"I have already had 3 other contractors attempt this job over the past 30 years with no success. I built this house and am hard to please but Bill Ferguson did an excellent job from start to finish and I would highly recommend him to anyone. He was very professional and stayed in contact throughout the job. I am in the process of doing another project and will be having them do all of the excavation work."

"Being on the coast and close to wetlands, there is a ton of water accumulation in my crawlspace. Terra Firma had a ton of work to dig out the drainage trenches but they did a wonderful job! They had a large crew that tackled different projects to get it all done in 1 day. Everyone was professional and very friendly. I will definitely use them again for my continual foundation improvements."

"I was happy with the work while it was occurring and have had no flooding since then. Of course, the proof will be when we break another rain record. I liked that there were several options for me as the customer. I did the demo work which saved me a lot of money and repaired my own wall."

"I needed to have my roof replaced along with 5 skylights.  Mid Valley Building provided a very detailed bid and the price came in at least a few thousand dollars under any other bids I received, this included the price of new skylights. Not only did they provide Excellent service, but the installation was done with honesty, integrity and professionalism.  This company is family owned and displays wonderful ethics. They showed up on time with a great crew and completed the installation in two and a half days.  Not only were they prompt, but they made sure to leave the areas around the house cleaned up every day.  I chose Owens Corning Tru Def Duration Series roofing and was so very glad I did since I'm in a high wind and rain area.  They were very courteous and a pleasure to have around.  I would not hesitate to recommend this company to anyone looking for honesty, integrity and professionalism in a contractor. I'm a very happy customer and for any other major construction or repairs to be done, they will be are my first call.  In fact, they will be doing some door replacement and decking work for me in the near future.  This was an awesome experience!  Kudos to John, the family and crew!"

Foundation Repair FAQs, answered by experts

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

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.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

Yes, a house can collapse from severe foundation problems if they are left unchecked. However, this is a rare occurrence that typically takes many years to develop, and a partial collapse is more likely than a full one. Homes on hillsides or in areas with frequent washouts are at a higher risk. Barring a natural disaster or other extreme circumstances, clear signs of major issues will be apparent long before a collapse is imminent. It is crucial to conduct routine foundation inspections and address any problem, no matter how minor it seems, as soon as possible to avoid threatening the structural integrity of your home.
