Gilsum customers

New insulated door on a detached garage I use as a workshop. Huge difference in there this winter, and the install crew was tidy about it.

Rachel D. · Gilsum

Booked a tune-up because the door was getting loud. Rollers and a hinge, done in under an hour.

Martin S. · Gilsum

Called four places. This was the only one where an actual person picked up on a Sunday. He got the door closed so we could lock up and came back Monday to finish it.

Commercial Garage Door Repair questions

Can you replace just one broken garage door spring?

Yes, and sometimes that is the right call. But on a two-spring door the second spring has taken the same number of cycles as the one that broke, so it is usually close behind. We will give you the price both ways and let you choose.

Do you charge to come out and look at the door?

We give you a price for the repair before any work begins, and we do not add a separate call-out charge on top of an approved repair in Gilsum. If you decide not to go ahead, you will know that before we start.

Do you install new garage doors in Gilsum as well as repair them?

We do. New garage door installation in Gilsum covers steel, insulated, carriage-style and glass panel doors, plus the track, springs and opener sized to the door. We measure the opening and the headroom first so the quote is real.

How long does a new garage door installation take?

A standard single or double door in Gilsum is typically a half-day job including removing the old door, setting the new sections, tensioning the springs and testing the opener. Custom and commercial doors can take longer.
