Older homes reward careful preparation. Here is what should be evaluated before sanding, scraping or covering historic surfaces.
Begin with the building, not the color
Older homes often contain several generations of repairs and coatings. Before choosing paint, inspect active moisture, cracked plaster, failing caulk, loose trim and surfaces that rub or move.
New paint can make a sound surface beautiful; it cannot permanently solve a leak, unstable plaster or decayed wood.
Pre-1978 paint requires special attention
Renovation, repair and painting that disturbs painted surfaces in many pre-1978 homes may be subject to lead-safe requirements. The EPA explains that paid firms performing covered work generally must be certified and use lead-safe practices.
Homeowners should determine the building age and discuss testing or lead-safe procedures before sanding, scraping, demolition or window and trim work begins. This article is general information, not a substitute for a project-specific regulatory determination.
Plaster and historic trim
A plaster crack can be cosmetic or evidence of movement. Repairs should be stable, feathered and primed so the finish does not flash. Historic trim may have profiles that are difficult to replace, making careful repair more appropriate than removal.
Doors and windows also create friction surfaces. Thick layers of paint can interfere with operation and may require a different scope than ordinary wall painting.
- Roof or plumbing moisture
- Loose plaster and recurring cracks
- Peeling or alligatoring coatings
- Soft exterior wood
- Window and door friction points
- Unknown coatings on pre-1978 surfaces
Local housing context
Wakefield, Lexington and Melrose include many older houses with plaster, detailed casing, porches and multiple exterior coatings. The right response depends on the actual componentānot simply the age or neighborhood.
Document the inspection with photographs and make preparation part of the written estimate. That protects both the homeowner and the finished result.

Questions homeowners ask
Does every pre-1978 home contain lead paint?
No, but age increases the possibility. Testing or an appropriate regulatory determination is needed before covered work proceeds.
Can cracked plaster simply be painted?
Paint will not stabilize a moving or loose substrate. The cause and condition should be evaluated before cosmetic repair.
Should original trim be replaced?
Not automatically. Sound historic trim can often be repaired and refinished; deteriorated or unsafe components may require replacement.
