"Hired then late Nov 2024. Rushed to do the job, left a darn mess in the area. Left large air pockets and caused even more damage to my home's foundation. High pressure sales, terrible work. The warranty doesn't cover anything due to Foundation Recovery does NOT stand behind their work. I'm disgusted with their dishonesty from sales to repair and management. I will be hiring a structural specialist, contacting the Attorney General and filing a complaint with the BBB. Photos will be sent to both."

"The lifting and crack sealing of my driveway and front walkway/porch was fantastic. The driveway sank a little bit a couple of months after application and they came back to lift it free of charge. However, if you need concrete flatwork done, I would suggest going elsewhere. We had two corners that needed poured because they were too damaged to lift. They had to come out to repour three times in one year, and the concrete is already starting to crack again."

Established in 1933, Olshan Foundation provides cost-effective foundation solutions to residential and commercial property owners. We proudly service homeowners in Wichita from our office in Nearby Missouri. About a quarter of the homes we visit do not require foundation repair. Services are backed by an available warranty, friendly customer support and convenient payment options. Free, no-obligation structural assessments are performed by Certified Structural Technicians. Since no two homes are alike, our Technicians carefully inspect the problems affecting your home before developing a comprehensive repair plan designed uniquely to your property. Olshan is the exclusive provider of the Cable Lock ST Plus repair system. This hybrid design combines the penetrating power of concrete with the long-term durability of steel, providing a longer, deeper more secure repair. We also offer drainage and root barriers to help prevent foundation damage. Schedule a free, no-obligation assessment now. Your home’s structural integrity depends on the strength of your foundation. 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.

"Terrible service, our front was sinking due to our fireplace. We got a quote ($28,000), for their "patented" footings - enormous metal poles under each of the house supports for the front. Pretty slick snowjob, they quoted us 3 days but took 5. They dumped all the concrete they removed in the backyard without asking and left an enormous hole in the front of the house where the fireplace is. When I (5'1" femme) asked to speak to a supervisor about the delay and dumping, they sent a good old boy (300 pds, 6'2") to scream at me in my living room. No supervisor was present to verify the work and I was not permitted to watch them. They pressured me to sign the inspection form, without me inspecting anything. They are a SCAMMMM! I would only recommend Olshan as revenge."

Since 1975 we have taken care of over 32,000 structural problems and moisture control issues. We realize that there are many companies in the area who you could choose to do business with. However, we feel as if our knowledge, experience in the industry, attention to detail, and exceptional customer service is what helps us to stand apart from everyone else.

"We hired this company because we were starting to get cracks in a basement wall that was moving slightly. The first guy, the estimator, said they would stabilize the wall and if all the drywall is taken off they will also seal the cracks while they are there. They came out early March to stabilize the wall and those guys said they will not do anything to the cracks since they were only there for the stabilization, not waterproofing since that was a separate package. Ok, no big deal we have never had any water issues so we weren't concerned, everything seemed fine. Fast forward a month and the first big rain storm- there is now water coming in from the corner of the wall they 'fixed' and another wall. We called them and they sent someone out. That guy said that's a completely separate issue, has nothing to do with the work they did. There is also now white mineral growth coming up around the bottom of the concrete footings they installed for the beams. I get that we did not hire them for water issues but that is because we didn't have any until after they did work on that wall. I hired them because I felt like they were going to treat us fairly and fix my home. I was confident that by hiring them my house would be safe and structurally sound when they were done. That ended up not the experience I had with this company. And now after spending thousands of dollars I have even more issues than I started with and will have to spend even more to fix the new problems."

Basement Waterproofing questions, answered by experts

Finding water under your sink can throw a wrench in your day, but acting quickly can prevent water damage. Soak up water with a towel, then put a fan or dehumidifier near the open cabinet to dry it as fast as possible. If any mold or mildew has formed, you may need to replace the bottom of the cabinet.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Since basements are prone to water and moisture issues and the resulting problems can be expensive to repair and potentially damaging to your home, basement waterproofing is almost always worthwhile. Even for homes that haven’t experienced water infiltration, waterproofing the basement is insurance against facing expensive repair bills in the future. All basements will leak at some point, so fixing drainage issues and taking steps to prevent moisture and water infiltration is wise.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
