"Rock Hard Concrete was prompt in coming out to give us a quote to repair our front concrete porch and small side walk in front of it. They had the best price and found away to salvage our railings which no one else was able to do. The team did a great job repairing the porch and the surrounding area. They were efficient and cleaned up the work area very nicely."

"I live in Great Kills, Staten Island, and I had Tri Stone come out to repair my red brick front steps and the limestone liners. They repointed the brickwork, repaired and secured the liners, and really brought the whole step back to life. The difference is brilliant. Everything looks clean, solid and properly finished again. The guys were great to deal with and did exactly what they said they were going to do. Really appreciate the work they put into it and I would definitely recommend Tri Stone to anyone needing masonry work done."

"This is a review of the *experience* we had with Quality. We had the basement waterproofed, so we won't really know how good the job is until a big rainstorm! So this is just the experience we had before and during the job. We reached out to Quality based on the Angie's List reviews, and were convinced by the visit from Greg. He was so knowledgeable about the water problems, and pointed out the years of experience the company has. Also, we weren't looking for a bargain, we were looking for a dry basement, and Greg was very straightforward about all the costs. Now we haven't had a rainstorm yet, so we still don't know the most important thing about the job! But Victor and his crew were fantastic. They knew what they were supposed to do when they got here, and did the whole job-- as quietly as possible-- in less than 4 hours. They were pleasant to have in the house. They left the place clean. So big thanks to all at Quality. P S: Will update when there's a big rainstorm."

"I bought a house in 2021 that had significant water damage leaking through the walls onto the concrete floor in the basement. After researching multiple companies around the area, I reached out to Basement Gurus. Ashley, Boni, Josh, and owner of the company Dan Kelly, all went above and beyond to make sure that there would be no more water damage. They installed a French drain, vapor barriers, and more. The owner Dan Kelly personally came out to make sure that the work got done correctly. This company is the best around, you won't be disappointed."

"They responded quickly. Presented a clear plan to keep our basement dry. They did the work as promised in a timely fashion, and persevered through obstacles (cramped conditions and thick reinforced concrete to hammer through). I'm satisfied."

"JRH Paving repaved an existing driveway that was first paved in 2003 by another firm. The previous firm did an adequate job but created a water problem for a building that was down hill from our house. JRH gave me an estimate to repave the driveway, fix the water problem which wasn’t easy, and to do a little more paving than was originally there. The job was more than 10,000 square feet. They showed up on time, removed the surface of the original paving, fixed the water issue, re-paved the entire driveway, and did it in one day! The owner operated equipment and was on site all day, the equipment was well maintained, and his people were professional, office personnel to truck driver. I would recommend JRH."

"I recently moved into a single family residence in Passaic County which needed a relatively small job of concrete repair around the pool area. The owner responded to my inquiry, came out, inspected the project and provided a very fair price estimate on the spot. I selected this pro after getting 4 other quotes, job was completed as promised, neat work and clean up was impeccable. Try Top Rank for any of your construction needs, you will be very pleased with their work. Sincerely VP"

Concrete Repair FAQs, answered by experts

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Yes, slab foundations can sink just like any other foundation type. Floating slabs are the most prone to differential settlement and foundation sinking because they sit directly on the surface of the earth. Slab foundations that have footings—including slab-on-grade foundations and monolithic slab foundations—get additional support from soil further down and are less likely to sink over time, especially under larger, heavier structures.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.
