Questions
Before you book.
How much is the Signature Detail, and what's included?
$599 flat for a sedan. It includes a deep interior detail ($300), a wash, clay bar and machine wax with up to one year of protection ($299), and a free window ceramic coating ($250 value) — $849 of work for $599. SUVs and larger vehicles add $50.
How long does it take?
Most Signature Details take about 3 to 4 hours depending on vehicle size and condition. We do the interior and exterior in one visit, so you only book once.
Where do you serve?
We're mobile across San Francisco and the Peninsula — Daly City, South San Francisco, San Bruno, Millbrae, Burlingame, San Mateo, Foster City, Belmont, San Carlos, Redwood City, Menlo Park, and Palo Alto. From the Sunset to Stanford, if you can park it, we can detail it.
Do I need to provide water or power?
No. We bring our own water, power, lighting, and professional equipment. All we need is a safe place to park your car — a driveway, garage, or office lot works.
How long does the protection last?
The machine wax gives up to a year of paint protection, and the free window ceramic coating keeps your glass hydrophobic so rain beads and rolls off. We'll give you simple aftercare so it lasts.
What's the guarantee?
The Buttery-Smooth Guarantee: like glass or you don't pay. If your paint doesn't feel like glass and your interior doesn't look showroom-fresh, we make it right on the spot.
