What Do You Put Down Before Siding on a House in Smithtown?
Before we install any new siding, we prepare your Smithtown home with a breathable, water-resistant house wrap. This protective layer keeps moisture out while allowing trapped humidity to escape, protecting your home’s structure from within.
Skipping this step can lead to:
✔ Wall damage caused by hidden moisture
✔ Growth of mold or mildew
✔ Premature siding wear
✔ Insulation breakdown over time
We follow all manufacturer specifications to make sure the job is done right from the inside out.
Is a House Wrap Necessary Before Siding Installation in Smithtown?
Absolutely—house wrap is an essential part of every siding installation in Smithtown. Thermo-Seal includes this step to protect your home from wind, rain, and moisture intrusion.
Without house wrap, moisture can sneak behind your siding and cause serious long-term problems. With it, you get a more durable, insulated, and weather-resistant home.
