls are damp at a low level due to a damaged or non-existent DPC, solutions involve injecting silicone damp-proofing or inserting a new damp-proof course, which entails cutting out brickwork, inserting bitumen-coated hessian, and making good the brickwork. Cavity wall damp penetration issues can be resolved by clearing blocked cavities, a process that can be done from the outside by removing and replacing bricks. For damp penetrating walls at different heights, around windows and doors, or at ceiling height, inserting a cavity tray or a new damp-proof barrier/course is suggested. The article specifies options like polypropylene cavity trays and, for stepped trays, a combination of polypropylene and lead, differentiating costs based on whether scaffolding is required for high-level work. If exterior surfaces are damaged, leading to damp penetration, applying waterproof paint to brickwork, concrete, or rendered surfaces is presented as a solution, with costs depending on the area to be covered and height. Internal wall dampness often requires 'tanking'—sealing walls with damp-proofing material like asphalt or bitumen-coated polyethylene membrane. This process involves removing old plaster, clearing brickwork joints, applying sealing coats, rendering the walls, and reinstating skirting boards. Similarly, damp floors are treated by 'tanking' with bitumen-coated polyethylene membrane or mastic asphalt, necessitating the removal of flooring, screed, and skirting before reinstallation. For kitchen or bathroom damp, installing an extractor fan in an external wall is a practical solution, covering the cost of forming a hole through the cavity wall or window glass. The article also includes a jargon buster for common damp treatment terms, such as DPC, DPM, silicone damp-proof barrier, cavity tray, and tanking, explaining their functions. Crucially, the article advises against paying for unnecessary damp treatment by emphasizing that not all damp issues require expensive professional intervention. Simple measures like improving ventilation, not drying clothes indoors, clearing gutters, or fixing loose tiles can resolve common problems like condensation damp and some types of penetrating damp. It notes that rising damp, while potentially expensive to fix, is one of the least common types. Homeowners are encouraged to monitor damp problems and try inexpensive solutions first. If professional help is deemed necessary, the article recommends obtaining multiple quotes and considering an independent damp specialist's advice to ensure the proposed treatment is genuinely required and cost-effective.

Humidifiers are often considered high-maintenance appliances due to common issues with noise, over-humidification, and the constant need for cleaning to prevent health hazards. While evaporative models are typically loud and require frequent wick replacements, ultrasonic humidifiers, though quieter, can lead to excessive humidity if not carefully monitored. Moreover, all humidifiers demand regular cleaning to prevent the growth of mold and bacteria, which can become a health concern. Previous recommendations for "best humidifiers" often amounted to selecting the "least worst options available" due to these inherent challenges. An earlier model, the ultrasonic Levoit LV600HH, was recognized for its powerful and consistent humidification, as well as its durability, even if it occasionally led to excessively high humidity levels in rooms. However, the introduction of the Levoit LV600S in 2020 marked a significant advancement. This new version integrated smart-home capabilities and several thoughtful design enhancements, addressing many of the traditional drawbacks associated with humidifiers. The Levoit LV600S distinguishes itself through its smart features, which, while offering the convenience of voice and app control, primarily contribute to its ability to self-regulate humidity levels. Unlike many ultrasonic models that require constant user intervention, the LV600S's onboard computer actively monitors and adjusts humidity, preventing over-humidification. This intelligent design allows the device to maintain a consistent humidity level, such as 55%, for extended periods—a notable achievement for an ultrasonic humidifier. Beyond its smart functionalities, the LV600S features a user-friendly design that simplifies maintenance. Its top-filling water tank can sit flat in a sink, making refilling easy and mess-free. The absence of a screw top and the wide opening facilitate access for cleaning. Despite these improvements, regular cleaning remains essential. Humidifiers, by their nature, involve standing water, which can become a breeding ground for microorganisms like mold and bacteria if not properly maintained. Users are advised to