What Do You Put Down Before Siding on a House in Long Island?
Before any new siding is installed, we ensure your Long Island home is protected with a breathable, water-resistant house wrap. This layer stops water from getting in while allowing any interior moisture to escape.
Skipping this vital step can lead to:
✔ Internal wall damage from moisture buildup
✔ Mold and mildew problems
✔ Shorter siding lifespan
✔ Reduced energy efficiency
Thermo-Seal follows every manufacturer guideline to ensure long-lasting protection from the inside out.
Is a House Wrap Necessary Before Siding Installation in Long Island?
Yes—every Thermo-Seal siding installation in Long Island includes house wrap. It’s a non-negotiable step that adds a second layer of defense against the region’s wind, rain, and humidity.
Without house wrap, moisture can become trapped and cause hidden damage. With it, your home stays protected, your siding lasts longer, and you save money in the long run.
