Get matched with top concrete foundation raise pros in Great Neck, NY

"We couldnâ t be happier with the job that Austin did spraying foam to insulate our basementâ s rim joists (where the top of the foundation meets the wood framing). He measured the rate of air exchange before and after, and it was reduced from more than 10 times an hour to 5.6 times, a significant reduction that will result in future energy savings. Weâ re just sorry we didnâ t do this sooner. Zavza Sealâ s pricing was competitive with that of two others. Austin also identified and measured another source of wasted energy that we may address in the future."

"I had a crack in my foundation that needed to get repaired quickly. They did a fantastic job and were a pleasure to deal with. I recommend them for anyone that’s in the same position that I was!"

"Nothing but good things to say about their work and their workers. Job was done on time and on schedule despite some unexpected “issues” with our neighbors, which they handled with the utmost professionalism. They were very responsive to concerns raised during the job and managed to address some small additional tasks that were uncovered and not part of the initial proposal at no additional cost. Needless to say, I am very pleased."

"LI Waterproofing had done extensive work in my basement for the previous owner, so I opted to give them a try myself to resolve new problems that had not been previously addressed. John and his men were responsive and professional.  The work was done as expected and in a reasonable amount of time.  The price was right for the scope of the work requested.  Hand digging was required to expose the foundation outside.  I opted to remove the plants in my garden bed myself before the work was done.  I'm glad I did so. The men worked around the one larger hydrangea I did not move, and it was pretty roughed up during the process.  (I cut back the broken branches that were covered with tar, and I think it will be OK.)  We have had one good rain since the work was done, and the repaired areas in the basement show no signs of dampness.  So I am hopeful.  My sole criticism of the work is that clean-up could have been done better.  Gravel used to fill the window well was spilled into the adjacent garden bed on top of plants.  I spent about 2 hours sorting that out and sweeping the porch and basement where dirt and cement were left.

"Nick and team were extremely helpful, informative, responsive and did exactly what they said they were going to do (and even better when they said they were going to do it). Nick was very reachable via email and was more than willing to help. I hope to never need a foundation expert again, but if I do I know that I would definitely have them do the work."

"Started when promised. Excavation took longer than planned. New floor was laid in good time. Attentive to requests."
