Services

A discipline
of care.

Four services, each executed with the same uncompromising standard. Packages are tailored to your vehicle — because no two cars need the same touch.

01 — Exterior

Exterior Wash & Wax

A two-bucket, pH-balanced hand wash finished with a premium synthetic wax that beads water and deepens gloss for up to eight weeks.

Starting at $150
02 — Interior

Interior Deep Clean

Steam extraction, leather conditioning, vent-by-vent detailing, and fabric refresh. Every seam, stitch, and switch — handled with forensic attention.

Starting at $150
03 — Correction

Paint Correction

Multi-stage machine polishing to remove swirls, scratches, and oxidation. We refine the clearcoat until the paint reflects the world the way it should.

Starting at $350
04 — Protection

Ceramic Coating

A professional-grade SiO₂ ceramic layer bonded to corrected paint — hydrophobic, UV-resistant, and engineered to protect for years, not months.

Starting at $799

The Process

Methodical.
By design.

Detailing isn't a rush job. It's a sequence — deliberate, layered, measured. Here's how every appointment unfolds.

01

Consultation

A short conversation about your vehicle, concerns, and the finish you want. We tailor the service before we ever pick up a cloth.

02

Setup

We set up our mobile rig at your location, connect to your outdoor water spigot, and get our power, lighting, and premium products ready to go.

03

Execution

We work through the service with focus and patience, treating every panel and surface with meticulous care. No shortcuts, no rushing.

04

Handover

Once we're done, we leave your keys in a secure spot. You come back to a finished vehicle, ready to go. Easy and convenient for busy schedules.

Service Area

Clients

What owners
say.

A detail is only as good as its last client would say it was. Here's what ours have shared.

Showed up on time, worked for four hours straight, and handed back a car that genuinely looked better than the day I bought it. Worth every dollar.

Evan is the only person I'll let touch my paint now. Meticulous, polite, and the correction work he did on my hood was honestly art.

Interior detail on a family SUV that had seen two toddlers and a dog. I don't know what magic he pulled, but it smells and looks brand new.

FAQ

Good questions.

The things clients usually want to know before they book. Don't see your question? Call or text us at (302) 893-3596.

What areas do you serve?

We serve Delaware County, Chester County, and Montgomery County in Pennsylvania, New Castle County in Delaware, and the Phoenixville area. If you're on the edge of these regions, just reach out — we'll let you know.

Do I need to provide water or power?

We bring our own power, lighting, products, and tools — but we do need access to an outdoor water spigot at your location. Most homes and garages have one; if you're not sure yours works or you're parked somewhere without one, let us know when booking and we'll figure out the best plan together.

How long does a detail take?

Exterior wash and wax takes about 2 hours. Interior deep cleans run 3 to 4 hours. Paint correction is a full-day job. Ceramic coating also typically takes about a day.

How do I book an appointment?

Call or text (302) 893-3596, email evan@refinedautospas.com, or fill out the booking form below. We confirm all appointments within the hour during business hours.

What does ceramic coating actually do?

Ceramic coating creates a semi-permanent hydrophobic layer bonded to your clear coat. It protects against UV damage, chemical etching, light scratches, and contaminants, and makes washing the car dramatically easier. A professional coating typically lasts 3 to 5 years.

Do you take payment at the appointment?

Yes, we accept Venmo and cash. For larger jobs like ceramic coating, we may require a deposit at booking to reserve your time slot.
