Measure and Quote: the full procedure
The standard way to measure an opening or existing door and produce an accurate, transparent on-site quote.
- Applies to: Field technicians and estimators
- Frequency: Every install or replacement opportunity
- Scope: Covers opening measurement, headroom/sideroom/backroom checks, product selection, and quote preparation. Spring sizing and force settings are specified per the manufacturer and a trained technician — this SOP captures measurements and pricing only.
What you need
- Tape measure
- Level
- Headroom gauge
- Product catalog / price list
- Quote form or tablet
- Calculator
The procedure, step by step
- Measure the rough opening — Measure width and height of the finished opening at multiple points. Record the widest and tallest readings to ensure clearance.
- Check headroom, sideroom, and backroom — Measure headroom above the opening, sideroom on each side, and backroom depth into the garage. Note any obstructions (pipes, lights, shelving).
- Confirm track type and door style fit — Determine the required track radius and whether standard, low-headroom, or high-lift hardware is needed based on the measured space.
- Select door and opener options — Recommend door material, insulation value, window and color options, and a UL 325 compliant opener that fits the customer's needs and budget.
- Note spring and hardware spec - defer sizing — Record the door weight and configuration so the manufacturer's spring chart and a trained technician can specify the correct spring system. Do not size or select springs by guesswork.
- Build the line-item quote — List materials, labor, disposal of the old door, and taxes as separate lines. Avoid lump-sum pricing so the customer sees what they are paying for.
- Present and explain the quote — Review each line with the customer, explain warranty coverage, and answer questions. Provide the written estimate per the Written Estimate SOP.
- Record measurements for ordering — Save all measurements and selections to the customer file so the correct door, hardware, and manufacturer-specified spring can be ordered accurately.
Quality check before you finish
- Opening measured at multiple points; widest/tallest recorded
- Headroom, sideroom, and backroom documented with obstructions noted
- Correct track/hardware type identified for the space
- Opener selected is UL 325 compliant
- Door weight recorded so spring is specified by manufacturer chart, not guessed
- Quote is itemized, not lump-sum
- Measurements and selections saved to the customer file
This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Garage Doors business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan.

Frequently asked questions
How does a tech size the spring during a quote?
The tech records the door’s weight, size, and configuration during measurement, but does not size or select the spring by guesswork. The correct torsion or extension spring is specified from the manufacturer’s spring chart by a trained technician. DASMA stresses that springs operate under extreme tension, so sizing and installation belong to trained door systems professionals.
Why measure headroom and backroom before quoting?
Because the available headroom, sideroom, and backroom determine which track and hardware configuration (standard, low-headroom, or high-lift) the door requires — and that changes both the parts list and the price. Measuring before quoting prevents ordering hardware that physically will not fit and protects the customer from a failed install.
