Chimney Flashing Repair in
Mercer County, NJ

Aluminum chimney flashing serves the majority of Mercer County's residential market — Hamilton Township's large postwar colonial and split-level inventory, Ewing Township's standard residential stock, and Trenton's urban housing where cost-effective performance at a reasonable cost is the primary objective. We specify pre-painted aluminum with factory-applied coatings that resist Mercer County's inland moisture and Delaware Valley humidity conditions — never bare or field-painted aluminum that humidity conditions degrade within 10 years.

Our Hamilton Township aluminum installations consistently replace roofing cement repairs from previous service visits — a pattern we see across the county's postwar housing stock where original steel step flashing has corroded and been covered with cement rather than properly replaced. We remove all existing cement and failed flashing, assess the underlying deck and sheathing for moisture damage, and install new step-and-counter flashing in properly overlapping configuration with mortar-joint counter flashing embedded at the correct height. For Trenton's urban properties, we apply the same complete replacement standard — no cement over cement, no partial repairs.
