Build a Written Estimate by Board or Square Foot: the full procedure

Turn the takeoff into a clear written estimate priced by board count or square foot, with the finish level and texture stated so the price matches the work.

• Applies to: Estimator / owner
• Frequency: Every quoted job
• Scope: Covers converting the takeoff into a priced, written estimate the customer can approve. Does not set your rates or cover tax handling — those are business decisions; this SOP standardizes how an estimate is built and presented.

What you need

• Estimate template
• The completed takeoff
• Labor/material rate sheet
• Calculator/estimating tool
• E-signature or written approval method

The procedure, step by step

1. Start from the takeoff — Pull the board count, net square footage, finish level, and texture per area from the takeoff. Never estimate from memory or a rough walk-through.
2. Price by your unit — Apply your per-board or per-square-foot rate. State the basis on the estimate (e.g., "$X per sq ft, Level 4, smooth") so the customer sees exactly what they’re buying.
3. Adjust for finish level and texture — Add labor for higher finish levels — Level 5 skim and gloss-ready surfaces cost more than a Level 4 painted wall, and heavy texture differs from smooth. The GA-214 level on the estimate is what defines "done."
4. Add materials and access factors — Include compound, tape, bead, fasteners, primer, and any special board, plus adders for stair carries, high ceilings, or difficult access noted in the takeoff.
5. State scope and exclusions clearly — List exactly what’s included (rooms, level, texture, prime) and what’s not (paint, electrical, repairs outside scope). Clear exclusions prevent disputes.
6. Note lead-safe handling if triggered — If the lead-safe screening SOP flagged a pre-1978 RRP-triggered job, state that lead-safe handling applies and any associated cost, deferring the work itself to the EPA RRP rule.
7. Set terms — State the price, validity window, deposit (if any), payment schedule, and warranty reference. Put it in writing — verbal estimates cause disputes.
8. Deliver and get approval — Send the written estimate, walk the customer through the finish level and scope, and obtain written or e-signed approval before scheduling production.

Quality check before you finish

• The estimate is built from the takeoff’s board count/square footage, not a rough guess.
• The pricing basis (per board or per sq ft) and the GA-214 finish level are stated on the estimate.
• Finish-level and texture labor adjustments are reflected in the price.
• Inclusions and exclusions are explicit (paint, electrical, out-of-scope repairs).
• Lead-safe handling is noted if the job was RRP-triggered (defers to EPA RRP rule).
• Terms (validity, deposit, payment schedule, warranty reference) are stated.
• Written/e-signed approval is obtained before production is scheduled.

It documents the work sequence for a Drywall 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.
