This homeowner had a leaky window and barely any sunlight coming into the basement. Not only was the basement dark but it was cold and wet  from the water coming through. Quality 1st Basement Systems replaced the old window and installed a Egress Rockwell with a Sunhouse Shallow Dome lid. By replacing the window, water will no longer be able to come through, keeping the basement dry. Quality 1st was able to allow more natural lighting into the basement and provide the homeowner with an emergency egress to allow a safer exit for anyone living in the basement.

After hearing about Quality 1st through a magazine, this Warren, NJ homeowner called for a free estimate. The foundation of his home had cracked and was beginning to bow out. System Design Specialist, Kenny T. inspected the foundation and determined that installing Our GeoLock Channel Anchor System would be the best solution. 

On the day of the installation, Victor and his team installed the system to support and stabilize the foundation. First, they dug a small trench in the dirt outside of the foundation. Next, they drilled a hole through the wall to drive the rod into the soil. The rod was then connected to an anchor in the earth and attached to the inside wall plate. Once the wall plate was attached, the soil and sod were replaced and compacted. The last step was to tighten the anchors one last time. 

Once the installation was complete, the foundation was completely stabilized and the homeowner no longer had to worry about their basement walls cracking and bowing anymore.

Our high quality work and exclusive access to over 28 patented products set us apart in the home improvement industry. When working on basements, crawl spaces and foundations we are the safe choice for your home.

Basement Waterproofing & Crawl Space Repair

Basements and crawl spaces consistently have issues with water, mold and rot. To prevent these problems from occurring in the future we install a patented interior drainage system. Water and moisture that enters the basement is captured, controlled and safely removed via the basement drain before you ever notice it. The drainage system also works as part of crawl space encapsulation. 

We Provide:
  • Basement Waterproofing
  • Crawl Space Encapsulation
  • Exclusive, Patented Products
  • Humidity Control
You Receive:
  • Permanently Dry Basement
  • Clean Protected Crawlspace
  • Protection against Mold
  • Improved Home Value

We also fix basement leaks with permanent basement leak repair. With our system in place there is no need to fear basement flooding. We want your basement to be safe for years so our work comes with a transferable lifetime dry-basement warranty. 

Foundation Repair & Concrete Leveling

Whatever the issue we are the trusted foundation repair contractor. Our foundation repair experts will visit your home, identify the issue and recommend the right solution. We provide permanent foundation repairs using non-invasive methods. There is no need to tear up your entire yard to fix the foundation.

We Use:

Crawl space off of den area can be damp. There is a sump pump installed in the floor of the crawl space. I am thinking that we might look into alternatives to keep the crawl space as clean and dry as possible.
