Tenafly's Basement, Crawl Space & Foundation Contractor

For over 25 years, Quality 1st Basements has been the trusted basement & foundation company of Tenafly. 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.

Repairs for:
  • Wall Cracks
  • Bowing Walls
  • Uneven Floors
  • Settling Foundations
  • Uneven Concrete Slabs       
We Use: 
  • Wall Anchors
  • I-Beam Wall Braces
  • Foundation & Slab Piers
  • Crawl Space Jack Posts
  • PolyLEVEL 

Along with general foundation problems we also fix sunken concrete slabs using PolyLEVEL. PolyLEVEL is an expansive polyurethane foam that fills in the gaps beneath the sunken concrete and lifts it back up to a level position. It also does not erode or wash away. If you are looking for the right foundation repair company, you found it. Let's get started.

Job Stories From Tenafly, NJ
Finished Basements Need Waterproofing Too!

When your basement is fully finished, basement waterproofing is not something you want to be thinking about.  Fortunately, Quality 1st Basement Systems can help waterproof your basement no matter what condition it’s in.  Jayshree P.’s basement was fully finished when water started coming from the boiler room floor and another part of the basement when it rained or there was heavy snow.  They could not find the source on their own so it was time to contact the professionals.

Kenneth Peare, waterproofing specialist, assessed the situation and recommended the installation of a SuperSump sump pump, WaterGuard interior basement waterproofing system, LawnSpace, and IceGuard to make sure water can still be pumped out even with snow and ice conditions.  The SuperSump pumps 2220 gallons per hour at an 8-foot discharge head efficiently and quietly.  It resists clogging and can pump up to ½ solids while performing reliably for many, many years. 

After these products were installed, Jayshree P. contacted Quality 1st Basement Systems when the alarm on his SuperSump went off.  Juan Garcia went out to fix the problem and now the basement is dry all year round.  They no longer have to worry about water leaking into their finished basement and can enjoy the space for years to come.   

Window Well Seepage Solutions for Your Home

Homeowner Sarah N. contacted Quality 1st Basement Systems for an estimate because water was leaking into her basement through a window well.  Waterproofing expert Nick Biris went out to Sarah N.’s Tenafly home and surveyed the damage.  He concluded that a TripleSafe sump pump, SaniDry dehumidifier, and WaterGuard interior basement waterproofing system would keep the basement floor dry.

Additionally, ThermalDry basement floor matting was installed to create a thermal break between the finished floor and the cold basement floor.  To address the window well seepage, Wilver Cardoza and his trained team installed a SunHouse basement window enclosure that would brighten up the basement and effectively keep water from leaking into the basement as well. 

Sarah N. and her family no longer have to worry about leaky basement windows or basement water causing problems during heavy rain.  The TripleSafe has three pumps that will keep up with any amount of water and the SaniDry basement dehumidifier ensures a basement that is free of musty odors.  Contact Quality 1st Basement Systems today for a clean, healthy basement just like this one. 

Basement and Crawl Space Waterproofing in Tenafly, NJ

Basement water is something that nobody wants to deal with, but it is extremely common in homes.  Leaking walls, basement flooding, and moisture are all problems that Amy S. faced in her home’s basement.  Basement waterproofing specialist, Mike Bonfante from Quality 1st Basement Systems met with Amy S. and came up with the perfect solution for her basement water woes. 

He recommended the WaterGuard interior basement waterproofing system that is designed to sit on top of the footing and out of the soil under your basement floor so that it won’t clog.  This system drains water from the edge of your basement walls and directs it straight into a sump pump.  In this case, the TripleSafe sump pump was installed.  This patented sump pump is designed to handle any amount of water that is flooding the basement.  It has three pumps to turn on according to the conditions at the time to keep your basement clean and dry!

Amy S.’s basement was completely waterproofed, but a few months later, she realized it was time to have Quality 1st Basement Systems check out her crawl space as well.  They installed the durable, long-lasting CleanSpace liner, Silver Glo, and TerraBlock crawl space floor insulation to keep her crawl space water free and warm all year round as well.  Thanks for this qualified, experienced team, both basement and crawl space water is no longer a worry for this satisfied family!
