Hairline cracks in Bloomfield lath-and-plaster walls: what they usually mean

Not every crack in a Liberty Avenue–area house is a sign the wall is failing.

Bloomfield houses often still have lath and plaster, sometimes under later drywall. Hairline cracks at corners and over doors are common as old houses move a little. A tight, clean crack can often be repaired without opening the whole wall. A bulge, a hollow sound, or plaster that moves under a light hand is a different job.

Water stains are the exception you should not just paint. If a stain is growing, find the source first — a bath above, a roof edge, or a gutter overflow. Lawrenceville gutter repair is a short walk's worth of neighborhood away if rain is the suspect. An active pipe needs emergency leak help or a planned plumber, not a skim coat.

We will not claim a 'lifetime crack-free' plaster job in a house that still moves. We will tell you whether a patch, a larger re-attachment, or a drywall repair in a later wall is the honest scope.

Paint can wait until the repair is actually dry and primed. A same-day color match over damp plaster is how stains come back.
