Professional Basement Waterproofing and Crawl Space Repair in Havertown, NJ

Havertown, NJ has long been one of Delaware County's most sought-after communities, known for its welcoming neighborhoods, excellent schools, and strong hometown character. Many homes throughout the area have been standing for generations, offering charm and craftsmanship that homeowners value. As these properties age, however, issues such as basement moisture, foundation settlement, and water intrusion can become increasingly common and should be addressed before they lead to more significant damage.

At Jamison Basement Waterproofing, we help Havertown homeowners protect their homes with customized waterproofing and foundation repair solutions. Problems such as damp basements, water stains, musty odors, visible wall cracks, and elevated humidity often indicate underlying moisture or structural concerns. Our team performs detailed inspections to determine exactly what is causing the issue and develops a repair plan tailored to the home's specific needs.

Many properties in Havertown feature mature trees, established landscaping, and decades-old drainage systems. Over time, changing drainage patterns, soil movement, and groundwater fluctuations can impact the area around a foundation. When water is not properly directed away from the home, it can create pressure against basement walls and gradually work its way inside. Left untreated, these conditions may contribute to mold growth, deteriorating building materials, foundation movement, and poor indoor air quality.

We provide a complete range of waterproofing and structural repair services designed to keep homes protected year-round. Our solutions include sump pump installation, interior drainage systems, crawl space encapsulation, foundation crack repair, exterior waterproofing applications, moisture control systems, and foundation stabilization services. Every project is customized to address the unique characteristics of the property and deliver dependable, long-term results.

For more than 35 years, Jamison Basement Waterproofing has been helping homeowners throughout the region maintain safe, dry, and structurally sound homes. As a family-owned and operated company, we take pride in providing honest guidance, skilled workmanship, and exceptional customer service. Whether you're dealing with a current basement water problem or looking to prevent future foundation issues, our experienced team is committed to delivering solutions you can trust.

The challenge we faced was having to remove the finished material to access the basement foundation walls.

Jamison Basement Waterproofing solved the water and dampness issues by installing a closed GrateDrain subfloor drainage system with a GrateSump System to ensure the basement would stay dry at all times.

Jamison also installed a moisture vapor barrier behind the finished walls to protect against basement wall leaks. Now the basement can be refinished without fear of mold growth.

Certified Crawlspace design specialist Steven Custus went out to do a full inspection this crawlspace. And from his findings he came up with the solution of to removed the debris and sprayed a Mold treatment to prep for the Crawlspace encapsulation. But first To direct water out of the crawl space, Jamison installed a new GrateSump pump. If water enters the crawl space, it flows beneath the CleanSpace liner, across drainage matting into the drainage system to the sump pump. The SuperSump then pumps the water out of the space through a discharge line 15ft away from the house. We also removed the rotted wood supports and installed steel piers for proper support. Than the durable 16 mil thick liner made of many layers of polyester cord reinforcement. Mechanically fastened on the walls and florof the crawl space . The CrawlSheild provides a barrier for any water that may enter the Crawlspace space. One of the greatest top benefits of CrawlSheild is the antimicrobial additive manufactured into the liner. This odorless and safe additive prevents mold growth on the inside of the liner. This crawl space is no dry useable for many years to come . Thanks to the Crawlspace professionals at Jamison Basement Waterproofing. Crew Foreman: Dwight Custus Project Manager Steve Custus
