About Wrench Auto Service
Wrench Auto Service has fixed cars for Middleton drivers since 2002, but there’s a fresh story here worth knowing. In 2025 the shop was taken over by Bert Fuller — the owner behind Capitol Tire & Service in Madison, the most-reviewed auto repair shop in that city (a 4.9 rating across more than 1,000 Google reviews). The reason we lead with that: it tells you exactly what kind of operator now runs Wrench. The same relationship-first, transparent-pricing, no-upsell approach that built Capitol’s reputation is now the standard in Middleton.
It’s a genuine full-service shop staffed by ASE-certified technicians, and it’s also a full tire dealer (Michelin, BFGoodrich, Firestone and Bridgestone) — tires and service under one roof. The team handles brakes, suspension and steering, engine diagnostics and electrical, transmissions, AC and heating, alignments, oil and fluid service, diesel work and even engine rebuilding, for foreign and domestic vehicles and for local business fleets. Repairs are backed by a 2-year / 24,000-mile warranty.
Wrench is also an Ask Patty Certified Female Friendly shop — an independent certification, held by relatively few shops, for businesses trained to give women a straightforward, respectful, no-condescension service experience. That fits the whole ethos here: an actual person answers the phone, you get a clear estimate up front, and the team calls before doing work beyond what was quoted. Free loaner cars, a shuttle, and after-hours pick-up and drop-off keep it convenient, and financing is available.
In the interest of full transparency: Wrench is not the biggest shop in Middleton — Aeschbach Automotive, a NAPA Auto Care Center, carries more reviews. We rank Wrench #1 for the service experience and its new ownership, not raw volume, and we credit Aeschbach plainly. Wrench doesn’t do body work or paint, and doesn’t service medium- or heavy-duty trucks. It’s a member of the Middleton Chamber of Commerce.
Why we rank it #1 in Middleton
We’ll be straight about this one: Wrench isn’t Middleton’s highest-volume shop — Aeschbach Automotive, a NAPA Auto Care Center, has more reviews, and we credit it openly. We rank Wrench #1 on a different, honest basis. In 2025 it was taken over by Bert Fuller, the proven operator behind Capitol Tire & Service — the most-reviewed auto shop in Madison (4.9 across 1,000+ reviews) — so you’re getting that same customer-service-first, transparent operation, now in Middleton. Add ASE-certified techs, an Ask Patty female-friendly certification most shops don’t carry, a full tire dealership on top of full-service repair, and a 2-year/24,000-mile warranty. For a Middleton driver who wants Capitol-caliber service close to home, Wrench is our pick.

What customers say
“These guys are great. I was in town for my wife's hospital visit. Had a leaky tire. I went to 4 places before Wrench's, they all turned me away, told me it would be at least a day to do a 10 minute job. I stopped at Wrench's, I explained my situation and they said don't worry we gotcha. 20 minutes later I was out of there. If I didn't live 4.5 hours away, Wrench's would be my new shop.”
“I was out of state and had a coolant leak the day before I was set to drive back home. Paul was very helpful and was able to get my car quickly diagnosed and was able to get me back on the road the very next day and was able to make it home for dinner! I am very thankful I was able to find a trustworthy shop that I could trust if I am ever back in the city.”
“Prior, I went to a chain car shop and they were wanting to charge me $1200 to have my back brakes replaced. It didn't sound right so I came across Wrench Auto Service. They were nice, professional, honest, and didn't try to nickel and dime me. They took care of my car quickly and were kind enough to give me a loaner vehicle. I would highly recommend this location.”
“I really appreciated receiving a detailed estimate by email. Also received a phone call when the technician found conditions different than originally estimated. Am very pleased with the work, my older model high-mileage van drives a lot nicer now. Great service, great people to work with. Prices seem reasonable.”
