"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."

"Front step Bluestone concrete was cracked and the concrete underneath was crumbling. Salt and elements accelerated the problem this winter. Called on a Saturday afternoon, Cleiton was there within an hour! By evening, an emailed estimate arrived. Job commenced, Cleiton was there every day, with an additional helper. Cleaned up EVERY night, the job site was cordoned off for safety and Cleiton communicated adjustments that were necessary as the project ended up being a bit more difficult than we thought. (The underlying concrete was crumbling and had to be re-poured.) Overall, EXCELLENT job and though it was a bit more than estimated, the price was fair for the work done and done beautifully."

"Roca and his team were very professional and did a thorough job on repaving my driveway and repairing our front sidewalk. The team delivered as promised and on schedule. In addition they worked quite fast although it was clear they paid attention to the important details. I would surely hire them again and am quite satisfied with the work they did ."
