Our customers in Flagtown, NJ were looking to waterproof their basement so they could use it for storage. Currently, the items stored in the basement were getting water damaged and destroyed.  System design specialist JC Gibriano met with the homeowners and together they looked at the issues and the ways to fix it.  JC recommended a new TripleSafe Sump pump for the security of having 3 pumps including a battery backup, as well as a full perimeter WaterGuard drainage system.  The customer also decided to have us put CleanSpace on the walls and ThermalDry flooring on the floors.  Esau and his crew installed everything expertly and the customers are in love with the results!

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.

The drainage system also works as part of crawl space encapsulation. 

We Provide:

  • Egress Windows
You Receive:
  • Permanently Dry Basement

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.

Job Stories From Flagtown, NJ
SmartJacks Stabilize Flagtown, NJ CrawlSpace

Laurie H., a homeowner from Flagtown, NJ, became a valued customer of Quality 1st Basement Systems.  With some concerns about her foundation, she scheduled an appointment to have foundation specialist Ken Peare provide a thorough inspection of her home and answer her questions.   

Then Ken Peare developed a plan to meet the homeowner’s needs and provided a free estimate for the cost to resolve her crawl space foundation problems.  Laurie was happy to move forward with the work and put an end to her worries.

The installation of the SmartJack Support System, which includes corrosion-resistant galvanized steel adjustable support columns that can support over 60,000 lbs., provides immediate and permanent stabilization to a home suffering from a sinking and/or settling.  Holes are excavated for each SmartJack being installed and then filled with stone and covered with a concrete base.  The SmartJacks are then cut to size, placed where deemed necessary according to the plan developed during the inspection and estimate, and tightened into place.   This system can also level sloping and sagging floors. 

Additionally, Laurie wanted to prevent colder air from entering the crawl space.  Installation of CleanSpace Crawl Space Vent Covers can provide a barrier from the outside elements.  A new EverLast Crawl Space Door also creates a weather barrier and, because it is made from inorganic materials, it will never rust or rot.  Both the vent covers and crawl space door install quickly and provide an airtight seal.

Laurie H. had no more worries after the installation and Quality 1st Basement Systems was happy to provide this long-term solution.  The SmartJacks restored stability to the home and the CleanSpace Crawl Space Vent Covers and EverlLast Crawl Space Door were a quick but permanent solution to blocking outside air from getting in through these openings.
