Why Waterproof?

Waterproofing your basement is one of the most essential investments homeowners in Connecticut can look into. With the necessary precautions set in place you can transform your basement into livable space, and protect against further damage that could threaten your home.

Common and affected areas in your basement that cause issues:

  • Clogged floor drains
  • Leaking wall or floor cracks
  • Where the wall meets the floor (Cove joint)
  • Leaking basement windows

Waterproofing your basement is one of the smartest ways to enhance your home’s value, protect your investment, and create a safe, usable space for your family. By addressing these common problem areas, you can help ensure long-term protection against water damage and costly repairs.


Don’t let water issues impact your basement’s potential. Contact us today to schedule a consultation and take the first step toward a dry, secure basement!

Recent Work

We went out for quotes on an expansion tank install. A-Team was not only responsive, but they were one of the only contractors to show up for a site walk. And even better, it was the owner that came by. I'd highly recommend them for plumbing work.
