What makes a Knapp Construction home built to last
Our Philosophy
Having spent years in water and fire restoration, Patrick Knapp has seen firsthand how homes fail — and why. That experience became the foundation of a building philosophy centered on prevention: using the best materials, methods, and systems from the start, so the problems others are called in to fix simply never happen.
Most home failures trace back to water intrusion. Our Superior Wall foundation system, ZIP System sheathing, and Schluter waterproofing products are all chosen because they create a continuous, reliable barrier from the ground up — eliminating the gaps where moisture enters and damage begins.
We build with 2×6 exterior walls instead of the standard 2×4. That extra 2 inches means significantly more insulation capacity, a stiffer structure, and a home that holds its temperature and integrity far better over time. It's a choice that costs more — and one we'd never skip.
From the ZIP System's weather-resistive barrier warranty to Schluter's lifetime system warranty, we spec products that manufacturers stand behind for decades — because we stand behind every home we build for just as long.
Copper stub-outs at every toilet. Engineered TJI floor and roof systems. AdvanTech subflooring. These aren't marketing points — they're decisions made in the walls, under the floors, and behind the fixtures that you'll never see but will always benefit from.
Superior Walls are precast concrete foundation wall panels engineered for superior strength, insulation, and moisture resistance. Unlike poured concrete, Superior Walls arrive on site precision-manufactured with built-in steel reinforcement, drainage channels, and pre-insulated cavities — dramatically reducing the risk of cracking, leaking, and moisture intrusion that plagues traditional foundations.
ZIP System replaces traditional OSB + housewrap with an integrated structural panel and built-in weather-resistive barrier — sealed with ZIP System tape at every seam. The result is a tighter, drier, more energy-efficient building envelope that outperforms conventional sheathing methods. Huber backs it with an industry-leading warranty.
AdvanTech subflooring by Huber is the industry's most moisture-resistant engineered wood panel — the same manufacturer as ZIP System. It resists swelling, squeaking, and fastener pull-through far better than standard OSB subflooring, and its flat, stiff surface gives your finish floors a superior foundation to perform on.
TJI (Trus Joist I-Joists) by Weyerhaeuser are engineered lumber products used in place of traditional solid-sawn floor and roof framing. They're straighter, lighter, stronger, and dimensionally stable — meaning no warping, twisting, or shrinking that causes squeaky floors and cracked drywall over time. Roof truss systems add the same precision overhead.
Schluter Systems are the gold standard in tile installation and waterproofing — used by professional tile contractors who refuse to cut corners. From KERDI waterproofing membrane in showers to DITRA uncoupling membrane under tile floors, Schluter products eliminate the moisture failures and tile cracking that plague standard installations.
Two choices that most production builders would never make — but that we make on every home. Copper stub-outs at every toilet instead of cheap PEX fittings, and 2×6 exterior wall framing instead of the standard 2×4. Small details with decades of impact.
