Hand-Wash · Climate-Controlled · Certified
Why
Caldwell Picks Gemstar
Four reasons we are Caldwell's most trusted detail shop — and the reason most of our work comes from referrals.
Why Caldwell Drivers Trust Us
The Idaho Defense
The Treasure Valley is rough on paint. Mag chloride brine in winter, 200+ days of UV in summer, agricultural dust year-round. We built this shop specifically for those conditions.
Hand-Wash Only
Zero tunnels, zero brushes, zero swirl-mark machines. Every wash is two-bucket, pH-neutral, with dedicated mitts.
Climate-Controlled Bays
Ceramic coatings need controlled humidity and temperature to cure properly. Our shop at 3031 Syringa Ln has them.
Manufacturer-Certified Installers
Not seasonal hires. Every ceramic install is performed by a certified detailer backed by manufacturer warranty.
Itemized Written Quotes
No bait pricing. No surprise add-ons. What we quote is what you pay. Same-day quote turnaround on every inquiry.
What Sets Us Apart
A real Caldwell address — not a Boise service-area page
Search "car detailing Caldwell" and you'll find dozens of mobile detailers and service-area listings posted from Boise. Most have no fixed bay, no insurance to your driveway, and no climate control for the work that needs it. We're at 3031 Syringa Ln in Caldwell, in our own building, in our own bays. You can drop by Monday through Saturday and stand in the bay where your vehicle will be detailed.
Manufacturer-certified ceramic install
Ceramic coatings are only as good as their install. Our lead detailer is manufacturer-certified to install our four ceramic tiers, which is what backs the multi-year warranties on the Gem Shield 1-Year, 3-Year, 5-Year, and 9-Year flagship packages. Coating warranty fine print requires certified install and proper aftercare — we deliver both.
Itemized written quotes
No "from $99" bait pricing. Every Gemstar quote is itemized — labor, materials, optional add-ons, and a fixed total. What we quote is what you pay. If we discover something during prep that changes scope (rare), we stop and call. The standard same-day turnaround on quotes means most clients book within 24 hours of asking.
100% satisfaction guarantee
If anything isn't right when you pick up your vehicle, we fix it. No fine print, no hassle, no charge. That's the only way to back hand-wash, certified-install, written-quote work with the kind of warranty terms a Caldwell driver actually wants.

What Our Clients Say
"Took my F-150 in for the 5-year ceramic and full correction. The shop walks every panel with you, gives a written quote, and actually does what they say. Two months in and the truck still beads water like the day I picked it up."
Marcus T.
"I'd been to two other 'detailers' in Caldwell who damaged my paint. Gemstar fixed all the swirl marks they'd left behind, then ceramic coated the whole car. The difference is night and day. They're the only people I'll let touch my car now."
Sarah K.
"Ran a small HVAC fleet of 6 vans. Switched to monthly fleet detailing with Gemstar last year. Invoicing is clean, scheduling is reliable, vehicles look professional on every job site. Worth every dollar."
Doug R., Canyon County HVAC
"Brought my wakeboard boat over after the Lake Lowell season for the pre-storage detail. Hard water spots that wouldn't come off with anything I'd tried. Totally gone. Gel coat looks new again."
