Our team was recently contacted by a client in Burke, VA; who was experiencing a substantial water leak in their basement. As evidenced in the pre-intervention images, the severity of the leakage necessitated the removal of both carpeting and trim. In response to this issue, our team promptly implemented a comprehensive waterproofing system throughout the entire perimeter of the basement. This robust solution included the strategic installation of a Cleanspace vapor barrier, a Waterguard drainage channel, and a TripleSafe sump pump system, thereby ensuring maximum protection against future water intrusions.

Job Stories From Washington, DC
Basement Waterproofing in Washington, DC

A homeowner in Washington, DC, contacted us, deeply concerned about water infiltrating their finished basement in an eighty-year-old house. They reported significant issues: bubbling painted walls, water accumulation on the floors, and a persistent smell of mold and mildew, emphasizing their desire for a dry and secure basement space.

Our technical advisor promptly visited the property for a comprehensive inspection.

The water damage to the basement was found to be quite severe, prompting us to propose a durable and fully warrantied solution to address their concerns. During the demolition phase, our production team uncovered extensive moisture penetration in the cinderblock walls of the basement. To combat this, we implemented our Waterguard system a trench drain solution designed to redirect any future water seepage away from the basement via the Super Sump pump and out of the property. Additionally, we installed a CleanSpace vapor barrier to block mold and bacteria, significantly lowering humidity levels in the basement. This system was complemented by the Sanidry Dehumidifier to ensure maximum protection against moisture.

Furthermore, to address water ingress through the basement windows, we upgraded the well drains with an improved drainage system. The customer was thrilled with the transformation, looking forward to renovating their basement once more, now safeguarded against water damage.

Crawlspace Encapsulation in Washington, DC

A homeowner in DC had just moved into her new home. When purchasing the home, she noticed that the crawlspace had not been properly taken care off by the previous homeowners. It had falling insulation, high moisture levels and a deteriorating piece of plastic on the floor. After seeing what NV had to offer, she decided to move forward with the project. Now, she has a healthy and odor free home because of her encapsulated crawlspace.

Wall Support in Washington, DC

A DC homeowner called out NV Waterproofing & Foundation Repair because they needed immediate help. Their garage foundation walls were failing. Both walls were bowing and had severe stair-step cracks. The homeowner figured he would have to do a complete demo & rebuild but after his inspection with NV, he learned that was not the case. Using our signature PowerBrace system, this DC resident was able to secure his foundation walls without the hassle of a complete demo. Just weeks after the appointment, this garage was fully secured and pushed back.

Waterproofing Basement in Washington, DC

A customer in Washington, DC had been experiencing basement water seepage during several storms. Knowing that these hard rains were going to continue, they decided to have a professional come out and take a look. After moving forward with NV Waterproofing, they had an interior waterproofing system installed. This system included a top-of-the-class SuperSump, WaterGuard, and our CleanSpace Wall System. Now, this customer has the peace of mind that water will never come into his basement again.

Foundation Piers in Washington, DC

A customer in Washington, DC who owned a 1916 Townhome was experiencing a jammed front door due to settlement. After having one of our professional consultants out for a visit, he learned that the best solution would be foundation piers. Foundation piers are the only permanent solution for settlement because piers are able to reach the deepest layers of soil, like bedrock. Then, the home rests on the piers which rest on the sturdy bedrock. Since having the piers installed, this homeowner made the necessary changes needed on the front door and has had no issues since!

Window Wells in Washington, DC

A customer in Washington, DC had been dealing with water intrusions in their basement. One area they were experiencing water was by their window wells. After having NV Waterproofing & Foundation Repair out for an inspection, they narrowed down the intrusion area. They also discovered that just putting in new window wells does not guarantee a dry basement. The only way to make sure the area would never get wet again was to change the wells and also install an interior drainage system. Since their installation, they have had several spots of rain without water in their basement. They cannot believe how much sunlight comes through their brand new window wells!

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.

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.

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.
