"Working with Groundworks was wonderful from start to finish. It began with their sales team, Rich G, ensuring my old, quirky home had a customized and thorough solution, phased out to make the job more approachable. Rich took the time to understand my goals for the project and the nuances of my house even though that took significant time and multiple trips to my home. The installation crew (Jose N., Phil S., Diego A.) was professional, prompt and answered ALL of my questions. Their communication kept me informed every step of the way! When the job was completed, it looked like they had never been here - the yard and landscaping look untouched. I would definitely recommend Groundworks for anyone who needs to have their foundation worked on!"

Foundation Repair questions, answered by experts

Yes. Foundation walls are always load-bearing.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

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.”

Yes, you can replace a cinder block foundation. If a block foundation is too severely damaged to repair cracks and other issues, replacing the entire foundation is a viable option. The job will require a professional and can take between one to seven days on average to complete, depending on how complex the problem is.

Yes, you can live with a cracked foundation—in fact, most people do. Virtually all foundations crack from normal settlement, and while settling cracks benefit from sealing to prevent water and moisture intrusion, most aren’t an issue. If you have structural cracks in your foundation, it might be safe to live in your home for some time, but you should address them immediately to prevent structure collapse and major property damage.
