Openers · Springs · Cables
West county fog and winter rain keep garage doors damp for months. Moisture rusts springs, cables, rollers and bottom brackets, and wood doors swell and stick.
A yearly service catches worn parts before they fail. We inspect the whole system, tighten hardware, lubricate moving parts, balance the springs, set opener force and test the auto-reverse.

FAQs
Still unsure? A technician can talk you through it on the phone.
Yes. We replace one-piece swing-up doors with sectional doors, which are safer, quieter and work with automatic openers.
Yes, all of Petaluma, plus Penngrove and nearby rural areas.
No. The springs carry almost the entire weight of the door. With one broken, the door can drop fast. Leave it closed, keep the car out of its path, and call us.
Estimates for new garage doors and gates are free. For repairs, the technician explains what failed and what it costs to fix before any work starts.
