Crawl Space Repair in Greater Philadelphia Area

If so, you should consider taking action. Did you know that over 40% of the air that you breathe on the first floor of the home comes from the basement or crawl space? Because of this crawl space waterproofing and encapsulation is essential to your family's health.

A crawl space is essentially a small basement. In homes with crawlspaces, the living area is so close to the crawl space that moisture and unsafe air infiltrate the home, causing potential health hazards.

Crawl Space Problems and Their Solutions

At Jamison Basement Waterproofing, we help our customers in Southeastern Pennsylvania by getting to the root of the problem.

• Crawl Space Drainage System - If there are issues with standing water, we begin by installing a drainage system installed prior to the encapsulation process. We then run this drainage system into our GrateSump, liner and install a sump pump to remove the water from the crawl space.

• DimpleShield Drainage Matting - A dimpled plastic material used on high footings or concrete floor to assist with crawl space drainage issues.

• Crawl Space Vent Covers - Most crawl spaces have been vented due to antiquated building codes. We now know that venting a crawl space creates big problems and it's necessary to seal any vents or areas where outside air can get in. We have patented crawl space vent covers to repair this issue.

• CrawlShield™ Encapsulation System - To complete the process of sealing the crawl space, we install a patented crawl space encapsulation system to completely eliminate vapors and odors rising from the ground; creating a layer of protection between the dirt floor and your living space which also helps in lowering your home's heating bills while making the living space more comfortable.

• Crawl Space Dehumidification System - After the area is sealed, the moisture level will need to be controlled and brought down to a relative humidity below 50%, using our high-efficiency dehumidification systems.
