"We used A&A to install a complete pressure relief system, new sump pump and back-up battery. They also located and repaired 3 cracks in our foundation. Very thankful for how well they handled this job — along with handling my emotions. Our house is old and with old houses comes problems. They handled all of it very professionally."

"I called Alan after living with a wet basement for over a year. I dreaded every rain knowing that water was entering through 2 window-to-floor cracks. Jason arrived and professionally evaluated and repaired both cracks. 3 days later after a heavy rain I was happy to find a perfectly dry basement. I wholeheartedly recommend A&A."

"I would get water in my basement every spring and had enough. A&A was prompt — got my job done within a week and a half of my phone call. Allen and the team were great. They came on time and finished when they said they would. They respected my wishes of protecting my patio. Very reasonably priced and would recommend to anyone."

Got Questions?

Frequently Asked Questions

Do interior basement waterproofing systems work?

Yes. Interior basement waterproofing systems relieve hydrostatic pressure and collect groundwater before it reaches your basement floor, helping keep your basement dry year-round.

What causes basement flooding?

Heavy rain that raises the water table, hydrostatic pressure, foundation cracks, poor drainage, and failing sump pumps are among the most common causes of basement flooding.

How long do sump pumps last?

Most sump pumps last between 7 and 10 years depending on use and maintenance.

Do foundation cracks always leak?

Not always, but even small cracks can allow water to enter during heavy rain.

Do you offer free estimates?

Yes. We provide free on-site estimates and virtual consultations throughout Connecticut.
