Professional Basement Waterproofing and Crawl Space Repair in East Lansdowne, PA

East Lansdowne, PA is recognized for its historic homes, diverse community, and convenient location near Philadelphia's cultural and recreational attractions. While the borough's early 20th-century architecture adds charm and character, many homes throughout East Lansdowne can still face basement moisture problems and foundation concerns as older construction materials and changing soil conditions continue to age over time.

At Jamison Basement Waterproofing, we provide trusted waterproofing and structural repair services tailored to the specific needs of East Lansdowne homeowners. Basement leaks, damp walls, musty odors, excess humidity, and settling foundations are often caused by poor drainage around the home, hydrostatic pressure beneath the foundation, or weakened structural components below grade. Our team performs detailed inspections to identify the root of the issue and installs reliable systems designed to provide long-term protection against water intrusion and structural damage.

Homes in East Lansdowne are exposed to humid summers, freezing winter temperatures, and regular rain and snowfall throughout the year. These seasonal weather changes can cause the surrounding soil to shift repeatedly, placing pressure on basement walls and foundation floors. If moisture issues are ignored, they can eventually contribute to mold growth, wood rot, cracked foundation walls, unpleasant odors, and worsening structural deterioration inside the home.

Our experienced waterproofing professionals offer a complete range of services, including sump pump installation, interior basement drainage systems, crawl space encapsulation, foundation crack repair, exterior waterproofing, moisture control systems, and structural stabilization solutions. Every waterproofing strategy is customized to fit the condition, layout, and long-term needs of the property to ensure dependable results.

For more than 35 years, Jamison Basement Waterproofing has helped homeowners across the region maintain dry, safe, and healthier homes. As a family-owned and operated company, we are committed to providing honest recommendations, experienced craftsmanship, and reliable customer care backed by decades of basement waterproofing and foundation repair expertise.

November 30, -0001 | Haverford, PA

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.

August 01, 2016 | Wynnewood, PA

The challenges we faced were that it was a very large basement, requiring around 240 feet of drainage system with a full vapor barrier and 3 sump pumps. Another challenge was that the floor in the lower basement was very hard to jackhammer in order to install the system.

To address this, we installed a full drainage system with a complete vapor barrier and 3 sump pumps.

We provided a grate sump with drainage system along on pe wall we also cut the finish walls 4ft high and ran 4ft vapor barrier up the walls as well .

August 08, 2016 | Drexel Hill, PA

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 .

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.

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.

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.

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.

January 11, 2017 | Wynnewood, PA

Project manager Steve recommended a closed sub floor Drainage system called GrateDrain to redirect water from under the basement floor at the floor wall joint to the new GrateSump , the GrateSump can remove up to 2400 gallons of water per hr from the Basement. Steve also recommended a high volume dehumidifier to eliminate the high levels of moisture in the basement and to eliminate the homeowners fear of mold. Crew Foremen Dwight C Project Manager Steve C
