It supports everything else – walls, windows, floors, doorways, roof – so when your foundation is damaged, it can cause serious problems throughout your home. Like most things in life, your foundation is subject to environmental stress. Expanding and contracting soil, excessive moisture and inadequate drainage are some of the most common threats to your home’s foundation. Over time, environmental stressors can cause a foundation to shift, crack or settle unevenly. And homeowners often miss early warning signs of foundation damage. Homeowners spend about $4 billion annually stabilizing faulty foundations, and those costs may increase as more homes are built in areas known for shifting soil. Understanding risk factors and signs of foundation problems can help you protect your most valuable asset from irreversible damage....

We had an excellent experience with Olshan. They installed two helical piers on a corner of our home that recently experienced some settling. They were the ONLY company of 4 that sent out an actual structural engineer (Marc S.). Their quote was the most competitive and seemed to make the most sense for what we needed to be done. It was low pressure and Marc was very patient with many subsequent qu...

Writing this based on my current experience and will update as things go along. I Fist contacted Olshan almost 2 months ago because of ongoing problems with my foundation with cracking, movement, and water getting through to the basement. I called Olshan because they did the original repair and gave a fully transferable lifetime warranty. It was not for this I would never do business with them. Si...

Service Provider Response

Mr. [Member Name Removed], Thank you for your valuable feedback. Unfortunately, some of our office staff has been working remotely due to Covid 19. We realize that our interaction with our customers have not been as seamless as usual, for which we apologize. The areas repaired 15 years ago by a previous owner are still under warranty, while repairs declined by previous owners are not covered by wa...


I went on Angie's List and I saw them there, and I wanted 3 different estimates so I got them to give me an estimate. The estimate was comparable to the other one. They were really friendly. The price was very high to me. I have lived in this house since 1964 and my floor is uneven and it has never bothered me. I had put wooden flooring in the house and they couldn't put it there because of the de...

I will reassess the issues discussed with Marc and make a determination after I check out several options for me to consider that Marc discussed with me.

Description of Work
Marc assessed my situation. He gave me several options. He explained that if Olshan did the work (exposing the outer wall and sealing the wall/foundation the price might be $10/20,000). He also made suggestions for several other options I might consider at this at least determine what is creating the areas of dampness in a portion of my basement wall. I will exercise those several options before I make a final decision, i.e., checking the french drains in the area, to be sure there is no clogging, etc. Marc was professional, on time, very knowledgeable, and I would not hesitate contacting Olshan for the larger project if I decide to go that route.

Our house was built in 1972 and had settled roughly 5" across 25' because of inadequate piering and soil drainage. Olshan installed 7 helical piers and cut 3 original builder piers. In my mind I imagined a completely level house when we were done but the reality is that remodeling over 40 years and window replacements meant to do so would cause significant damage and cost to the rest of the house ...
