"I needed stucco repair work on an old chimney (and other spots). Grady was meticulous and thoughtful on what approaches and materials would work. Throughout the project they allocated sufficient time for each treatment to cure and inspected the work before proceeding to the next step. Grady started the project with no money down and only required ongoing payments for materials until the project was well underway. The final payment was due only after they did a final inspection. Total project cost was also below other bids."

"Ryan proved to be a professional in every way. His gave a fair and what I felt was an on-point quote and was here when he said he would be. My front porch was cracked, caving in and separating from the house, so the present slab had to be removed and the railings around the porch as well. He was through and completely in tune with what we discussed. The whole job was done and complete in 5 days- that included curing and set up time with cement drying. Yes, I would use Ryan again and we are already discussing the next project. I found Ryan on Angi website and I am very happy he was available to do the project. Thank you Ryan!!!!"

Foundation Repair FAQs, answered by experts

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Detailed inspections and tests to determine the extent and cause.

While a contractor is on-site repairing your concrete steps, you can have them inspect other concrete surfaces for minor damage. They may be able to fix cracks in your driveway or garage floor during the same visit. You can also ask them to check your home's foundation for minor issues they can address. However, general concrete repair experts typically cannot handle larger jobs, like leveling a sunken foundation. For major structural projects, you will need to hire a structural engineer.

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

Barring extreme home foundation problems, most horizontal foundation cracks are fixable using one or more methods. Most of the repair methods require professional expertise to accomplish, and include plate anchors, steel reinforcement, soil anchors, reconstruction, or carbon fiber strip applications. Contacting a professional to diagnose the problem early can minimize repair expenses.
