Water and mold destroyed this bathroom.  After dealing with the source of the mold by installing waterproofing system, we renovated this horrible bathroom into a new, clean, and dry space for the customer to enjoy.  In the process, we used inorganic materilas so that there would be no chanse of the mold coming back.

This basement was getting wet during storms which made the dry wall 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 wall board called EverlastWall was used to make the basement look beautiful again.  EverlastWall 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 the is no chance of water or mold damage in the future. Another job done right.

These are before and after pictures of a church that had such a bad moisture problem in their crawlspace that rot destroyed the floor.  The whole floor had to be removed, but before replacing it, the owners were smart enough to call Basement Systems USA to install a new CleanSpace system, complete with a SuperSump and SaniDry Dehumidifier so the new floor would be protected.

Job Stories From Baltimore, MD
Basement Finally Dry in Baltimore, MD

This old home in Baltimore city had a fieldstone foundation which leaked everywhere.  We installed the WaterGuard basement waterproofing systems around the perimeter.  The system was connected to a SuperSump system which will automatically pump the water out of the house.  A WaterWatch alarm will monitor the pump and notify the homeowner if the pump fails.  We also installed the CleanSpace vapor barrier on the walls to reduce moisture transmission through the foundation.  Finally, we also installed the larger TrenchDrain in the stairwell with a new concrete stairwell pad. 

Commercial Building in Baltimore City, MD Waterproofed

This commercial building had a basement that was remodeled in the 50's.  It leaked during almost every storm and the water had caused mold problems on the old wall sand flooring. 

Basement Systems USA, Inc. went in and removed the flooring and the old walls to remediate the mold.  Then we installed the WaterGuard waterpoofing system with SuperSump.  The discharge line for the SuperSump was tricky.  We had to break open the sidewalk and extend the pipe to the street so that there would not be any ice on the sidewalk in the winters.  

When the waterproofing was done, we replaced the walls with moisture resistant DryWall and waterproof flooring so that there was no chance old mold or water damage.  

Foundation Repair, Waterproofing, and Finishing in Baltimore, MD

This basement had lots of problems. There were structural problems plus water leaking issues and the customer also wanted to re-finish it. The first thing we did was install CarbonArmor on the foundation walls to guarantee that they would no continue to crack and bow.  Then we installed a SuperSump system with WaterGuard  to prevent water seepage.  Once the waterproofing and structural repairs were completed, we removed all the old paneling and installed the TBF EverLast wall system. TBF comes with a 50 year guarantee against water damage and mold growth.  Once the walls were up, we installed MillCreek waterproof flooring and an inorganic and mold resistant drop ceiling.  The job came out great, but more importantly, the right materials were used. This basement will not have mold and odor issues in a the future. 

Basement Waterproofing in Baltimore, MD

This basement did not have a drainage system, but it did have an old sump pump and drain outside of the stair well that was not functional. We upgraded the sump pump with our SuperSump system, and installed our WaterGuard interior drainage system along the basement walls. This will guarantee that the water will direct from the drain system and into our sump pump for a safe and dry basement. After, we ripped out the old stairwell pad and drain, and replaced it with the correct size of our TrenchDrain. Another Job well done and another dry basement. 

Basement Waterproofing and Mold Removal in Baltimore, MD

A homeowner with a leaky basement and mold problem called us to help. We used our Spot Mold Treatment to rid the space of all signs of mold and then replaced the existing damaged walls with our TBF Everlast walls that are guaranteed to stay mold and moisture free. To keep the basement staying in great condition, we added more of our quality products. The SuperSump sump pump was installed to prevent water from getting into the home and the Cleanspace wall system, WaterGuard and DryTrak systems will be used to capture and send any leaking water to the drain as will the ThermalDry Wall System which improves the basement’s comfort and energy use. The homeowner is very happy with the improved and guaranteed dry basement.

Waterproofing with Patented Products in Baltimore, MD

This customer wanted to fix his leaking basement and ensure it stayed dry even in the winter months. Our foreman and his team installed many of our top products to achieve this goal. While the SuperSump sump pump will pump out all unwanted water from the basement, the TrenchDrain and WaterGuard waterproofing systems were installed to guarantee the space stays dry, capturing any water that gets through the cracks and sending it to the pump. We used our ThermalDry wall system to rid wall seepage and help control the humidity. In addition, we added the UltraSump III as a backup sump pump and the IceGuard sump pump discharge line system which will prevent the basement from flooding if the pipes freeze during the winter. With all of these quality products, the customer is now happy with his dry basement and is confident that it will stay that way.

I own a city home in Canton. The basement has a previously unaccessable dirt floor crawlspace. I would like to have it looked at. I also occaisonally have issues with my sump pump not draining completely. Access is limited to the area to a drywall panel you can access. Whomever inspects this, will need to be on the slender side to access it.

I want to finish part of my basement to accommodate for a bedroom and full bathroom. In order to make these rooms legal and up to code I will need to add height (currently 6'4, and need 7'). Therefore need to dig out the foundation of basement. I also plan to create a designated area for a utility room, but I don't think that portion of the basement needs to be dug out. Looking to understand the process of a project like this and get an estimate for work involved. Thanks!
