Winter is coming
Winterize before the salt does its work
Road salt and liquid brine get trapped in seams and attack the frame, brake lines, and fuel lines. Our Frame Preservation Treatment is built to neutralize winter damage and prevent future rust.
Add tires, a battery test, and a winter safety inspection, and your car goes into the season ready instead of hoping.

If you hear it, feel it, or the light is on, start with a check.
Brakes

Seasonal service
Winterizing and Frame Preservation in Portsmouth, NH
Winter on the Seacoast means salt, brine, cold starts, and short days. Get ahead of it with undercoating and rust treatment, tires, a battery test, and a winter safety inspection.
Lead service
Frame Preservation Treatment
Neutralize Winter Damage and Prevent Future Rust, Starting at $299.
Road salt and liquid brine get trapped in seams and attack the frame, brake lines, and fuel lines. Left alone, that turns into rust you cannot see until it becomes a repair bill or a safety problem.
This treatment covers undercoating and rust treatment for the underside of your vehicle. Protect before winter, and neutralize after winter, because both directions matter on New Hampshire roads.
Price as posted on the shop Facebook Page and to be confirmed before the site goes live.
Winter Safety Inspection
A full look at suspension, brakes, steering, fluids, lights, wipers, heat and defrost. The systems you count on most when the weather turns.
Tires
Low tread, uneven wear, or a car that pulls to one side will only get worse on snow and ice. We check tread and pressure, and rotate tires so they wear evenly.
Batteries
Cold mornings are when a weak battery quits. If your car cranks slowly or the lights dim at idle, get a battery test before it leaves you in a parking lot.

What we do
Auto Repair Services in Portsmouth, NH
Two repair bays for foreign and domestic service, with fuel and repair in one stop. Not sure which of these fits what your car is doing? Book a 15 minute check on the Contact page and we will tell you straight.
1. Oil Changes and Scheduled Maintenance
Due by miles, due by time, or the reminder light is on? Fresh oil and the right filter keep an engine alive, and every oil change here includes a FREE Safety Inspection.
2. Voluntary Safety Inspections
Winter readiness, pre trip, and pre purchase checks for drivers who want to know their car is safe. This is not a state inspection. New Hampshire no longer requires the old sticker, being safe is still your job and ours.
3. Brakes
Squealing brakes, a grinding sound, or a car that takes longer to stop are all warnings. We inspect pads and rotors and tell you what needs doing now and what can wait.
4. Tires and Wheels
Car pulls to one side, a tire keeps losing air, or the TPMS light will not go out? Rotation, flat repair, balancing, and TPMS service, plus tread and pressure checks.
5. Batteries and Electrical
Slow starts, clicking when you turn the key, or lights that flicker point at the battery, starter, or alternator. We test first, then replace only what has failed.
6. Heating, Cooling, and AC
AC blows warm in July, or the heat blows cold in January? AC service and recharge, radiator and cooling system work, and help with overheating before it strands you.
7. Engine and Diagnostics
Check engine light on, rough idle, stalling, or power that is not there anymore? We run diagnostics, find the cause, and give you an estimate you can approve by text.
8. Steering, Suspension, and Exhaust
Clunks over bumps, a bounce that will not settle, loose steering, or an exhaust that suddenly got loud. We inspect steering and suspension parts and the exhaust system.
9. Fluids, Filters, Belts, and Hoses
Old fluids, clogged filters, and cracked belts cause bigger bills later. Coolant, brake, and power steering fluid services, air and cabin filters, belts, and hoses.
10. Foreign and Domestic Service
Daily drivers, family cars, and work vehicles, foreign and domestic. One local shop that knows your car and knows you by name.
11. Transmission Fluid Service and Diagnostics
Shifting feels late, rough, or just not right? We offer transmission fluid service and diagnostics. If it needs more, we will tell you straight.
12. Winterizing and Undercoating
Frame Preservation Treatment, tires, batteries, and a winter safety inspection to get ready for salt season.
Hear something, feel something, see a light?
That is exactly what the 15 minute check is for. Call or book online, any time.

Portsmouth Sunoco is a family owned and operated business serving the Seacoast. Through various locations, the family has been serving the Seacoast since 1994.
Known by name, not by ticket number
Customers here are known by name. You fuel up and get your car serviced in one stop, and you talk to people who remember your car and how you use it.
Your safety matters, and doing the job right matters even more. That’s why every oil change includes a complimentary multi-point safety inspection. When we take a look under the hood, we give it to you straight: exactly what needs fixing today, and what can safely wait for later. No pressure, no upselling.
Shop story, owner photos, and a fuller history will be filled in here later for this demo. No names or timeline details have been added beyond what the family has confirmed.
Support Local Business
