How to compare commercial painting bids in Houston
By Juan Serra, owner, Houston Superior Painting ·
Commercial painting bids for the same building often differ because each contractor priced a different scope: different areas, prep, products, coats, hours or access. To compare them fairly, give every bidder the same written scope sheet, ask each to price it line by line with the products named, and compare exclusions and schedule as closely as the total. The lowest number is only a bargain if it covers the same work.
Why bids for the same building differ
- Measured areas. One bidder includes ceilings, doors and the stairwells; another prices walls only.
- Preparation. Patching, caulking, cleaning and spot priming can be a large share of the labor, or barely mentioned.
- Products and coats. A contractor-grade paint in one coat and a premium commercial line in two are different jobs.
- Hours and phasing. Nights and weekends, and working suite by suite around tenants, cost more than open daytime access.
- Access. Lifts, scaffolding and who supplies them can change the total noticeably.
- Protection and cleanup. Covering furniture, IT and flooring, and a clean handoff every morning, take time.
Level the bids with one scope sheet
Send every bidder the same written scope before the walkthrough. It should name:
- Areas and surfaces — rooms or suites, walls, ceilings, doors and frames, trim, stairwells, exterior elevations.
- Condition and prep — the repairs you know about, and the prep standard you expect.
- Products and colors — a product spec, or "match existing" with the colors and sheens listed.
- Coats or coverage standard — the number of coats, or uniform color and sheen with no patches showing.
- Work hours and phasing — business hours, after-hours, weekends, and which areas must stay open.
- Access and building rules — loading, elevators, parking, badges, and any lift or scaffold needs.
- Protection and cleanup — what must be covered and the daily handoff you expect.
- Insurance and documents — the certificate of insurance requirements, additional insured wording, and submittals.
The full proposal checklist is on our commercial painting cost per square foot guide.
Compare these side by side
| Line | What to check in each bid |
|---|---|
| Scope | Same areas and surfaces, or are some left out? |
| Prep | Is the repair and prep work described, or just "prep as needed"? |
| Products | Primer and finish named, with sheen and color schedule |
| Coats | Number of coats or a written coverage standard |
| Schedule | Start date, duration, work hours, phasing |
| Access | Lifts or scaffolding included, and who supplies them |
| Protection | What is covered, and the daily cleanup |
| Exclusions | What is not included, and how change orders are priced |
| Insurance | Can they meet your certificate of insurance requirements? |
| Warranty and terms | Written warranty and payment terms |
Red flags
- A single lump sum with no description of areas, prep or products.
- No product names, or "equal or better" with nothing to compare against.
- No coat count and no coverage standard.
- No exclusions listed: unknown items tend to come back as change orders.
- No written change-order process.
- Cannot provide the insurance documentation your building or property manager requires.
- Pressure to sign before you have compared the scope.
Questions to ask before you sign
- Who supervises the work on site, and who is my daily contact?
- How many people will be on site, and for how many days or nights?
- How will you keep the areas we use open and clean each morning?
- How do you match colors and sheen across suites painted on different days?
- What happens if you find damage behind the paint that isn't in the bid?
- What does the written warranty cover, and for how long?
Planning ranges
As planning ranges only, standard office walls may fall around $1.50–$3 per square foot of paintable wall area, retail interiors around $2–$4, and simple warehouse or shop walls around $0.75–$2. After-hours or weekend work often adds 15–30%. If one bid sits far outside the others, the scope is usually different; compare the lines above before the totals.
How we bid commercial work
We walk the space, measure it, and give a written proposal that lists the areas, prep, products, coats or coverage standard, work hours, protection and exclusions, so it can be compared line by line. Your written estimate identifies the complete scope, total price, required deposit and payment schedule before you approve the project. We carry $2M general liability plus workers' comp. A current certificate of insurance is available upon request and is provided after a project is approved, according to the project requirements.

Frequently asked questions
Why are commercial painting bids so different?
Usually because each contractor priced a different scope: different areas, prep, products, coats, work hours or access. Giving every bidder the same written scope sheet makes the bids comparable.
Should I take the lowest commercial painting bid?
Only if it covers the same scope. Compare areas, prep, named products, coats, schedule, exclusions and insurance line by line before comparing totals.
What should I send painters before they bid?
A written scope: the areas and surfaces, known repairs, products or colors, coats or a coverage standard, work hours and phasing, access and building rules, protection and cleanup, and your insurance requirements.
Does after-hours commercial painting cost more?
Usually. Night and weekend work often adds 15–30% to the labor, depending on the schedule and building rules.
When do I get a certificate of insurance?
A current certificate of insurance is available upon request and is provided after a project is approved, according to the project requirements.
