"This contractor is highly skilled in their trade. From the top of the organization to the bottom of the organization, everyone was courteous, attentive, and professional. Their work was deployed quickly and well organized. Over the past decade, my organization has completed fourteen (14) complex and successful stabilization of foundations. As needs arise, we will likely continue to work in collaboration with Ram Jack West."

"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."

"The service worked out fine. They were prompt. Actually, they were delayed, but they called me and let me know that they were going to be delayed. I think I did not have a good sense of what it was they were going to do which was my problem, not theirs. They offered some insights on some things to do on a couple of things that I had questions about. It was not necessary some thing they were going to do that was covered by what I bought. I am hoping that the repair that he made on a leak would not be an issue anymore which I will find out soon. They did what they said they were going to do within reason of the $149 big deal I purchased. They came out within a week or so after I purchased the big deal. That was fine. I did not feel like it was an extensive wait to get them out. I do not have anything to compare the quality of their work against with."

Foundation Repair FAQs, answered by experts

Yes, engineers assess soil load-bearing capacity and provide construction guidelines.

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. 

The most expensive foundation repair method is to install helical piers. Helical piers are a type of steel pier used to support sinking foundations in areas with poor soil conditions or deep bedrock. This foundation repair method can cost up to $3,000 per pier, including labor, because of its material and labor-intensive installation process. Total foundation repair costs can easily reach over $20,000 using this method.

Foundation cracks that are 1/8 inch wide or less, aren’t uneven across the gap, and don’t continue widening over time are usually just normal settling cracks and don’t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.

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.
