"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!"

"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!"

"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."

"Great! John, the owner was super helpful and nice on the phone. Eased all our concerns. The crew, Phil and Tim, showed up right on time and were able to locate the service caps in the lawn in 10 minutes. They showed me clearly how full the tanks were and clearly explained the problem and the solution. The prices quoted were very fair and there were no surprises. It took around 90 minutes. The job was all done outdoors and when they left you would never know it was done. Very neat and professional. The odors, etc we had were gone and we noticed the drains all flowing more freely. Exactly as they said. So glad we had this done before it became a serious and ugly problem inside the house. We highly recommend Priority Cesspool Sewer and Drain. Thank you!"

"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."

Basement Waterproofing FAQs, answered by experts

The process might take a few days to a week, depending on the method chosen, area size, and weather conditions. Some solutions, like simple interior sealants, may require less time.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

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. 

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
