"My experience with Copper Fox was absolutely terrible. The sales representative, Harold, assured me the project was 2-3 weeks. We started the project in early May. Copper Fox was very gracious and took a two hour lunch break instead of a one hour lunch break everyday so that my son could sleep. I knew that this accommodation would likely make the project take a little longer, but would only affect the loud portion of construction which was framing and some of the screwing during the installation of drywall. Copper Fox did not finish the project until the end of September because they failed to order materials in a timely manner. On top of the project delay the workmanship was extremely shoddy and they failed to communicate with me in a timely manner. Their "project manager" barely came to site and didn't show up for the final inspection I had to handle it myself. I am happy to share my contract and all email correspondence."

"Very, very disappointing experience; Lux replaced the foundation of my 1850 log cabin. The design was bad, the communication was bad, the execution was bad. Throughout the entire process, they were making mistakes. I now need to pay another company to fix the mess they left behind. I would strongly suggest not using this company!"

Foundation Repair questions, answered by experts

If your foundation repair claim gets denied, the first step is to carefully read over your policy and denial letter so you understand the reason for the denial. Then, gather evidence and documents that can support your case and appeal the denial with your insurance company. If your insurer does not eventually honor your claim, you may want to file a complaint with the insurance department in your state. In some cases, it may make sense to work with an attorney and file a lawsuit.

Although it is possible for a house to collapse from a sinking foundation, it will likely take many years, and signs of major issues will be apparent for a while. Homes on hillsides or in areas that experience frequent washouts are at a higher risk of collapse. Still, barring a natural disaster or extreme circumstances, houses are unlikely to fully collapse from foundation damage.

Detailed inspections and tests to determine the extent and cause.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Yes, all basement floors crack in response to the natural settlement of the soil around them and from concrete shrinkage as it cures, and you’ll see hairline cracks as a result. However, you should keep an eye on your basement floor to see if cracks continue to lengthen or widen or show signs of water intrusion. In any of these cases, the problem is likely not settling or shrinkage, and a professional repair is necessary.
