If you need in-house auto glass and windshield work done under the same roof as your body repair, choose Gerber Collision. If you want the widest network of locations and the deepest bench of manufacturer certifications, choose Caliber Collision. Both back their work with a lifetime warranty, both are direct repair partners with most major insurers, and both deliver quality that swings more on the individual shop than on the brand name.
That last point drives most of this comparison. Neither chain is uniformly better. The right pick depends on your car, your insurer, and what kind of damage you're fixing. Here's how they stack up on the things that actually change your outcome.

Company Background
Caliber is the larger and younger of the two. Founded in Irvine, California in 1997, it grew into the biggest collision repair operator in the country through aggressive acquisition, including a 2019 merger with Abra Auto Body. In 2026, ScrapeHero counted 1,861 Caliber Collision locations across the United States, with California alone holding 318 of them (ScrapeHero, "Number of Caliber Collision locations in the USA in 2026"). Caliber is a portfolio company of private equity firm Hellman & Friedman, with Leonard Green & Partners and OMERS Private Equity holding minority stakes.
Gerber is nearly 90 years old. Phil Gerber opened an auto glass and trim shop in Chicago in 1937, and the business survived the Great Depression and World War II before the Boyd Group bought it in 2004. Under Boyd, Gerber became the company's U.S. collision brand and expanded steadily through acquisition. Boyd's footprint grew sharply in early 2026: in January 2026, Boyd Group completed its acquisition of Joe Hudson's Collision Center, adding 258 locations and pushing Boyd's North American total to 1,301 — a 25% jump (Repairer Driven News, "Boyd acquires Joe Hudson's, increasing shop count by 258," Oct. 30, 2025; Boyd Group, "Boyd Group Services Inc. Completes Acquisition of Joe Hudson's Collision Center," 2026). That total spans Gerber in the U.S. plus Boyd Autobody and Assured Automotive in Canada; the Gerber-branded U.S. network sits around 875 shops.
Caliber's U.S. count roughly doubles Gerber's. For most people that means a Caliber location is simply closer, which matters when you're arranging tows and rides during a repair.
Repair Quality and OEM Certifications
Both chains train technicians through I-CAR and hold direct manufacturer certifications, which is what lets a shop repair modern vehicles to factory spec — critical for cars with aluminum bodies, advanced driver-assistance sensors, or structural adhesives.
Caliber has the edge on breadth here. Its centers carry I-CAR Gold Class designation and OEM certifications from General Motors, Toyota, Honda, Nissan, Hyundai and Lexus, and it promotes work under BMW, Mercedes-Benz, Porsche and Subaru programs (Caliber, "OEM Certified Collision Repair"). Each certification means that specific manufacturer has signed off on Caliber's tools, training and procedures for their vehicles.
Gerber also holds manufacturer certifications and trains through I-CAR, but publishes a shorter certification list per shop. The practical takeaway: if you drive a certification-sensitive car — a late-model luxury brand, an EV, or anything with a lot of ADAS hardware — verify the specific location holds your automaker's certification before you commit, regardless of which chain you pick. Certifications live at the shop level, not the brand level.
Warranty Terms
Both chains promise a lifetime warranty on workmanship, and both exclude the usual items: rust, normal wear, and damage from a later accident.
Gerber offers a lifetime guarantee against workmanship defects for as long as you own the vehicle. The important catch is that it's tied to the original owner — Gerber's national guarantee does not transfer if you sell the car (Gerber Collision & Glass, "Our Guarantee"). Gerber also warrants its windshield replacements against leaks and defects for as long as you own the vehicle, which folds neatly into its glass business.
Caliber backs certified repairs with a written limited lifetime warranty, also good for as long as you own the vehicle (Caliber, "Collision Lifetime Warranty"). On paper the two are close. In practice, warranty disputes are one of the most common complaints against both chains (more on that below), so keep your final estimate and repair documentation regardless of which you choose. If you don't understand how insurer networks affect these guarantees, our explainer on how DRP body shop networks work covers the mechanics.
In-House Glass: Gerber's Real Differentiator
This is the clearest functional split between the two. Gerber runs its glass operation in-house as Gerber Glass, so a car that needs both body repair and a windshield replacement gets handled in one facility. Caliber focuses on collision and mechanical work and typically routes glass to a subcontractor.
If your damage is body-only, this doesn't matter. If your accident cracked the windshield or a door glass, Gerber removes a layer of coordination — one shop, one drop-off, one warranty conversation instead of juggling a separate glass vendor. For anyone dealing with combined body-and-glass damage, that convenience is a genuine reason to lean Gerber.
Customer Review Sentiment
Here the two are nearly indistinguishable, and not in a flattering way. On independent complaint aggregators in 2026, both chains sit around 1.8 out of 5. Gerber shows roughly 1.8 stars on sites like SmartCustomer and PissedConsumer; Caliber shows a similar 1.8 on PissedConsumer, alongside stronger scores on other platforms like Trustpilot-style review widgets.
The recurring complaint themes are almost identical across both brands: repair timelines that stretch past promised dates, communication gaps during the repair, occasional workmanship issues like paint mismatch, and disputes over warranty claims. Aggregator sites also skew negative by nature — satisfied customers rarely post — so treat 1.8 as a floor for the loudest complaints, not a verdict on every shop.
The honest read is that brand reputation tells you little here. A specific Caliber or Gerber location can be excellent or frustrating largely based on its local manager and technicians. Before you book, read Google reviews for the exact address you'd use, not the corporate brand.

Which Should You Choose?
- You need glass and body work together: Gerber. In-house Gerber Glass handles both under one roof and one warranty.
- You want the closest location: Usually Caliber, given its ~1,861 U.S. shops versus Gerber's ~875 — but check the map, because Gerber is dense in the Midwest and Southeast.
- You drive a certification-sensitive car: Lean Caliber for its broader OEM certification list, but confirm the specific location holds your automaker's cert either way.
- You care about warranty transferability: Neither transfers cleanly on resale; read both warranties before assuming coverage follows the car.
- Your insurer steers you: Whichever chain is in your insurer's DRP network will streamline the claim. Both partner with most major carriers.
