What Do You Put Down Before Siding on a House in Greenwich?
Before siding is installed, our Greenwich team applies a high-performance house wrap that keeps water out and lets moisture escape from within the walls. This prevents long-term structural issues and supports energy efficiency.
Without this barrier, homes can suffer from:
✔ Mold or mildew growth
✔ Damage to insulation and framing
✔ Siding that wears out too soon
✔ Poor energy performance
We never skip this vital step.
Is a House Wrap Necessary Before Siding Installation in Greenwich?
Yes—house wrap is included in every Thermo-Seal siding installation in Greenwich. It creates a breathable seal that keeps your home protected through humid summers and icy winters.
This extra layer ensures your siding performs to its full potential while extending its lifespan.

What Our Clients Are Saying About Us
Thermo-seal Windows provides exceptional customer service alongside high-quality products. Recently, I had the majority of my home's windows replaced by Aaron's team, and their performance was nothing short of impressive.

Aaron and his team were amazing, from start to finish! They worked with us every step of the way and Aaron was always just a call or text away to answer any questions we had. The windows are perfect and we love them. We highly recommend working with Aaron and his team. They are professional, courteous and their work is top notch!
