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.

Project manager Steve Custus went out to meet with the homeowners and to find out their future plans for the basement, after the basement inspection Steve recommended a closed drainage system ( Grate Drain ) and replacing the homeowners existing Sump pump with a new ( GrateSump ) the GrateSump can remove up to 2400 gph of water from the basement.

Project Manager Steve C educated the homeowner on the importance the downspout in that it’s job is to redirects the water away from your foundation by taking the water that it collects within your gutters and pushing it through the vertical tube that runs alongside the home. Your downspouts are often found at the corners of your home where gutters meet. However, downspouts can be at any point that is low. Steve recommended that step 1 was getting all the rain water away from the foundation.

The challenge we faced was that it was a finished basement, so we had to remove the sheetrock and studding to get to the foundation wall.

To address this, Project Manager Steve went out to meet with the homeowner and explained the whole process from top to bottom. The homeowner was very happy with our solution over the rest. Then our senior foreman, Ken McKnight, went out to install the job, and he and his crew were quick and efficient. They installed our patent Grate Trench to protect the basement from any water coming in at the back door, which connects to our Grate-Drain system that channels the water below the slab to our very efficient Grate Sump. Now the homeowners can get the basement refinished. Problem solved.

The challenges we faced were extending all the downspouts under the front walkway, which involved having to cut through solid concrete pads.

To address this, Project Manager Steve Custus went out to meet with the new homeowners. Steve explained how a basement leaks and that the first step to having a dry basement is getting all the water away from the foundation by extending all the roof gutters to the rear of the yard and ensuring proper grading. Project Manager Steve and his crew completed this project in about 7 hours, and the impact it will have on the basement will be enormous.
