Missed calls and follow-up for window and glass repair: what a voicemail costs
The glass customer calls once and takes the first shop that answers. Text-back, answering setups, speed to lead and what each missed call costs a glass repair shop.
A woman stands in her kitchen at 6:40 a.m. looking at a hole where the window was. She searches "window glass repair near me", calls the first result, gets voicemail, hangs up without leaving a message, and calls the second result. The second shop answers. That is the whole story of lead flow in this trade, and it repeats a thousand times a day.
Glass customers do not leave messages and they do not call back. They are standing in front of the problem. If you miss the call, the job belongs to whoever picked up. This guide is about catching those calls, and about what to do in the first five minutes with the ones you catch.
What a missed call actually costs
Run your own numbers in the missed-call calculator. The defaults on it are from this trade: a $380 average ticket, 60 calls a month, 28% missed, and a 55% booking rate on answered calls.
At those numbers a shop misses about 17 calls a month. Nine of those would have booked. Nine jobs at $380 is roughly $3,400 a month, or about $41,000 a year, lost to voicemail. For a shop doing storefront work with a $2,000 average ticket, the same miss rate costs several times that.
The 28% figure is not pessimistic. Shops that install call tracking for the first time usually find a miss rate between 20% and 40% once you include calls that rang out while the technician was on a ladder, calls during lunch, calls after 5 p.m., and calls on Saturday. Only 28.2% of window and glass repair listings are open Saturday. The calls do not stop on Friday.
Fix one: text-back within ten seconds
The cheapest fix is an automatic text to any missed call, sent in seconds, from the same number they called:
"Hi, this is Summit Glass. Sorry we missed you, we are on a job. Reply with your name and what happened to the window and we will text back in a few minutes. For a board-up emergency, reply URGENT and we will call right now."
That message does three things. It proves the number is real and the shop is alive. It gives the customer something to do instead of calling the next shop. And it sorts the emergency from the foggy-unit inquiry so the right person responds.
Shops that turn this on typically see 30% to 50% of missed callers reply by text. Those are jobs that were gone before. Setup is a tracking number or a text-capable business line and a $30 to $100 a month tool; it pays for itself the first week.
The text has to be followed by a human within five to ten minutes. An auto-reply with no follow-up is a broken promise and the customer knows it.
Fix two: someone answers
Text-back is the floor. Answering is better. The options, in rough order of cost:
- The owner's cell with call forwarding. Free, and it works until the owner is in an attic with a sash in his hands. Pair it with text-back.
- A part-time office person, 8 to 5. $18 to $25 an hour. Answers, books, and texts customers their arrival windows. Usually pays for itself at 40 or more calls a month.
- An answering service with a glass script. $150 to $400 a month. They answer "Summit Glass, how can I help", take the address and the job type, and text the technician. Give them a one-page script with the questions that matter: which window, is it safe, is it an insulated unit, is it commercial. Insist they never say "I do not know, someone will call you".
- After-hours line for board-ups. If you take night calls, route them to a rotating technician's cell with a louder ring. Only 5.7% of shops claim 24 hours, and the ones that actually answer at midnight get the job and the replacement glass that follows.
Whatever the setup, put a tracking number on the website and the Google profile so you can see missed calls as a number every week instead of guessing.
The first five minutes after a lead comes in
Speed to lead matters as much as answering. A form submission or Meta lead that gets a reply in five minutes books at several times the rate of one that waits an hour. Most glass shops reply to web forms the next morning.
The reply, by text, in under five minutes:
"Hi Dana, this is Marco at Summit Glass. Got your note about the foggy slider. Can you text me a photo of the whole door and one close-up of the fog? I can give you a range today and we can measure this week."
Ask for the photo. It lets you quote a range immediately, it filters out the auto glass calls, and it starts a conversation instead of a game of phone tag.
Then book the measure on that same thread. Offer two times. "Thursday at 10 or Friday at 2?" works better than "when are you free".
The follow-up sequence for quotes that did not book
A foggy-unit customer who got a quote and went quiet is not lost. She is comparing or waiting for a paycheck. A simple sequence by text:
- Day 1: the quote, in writing, with the price range, the lead time and a photo of a similar finished job.
- Day 3: "Any questions on the quote? Happy to walk through the options." One line.
- Day 7: "We have an opening next week if you want to get the slider done before the cold hits." A reason to act now, not a discount.
- Day 21: a last one. "Still here when you are ready. The quote is good for 60 days."
Four texts, 20 seconds each. Shops that do this book 15% to 25% of quotes that would otherwise have died in a spreadsheet.
For commercial quotes, the same sequence by email with the certificate of insurance attached on day one.
Measure it weekly
Five numbers on a whiteboard every Monday: calls in, calls missed, missed callers recovered by text, leads replied to in under five minutes, quotes followed up. If missed calls are over 10% after a month of this, the answering setup is wrong, not the marketing. There is no point spending more on Google Ads to generate calls that ring out.
Frequently asked
Can I use my personal cell as the business line? For text-back and tracking you need a business line or a tracking number that forwards to the cell. Most tools provide one for $10 to $30 a month and it keeps your cell number off the internet.
Will customers be annoyed by an automatic text? No, if it is short, sounds human, and is followed by a real person. They are annoyed by voicemail.
What about calls I miss on purpose, like auto glass? Let text-back handle them. "We do not do auto glass, try [name]" in a reply takes five seconds and gets you a thank-you. Some of those people own houses.
