If you want to hire a company like the three stooges hire this guy. Charged me 3000$ to fix a leak in my basement wall, which is still leaking. He guaranteed his work but it has been a month and he has not responded to my texts to fix problem. Did not put up plastic or sheets to contain cement dust. No one wore masks while jackhammering in basement. He did not have the proper tools for job and had borrowed some of mine. A lot of waiting around was done so his wife could go to store and buy the things he needed , like hydraulic cement and mixer. He said he built 700,000$ dollar homes but had no idea how to put a door saddle in, I did it myself while his crew stood around and looked. Tells you he will be there at 9:00 and does not come till a few hours later. Do yourself a favor and go buy some hydraulic cement at Home Depot and do the job yourself. I asked for a written receipt and he just sent a text saying paid 3000. He is a big scammer. Whatever you do DO?NT HIRE HIM
Response from New York Waterproofing
"1. Claim: "If you want to hire a company like the three stooges hire this guy." Response: You didn’t hire a "Three Stooges" operation—you begged a master contractor with decades of experience to save you from $7,000+ estimates you couldn’t afford. We discounted our rate to $3,000 out of goodwill, and this slanderous review is how you show your gratitude. 2. Claim: "Charged me 3000$ to fix a leak in my basement wall, which is still leaking..." Response: The major water intrusion where water poured in around your door was completely sealed by jackhammering an area 37" wide by 12" deep, plus another section 3' by 2' down a foot below grade. The main area is dry. You contacted us about a minor, pedestrian window leak covered under guarantee. When offered service under our 30-business-day warranty policy, you refused access due to your vacation, then posted this review after only 14 days. Your derogatory, racist remarks about our Latino crew will not be tolerated. 3. Claim: "Didn’t put up plastic or sheets to contain cement dust..." Response: Heavy dust is standard when jackhammering concrete below grade. We prepare work areas based on actual structural needs, not the micromanagement of an amateur. 4. Claim: "He didn’t have the proper tools for job and had borrowed some of mine." Response: We are waterproofers, not handymen. Replacing your rigged, falling-apart DIY door saddle was never in the contract—we attempted it purely as a favor. Lacking one niche tool for your haphazard DIY rig doesn't mean we lack equipment; it means we went out of our way to fix your pre-existing mess. 5. Claim: "A lot of waiting around was done so his wife could go to store..." Response: My wife is an equal partner managing critical site logistics. Delivering fresh commercial hydraulic cement keeps field operations running seamlessly. Attacking a businesswoman running supply logistics reveals your prejudice against women in leadership. 6. Claim: "He said he built 700,000$ dollar homes but had no idea how to put a door saddle in..." Response: I never said $700,000. Due to your low IQ and inability to listen, you misinterpreted what was said. I stated my average build is over 7,200 sq. ft.—multi-million-dollar estates. We completed this massive waterproofing job in just 7 hours after waiting around for you to decide to move forward. 7. Claim: "Tells you he’ll be there at 9:00 and doesn’t come till a few hours later." Response: Material logistics fluctuate daily on active sites. Arriving on-site and solving your severe flooding in 7 flat hours is what matters. 8. Claim: "Do yourself a favor and go buy some hydraulic cement at Home Depot..." Response: We are an international firm endorsed across three continents—Europe, the Middle East, and North America—backed by merchant engineers, operating since 1989 on $380M+ estates with zero complaints. If Home Depot cement solved structural water intrusion, you wouldn't have called us in desperation. 9. Claim: "I asked for a written receipt and he just sent a text... He’s a big liar" Response: You received immediate digital payment confirmation, which is legally valid in any court of law. Calling a globally recognized contractor who saved you thousands a "scammer" is absurd. Your toxic, racist "Karen" behavior tells future contractors everything they need to know."

Please don't hire this guy, He is a scam artist, he lies, and does bad sloppy work He also go by the name George Carpozi, neither companies have a license. He damaged my house, windows and walls. Floors are worse then before, Walls, put them back together with no insulation and cracks hidden behind baseboards. New flooring in bedroom so poorly installed needs to be redone. Minimal drop cloths used. DUST EVERYWHERE!!! Greasy handprints left on walls. Bedroom had to be painted. My house was trashed and he ruined my Christmas/Seasonal tree, had to be thrown out. He barely supervises his unqualified employees. Watch out for this character, he is a scammer and should be in jail. Definitely look him up with Consumer Affairs and Better Business Bureau. HE IS UNLICENSED. Takes all money in cash upfront, and takes any criticism or suggestions as personal attacks on his character. Don't be fooled by his initial meeting with you when he is

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!

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.

George did the waterproofing in my basement, it was a good job
Response from New York Waterproofing
"This man had black mold, water infiltration, tree roots, and soil entering his basement. On the first visit, we removed the black mold and waterproofed his home on the first visit. He became upset that we did not return to install the drywall we removed that had black mold on it immediately; we incessantly stated he needed to wait for a few heavy rains before we installed the drywall to make sure the area was indeed dry. We returned when that was established; he was happy. We did the job $4,000 less than the next lowest bid."

George is the best. Did everything he said he would. Very professional. A job well done. I’d hire him back without a doubt.
Response from New York Waterproofing
"Joe; your house was a tough one; for the water entering the basement was from a high water table; and it was entering through the back wall. It was stubborn, but through our proprietary processes and methods; we conquered the problem, though we worked into the night. Thank you for the snacks and coffee!"
