Havre De Grace's Basement Waterproofing Contractor

Basement Systems USA is the local, family owned contractor in Havre De Grace 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 Havre De Grace

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 Havre De Grace waterproofing systems come with lifetime warranties. 

Basement Finishing & Remodeling in Havre De Grace, 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 Havre De Grace 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.

Before and After Pictures from Havre De Grace

This customer travels often for work and was concerned about his old sump pump system failing while away. No fear! We installed a TripleSafe sump pump system. The Triple Safe has three pumps. Pump 1 does the majority of the pumping. Pump 2 kicks in if Pump 1 needs assistance during a severe storm, Pump 3 is the UltraSump Battery Back-up system. As an added precaution he also had us install an Ice Guard. In the event the end of his discharge line freezes in cold weather, his TripleSafe sump pump will still be pumping water outside keeping the basement DRY!!

Job Stories From Havre De Grace, MD
Structural Problems Repaired in a Home in Havre De Grace, MD

This home had many problems.  The walls were bowing and needed reinforcing and the joist where sagging.  In addition, the stairwell was flooding over into the basement.  

First we installed GeoLock Wall Anchors to stabilized the foundation wall.  Then we installed SmartJacks to reinforce the joists.  Both products are made of galvanized steel so the will not rust or corrode.  They include a 25-year nationally backed, transferable, guarantee against failure.  

We also broke out the stairwell pad and installed a TrenchDrain System with a new concrete pad to prevent flooding.

There is water pouring out of my basement wall when it rains. A sewage pipe is exiting through it and the previous owners appear to have sealed the opening (a large rectangle) with gravel, newspaper, and a vinyl covering. The water is ground water and not from the pipe. I need the hole filled in.

Please provide me with a free repairestimate for a hairline crack in an interior basement foundation wall. Thanks
Project Location: Havre De Grace, MD
I live in a duplex in downtown Havre de Grace. The gable side is partially cinder block and field stone. That wall leaks as to be expected and is not really to big a concern. It is mortered field stone after all and the weeping is not that bad. My main concern is the adjoining wall for the other house is constantly wet and causes pools of water to form. The floor is not level so it can't travel to the French drain. I also have a concern that my neighbors basement is holding water and is causing my problems. I would like to get this assessed and find possible solutions.

I have a large basement in need of waterproofing. From previous experience I would say it most likely needs to be dug out & waterproofed. I would like to set up a time and date to recieve a free Waterproofing estimate.
