This homeowner in Mahwah had water seepage in her basement. The previous sump pump was not successfully pumping water out of her basement. Quality 1st Basement Systems installed a SuperSump sump pump. SuperSump has a sturdy liner that has holes in it to accept water directly from the ground so that it will not short cycle like other sump pumps.

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

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.

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.

Job Stories From Mahwah, NJ
Basement Waterproofing in Mahwah, NJ

During heavy rains, water came up through the floor in Mary W.’s basement.  To find a reliable basement waterproofing company, she consulted Angie’s List online and contacted Quality 1st Basement Systems for a free estimate.

To stop basement leaks, waterproofing specialist Kenneth Peare recommended a TripleSafe sump pump, WaterGuard interior basement waterproofing system, ZenWall basement wall paneling system, and a SaniDry dehumidifier.  The SaniDry model is a super-efficient basement dehumidifier that keeps your space free of moisture and smelly odors.  Additionally, the ZenWall basement wall paneling system is the simplest way to create a clean, finished look for your basement.  It directs basement wall leakage to the WaterGuard system around the perimeter of your space.

This big job was completed in a short three days by Victor Leon and his trained crew.  Mary W. now no longer has to worry about water entering her basement.  The complete waterproofing system will keep her basement clean and dry for years to come.

TripleSafe Sump Pump Installation

Tom D. had water coming into his basement and was interested in a TripleSafe sump pump to keep his basement dry.  That same week he talked to Quality 1st Basement Systems, waterproofing specialist Kenny Tramutola met with Tom at his Mahwah, NJ home.  Kenny recommended the TripleSafe sump pump, WaterGuard interior basement waterproofing system, TrenchDrain, BrightWall, and SaniDry CX. 

The TripleSafe sump pump would be the perfect waterproofing system for his leaky basement because it provides the ultimate protection.  This system has three pumps to respond to any amount of water that is coming into your basement.  If one pump fails the second will take over, and so on.  This in conjunction with the SaniDry CX dehumidifier is sure to keep Tom D.’s basement free of moisture and water. 

But, a few weeks after the installation, the homeowners noticed small pools of water around their SaniDry.  Quality 1st Basement Systems came out to fix the problem and guarantee that the basement would indeed stay dry.  Now the whole family can enjoy this clean, healthy space that is water free!

Waterproof Your Mahwah, NJ Basement Before Selling

Are you a homeowner who’s looking to sell?  Well, Marcia S. was in this same position and was looking to waterproof her basement before it went on the market.  A healthy, dry basement can increase the value of your home and Marcia knew just who to contact for help.  Waterproofing expert, Joe Robinson from Quality 1st Basement Systems went out to assess the situation and came up with a permanent basement waterproofing solution. 

Joe proposed a SuperSump sump pump with an UltraSump battery backup and the WaterGuard interior basement waterproofing system.  This combination would be most effective because as water enters the WaterGuard system it is then drained to the SuperSump, which will pump it straight out of the basement.  The SuperSump sump pump includes the Zoeller cast-iron sump pump that was chosen as the best and most effective among nearly 50 models.

Quality 1st Basement Systems takes pride in the products we provide.  Before selling your home, definitely look into waterproofing your basement.  Marcia S. added value to her home by ensuring a dry, clean basement for any potential buyers, and you can do the same!
