Interior Painting for Brighton, MA homeowners.

In ZIP code 02135, the Census puts the median year a housing unit was built at 1956, and 38.8% of units date from 1939 or earlier. That spread matters indoors. A room in a pre-war house may have original plaster, layers of old enamel on the window casings and a ceiling that has been painted many times over, while an apartment in a building finished after 2010 (11.9% of local units) is likely to have drywall and factory-primed trim. The prep for those two rooms is not the same job.

The sections below cover wall and ceiling repair, the lead rules that apply to older trim and doors, and how unit type affects scheduling.

Plaster, drywall and what lies under the paint

Plaster on wood or metal lath was the standard interior wall finish before drywall took over, so a pre-1940 interior may still have it. Plaster is hard and durable, but it cracks along ceiling joints and around door frames as a house moves, and loose plaster has to be secured before it is skimmed and primed. Painting over a crack without that step tends to let it reappear.

Ceilings deserve a separate look. Calcimine, an old water-based ceiling coating, can flake off in sheets when a modern latex goes over it; scraping a test patch tells you whether a ceiling needs a special sealing primer first. On drywall from later decades the common problems are smaller: nail pops, taped seams that show through flat paint, and gloss differences where earlier touch-ups were done.

• Hairline cracks in plaster: cut out, fill with setting compound, prime
• Loose or bulging plaster: re-attach to the lath before any finish work
• Flaking ceiling coating: test, then seal with a primer made for it
• Glossy old trim enamel: degrease, scuff, and bond-prime so new paint grips

Lead paint on doors, windows and trim

In the 02135 ZIP code, 74.1% of housing units were built in 1979 or earlier. The Census groups construction years by decade, so the exact pre-1978 share isn't published, but the figure shows how much of the local stock could carry lead paint under later coats. Friction surfaces such as window sashes, door edges and stair treads are where old paint wears into dust.

Under the federal EPA renovation rule, interior work in pre-1978 housing that disturbs more than six square feet of paint in a room must follow lead-safe practices. Scraping and sanding a full set of window casings can pass that line quickly. Our lead-safe painting page explains containment, cleanup and verification.

If abatement is needed rather than just safe repainting, the City of Boston's Lead Safe Boston program offers owners forgivable loans of up to $12,000 per unit, and a Letter of Compliance from a licensed lead inspector qualifies for a $3,000 Massachusetts tax credit. Income limits apply to owner-occupants of one- to four-family homes with a young child, so check the program page for eligibility.

Single rooms in a building, not a whole house

Only 9.2% of housing units in 02135 are detached single-family homes. Most local units sit in two-to-four-unit buildings (29.3%) or in buildings of five or more units (56.8%). For interior work, that means the job may be one condo or one floor of a two-family rather than a whole house. Before painters arrive, it helps to know your building's rules on work hours, elevator reservations, parking for a work vehicle and where materials can be staged.

Hallways and stairwells shared with other units are typically the association's responsibility rather than any one owner's. If your project touches them, get the board's approval in writing first.

Sequence for an occupied home

Ceilings go first, then walls, then trim and doors, so drips land on surfaces that haven't been finished yet. Furniture moves to the center and gets covered, floors get drop cloths taped at the edges, and switch plates come off. When older trim is involved and lead-safe work is required, the room is sealed with plastic and the cleanup is checked before you move back in.
