Did you know that your crawl space could cause musty odors and cold floors upstairs? If you have a vented crawl space with moisture, mold, mildew, rot, or pest problems, we can help.

At NV Waterproofing & Foundation Repair, we use the CleanSpace encapsulation system to seal your crawl space from outside air. This will help stop moisture and mold problems.

  • Vapor barriers

Warrantied Foundation Repair in Clifton

Foundation problems only get worse over time. If you notice cracks in your foundation, basement walls that are bowing or any other sign that something's not right, let one of our foundation specialists take a look - you'll be glad you did. The sooner you take care of your foundation, the less money it will cost you in future repairs.

Some common signs of foundation problems are:

  • Sagging floors and floor cracks
  • Wall cracks
  • Bowing walls
  • Sticking doors and windows
  • Tilting chimneys

With patented helical piers, push piers, wall anchors and crawl space jacks, we can handle any foundation problem. Normal settlement can cause foundation cracks, but they could also mean a serious structural problem.

We never recommend a solution that you don't need. Our goal is to educate you on all the options and let you choose the best solution for your needs and budget

To schedule your in-home consultation with a free written estimate, contact us today! We offer our basement waterproofing, crawl space repair and foundation repair services in Clifton, VA and the surrounding areas.

Job Stories From Clifton, VA
Exterior Waterproofing in Clifton, VA

A homeowner in Clifton, VA, reached out to us, troubled by water infiltrating their home's lower level. Our detailed property evaluation revealed a foundational crack as the culprit behind the unwanted moisture in the basement. Our approach to resolving this issue involved sealing the crack to prevent further water seepage and implementing measures to redirect water away from the foundation walls. This included cleaning the gutters and installing an extra 4" of buried downspout to ensure efficient water diversion. The homeowner was pleased with the effective resolution of the problem.

Water infiltration in crawl space

Whenever there is a lot of rain, water is leaking through in my basement and I am not sure where the origins of the leak. It is leaking into my floating vinyl floors and I can see water pooling in the crawlspace where my sump pump is.

We had a foundatation assessment done back in 2010 and unfortunately can't find the report. I do know our foundation was found to be structurely sound. What we are attempting to fix is the foam board around our house. It is starting to become exposed and is a cause for concern. We would also like a review of our vapor covering in our crawl space to see how that is holding up overtime. Our main concern is the foam board. Everyone that has looked at it says easy fix, but we can't seem to find someone with the expertise to fix it. Thanks! I have pictures that I can send if needed.
