What Is Crawl Space Encapsulation?

Superior Groundcover’s encapsulation services mitigate the risk of structural issues by reducing moisture to a crawl space area. Crawl space encapsulation keeps harmful mold from growing and ensures lower heating and cooling costs. Superior’s services will save you money while extending the life of your structure.

How It Works

There are five steps to our crawl space encapsulation process.

Encapsulation Process

1. Clean the Space & Fix Any Issues

If there is any existing structural or water damage in your crawl space, it will need to be repaired prior to beginning the encapsulation process. Check for and remove any debris, especially anything sharp that could puncture the encapsulation seal.

2. Measure Your Material

An accurate measurement of your surface area (the base and the walls) will determine how much polyethylene plastic is required for the job. Full, effective coverage ensures there is nowhere for moisture to build up underneath the plastic sheeting.

3. Apply the Stone Base

In some cases, the ground of a crawl space may not be flat—if it is full of depressions, a stone base will be spread throughout, providing an even base for the plastic sheeting to properly lie. Our Express Blower® trucks have long, pliable hoses that make installation easy, even in the tight, difficult-to-access crawl space.

4. Seal the Space

By overlapping sheets of the polyethylene plastic, we will meticulously cover the floor and walls of your crawl space—the vents, pipes, and pillars will be wrapped in the crawl space vapor barrier, too. In some cases, sprayable insulation can be applied to help seal any gaping holes or fragmented areas.

5. Regulate Humidity

A key aspect to proper crawl space encapsulation is the regulation of humidity. A dehumidifier will be installed to keep levels from exceeding 50% humidity—no mold here!

Who Needs Crawl Space Encapsulation?

Anyone that owns a building with a crawl space can benefit from Superior’s services, including:

Commercial building owners: Water damage can be incredibly destructive to the structural integrity of a building. Don’t risk having to temporarily close your business to deal with expensive, time-consuming repairs. Crawl space encapsulation is an easy way to ensure your space is safe for your team and customers to use everyday.

Residential homeowners: As a homeowner, you want to keep your space as healthy and safe as possible. Moisture build-up leads to mold growth, but crawl space encapsulation prevents this from occurring. Protect your family and your property investment by preventing water damage.

Property developers: If you’re building a new home, crawl space encapsulation is a must. Not only are you ensuring future residents are safe from potential structural issues, but you can also market your space as completely protected from moisture-related issues.

Cost of Crawl Space Encapsulation

The factors that impact the cost of crawl space encapsulation include:

Condition of existing space: If your current crawl space has existing water damage, additional reparative work may need to be done before the space can be properly sealed. Whether Superior takes on this work or an outside contractor does, it will incur additional fees.

Size of crawl space: The surface area requiring covering will determine how much sheeting is necessary, impacting the cost of the crawl space encapsulation.

DIY vs. Professional Encapsulation

Professional encapsulation ensures there is zero chance of moisture formation.

You may be tempted to try and seal your crawl space on your own, and we implore you: don’t! The long-term potential risks of an improper encapsulation far outweigh the short-term money saved by not hiring a professional. Crawl space encapsulation needs to be done right the first time to avoid extremely expensive structural problems.

When Superior Groundcover is brought in to encapsulate a crawl space, we can ensure that it is fully prepped and effectively sealed, allowing no amount of moisture to penetrate the seal. Don’t risk experiencing structural damages or mold buildup as a result of poorly executed DIY encapsulation.
