How Can Vapor Barriers Help?
The area beneath your home doesn’t exist in a vacuum. Just like your walls and ceilings, unless you take steps to insulate it your floors will let cold air in. Not only that, there is a wide range of home-related problems that can occur due to moisture. Protecting your home means getting professional service, and nobody provides a more cost-effective installation of vapor barriers in Portland than the technicians at Northwest Weatherization.
Protect your home against invasive moisture from the ground up.
Get the right protection for your home.
We use a wide variety of materials to protect your home against moisture. Depending on the positioning of your home and scope of the crawlspace beneath it we may recommend 6, 8, or even 12-millimeter vapor barriers. 12 mil is the strongest available. If you plan on using the area beneath your home for additional storage or other use, this is recommended.

Moisture barriers protect your home against:
- Sewage, moisture, and water buildup underneath your home. The installation of a vapor barrier can keep contaminants out. Flooding can wash in sewage waste if you aren’t protected, and barriers keep it out. It also prevents water from seeping into your foundation and causing deep rooted and costly damage.
- The risk of odor and mold. Mold needs a warm place to grow. Once it’s established it doesn’t take long for it to enter your home. This typically occurs out of sight behind walls and flooring. This can lead to an expensive restoration and health problems. Our barriers prevent growth conditions and mold growth.
- Reduce the chance of bursting pipes. Burst pipes are almost always due to freezing temperatures. Insulating the underside of your home raises the temperature. This helps regulate the sub-floor temperature in every season and protects pipes from freezing in winter.
- Electrical waste and efficiency loss. Moisture buildup makes your home cooler. That means additional heating costs. You also work your furnace harder and cause it to fail that much sooner. Our technicians help eliminate moisture. That saves you money now and later.
Crawlspace encapsulation protects your health.
Your home may be exposed to above-average levels of Radon. This odorless gas can be a major health risk when present. It occurs in certain areas due to the composition of the soil. Crawlspace encapsulation uses our thickest barriers. It seals off all vents and requires careful taping off of any seams. This serves to eliminate the possibility radon will enter your home from below.
