"Mid-State Basement Systems came highly recommended by a good friend from Buffalo, NY and they did not disappoint. From start to finish they were very professional yet personable. Larry & Phil in the initial stages of the basement inspection and a reasonable quote. Silvino and his team who done the actual work was incredible, done with absolute excellence. They were here when they said they would be and finished the job a day ahead of schedule. I am thoroughly pleased with this company, first class. I highly recommend them if you need work done on your basement.******"

"Went above and beyond what was required of them. I am 64 years old and live alone and he has been here twice and his men have been here once working. I had problems with a pipe leaking under my home and he sat down at my kitchen table with his laptop and hunted a repair man for me call them up himself got quotes and set up an appointment that he absolutely did not have to do to help me out because I didn't know what to do or who to call. He has come and talk to me trying to help me get my issues fixed and if it was something they couldn't do, help me find other people that would. They set up my dehumidifier, blocked off vents and went above the job of what they were required to do to help me out. He has sent me text messages after the jobs to check and see if I needed anything. I would highly recommend the company to do any work.He has truly worked with me to get things and problems taking care of that being a 64-year-old female alone that could not have done on her own. Thank you"

"Stay Dry Waterproofing did some crawlspace work for me. Some of the interior walls were separating from the ceiling, due to a soil expansion problem, so they installed foundation support beams which fixed the problem. They also cleaned/fumagated the crawlspace because they found some fungus/mold. Lastly, they installed an interior perimeter drain system that they connected to the existing waterpump basin. I am absolutely satisfied with all the work! The crew did a great job! I spoke to the crew lead a couple times during the project and he took the time to explain, in detail, everything they were doing and how it was going...he was very informative. It made me confident they were on top of things. Mark Menton (Company President) did the initial inspection which led to work being done. He took photos to show his findings and went over everything in detail and provided me with different options to solve the issues. He was easy to work with and a true professional. After we agreed on the best approach to address the problems he provided an itemized cost list for the project. The cost was very reasonable and very competitive to other estimates I had done. I went with Stay Dry Waterproofing because of their high ratings on their reviews and Mark's professionalism...I'm glad I did. I highly recommend them!"

"ErieHome waterproofed my basement. The crew was polite, kind, and came in, did an excellent job in 3 days by digging a trench on the inside of the basement, removing the dirt from the bottom of the foundation, installed corrugated tubing, rock and then cement. They also installed a Humidex airpurifier and new sump pump with a backup pump. They cleaned up afterward. Any questions I had were answered in a respectful manor. I now have peace of mind knowing that I no longer have to monitor weather forecasts for rain or have to clean up anymore incoming water. The system is warranted for the life of the house and included within the price, which increased the value of my home."

"Masonry is an art and skill that is just timeless. And the guys at SF Restoration are masters at this craft. We have a 98 year old home with an all brick exterior that had never been tuckpointed or power washed. Jason and Billy came out and powerwashed it first and they were able to get the original brick color back. Then our 3 main gentlemen: Justin, Nigel, and Rylan did the tuckpointing. They did an amazing job! I can't say enough about these guys. Plus they were very friendly and professional. If you need tuckpointing, etc done on your house, hire SF Restoration! They are the best!"

Foundation Repair FAQs, answered by experts

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.

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.

Mudjacking is usually reserved for light-duty slabs, like patios, driveways, and sidewalks. However, it can be an effective way to lift garage slabs and concrete around the perimeter of the home, which could harm your foundation if it’s not done properly. The risk of damage is why having a professional mudjacking company carry out the work is important. This type of slab or foundation repair is relatively inexpensive, especially if you consider that a DIY job requires that you pay to rent the necessary equipment.

If you don’t have any access to or knowledge of any area underneath your home, chances are it’s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it’s just a few inches tall, it’s likely a slab. If it’s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.
