What affects the cost of painting a house exterior, and why bids differ
The price of an exterior paint job follows the hours it takes. Here’s what drives those hours, why bids for one house can differ widely, and how to get an estimate that holds up.
Key takeaways
- Labor makes up most of a typical exterior bid, so the price follows the hours that size, height, access, condition and prep demand.
- Prep and repairs are usually the biggest variables, and they’re often why bids for the same house differ.
- Detailed trim, extra colors, big color changes and lead-safe work on pre-1978 homes all add hours, and Michigan’s short season limits the calendar.
- An accurate estimate starts with a close look at the whole house and a written scope covering prep, repairs, coats and product.
The cost of painting a house exterior follows the labor, and the labor follows four things: how big the house is, how hard it is to reach, what condition the surfaces are in, and how much prep they need. Paint matters, but on most homes it’s the smaller part of the bill.
Everything else, from trim detail to color changes, moves the price the same way: by adding or removing hours. Read a bid as a schedule of work and the gaps between painters start to make sense. Here’s where the hours come from on an exterior painting job.
How do size, height and access change the price?
Size means painted surface, not the square footage on a listing. A two-story house usually has more wall to cover than a ranch with the same floor space, and dormers, gables and bump-outs add more.
Height adds time on its own. Second-story walls, gable peaks and dormers mean tall extension ladders, standoffs to keep them off the gutters, and many more moves. Some walls call for a lift or scaffolding, which needs setup time, firm level ground and room to work.
Access is the ground those ladders stand on, and many houses don’t make it easy:
- Landscaping. Shrubs, beds and trees close to the walls have to be tied back and covered, and ladders have to work around them.
- Slopes. A steep grade or a walkout basement makes every setup slower and every ladder taller.
- Tight spots. Narrow side yards, fences, decks, porch roofs and air-conditioning units all slow the work.
How much do siding type and condition matter?
Siding sets the pace. Smooth wood clapboard goes relatively quickly. Cedar shingles and shakes have rough faces, deep edges and thirsty wood, so they take longer and drink more paint. Stucco and brick call for primers and paints suited to masonry, and aluminum siding, common on post-war homes, usually needs its chalky surface washed off so new paint can grip.
Condition matters even more. Paint that’s faded but sound mostly needs washing, light sanding and new coats. Paint that’s peeling, cracking or worn through to gray wood needs hours of scraping, sanding and priming first. Peeling usually has a cause, often moisture, and a careful painter looks for it before covering it up.
Why does prep vary so much from house to house?
Prep is usually the biggest variable in an exterior job, and the one most often cut short. Two bids that both say “scrape and prime” can describe very different amounts of work. Our guide to what thorough prep involves covers each step; these are the parts that move the hours:
- Scraping and sanding: removing every loose edge, then sanding the ridges so they don’t show through.
- Priming: spot-priming bare wood, or priming whole walls when much of the old paint is gone.
- Caulk: cutting out cracked caulk at trim joints, windows and doors, and replacing it over primer.
- Wood repair: rebuilding small soft spots with epoxy or exterior filler, or replacing rotted boards.
- Reglazing: replacing cracked putty on old wood windows; new putty has to firm up before it’s painted.
- Protection: covering plants, walks, roofs and patios, and collecting chips as the work goes.
Older houses usually need more of all of this, since decades of Michigan freeze–thaw cycles open joints, crack putty and let water into wood. If yours still has its original sashes, our guide to painting old wood windows explains why they take so long to do right.
Why do trim, windows and porches add up?
Walls are the fast part. Trim is where the brush slows down, because every edge is cut in by hand, often in a second color. Many of the period-revival homes around Grosse Pointe, from Colonial Revival to Tudor Revival, carry far more trim than a post-war ranch, and it shows up in the hours:
- Cornices and dentils. Every block in a dentil row has several faces to paint.
- Windows. Each one means casings, a sill and sashes; divided-light sashes, with muntins between the panes, multiply the brushwork.
- Shutters. Louvered shutters are slow, and they’re often taken down, painted separately and rehung.
- Porches. Columns, railings, balusters, beadboard ceilings and floors each take their own time, and sometimes their own products.
