Editorial Review
Our Take on Olshan Foundation Repair
Olshan Foundation Repair is a foundation and sinkhole firm first and a water control contractor second, and several reviews describe honest field inspections. Pick it when slab movement and drainage may be connected. Look elsewhere for a simple interior sealing or sump job.

Company Background
About Olshan Foundation Repair
Olshan Foundation Repair says it has been repairing foundations since 1933, and its Tampa office at 5073 Savarese Cir (ZIP 33634) is the local branch of a multi-state foundation specialist. Be clear about what you are hiring. Google classes the business as a general contractor and its core trade is foundation and slab repair, including sinkhole remediation and soil stabilization, which matters on Tampa's sandy soil. Water control is a second line of work, and it is a real one. The company's site has dedicated pages for basement waterproofing, foundation drainage, crawl space repair and encapsulation, and exterior water management, plus bulkhead and seawall sealing.
The best-known product is the patented Cable Lock ST Plus underpinning system, offered with what the site calls an available lifetime transferable warranty. Coverage depends on which underpin option you buy, and passing it to a later owner needs paperwork within 90 days of sale and a fee. The company lists payment plans from $125 a month and free estimates. Google hours are 8 AM to 8 PM Monday to Friday and 8 AM to 1 PM Saturday, closed Sunday, while the website states a shorter weekday schedule, so confirm when you book.
Olshan Foundation Repair holds 4.5 from 74 Google reviews, read October 21, 2026. Customers praise the inspection process. One reviewer says Shawn looked at a cracked tile in a bedroom and told the family there was no concern instead of selling a sinkhole repair. Another credits Mike with explaining foundation cracks without scare tactics, and a third describes Mackenzie crawling under the house for a thorough inspection, with an invoice delivered the same day. Not every review is glowing. A July reviewer who hired the company for a pool lanai floor drain said the cleanup was poor and two voicemails went unanswered.
The site names Richard S. as Tampa general manager and does not publish a Florida licence number or insurance details. Foundation and waterproofing work in Florida generally needs a certified or registered contractor, so verify the licence number on the DBPR site at myfloridalicense.com and ask for proof of insurance before signing.
This company suits homeowners with slab settlement, cracks or suspected sinkhole movement who want an inspection first and water control handled by the same firm. It suits less well anyone who only needs a sump pump, French drain or interior sealing job from a pure waterproofing specialist. Ask which crew will do the work, what the written warranty covers and excludes, and what the transfer fee is.

Olshan Foundation Repair FAQs
Is Olshan Foundation Repair licensed and insured in Florida?
Olshan's Tampa page does not publish a Florida contractor licence number or insurance details, so check both yourself. Florida licenses contractors through the Department of Business and Professional Regulation, and you can search the company name and licence number at myfloridalicense.com. Ask Olshan for its licence number and a current certificate of insurance before signing. The site says its technicians are Certified Structural Technicians but names no certifying body.
What are Olshan Foundation Repair's Tampa hours and is there emergency service?
Google lists the Tampa office as open Monday to Friday 8 AM to 8 PM and Saturday 8 AM to 1 PM, closed Sunday. The company website states a shorter weekday schedule of 8 AM to 5 PM, so call 813-517-8633 to confirm. The pages we read do not advertise 24-hour or emergency call-outs, so ask whether urgent water intrusion can be scheduled sooner. Free estimates and inspections are offered.
Does Olshan Foundation Repair offer a warranty or financing in Tampa?
Yes to both, with conditions. The site describes an available lifetime transferable warranty on its Cable Lock ST Plus foundation system, with coverage depending on the underpin option you choose. Transferring it to a new owner needs a form, a fee and paperwork within 90 days of the sale. Payment plans start from $125 a month. Warranty terms for drainage and waterproofing work are not stated, so request them in writing. Olshan lists Tampa as its primary service area.
