What Should a Commercial Exterior Painting Quote Include?
You open three quotes for the same building. The numbers are $19,400, $26,800, and $34,200. All three say "exterior painting." One is a single paragraph with a price at the bottom. You're supposed to pick the right one.
The price gap isn't what you should be staring at. The real question is whether these quotes are even describing the same job.
Why commercial painting quotes are so hard to compare
Commercial painting is one of those trades where the price can vary by 40 percent between two legitimate contractors — and the difference often isn't the work. It's the scope.
A quote that says "paint all exterior surfaces" covers roughly the same physical footprint as one that says "apply one coat of Sherwin-Williams Resilience satin to all field surfaces, two coats of semi-gloss to trim and fascia, including full spot priming at bare wood and caulking all window and door perimeters." Those aren't the same job. The first one is going to look painted. The second one holds up.
The contractor who wrote the vague quote might do excellent work. They also might not. You have no way to know from the paperwork. And if the job goes wrong at the 18-month mark, you have no written record of what was supposed to happen.
That's the real problem with thin quotes: they protect the contractor, not you.
What the scope-of-work section should name
A commercial exterior painting quote should describe the work in enough detail that a different crew could pick up the document and know exactly what to do. Not roughly. Exactly.
At a minimum, the scope section should cover:
| Scope item | What to look for | Red flag |
|---|---|---|
| Surfaces included | Field siding, trim, fascia, soffits, doors, windows named individually | "All exterior surfaces" with no list |
| Surfaces excluded | Any surface not in scope explicitly named | Silence — assumes everything is included |
| Prep work | Pressure washing PSI, scraping locations, caulk, primer — in writing | "As needed" or no prep detail at all |
| Paint spec | Brand, product line, sheen, coats per surface type | "Premium exterior paint" with nothing else |
| Access equipment | Scaffolding or lifts named and costed as a line item | Access costs folded into a per-sq-ft number |
| Cleanup | Daily protocol, debris removal, masking of adjacent surfaces | No mention |
An $18,000 quote that doesn't name the prep work isn't cheaper than a $26,000 quote that does. It's just incomplete.
Surface prep is where cheap quotes actually save money
Labor runs 70 to 80 percent of the cost of a commercial painting project. Surface prep is a large portion of that labor. It's also the section most likely to be cut from a low-bid quote — because once the finish coat goes on, nobody can tell what happened underneath.
A bare spot that wasn't primed. A joint that wasn't recaulked. A section of fascia that got pressure washed but not scraped. None of these show up on completion day. They show up 18 months later as peeling paint, water behind the siding, or bubbling along the seam.
A serious quote names the prep steps by surface. Pressure washing should specify PSI — 1,500 to 2,500 PSI is typical for most commercial siding, with softer substrates running lower. "Clean exterior" is not a prep spec. Scraping and sanding should name locations, not say "as needed." Caulking should appear as a named line item at window perimeters, door frames, penetrations, and horizontal surfaces that hold water.
Priming matters more than most quotes acknowledge. Bare wood, metal, repaired areas, and surfaces with previous stain each require a different primer type. A quote that skips primer and jumps to finish coat is assuming every surface on that building is in perfect condition. Few commercial buildings are.
Think of prep like the adhesive on a bandage. The bandage doesn't fail at the dressing — it fails at the edge where the adhesion was weakest.
Paint specs belong in writing, not in a conversation
"Premium exterior paint" is not a spec. It's a promise that nobody can hold anyone to.
A quote that means something names the product: Sherwin-Williams Duration, Sherwin-Williams Resilience, Benjamin Moore Aura Exterior. These are real product lines with data sheets, coverage rates, and manufacturer warranty terms attached. If a contractor substitutes a discounted product after the contract is signed — and the quote only said "premium exterior" — you have no recourse.
The paint spec section should include the brand and product line for the field coat, the brand and product for the primer, the number of coats per surface type, and the sheen on field surfaces, trim, and doors separately. Two coats over sound existing paint is a different coverage calculation than two coats over bare or freshly primed surfaces. That difference affects both the final price and how long the job holds.
Scheduling, lifts, and what happens when the weather doesn't cooperate
Commercial exterior painting doesn't run on the same tight schedule as interior work. A 20,000-square-foot building is logistically complex — boom lifts or scaffolding, multiple crews, and coordination with tenants who need access to the building while work is happening.
The timeline section of the quote should name the projected start date, estimated completion, and how weather delays get handled. Freeze-thaw cycles running October through March make exterior painting windows narrow. A job starting in late September needs a weather-delay clause in writing, not a verbal assurance that "we'll work around it."
