Best Foundation Repair Companies in Prosper, TX (2026)
Published October 31, 2026. These profiles are not independent field tests. Compare written proposals and confirm current terms directly with each provider.
Prosper sits on expansive clay soil across Collin and Denton Counties. That soil shrinks during dry summers and swells after rain, which puts ongoing stress on slab foundations—even in newer, well-built homes. If you are seeing diagonal cracks near door frames, doors that stick or no longer latch, or gaps between walls and ceilings, a foundation evaluation is a reasonable next step.
This guide covers four companies with documented service in Prosper. No company is ranked. Prices are not published by most of these firms, and no Prosper-specific measured prices were available at time of writing. Get at least two on-site quotes before committing.
What to Know Before You Call Anyone
Texas does not license foundation repair contractors as a distinct trade at the state level. Verify any contractor’s general contractor registration through the Texas Department of Licensing and Regulation (TDLR).
Warranties vary significantly. Ask for the full written warranty document—not a summary—before signing. Distinguish between a warranty on the piers or materials installed and a warranty on the outcome (i.e., that your foundation will not move further). These are different things.
A free inspection is standard in this industry. Use it to get a written scope of work, not just a verbal estimate.
The Four Companies
Pinnacle Foundation Repair
Pinnacle has a dedicated Prosper location at 202 S Coleman St, Suite 300 Unit D, Prosper, TX 75078, and a location-specific page describing Prosper’s clay soil conditions. They offer free foundation evaluations.
Warranty tiers include Lifetime, 10-Year, and 5-Year options depending on the repair method. One reviewer noted that their contract included a Lloyd’s of London-backed warranty in the event the company ceases operations—worth confirming in writing if that matters to you.
BBB status: Accredited since December 2019, rated A+, with zero complaints filed in the past three years. As of mid-2026, they carried approximately 199 reviews on BBB and a 5.0 rating across 24 reviews on their Prosper location page.
No published installed prices. On-site quote required.
Olshan Foundation Repair
Olshan has operated in Texas since 1933 and serves the DFW area with foundation repair, concrete leveling, water management, crawl space repair, and under-slab plumbing. Evaluations are conducted by Certified Structural Technicians and include a written repair plan with pricing.
Warranty: Their Cable Lock ST Plus piling carries an available Lifetime Transferable Warranty. However, multiple Trustpilot reviewers as of October 2026 disputed warranty enforcement, with at least one describing the lifetime transferable warranty as unenforceable in practice. Read the full warranty document carefully and ask specifically what voids coverage.
Pricing context: Olshan publishes a national estimate range of $7,854 to $11,086 for a typical 2,000 sq. ft. single-story home requiring underpinning. This is their own published figure, not a Prosper-specific measured price. Your actual quote may differ based on soil conditions, severity, and repair method.
Financing: Payment plans starting at $125/month, with 0% interest and up to 365-day same-as-cash options available with approved credit.
BBB status: A+ rated with over 600 verified online reviews. Combined Google and Trustindex rating of 4.9 out of 5 based on 3,704 reviews as of October 2026.
1st Choice Foundation Repair
1st Choice has served the DFW area for more than 35 years and lists Prosper explicitly in its service area. They are based in McKinney and received BBB Accreditation in March 2026, currently rated A+.
Services include slab foundation repair, pier and beam repair, concrete pressed piers, house leveling, French drains, root barriers, and drainage correction. Their preferred method uses dual-wall steel piers, which they describe as reducing the need for supplemental drainage systems.
Warranty: Steel pier installations include a lifetime transferable warranty. Confirm the full terms in writing.
Reviews are mixed depending on platform. Yelp shows 49 reviews averaging 3.6 stars as of August 2026. Angi reviews from March 2026 are predominantly 5-star. Read across multiple platforms before deciding.

What a Written Quote Should Include
Before signing any contract, your written quote should specify:

- The number and placement of piers or other supports
- What soil or site conditions the quote assumes
- The full warranty document, not a summary—including what voids it
- Whether the warranty is transferable and what the transfer process requires
- Payment schedule and any financing terms in writing
- Who performs the work (company employees vs. subcontractors)
- Timeline and what site restoration is included after work is complete
Frequently Asked Questions
Does Texas require foundation repair contractors to be licensed? Not as a distinct trade at the state level. Verify general contractor registration through TDLR and ask the company what individual certifications their technicians hold.
Why does Prosper have so many foundation issues? Prosper’s clay-heavy soil expands when wet and contracts when dry. This seasonal movement is the primary driver of foundation stress in the area, regardless of how recently a home was built.
Is a lifetime transferable warranty actually worth anything? It depends entirely on the written terms. Ask specifically: what triggers coverage, what voids it, how a claim is filed, and what happens if the company goes out of business. Some companies offer third-party insurance backing (such as Lloyd’s of London); ask whether that applies to your contract.
How many quotes should I get? At least two, preferably three. Repair methods and pier counts can vary significantly between companies for the same foundation, and those differences affect both price and long-term outcome.
Should I repair foundation issues before selling my home? A transferable warranty can be a selling point, but disclose known foundation issues to buyers regardless. Undisclosed material defects create legal exposure in Texas. Consult a real estate attorney if you are unsure what disclosure is required.
Verify all company details—including current service area, licensing status, and warranty terms—directly with each contractor before making a decision.
