"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.

Foundation Repair questions, answered by experts

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

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.

Water damage in your home’s foundation is gradual, often beginning with small cracks that let water seep in. Over time, this weakens the foundation, which then allows in more water, causing significant structural damage. This process can take months or years to destroy your foundation, and the repairs can be very costly. Have your foundation inspected regularly to prevent significant damage.

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.

Foundation settlement should be a concern if you notice it happening suddenly and years after construction, if the settlement results in signs of structural damage in your home, or if it happens after a flood, nearby sinkhole, or earthquake. Some signs of severe foundation settlement that should prompt you to call a repair specialist include sloping or uneven floors, large cracks in your foundation, moisture issues or pest infestation in your basement or crawl space, and an uneven roofline.