Work hours matter for occupied buildings. A crew on scaffolding at the main entrance during business hours disrupts operations. The quote should name planned working hours and any access restrictions negotiated in advance.
Scaffolding and lift costs belong as a named line item — not folded silently into a per-square-foot rate. A boom lift on a 30-foot wall runs $500 to $1,500 per day. That's a real number that belongs on paper.
One line item many quotes skip: mobilization fees. Some contractors charge a flat fee for hauling lifts, scaffolding, and heavy equipment to the site. Ask whether that's included in the overall price before you sign anything.
Payment terms, change orders, and what happens when scope shifts
Standard commercial painting payment runs 30 to 40 percent upfront as a deposit, with the balance due at completion. Some contractors bill in milestones — deposit, 50 percent at project midpoint, and balance on completion. Either structure is normal.
A request for 75 percent or more before work begins is worth pausing on. Not because the contractor is necessarily dishonest, but once that money changes hands, you've lost your position if the job stalls or if quality issues surface in the second half of the project.
The quote should also state the change order process. Commercial buildings run into surprises — more deteriorated wood behind the fascia than the site visit revealed, or the owner decides to add a second outbuilding mid-project. A legitimate contractor issues a written change order with the revised price and timeline before any out-of-scope work begins. A verbal agreement about a scope addition is the beginning of a dispute.
The warranty: what it covers and what it doesn't
Most commercial painting warranties run one to three years. A one-year warranty covers application defects — paint that peels, bubbles, or fails under normal conditions in the first year. A three-year warranty signals the contractor stands behind their prep work and product spec enough to commit to a longer window.
Warranties don't cover substrate damage. If the wood under the paint rots, that's a structural issue, not a paint issue. Storm damage, surface modifications, and pressure washing the building after completion can also void coverage. Read the actual language, not just the number of years.
The warranty statement belongs in the quote as a written clause — what it covers, how long it runs, and what voids it. A verbal warranty is worth nothing if the contractor disputes a claim a year and a half later.
What the insurance certificate needs to say
Not "we're insured." The actual document.
A Certificate of Insurance is a one-page form issued by the contractor's carrier listing policy numbers, coverage amounts, and effective dates. For commercial painting, you want to see general liability at a minimum of $1 million per occurrence and $2 million aggregate — standard floors for most commercial projects. Workers' compensation should cover the full crew. If a worker gets hurt on your property and the contractor is carrying no workers' comp, that exposure lands on you.
Ask to be named as an additional insured on the policy. That means if a claim arises from work on your building, your property is covered under the contractor's policy, not just the contractor's company.
A certificate from an expired policy is the same as no coverage. Check the dates before work starts.
Frequently Asked Questions
A legitimate commercial quote requires a site visit before any number goes on paper. Expect one to three business days after the site visit for the written document to arrive. A quote issued within hours of a phone call — without anyone walking the building — is a rough number, not a quote.
Contractors often price commercial exterior painting at $2 to $6 per square foot of paintable surface area. That range is wide because surface condition, story height, substrate type, prep scope, and paint spec all change the math. A per-square-foot rate with no scope breakdown tells you very little.
Most commercial exterior projects call for two coats of finish paint over properly primed surfaces. Single-coat applications work on recently painted surfaces in excellent condition. Three coats come up when covering a dark color with a significantly lighter one, or when the contractor specs a product line with a longer manufacturer warranty.
An estimate is a rough number based on a description or photos. A quote is a written, binding scope of work with a final price, paint spec, timeline, warranty, and payment terms. Before signing anything, confirm you have a quote — not an estimate — with all the detail in writing.
In most commercial quotes, prep labor is rolled into the overall price rather than broken out as a separate line. What matters is whether the prep steps are described specifically enough that you know what's included. A quote that says "pressure wash, scrape, spot prime, and caulk all window perimeters" tells you something. A quote that says "prep surfaces as needed" tells you nothing.
Ask both contractors for a line-by-line breakdown. The difference almost always comes down to prep scope, paint spec, or warranty terms. A $15,000 gap between two legitimate bids typically means one is spec'ing two coats of a premium product over full prep with a three-year warranty, and the other is spec'ing one coat over minimal prep. Or the cheaper quote has excluded something the other one includes.
Reading quotes on the same terms
The only way to compare commercial painting bids fairly is to hold each one to the same checklist. When one quote names prep work and another doesn't, you're not looking at two prices for the same job. You're looking at two different jobs with different prices — and the cheaper one is probably the more expensive one in the end.
Ask every contractor to match the same scope-of-work format before you finalize your comparison. Any contractor who resists putting that detail in writing is telling you something about how they plan to run the project.
