We recently completed this basement waterproofing project in the District to rid the homeowner of their water issues once and for all. After removing the old existing sump pump and pit, we installed a nice, bright CleanSpace vapor barrier, our WaterGuard perimeter system, and a new UltraSump. This will insure that they have a healthy, dry basement for years to come!

Zephranie from Washington DC called NV Waterproofing after finding us on-line, and set up an appointment for a free on-site estimate. She was noticing that her floors over her basement were sagging in certain areas of her home, which had her quote concerned. 

We sent out one of our top system design specialists, Michael, to see what was causing the floors to sag and provide Zephranie with a quote for the repairs.

A Settling Foundation in a Row Home in Washington DC

Ravi, from Washington DC, found NV Waterproofing while doing an internet search. He was worried that his foundation was settling because he was noticing that there were cracks in the walls of his home and as well as several doors that were sticking. Ravi gave us a call and set up an appointment for a free on-site estimate. 

We sent out one of our top system design specialists, Michael, to analyze the situation at Ravi's home. Michael gave him a quote to install our Push Pier System. Our installtion team wound up installing 5 Push Piers, which not only stabilized Ravi's foundation, but also lifted it back to its original position.

Musty Odor Coming From a Crawl Space in Washington DC

David, from Washington DC, was fed up with the constant musty smell that lingered in his row home, even after running a dehumidifier. He searched on the internet, found NV Waterproofing, and gave us a call to set up a free on-site estimate in hopes that we could solve his problem.

We sent out one of our top design specialists to assess David's crawl space, which is where the musty smell was originating from. He gave David all of his options to seal up his crawl space, which would, in turn, alleviate all the moisture and mold that was causing the musty smell. 

David had our installation team encapsulate his crawl space with our patented CleanSpace vapor barrier which will prevent water from entering the crawl space. They also installed our drainage matting system under the CleanSpace to keep and moisture and water vapors away from the vapor barrier. Lastly, they installed our SilverGlo rigid foam insulation against the crawl space walls, just above the CleanSpace, to stop any air leaks. David's problems cleared up instantly and now he has more space for storage, a win-win situation.

Hello, we have a failing retaining wall that abuts our neighbors' property. It's made of concrete and is maybe 3-4 ft high on average. It's leaning over a fair amount and we were wondering if you could give us a quote sometime early in the new year on stabilizing the situation. Thank you.
