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.

We offer a variety of crawl space solutions, including:

  • Vapor barriers

  • Sump pumps

Warrantied Foundation Repair in Bethesda

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 Bethesda, MD and the surrounding areas.

I have two problems. First is cracked bricks and mortar on north wall of my home. Second is during the heavy rain on Friday, I got water seeping into the utility/laundry room. We put down newspapers and they got very wet. Please let me know what you can do. A neighbor suggested I should get a structural engineer to look at this situation. Do I need to do that? Please let me know how to proceed. Thank you.

We are having problems with a wet basement and would appreciate an estimate to fix them. We thought we fixed the problems in 2003 but they reappeared in 2013, which we again addressed. Now, after another 10 years, they have once again returned. We are hoping for a more permanent solution.
