"This is THE company to use. I had an old 1907 wooden house sitting on a decaying brick foundation and needing a sister foundation installed and a complete seismic retrofit. Even during the bidding process, Brad from Alpha was extremely attentive without being assertive. I contacted four other companies although one I eliminated since they charged a fee for inspecting. Alpha was very timely with their bid and flexible when I needed help with the budget. All the way through the process, every single person at Alpha was extraordinarily good at customer relations, returned emails immediately, and stayed in constant contact throughout the entire process. Whenever there was a slight change to the original plan due to permitting or a plumbing adjustment, Alpha was very proactive and made sure everything was communicated clearly and promptly. I have really NEVER worked with a company that had such excellent communication skills. This is really one reason I selected them to do the work and, even though they may not have been the least expensive, it is worth the extra price for this reason alone. And Alpha Structural's work speaks for itself as well. Everything was done precisely and well beyond code, an unbid section of foundation was provided under the front porch without increase to the budget, and all materials used were of the highest quality. The project went on somewhat longer than estimated due to permit changes and a short weather delay but was still finished in a timely way. My home is our family's largest asset and it is a great relief to now know it is sitting on a solid foundation. The entire process from first to last was excellent and I cannot say enough good things about the way Alpha Structural handled the project. From the front office to the boots on the ground: A++"

"Bob Warren was simply terrific, i had a great experience consulting on my crawl space. Really, Ive never had a crawl space and while having one in my first home i did not know what to look for that was in need of repair. Bob did a thorough job looking over it for me and very honestly delivered me feedback. Turns out i am not in a dire need of repairs but when i do, i know who to turn to. Thank you Bob, and GroundWorks for the professionalism"

The owner also stopped by to ensure everything was going well. The results of their work was outstanding."

"I hired Dalinghaus Construction to install two push Piers for a freestanding column/wall (bad clay soil causing movement). I meet with Kevin to go over the scope of work and he explained everything in detail. The price was the best I can find. Took one extra day to finish the work, but they did not charge me any additional fees. 3 month later, I had a feeling that the column/wall is moving again and call Kevin. He show up in a few days and show me there is no way that wall is still moving and he was right. They are very good at what they do and customer service is the best. Thank you very much."

"Our project was one step and a landing on our porch. Approx. 30 sq feet. We had the top layer of tile removed and concrete around the door area chiseled and jack hammered away. They then cut fossil stone for risers and step/landing in large squares as requested. They did put up a moisture barrier at the entrance and calked after grouting the stone. This was done upon the City of Downeys expectations. I believe that wouldn't have been done had I not called the city to come by to clarify the code for this job. So my only complaint is that some workers, actually most don't keep up or research the code. Then when the city does visit you may have to tear down a project and re do it. That can be costly and frustrating. Our porch and step look great. Not sure if the cost to us was cheap, but it is done and looks great."

"The guys at Del Mar Landscaping were great. Conrad, the owner of the company is the best. He is honest, understanding, and willing to work with you. His workers are also great - they always came with a smile and eager to work. They worked round the clock to get as much done as possible each day they came. Now, like all construction type jobs, there were a few things that didn't go as planned but the guys made sure to fix things as best as possible to give me what I envisioned / wanted. Ex. the putting green they installed was a little bumpy around the holes, wasn't as smooth as I'd hope it'd be - they came with a solution and fixed it within a few days of me letting them know. There were even a couple occasions where the plants they planted died a couple of weeks after they put them in and they, without question or hassle, replaced them. They are willing to own up to their mistakes (it happens) and fix things - which is refreshing as not all contractors I've dealt with are like this. I would definitely work with these guys again."

Foundation Repair questions, answered by experts

If your foundation is unfinished, has surface damage, or is just plain unappealing, foundation refacing can be another great way to increase your curb appeal and give your foundation a fresh look. Used in conjunction with foundation planting, refacing can completely change the look of your foundation and your home. 

Yes, it is normal for a block foundation to crack. Some block foundation cracks are more serious than others and indicative of a larger structural problem. On the other hand, minor cracks may not be of immediate concern but should be monitored. Regardless, foundational cracks are not an uncommon response to wear on a structure from time and weather.

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

Regularly inspecting your foundation—at least the visible sections—for signs of foundation issues like moisture and pest infestation is a good way to identify slab leaks early, as is keeping an eye and ear out for water damage to indoor building materials, above-average water bills, sounds of running water when no fixtures or appliances are on, and indoor humidity that causes the temperatures to feel more extreme. If you do find any issues, contact a plumber right away to check it out for you.
