"Ted showed up on the time and date we scheduled. He assessed my home’s foundation and determined that the level of repair needed did not require his company’s intervention. I was extremely impressed with Ted’s honesty and forthrightness. In a world where homeowners are often faced with costly repairs it was refreshing to deal with Ted and by extension Dalinghaus Construction. If in the future I have need of such services I would not hesitate to call upon Ted and Dalinghaus Construction."

"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."

Really, Ive never had a crawl space and while having one in my first home i did not know what to look for that was in need of repair. Bob did a thorough job looking over it for me and very honestly delivered me feedback. Turns out i am not in a dire need of repairs but when i do, i know who to turn to. Thank you Bob, and GroundWorks for the professionalism"

"Rafael did a fantastic job on my backyard project which included building a beautiful new planter, new concrete patio & Astro turf accents. He dealt with our HOA in a truly professional manner, submitted all plans per their specifications, and design/planned the whole project. Professional, communicated well, kept on schedule, had hard workers with cheerful attitudes & cleaned up the site after every work day. I would highly recommend Rafael for any concrete related project."

Foundation Repair questions, answered by experts

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

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.
