How do I check a garage door installer’s service-call response times?

Read the dispatch records, not the sales pitch. Compare when each call arrived with when a technician showed up, then look at emergency calls separately. Ask the technicians whether the stated response time is something they can meet on a busy day.

Ask for a sample of dispatch records covering both quiet weeks and storm weeks. For each call you want the time it came in, when it was scheduled, when the technician arrived and when the job closed. If the company keeps none of this, response time is a belief, not a measurement, and the owner should say so plainly.

Separate emergency calls, such as a door stuck open overnight, from routine repairs. Companies often promise a fast response to emergencies and meet it by pulling technicians off booked jobs, which pushes delays onto other customers. Look at reviews for complaints about waiting, and read the way the owner replies to them.

Then speak with the people doing the work. How many technicians are on the road, how are calls assigned, and what happens when two emergencies land together? Check also how many trucks and parts are carried, since a missing spring can turn a one-visit fix into two. Slow response often shows up first as lost customers, so compare recent bookings to older ones, and ask your accountant what the trend looks like.

Key takeaways

  • Request raw dispatch records, including the busiest weeks of the year.
  • Look at emergency calls apart from routine bookings.
  • Ask technicians what response time they can truly keep.
  • Check truck stock, since missing parts cause second visits.
