How quickly can you respond to an emergency?

Our elite technicians are available 24/7 and typically arrive within 30-60 minutes for emergency calls in the Sunnyvale area. We understand that a malfunctioning garage door can be a security risk, so we prioritize rapid response times. Our fully-stocked service vehicles ensure we can complete most repairs on the first visit.

What brands of garage doors do you install and service?

We work with all major garage door brands including Clopay, Amarr, Wayne Dalton, CHI, Raynor, and more. Our technicians are factory-trained and certified to install and repair doors from any manufacturer, ensuring expert service regardless of your door's brand. We also service all opener brands including LiftMaster, Chamberlain, Genie, and Linear.

Do you offer warranties on your work?

Yes, we provide comprehensive warranties on all our work. Parts typically come with manufacturer warranties ranging from 1-5 years, and our labor is backed by our own satisfaction guarantee. We stand behind every job we complete and will return to address any issues at no additional cost during the warranty period.

How do I know if my garage door springs need replacement?

Signs that your springs need replacement include: the door feels heavier than usual, the door doesn't stay open on its own, you hear loud squeaking or grinding noises, visible gaps in the spring coils, or the door opens unevenly. Springs typically last 7-10 years with normal use. Never attempt to replace springs yourself as they're under extreme tension and can cause serious injury.

Why won't my garage door close all the way?

Several issues can prevent complete closing: misaligned photo-eye sensors, obstructions in the door's path, damaged tracks, worn rollers, or limit switch problems with the opener. Our technicians can diagnose the exact cause during a service call. Often, it's a simple sensor alignment issue that can be resolved quickly.

Can you repair dents in my garage door?

Yes, we can repair many types of dents depending on the door material and damage severity. Steel and aluminum doors can often be hammered out or reinforced. For severe damage or multiple panels, panel replacement may be more cost-effective than attempting repairs. We'll provide honest recommendations based on what's best for your situation.

How long does a new garage door installation take?

A standard garage door installation typically takes 4-6 hours, including removal of the old door, installation of the new door, and setup of the opener. More complex installations with custom doors or additional modifications may take longer. We always complete installations in a single visit and thoroughly test everything before leaving.

Should I get an insulated garage door?

Insulated doors are recommended for attached garages, as they help regulate temperature and reduce energy costs. They're also quieter and more durable than non-insulated doors. For detached garages used only for parking, a non-insulated door may be sufficient. We can help you choose based on your specific needs and budget.

What's included in a new garage door installation?

Our complete installation includes: removal and disposal of your old door, installation of the new door with all hardware, installation or relocation of the opener (if needed), new weatherstripping, programming of remotes, safety inspection, and a full demonstration of operation and maintenance. We also provide a warranty covering both parts and labor.

Do you provide free estimates?

Yes, we provide free estimates for all services. For most repairs, we can give you an accurate quote over the phone based on your description. For installations or complex repairs, we offer free on-site assessments. There's never any obligation, and we'll explain all your options clearly before any work begins.

What payment methods do you accept?

We accept all major credit cards (Visa, MasterCard, American Express, Discover), cash, and checks. We also offer financing options for larger installations. Payment is due upon completion of work, and you'll receive a detailed invoice outlining all work performed and parts used.

Do you offer maintenance plans?

Yes, we offer annual maintenance plans that include comprehensive inspections, lubrication, adjustments, and priority scheduling for repairs. Regular maintenance extends the life of your door and opener while preventing costly emergency repairs. Plan members also receive discounts on parts and service calls.
