Painting estimating has its own headaches
It all lives in the square footage, number of coats and coverage per gallon. Here is what OneEstimate fixes.
Working out gallons and coats by hand
Estimating gallons per square foot and number of coats is easy to get wrong. With per-sf assemblies and coverage per coat, the material is calculated for you.
Measuring walls and ceilings on a PDF
Pulling paintable areas with deductions for openings is slow by hand. Measure the surfaces on the plan and the quantities flow into your line items.
Forgetting the prep
Patching, sanding, sealer and primer often get left out and eat your margin. With assemblies that include prep you bid the whole job.
Bids that don’t look professional
A branded PDF with a per-room breakdown and total square footage wins more work than a thrown-together spreadsheet.

A bidding day: painting contractor with OneEstimate
A building repaint comes in to bid. In OneEstimate the contractor measures wall and ceiling area, and the platform deducts doors and windows from the quantities. Each line item carries its assembly of paint, primer, coats and labor. When it’s done, net square footage and cost are ready.
- Wall and ceiling areas measured with doors and windows deducted.
- Reusable assemblies by finish type and number of coats.
- Adjust spread rate or price per gallon and everything recalculates.
