Painting Estimate Checklist: 20 Things to Check Before You Send a Quote
Share
A painting quote can look complete and still carry expensive gaps. The problem is rarely one dramatic mistake. More often it is a collection of small assumptions: an access issue that was not priced, repairs that were not defined, extra coats that were treated as unlikely, or labour hours that do not match the actual preparation required.
Before you send the next quote, run a deliberate pre-send review. The aim is not to make the estimate longer. It is to make the commercial assumptions visible while you still have the option to change the price, clarify the scope or exclude work.
1. Have you defined exactly what is being painted?
List the included areas and surfaces rather than relying on a broad phrase such as “full repaint”. Separate walls, ceilings, doors, frames, trims, windows, balustrades, metalwork, external cladding and other significant substrates where relevant.
2. Have you checked what is not being painted?
Exclusions matter because customers can interpret silence as inclusion. Identify areas, surfaces or items that are specifically excluded, particularly where adjacent finishes may appear visually connected to the quoted work.
3. Is the measured quantity reliable?
Check the source of every important quantity. Was it measured on site, taken from drawings, estimated from photographs or assumed from a floor plan? If a dimension is uncertain, record the uncertainty rather than treating it as a fact.
4. Have you allowed for the actual substrate condition?
Preparation time is driven by condition, not simply square metres. Look for peeling or flaking coatings, chalking, cracks, failed sealants, corrosion, water staining, mould, damaged plaster, timber deterioration and previous coating failure.
5. Are repairs clearly separated from painting?
If repairs are included, define their extent. If the extent cannot reasonably be known before work starts, state the allowance or the mechanism for dealing with additional repairs. Do not let an undefined repair obligation sit invisibly inside a fixed painting price.
6. Does the preparation method match the condition?
Confirm what the job actually requires: washing, scraping, sanding, filling, caulking, patching, rust treatment, feathering edges, spot priming or more extensive coating removal. A generic “prepare surfaces” line can hide a large labour difference.
7. Have you allowed for access?
Check ladders, mobile scaffold, fixed scaffold, boom lifts, knuckle booms, restricted access, roof access, traffic control, confined work areas and repeated mobilisation. Access affects labour productivity as well as plant cost.
8. Is the coating system complete?
Check primers, sealers, undercoats and finish coats, not just the final product. Different substrates and existing coatings can require different systems. Product selection and application should follow the relevant manufacturer guidance and project specification.
9. Have you allowed for colour and coverage risk?
Strong colour changes, deep bases, bright colours, low-hiding colours and changes between light and dark finishes can require additional coats. If coat numbers depend on colour selection or coverage, make that assumption visible.
10. Are special finishes or different sheen levels identified?
Separate low sheen, semi-gloss, gloss, textured coatings, protective coatings, stains, clear finishes and other specialist systems. They often change preparation, application method, labour rate or material consumption.
11. Do the labour hours reflect the method of work?
Review the labour build-up independently of the final price. Ask whether the hours make sense for setup, protection, preparation, application, drying constraints, movement between areas, cleaning and final touch-ups. A price can appear acceptable while the labour allowance underneath it is unrealistic.
12. Have you included non-painting labour?
Loading, unloading, masking, moving equipment, inductions, toolbox requirements, daily setup, cleanup, travel within large sites, moving access equipment and customer coordination all consume hours even though no paint is being applied.
13. Are material quantities and wastage realistic?
Check spread rates, number of coats, pack sizes, substrate porosity, overspray or roller losses and practical wastage. A material allowance based only on theoretical coverage can be too lean.
14. Have you captured plant, consumables and direct job costs?
Include access equipment, abrasives, masking materials, fillers, sealants, sundries, disposal, parking, delivery charges and other project-specific costs where they are material to the job.
15. Are supervision and project-control requirements allowed for?
Commercial, strata and larger residential jobs can require meetings, inductions, staging, daily coordination, quality checks, documentation, photos, sign-offs and defect close-out. These requirements use real resources and should not disappear into overhead by accident.
16. Have you checked the programme assumptions?
Confirm working hours, staging, occupied areas, other trades, weather exposure, shutdown windows and whether the customer expects continuous attendance. A compressed or fragmented programme can change labour efficiency significantly.
17. Are assumptions, exclusions and work by others written down?
Review the quote from the customer's perspective. If the price relies on clear access, empty rooms, repairs by others, power or water availability, completed building work, approved colours or another condition, state it.
18. Are the likely variation triggers identifiable?
Think ahead to what could legitimately change the price: concealed defects, additional repairs, changed colours, extra coats, inaccessible areas, changed staging, added surfaces or client-directed scope changes. A good quote defines the baseline clearly enough that a later change can be recognised as a change.
19. Does the gross margin still work after all direct costs?
Calculate gross margin from the estimate rather than relying on markup alone. A simple formula is:
Gross margin % = (Sell price − direct job cost) ÷ Sell price × 100
Use a consistent basis, such as prices excluding GST, and make sure the direct job cost contains the labour, materials, subcontractors, plant and other project costs you intend it to contain. Margin targets are business decisions; there is no single percentage that is correct for every contractor or every project.
20. Would another person understand the commercial deal?
Read the finished quote once without looking at your estimating notes. Could a supervisor, customer or another estimator understand what is included, what is excluded, what assumptions underpin the price and what could cause a variation? If not, the quote needs one more pass.
A five-minute pre-send review can be worth doing
The purpose of this checklist is not to make estimating bureaucratic. It is to put a control point between “the number looks about right” and “send”. The best time to find an omission is while the quote is still editable.
