Commercial work pays when the scope is written and kills you when the scope is a hallway conversation. General contractors, property managers, and facility directors compare line items, insurance certificates, and past performance.
Residential speed does not transfer. You need a bid sheet, a walkthrough habit, and a clear no when the job fits someone else.
This guide covers how to bid commercial painting jobs without inventing numbers: walkthroughs, takeoffs tied to drawings or field measurements, prevailing wage and insurance questions, and repaint programs. Turn measured square feet and hours through the painting estimate calculator the same way you would on a house, with production rates you logged yourself.
Dollar pricing methods sit in how to price a painting job. Exterior takeoff steps sit in how to measure a house for exterior painting.
Before you walk the site
Read the bid invitation twice. Note due date, submission format, bond requirements, and whether the owner expects unit prices or one lump sum.
Confirm you can meet insurance limits. Many schools and hospitals ask for general liability, auto, workers comp, and umbrella amounts your broker must verify. If you cannot certificate the limits, pass early and save estimating labor.
Ask whether the job is prevailing wage or Davis Bacon. Wage determinations change loaded labor lines. Your residential hourly rate is not safe to paste into a public works sheet without checking classifications.
Print a blank bid sheet or open your spreadsheet before you leave the truck. Empty boxes on site turn into guesses at the kitchen table.
The walkthrough: what to capture
Walk with the decision maker or the GC superintendent. Record ceiling heights, floor counts, occupied versus vacant areas, and hours the building allows work.
Surfaces: walls, ceilings, columns, doors, frames, railings, and any specialty coatings called out.
Prep level: wash only, patch and sand, lead or asbestos assumptions, who abates if found.
Access: lifts, swing stages, night work, furniture movement, and whether other trades are in your way.
Schedule: phased areas, weekends only, dry time between coats in cold warehouses.
Take photos with date stamps. Sketch floor plates when no drawings exist. Count doors and frames instead of guessing “about forty.”
GotLocal’s commercial painter website pages explain what property managers look for online before they invite bidders. Your bid should match the professionalism those pages describe.
Build the bid sheet from scope, not from hope
Split labor, materials, equipment, and subcontractor lines the way the customer asked. Hide nothing in one “paint package” line unless the RFP allows it.
Labor: hours per phase times loaded rate. Use production logging from painting production rates. Commercial open ceilings often run slower than residential rooms.
Materials: gallons from sq ft, coat count, and 350 sq ft per gallon coverage unless the spec names a product with different spread rate. Add caulk, patch, and primer lines.
Equipment: lifts, sprayers, containment, and floor protection with rental days.
Subcontractors: abatement, drywall, or signage removal if you are not doing them.
Add contingency only where you document risk. “Misc” without hours is how you eat change orders for free.
Worked example: small office repaint (one floor)
This example is bid math only, not a market price. Assumptions: 4,000 sq ft open office, 10 foot ceilings, walls only two coats, light patch, no after hours, two painters, production 120 sq ft per hour on walls (same calculator exterior default as a placeholder until you log commercial walls).
Paintable walls: measured 4,800 sq ft after subtracting glass partitions counted as not painted (your walkthrough notes list 600 sq ft glass).
Hours: two coats rolling 4,800 × 2 ÷ 120 = 80 hours. Add 8 hours patch and mask. Total 88 crew hours.
Labor cost at your loaded rate: if your shop uses $55 per hour in the calculator as a placeholder, labor = 88 × 55 = $4,840. Replace the rate with your loaded commercial number before you submit.
Materials: gallons = ceiling(4,800 × 2 ÷ 350) = 28 gallons. At $45 per gallon placeholder = $1,260 paint before markup lines.
Markup and margin: run the same subtotal and margin math as residential in how to price a painting job. Add lift or night shift lines if the walkthrough requires them.
A real office bid adds ceilings, doors, restroom ceramics boundaries, occupied phasing, and spec products. This sheet shows how sq ft flows to hours without skipping the walkthrough list.
Prevailing wage and certified payroll
Public jobs attach wage rates to classifications such as painter or drywall finisher. Your bid labor lines must use those rates plus fringes.
Ask the awarding body for the wage determination early. Build a separate column in your sheet so you do not mix private and public numbers.
Certified payroll reporting is administrative hours. Some owners include a small line for compliance time.
Others raise loaded rate. Either way, name it in your notes.
Insurance, COI, and additional insured
Never start work without a certificate that matches the contract. Additional insured endorsements can take days with your broker.
Read hold harmless language. Some contracts push liability beyond what your policy allows. That is a pass signal unless your attorney and broker agree.
Keep COI and W9 packets ready in a folder. Commercial buyers choose bidders who answer the same day.
Repaint programs and multi year work
Property managers sometimes award three year repaint cycles instead of one big job. Bid year one with clear sq ft caps and escalation for years two and three.
Define what triggers extra billing: new tenants, damage, or color changes outside the program. Log production on year one jobs so year two bids get sharper when you are not guessing the same buildings again.
When to walk away
Pass when scope keeps shifting in email, when insurance limits exceed your policy, or when the schedule requires crew sizes you do not have. Pass when the customer wants your price to match a residential sq ft habit on a warehouse with lifts and night shifts. A no today is cheaper than a crew month at a loss.
FAQ
Do I need different website pages for commercial work?
You need clear commercial pages on the same domain. GotLocal covers that in the commercial painter website section on /for/painters.
Should I use hourly or square foot pricing on commercial bids?
Many GCs want unit prices on drawings and hourly on unknown prep. Use the method the RFP asks for, built from the same hour logs.
How do I handle occupied buildings?
Phase the takeoff by area. Add hours for moving furniture, nightly reset, and signage protection.
Where do I practice gallons and hours math?
The painting estimate calculator in sq ft mode with your production and prep fields. Run the same numbers you used on the walkthrough before you submit.
What about lead and asbestos?
Stop and specify abatement by a licensed sub. Do not bury abatement hours inside paint labor without a line item.
Next step for your business
Commercial bids reward painters who measure, document, and look established online. Pair sharp estimating with commercial pages that match how GCs search.
