Crawl Space Repair Solutions in & Encapsulation in Philadelphia & nearby PA & NJ areas

Homes built with crawl space type foundations in the years after WW2, were quite popular in the U.S. This system allowed homes to be built faster and more affordably than those with full basements. Additionally, they provided the needed access to plumbing, wires, and ducts. The problem is that builders did not take into account the issues that we know now. For example, the way the type of crawl space ventilation preferred then worked ended up creating more problems than it solved. Crawl space vents were a source of numerous problems including structural decay, mold, pests, and significant energy penalties.

Jamison Basement Waterproofing offers reliable solutions for all the common crawl space problems. Protect your home, your family’s health and lower your energy bills with our Crawl Shield Encapsulation System and structural repair services.

Common Crawl Space Problems

Groundwater Intrusion

In a perfect world, crawl spaces would have built-in drainage systems, or they would be at least properly graded to prevent water from pooling in the space.

Often, however, that is not the case, and groundwater puddles in the crawl space which is always bad news. 

Jamison Basement Waterproofing offers the most advanced drainage solutions for your crawl space.

High Humidity

Why are crawl spaces so prone to moisture? Well, it has to do with the very way they are built. The dirt floor in crawl spaces simply allows water to evaporate in the space, and the crawl space vents originally thought to allow moisture to dry, aggravate the problem by allowing humid outside air in.

Our advanced crawl space encapsulation system is designed to effectively address all sources of moisture.

Mold, Odors & Structural Decay

Every environment where Relative Humidity is at or above 60% is a breeding ground for mold and dry rot. Crawl spaces are notorious for having serious moisture problems that cannot be solved with vents, crawl space vent fans, or a thin plastic sheet on the floor to serve as a vapor barrier.

Jamison Basement Waterproofing crawl space solutions are based on the most recent building science recommendations.
