Professional Basement Waterproofing and Crawl Space Repair in Gwynedd, PA

Gwynedd, PA is recognized for its beautiful residential neighborhoods, mature landscapes, and well-maintained homes. While the community offers a quiet and desirable setting for homeowners, even the most well-built properties can develop basement and foundation issues over time. Water intrusion, foundation movement, and moisture-related damage often occur gradually, making early detection and professional repairs essential for protecting the value and condition of a home.

At Jamison Basement Waterproofing, we provide customized waterproofing and structural repair solutions for homeowners throughout Gwynedd. Whether you're dealing with a damp basement, recurring water seepage, foundation cracks, musty odors, or excessive humidity, our team has the experience to identify the underlying cause and recommend the right solution. We take a thorough, detail-oriented approach to every project to ensure lasting results rather than temporary fixes.

Many homes in Gwynedd area feature mature trees, established landscaping, and expansive lots that can influence drainage patterns around the foundation. When water is not directed away from the home properly, it can collect around basement walls and gradually create pressure against the foundation. Over time, this may lead to cracking, water infiltration, settling, and other structural concerns. Left unresolved, excess moisture can also contribute to mold growth, wood deterioration, and poor indoor air quality.

Our team offers a complete range of basement waterproofing and foundation repair services designed to address these challenges. From interior drainage systems and sump pump installations to crawl space encapsulation, foundation crack repair, exterior waterproofing, moisture control solutions, and structural stabilization services, we tailor every repair plan to the specific needs of the property. Our goal is to provide long-term protection that helps homeowners avoid future problems.

For more than 35 years, Jamison Basement Waterproofing has been a trusted name for waterproofing and foundation repair throughout the region. As a family-owned and operated company, we are committed to delivering honest guidance, quality craftsmanship, and dependable service on every project. We take pride in helping Gwynedd homeowners preserve the safety, comfort, and long-term value of their homes with proven waterproofing solutions and expert foundation care.

The tight basement with a stone foundation had very high humidity. To address this issue, we implemented a full drainage system, sump pump, Santa-Fe dehumidifier, and vapor barrier.




August 31, 2016 | Maple-glen, PA

It was a unique situation because we went to meet the buyer’s realtor at the home, and the homeowners were there as well. Although they said it does not get water, signs all around the basement showed water seepage. After we removed the finished walls, we found that the whole bottom floor plate was rotted out.

To address this, we provided a full drainage system with a sump pump and outside drainage.

On job 623 in Sumter we HEPA-vacuumed demo dust before rebuild handoff. The unique on-site tell was Broad Street staging plus a pin grid that pulled standing water and logged pins. Equipment ran within a 3–7 day meter window with overnight humidity checks—never a multi-week campaign. Photo documentation stayed with the owner; carpenter choice stayed theirs.

Project Manager Steve went out to meet with the property owner and noticed right away that they had a few different problems going on . One was high humidity plus and open Sump pit with standing water that was humidifying the air plus it was signs of water seepage at the back door area so right away he recommended grate channel at the back door and a Grate Sump which is a air-tight Sump basin . Plus we treated the Basement walls with a mold removal paint than coated them with a mold resistant paint . We also installed a partial drainage system with Vapor Barrier to channel ground water to the Grate Sump .

The challenges we faced were the structural repair work and the small crawl space to work within.

To address this, Steve proposed a full perimeter GrateDrain drainage system that offers a lifetime warranty and is transferable to the next homeowners, which was especially important as she was planning to put her house on the market soon. An airtight Grate Sump pump was installed to replace their open sump pit hole, along with a crawl space encapsulation system and structural repair to turn the crawl space into dry, usable space. By doing so, Mrs. Opalisky turned 2000 square feet into dry usable space, therefore increasing the value of her home.

Steve was the project Manager on this one so he went out to meet with Frank . Frank pretty much knew what he wanted so him and Steve came up with the solution of installing Vapor Barrier that will drain down into franks existing systems turning his system into a closed Waterproofing system .

We Proposal a closed Drainage system a long all outside walls with a Grate Sump with a entryway drain to capture water coming into the basement from a leaky belico door . Once our project manager showed the client how efficient our drainage system works it was a no brainer that they do business with us . Now the Homeowners have a Dry Basement !

December 20, 2016 | Lansdale, PA

Because the basement was finished and had a tile floor, we had to be very careful so that damage would be minimal.

To address this, Project Manager Steve went out and met with Kim. Steve recommended a closed drainage system that would capture water at the floor-wall joint and channel it to the existing sump pump. The Grate-Drain drainage system offers a lifetime warranty that is also transferable to the next homeowners. Now Kim can put her house on the market without fear of losing value because of a wet basement. Problem solved.

The challenges we faced were that installing a drainage system in a really tight crawl space is always difficult.

To address this, Project Manager Steve went out to meet with the homeowners at their home in Ambler, PA, and after hearing them out, he knew exactly what would fix their problem.

So, he proposed a full closed drainage system (Grate-Drain) with inspection ports. This system will drain the water into the homeowners’ existing sump pump, which will then pump it out of the crawl space and far away from the home. We were able to solve their problem and save them some money by using their existing sump pump, which had been recently installed.

Steve Custus went out to inspect the property and recommended a full perimeter (Closed ) Drainage system with a new Sump pump with battery back up to keep the basement dry all the Time ! We even prep the basement for its new radon system that will be tied into our Grate Drain Drainage system for maximum effectiveness . Since Jamison Basement Waterproofing offers a life-time warranty the homeowner now has peace in mind. The Foremen Dwight Custus & crew Waterproofed this entire basement in just two days . The homeowners was very impressed with how efficient and neat the installation crew was .
