Introduction
With over 35 years of unmatched expertise, New York Waterproofing, Inc. has solidified its reputation as the gold standard in basement waterproofing. Since our founding in 1988, we have helped thousands of homeowners and businesses across the country—and around the world—achieve dry, safe, and structurally sound basements. Our cutting-edge technology and industry-leading methods make us the only company in the U.S. capable of permanently stopping hydrostatic pressure without pumps, drains, or exterior excavation. We take immense pride in delivering the most affordable and effective waterproofing solutions in the industry. Our services start at just $1,299—a fraction of the cost of traditional waterproofing methods—without compromising quality. We’re so confident in our expertise that we offer a price-match guarantee: if you find a verifiable lower price for true waterproofing, we’ll do the job for free. No competitor can match our results, and none are willing to make this promise. Unlike outdated and costly systems like French drains and sump pumps, our revolutionary approach targets the root cause of water infiltration, ensuring permanent results. In just three hours, we can transform a leaky, damp basement into a dry, odor-free space—without disturbing your property or requiring unsightly external excavation. Our proprietary sealed membrane technology withstands pressures over 12,000 PSI, creating an impenetrable barrier against water intrusion. Designed to last a lifetime, this advanced method outperforms every other system on the market. In fact, our technology is so effective that it is USDA-approved for use in food treatment facilities, completely free of harmful VOCs, and environmentally safe. We believe that peace of mind starts with trust, which is why every project is personally overseen by our expert proprietor, George. With decades of hands-on experience, George ensures that each job is completed with unwavering precision and care. When you hire New York Waterproofing, Inc., you’re not just getting a service—you’re investing in permanent protection for your home and family. Every job is backed by our Certificate of Guarantee, meaning if water ever re-enters a treated area, we’ll fix it at no cost to you—including labor and materials. Our warranty is the strongest in the industry, giving you the confidence that your home will remain dry for a lifetime.

After years of vacuuming up my basement of water from heavy rains I finally had enough. I found multiple companies on google and none of them beat the price that New York Waterproofing Gave me. I hired them for the Job, which may have been one of the best decisions I've made in Years. They came in when the water was actively coming in through my wall and to my surprise they stopped the water right before my eyes. I highly recommend them.

George and team came and did work on basement window wells. Sealed and waterproofed. Very communicative, thorough on the job. Professional and reasonable on project cost.

Very unprofessional in how they deal with potential customers. Extremely rude and harass you when you don’t reply right away by repeatedly texting, then calling and leaving 3 minutes long messages about how they are superior to anyone else and how I’ve “been warned”. Terrible customer service. Wouldn’t hire them sheerly on how disgusting they are to people looking to have work done. Stay away!
