Walls, ceilings, trim, doors and stairways painted with the prep each room's age calls for, from prewar plaster to recent drywall.
Census figures put the median construction year of the town's housing at 1964, and 70.8% of its units were built before 1980. Before a brush touches a wall, that date matters for two reasons: the materials under the paint, and the chance that some of those old coats contain lead, which federal rules tie to homes built before 1978.
About one unit in five (21.7%) dates to 1939 or earlier. Another large block arrived after World War II. The town master plan records roughly 21,000 new residents between 1945 and 1960, and the 1950s are the biggest single decade in the Census count, at 16.3% of units.
Prewar interiors were commonly finished in plaster over lath. Plaster gives a hard, dense surface, but over decades it develops hairline cracks, nail pops where the lath has shifted, and soft or bulging spots where the plaster keys have let go. Fine cracks can be opened up and filled; a loose section has to be reattached with plaster washers or patched before paint goes on, or the crack shows through again within a season.
Drywall in later houses brings different flaws: lifted tape at the seams, screw pops, and patches that flash through a flat finish because they absorb paint differently from the paper around them. Spot priming every repair is what keeps the sheen even across a wall. Plenty of houses have both surfaces, where an addition or a finished basement meets the original rooms.
The old coating matters as much as the wall. If the trim was last painted with an oil-based product, latex applied straight over it can peel off in strips. A cotton swab dampened with denatured alcohol tells you which you have: latex softens and rubs off onto the swab, oil does not. The latex vs. oil comparison explains the bonding primer step that bridges the two.
Any home built before 1978 may have lead paint beneath newer layers, most often on windows, doors, stair parts and trim, where friction wears through to the bottom coats. Sanding or scraping those surfaces makes fine dust that settles on floors and windowsills, where children and pets pick it up.
Federal and Massachusetts renovation rules require lead-safe work practices for paid jobs that disturb more than 6 square feet of painted surface per room in a pre-1978 home. In practice that means plastic sheeting, misting instead of dry sanding, HEPA vacuums and a cleaning check before the room is handed back. The lead-safe painting page covers what the rules require and what to ask a contractor before work starts.
Ceilings in older rooms can carry calcimine or decades-old water stains that bleed through fresh latex as yellow rings. A stain-blocking primer stops them coming back. Stairwells are tall and narrow, so they need a plank or stair ladder rather than a stepladder, and they are best painted after furniture has finished moving up and down them.
Trim tells you the era. The Historical Commission's demolition delay list includes houses in Federal, Greek Revival, Italianate, Queen Anne, Colonial Revival and Bungalow styles, and original casings and moldings in houses like these can hold so many coats that the profiles have gone soft. Careful scraping and sanding brings back definition. Stripping to bare wood is a much larger job and, where lead is present, a regulated one.
Indoor work isn't tied to the weather, so it fits the months when outdoor painting stops. Air and temperature still count: heated winter air dries paint quickly, and a cold room against an uninsulated wall can slow curing. The post on winter interior painting covers ventilation and drying during the heating season.

The repair is to open the crack slightly, bed mesh tape in a setting-type compound and feather it out before priming. If the plaster flexes when you press it, it has to be re-secured first.
A house from that decade predates the 1978 federal ban on lead paint for homes, so it's possible, particularly on original windows and trim. A licensed inspector or risk assessor can test the surfaces, and EPA-recognized test kits give a quicker answer for a specific spot. Without a test, plan the work as if lead is there.
It can. Plaster and drywall soak up paint at different rates, and drywall paper can look duller under the same sheen. Priming the drywall and using one sheen throughout evens them out, and a matte finish hides the texture difference best.
Yes, in most cases. The work can be sequenced so you keep a usable bedroom, bathroom and kitchen, with furniture pushed to the center of each room and covered. Low-odor waterborne paints let a finished room go back into use the same evening.
Not always. Sound trim in a color you like can wait. But oil-based trim paint yellows with age, and chipped door edges and windowsills in an older house can be a lead concern, so it's worth looking at both before deciding.
The number of rooms matters less than ceiling height, the amount of plaster repair, how much trim and how many doors there are, and whether lead-safe setup is needed.
