Before getting the job done, my basement would flood from even moderate rain, sometimes more than once in a bad week. After the treatment, which took only a few hours, i have not had a single flooding issue since. i used to keep a dehumidifier running constantly just to keep the basement at 45% humidity on dry days; now it'll get below 35% if i let it. we have had severe rain since the treatment and not a drop of water penetration; can't recommend it enough.

George did an exceptional job without recommending unnecessary costly excavations and an unneeded sump pump. His two Commercial Grade Hydraulic Cements process did the trick. My basement leak has been resolved! He guarantees his work. I would recommend New York Waterproofing without reservation!!

GEORGE came twice : 7 years ago and recently regarding another area leaking water. Our house is 100 years old. Since they Waterproofed our home, we have had no water at all. Their pricing was essentially less than half of any other estimate: and ethical.

AFFORDABLE BASEMENT WATERPROOFING WITH A LIFETIME GUARANTEE! My basement walls had 3 cracks in them. They leaked water into the basement when we had heavy rains. To fix these cracks I called in top rated waterproofing companies for their estimates to do their repair work. I found these companies to be very expensive and give minimum time on their warranty's for their work, for the money you have to pay them! Then I found New York Waterproofing Inc. and owner George Carpozi III, George has been in the basement waterproofing business for many years and knows how to fix any type of basement water problem. He has waterproofed residential as well as commercial basements, fresh and ocean salt water problems, leaking basement walls, windows, joints, and water coming up through the basement floor. George can stop the leaks! He has his own system to do this without digging up outside your property! He is so sure he can fix your leak George gives a WRITTEN LIFETIME GUARANTEE on the work he has done for you. Who else does that? I hired George to repair my basement cracks, George and his crew came to my home the Sunday before the NY area had days of RECORD RAINFALLS last week. With all the rain we had, none of the cracks George repaired leaked! The pice I paid New York Waterproofing Inc, and with a written lifetime guarantee on the repairs they made, was about HALF the cost of the lowest estimate I received from the other waterproofing companies I called in! If you have any type of basement water problem, my recommendation is to call and get estimates, but DO NOT SIGN anything, until you call George Carpozi III, and New York Waterproofing Inc. You owe it to yourself, and your pocket! I don't know of any other basement waterproofing company who will give you a written lifetime guarantee on their work. I wish all with wet basements the best, and a happy dry basement to come as well, now go make that call!

We had a need for waterproofing in our basement. Mr. George and his wife came, gave us an estimate and kept their promise on getting the job done on time and efficiently. I will call them again, if the need arises.

The basement leak was completely repaired. The price was better than most others. Some others wanted to do unnecessary work and charge exorbitant prices. George really knows his stuff. His work is exemplary. He is honest and meticulous in his work. I highly recommend him.
