Collingswood, NJ is appreciated for its walkable streets, mature trees, welcoming neighborhoods, and strong community atmosphere that gives the area its unique character. While the borough offers convenient suburban living and a rich local culture, many homes throughout the area can still experience basement water intrusion and foundation problems over time due to aging construction materials, shifting soil conditions, and changing seasonal weather.

At Jamison Basement Waterproofing, we provide customized basement waterproofing and structural repair solutions designed to meet the needs of Collingswood homeowners. Water seepage, damp basement walls, excessive humidity, and foundation settlement issues are often linked to poor exterior drainage, hydrostatic pressure, or weakened foundation surfaces. Our team performs detailed evaluations to determine the source of the issue and installs dependable waterproofing systems designed for lasting protection.

Homes in Collingswood are exposed to humid summers, cold winter temperatures, and frequent rain and snowfall throughout the year. These seasonal weather changes can cause the ground surrounding the foundation to repeatedly expand and contract, placing pressure on basement walls and floors. If moisture issues are left untreated, they can eventually lead to foundation cracks, mold and mildew growth, musty odors, wood rot, and structural deterioration within the home.

Our experienced waterproofing specialists offer a full range of services including sump pump installation, interior drainage systems, crawl space encapsulation, exterior foundation waterproofing, structural stabilization, moisture control systems, and foundation crack repair. Every project is customized to fit the layout and condition of the property to help ensure reliable, long-term results.

For more than 35 years, Jamison Basement Waterproofing has helped homeowners throughout the region maintain dry, healthy, and structurally sound homes. As a family-owned and operated company, we are committed to providing honest guidance, quality workmanship, and dependable customer service backed by decades of basement waterproofing and foundation repair experience.

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 Collingswood.
