"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!"

"Tony Hall was awesome. I know of JES since they started in the area but never had any reason to request a free inspection until I wanted to assess the condition of my crawlspace prior to selling the house. I learned so much about the function of a crawlspace and the current condition of mine. His inspection did not reveal any emergent issues with my 25 year old house but he did take the time to show me about encapsulating my crawlspace which will improve insulation properties and keep the area just about maintenance free. Included is a 25 year warranty which is transferable should I sell the house. I completely recommend JES and their inspector Tony Hall. I will be calling them to inspect and make recommendations to my next home when purchased."

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. 

New constructions need time to “settle” and sometimes, small hairline cracks occur as a result. Larger horizontal or “stair step” cracks, however, are usually a sign of a deeper, more severe issue. It could indicate an issue with the soil beneath the home, a problem caused by an overgrown tree, or another problem.

Always hire a foundation repair contractor the moment you suspect your house doesn't have a good foundation. The longer you wait to address foundation issues, the more likely they can lead to bowing floors, cracks in walls and ceilings, sticking doors and windows, chimney and roof problems, and more. Foundation problems can also let moisture into your home, leading to water damage, mold, and mildew problems.

Crumbling concrete steps will affect your ability to drill into the material and affix a sturdy railing. If the damage is primarily cosmetic, you might be able to DIY the repair with a patch kit. If the concrete is badly crumbling, hire a professional who specializes in pouring concrete. The average concrete step repair cost is $500 from a professional, but the extent of the damage will determine your actual cost. The professional may recommend a replacement if the damage is extensive.

Yes, it is worth repairing concrete cracks. Concrete cracks are normal, and they can be hard to keep from appearing. However, it is worth repairing cracks in concrete for many reasons. For example, it’s possible to repair concrete to the point where the repair is almost invisible. Also, if the crack is left alone, it can become bigger and more expensive to fix over time.
