Priority-based chimney repair for Nicholtown's deferred-maintenance homes — urgent structural repairs, near-term joint repointing, and long-term monitoring plan. Written scope before work begins.
When a chimney has deferred maintenance spanning many years, not every problem needs the same urgency. Triage assigns each failure to a priority tier so repairs address active damage first.
Crown failure allowing water direct entry into the flue. Missing or loose brick sections at the top of the stack. Step flashing pulled completely away from the chimney face. These create ongoing water infiltration and deteriorate the structure faster with each rain cycle.
Mortar joints recessed more than 1/4 inch across large sections of the exterior stack. Corbel mortar friable and crumbling. Individual spalled brick faces exposing the brick core. These are not causing immediate structural failure but will reach urgent status within one to two winters.
Surface erosion at joints less than 1/8 inch. Hairline crown cracks not yet open enough to allow water entry. Efflorescence (mineral deposits) on exterior face that indicate past moisture but no current active infiltration path.
Surface recession 1/8 inch — tuckpointing alone would have resolved at minimal scope
Joints recessed 1/4–3/8 inch — water now entering, crown starting to separate at collar
Moisture-driven freeze-thaw fracturing brick faces — tuckpointing plus brick replacement now needed
Courses shifting, interior damage visible — full triage and prioritized multi-phase repair required
