The Experienced Basement Waterproofers in Germantown

NV Waterproofing & Foundation Repair has been in business since 1986. In that time we have waterproofed and repaired thousands of basements and foundations. We have seen any basement water issue that you can imagine. We know exactly how to tackle any problem from clogged drain tiles to hydrostatic pressure behind your foundation walls. We will make sure that your basement is as dry as a bone!

When installing a waterproofing system, you want to make sure that it has a sump pump that you can trust. These pumps are the heart of the system because they discharge the collected water away from your home. Our pumps are designed to handle a high volume of water and to last through heavy storms. We even install battery backup pumps in case of a power outage. We want to make sure that homeowners don't have to worry about their basements ever again.

Our other basement waterproofing services include:

  • Wall Coverings 
  • Dehumidifiers
  • Basement Window Wells
  • Crack Repairs
  • French Drain Systems

Your Expert Foundation Repair Contractor

Carbon Armor Wall System

We reinforce bowing walls with these carbon fiber strips that are stronger than steel.

Many homeowners in Germantown don't realize that they have a foundation issue until massive damage has occurred. The early warning signs include settling floors, bowing walls, jamming windows, and cracks in the drywall. It is easy to mistake these problems as being small issues that are unrelated. Unfortunately, if they go ignored, you will have a more serious problem on your hands. We at NV Waterproofing & Foundation Repair can help you stabilize your home and restore your foundation's integrity. Our piers will keep your foundation locked in place. We have wall braces and anchors to keep bowing walls from moving. We also have support jacks to keep floors from sagging over crawl spaces. You can count on us to have the answer to your foundation problems.

Encapsulating Crawl Spaces in Germantown

Crawl spaces have always been a natural magnet for humidity issues. To avoid this, they were constructed with ventilation so that damp air could escape. Science has shown that homes pull air up through them. That means that air is drawn into the crawl space from outside and then sent through the main living space of the home. The building itself will fall victim to structural damage from the humidity and the occupants can develop serious health issues from mold growth.

In order to fully stop crawl space humidity, we seal the walls and floor of the area with our deluxe vapor barrier. We install our quality, energy efficient dehumidifier to eliminate any lingering moisture. The home now has a conditioned space under it that makes it more comfortable and more affordable to heat and cool.

If your basement, foundation, or crawl space in Germantown is having any problems at all, you can count on the experts at NV Waterproofing & Foundation Repair to give you an estimate to restore your property!

I recently noticed after a heavy rain that a portion of my basement wall was wet. I'd like to have this area inspected because there may be a crack that needs to be sealed/waterproofed.

Water leak in the basement

Noticed a crack in the outside wall. Please see attached photos.
Project Location: Germantown, MD
The floors are uneven, bouncy, and sagging in places in our home. We believe this is happening because the floor joists have large holes cut through for the hvac. The second floor of our home has about a 1 inch slope and we would like to get it fixed. Also, we got water in our basement but have no idea where it is coming from or if we have a sump pump or what can be done about it.

Low spots in floor and sagging exterior front of house
Project Location: Germantown, MD
Hello, I moved into my home 4 months ago. It is about 30 years old. I noticed a small puddle of water in the mechanical room in my basement. Upon further exploration, it seems that an area of the cinder block foundation has been collecting moisture for awhile and the exterior ground outside of this room is continually muddy. In addition, the back yard is generally muddy and there's a sloped area in the front yard that has issues with erosion and "naked" spots. I would appreciate having someone come out to take a look. Thank you, Skye

There is a retaining wall in the back yard that requires additional drainage. There is also a large retaining wall on the side of the driveway that needs repairing and drainage updating to the front of the home. There are large cracks down multiple areas of this wall.

Crack in basement floor

Water is leaking to craw space in the basement on a single point. Junction with deck. Seems to locate under the door to patio
Project Location: Germantown, MD
• Repair entryway; mortar joints between bricks are cracked/eroded. • Repair garage base; cement is cracked/eroded.
Project Location: Germantown, MD
The way our gutters drain and the location of the cement exterior stairs to our basement is causing a lot of water to flow along one side/corner of our house. We haven't had any leaks, but we see effloresence on the interior basement wall. We'd like to have a French drain (or whatever is most appropriate) installed to redirect the water away from our foundation. We're not sure if you provide services like that, but wanted to reach out and hear your thoughts. Thanks!
