Plaster Wall Repair
Cracked, sagging horsehair plaster on ceilings and stair walls is the most common problem we find inside Montclair's early 1900s houses.
DetailsMontclair is a quiet grid of 1910s and 1920s two-families, bungalows and small Colonials between Wollaston and the Milton line, and the walls inside show their age with ceiling cracks, sagging plaster and doors that no longer close cleanly.

Montclair sits inland from the rest of the 02171 neighborhoods, west of Hancock Street and close to the Milton line, with West Squantum Street running through it. It feels more settled than the shore neighborhoods: smaller lots, mature street trees and a steady run of houses built in the years when the streetcar made the area a commuter suburb. Two-families share the blocks with Craftsman bungalows that have deep eaves and tapered porch columns, plus a scattering of small Colonials and later capes.
Inside nearly all of them is original plaster on wood lath. A century of settling, roof leaks, radiator heat and the occasional renovation has left long ceiling cracks, loose plaster over stairways and corners that have pulled away from the framing. That's why so many Montclair calls start with the walls rather than the paint color. We fix the plaster properly, then paint, and the finish lasts because the base under it is sound.

Plaster holds to wood lath by keys, the bits of plaster that squeezed between the lath strips when it was applied. Over decades those keys snap from settling, door slams and water damage, and the plaster begins to sag. Ceilings show it first, followed by the walls along the stairs. We reattach loose areas with plaster washers or adhesive injection, cut back cracks, bridge them with fiberglass mesh and setting compound, then skim and sand until the repair disappears under paint.
Small hairline cracks are cosmetic, but bulges, soft spots and cracks that keep reopening mean the plaster has let go of the lath. Painting over that only hides it for a season. Because almost every Montclair house predates 1978, we treat sanding and demolition as lead-safe work, with plastic containment, misting, HEPA vacuuming and a cleanup check.
Craftsman bungalows here have exposed rafter tails, wide eave boards, brackets and tapered columns, and those details peel first because they sit in the drip line. We scrape and sand each one, replace rotten rafter ends when needed and prime bare wood before two finish coats. A good share of Montclair two-families were covered in vinyl decades ago, with the wood trim still exposed. The vinyl can be cleaned and painted with a vinyl-safe color no darker than the original, and the wood trim gets proper scraping and priming.
We also see a lot of original wood storm windows and porch rails. Those can be stripped and repainted rather than replaced, which keeps the look of the street.
Most Montclair owners live in the house while we work, so we go room by room. Plaster repair goes first, because it needs drying time between coats of compound. While patches cure in one room, we prime and paint another. Furniture moves to the center under plastic, floors get covered and radiators are either masked or painted with a heat-resistant enamel. The staircase, often the most worn part of the house, usually comes last so the family can use it until the end.
On-street parking is tight on the narrow side streets, so we keep one vehicle on site and bring materials in for the week.

DetailsAfter plaster repair, full interior repaints in Montclair focus on trim-heavy rooms with original casings, baseboards and paneled doors.
DetailsWalls with years of patched cracks and old paper residue need a skim coat in Montclair houses before paint will look flat.
DetailsCast-iron radiators are still common in Montclair, and rusty or chipped ones look new again with a heat-resistant enamel.
DetailsClapboard bungalows and vinyl-covered two-families both need the right coating, color choice and prep for Montclair's freeze-thaw winters.
DetailsWorn treads, chipped balusters and grimy handrails on Montclair stairways are often the last unfinished part of an older house.

In most cases, yes. If the plaster still holds to the lath, or can be reattached with washers or adhesive, we repair it, skim it and paint it. Replacement only makes sense when large areas have fallen or the lath itself has failed. We test ceilings at the walk-through by pressing and tapping for movement.
Yes, if the vinyl is sound. We wash off chalk and mildew, then use a vinyl-safe paint in a color no darker than the original so the siding doesn't warp in summer sun. The wood trim on Montclair houses is scraped and primed separately, since it usually has older paint.
Some, but we control it. We tape plastic over doorways, cover floors and furniture, mist surfaces before scraping and use HEPA vacuums for cleanup. Since most Montclair houses are pre-1978 and presumed to contain lead paint, we finish each day with a cleanup check before you use the room again.
A typical planning range is $465 to $1,280 per room for crack repair, reattaching loose areas and a skim where needed, before paint. Ceilings with large sags or stairwells that need staging cost more. The walk-through sets the real number after we check how much plaster has let go.
