Professional Basement Waterproofing and Crawl Space Repair in Conshohocken, PA

Conshohocken, PA is widely recognized for its vibrant restaurant scene, thriving business district, and convenient access to Philadelphia, making it one of the region's most desirable places to live and work. From historic homes to newer residential properties, many structures throughout Conshohocken still encounter basement moisture problems and foundation concerns as a result of aging materials, shifting ground conditions, and year-round weather exposure.

At Jamison Basement Waterproofing, we provide customized waterproofing and foundation repair services designed to help Conshohocken homeowners protect their properties from water damage and structural issues. Basement seepage, damp walls, elevated humidity levels, and settling foundations are often caused by poor drainage, hydrostatic pressure, or deteriorating foundation surfaces. Our team performs thorough inspections to determine the source of the problem and installs dependable waterproofing systems built to deliver long-term results.

Homes in Conshohocken are exposed to humid summer conditions, freezing winter temperatures, and regular rain and snowfall throughout the year. These seasonal weather patterns can cause the soil around the foundation to expand and contract repeatedly, creating pressure against basement walls and floors. If moisture intrusion is left untreated, it can eventually result in cracked foundations, mold growth, musty odors, wood rot, and structural deterioration that may become more costly over time.

Our experienced waterproofing professionals offer comprehensive services including interior drainage systems, sump pump installation, crawl space encapsulation, exterior waterproofing, structural stabilization, moisture control systems, and foundation crack repair. Every solution is tailored to the specific condition and layout of the home to help ensure reliable, lasting protection.

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

The challenge we faced was that it was a stone foundation, and nothing is easy when trying to make an opening in an 18-inch-thick stone foundation wall. Each stone had to be removed one by one by a stone mason.

To address this, we installed a new egress window that is up to code for a secondary exit out of the basement. Now Chris can finish the basement and does not have to worry about the safety of his tenants if they ever need to exit out of the basement.

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 having to move the washer, dryer, and a few other items.

To address this, we installed a Santa-Fe Advance 2 system and painted the walls.

August 06, 2016 | Wyndmoor, PA

The challenge we faced was that we had to gut the entire basement because the water problem had been going on for a while, and mold was certainly growing behind the finished material, so we had to get down to the root of the problem.

To address this, Project Manager Steve provided a full GrateDrain drainage system with a full vapor barrier, along with complete encapsulation of the dirt crawl space. We even extended a downspout underground free of charge to get as much water away from the foundation as possible. The Walkers said they chose us over our competitors because we were the only company that was not pushy during the sales call. Now that the groundwater issues have been taken care of, they can refinish the space and add a new playroom for their children.

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.

I scheduled a follow-up site visit so someone can come out and explain the proposed basement waterproofing work after I return from out of town.
Caroline F.

I scheduled a site visit so my crawl space can be evaluated and to get an estimate for installing a dehumidifier. The company will send a confirmation.
Mary beth M.

I previously had Jamison waterproof my basement and experienced water entering overnight; I scheduled a free inspection so they can diagnose the source and recommend next steps.
