"I highly recommend Titan Foundation Repair. I had gotten multiple inspections/quotes from bigger companies who were wanting to do unnecessary expensive work in my crawlspace. Jon identified the water issue I was having in my foundation and gave knowledgeable explanations. The work done was priced fairly and well done! I will be using Titan Foundation repair again for future projects."

"I am recommending inspector Lucas and Groundworks for the work they DIDN'T perform! They came out and did a complete inspection and told me the crack in my foundation wall does not need repairing unless it progresses further. One of my fears in hiring a company off Anti without a personal recommendation and about a topic I'm not familiar with (foundations) is that they might try to tell me I needed repairs when I didn't need them. Lucas was honest, professional, thorough, respectful, and I felt safe around him. Great communication. Texting to set appointment. Texting by both the company and inspector for reminders, when they were on the way, when the arrived."

"Project started out well with great communication to set up initial appointment for quote. The overall job turned out well; but once they won the business, the project was mismanaged and communication was poor. There was an overall lack of supervision on the project. It was scheduled for late November. At the time of scheduling, I asked if job would be negatively affected by snow and cold weather and if I should wait to schedule until Spring the following year. I was assured that winter weather would not cause a problem. Luckily, the concrete was poured prior to several snow storms, but the concrete was not sealed until Spring the following year. The project entailed replacing all sidewalks, a driveway and building a raised patio. The patio measurements were incorrect twice. The second incorrect measurement led to my underground sprinkler line being cut. My sprinkler line was also cut in a second location in spite my pointing out where the underground sprinkler lines crossed under the concrete. Hoses were dragged through my garden with no regard for above ground misters. Several were snapped off. The repair bill when sprinkler system was turned back on in Spring was high, and Legacy agreed to reimburse me for some of the damages. They never followed through in spite of my calling in to check on reimbursement."

"Thrasher did an excellent job repairing our driveway. They leveled out the entire driveway with amazing precision, and they fixed all the gaps with an attractive sealant that blends beautifully with the concrete. All of the team members I interacted with were professional and polite. I am very pleased with the results and only wish I’d called them sooner."

"Dillan did an awesome job fixing my pergola. He was reliable, showed up when he said he would, and the quality of the work turned out great. Everything feels sturdy and looks way better than before. He paid attention to detail and made sure it was done right. Definitely recommend him if you need someone dependable and skilled."

"It went great! They were awesome. The service was high quality. Adrian was extremely helpful and had great idea of what the final outcome would look like. They were very responsive and efficient. They accidentally messed up part of my back fence when completing the project and Adrian came back personally to complete a repair! I would highly recommend them to others."

Foundation Repair FAQs, answered by experts

If your foundation repair claim gets denied, the first step is to carefully read over your policy and denial letter so you understand the reason for the denial. Then, gather evidence and documents that can support your case and appeal the denial with your insurance company. If your insurer does not eventually honor your claim, you may want to file a complaint with the insurance department in your state. In some cases, it may make sense to work with an attorney and file a lawsuit.

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

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.

Yes, thicker concrete is less likely to crack. The thicker the concrete is, the less susceptible it is to extreme changes in weather conditions that often cause concrete to crack or chip. If you’re unable to install a thicker concrete driveway for any reason, you can also ask your professional to install more rebar or wire mesh to provide greater strength and better resilience to damage.

Regular inspections, proper drainage management, and ensuring soil stability help prevent future settlement issues.
