"From start to finish our experience with Foundation Works was top notch. We did contract them to bolt the foundation on our 1921 Spanish Bungalow home and repair some minor foundation cracks in a 1950's addition. Prior to calling Foundation Works we had two other estimates for work, one was in line with the quote provided by Foundation Works and one was higher with a few additions to the work. So I would say their price was in parity with others. Myron did our initial inspection and spent a lot of time crawling around under our home and doing a very detailed inspection. He spent a long time sitting with us afterwards discussing what he discovered and what he recommended. He was very patient with our many questions. When we tried to add some additional work reinforcing what looked like some long term slippage on the peers under the house he carefully informed us of the history of how houses like ours were built and why we did not need to spend more money doing this repair as it wasn't slippage but rather just how it was built. Once we accepted the bid FW was able to start work quickly. They worked cleanly and while they don't clean up every day before going home they also don't leave a bad mess and the work was all in the backyard so a few piles of tools was not a big deal at all and was painless. The team that did our work was professional, friendly, and efficient. When we had questions they were always there to answer. When we had one (very small) issue related to the nails originally used in the 1920s to hold the corner floorboards in which had jumped up a bit due to the installation of blocks needed to support the bolting in a few places, they stopped work, immediately fixed the issue and adjusted how they worked so it didn't happen again. When the work was done you wouldn't even have known they were here. The yard and all entry points to the crawl space were spotless. The Burbank city inspection was a few days later, they handled it completely and we never needed to worry about a thing until they handed us approvals. The back office and payment process was professional, pleasant, and very low touch. I can't recommend this company more highly."

"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"I couldn’t be happier with Amir, I am glad that I found him. I’ve been dealing with many contractors and they all have been unprofessional, dirty, and they slowly neglect the job to work elsewhere, leaving mine incomplete. I’ve had to be on top of them just to get the work done, they would usually show up when it was time to get paid. I had lost faith with all contractors, that is until I found Amir. He is the opposite of what I’ve dealt with, professional, to the point, honest and works cleanly. He recently paved a four garage driveway. He got the job done so quick, that my head still spinning, not only that, when I showed him the respective area, he took the measurements, got on his phone to run some numbers, and made an impromptu quote. We picked the dates and the job got done. No B.S. no chasing after Amir. DONE!!. He is currently working on a historical home for me. I will come back and add additional details about my experience with Amir once the whole job is completed, but, as of right now, I am extremely happy. The work is getting done, and quickly. The foundation work started with in a couple of days after we signed the contract. If this was a different contractor, I can positively say that I would still be waiting for the work to begin. If you want to have a horrible experience, do not hire Amir, because you will only have a good, professional experience. Amazing work Amir."

Foundation Repair FAQs, answered by experts

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

In most cases, yes, homeowners insurance will cover burst pipes, even if they run through your foundation. Not only that, but most home insurance companies will also cover any foundation repair you need done that resulted from the plumbing leak because your insurer will view the leak as an unforeseen and non-preventable issue.

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.

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.

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.
