We have done residential for four years. Ou general rule is $.95 per sq. ft. plus paint and any needed materials with a 40% mark-up.
We have been offerd the opportunty to bid on some commercial work; several stores being built-out in a shopping center. I'm told some painting contractors bid on the jobs using the sqaure fottage of the store times 'x', all inclusive. This is in Dallas, Texas.
Any thoughts, ideas, suggestions?
I would suggest purchasing the PDCA cost estimator or the National Paint Cost Estimator it automatically ads the price to the sf and substrate you should factor a 5% -20% overhead depending on the job.
