Paint supplies cost anywhere from $10 to $100 or more depending on what you need. Painters will typically provide most of the supplies for a project, but sometimes they will allow you to pay for solely labor if you provide all the materials yourself. You might decide to do a DIY paint job down the road. In which case having these supplies on-hand will save you time and money.
Most of a projects price is the cost of labor at $25 to $75 per hour. However, most contractors bid out based on the entire project which includes all work hours. Hourly rates are only useful if your pro asks to do the job as “time and materials.” However, be wary of this pricing structure, it usually shows the contractor is uncertain how long the project will take.
