Most San Anselmo jobs are hardware on older doors. Chen Garage Door replaces a pair of lift cables from $180 and a roller set from $170, and a tune-up is $79. The quote visit is free, and you get the price before any work.
It is tune-up work, the low end of the list, and on the creek flats it is the cheapest protection the door gets.
The price follows the door: a wider or heavier door needs heavier springs and cables. Odd sizes are common here, so we measure first and give you one price for the job.
