Professional Basement Waterproofing and Crawl Space Repair in Trenton, NJ

Basement Waterproofing Services

Trenton, NJ is recognized for its historic neighborhoods, established residential communities, and mix of classic architecture and modern development. With many homes throughout the area built decades ago, basement water issues and foundation concerns are common challenges for local homeowners—particularly during periods of heavy rainfall, snowmelt, and seasonal temperature changes.

At Jamison Basement Waterproofing, we provide professional waterproofing services designed to help Trenton homeowners protect their homes from water intrusion, moisture buildup, and structural deterioration. Our team understands the unique conditions affecting homes across Central New Jersey and installs long-lasting systems tailored to each property’s needs.

The Trenton area experiences humid summers, cold winters, and frequent precipitation throughout the year. Freeze-thaw cycles, aging drainage systems, and shifting soil conditions can all contribute to basement leaks, foundation cracks, mold growth, and damp living spaces over time. Addressing these issues early can help prevent more extensive damage and costly repairs later on.

Our experienced waterproofing professionals offer a complete range of basement and foundation solutions, including interior drainage systems, sump pump installation, exterior waterproofing, crack repair, crawl space moisture control, and foundation protection services. Every project is customized to create a cleaner, drier, and healthier environment beneath your home.

For more than 35 years, Jamison Basement Waterproofing has served homeowners throughout the region with dependable workmanship and trusted customer service. As a family-owned and operated company, we remain committed to providing honest evaluations, effective waterproofing solutions, and reliable results that homeowners can count on for years to come.

The challenge we faced was removing the finished material to access the wall crack that the homeowner did not know was hidden behind the finished wall.

To address this, we offered our maximum protection package, where we sealed the crack from both the inside and the outside. On the outside, we dug all the way down to the footer and applied a rubber membrane and coating. On the inside, we installed our Techni-Crack repair system to ensure the homeowners would not have a problem from this wall crack again. Now they can begin the process of refinishing the damaged finished material in their basement.

Jamison Project Manager Ken McKnight, who brings over 15 years of experience with the company, conducted the inspection and recommended the installation of Rhino brand carbon fiber straps. This solution was designed to reinforce the compromised foundation wall and prevent any further movement.
After the carbon fiber straps were professionally installed, the structural concerns were effectively addressed. With the added confidence of Jamison’s transferable lifetime warranty, the homeowners were able to put the property back on the market where it sold quickly and without issue.
