This Brooklyn basement had water seeping in where the walls met the floors. Quailty 1st Basement Team Systems installed WaterGuard, a SuperSump sump pump, and Everlast wall paneling. The WaterGuard drainage channel will lead any incoming water to the SuperSump sump pump, which will then safely deposit the water outside of the basement. Everlast wall paneling restored the lower half of this basement wall, giving it a fresh new facelift. Everlast not only looks great, it is mold resistent and has a waterproof PVC coating that will keep it dry and moisture free. Now this Brooklyn basement will stay dry and clean!

Job Stories From Brooklyn, NY
Foundation Settlement Repair in Brooklyn, NY

A homeowner in Brooklyn, New York was experiencing stair-step cracking in the exterior of their home. This is a symptom of foundation settlement and should be repaired right away. Foundation settlement happens because of the constant shrinking and expansion of the soil around the home. During periods of droughts, the soil will dry and shrink. During periods of heavy rainfall, the soil gets saturated and expands in size. If gone unrepaired, foundation settlement can be detrimental to the property's home value. 

The homeowner contacted Quality 1st Basement Systems and our System Design Specialist, Steve Ventriglio, was able to provide an inspection of the home and help them find a solution to this issue. Upon his inspection, Steve noticed how the foundation was settling and he suggested they use a pier system to stabilize the home.

Our foreman arrived at the job site and began to prepare for the installation of the Helical Pier System. First, the foreman removes the soil where the piers will be installed. the first pier section is screwed into the ground using specialized hydraulic equipment. Then, a steel foundation bracket is connected to the helical piers and attached to the foundation's footing. The weight of the home is transferred through the helical piers and onto the sturdy soil. Lifting the home back to its original position will be attempted with this solution. When the soil around the area is replaced, the entire system is hidden from view.

The Helical Pier System will bring the home back to its original position, and requires minimal disturbance from the installation. These piers are a quicker installation, rather than a total foundation replacement, which is disruptive and not effective. With the Helical Pier System, the foundation settlement is solved once and for all. 

When the job was complete, the homeowner was pleased with the outcome. they were happy with the professionalism they saw on the job, and they did not have to worry about foundation settlement issues any longer.

Continual flooding issues no success in waterproofing.
Project Location: Brooklyn, NY
Hello, my husband and I need some basement work done after Hurricane Ida caused us to have to gut the basement. It is now fully unfinished. Our top priorities are to seal up the ceiling with plastic and green Sheetrock (the current ceiling is potentially asbestos), installing vent fans, sealing up a crawl space, and insulating some pipes. Other items we would like estimates for so we can consider them are installing flooring, finishing the walls, cleaning up some efflorescence on the foundation walls, and repairing the metal cellar hatch that has corroded. We are eager to do the priority items asap-please let me know the earliest you can come out. Thanks.

For the first time in 15 years, we had 3" of flooding in our basement during Hurricane Ida that I believe came in through back, front and airshaft doors. I'd like to explore options like sump pumps, french drains and possibly a check valve. Thanks!
