Professional Basement Waterproofing and Crawl Space Repair in Colwyn, PA

Colwyn, PA is recognized for its historic neighborhoods, diverse community, and convenient location near Philadelphia. Many homes throughout the borough have been standing for decades, and while they offer plenty of character, older properties are often more vulnerable to basement moisture problems and foundation deterioration caused by aging materials, drainage issues, and changing ground conditions over time.

At Jamison Basement Waterproofing, we specialize in basement waterproofing and structural repair services tailored to the unique needs of Colwyn homeowners. Water entering through foundation walls, damp basement air, pooling water, and settling foundations are all signs that moisture may be affecting the home below ground level. Our team carefully evaluates each property to locate the source of the issue and recommend long-term waterproofing solutions designed to keep the basement dry and protected.

Throughout the year, homes in Colwyn face humid summers, winter freeze-thaw cycles, and periods of heavy rain and snowfall. These weather conditions can place significant stress on the soil surrounding the foundation, causing expansion and contraction that may eventually impact basement walls and floors. Left untreated, moisture intrusion can contribute to mold growth, musty odors, cracked foundations, weakened structural components, and poor indoor air quality.

Our waterproofing specialists provide a full range of basement and crawl space services, including interior drainage systems, sump pump installation, crawl space encapsulation, exterior waterproofing, crack repair, basement humidity control, and structural stabilization solutions. Every home is different, which is why we customize our repair approach to match the specific needs and condition of the property.

For more than 35 years, Jamison Basement Waterproofing has helped homeowners throughout the area protect their homes from water damage and foundation issues. As a family-owned and operated business, we take pride in delivering reliable workmanship, honest recommendations, and responsive customer service backed by decades of hands-on experience.

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.

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.

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.

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.

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 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 .

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.

After our project manager went out and met with Mr. Daniels he knew that Mr. Daniels just wanted a simple pump replacement so that's what we did . We replaced the very old outdated pump with a new 1/3hp cast iron pump with 3yr warranty. Now Mr Daniels can sleep at night with peace in mind now that he has a reliable pump .

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

March 02, 2017 | Ridley Park, PA

The challenges we faced, besides the fact that she had a finished basement, were that the homeowner also had a second bathroom downstairs that we had to work around in order to install the drainage system properly.

To address this, we installed a full perimeter closed Grate-Drain drainage system with a new Grate Sump and 1/3 HP Fast Sump. We also installed a vapor barrier behind the finished walls and a Grate Trench at the door entryway to prevent any water from entering the basement from the Bilco doorway. This system offers a lifetime warranty. Now Michelle can have peace of mind and refinish her basement later down the line without the fear of it ever flooding again. She also has one year of free annual maintenance, during which we will return annually to clean out the Grate Sump and test the pumps for her. Problem solved.
