This customer wanted to have a code-approved Egress Window Well installed in their home so the basement could be finished and used as extra living space. 

We installed an Egress Rockwell System because it is by far the best egress window well system available on the market. We also installed a WellDuct window well drain to guarantee that the water in the window well will never flood into the basement.

This customer wanted to sell their home but needed to get it waterproofed first.  We removed moldy paneling and replaced their inadequate sump with a SuperSump.  We installed WaterGuard to control the water issues and installed SilverGlo insulation on the walls with inserted studs so the customers can replace his own panels.

This customer had a finished basement and started to notice cracks along the drywall, concerned this could be a major issue, they reached out to us to assess. 

When arriving at the property, the drywall had already been removed and you could see a noticeable horizontal crack going through the foundation wall. Our solution for this was our Carbon Armor Wall Stabilization Straps. 

The Carbon Armor system is 10x stronger than steel but flexible enough to form tightly against the basement wall. The straps are secured to the floor joist and is ideal for quickly stabilizing bowing walls

Bel Air's Basement Waterproofing Contractor

Basement Systems USA is the local, family owned contractor in Bel Air for waterproofing, finishing, crawl space repair and mold removal. With over 75 years combined experience and a full-time, professional staff we are ready to serve you and improve your home. 

Basement Waterproofing & Crawl Space Repair in Bel Air

Flooding, water seepage or even high humidity can quickly result in mold growth and water damage in your basement or crawl space. We prevent this from happening by installing an interior drainage system in the basement that is connected to a high volume sump pump. Any water that makes it to the basement is collected and pumped out of the home without you even noticing. 

Just like the basement, in the crawl space we similarly place a sump pump system and dehumidifier to prevent water issues. The entire area is encapsulated with vapor barrier to prevent mold growth. Our crawl space system comes with a 25-year warranty. 

We Provide:
  • Basement Waterproofing
  • Crawl Space Encapsulation
  • Exclusive, Patented Products
  • Humidity Control
  • Structural Repair
  • Basement Egress Windows
You Receive:
  • Permanently Dry Basement
  • Clean Protected Crawlspace
  • Protection against Mold
  • Improved Home Value

If the walls of the basement or bowing inwards we install wall anchors or braces to straighten the walls. If the floor above the crawl space is sagging we install SmartJack support jacks to raise the floor back to a level position. Our Bel Air waterproofing systems come with lifetime warranties. 

Basement Finishing & Remodeling in Bel Air, MD

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring
  • Basement egress windows

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors

Unlike the average Bel Air contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

Beautiful, Bright Egress for Finished Basement

This job in Bel Air, MD needed an egress window for their finished basement.  The job required removal of bushes and drywall, but everything went smoothly.  The beautiful RockWell window well looks amazing and much better than the standard metal contractor grade wells that always rust and leak.  We also installed a drain in the bottom of the window well to prevent flooding. The basement is now bright, but more importantly, safe!

Finished Basement with Crawlspaces in Bel Air, Maryland

Before we finished this basement we had to deal with some problems first.  This basement had several crawlspaces that that had moisture and no insulation.  We installed CleanSpace barrier on the floor of the crawlspace to prevent vapor transmission.  We also insulated the walls and rim-joist of the crawlspaces but not with fiberglass insulation because that attracts mold and becomes ineffective over time as it absorbs moisture.  Instead we used Silverglow foam board.  We also installed a SaniDry Dehumidifier to keep the humidity at an acceptable low level.  

Then we used our TBF Everlast wall panel system to finish the basement and it came out great.  Not only does it look good, it comes with a 50-year guarantee against water damage and mold growth.  We also fixed the stairs and installed Thermal flooring that makes the basement floor look good and creates a warmer floor surface. The basement looked great and is now ready to use.

Basement Finishing in Bel Air, MD

When a homeowner needed a higher quality basement, we were there to help. After eliminating the mold in the basement, we installed our reliable Everlast basement windows and Rockwell window well to keep moisture and soil out. We installed our Wellduct and ThermalDry wall systems to prevent water damage by catching and sending any water to the drainage system. The SaniDry dehumidifier will also control the humidity and air quality in the basement so that there is no risk of moisture, mold or odors. The homeowner is now happy with a basement that can be used.

Waterproofing and Mold Remediation in Bel Air, MD

A customer had a nasty problem with their wet and moldy basement. We fixed the problem with our successful Spot Mold Treatment, removing all mold from the space. We then went further by installing the state of the art WaterGuard XL waterproofing system which captures water that leaks through the walls and floors of their home. Now, the customer has a dry, clean space with no worries of damp or moldy odors.

I would like to get an estimate to waterproof a portion of my homes foundation. When heavy rain occurs I get small amounts of water in my basement. It appears that the water is traveling down my driveway which is alongside my home. I would like to discuss options to remediate this issue and divert water away from my home.
