Historically, the painter was responsible for the mixing of the paint; keeping a ready supply of pigments, oils, thinners and driers. The painter would use his experience to determine a suitable mixture depending on the nature of the job. In modern times, the painter is primarily responsible for preparation of the surface to be painted, such as patching holes in drywall, using masking tape and other protection on surfaces not to be painted, applying the paint and then cleaning up.
OF the different type of customers there are at least two: cheap charley's and people who want great results. I agree the need for wall repair is critical to the end results. Most critical is for the customer to be told ahead that the walls are going to need exactly what is needed. This means the contractor must look, touch, examine the walls for defects and needed work. I've been a building manager for 40 years and seen a few paint jobs. Typically a contractor does a lot of talking about how expert he is, but the guys who walk through with note pads, iPads, examine, measure, point things out, explain and recommend are the ones I will deal with. It confirms if they know what the business. Nobody likes the workers to show up and when you talk about the job they're going to do they know nothing but they we were told to be here. Their boss who bid the job doesn't supervise - a big no no around here. Nobody likes surprises or worse, at the end of a job that's not right getting a bunch of little kid excuses. Contractors that do not like the customer to be around looking at the progress don't get the job.
Next, undercut the trim to create a gap (Photo 3). When you’re done, scrape any dirt or gunk out of the gap with a putty knife and blow out the dust using a vacuum or air compressor. To avoid staining the concrete, run at least three layers of masking tape under the wood. Apply repellent to all bare wood (Photo 4) including the underside (Photo 5). Bend a putty knife in a vise to make a handy tool for reaching into tight areas. Remove the tape right after application.
I turn away any job when the client refuses to pay anything up front. It sends a red flag. I also charge a scheduling fee which is non-refundable. I get 33 percent when I show up and begin work. Another percentage halfway through, and the balance upon completion after client is satisfied. There needs to be skin in the game for both parties as a measure of good faith. If you are dealing with a reputable company (did your due diligence, right?) why wouldn't you want to pay something as work progresses? We do this not only because we love to paint but we require cash flow to stay in business. There is not always 'money in the bank' as you suggest. It's tough these days. The suggestion buy 'Kim' 'Never pay a contractor a deposit' is nonsensical.
I used to work at Sherwin Williams. The best thing to do is specify that you will purchase your own paint. If the painter objects strenuously, he was plaanning on making money in the ways this article outlines. You might pay a few dollars more for paint, but you will have control of the quality of what goes on your walls. Never skimp on paint quality.
