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.

I need to a crawl space vent cover! I believe it lets in a lot of cold air...I'm cold! :)
Vicinity of Jackson St. NE in Washington
Hi there- At the moment the main thing I am looking for is to discuss moisture in the basement. I think at the moment I am just looking to have a sump pump replaced. There is a sump pump in the basement (was here when we bought the house 2 years ago). It was running past when the water was out of the basin and I unpluggged it to stop it. Now it sometimes comes on, sometimes doesnt when I plug it in. Is this a job you would do? I do think we may be looking for other work in the future. --Gretel

Waterproof basement
Vicinity of Kanawha St NW in Washington
We have major water ingress in our basement resulting from basement renovation
Vicinity of Kansas Ave NW in Washington
We have a low spot on the left side of the house near the back, about 3 feet away from the foundation where water collects after heavy rains. Occasionally, if rain is especially heavy and prolonged, water will come into the basement near the wall floor joints. That happened in September during one of the heavy rains from a tropical system. Currently, water is collecting there badly and we are wanting to understand our options for a solution. French drain? Sump pump? Re-grade yard? There are many options to consider and we would like someone to come out and go over it with us. I also have a video and photos of what it is like currently with the heavy rains right now. Thanks

Vicinity of Kentucky Ave SE in Washington
When it rains hard, I get water on the floor in the basement that comes from a couple different areas/corners. This has been reduced by the way I've hooked up the gutters/draining system outside, but it still happens

We are closing on this house next month. During the home inspection moisture intrusion in the basement was noted. We'd like to determine what can be done to mitigate future problems.
