01 โ€” Sump Pump Install & Repair

The Hardest-Working Appliance In Your House

A sump pump is the appliance most homeowners never think about โ€” until it fails, or until they suddenly need one. We install, replace, and repair sump pumps across Connecticut. If your pump is more than 7โ€“10 years old, it's living on borrowed time.

What we install:

  • Primary sump pumps (cast iron, properly sized)
  • Battery backup pumps โ€” for when the power goes out

Signs You May Need A Basement Waterproofing System

  • Musty smell or humidity
  • Water coming through cracks

Interior Basement Waterproofing System

Got a wet basement? You're not alone in Connecticut. Clay soil, granite ledge, and wild rain patterns mean half the basements in this state have a water problem at some point. We've been fixing them for over 50 years.

Our interior basement waterproofing system โ€” the A&A Basement Relief System โ€” uses hydrostatic pressure relief drainage installed inside your basement. Water is absorbed by the system before it ever reaches your floor. It's the same proven system we've installed for over 50 years โ€” backed by a lifetime guarantee.

What's included:

  • Full perimeter or partial interior systems
  • Discharge line routed away from the foundation
  • Clean-up โ€” we leave the basement cleaner than we found it
  • Written lifetime warranty on the system (no fine print)

Signs You May Need Exterior Drainage

  • Basement flooding after heavy rain

  • Water running toward your house
  • Overflowing gutters or downspouts
  • Water collecting near walkways, patios, or garage doors
03 โ€” Exterior Drainage

Stop Water Before It Reaches The House

The best way to keep water out of places you don't want it is to stop it before it gets there. Exterior drainage is the most underrated waterproofing investment a Connecticut homeowner can make.

What we install:

  • French drains around foundations, along driveways, patios, and more
  • Grate drains for garages, patios, and walkways
  • Downspout extensions and underground outflow lines
  • Yard regrading where needed
  • Curtain drains for properties with hillside runoff

Properly installed with quality fabric and stone, these systems last 20+ years.

Two foundation cracks sealed by A&A Basement Waterproofing using polyurethane injection โ€” repaired flat against the basement wall
Signs You May Need Foundation Crack Repair
  • Water entering through wall cracks
  • Cracks getting larger over time
  • White chalky staining on foundation walls
  • Wet spots appearing after heavy rain
04 โ€” Foundation Crack Repair

Slow Seep or Full Geyser โ€” We Seal It

A crack in your foundation can be a slow seep, or it can spray like a hose during a downpour. We've seen cracks fill a basement with 2 inches of water in an afternoon.

We inject polyurethane into the crack under pressure. It fills the crack all the way through the foundation wall โ€” not just on the inside surface.

We can even fix the crack from the outside if you have a finished basement โ€” so we don't have to touch your drywall or trim.

05 โ€” Radon Testing & Mitigation

You Can't See It. You Can't Smell It. You Can Fix It.

Radon is a naturally occurring radioactive gas that seeps up through the soil into Connecticut basements. It's the #2 cause of lung cancer in the United States. The EPA recommends every home be tested โ€” and many parts of Connecticut have elevated radon levels.

If you're already opening up the basement for a waterproofing system or sump pump, it's the perfect time to test for radon. If levels are high, a certified mitigation system vents the gas safely outside.

Radon services are coming soon โ€” we're finalizing our certifications now. Call us and we'll let you know when we're up and running.
