Pennington, NJ is known for its charming small-town atmosphere, highly rated schools, and welcoming residential neighborhoods that attract families and professionals alike. With its blend of historic homes, established properties, and beautifully maintained landscapes, many homeowners in Pennington experience basement moisture problems and foundation concerns caused by aging construction, seasonal weather conditions, and changing soil and drainage patterns over time.

At Jamison Basement Waterproofing, we provide reliable waterproofing solutions specifically tailored to the needs of Pennington 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 issue and install dependable long-term systems that help keep your basement dry, healthy, and structurally protected.

The Pennington area experiences humid summers, cold winters, and regular rain and snowfall throughout the year. Freeze-thaw cycles and aging drainage systems can place additional stress on basement walls and foundation floors, increasing the risk of cracks, mold growth, musty odors, and long-term structural deterioration if moisture problems are not properly addressed.

Our experienced waterproofing professionals 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 reliable, long-lasting protection.

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

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 Pennington.
