Here’s Why So Many New Buildings Look Like Shit—And Will Look Worse in 10 Years
The article addresses the common observation that many new buildings, from condos to stadiums, appear shabbily constructed, with their exteriors deteriorating prematurely. This phenomenon is attributed primarily to the widespread use of a specific type of siding material and installation techniques that are relatively new and inadequately tested. The author, having grown up with a father in the siding business, notes that even a non-expert eye can spot issues like warped siding panels in recently built structures.
Chris Knutson, a second-generation siding installer in the Twin Cities, confirms these observations. He states that the problem lies not only in the quality of installation but also in the material itself. Knutson explains that many of the materials and techniques used are novel, lacking long-term wear testing, and that many installers are unfamiliar with proper application. He specifically criticizes slot panel siding, commonly found in "5-over-1" style construction projects, which is typically made from engineered wood, steel, or fiber cement. Despite its popularity for apartment remodels, Knutson regards it as an inferior and untested product, predicting widespread failure within 10 to 20 years, necessitating complete exterior replacements.
A key vulnerability of slot panel siding is its susceptibility to water damage. Knutson contrasts it with traditional lap siding, which features multiple overlapping panels designed to shed water effectively. In contrast, panel siding offers only a single point for water drainage, making it prone to failure, a problem Knutson reports seeing evidence of already. This issue is not confined to residential buildings; large-scale structures are also affected.
An example cited is the U.S. Bank Stadium in Minneapolis, where the black metallic zinc siding began to detach just six years after construction, leading to a substantial $21 million repair cost. Knutson suggests that professionals, including his father and himself, anticipated this failure due to the inherent problems with the material and its installation. Another contributing factor to these construction failures is a shortage of skilled labor. Knutson highlights the difficulty in finding experienced workers, implying that some construction companies may be hiring less experienced individuals who lack the necessary precision and care for the job. He emphasizes that the inherent design of certain siding products demands perfect installation to prevent failure, a standard that is rarely achievable in practice.
