Wilmington's Basement Waterproofing Contractor

Basement Systems USA is the local, family owned contractor in Wilmington 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 Wilmington

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 Wilmington waterproofing systems come with lifetime warranties. 

Basement Finishing & Remodeling in Wilmington, DE

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 Wilmington 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.

Job Stories From Wilmington, DE
Mold and Joist Rotting in Crawlspace in Wilmington, DE

There were several problems with this complicated, multi level, home in Wilmington, DE.

First, the deck boards on the front of the home were painted closed and no longer allowed water to drain in between them.  As a result, the customer would have several inches of rain build up on the deck, which then leaked into the home and caused the lower level drop ceiling to get damaged.  To solve this issue, we had to rip up the old deck boards and replace them with new, pressure treated boards with spaces in between each board so that the water could properly drain.  Problem solved.  

There was also a problem with sub-flooring in the basement.  There was no vapout barrier on the dirt floor below the plywood.  This caused a constant moisture problem which resulted in the floor and joist rotting.  We ripped out the old floor and the joist and installed a drainage system along with the CleanSpace Vapor barrier so that the space would be dry.  No more high mosture levels under the floor.   Then we reinstalled the joist and the floor decking. 

There was also an adjacent crawlspace with mold all over the joists due to high levels of moisture.  The primary reason for the mold was that the existing vapor barrier was only 6-mill poly plastic, which could not keep the moisture from the ground from leaking into the crawlspace and causing high humidity levels.  We did a full mold remediation job on the whole CralwSpace.  A new SmartSump was installed to make sure we could control water seepage under the vapor barrier.  We installed the CleanSpace Vapor Barrier  to make sure that the ground was properly sealed off.  We also installed the SaniDry Sedona dehumidifer to make sure that the remaining air in the crawlspace would always stay dry.  We spray foamed the ban-board/sil-plate area and some above ground framed walls to keep the cold air out.  We also replaced the old, leaky, crawlspace door with the airtight EverLast door to keep the humid and cold air out.  

To finish it off, we repaired the water damaged drop ceiling on the first floor. This job tool about 7 days and came out beautifully.  Most importantly, all the customer problems of mold, rot, high humidity, water seepage and bad insulation have been resolved.

Crawlspace Encapsulation in Wilmington, DE

This little crawlspace was moldy, damp, and cold.  The problem was that it was vented to the outside which lets cold and wet air into the crawlspace. It also had fiberglass insulation in the ceiling, which is the worst product to install in damp areas. Fiberglass  is organic and will suck the moisture out of the air and then grow mold. The floor was also missing a vapor barrier. This means moisture from the ground can evaporate into the crawlspace. We had the solution; we closed the vent and removed the fiberglass insulation in the ceiling. Then we insulated the perimeter walls with SilverGlow foam board. We also installed Drainage matting and the CleanSpace vapor barrier over the floor. The crawlspace is now t clean, dry, mold and odor free.

Wet Basement Turned Into Dry Usable Living Space in Wilmington, DE

This basement was very wet and damp and looked like an un-usable dungeon.  It would be a bad idea to use traditional basement finishing matrials like drywall in this basement because you would have mol din no time.  

We first made sure that the basement was waterpoofed with our Wateguard waterpoofing system.  The we used in-organic materials to finish the basement.  TBF everlast walls not only look beautifull, they also com ewith a 50-year guarantee against water or mold damge.  The flooring is also waterpoof and even the ceiling tiles are made of an inorganic material and come with a30 year guarantee.  The space was small but it turned out great.  Can you imagine the difference in home value this job made?

Crawlspace Encapsulation in Wilmington, DE

To ensure his crawlspace stays comfortable and dry, a homeowner called us for help. We got right to work, first ridding it of mold and the current insulation. We then insulated the crawlspace with our quality SilverGlo and Terra Block products. We also installed Cleanspace which will direct any unwanted water seepage and send it to the drainage system. These products keep the crawlspace dry while also improving energy use and comfort. The homeowner is pleased with the new insulation in his crawlspace and thinks of it as new.

Waterproofing a Leaking Basement in Wilmington, DE

This customer’s leaking basement was a big problem. We installed our SuperSump sump pump for him which will pump up to 2280 gallons an hour while preventing further water leakage or other outside elements. Our TrenchDrain and WaterGuard systems will capture water seepage and take it to the sump pump so that the basement stays dry even in heavy weather conditions. The ZenWall basement paneling system also provides walls that are a moisture barrier, capture water seepage and improve energy efficiency in the basement. Thanks to our team, our customer will enjoy his basement.

Crawlspace Project in Wilmington, DE

When a homeowner was experiencing crawlspace flooding, we came to the rescue. We were able to install our quality SmartPipe crawlspace drainage system along with some of our other dependable products to prevent crawlspace flooding. The homeowner now uses the SmartSump system that will alert him of any problems it's experiencing as well as the Cleanspace vapor barrier that prevents moisture and outside elements from entering his crawlspace. The homeowner also chose to have us install a new SaniDry dehumidifier as well as our IceGuard discharge system which will ensure his crawlspace stays dry in the winter months. By installing all of these products, we were able to prepare this customer for any situation, protecting his crawlspace from mold, flooding and other outside factors.

Possible Spalling on the inside cinderblock wall of basement foundation. Tiny crack on inside of cinderblock wall above the ground on the corner of house foundation. I would like an expert's opinion on if there is a serious issue that needs to be remediated. We moved into the house in 2018 and have never had any water inside of the basement or the appearance of moisture on the walls. A structural engineer evaluated the home in 2020 and found no structural integrity issues. The wall where the apparent spalling is appearing is directly behind the dryer, and I am not sure if the escaping moisture and heat from the back of dryer is creating or contributing to this issue. The house has settled over the years and that is evident and I want to make sure that everything is okay. I want to repair the walls in the laundry area Of the basement and seal/waterproof them.
