Garage door installs: measure, order, lead times, install day

Why install scheduling goes wrong

A garage door install looks simple from the office: sell the door, order it, put it on the calendar. In practice there are three hand-offs where it breaks. The measure visit misses something, so the door or track kit is wrong. The supplier's ship date slips, so the install date the customer was promised is gone. Or the crew arrives to find the old opener has no outlet nearby, the customer is not home, or the panels are the wrong color.

The industry is made up of small shops that cannot absorb many wasted trips. Residential garage door installers sit in the Census finish carpentry category, which had 32,219 employer establishments in 2023^[1], and 73.5% of them had fewer than five employees^[1]. A crew that loses half a day to a wrong part is a crew that did not complete a paid install.

Keeping install dates is also how small shops win work. On average 53% of surveyed US homeowners reported difficulty finding pros in 2025^[2], and 82% of US adults at least sometimes read online ratings or reviews before buying something for the first time^[3]. A rescheduled install is exactly the kind of experience that ends up in a review, so the scheduling process is part of your marketing.

The install timeline

Map every install to the same set of milestones and make each one visible on your schedule. The table below is an example; set the timing of each step from your own orders.

The key scheduling rule is in the fifth row: do not book an install day until the door is physically in your hands and checked. Booking against a supplier's estimated ship date is the most common cause of rescheduled installs.

The measure visit checklist

1. 01

   Opening size

   Measure rough opening width and height in more than one place. Note if the opening is out of square.

2. 02

   Headroom and backroom

   Measure from the top of the opening to the ceiling or lowest obstruction, and the depth available for track and opener. Low headroom changes the track kit.

3. 03

   Side room

   Measure the space on each side of the opening for vertical track and spring hardware.

4. 04

   Jambs and header

   Check for rot, damage or missing framing that must be repaired before install. Price that repair now, not on install day.

5. 05

   Floor and obstructions

   Note slope or unevenness at the floor line and anything overhead: lights, storage racks, ductwork, sprinkler lines.

6. 06

   Power and opener

   Locate the nearest outlet for the opener and confirm whether the customer wants a new opener, a wall control, keypad or app control.

7. 07

   Style and options

   Confirm panel design, color, insulation, windows and hardware with photos or a sample. Write the exact options on the order form.

8. 08

   Photos

   Take wide and close photos of the opening, both sides, the header and the ceiling. Attach them to the job so the installer sees what the estimator saw.

Measure sheets should be signed by the estimator and checked by the office before anything is ordered. A second set of eyes on headroom and side room catches most hardware errors.

Tracking lead times honestly

Suppliers publish typical lead times, but what matters is what you actually experience. Log the order date and the received date for every order, by door line and by option (custom colors, windows, insulated models). After a few months you will know your real range.

Quote the customer a window built from that range, and tell them when you will confirm. Example wording: "Doors in this style with windows have been arriving in three to five weeks. Once the manufacturer confirms the ship date, we'll call you to book a specific install day."

When a supplier delay appears, call the customer before they call you. Give the new estimate, explain whether a stock alternative could install sooner and confirm they are still happy to wait. A delay you announce is an inconvenience; a delay the customer discovers is a complaint.

Deposits and order terms

For custom or special-order doors, take a deposit at signing and state the terms plainly on the order: what the deposit covers, when the balance is due (usually at completion) and what happens if the customer cancels after ordering. Because custom doors usually cannot be returned to the supplier, many companies make the deposit non-refundable once the order is placed, but check your state's consumer rules, including any cooling-off period for sales made in the customer's home, before you write that policy.

Keep two things separate on paper: the price of the door and opener package, and any repair work found at the measure visit, such as replacing a rotted jamb. Customers accept extra work more easily when it was itemized before the order, not discovered on install day.

Running install day

Install days are long and physical, so schedule them conservatively: one full replacement per crew per morning is a common starting point, with a second install only when both are simple and close together.

Customer access needs planning. In 2025, 81% of employed Americans worked on an average weekday, compared with 30% on an average weekend day^[4], so many customers will not be home during a weekday install. Agree in advance whether someone will be present, how the crew gets in and how the customer will see the finished work. Others can be flexible: in 2025, 35% of employed Americans did some or all of their work at home on days they worked^[4], and those customers often prefer an install on a home-working day.

Every install ends with a safety and quality close-out:

• Door balanced and travelling smoothly by hand, springs set correctly.
• Opener force and travel limits set, and the safety reversal and photo-eye tests done with the customer watching where possible. The federal entrapment-protection standard applies to automatic residential garage door operators made on or after January 1, 1993^[5], so older openers being kept should be checked and replacement offered if they lack protection.
• Old door and packaging removed as agreed, floor and driveway swept.
• Photos of the finished door, inside and out, and of the opener settings.
• Warranty registration, maintenance tips and balance collected.

Example: one install, start to finish

Example: a fictional two-crew company sells an insulated door with windows and a new opener on May 2. The measure visit notes low headroom, so the estimator orders a low-headroom track kit and photographs the ceiling. The customer pays a deposit at signing; the order goes in the same day. On May 9 the supplier confirms a ship date of May 23, and the office tells the customer to expect a booking call that week. The door arrives May 24; the installer checks it against the order and finds one hinge kit missing, which the supplier ships overnight. The office then books the install for May 28, a day the customer works from home. Install day ends with a reversal test, photos and the balance paid. The only rescheduling was avoided because the install was not booked until the door was checked.

What to schedule around

• Spring replacements and off-track repairs are urgent service calls; keep slots open for them so installs do not crowd them out. Our dispatch guide covers how to see both on one board.
• Weather: schedule installs that leave the opening exposed for long periods on dry days when possible.
• Customer moves: when a customer needs to move an install date, apply your reschedule policy consistently and offer the next open day with the door already in stock.
