iHow this is made

This summary is generated from the verified data on this profile: services, service area, credentials, warranty terms and the company's Google review record. It is reviewed by an editor before publishing and refreshed whenever the underlying data changes. Nothing here is asserted that is not stated elsewhere on this page.

Editorial Standards

G.L. Hunt Foundation Repair is a family-owned Texas company that Gary Hunt started in Fort Worth in 1987 and his son-in-law Hayden Slack has led since 2015. In San Antonio it works from a Whirlwind Drive office in the 78217 area and a second office on West Interstate 10. Foundation repair on slab and pier and beam homes is the core business, and the site pairs it with French drains, surface drains, sump pumps, gutters and crawl space encapsulation. It does not list interior or below grade waterproofing, so treat it as a foundation firm with real water control services. Google shows 4.9 from 2,422 reviews, read October 21, 2026. Hours run to 7 p.m. on weekdays and include weekends, and free estimates are offered.

Editorial Review

Our Take on G.L. Hunt Foundation Repair

G.L. Hunt is a foundation repairer with genuine drainage services, not a dedicated waterproofer. With 4.9 from 2,422 Google reviews and technicians that customers name, it is a strong choice for clay driven movement, and a weaker one if you need interior waterproofing.

Best forSan Antonio homes with foundation movement and drainage problems

What We Like

  • Family-owned since 1987, led by owner and CEO Hayden Slack since 2015
  • French drains, surface drains, sump pumps, gutters and crawl space encapsulation are all listed
  • Limited lifetime transferable warranty on slab piers and 25 years on TexJack piers
  • 4.9 from 2,422 Google reviews, with staff praised by first name
  • Two San Antonio offices, open until 7 p.m. weekdays and on weekends

Things to Consider

  • Foundation repair is the core trade, and the site lists no interior or below grade waterproofing
  • The drainage installation warranty is one year, far shorter than the lifetime pier warranty
  • One reviewer reported calls routed to the Dallas area, a longer French drain job than quoted, and a quote that already included a 10% discount

    If you’ve had a negative experience with this company, please file a complaint with the BBB ASAP. Please check out their Better Business Bureau page where you can find approximately two pages of lengthy, very serious customer complaints. Also please consider reporting any suspected deceptive business practices to the Texas Attorney General’s Consumer Protection Division, the Federal Trade Commission and other appropriate consumer protection authorities.<br><br>Don’t stay silent. Share your experiences, document what happened, and help other homeowners avoid potentially costly mistakes. Your home is one of your biggest investments, and you deserve a company that treats it with care and integrity, not simply as another opportunity to make money.

    Great at Selling the Product, but Very Disappointing Execution and Customer Experience<br><br>They did a very good job selling their services and setting expectations upfront. Unfortunately, the actual quality of the work and the overall experience did not live up to what was promised.<br><br>There were several unexpected changes, additional costs, and concerns that should have been identified and discussed before the project began, especially considering their claimed expertise in foundation repair.<br><br>For example, I was later informed that my home had an additional section of foundation near the patio. Addressing this section would cost approximately 30% more than the original quoted price to properly lift the entire house. Since I was not willing to pay that substantial additional amount, the house ultimately was not lifted as originally presented to me.<br><br>On top of that, I was charged nearly $1,000 extra for additional foundation thickness, something that had never been discussed or explained before I signed the contract. By the time this additional cost came up, the work had already started, leaving me with very little opportunity to reconsider or stop the project.<br><br>Unfortunately, the problems did not end there. During the partial lifting process, the house buckled, resulting in additional damage to the interior tile. This cost me another approximately $1,000 to repair.<br><br>To make matters worse, the final invoice included charges for more work than what was actually performed, including the number of breakouts completed. I had to go back and forth with their team through multiple emails just to resolve a relatively straightforward billing discrepancy.<br><br>Overall, while their sales team does an excellent job presenting and selling the service, the lack of upfront communication, unexpected expenses, issues during execution, and billing discrepancies made this an extremely frustrating experience.<br><br>VERY UNPROFESSIONAL, DISSATISFIED<br>AND NOT RECOMMENDED.

    Brucks came by my residence ànd gave me an honest and clear assessment! He answered all my inquiries and provided à detailed explanation. It’s evident these guys aren’t out to nickel and dime you like most contractors. They are upfront and honest from the very start! Integrity alone speaks volumes àbout à company! If I am ever in need of foundation repair I will only contact G.L. Foundation Repair.

Company Background

About G.L. Hunt Foundation Repair

G.L. Hunt Foundation Repair began in Fort Worth in 1987, when Gary Hunt started it on a handshake, and it has been run since 2015 by his son-in-law, Hayden Slack. The San Antonio branch works from 4827 Whirlwind Drive in the 78217 area, with a second office on West Interstate 10, and the company's San Antonio page speaks to Northeast neighborhoods such as Longs Creek, Northern Hills and Royal Ridge, as well as King William, Monte Vista, Stone Oak and Live Oak.

This is a foundation repairer first. It sets slab piers in concrete, steel hybrid and steel versions, uses TexJack and Sonotube supports under pier and beam homes, and does polyurethane foam concrete lifting. The water side is real but secondary: its site lists French drain installation, surface drains, sump pumps, gutters, crawl space encapsulation and dehumidifiers. It does not list interior basement waterproofing or exterior membranes. Its own page ties the work to expansive Black Gumbo clay in the Northeast and limestone cavities that can cause sinkholes.

Reviewers name the people they met. Matt did an elevation survey for one homeowner and told them nothing needed fixing. Buck inspected two houses for another, and Josh answered a couple's questions throughout a repair. Marfe fielded questions from a customer before the job. The fair criticism comes from a 3 star review of a French drain job: it took two and a half days instead of one, calls were routed to the Dallas area, and the 10% manager discount was already built into the quote. The drainage installation warranty is one year, against a limited lifetime transferable warranty on slab piers. G.L. Hunt holds 4.9 from 2,422 Google reviews, read October 21, 2026.

Texas has no state licence for waterproofing or foundation repair contractors. Plumbing work needs a TSBPE licensed plumber, and structural engineers are licensed by the Texas Board of Professional Engineers and Land Surveyors. Check the City of San Antonio permit requirement for your job, ask for proof of insurance, and confirm the business on the Texas Secretary of State search.

It suits owners of slab or pier and beam homes whose trouble comes from clay movement and poor drainage. It suits less well anyone who wants interior waterproofing, since the site does not list it. Before booking, ask for the written estimate, how long each phase will take, the warranty for each part of the job, and a direct San Antonio contact number.

For foundation repair, which is most of G.L. Hunt's San Antonio work, crews install concrete, steel hybrid and steel slab piers, TexJack and Sonotube supports under pier and beam homes, and foam concrete lifting. Slab piers carry a limited lifetime transferable warranty and TexJack piers 25 years. Recent reviewers name Brucks and Jesus for clear, unhurried assessments, and one said the company stood behind a transferred warranty on ceiling cracks. Texas has no state licence for foundation repair, so ask for an engineer's letter on the pier plan. 4.9 from 2,428 Google reviews, read November 11, 2026.
