"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"

"Specialty Design Coatings was very professional, reliable and did a great job in repairing the cracks in our concrete, refinishing, repainting, and resealing our stone. They worked diligently throughout the project, and continuously worked each day. Oscar, the Project Manager, was easy to communicate with and very knowledgeable. The owner also stopped by to ensure everything was going well. The results of their work was outstanding."

"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

Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.
