"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 own discount cesspool and drain inc, ive been using Mike for over 10 years! His work is always perfect. He gives me and many new home owners the more resonable prices ever! Mike always comes on time and gives me a free in person estimate. If his price is higher than other contractors he beats the other price quoted by $500 every time. One of my favorite parts about this conpany is that they are family owned and operated. I highly recommend thid company to anyone looking for beautiful work, foundations, waterproofing, Ashphault work, brick and masnary work!! Thanks again Mike and Jim!!! -Dom Motta, president of Discount Cesspool and Drain Inc"

"Alex was amazing!! We had a crack in our foundation that another company attempted to repair numerous times. We were fortunate enough to hear about ProSeal and I am happy to report not only did Alex repair the crack to near perfection but the work was done timely, neatly and his customer service skills are top notch. I would HIGHLY recommend ProSeal for all of your foundation needs."

"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Mount Sinai, NY

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
