"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 used this company first to install a dehumidifier and then a sump pump. Prices were reasonable and payment plan option available. My basement is now fully waterproof. The excellent customer service is polite and responds in a reasonable time. Awesome company!!!"

"Rahat Construction did an amazing job repairing my basement and waterproofing the exterior of my house after Hurricane Ida. They regraded the cement, replaced the basement doors, re-fortified and repainted the damaged basement walls and replaced the badly cracked cement on my sidewalk. They are highly responsive, they work very quickly and carefully, and above all, they care about their customers—always taking time to explain decisions and new issues as they arise. This is the second time I’ve worked with them, and I would hire them again in a heartbeat."

"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."

"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

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

To maintain an outdoor structure, perform regular inspections for damage, leaks, and weak joints. Clean the structure regularly, treat or repaint wood surfaces for weather resistance, and reinforce any weak joints to prevent deterioration and ensure its longevity.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

In perfect conditions—meaning, no overexposure to the elements without roofing material on top of it—an ice and water shield can last for decades. In fact, many come with a limited lifetime warranty because they should last for a long time. If, however, the membrane is exposed to the elements during building or if there is a delay in installing the roofing material, it might only last up to 180 days if exposed to the elements. The key is to make it a layer of protection and then protect that layer by installing the roofing.
