"Absolute WORST experience I’ve ever had with a company! They are extremely predatory and convinced my 63 year old mother that she had to sign the contract THAT DAY, and she didn’t even understand what she was signing! The first day they were scheduled to do the job, they showed up hours late, and said they “weren’t the right crew to do the job”. We then had to wait a couple weeks for a different crew to come, and when they came they said they weren’t the right crew to do the job either!! 2 weeks later, ANOTHER crew came and said THE SAME EXACT THING!!! So after 3 times of getting the runaround, I was completely FED UP with this horrible company and decided to cancel the contract. They FINALLY did let me cancel, but are demanding we still pay $600! After all they put us through over 3+ months, they had the nerve to charge us $600 for an outlet! PLEASE AVOID THEM AT ALL COSTS! All they care about is dollar signs, not about the QUALITY of their work or customer service."

"From the initial contact with Trenton Mayes, it was a very positive experience. He came to inspect, knew exactly what needed to be done and made the arrangements. The workers who performed the mold remediation were just as efficient and friendly as Trenton, great staff and great job. The product they use did not bother my asthma and I was able to return to my home."

"Had Betts Structural Engineering come and look at the foundation of a house we were in contract on. Josh came out and was professional and informative. He informed us the foundation was failing and explained what needed to be done. He throughly explained everything and told us how we could do it ourselves for much cheaper than a contractor could do it. In the end he saved us from a long and expensive process if we proceeded with the house."

Foundation Repair questions, answered by experts

It can be safe to live in a house with minor foundation problems as long as the issues are checked and monitored by a professional. Minor cracks are rarely a cause for structural concerns, but signs of leaks, sinking, or bulging walls should be strongly scrutinized by a foundation specialist. Similarly, it's always smart to hire a professional when you're concerned about buying a house with foundation repairs.

Yes, you can live with a cracked foundation—in fact, most people do. Virtually all foundations crack from normal settlement, and while settling cracks benefit from sealing to prevent water and moisture intrusion, most aren’t an issue. If you have structural cracks in your foundation, it might be safe to live in your home for some time, but you should address them immediately to prevent structure collapse and major property damage.

The best foundation repair method will depend on the issue you’re having, but usually, foundation instability is best fixed using supportive piers, like steel piers or helical piers. A professional foundation repair contractor or structural engineer should always decide what the best course of action is, and even then, it’s imperative that you also take measures to treat the underlying issue as well, like soil erosion or oversaturation from runoff.

You can use epoxy-based concrete fillers to repair small cracks and dents in the floor. For larger damages, remove any debris, then patch the cracks or holes with concrete repair products or resurface the entire floor. We recommend using fast-curing products that cure in four hours. You can also buy a pre-mixed concrete patch and leveler if you are only repairing parts of your floor.

A sinking foundation can be lifted, most often by installing piers to re-level and support the weight of the house. Depending on the cause and extent of the sinking, other methods to lift a foundation include underpinning and mudjacking. Consult a foundation repair pro to determine the best way to lift your sinking foundation.
