"Several months ago, I noticed that doors in my house were no longer closing and latching. Specifically, my front door no longer locked completely. Once I got it fully locked I could no longer open my front door anymore, so I knew I had foundation issues. I called Bay Area Underpinning to come look at my foundation and do some measurements. We discovered that my front living room was sinking approximately one and a half to 2 inches. The crew, Lance Sladek, Jake Hall, and Eddie Shaw, crawled under my house and dug 30 to 40 foot holes in the ground to install piers that would lift my foundation. These gentlemen worked in very cramped dirty conditions in 90-100° weather. I was extremely happy with their work and their dedication to doing the job correctly. My after the foundation lift, my front door as well as several other doors in my home were able to close and latch again."

"We were in need to Remodel our Bathroom due to leak from the pipe in between two Bathrooms and change out the plumbing of our house from galvanized steel to copper, upgrade drain to ABS pipes. Geico Builders crew had an immediate availability to solve our issues. Mila was assigned to our project as a project manger. The communication of the project manager was outstanding as well as guidance on what has to be purchased for completing our beautiful Bathroom. Once the water leak was discovered and the subfloor damage was assessed. A repair plan was quickly in place for the leak. Plus a plan to restructure and build a stronger subfloor. Overall, Mila and Supervisor Ruiz and their team were very excellent at staying on schedule and completing the project with quality workmanship. Overall we are very happy with our beautiful new bathroom. Our renovation project was completed on time and the new look absolutely met our expectations. Our main expectations/requirements were a regular shower pan, the shower walls and the flooring, all done with quality porcelain tile. Adding a shampoo niche and 2 safety grab bars in the shower area. Plus the bench which I am so happy with. All of these items were installed with attention to detail and with quality workmanship. Thank you Geico Builders for your professionalism and hard work we are truly Happy with everything you had done to our house and looking forward to work with you for our new project which is going to be Kitchen Remodeling by next year."

"I hired Danny to replace four bedroom windows that had been leaking when it rained. From the moment he inspected the windows until the day he finished the project, he displayed professionalism, expertise, and efficiency. He not only made sure the job was done but also made sure it was done right. I appreciated his attention to detail and explanations of what happened, why it happened, and what repairs needed to happen. Danny also respected my home and made sure to always clean and tidy the debris that had been made during the construction. I enjoyed working with Danny and would recommend him to anyone who needs home repairs or improvement."

Foundation Repair FAQs, answered by experts

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.

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

Crumbling concrete steps will affect your ability to drill into the material and affix a sturdy railing. If the damage is primarily cosmetic, you might be able to DIY the repair with a patch kit. If the concrete is badly crumbling, hire a professional who specializes in pouring concrete. The average concrete step repair cost is $500 from a professional, but the extent of the damage will determine your actual cost. The professional may recommend a replacement if the damage is extensive.

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.

Concrete can crack from general wear, improper installation, or in response to uneven support from the soil underneath. Small, thin cracks on the surface of aging concrete are usually a result of normal wear and tear, while cracks on new concrete more likely indicate a problem with installation. Larger cracks or uneven steps can signify a much more severe issue. A concrete contractor should be able to diagnose the cause and repair concrete cracks for you.
