Clean crawl spaces also improve home comfort & energy efficiency

A crawl space that’s damp and dirty is more than just an eyesore. It causes health, safety, comfort and home resale problems. This happens because a damp, dirty crawl space creates a favorable environment for mold, mildew, wood rot, insects and animal pests. Who wants these difficulties right below a home’s living space?

The good news is that a nasty crawl space can be transformed into a clean, dry, attractive and energy efficient space using the CrawlSeal® encapsulation system installed by Ohio Basement Systems.

How the CrawlSeal® liner works

CrawlSeal® liner

Compatible products. When the crawl space floor is damp or wet, drainage matting and CrawlDrain™ perimeter drain lines can be installed before laying down the CrawlSeal® vapor & moisture barrier.

One of the key ingredients in our encapsulation system is the CrawlSeal® vapor barrier, a super-durable, 20mil plastic sheet material designed to permanently prevent moisture, outside air and pests from getting into your crawl space. Your crawl space technician will install CrawlSeal® poly over the foundation walls and floor to create a continuous air and moisture barrier.

Depending on conditions in your crawl space, other crawl space products will also be necessary – like crawl space vent covers, insulation and drainage matting. Don’t worry; all these products have been designed to work together, transforming a “problem” crawl space into a clean, energy-efficient space that is no longer scary or hazardous to enter.

The CrawlSeal® crawl space liner and drainage matting are installed exclusively by Ohio Basement Systems in Cleveland, Akron, Strongsville and throughout Ohio. Contact us today to request your free cost estimate.

Frequently Asked Questions About the OBS CrawlSeal® System

The OBS CrawlSeal® system is the best in the business. What do you need to know about installing the CrawlSeal® system?

What Is the CrawlSeal® Encapsulation System? 

There are many methods of crawl space encapsulation, and CrawlSeal® is one of the best methods of encapsulating your crawl space. It’s super-durable, compatible with other crawl space materials, and available for use on the floor and walls. That’s what makes it the right choice for Ohio homeowners.

Do I Need Crawl Space Encapsulation? 

You might feel like you don’t really “need” crawl space encapsulation. However, if you choose to forgo crawl space encapsulation, you’ll end up with plenty of problems. Chief among them is crawl space moisture, which can itself create a variety of concerns. With CrawlSeal®, you don’t have to worry about those moisture-related concerns.

Why Is a 20mil Vapor Barrier the Right Option? 

You may see other companies using 12mil vapor barriers, with some companies cutting corners to the extent where they choose 10mil or even 6mil barriers. However, these barriers will tear more easily and are more likely to allow moisture through. CrawlSeal® is a 20mil vapor barrier, which will provide the maximum amount of safety and security for your crawl space.

Can I Purchase CrawlSeal On My Own? 

Because you need a professional and accurate installation, Ohio Basement Systems doesn’t sell it directly to consumers. It’s best if you allow a certified installer to do it. If you’re looking for a better way to keep moisture out of your crawl space, you can contact Ohio Basement Systems to request a free quote for CrawlSeal® installation in your home.
