I had a garage that I demoed what was left with the foundation footings I just could not believe how much he ripped that up four loads in the truck graded it out he did a beautiful job.

"Zavza Seal is an excellent business! We had a leak in our basement which was attributed to a problem with the foundation. The project manager responded promptly, clearly outlined the specifics of the problem as well as the plan for the repair. He patiently answered all of our questions and concerns. The estimate was fair and reasonable. The crew also arrived promptly and went above and beyond to assure the job is well done. We are extremely satisfied with the job. Zavza Seal is truly an outstanding group of professionals that I highly recommend."

"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."

"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!"

Foundation Repair questions, answered by experts

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

It’s crucial to hire a foundation company that’s professional, experienced, and reliable, starting by choosing local experts with at least five to ten years of experience with your type of project. Local foundation companies will understand the soil and weather conditions in your area and can carry out the best solution based on your property characteristics. You should ask for a list of customer references, read through online reviews, and check for customer complaints and unresolved issues filed with the Better Business Bureau (BBB) before hiring.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.
