Editorial Review
Our Take on Olshan Foundation Repair
Olshan is the scale pick in Houston, with 3,691 Google reviews and named local staff behind the estimate. Its drainage work earns praise, but it prices at the high end and publishes few warranty details. Ask for terms in writing.

Things to Consider

Company Background
About Olshan Foundation Repair
Olshan Foundation Repair holds 4.9 stars from 3,691 Google reviews, and that scale is the first thing to know about its Houston branch at 5902 W. 34th Street in Northwest Houston. The company says it has repaired foundations since 1933, and the Houston office pairs structural work with the water management that clay soil demands.
Most Houston houses sit on slab foundations over expansive clay, so the job is usually to stabilize the slab and keep water away from it. Olshan lists Cable Lock ST Plus piering, helical piers, pressed concrete pilings and PolyLift foam injection for foundations, and the Olshan Drainage System for moving water off the lot. One homeowner thanked Villi and his crew for a perimeter drainage system that turned out "absolutely amazing." For older pier and beam homes the branch offers crawl space recovery and encapsulation, and the site also lists under-slab plumbing leak repair. Its drainage page does not mention French drains or sump pumps.
The Houston staff are named on the branch page, including general managers Chris Cates and Richard Solsberry, office manager Renee Lepley and certified structural technicians such as Tracy, Jake and Josh. Reviewers praise Tracy for listening and explaining cracks, and Hudson for a transparent estimate. Coverage runs from the Heights, Montrose, Meyerland and Bellaire to Katy, Sugar Land, Pearland, Kingwood and The Woodlands. Foundation evaluations are free, financing starts at $125 a month with approved credit, and the company advertises a transferable lifetime warranty without publishing the terms.
Not every review is glowing. A 3-star reviewer called the crew knowledgeable but said replaced bushes died and that the equipment raised an electric bill, and another reviewer said Olshan costs a little more than competitors.
4.9 from 3,691 Google reviews, read October 21, 2026. Olshan Foundation Repair suits owners who want a large, established company with named local staff and both foundation and drainage work under one roof. It suits less well anyone shopping on price alone or hoping for a small owner-run shop. Before booking, ask for the warranty terms in writing and ask who handles landscaping damage and site utilities. Texas has no state waterproofing licence, so there is no waterproofing number to look up. Under-slab plumbing falls under the Texas State Board of Plumbing Examiners at tsbpe.texas.gov, and the City of Houston issues permits where required.
Most of Olshan's Houston work is foundation repair itself. The branch installs Cable Lock ST Plus piers, helical piers and pressed concrete pilings, lifts sunken slab sections with PolyLift foam, and handles crawl space work on older pier and beam houses. Recent reviewers name John, the sales rep, and Ruben, the project supervisor, on a job in Bay Glen. Texas has no state licence for foundation repair, so ask for a structural engineer's letter on the pier plan and confirm in writing that the lifetime warranty transfers to the next owner. 4.9 from 3,706 Google reviews, read November 11, 2026.

Olshan Foundation Repair FAQs
Do you need a license for waterproofing and drainage work in Houston?
Texas has no state licence for waterproofing itself, so there is no waterproofing number to look up for Olshan Foundation Repair. Plumbing work such as under-slab leak repair falls under the Texas State Board of Plumbing Examiners, which you can check at tsbpe.texas.gov, and the City of Houston issues permits where a job requires one. Olshan reports an A+ BBB rating through the BBB of Greater Houston and South Texas, but its site lists no state licence numbers, so ask for any permit details in writing.
What are Olshan Foundation Repair's hours in Houston, and do they do emergency calls?
The Houston office on Google is open Monday to Thursday 8 AM to 8 PM, Friday 8 AM to 6 PM, Saturday 8 AM to 1 PM, and closed Sunday. The company's own branch page lists 8 AM to 5 PM, so call (713) 223-1900 to confirm. Olshan does not advertise emergency or 24-hour service, so a flooding problem outside those hours may need a different contractor for the first response.
