Customers say: Terrific value

"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

"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 have had heavy rainstorms since and no more floods! Glen and the team are so professional and could not be more helpful. They are reasonable and worth every dime! Highly highly recommend!! They go above and beyond."

"Had a backup a few days before and wanted to determine if it was a simple clog or cesspool related. They sent out a tech (Jimmy) the same day. He located both cesspools and walked me through my options. He was honest and patient, answering all my questions along the way."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

"When I am having work done on my home, I want folks that are knowledgeable, reliable, and punctual. I had a REALLY good experience with Zavza Seal. They are an incredibly well-run organization. Before any work is done they provide you with a PDF estimate with photos and detailed descriptions of the work being done. You then receive an invoice (that agrees to that estimate) payable by checking or credit card (via Quick books). Their billing department is separate from their workers, and all workers were supervised by a manager who was also responsible for doing the estimate. From the start of the estimate, I felt taken care of. Dice their admin was incredibly responsive to all my questions, emails, and texts. Jake the manager of the team was incredibly thorough when overseeing my project, and Andersen (who was doing a lot of the project work), was incredibly professional and always took the time to explain to me what they did and what was left to do before they left my home each day. Everyone always showed up on time when they said they would. I had a relatively large project - waterproofing my exterior and then replacing a sinking floor in my porch from old water damage. They tackled outside first to ensure no more water would get into my interior. I was sealed up outside with base create (concrete used for pool settings), and sealant. They addressed every single spot I wanted to be covered, and also sealed up spots I had no idea needed sealing. They worked around my schedule, and it was great that I had a point of contact outside of the day-to-day workers (Dice their admin) that I could reach out to for scheduling, questions, invoicing, etc. I love the fact that these are two separate parts of the business. Each part does its job very well and it makes a great customer experience. My porch floor was a larger project since the beams holding the floor up were rotted and needed strengthening. The floor needed to be ripped up and with that - we went with all new tile. I was talked through every step of the way, and where project costs needed to be increased, it was very transparent and I was always consulted and presented options and reasoning. Every quote for all work done was incredibly reasonable. I never felt gouged or nickeled and dimed. It was always a fair price for the work and materials. I could not ask for better communicators. Before I settled up the final payment I was walked through all the work done, and they understood I wanted to run my water test before paying the balance to ensure all the leaks I was having were settled. This required them to wait 48 hours (for the base to create and sealant to cure) for me to do that, and I never felt pressured, or questioned as to why I wanted to do that. The basement is dry now, and I have peace of mind! This company cares about doing good work, standing by that work, and ensuring the customer is satisfied. Every question/concern I had was addressed and answered. I always try to be a good partner to the contractors I hire (being clear and transparent about what I want done, limits to my schedule/budget, honest assessment of the situation, paying on time when work is done, etc.), and I appreciated that Zavza Seal recognized that, and reciprocated it, not all contractors do. The work done on my home came with a 5-year warranty. I hope that I never have to use it, but I know this team stands by their work, and I am confident I will be taken care of if I have any issues. This is incredibly rare these days, and I will be recommending, and using them in the future! Seriously the best experience I have ever had with a contractor."

Basement Waterproofing FAQs, answered by experts

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Standing water under your house can threaten its structural integrity. If water pools in your crawl space, it can damage the foundation and the structure above ground, causing wood rot, mold, and other problems. If you have a concrete foundation, standing water under your house can also make your foundation slabs crack.

Yes, professional installers use weather-resistant materials to protect the dish and cabling from environmental damage.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.
