"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!"

"Richie and Vinny are great guys who stand behind their work. I called them about a leak in my basement, which they had fixed a year ago. They came over ASAP, turned out it was a slow leak in hot water heater. I can't recommend them highly enough. Very nice guys. Joe in New Dorp"

"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."

"I am not yet able to determine whether or not the expected results of the basement waterproofing work is satisfactory as I have not had a rainstorm or heavy rain since the basement waterproofing work was performed. I will, however, pay great accolades to Quality 1st customer service, especially to Kyle. I was troubled with the proposal for the job as certain aspects of the language would have left me at an unfair liability should something had gone wrong with the work. I explained this issue with Kyle who followed through until the proposal was acceptable to me. The work crew was exceptional in that they were punctual, worked quickly, neatly and were, without question, among the hardest workers ever to have done a construction project for me. The crew was headed by Wilver along with his guys - Manuel and Jose. Again, I will refrain from commenting on the expected results of the work performed until the appropriate circumstances occur. In summary, I would say that Quality 1st demonstrated A1 customer service and the crew that performed my basement work were hard workers with great attitude."

"These guys were excellent from beginning to end! They were prompt and worked for five hours in frigid temperatures to waterproof the back of my house which is stone siding! So far NO WATER has come into the house when it’s raining. They also brought issues that need to be addressed to my attention while doing what I hired them to do. Very good company to do what I needed done for many years! Glad I have them now!"

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"Headly was very knowledgeable and professional. He was also very honest to tell me that the issue was not an emergency as I thought it was. He gave me a lot of information about the water in our basement and advised me to call him if it happens again after a heavy rain. He also checked out and cleaned my gutter while he was there."

Basement Waterproofing questions, answered by experts

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

Home improvement grants are available for various groups, including individuals with very low-income housing, elderly people, older adults, and veterans. These grants can cover a range of needs, from accessibility modifications to addressing critical issues that may affect a resident's health or safety.

A vapor barrier keeps moisture out of the crawl space, while insulation reduces the amount of unconditioned air—and sometimes moisture—that enters the space. Coupling a vapor barrier with insulation can help prevent humidity and related moisture damage in a crawl space while also making your home more energy-efficient. Just be sure to use insulation that won’t get damaged from moisture, like rigid foam board or expanding spray foam insulation.
