Every argument about paint quality is really an argument about prep. Two crews can put the same coating on the same wall and get results that diverge sharply, and the difference was decided before either of them opened a can. Washing, scraping, sanding, caulking, patching and priming are the majority of the labor in a good paint job, they become invisible the moment the finish goes on, and they are the first line cut when a bid needs to be the cheap one.
Prep is also diagnostic. Failing paint tells you why it failed, provided somebody reads it. Peeling in sheets points to moisture or an adhesion problem underneath. Chalking points to age and UV. Failure concentrated at joints and edges points somewhere else again. Prep done properly starts with working out what went wrong last time, because whatever coating goes on next will fail the same way if the cause is still sitting there.
Before anything is removed, somebody reads the failure pattern: sheets versus flakes, chalk versus cracks, worst at the top or worst near the ground. That reading sets the plan for everything after it.
Wash the surfaces, then scrape back to material that is genuinely sound. On homes built before 1978 this is also where lead-safe practices enter the picture, because dust and debris are the issue.
Holes and dings get filled, caulk lines get cut out and replaced where they have failed, and everything gets sanded flat so the repairs disappear under the finish instead of announcing themselves.
Each substrate gets the primer its condition calls for: sealing porous areas, blocking stains, promoting adhesion on slick spots, binding chalky ones. Then, and only then, is the surface ready for color.
Prep is the line item that makes two quotes for the same house look unrelated to each other. The main driver is condition: paint that is intact and needs cleaning and a light sanding versus a surface with widespread failure that has to be scraped back, feathered and primed section by section. After that come square footage and reach, since staging and ladder time apply to prep exactly as they apply to coating; the number of different surfaces and materials involved, because each one needs its own primer approach; how much trim, detail and caulk work is in play; and, on older homes, whether lead-safe work practices are required.
Look for verbs, not adjectives. Washing, scraping, sanding, caulking, patching and priming are things somebody does for hours. A quote that names those steps and says which surfaces get them is describing where the labor went. A quote that goes straight to product and color has left the largest part of the job undescribed, which is worth one direct question in writing.
Homes built before 1978 may contain lead-based paint, and that changes how those surfaces can legally be disturbed. Since prep is largely about disturbing surfaces through scraping, sanding and heat, this affects the plan, the containment and the cleanup. Testing and lead-safe practices should come up during the estimate, not after somebody has already started sanding.
No, and blanket priming can be a waste. Primer is a targeted product: sealing porous surfaces, blocking stains and tannins, promoting adhesion on slick areas, binding chalky ones. Bare wood, stucco, brick, patched spots and sound existing paint all get different answers. What matters is that somebody can tell you which surfaces they expect to prime and why.
Yes, though the method depends on the surface. The point is to remove chalk, dust, pollen, grease and anything else that stops the coating from bonding, and then to let the surface dry properly before anything goes over it. Painting a clean wet surface can cause the same failures as painting a dry dirty one, so the drying part is not a delay to negotiate away.
Walls, ceilings, trim and doors, plus the patching and caulking that decides whether the finished room reads smooth or shows every old nail pop. Inside the house, sheen matters as much as color, because sheen is what you touch and wash.
