Measure the opening and inspect the system
Record the opening width and height, headroom, backroom and side room, and note the framing condition. For repairs, document the current door, springs, cables, rollers and opener model.
Confirm the customer's selections for door style, insulation, windows and color, and the opener features they expect. Note any electrical work needed and who provides it.
- Opening: width, height, headroom, side room and backroom.
- Door and opener: model, options and accessories.
- Hardware: springs, tracks, cables and rollers.
Copyable estimate template
Start with your legal or trade name, business contact details, customer name, job address, estimate number, issue date and validity period. Add the scope below, replacing the bracketed fields with your site measurements and supplier quotes. This is a written example you can copy into your own estimate, not a submitted quote or a promised software import.
For each charge, show quantity, unit, unit price and line total. Group fixed-price work separately from allowances and optional upgrades. Finish with the subtotal, applicable tax, total, payment terms, anticipated schedule, exclusions and how the customer can accept. Verify contract, tax, licensing and deposit requirements in your jurisdiction before using it.
| Line item | Quantity or specification | Scope to confirm |
|---|---|---|
| Door | [Model / size / options] | Style, insulation, windows and color |
| Opener | [Model / accessories] | Drive type, remotes, keypad and sensors |
| Springs and hardware | [Type / quantity] | Matched to door weight and cycle rating |
| Removal and disposal | [Existing door / opener] | Hauling and site protection |
| Framing and trim | [Repairs / weather seal] | Jamb condition and exterior finish |
| Safety checks | [Reversal / balance tests] | Handover record and customer walkthrough |
Worked scope example: replace a door, keep the opener
Imagine a hypothetical customer who wants a new insulated door but believes their opener is fine. Inspect and test the opener, then list it as retained, with any parts you recommend as optional lines the customer can accept or decline.
Separate the springs from the door price so the customer sees they are matched to the new door weight. This is a structure example, not a price list.
Calculate the selling price from your own costs
Build the job cost from loaded labor, materials and subcontractor quotes, equipment, disposal and an allocated share of overhead. Loaded labor includes the cost of employing the crew, not only the hourly wage. Allow time for setup, travel, collection of materials and cleanup. Avoid adding the same overhead or contingency twice.
If your cost includes overhead and your target margin on the selling price is 20%, divide cost by 0.80. A hypothetical $2,000 cost would sell for $2,500 before applicable tax, leaving $500 at that margin. A 20% markup would instead sell for $2,400 and produce a lower margin. These figures illustrate arithmetic, not local rates or a recommended profit target.
Check actual time and supplier costs against the estimate after the job. Keep separate benchmarks for easy-access work and labor-intensive conditions; a single unit price can hide very different production times. Use the job-cost and markup-versus-margin calculators linked below to check your assumptions.
Treat springs and safety features seriously
Torsion springs store significant energy. Use trained technicians, proper tools and the manufacturer's procedures.
Test the opener's automatic reversal and photo-eye sensors after installation and record the result. Point customers to the opener's manual for monthly checks.
From accepted estimate to scheduled job and invoice
Keep the inquiry, property details, estimate version and follow-up notes together. Agree the scope and payment terms before booking the work. When something changes, record the revised scope and price and obtain the customer's agreement before proceeding; do not quietly add work to the original total.

Garage door estimate questions
Should repairs and replacements use the same template? Yes, with different lines: repairs focus on the parts replaced and the tests completed.
How do you show warranty terms? Identify the manufacturer's warranty separately from your own workmanship terms and avoid promising coverage you do not provide.
