Whatever the cause of your wet basement, NV Waterproofing & Foundation Repair has a solution.

Crawl Space Encapsulation & Repair in Bethesda

Crawlspace Supports and Vapor Barrier

We sealed and stabilized this crawl space with our innovative tools.

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
  • Dehumidifiers
  • Sump pumps
  • Access doors and access wells
  • Crawl space support jacks

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.

Basement egress window
Vicinity of Sangamore Ct in Bethesda
I am in a middle unit townhouse. The bottom floor is below grade in the back (front door is ground level in front.) I have a drainage issue caused by the overflow of downspouts on the 2nd level as well as 20+ years of general water seepage into the back wall/floor. There is a fireplace in the middle of the wall. I need some help adjusting the drainage in a very tight spot in the back of my yard as well as waterproofing and repairing the wall/floor of the back room on the basement level. If this is something you can do, I would like to schedule an estimate. Thank you
