King Of Prussia, NJ is widely recognized as one of the region's premier commercial and residential hubs, known for destinations like the King of Prussia Mall, extensive shopping and dining options, and its convenient location near several major Pennsylvania highways. Alongside its rapid growth and busy atmosphere, many homeowners in King Of Prussia still experience basement moisture problems and foundation concerns caused by aging construction, seasonal weather conditions, and changing soil and drainage patterns.

At Jamison Basement Waterproofing, we provide reliable waterproofing solutions tailored to the needs of King Of Prussia homeowners. Older foundations, mature landscaping, and varying drainage conditions can all contribute to basement leaks, water intrusion, and excess humidity beneath the home. Our team works to identify the source of the problem and install dependable long-term systems designed to keep your basement dry, healthy, and structurally protected.

The King Of Prussia area experiences humid summers, cold winters, and regular rain and snowfall throughout the year. Freeze-thaw cycles and aging drainage systems can place added stress on foundation walls and basement floors over time, increasing the risk of cracks, mold growth, musty odors, and structural deterioration if moisture issues are not properly addressed.

Our experienced waterproofing specialists offer a complete range of basement and foundation services, including interior drainage systems, sump pump installation, exterior waterproofing, crack repair, crawl space moisture control, and foundation stabilization solutions. Every project is customized to the specific condition and layout of your home to provide dependable, long-lasting protection.

For more than 35 years, Jamison Basement Waterproofing has proudly helped homeowners throughout Pennsylvania maintain safer, drier homes. As a family-owned and operated company, we remain committed to delivering quality workmanship, honest recommendations, and personalized waterproofing solutions backed by decades of experience and trusted customer service.

Crawlspaces Repair Services

A big portion of the air you breathe comes from the basement and crawlspaces. You want to take as much care of your crawlspaces as much as you do for your basements. Jamison Basement provides complete solutions for keeping your crawlspaces dry including dehumidifier installation and crawlspace encapsulation.

Sump Pump Installation

Water will naturally flow to your basement, the lowest part of the house. To remove accumulated water, you will have to use sump pumps. We only install the most highly reputable sump pump brands. Aside from that, we make sure that you have reliable battery back-up so your sump pump will work even when there are power outages. This is particularly useful during storms when basement flooding is more likely.

Radon Gas Testing and Mitigation

Radon is a naturally occurring but dangerous gas that can enter your home through cracks in your foundation walls. It's an invisible and odorless gas, so you won't know if there's radon without the use of specialized tools. Jamison Basement provides radon testing and mitigation services in King Of Prussia.

We also installed a new Grate-Sump pump which will pump any ground water away from the crawlspace all while keeping the crawlspace Dry of ground water seepage...

The challenge we faced was having to work in the crawl space of a brand-new addition. This was very difficult because the clients had spent a lot of money and everything was brand new, so we could not get a piece of dirt or dust on anything.

Senior Project Manager Steve Custus, with over 16 years of experience, went out to meet with the builders who built the new addition.

The best solution for this problem was to install the GrateDrain drainage system, a GrateSump sump pump, and a moisture vapor barrier on the crawl space walls.

Foreman Kareem B. and his team performed the installation. The process began with preparation, including protecting all the client’s items and controlling dust. The GrateSump pump pit was the first thing the crew installed, then they moved on to jackhammer the floor around the perimeter of the crawl space. They cleaned the concrete dust from the area and laid a layer of crushed stone down. The GrateDrain drainage system was pitched downhill, connecting to the sump pump pit. After that, fresh cement was poured and leveled around the perimeter to provide a smooth finish.

The solution we provided was a full encapsulation & drainage system in the crawlspace. In the Basement we installed a full moisture vapor barrier with Grate-Drain Drainage system that will channel all of the ground water seepage to the new Grate-Sump all while keeping the basement floor Dry.

Mike R Berwyn (Builder)

September 04, 2013 | Berwyn, PA

Jamison Basement Waterproofing installed a full perimeter Grate -Drain (Closed) DrInage System to protect all 142 linear feet of their basement from water intrusion. Also installed was the patented freeze stop system which will prevent their basement from flooding should the exterior pipes ever freeze up in the winter time , The homeowners were also concerned about what would happen should a hurricane or other extreme weather event happen in the area again. To ensure that the basement would never flood even during power outages, Jamison Basement Waterproofing installed 2 sump pump which has a battery Inverter for 24-hr protection . Dave the Project manager also recommended several Inspection ports so that the homeowners could move their high volume dehumidifier from location to location without ever having to empty the water and to make inspection of their system in the future very easy for future annual service. Crew Foremen : Steven Custus and crew went over and behind to wow this client.
