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!

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.

We are having water issues in a the back area of our walkout basement
Vicinity of Tewkesbury Pl NW in Washington
Concerned about water that is entering the basement by the back corner. We have had some puddles of water appear in the basement a few weeks ago during rain/snow along a wall that leads into the crawlspace and also noticed moisture along the lower corner of one of the exterior walls and the nearby floor. We were hoping to have someone come out and take a look and see what our options are for remediation.
Vicinity of M St. NW in Washington
Looking to receive an estimate for exterior waterproofing of the front wall of our condo building, and potentially a new drainage system for our downspouts if that's something your team handles.
Vicinity of in Washington
Our sump pump works fantastic, but the discharge is running onto a neighbors' property and forming sheets of ice on their driveway and the sidewalk. We need options for controlling the runoff.
Vicinity of in Washington
We purchased a 100 year old house last year. The basement has an entire perimeter water proofing system, but we've recently been having water issues. A new lateral drain was put in, along an interior wall. However, the water is not my main concert. There are many cracks in the plaster walls and I noticed a few new ones, along w a door jam crack. I would like to make sure there are no foundation issues.
Vicinity of Allison St NW in Washington
We currently have two above ground basement windows appx 30x20 and we'd like to expand them down to 30x50+. So same width, just taller. The are under a cement front porch on a DC row home so it's relatively dry buy you cant stand upright. It's probably 10" from the bottom of the current windows to the ground so this would include digging maybe 30+ inches of soil. Thanks, Kody
Vicinity of D St in Washington
My exterior drainage system is not working. It was installed by previous home owners and it does not drain appropriately, leaving my front and back yard full of standing water whenever it rains.
Vicinity of Fort Totten Drive NE in Washington
