"⭐⭐⭐⭐⭐ We had Adirondack Basement Systems come to our home to lift our foundation, and we could not have been happier with the experience. Mikey, the foreman, and Justin, the installer, were absolutely fabulous from start to finish. Both were professional, friendly, knowledgeable, and incredibly efficient. They took the time to make sure the job was done right, kept us informed throughout the process, and made what could have been a stressful home repair feel completely manageable. It is so refreshing to have a crew come into your home who clearly takes pride in their work and also genuinely cares about the customer experience. Mikey and Justin represented Adirondack Basement Systems exceptionally well. We would absolutely recommend both of them, as well as Adirondack Basement Systems, to anyone needing foundation or basement work. Five stars all around. Thank you, Mikey and Justin, for such a positive experience!"

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."

"This was a very involved plaster repair and remediation job, in a very old house. Grady is the only person (or company) who was willing to take on the job and drive all the way from Pennsylvania to our home in Northern Virginia. There are very few people who do this kind of work anymore (we really searched) and he is an expert in his field. We needed to work around his schedule, because he is in demand in the tri-state area, so it took awhile to schedule the work to begin... but it was worth it."

"I have nothing but great things to say about Serena and her crew. Serena is very knowledgable about her craft, is prompt, friendly, and always willing to answer any question you may have. Staats Masonry does exceptional work - our foundation looks brand new, and our patio is beautiful. Was a great experience from start to finish and I wouldn't hesitate to hire them again! :) In fact, I wish I could call them for all of my home projects!"

"A really great company to work with. Cheaper than the competition and excellent work. We used Aidan and his team to repoint our large garden patio which had been badly done two years ago by another company. Work was done perfectly and we are very happy. We also asked them to do a repair of our entry hall and it was the best it had ever been done. So thank you to Sunnyside Masonry. Paulette Meltzer , New York City, NY"

Foundation Repair questions, answered by experts

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.

Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor who installs concrete patios to inspect the damage and determine how to fix it.

The actual foundation repair costs will depend on the extent of the damage, how many blocks you need, labor costs, and material costs. As an estimate, the average repair costs for a cinder block foundation fall between $350 and $25,000. Because the range is so large, it’s important to call a professional foundation repair company and have them assess the damage and estimate the repair costs.

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.

Minor slab leaks normally take around three hours to access and fix, provided the leak is in an accessible location. However, a more extensive leak or a leak in a hard-to-reach location can take several days to fix, depending on the resulting damage. You might also want to consider the timeline for the build-back if the leak damages building materials like flooring or cabinets, which can take several weeks, including delivery of the materials.
