05 Questions
Opener questions
Opener dead? What to check firstHow much is a new garage door opener installed?
Chen Garage Door installs new openers in San Rafael and across Marin from $620, with the battery backup California requires and the old unit taken away. Belt drive and wall-mount units cost more than chain drive. Code CG-OPENER takes $50 off. The quote visit is free.
Does a new opener need battery backup in California?
Yes. California Health and Safety Code section 19892 has called for battery backup on new home openers since July 1, 2019. Every opener we install carries one, so the door keeps working through a power outage.
Will a wall-mount opener fit a low garage?
Often, yes. A wall-mount unit sits beside the torsion shaft instead of on a rail down the ceiling, so it fits garages with little headroom. We measure headroom, backroom and side room before we quote.
