When drywall goes up, all of the home’s critical systems disappear from view. Electrical wiring, plumbing lines, HVAC ducts, gas lines, and framing are no longer visible once the walls are closed.

​

Years later, renovations, repairs, or system upgrades often mean guessing what’s inside the walls or opening them up just to find out. This leads to unnecessary damage, added costs, delays, and uncertainty for both builders and homeowners.
