On-Site Vehicle Repair — Brake Job and Oil Change
Location: 4412 Tanner Creek Rd, customer driveway (confirmed level surface, off-street access). Vehicle: 2019 Honda CR-V EX-L, approx. 74,000 miles. Scheduled services: front brake pad and rotor replacement, full synthetic oil change with filter.
A $75 on-site diagnostic fee applies to all service calls. This fee covers travel to location and the first 45 minutes of inspection time. It is applied in full toward labor if any recommended repair is approved at time of service. If no repair is authorized, the diagnostic fee is due at conclusion of the visit. For this appointment, a pre-repair inspection of the brake system will confirm rotor condition and verify no additional caliper or hardware replacement is needed before parts are ordered.
Front brake service: — Remove and inspect front calipers, rotors, and hardware — Replace front brake pads (OEM-equivalent, semi-metallic) — Replace front rotors (slotted, OEM-spec fitment) — Clean caliper slides, repack with brake-rated grease — Torque lug nuts to spec (103 ft-lbs for this vehicle) — Road test: confirm brake feel, no vibration or pull Full synthetic oil change: — Drain and replace 5 quarts 0W-20 full synthetic (Honda specification) — Replace OEM oil filter — Reset oil life monitor — Check and top off windshield washer fluid, coolant reservoir (visual)
Trip fee: $75 (applied toward labor on approved repair) Front brake service: — Front brake pads (set): $48 — Front rotors (pair): $86 — Hardware and grease kit: $14 — Parts subtotal: $148 + 30% markup = $192 — Labor (brake service, est. 1.5 hrs @ $95/hr): $143 Brake job total: $335 Oil change: — 5 qts 0W-20 full synthetic + filter: $38 + 30% markup = $49 — Labor (oil change, est. 25 min): $40 Oil change total: $89 Total due at completion: $424 Payment: cash, Venmo, or Zelle. Card accepted with 3% processing fee.
Brake parts and labor: 12 months or 12,000 miles, whichever comes first. Covers defective parts and installation errors. Does not cover wear from overloading, racing, or modifications. Oil change: no defect warranty on consumables; if an oil leak is identified within 7 days that traces to the drain plug or filter, return visit is at no charge.

Create Your Free AccountItemize the trip fee separately, never bury it in labor. Clients who see a $95 trip fee listed clearly will pay it without complaint. Clients who find a $95 trip fee absorbed into a vague 'service fee' will argue about it every time. List the trip fee, state what it covers (travel to location, first 30 minutes of diagnostic time), and state that it applies toward labor if the repair proceeds. That structure answers 80% of the questions before they get asked.
Parts markup is standard practice — explain it once so you don't have to defend it twice. Mobile mechanics typically mark up parts 20–40% over cost. The proposal is the right place to say so. One sentence: 'Parts are sourced at our cost and marked up 30% to cover procurement, warranty handling, and parts runs.' Clients who push back were going to push back regardless. The ones who accept it — which is most of them — now understand why it costs what it costs.
Split diagnostic into a fee and a waiver, not a free check. A 'free diagnostic' sounds like a favor and attracts price-shoppers who will use your assessment to get parts at AutoZone. A $65 diagnostic fee that gets applied toward any approved repair tells clients you value your time and screens for serious repair intent. State it clearly in the proposal under a 'Diagnostic Policy' heading — not in fine print.
Name what you can and can't do on-site. Mobile mechanics get calls they can't fulfill in a driveway — transmission rebuilds, tire mounting without a balancer, anything requiring a lift for extended access. Your proposal should list the work types you perform on-site and note that shop-required work will be referred or quoted separately. Clients who know this upfront don't feel misled when you arrive and have to refer the job. Clients who don't know it feel like they were bait-and-switched.
Quote brake jobs as a package, not by part. 'Front brake pad and rotor replacement: $285 parts and labor' closes faster than an itemized parts list that invites comparison shopping. The customer who Googles the rotor price will find a bare part and ignore your markup, warranty, and the 90 minutes of their day you're saving them. Bundle the job, state the warranty (12 months or 12,000 miles is standard), and let the package price stand on its own.
