Berwyn's Basement Experts

Basement Systems USA is the local, family owned contractor in Berwyn for waterproofing, 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

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
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 Berwyn waterproofing systems come with life-time warranties. 

Mold Removal & Remediation

At Basement Systems USA, we provide full mold remediation for basements, including air sample testing. Our company has the ability to not just remediate the mold, but also remove the source of the mold, which is moisture. Unlike other mold remediation companies, our background in basement & crawlspace waterproofing allows us the make sure that the mold won't come back after it has been remediated. We are also AMA Certified.

Our Services Include :

  • Mold & dust mite control           
  • Dehumidifier Installation
  • Crawl Space Encapsulation
  • IAQ 6000 Mold Encapsulant


  • Black Mold Removal
  • Dry rot cleaning & repair
  • Shockwave by Fiberlock Disinfectant & Sanitizer
  • TBF Waterproof & Mold Resistant Wall Boards
  • Negative Air Machine Installation

Need to install an egress window and potentially need to cut the concrete
Vicinity of Bridge Avenue in Berwyn
The property is the Berwyn Fire Company. Our gym is in the basement. We get water during extreme rain conditions. I believe we need a sump pit and pump and perhaps additional sub-slab drainage.
Vicinity of Francis Ave in Berwyn
I have water penetrating the concrete walls and causing paint to flake off. However an inspector came out and reports that I have mold throughout my basement. They want to charge $15,000 for french drain, furniture removal, panel wall removal and mold remediation. Would like an estimate tomorrow, Friday or Saturday if possible.

Water leak in basement from concrete wall
Vicinity of Conestoga Road in Berwyn
My sump pump continues running until I pull the plug.
Vicinity of Daylieview Road in Berwyn
I need an egress window out in my basement
Vicinity of Coldstream Drive in Berwyn
Good morning. We have a roughly 1,000 sq ft basement (standard colonial) that doesn't have a proper french drain. No leakage, but the HVAC/Dehumidifier just drain to a hole by the wall, and the built in cabinets have mildew behind them. Basement was finished probably 20-25 years ago. I'd rather have a useful space that I'd enjoy hanging out in. We'd like gut the basement, put a proper french drain/new sump pump in, waterproof it, and finish it/remodel it, while also putting in a new full bathroom downstairs. If you guys can do all of the above let me know if/when we could schedule an estimate. Thank you, Peter Toscani
Vicinity of Sugartown Road in Berwyn
We are considering a waterproof system installed in our basement. We occasionally get low amounts of water during heavy rain. The basement is very utilitarian as it is in a home 112 years old. If there was a way to have any area that could be "finished" for the children to have a play area(budget will determine this) we would like to discuss those options.
Vicinity of Lenape Drive in Berwyn
We have a 500sqft crawlspace which is a little bit damp. We think it needs a dehumidifier to make sure we won't have any mold issues, but the space is very cramped and I don't want to have to go there daily to empty buckets of water. Is this something you can come to have a look at and quote us for a system. Thank you! Olivier

Stone home; 100 yrs old; seepage at foundation wall joint; thin foundation about 3 inches? recently parged stone walls. Evaluation for waterguard or flowguard?
Vicinity of Argyle Road in Berwyn
I have a ~40 year old home with a cement block foundation. The basement has previously been treated for water - and has some sort of coating on the walls as well as two sump pumps. The basement is unfinished and dry (no musty odor at all) with one exception. The northern wall of the basement shows water penetration with what looks to be staining against the wall and moisture on the blocks - sometimes there is moisture at the base of the wall as well after it rains. I would like the source of the problem fixed. Also, we have some water damage in our garage as well - do you do that type of work as well?
Vicinity of Nathan Hale in Berwyn
I have a stone foundation that seeps moisture causing basement and garage walls to deteriorate, mold and crack.
Vicinity of Leopard Road in Berwyn
