Attention to detail is our specialty.
At Granum’s Garage, we believe vehicle care should be simple, sustainable, and done right. We’re a small, independent garage in Southern California offering everything from mobile maintenance details to full-scale restorations in our shop.
Our detailing services cover it all:
Exterior & Interior Detailing – thorough cleaning, protecting, and restoring every surface
Paint Correction – removing swirls, scratches, and imperfections for a flawless finish
Ceramic Coatings – long-lasting protection that enhances gloss and shields your paint
Engine Bay Cleaning – safe, detailed cleaning for better performance and presentation
Headlight Restoration – restoring clarity and improving nighttime visibility
Trim & Plastic Renewal – reviving faded trim for a factory-fresh look
Upholstery & Carpet Care – deep cleaning and stain removal for a fresh interior
Part Upgrades & Installs – from new headlights to upgraded audio units
When we’re mobile, we focus on efficient, eco-friendly maintenance details that keep your car fresh between bigger jobs. At the shop, we take the time for deep restorations and custom upgrades that bring your vehicle back to life.
We’re not for everyone—we work with clients who share our passion for craftsmanship, quality, and sustainability. By keeping most of our work in the shop, we reduce chemical runoff, conserve water, and control waste, making sure our detailing is as kind to the planet as it is to your car.

Meet the owner!
Colby Granum is the owner of Granum's Garage, and a dedicated automotive professional with 5+ years experience in the field. When he's not detailing, you can probably catch him at an automotive show somewhere!
"I've been washing cars ever since I was little, constantly helping my dad clean his trucks and trailers. Eventually, I took a few AutoTech classes in highschool and fell even deeper in love with vehicles. After buying my first car (A Daewoo Nubira CDX), I began to care for vehicles a bit more than just oil changes and general maintenance. After running a different side hustle for a few years and being successful, I decided to switch it up a bit and merge my passion for business and detailing into one, forming Granum's Garage!"
