Basement Waterproofing & Crawlspace Encapsulation

Crawl Space Services in Philadelphia and Wilmington

Do you have a wet or musty-smelling crawl space?

Have you ever thought about the air you breathe in your home? It might surprise you that more than 40% of the air on the first floor comes from the basement or crawl space! That’s why it’s really important to make sure your crawl space is waterproofed and properly sealed. At Jamison Basement Waterproofing, we have provided elite-level crawl space services for customers in the Philadelphia metro area since 1989. We can help you, too!

A crawl space is like a smaller basement; if it’s not taken care of, the moisture and unhealthy air from there can seep into your living area. This can create health risks for you and your family. Keeping your crawl space dry and safe is essential for everyone’s well-being. When you need our help, give us a call for more information or to receive a free estimate. You can also reach out to our Jamison crawl space experts online.

Common Crawl Space Problems We Address in Pennsylvania, Delaware, & NJ

Groundwater Intrusion
Groundwater Intrusion

In a perfect world, crawl spaces would have built-in drainage systems or be properly graded to prevent water pooling. Unfortunately, this isn't always the case, leading to groundwater issues. Jamison Basement Waterproofing provides advanced drainage solutions for your crawl space.

High Humidity
High Humidity

Crawl spaces are particularly prone to moisture due to their construction. The dirt floor in these spaces allows water to evaporate into the area, while the crawl space vents, which were initially intended to help moisture dissipate, actually worsen the issue by letting in humid outdoor air.

Mold, Odors & Structural Decay
Mold, Odors & Structural Decay

Relative Humidity levels at 60% or above create ideal conditions for mold and dry rot. Crawl spaces often face severe moisture issues that traditional solutions like vents and vapor barriers can't fix. Jamison Basement Waterproofing offers crawl space solutions based on the latest recommendations.

Crawl Space Repair Diagram
  • Crawl Space Drainage System: For standing water issues, we first install a drainage system before the encapsulation process. This system directs water into our GrateSump™ liner, where a sump pump removes it from the crawl space.
  • DimpleShield Drainage Matting: A dimpled plastic material used on high footings or concrete floors to assist with crawl space drainage issues.
  • Crawl Space Vent Covers: Many crawl spaces were built with vents due to outdated codes, but we now understand that this can cause significant issues. Sealing vents and outside air access is crucial, and we offer patented crawl space vent covers to address this problem.
  • CrawlShield™ Encapsulation System: To seal the crawl space, we use a patented encapsulation system that eliminates ground vapors and odors. This creates a protective barrier between the dirt floor and your living area, enhancing comfort and reducing heating costs.
  • Crawl Space Dehumidification System: Once the area has been sealed, it’s essential to manage the moisture levels effectively. To achieve this, we will utilize our advanced dehumidification systems to maintain relative humidity below 50%. This proactive approach will provide a controlled environment and prevent potential issues related to excess moisture.

Crawl Space Repair & Encapsulation

Homes with crawl space foundations gained popularity in the U.S. after World War II due to their faster and more affordable construction compared to full basements. They offered easy access to plumbing and electrical systems. However, builders overlooked potential issues, particularly with ventilation, which led to problems such as structural decay, mold growth, pest infestations, and significant energy loss.

Jamison Basement Waterproofing provides dependable solutions for common crawl space issues. Safeguard your home and health while reducing your energy costs with our Crawl Shield Encapsulation System and structural repair services.
