    Restoration with Waterproof Products = No More Mold in a Baltimore, MD Basement

    This basement was getting wet during storms which made the drywall and carpet moldy. Drywall and carpet are made of organic materials so they easily get destroyed by water and mold damage.  The smell was noticeable and something had to be done.  

    Basement Systems USA, Inc. went in and first removed the carpet and the bottom of the moldy drywall and did some mold remediation.  The next step was to install the WaterGuard drainage system around the perimeter so that the basement would no longer leak.  The WaterGuard was connected to one of our SuperSump Systems which include a battery back-up pump so that the water can be pumped out even during power failures.  

    Once the basement is mold-free and no longer in danger from water seepage, we could start putting things back together. But we would never use organic materials like drywall or carpet to repair the basement.  A special waterproof and inorganic wallboard called Everlast Walls was used to make the basement look beautiful again.  Everlast Walls is made of nonorganic material and is guaranteed for 50 years against water and mold damage.  We also used a special waterproof wood-look flooring so that there would be no danger of water damage. 

    The result is easy to see. The basement is not only dry and looks amazing, it has been repaired with the right building materials so that there is no chance of water or mold damage in the future. Another job done right.

    New EverLast Basement Window and WellDuct Window Well Drain in Baltimore City, Maryland

    This old, cold, and leaking window needed to be replaced, so we installed an all-vinyl, energy efficient EverLast Basement Window. These windows are airtight but easy to open. When unlocked, both panes can be removed for cleaning or for passing objects through – like a ladder or another item you’d rather not carry through your house. 

    We also installed a WellDuct window well drain in the window well outside. This drain is connected into the interior WaterGuard system to prevent window well flooding. We also wanted to prevent vapor transmission through the walls, so the ThermalDry Wall vapor barrier was installed. Not only does ThermalDry Wall help to lower relative humidity, it has a radiant shield which reflects up to 97% of the heat back into the basement.

    Sandra R. of Baltimore, MD

    Customer Testimonial

              Basement Systems USA recently installed a Super Sump system and waterguard track in my basement and an outside underground sump pump drain pipe with ice guard and lawnscape outlet. The crew did an excellent job installing everything and cleaning the work area when finished. My only criticism was that, after installing the new discharge pipe, they didn;t cement over the hole they'd made in the concrete wall. I called the service dept and the manager said of course they'd fix that. I also asked if the outside drain pipe could be shortneed so the lawnscape outlet would drain better over the lawn. Again, he said yes because they wanted me to be satisfied. Mike Dyer was the technician who came to do the additional work, and I can't praise him enough. He d id a beautiful job of cementing over the hole in the basement wall-- you'd never know it was there. He shortened the outside drain pipe, refilled & tamped down the trench, and then went the extra step of obtaining & installing a popup outlet that works better in my yard. Mike also installed an 8' chute on the downspout to drain water away from my patio. Basement Systems did not charge me for any additional work. They mean it when they say they want their customers to be happy. I would recomment them without hesitation.

Affordable, Certified Waterproofers for greater Baltimore, Philadelphia, West Chester, and Lancaster

Basement water problems are as old as the structures themselves. Water will leak into a basement through any opening it can, including your walls, floors, and the joints between them. Water can even pass through the concrete itself -- which is one reason why basements are notoriously damp, humid spaces.

Other companies might try to sell you on inferior basement waterproofing solutions. Our products have been developed, patented, and perfected by Basement Systems®, Inc. -- the world's largest network of basement waterproofing contractors.

Whether you live in Philadelphia, Baltimore, Ellicott City, Wilmington, Upper Darby, Parkville or Lancaster, our basement experts will show you how we can customize your waterproofing solution to keep the basement dry all the time!

Exterior Excavation

Heavy equipment is brought in to dig out the entire perimeter of the basement. New drain lines are installed, and sometimes a waterproof coating is applied to foundation walls. This waterproofing strategy is expensive and often damages lawn and garden areas. Exterior drains are prone to clogging with silt and roots over time.

Interior Subfloor Drain

This drain line is installed underneath the basement floor, just inside the foundation walls. The hidden drainage system brings water to a sump pit, where a sump pump automatically pumps it outside. Also known as a French Drain, this system is not prone to clogging; it’s reliable and easy to service.

Interior Baseboard System

A hollow plastic baseboard is installed along the base of basement walls to form a drainage channel that directs water to a sump pump system. A baseboard-type drainage system is sometimes recommended when the basement slab is too thin to accommodate a French Drain.

Negative-side Sealant

This waterproofing technique involves "painting" basement walls and floors with a waterproof, cement-based coating that's supposed to seal out moisture. Even when applied correctly, this thin membrane usually fails in response to prolonged hydrostatic pressure from outside the foundation.
