    DO YOU HAVE WATER LEAKING INTO YOUR BASEMENT AS I DID? I FOUND SOMEONE YOU NEED TO TALK TO!…read more 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 they give a minimum time, on their warranty's for their work, for the money you have to pay them! $3000.-$10,000. for inside repair work with a 2-5 year warranty on their work. If they dig up outside, and make repairs, $20,000.+++ with a 10 year warranty. OUCH! Then I found New York Waterproofing Inc. and owner George Carpozi III, who is also a custom luxury home builder too, on Angies list now called Angi. 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 will be honest, I was very skeptical of Georges promises to me, and I told him so. He emailed me a list of people he had done work for all over NYS, he said call whoever I want and ask them if I stopped their water leaking into their basements! I called 4 people on the list, 3 from Long Island and 1 from upstate NY, ALL said they no longer have water leaking into their basements. One was a commercial property too. George is the real deal! 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 just last week. With all the rain we had, none of the cracks George repaired leaked! The price 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. Even if your basement is not leaking, keep his number just in case. Give it to someone you know who has basement water leaking problems. I wish all with wet basements a better day, and a happy dry basement to come soon as well, now go make that call, George Carpozi III, 631-806-9690, also below is a link to his website. Good luck! https://newyorkwaterproofinginc.com/

    We had a major problem in our basement, so we contacted George at New York Waterproofing. He and…read morehis wife were very professional, human-oriented and kind. They came the day/time they promised and finished the job as promised. I am glad we were able to count on them for our basement's waterproofing needs. I hope to see them again, if the need arises again.

    I had an appointment scheduled with Rainbow Basement Waterproofing for an estimate on 11/1/18. No…read moreone showed up or called to say they weren't coming. I called them an hour after the scheduled appointment and left a voicemail asking if they were still coming. I never received a call back. I would be real weary of using this company.

    These guys were great. I had a leak in my basement whenever it rained hard and first called a major…read morecompany. A salesman came over who didn't do the actual work and gave me a very hefty quote. A friend recommended Rainbow as he used them and said they did a very good job at a fair price. I called but was skeptical. The owner Mike personally showed up to my house and diagnosed the problem, explained what needed to be done and showed me photos of jobs he did with the same problem. He then quoted me half of what the first company did and did the job a couple of weeks later. Mike showed up with his workers the day of the job and explained everything to me as they did the job. They seemed very knowledgeable and obviously have been doing this work for many years. The job was very clean, no corners were cut, and they seemed to enjoy the back breaking work. I hope I never need them again but if I do I would not hesitate to call or recommend them. What was refreshing also was that Mike seemed like a very honest person and his pricing was very good while at the same time not cutting any corners.
