A Building Manager in Brooklyn had an issue where their basement would flood with water when it rained. Looking for a solution, the Building Manager contacted Quality 1st Basements. System Design Specialist, Jeff Nero, examined the basement and recommended the SuperSump waterproof the basement. The SuperSump is designed to help keep the basement dry and healthy for extended periods of time, even in times of heavy water intrusion. Project Manager, Melvin Cardoza, and his team installed the SuperSump and now the Building Manager's basement no longer floods with water.

This homeowner got water in his basement after heavy rain storms. He contacted Quality 1st Basement Systems to waterproof his basement. The installation team installed the WaterGuard basement waterproofing system to stop his basement from flooding. Because of the frequent basement flooding, the sheetrock was soft and rotted. Quality 1st Basement Systems replaced the damaged sheet rock with EverLast basement wall panels which are insulated and made with completely inorganic materials so they will never grow mold or be damaged by water.

Basement Waterproofing & Crawl Space Repair

If you have experienced basement flooding or leaking cracks we fix the issue. We seal and repair any wall cracks and install a basement drain. The interior drainage system collects any water sneaking into your home and drains it to an efficient sump pump. From there the water is pumped out and away from your home before you ever notice. 

The same applies with leaking or wet crawl spaces. Along with the drainage systems in the basement or crawl space we also install energy-efficient dehumidifiers to control the relative humidity. By controlling the space mold and rot are prevented.

Job Stories From Kings County, NY
Wet Basement with Damaged Walls in Brookyln, NY

A Brooklyn homeowner noticed their basement would flood after heavy rain. The walls were damaged from the water seeping through and he knew that they would have to be replaced. He contacted Quality 1st Basement Systems when he stumbled upon their advertisement on the internet. Not only does Quality 1st offer basement waterproofing but Basement Finishing as well. This was the perfect opportunity to waterproof his basement but replace the walls for a more updated finish look. He decided to call Quality 1st Basement Systems after reading through the various positive reviews on the website.

System Design Specialist, Laszlo Lenkey, inspected the affected area thoroughly and recommended a TripleSafe Sump Pump System and Water Guard French Drain be installed. The Sump Pump is the world’s most reliable pumping system as it can discharge 11,500 gallons in total with the highest level on. In addition, Laszlo suggested the EverLast Basement Wall System to be installed as it restores any of the existing walls damaged from water or high humidity. The EverLast Wall is a textured Mold-Proof, washable and vinyl finish providing the basement with an updated, clean and finished look. Quality 1st Basement Systems not only provided this homeowner with a waterproof solution to keep their basement dry but was able to provide them with a whole new look for their basement, leaving them happy and greatly satisfied.  

Brooklyn Basement gets Waterproofed

A Brooklyn homeowner had moisture in their basement and found Quality 1st Basements in their internet search. System Design Specialist, Jeff Nero went to inspect the home and noticed the moisture the homeowners had reported. WaterGuard was installed in the basement by Foreman, Victor Leon and his crew. WaterGuard is installed below the floor slab out of the "mud zone" so the drain does not clog. The WaterGuard system collects water that seeps in through basement walls and drains it into the sump pump. The SuperSump Premier Pump System is an economical solution to keep the basement dry, pumping 2,200 gallons of water per hour out of an 8-foot head out of the basement. Next, a SaniDry Dehumidifier was installed to filter the basement air so it is clean and healthy. To keep the basement waterproof and warm, ThermalDry Radiant Barrier was installed. Not only does ThermalDry Radiant keep the basement warm, it also serves as a vapor barrier. An easy way to upgrade basement walls is to install CleanSpace Wall System to hold back water vapor passing through the foundation walls, and directing it to the sump pump. This basement is fully waterproofed and ready to be used by the homeowners!
