Garage door experts in Sonoma
If your garage door won't open, has a broken spring, is grinding along its tracks or has come off them, our crew can help. We handle repair, replacement, installation, opener work, cables, maintenance and driveway gates for homes across Sonoma.
The Sonoma Valley has historic homes near the Plaza, ranch houses and vineyard properties with detached garages and custom doors. Hot, dry summers bake seals and lubricant, so doors here benefit from yearly service.

Openers · Springs · Cables
Hot, dry summers are hard on garage doors. Heat dries out weather seals, bakes the lubricant off rollers and hinges, and makes openers work harder in a warm garage.
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.
