From routine maintenance to complex repairs, Dennison's Autocare delivers honest, high-quality service right here in Portland. Your car deserves the best — and so do you.
What We Do
Complete Auto Care, Under One Roof
Whether it's a check-engine light, a squeaky brake, or a full tune-up — we've got you covered with transparent pricing and no surprises.
Engine Diagnostics
Check-engine light on? We'll pinpoint the issue fast with professional-grade scan tools and give you a clear, honest assessment — not a guess.
Brake Service
Pads, rotors, calipers — whatever your brakes need, we'll do it right the first time. Squeaks, grinding, or a soft pedal? Don't wait.
Oil Changes
Regular oil changes keep your engine running smooth and extend its life. We use quality synthetic and conventional oils suited to your vehicle.
Transmission Care
Slipping gears, delayed shifts, or fluid leaks — our transmission experts diagnose and repair to keep your drive smooth and reliable.
Heating & A/C
Maine winters are tough on your car's heating system, and summer heat demands a strong A/C. We handle both so you stay comfortable year-round.
State Inspection
Stay compliant and safe with our thorough Maine state inspection service. Quick, professional, and done right — so you can hit the road with peace of mind.
