Claymont's Basement Waterproofing Contractor

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

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 Claymont waterproofing systems come with lifetime warranties. 

Basement Finishing & Remodeling in Claymont, 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 Claymont 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 Claymont

Customer had plans to turn the basement into a Daycare, but before that could be done, the moisture collecting on the walls, had to be taken care of. We came out and installed a CleanSpace Vapor Barrier which will direct any water seepaing in through the walls, down to the drainage system. Not only does the vapor barrier direct moisture coming in from the outside, but is also a great way to prevent humidity in the basement.

We had an engineer check crawl space and discovered rotten beams. Got an estimate, it is very high and we can't get financing. Contractors all need money up front!

With all the heavy rain we've had the past 2 days our basement started leaking. We've been in the house for 2 years and it has never leaked before. One point of entry is around the gas line that comes in to our house. I saw water activity leaking from the seal around the pipe. There are a few other mystery spots that we can't tell where the water is coming from. We would like someone to come out and assess the situation and get a quote on what it would take to fix it. Thank you!

My crawl space is wet (sometimes has puddles), and the vents are windows that need to be replaced (rusted frames so they don't close properly).

We have a 60+ year old home. It leaks in one area during heavy rains. We have another area with a constantly weeping wall. The previous owner or owner prior to them dry locked the basement although it is dry/cracking/white powder in some areas. We appear to have a french drain although we are not sure it is working properly. We have a working sump pump. We recently had concrete work done on the entrance steps into the home and hand sidewalks removed that were tilted towards the home, however we still had water during the last heavy downpours.
