What Do You Put Down Before Siding on a House in Westport?
Before any siding is installed, your Westport home is wrapped in a high-quality house wrap. This breathable moisture barrier allows vapor to escape while preventing water intrusion—protecting your framing, insulation, and interior walls.
Skipping this step can lead to:
✔ Mold and mildew growth
✔ Energy inefficiency
✔ Faster siding deterioration
✔ Structural damage over time
Thermo-Seal ensures this essential layer is properly installed every time.
Is a House Wrap Necessary Before Siding Installation in Westport?
Yes—house wrap is included in every siding installation project in Westport. It acts as a second shield against the elements, especially important in a coastal community like Westport where humidity and storms are common.
This extra layer helps your siding perform better and last longer.
