This homeowner was experiencing some serious problems in their crawl space. Not only were their floors sagging, the crawl space was also accumulating water! Luckily, our System Design Specialist, Jeff, was able to come up with the perfect solution for their problems. Our  Team installed SmartJacks to stabilize the sagging beams, leveling the floor on the first level of the home. We also installed a CleanSpace encapsulation to prevent water and moisture from seeping through the foundation into the crawl space area. The homeowners crawl space is now another dry and healthy space in their home.

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:

We Use:

Interested in installing Smart Vent Flood Vents
Project Location: Keansburg, NJ
I just purchased a new house which needs quite a bit of work done on the crawl space. It is a small house (about 1200 sq ft). The crawlspace originally had about a foot of water but I was able to remove most of this with sump pump. However, the foundation is eroded and extremely uneven leaving the pump unable to reach many areas and now there is still about a centimeter of water in most areas. I have tried using both a push broom and a dry wet vac to clear the rest of this water but it is difficult to even make a dent. I need the rest of the water pumped out, the space dehumidified, mold cleaned, and new insulation installed. I would also like to know what options I have in terms of renovating the crawl space so that it is easier to clear in the future. Please let me know if this is a job you can help me with. Thank you

After having inspection done we found out that there is evidence of termite damage, some small amounts of mild on sagging insulation, and damp ground with no vapor barrier. The floor in the house has humpsychological and dipping points. Unknown if joists need to be repaired or sintered.

No ventilation or insulation in crawl space. I am interested in an estimate for adding insulation to my crawl space. My floors are freezing as well as the first floor of the house. Also my tile floor is cracking. I'm not sure if it's related.
Project Location: Keansburg, NJ
Our house is about two years old, and within the last year, we finished our basement...some of the interior baseboards grew a little green mold (that I bleached and never came back) and there is a funky smell down there...Ive used Damp Rid and it collects moisture, but doesn't help with the smell. It can't be good for our health let alone our 2 year old daughter. We're noticing a film on certain pieces of furniture too. I want to see my options without having to tear down sheet rock and start over. Please help
