When to Strip Paint vs. Just Repaint in Boston

When Repainting Is Sufficient

If existing paint is in reasonably good condition — adhering well, minimal cracking or peeling, no more than moderate chalking — scraping the loose areas, sanding transitions smooth, and repainting over the existing coating is the correct and cost-effective approach. This is the right call for the majority of exterior repaint projects on Boston homes. The key is that 'reasonably good condition' means the paint is actually bonding to the substrate, not just sitting on the surface. Paint Quality Institute problem guide →

When Stripping Is Necessary

Stripping becomes necessary in three situations. First: when more than 50% of the painted surface is actively peeling or failing — repainting over this level of failure produces a finish that will fail again quickly because there's no stable base. Second: when excessive paint buildup has obliterated architectural detail on trim work — common on older Boston Victorians with ornate profiles that have been repainted every few years for decades. Third: when switching from paint to stain on wood surfaces — stain can't penetrate through a paint film.

Lead Paint Considerations in Boston

Pre-1978 Boston homes almost certainly have lead paint under current coatings. Stripping lead paint generates significant dust and debris that requires specific containment, protective equipment, and disposal procedures under the EPA's RRP Rule. Any contractor stripping paint on a pre-1978 Boston home must be EPA RRP certified and follow all required practices. This adds cost to stripping projects but is legally required and medically important — lead dust exposure is a serious health risk, particularly for children. EPA RRP certification requirements →

Stripping Methods and Their Applications

Chemical strippers are appropriate for detailed trim work, carved surfaces, and situations where heat would damage the substrate. Heat guns are faster on large flat areas but require care near glass and are not appropriate for lead paint situations (heating lead paint generates toxic fumes). Mechanical sanding or grinding is appropriate for masonry surfaces and heavily built-up coatings on flat areas. The method we use depends on substrate type, lead paint status, and the level of detail in the surface being stripped.

After Stripping: The Foundation for a Lasting Finish

The value of stripping is that it provides a clean, stable starting point for the new coating system. After stripping, all bare wood gets primed with oil-based or shellac primer to seal the grain and provide a consistent base. Any wood rot discovered during stripping gets repaired before coating. The result is a paint job that starts on the best possible foundation — which is why stripped and repainted exteriors last longer than repaint-over-repaint jobs on homes with failing coatings.
