Darby, PA is recognized for its deep historical roots, diverse neighborhoods, and convenient location just outside Philadelphia. With many older homes and long-established residential properties throughout the borough, basement moisture issues and foundation problems are common concerns for homeowners dealing with aging construction materials, shifting ground conditions, and years of seasonal weather exposure.

At Jamison Basement Waterproofing, we provide customized waterproofing and foundation repair services designed specifically for homes in Darby. Water seepage, damp basement walls, musty odors, elevated humidity levels, and settling foundations can all result from poor drainage, hydrostatic pressure, or weakened foundation structures. Our team performs detailed inspections to determine the source of the issue before installing reliable waterproofing systems built for long-term performance and protection.

Homes in Darby experience humid summer weather, freezing winter temperatures, and frequent rain and snowfall throughout the year. These changing seasonal conditions can cause the surrounding soil to expand and contract repeatedly, placing stress on basement walls and concrete floors. When moisture intrusion is not properly addressed, it can eventually lead to foundation cracks, mold and mildew growth, wood rot, structural weakening, and unhealthy indoor air conditions.

Our experienced waterproofing professionals provide a full range of services including interior drainage systems, sump pump installation, crawl space encapsulation, exterior waterproofing, structural stabilization, moisture control systems, and foundation crack repair. Every project is customized to fit the unique condition and layout of the home to help ensure dependable, long-lasting results.

For more than 35 years, Jamison Basement Waterproofing has helped homeowners throughout the region maintain dry, stable, and healthier homes. As a family-owned and operated business, we remain committed to delivering honest recommendations, skilled workmanship, and dependable customer service backed by decades of basement waterproofing and structural repair experience.

Jamison Basement is the leading basement waterproofing service provider in Southeastern Pennsylvania. Our systems are designed to be flexible enough to handle all types and sizes of homes. With the kind of weather in Darby and the age of the existing homes, you'll need a reliable basement waterproofing system to keep your basement dry.

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 Darby.

This was a tough job because we had to do all the waterproofing from the exterior. Another challenge we faced was that a concrete slab was in the way, so it had to be removed and put back by us in order to complete the installation. To address this, we installed a below-grade dampproofing solution with tar and membrane on the outside of the foundation wall.

The challenge we faced was that water was coming up through the floor where an old sump pit had been covered over.

To address this, we installed a new Fast Sump with a 1/3 HP pump. We also painted a few areas on the wall where the paint was peeling to give it a clean look, and we did not charge him for the paint touch-up.

Since it was a finished wall, it was not possible to see behind it, which made the leak harder to find. However, once the wall was cut, the leak was identified. To address the issue, we provided one wall of drainage system with a new pump replacement and a backup inverter for 24-hour protection.

We totally encapsulated the entire crawlspace & sealed it off from the home , than we even installed a high efficient dehumidifier for moisture control & coated the basement walls & floor to seal moisture out . Mr. Murphy said this might be the best room in the house now .

J Cousouins

September 28, 2016 | Philadelphia, PA

The challenges we faced were that it was a really nice finished basement, so we had to be extra clean.

After our waterproofing specialist Steve Custus went out to inspect the issues, he recommended replacing the other waterproofing company’s drainage system with our patented GrateDrain drainage system, which can handle large amounts of groundwater efficiently. We also installed a new Grate Sump pump with a built-in pump stand and an airtight sump lid. Now that the groundwater problem has been taken care of, the homeowners have peace of mind.

We provided the new homeowner with a high quality , high efficient basement dehumidifier that can remove up to 90pints of moisture a day from the basement air . The homeowner also like that fact that they didn't have to dump any buckets the until drain the condensation right into the basement Sump pump .

We replaced the clog part of her existing system then applied some outside damp proofing to prevent mud from washing in again.

Lizanne

October 10, 2016 | Drexel hill, PA

The challenges we faced were that we had a totally finished basement with carpet and everything, so our Senior Project Manager Steve first had to find the leak by starting with an outside water test to locate it.

Steve had seen this problem a few times before, so he knew how to approach it. After finding the leak, he recommended removing the lower portion of the wall. We then installed a new drainage system, parged the wall where the mud was washing into the basement, and tested the existing sump pump. Problem solved, and the homeowner was happy that she did not have to replace her entire existing drainage system.

Project Manger Steve Custus went out and met with the investors . He recommended a Grate- Sump basin with a built in pump stand , air-tight sump lid with a floor drain and because of the high water levels he recommended a higher capacity Sump pump with a dual float switch to ensure them they won't have another issue when it comes to the Sump pump.

The challenge we faced was that it was a hard floor to demo.

To address this, we installed a drainage system along with a full vapor barrier on the back wall and a sump pump replacement.

Project Manager Steve Custus went out to meet with the homeowners in they stress the fact that they will be remodeling their basement in saw signs of water seepage and wanted to invest in the best drainage system on the market . So we provided the homeowners with a Grate-Drain system that will collect water below the slab and channel it to the new Grate Sump . We also protected the walls with a moisture & vapor barrier now they can finish their project knowing they have a Waterproofing system in place if they should ever need it
