The technician (Ben) came out on time and was very professional. He was able to align our garage and make all of the necessary adjustments, relieving us of the cost of a new door. We are very grateful for his thoroughness and honesty.

Garage door experts in Windsor

Need a garage door expert in Windsor?

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 Windsor.

Much of Windsor was built in the 1990s and 2000s, so many garages have two-car steel doors and openers that are reaching the age when springs and opener parts wear out.

Keep your Windsor garage door running smoothly

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.

  • Spring balance & tension
  • Cables, rollers & hinges
  • Opener force & auto-reverse
  • Safety sensor alignment

FAQs

Windsor garage door questions

Still unsure? A technician can talk you through it on the phone.

Talk to a technicianOpen 7 daysMon–Sun, 7:00 AM – 9:00 PM(707) 210-0983See all questions →
Do you serve Windsor and Healdsburg?

Yes, both, plus Fulton and Larkfield-Wikiup.

My opener is original to the house. Should I replace it?

If it's loud, reverses on its own or doesn't have working photo-eye safety sensors, replacing it is usually worth it. If it just needs a part, we'll repair it and tell you what to expect.

Is it safe to open my garage door with a broken spring?

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.

Do you charge for estimates?

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.

What hours are you open?

We take calls and book appointments seven days a week, 7:00 AM to 9:00 PM.

Garage door stuck right now?

Call the Sebastopol shop. We answer 7 days a week, 7 AM to 9 PM.
