Why nobody can give you a number over the phone
Every painting company is asked for a ballpark before anyone has seen the house, and the honest answer is that a ballpark given over the phone is worth nothing to you. Not because it is a secret, but because the same 1,900 square feet is a three-day job or a three-week job depending on things that cannot be described down a phone line. Here is what those things are, in the order they matter.
| Work | Priced on | The question that moves it most |
|---|---|---|
| Interior painting | Rooms, surfaces, and ceiling height | Are ceilings in scope, and how tall are they? |
| Exterior painting | Elevations, substrate, and prep hours | What percentage of the surface has to be scraped? |
| Cabinet refinishing | Count of doors and drawer fronts | Does open-grain oak need filling for a smooth finish? |
| Popcorn ceiling removal | Room area, plus skim and finish | Is skim coating and painting included, or scrape only? |
| Drywall repair | Size, ceiling vs wall, texture match | How hard is the existing texture to disappear into? |
| Deck staining | Linear feet of railing more than floor area | How much rail and baluster is there? |
| House soft washing | Elevation size and mildew load | Is it a standalone wash or prep for a repaint? |
Why two quotes on the same house differ by thousands
This is the question everyone actually has, and the answer is almost never that one contractor is greedy. It is that they scoped different work.
Take two bids on the same 1962 Monona ranch with cedar siding that is twelve years past due, one of them nearly double the other. The cheaper bid is a wash and two coats. The higher bid is a wash, hand-scraping roughly 40% of the surface, feather-sanding the transitions, priming all bare wood the same day it is exposed, replacing two rotted trim boards, and then two coats.
Both are honest descriptions of work. Only one of them is still on the house in year eight. The cheaper bid is not cheaper, it is a partial job priced as a whole one, and the failure will show up on the south wall first. Nothing about the two totals tells you that — only the scope does.
The seven things that move a painting price
1. Condition, not size
Up to 40% of an exterior price is prep. Scraping, sanding, and priming bare wood is slow, skilled, unglamorous work that does not photograph well and is the entire reason a finish lasts. Two identical Madison colonials can be thousands of dollars apart on prep alone, with nothing visible from the street to explain it.
2. Ceiling height
A room with 9-foot ceilings has about 12% more wall than the same footprint at 8 feet, and a two-story foyer needs staging that a bedroom does not. Height is the cost nobody accounts for when they estimate off a floor plan.
3. Color change
Dark to light is a three-coat job. Deep saturated colors, especially reds and navies, have tint bases with very little hiding power and often need three coats over any substrate. Beige to a slightly different beige is two coats. This is a real cost difference, not a markup.
4. Trim, doors, and windows
Trim is the slowest square footage on any job because it is cut by hand. A room with six-panel doors, wide baseboard, crown molding, and divided-light windows can cost more to paint than the walls it surrounds.
5. Pre-1978 construction
Roughly half of Madison's housing predates 1978. Paid work that disturbs paint in those homes falls under the EPA Renovation, Repair and Painting rule, which requires a certified firm, contained work areas, and specific cleanup. That is a real line item. A contractor who does not mention it on your 1955 house is either uncertified or cutting a legal corner, and both should concern you.
6. Product grade
The gap between builder-grade wall paint and a top-line acrylic is a modest amount per gallon and about four years of service life. On a Wisconsin exterior, the cheap gallon is the expensive choice. On a low-traffic ceiling, it genuinely does not matter, and a good contractor will tell you which is which.
7. Season
Exterior work in Wisconsin has a roughly 20-week window. May and September book out first. Interior work in January is easier to schedule, and it is the one time of year that flexibility actually helps your position.
Why per-square-foot pricing is mostly a myth
Homeowners ask for a per-square-foot number because it feels comparable, and contractors give one because refusing sounds evasive. But the number is derived, not primary. A price is calculated from surfaces, prep hours, height, coats, and materials, and any per-square-foot figure is worked out afterward. Running it the other direction gets you a number that is wrong in a specific direction: too low on old houses and too high on new ones.
So treat any per-foot figure you are quoted as a description of that contractor’s assumptions rather than as a price, and ask what those assumptions were. The answer is more useful than the rate.
How to get a number you can rely on
- Get three written, itemized estimates. Not verbal, not a single total, itemized by surface and by prep.
- Ask each one what percentage of the exterior they will scrape and why.
- Ask how many coats, and what happens if the color does not cover in two.
- Ask whether the crew is employees or subcontractors, and who is on site each day.
- Ask for the certificate of insurance directly from the insurer, not a photocopy.
- For any pre-1978 home, ask for the EPA lead-safe firm certification number.
- Throw out the lowest bid if it is far below the others. It is not a deal, it is a different scope.
