So why not just paint your own home. I'm not a painter, so my wife and I take our time, buying the paint and supplies, and doing our own painting. Yes, we need to tape, and it's not perfect, but we get the satisfaction of seeing our completed work. Get the supplies, sliders for your furniture, and patience and go for it. That way YOU have control over the entire project.
More recently, professional painters are responsible for all preparation prior to painting. All scraping, sanding, wallpaper removal, caulking, drywall or wood repair, patching, stain removal, filling nail holes or any defects with plaster or putty, cleaning, taping, preparation and priming are considered to be done by the professional contracted painter.
When coverage is difficult to estimate, add more rather than less when doing DIY wall painting. You can always pour the leftover back into cans. For large jobs, use the bucket and a roller screen rather than a roller tray. It’s much faster to load your roller with the screen than to use a roller pan. Simply dunk the roller into the paint bucket, then roll it along the screen until it stops dripping.
Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
When calculating total cost of your project, one of the most important factors to consider is the paint itself. Paint costs will be determined by the quantity of paint and primer required to complete your project, as well as the quality of the paint you choose. You can use this paint calculator to estimate how much paint you will need.. Once you have an idea what you're working with, go to your local home improvement store and compare the costs of a gallon in person. Painting professionals can also quote average prices from their years of experience working with different paint qualities.
Good contracts include descriptions of prep work and repairs; paint specs by brand name, type, color and product number; the number of coats; and a full description of the work, including frequently omitted items such as cabinet interiors and shutters. Minimize delays by specifying that, weather permitting, work will be continuous. Get a payment schedule that minimizes the down payment — the more payment you can withhold until the end, the more leverage you'll have to get the job done well and per your specifications. Insist that contractors provide proof that they carry both general liability and workers' compensation coverage.
Thanks, all, for your time & efforts adding to the article & comments, especially Dave urging requesting both General Liability AND Worker Compensation insurance certificates to protect from real & fraudulent liability--from my experience especially in California, where insurance fraud is a popular income thief, even causing car collisions to collect.
