    Customer Testimonial

              i want to thank Matt for coming by and fixing those little holes in our new crawlspace floor covering before they became big holes. I also appreciate the roll of tape he left so we can catch other little tears and holes in the coming years before they too become larger problems. Still love going down there and NOT smelling the earthy damp smell which we used to experience! THANKS!

    Customer Testimonial

              I would like to take this opportunity to extend my contentment and satisfaction towards your team of professionals. Alex introduced me to your company and with Cory's support was able to close the deal for the 3 projects that I have on the go. They, along with your scheduling team, were eager to meet our deadlines. Upon completion of the work on hand, I felt there could have been a little bit more attention paid to details, although I had no concerns to quality given your warranty on the project. Alex was quick to visit and report back to Cory who in turn put me in touch with your production manager. Upon discussing the issues, your Senior Service Tech. was sent to the site where we met. Fitz’s assessment and performance was of a true professional ... recognizing, explaining, addressing and instilling on his assistant important lessons on quality and customer service. From one business owner to another, I would like to congratulate you on your staff and projection of professionalism that I experienced. I would have no problem whatsoever recommending you, your company and more so your associates for a job well done, excellent concepts of customer service and a follow up worthy of your pride as representatives of your company.

    Customer Testimonial

              I am a repeat customer of Clarke Basement Systems. Approximately 14 years ago I had them install a Cleanspace Encapsulation membrane in my cold room. It was great. No more water leakage and musty odours. But after last winter's ice storm, the membrane came loose in one corner of the cold room. I also had 2 tie rod hole foundation water leaks on the other side of my basement. The service technician, Brendan, reattached the membrane to the wall and double-checked the other walls to make sure the membrane was secure. I have to say it looks even better than the 1st day it was installed. He also sealed the tie rod holes. It rained heavily two days later and no water leakage. I found both the sales representative, Ben, and the service technician, Brendan, very professional, friendly and efficient and they took the time to answer all my questions. I would highly recommend this company.

Symptoms of a problem in your crawl space include leaks and standing water, mold or pests, musty odors, and sagging floors and rotting joists. If you've noticed any of these problems in your home, our complete crawl space repair system can help.

  • Vapor barriers: Crawl spaces are naturally porous structures that allow water in through the walls and floor. Our CleanSpace® vapor barrier is the solution to this problem. This durable product allows us to seal off the entire crawl space and eliminate moisture from the outside. We also offer crawl space doors and vents to ensure a completely protected environment.
  • Drainage & sump pumps: As part of our encapsulation system, we install crawl space drainage systems that will move any excess moisture out of the crawl space. Our sump pump systems come with battery backups to ensure your crawl space is protected at all times. These systems will help protect you from leaks due to exterior water and plumbing issues.
  • Thermal insulation: The crawl space is a common cause of energy waste in a home. Insulating the crawl space will prevent outside air from causing cold floors during the winter and creating humidity during the summer, helping to reduce your energy costs.
  • Dehumidifiers: Crawl spaces are naturally humid environments, and excess moisture and building products is a recipe for mold growth. Our energy-efficient, self-draining dehumidifiers help eliminate this humidity and prevent mold, mildew, and odors.
  • Structural repairs: If your crawl space has been damaged over time, you may have noticed rotting joists or sagging floors above the crawl space. Our crawl space support jacks are designed to stabilize and support your floors, ensuring you don't have to deal with sagging or bouncy floors.
