I can’t stress enough how important prep is to an exterior paint job. “Prep” is a term we use to refer to the preparation of the surfaces that will be painted. It could include detailed mildew treatment, power washing, scraping, sanding, feather sanding, priming, caulking, puttying, and more. These steps will determine if your paint job is set up to succeed or fail, in both the short and long term. Make sure the proposal you receive explains in detail the type of prep you will receive as part of the job.