- Everything else. Paneled doors, garage doors, brackets, half-timbering, soffits and gutters, if they’re in the scope.
How do colors, coats and paint quality affect the price?
More colors
A single body color with white trim is the simplest job. Each added color, whether for shutters, a door, sashes or an accent, means more cutting in, more lines to keep crisp and more time switching between cans.
Big color changes
Repainting a similar color often covers well in two coats. A big change, such as deep brown to white or white to a saturated red, may need a primer, a tinted primer or an extra coat to cover evenly. Settle on colors before the bid, or at least tell each painter how big a change you’re considering, and test real samples on the house first, because chips and screens mislead.
Coats and product
One finish coat costs less up front than two, but two usually build a thicker, more even film that lasts longer. Better paint costs more per gallon, yet because labor makes up most of a typical bid, it adds less to the total than many people expect. We paint with Sherwin-Williams; whoever you hire, ask which product and how many coats the price includes.
What does lead-safe work add on older homes?
Homes built before 1978 may contain lead-based paint, and exterior prep is exactly the kind of work that disturbs it. The EPA’s Renovation, Repair and Painting (RRP) rule requires certified firms and lead-safe work practices for paid work that disturbs more than 20 square feet of painted surface outside a pre-1978 home, or more than 6 square feet per room inside. The EPA’s RRP program page has the details.
Those practices take time and materials: plastic sheeting to catch chips, limits on how old paint can be removed, and thorough cleanup. On a large older house with a lot of failing paint, that’s a real part of the job, and a bid for a pre-1978 home that never mentions it deserves a question. Our guide to lead paint in older homes goes further.
How do the season and surprise repairs affect cost?
Michigan’s exterior season is short, roughly late spring to early fall, and painters’ calendars often fill early. Rain, heavy dew and cold nights all cost painting days, and paint applied outside the label’s temperature and moisture limits may not adhere or cure properly. Where a lift or scaffolding is rented, a longer schedule can mean a longer rental. Our guide to when to paint an exterior in Michigan covers timing in detail.
The other unknown is what turns up once scraping starts. Rot hides under sound-looking paint, behind gutters and at the ends of sills and trim boards. A good estimate flags the risks it can see and spells out how hidden repairs will be handled: who decides, how they’re priced, and whether work waits for your approval.
Why do bids for the same house differ so much?
Usually because they describe different jobs. One painter prices thorough scraping, priming, new caulk and two finish coats; another prices one coat after a quick wash. One includes gutters, shutters and window sashes; another leaves them out without saying so. One plans for lead-safe work on an older home; another never mentions it.
Some gaps are honest differences of judgment about condition. Others are a low number that grows later through change orders. Line up the written scopes before you compare totals; our guide to comparing painting estimates shows what to check.
How to get an accurate estimate
Whether you request an estimate from us or another painter, an accurate number starts with a close look at the house:
- Walk the whole house: back and sides included, with a close look at second-story trim and windows.
- Share what you know: soft wood, leaks, the worst peeling, the year the house was built and any lead test results.
- Define the scope: which items are in or out, such as gutters, shutters, doors, porch floors and windows, and how many colors.
- Get it in writing: prep steps, repairs, primer, number of coats, product, and how hidden damage will be handled.
A painter who quotes from the driveway is guessing, and guesses tend to show up later as change orders or skipped prep.
Questions
Why do painting bids for the same house differ so much?
Usually because they describe different jobs. One bid may include thorough scraping, priming, new caulk, repairs and two finish coats, while another covers one coat over light prep and leaves out shutters or gutters. Compare the written scopes line by line before comparing totals.
Does better paint make exterior painting much more expensive?
Usually not by as much as people expect. Labor makes up most of a typical exterior bid, so better paint adds comparatively little to the total, and it can help the finish last longer. Ask each painter which product and how many coats their price includes.
Does the time of year affect the cost of exterior painting?
It can, mostly through scheduling and weather. Michigan’s exterior season is short, roughly late spring to early fall, so calendars fill and rain, dew and cold nights can stretch a job. Paint applied outside the label’s temperature and moisture limits may not adhere or cure properly, and redoing it costs more than waiting.
