Professional Basement Waterproofing and Crawl Space Repair in Gwynedd Valley, PA

Gwynedd Valley, PA is known for its picturesque scenery, historic character, and beautifully maintained residential properties. With mature trees, expansive landscapes, and a strong appreciation for outdoor living, the area offers a distinctive blend of natural beauty and suburban comfort. While these qualities make Gwynedd Valley an exceptional place to live, they can also create challenges when it comes to managing groundwater and protecting foundations from moisture-related issues.

At Jamison Basement Waterproofing, we help homeowners safeguard their properties from basement water intrusion and foundation deterioration. Problems such as damp basements, persistent moisture, foundation cracking, musty odors, and elevated humidity levels are often signs that water is affecting the structure below the surface. Our team conducts detailed inspections to determine the source of the issue and develops customized repair solutions designed to provide reliable, long-term protection.

Many homes in Gwynedd Valley sit on larger lots with extensive landscaping and mature vegetation. While these features add beauty and privacy, they can also influence drainage patterns around the home. During periods of heavy rainfall or seasonal groundwater fluctuations, excess moisture can accumulate near the foundation and place stress on basement walls and structural components. Over time, this can contribute to water infiltration, foundation settlement, mold growth, wood decay, and other costly problems if not addressed properly.

To help prevent and correct these issues, we offer a complete range of waterproofing and foundation repair services. Our solutions include interior drainage systems, sump pump installation, crawl space encapsulation, basement crack repair, exterior waterproofing, moisture control systems, and structural stabilization services. Every recommendation is tailored to the property's specific conditions, ensuring the most effective solution for long-term performance.

For more than 35 years, Jamison Basement Waterproofing has provided trusted waterproofing and foundation repair services throughout Montgomery County and the surrounding region. As a family-owned and operated company, we take pride in delivering exceptional workmanship, honest advice, and personalized customer 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.




September 02, 2016 | Oreland, PA

The challenge we faced was that it was a rental property that had been empty for a few months, and the basement was also finished, which made the job more difficult.

To address this, we installed a drainage system with two new sump pumps and a Santa-Fe Advance 2.

September 21, 2016 | Fort Washington, PA

When we got there, there was a lot of mud and water on the floor, and half of the basement was finished, which made the job more challenging. Taking this into account, and because the homeowner wanted the problem solved as soon as possible, Steve arranged for a production crew to be out within a few days. We installed a drainage system with a full vapor barrier and a Grate Sump with a battery backup for 24-hour protection. We also extended the downspout 10 feet away from the home and washed the floor down. Now the basement is dry as a bone.

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.

Our project manager went out and noticed the block wall had an horizontal crack and started to have some movement so he proposal carbon fiber straps to reinforce the wall and to prevent if from moving again .

November 10, 2016 | Lansdale, PA

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 .

December 01, 2016 | Lansdale, PA

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 12, 2016 | East Norriton, PA

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 .

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.
