Basement Repair Done

Basement Repair & Waterproofing

We offer a sub-floor drainage system for basement waterproofing. It is engineered specifically to solve water-related basement problems without clogging from soils under the floor. We can customize our system to meet the needs of any home, regardless of age or size.

Foundation Repair & Waterproofing

Let it be your residential property or commercial property, it is built on the foundation. Therefore any minor damage in the foundation poses threat to the whole building. We fix any cracks or leaks on your foundation and correct the drainage and water flow problems contributing to water leaks and dampness.

Crawl Space Encapsulation

For sealing the crawl space, we provide a patented crawl space encapsulation system that stops vapors and foul odors rising from the ground fully and creates a layer of protection in between the dirt floor and your living space. It reduces your home's heating bills as well.

Most pleasant estimate that made the most sense , the installation crew was courteous, unfortunately the project manager did not communicate with the crew and they fixed the wrong crack the first time they came out . The return quick and made the adjustment and I was very satisfied.

Jamison Basement Waterproofing installed a new GrateSump sump pump. The GrateSump pump has the capacity to remove up to 2400 gallons of water per hour and an has air tight lid that cover prevents moisture from getting into the crawl space and keeps water out of the crawlspace creating a healthier home environment. We also installed a closed drainage system ( GrateDrain )which will channel ground water from the floor wall joint to the GrateSump.. The homeowners are free to enjoy their new house without worrying about water damage or leaking. Buying a home is stressful enough, and now they can relax knowing that it will stay dry and healthy thanks to Jamison Basement Waterproofing ..

Project Manger George, who has well over 20 years experience, went out to meet with the homeowners to do a full basement inspection. After the meeting the homeowners decided to install the Grate-Drain drainage system to relieve the hydro-static pressure from beneath the basement floor.

We decided to install the very effective sub-floor closed drainage system known as GrateDrain. The GrateDrain System collects the water from around and under the basement floor and channels the water to the sump pump. After the Grate Drain System is installed, the basement floor is restored. Additionally, inspection ports are placed throughout the system for easy inspection. Project Manager : Steve C Crew Foreman: Dwight C

Project Manager Steve Custus inspected the basement and determined that water was coming into the basement through the concrete floor at the floor wall joint. It was also determined that water was entering the basement through the basement entry way doors. Jamison Basement Waterproofing installed a full perimeter GrateDrain drainage system which drains any incoming water to the existing sump pump, keeping it out of the basement. The Grate Drain Sub floor drainage system is the only closed drainage system on the market, promoting a healthy home. Now the homeowners have a lifetime warranty that’s transferable to the next homeowners thanks to Jamison Basement Waterproofing. Project Manager Steven Custus Crew Foreman Dwight Custus

Project Manager Steve C. recommended a doorway entry drain that will drain water from the leaky bilco door area into the GrateDrain drainage system. The Grate Sump will then pump the ground water away from the home. Now the homeowners can refinish the basement without fear of the basement flooding due to ground water seepage.
