A commercial painting proposal should define scope by area and surface, prep, the coating system, schedule, exclusions, base bid with separate alternates, qualifications and terms, so buyers can compare it like for like.
Why commercial proposals are different
A residential quote can be one page with a price. A commercial proposal cannot. Property managers, facility directors and general contractors compare several bids, often weeks after the walk-through, and the proposal that is easiest to compare and hardest to misread usually wins.
The nine sections to include
| Section | What goes in it |
|---|---|
| 1. Project details | Project name, address, owner or GC, requester, walk-through date, proposal number and date. List the drawings, spec sections and addenda you priced. |
| 2. Scope by area and surface | Areas (elevations, corridors, units, stairwells, parking) and surfaces (CMU, stucco, drywall, doors and frames, steel, concrete), with quantities where you have them. |
| 3. Surface preparation | Pressure washing, scraping, sanding, caulking, patching, spot priming, rust treatment, stated per surface. |
| 4. Coating system | Primer and finish coats, product line or approved equal, sheen and number of coats per surface. Match a named spec or list your substitution. |
| 5. Schedule and conditions | Start, duration, work hours, phasing, night or weekend work, and how you protect occupants: signage, ventilation, low-VOC products, access. |
| 6. Exclusions and assumptions | Carpentry, drywall replacement beyond patching, lead abatement, special lifts, permits, moving furniture, color changes after approval; water and power access. |
| 7. Price | Base bid, then alternates and unit prices listed separately. |
| 8. Qualifications | Insurance limits, license, safety program, warranty and two or three similar commercial references; prevailing wage or bonding if required. |
| 9. Terms and acceptance | Payment schedule, retainage, change order pricing and approval, validity period and a signature block. |
Scope is where proposals win or lose
Vague scope (“paint the building”) causes most disputes and change orders. Specific scope also defends your price against a lower bid that quietly covers less. Prep gets the same scrutiny: experienced buyers read it closely because prep is where commercial coatings fail.
Keep alternates and unit prices out of the base bid. A buyer comparing three proposals needs one number that means the same thing in each.

Common questions
How long should a commercial painting proposal be?
Usually two to six pages plus attachments: long enough to define scope, prep, system, schedule and exclusions, short enough to compare in one sitting.
Should I show a price breakdown?
Show the base bid, alternates and unit prices. Many contractors do not itemize labor and material; buyers mainly want to see that the scope is complete.
How long should a proposal stay valid?
Thirty days is common. Shorten it when material prices are volatile.
