"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"

"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."

"Rahat Construction did a foundation repair and waterproofing in our cellar -- the issue had been bugging me for years and Rahat was great from start to finish. The owner, Kazi, did a detailed walkthrough with me, shared his ideas for solving the problem, listened to my concerns and easily adjusted the plan. They agreed to work within a very specific window of dates, and Kazi's crew was on-time every single day. Farhad, who did most of the work, was friendly and focused, and Kazi checked in with me at the site or on the phone almost daily. Their work was excellent, on budget, and they even finished a day early. I'm satisfied and hopeful our basement will finally be dry this summer and stay in great shape for years."

"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."

"I Hired Hi Tech in spring of 2019 for a repair of my backyard cement work. Kami suggested I replace my cement with pavers instead. His price was so fair, that not only did I hire him to replace my backyard cement, but ALSO repair/waterproof my rear wall AND paint my fire escape as well! I'm so pleased to write that ALL the work Hi Tech did was top-notch & their workers were very respectful and cleaned up very well. Any concerns I had during construction was addressed immediately by Kami, which is HUGE in my book after dealing with other contractors that were not up to par. I would recommend Kami and his workers at Hi Tech Contracting & look forward to using them in the future, because their work raised the value of my home. I now have THE BEST looking backyard on my block!"

Basement Waterproofing questions, answered by experts

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

If you set up a dehumidifier, it will usually dry out your wet crawl space within 12 to 24 hours. Once the space is dry, it’s a good idea to take preventative measures to keep it dry. These include installing a French drain or other exterior foundation drainage system, installing a sump pump in the crawl space, and installing a vapor barrier in addition to leaving the dehumidifier running.
