A1- Crack Repair provided the most reliable, professional service I have experienced in a long a time. I had a very stubborn water problem in my basement and tried everything to get the water to stop (two sump pumps). While it was hard to stop the water A1 would not quit on the job. They came back to ensure it was done right (even after I had already paid). You just don't see service like this anymore. It is a pleasure doing business and I would most certainly recommend A1 to a friend.

I wanted you folks to know that I am highly satisfied with the work quality of workmanship in resolving my water problem in my basement.

It rained harder than ever a week ago and a tremendous amount of water could not penetrate the seal.

Thank you much.

Thank you for your visit of your technician today. He was skilled and considerate. He diagnosed the problem was a leak in the vertical junction of the new addition 12 years ago and the old house. I do not know why it was sealed all these years. The new addition did not seal closely to the new addition. He also drilled some holes in the floor in the horizontal junction between the vertical wall and the horizontal floor. He also filled a hole on the concrete on the outside of the addition near the junction of the new and old wall. We will not have a good test of the seal for some time unless the hurricane Sandy comes ashore. I pray that the fix will hold the water back. Thank you again.” Mr. L, M.D.

"Thank you so much for coming to my rescue in a time of need! My basement was flooding, water coming in through the foundation, and I was exhausted from trying to keep up with it. You guys realized the importance of prioritizing me, and put in a Sump pump to save the day. You are the best!" - Joanne Lipsy

"We've used A-1 a couple of times and are always pleased. All the cracks that have been repaired have held up beautifully and we are now enjoying a newly finished basement with no concerns about water due to the cracks!" - Brendan Kenahan

"A couple of weeks ago we had A1 out to do some work on the bulkhead at our home in Woodstock Valley, CT. So far we are extremely pleased with the performance of the injection, I'd say 2 days after the work we had 4 inches of rain in one evening, not a drop came in. I can sleep easier now about the decision we made last month to finish our basement, we love having the extra, dry, living space." - Ron Sanderson
