Customer work and feedback
Garage door repair work on Mercer Island.
A local roller replacement led to a spring repair on a second door.
Garage Door Roller Replacement in Mercer Island
★★★★★
“Wes came out to replace the rollers on my garage door after I found his business on Groupon, and I couldn’t be happier with the service.”
Euler G.Mercer Island customer · Review excerpt
Euler first needed worn rollers replaced. During the inspection, his second garage door was unusually heavy because its spring was not providing proper counterbalance. After I explained the issue, he approved a spring replacement, and I tested both doors. See roller replacement and hardware repairs or garage door spring repair for a similar problem.

Before you book
Garage door questions in Mercer Island.
How do I arrange a garage door visit in Mercer Island?
Tell Wesley the Mercer Island address and any access or parking constraints when confirming the visit. Call or use the scheduler to check the next available opening. Availability depends on the route, schedule and parts required.
Which areas do you serve around Mercer Island?
Mercer Island is served as an island community in the Lake Washington area. You can also find service information for Bellevue, Seattle and Newcastle. Confirm availability for your exact address when booking.
What warranty comes with the work?
Trinitron warranty coverage is 2 years on parts and pieces, 1 year on motors and 90 days on labor. Contact Wesley with your invoice and a description of the concern if you need support after service.
Can I replace the opener and keep my current door?
That may be an option when the door is in suitable condition. I check its balance, travel and hardware before recommending a replacement opener, so the new motor is not compensating for a door problem.
Can I compare a repair with replacement?
Yes. The decision should account for the fault, the condition of the door and the work each option needs. Wesley explains those choices and confirms pricing before you approve the work.
How can I describe an intermittent door problem?
Note whether it happens opening, closing or both, and whether a wall control behaves differently from a remote. Do not repeatedly run a door that is crooked, damaged or unsafe. Share a photo or existing video only if it can be taken safely.