disassemble, rinse, and air-dry their humidifiers at least once a week, and to address mineral deposits like limescale with appropriate cleaning methods. The LV600S's design makes this necessary cleaning process less burdensome. Its smooth edges, large opening, and accessible water basin minimize hard-to-reach areas, though some scrubbing is still required. To further reduce mineral deposits and microbial growth, using distilled or demineralized water and an antimicrobial cleaning cartridge is recommended. It is important to note that, due to concerns about the aerosolization of certain chemicals by ultrasonic humidifiers, bacteriostatic treatments containing ethyl alcohol or quaternary ammonium compounds are no longer advised for the LV600S or similar models. #HumidifierReview #SmartHome #HomeAppliances #ProductTesting #HomeMaintenance #AirQuality #LevoitLV600S #UltrasonicHumidifier #CleaningTips

Waterproofing a basement is a strategic home improvement that adds valuable living space and protects the structural integrity of a house. For two-story homes, a basement can represent 33% of the available space, while in one-story homes, it can account for 50%. Finishing a waterproofed basement is a more cost-effective way to expand liveable space compared to building an addition. However, the cost of waterproofing varies significantly based on several factors, with average costs ranging from $2,200 to $7,200, and up to $5 to $10 per square foot. The primary determinant of cost is the intended use of the basement, whether it is for preventing flooding, water ingress, or being converted into an extra room. The initial step in determining waterproofing costs involves defining the basement's purpose. Due to numerous variables, a one-size-fits-all cost estimate is not feasible. Engaging experts is recommended to assess specific needs and provide accurate quotes, as the cheapest option may not be suitable for every home. The main area of concern for basement leaks is often the cove joint, where the footing, wall, and floor connect. A recommended solution involves installing a subfloor drainage channel positioned beside the footer, draining into a redundant sump pump system equipped with a battery-powered backup. Additionally, a high-capacity dehumidifier is crucial for managing water vapor and humidity, completing the waterproofing system. From an investment perspective, waterproofing a basement offers a substantial return. Estimates suggest a 30% to 50% return on investment (ROI), depending on the problem's scope and repairs. For example, an $8,000 waterproofing repair could increase a home's value by $12,000, resulting in a $4,000 profit. Beyond financial gains, a waterproofed basement prevents water and water vapor from damaging organic materials within the house, such as flooring systems, sill plates, wood framing, and insulation, which can soften, rot, and become susceptible to mold over time. This protection ensures a healthy, mold-free environment. Several variables influence the overall cost of basement waterproofing. The size of the basement is a key factor, as drainage channel installation is typically priced per linear foot. Obstacles like oil tanks, HVAC equipment, bathrooms, gas or oil lines, existing walls, and permanent finishings also add to the complexity and cost of the waterproofing system. The homeowner's intended use of the basement also dictates the level of protection required. Basements used as living spaces or for storing valuables necessitate a fully redundant sump pump system to guard against power outages, mechanical failures, or excessive water volumes. A high-capacity commercial dehumidification system is also essential to maintain comfort and protect belongings from moisture. The entry points of water significantly affect the waterproofing method and cost. Water can seep through window wells, basement windows below grade, cracks in walls, pipe penetrations in poured concrete walls, and faulty cove joints. Each entry point requires a specific solution. For instance, water entering through the cove joint or floor cracks demands a perimeter channel deep beside the footer. Leaking window wells require solutions to drain water higher at the well, while leaking wall cracks can often be addressed with a sealing solution. For higher wall leakage, a vapor barrier extending to grade or the top of the joists might be necessary for protection and aesthetic purposes. The volume of water entering the basement determines the pump's horsepower and the number of pumps and wells needed, further influencing the total cost of the waterproofing project. #BasementWaterproofing #HomeImprovement #CostEstimate #SumpPumpSystem #WaterDamagePrevention #PropertyValue #MoistureControl #HomeMaintenance #ExpertAdvice
