Written Estimate: the full procedure

The standard for turning an on-site assessment into a clear, itemized written estimate the customer can approve.

What you need

The procedure, step by step

  1. Pull measurements and diagnosis — Start from the recorded measurements and diagnosis so the estimate reflects the actual job, not a guess.
  2. Itemize materials and labor — List each material, the labor, old-door disposal, and taxes as separate lines so the customer sees the breakdown.
  3. Specify manufacturer parts — Reference the door, opener, and manufacturer-specified spring/hardware so the customer and supplier know exactly what is quoted - spring sizing per the manufacturer chart and a trained technician.
  4. State scope and exclusions — Clearly state what is and is not included (e.g., electrical work, structural repairs) so there are no surprises later.
  5. Include terms, warranty, and validity — State payment terms, the warranty coverage, and how long the estimate is valid.
  6. Present the estimate to the customer — Walk through the estimate, answer questions, and avoid high-pressure tactics. Give the customer the written copy.
  7. Capture approval before work — Obtain written or e-signed approval before ordering parts or starting paid work.
  8. File the approved estimate — Save the approved estimate to the customer file and link it to the job so invoicing matches the quote.

Quality check before you finish

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. Open the tool above to print it, toggle ink-saver, or (with a free ToolFluency Business account) edit it to match your own workflow.

Frequently asked questions

Why itemize the estimate instead of giving one total?
An itemized estimate — materials, labor, disposal, and tax on separate lines — shows the customer exactly what they are paying for, builds trust, and reduces disputes at invoicing. It also makes it clear when manufacturer-specified parts like the correct spring are included, which a lump sum hides. Transparent, itemized quoting is standard good practice for consumer service work.
Where does the spring specification on the estimate come from?
The spring listed on the estimate is specified from the manufacturer’s spring chart based on the door’s measured weight and configuration, by a trained technician — not estimated by feel. This keeps the quote accurate and ensures the part ordered matches the door. Actual spring installation still defers to the manufacturer’s instructions and a trained technician because of the extreme tension involved.
