Reliable moisture barrier solutions for your home

Excess moisture in your home can lead to mold, mildew, and structural damage. At Attic Star, we specialize in moisture barrier installation to protect your home from the damaging effects of moisture buildup. Our team uses high-quality materials and advanced techniques to install moisture barriers that keep your living spaces dry and healthy.

Whether you’re dealing with a damp crawl space, basement, or attic, our moisture barriers are designed to prevent water intrusion and control humidity, helping to improve your home’s energy efficiency and air quality.

Proper installation requires trained experts

Attic Star can expertly install plastic or foil sheeting of moisture / vapor barriers to your crawlspace, basement, building walls, attic or roof to prevent water vapors in your home air from penetrating into insulation and surrounding structure. 

We are able to fully encapsulate any crawl space or exterior wall structures creating a permanent physical barrier between water, top soil and your home’s structure.

Attic Star are experts in moisture barrier / vapor barrier design and installation. We use the highest quality Visqueen and advanced sealing materials (up to 20mm thick). 

The IRC (International Residential Code) recommends builders install a Class-I or -II vapor retarder on the interior side of homes in climate zones such as Seattle and Tacoma.

“In most U.S. climates, vapor barriers, or — more accurately — vapor diffusion retarders, should be part of a moisture control strategy for a home.”
