"Super seasoned crew with Ryan’s leadership delivered outstanding results with complete demolition of existing “cracked” hillside driveway (about 21ft by 30ft), fully reinforced with rebars and fiber lines to protect against future cracking. They have been doing this for generations and know masonry inside out"

"I hired Dalinghaus Construction to install two push Piers for a freestanding column/wall (bad clay soil causing movement). I meet with Kevin to go over the scope of work and he explained everything in detail. The price was the best I can find. Took one extra day to finish the work, but they did not charge me any additional fees. 3 month later, I had a feeling that the column/wall is moving again and call Kevin. He show up in a few days and show me there is no way that wall is still moving and he was right. They are very good at what they do and customer service is the best. Thank you very much."

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"Jose and Daniel did a fantastic job cutting a hole in my foundation and grinding smooth the edges so I could install a crawl space entry system. They did such a great job I also had them install some straps to keep a crack in the foundation from getting any worse. They were very polite, courteous, and professional. Their price was very fair so I paid them a little extra because they did more than I could have expected. I was so impressed with these quality young men that I will probably use them again to build a new block wall and pour a cement walkway."

Foundation Repair FAQs, answered by experts

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

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.

Most building departments will require that a certified and licensed foundation repair professional or a structural engineer pull permits for foundation repair, so homeowners usually cannot pull them themselves. This helps ensure that an experienced professional completes all structural work on your home. Minor repairs that are technically DIYable often won’t require permits, but it’s still a good idea to hire a professional to carry out foundation repairs.

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.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.
