Chimney Repair & Services in Harrison, NJ

If you've noticed water stains near your chimney, deteriorating mortar joints, or a musty smell coming from your fireplace area, the problem is almost certainly at the roof line. Chimney flashing failure is the #1 cause of chimney-related leaks, and it's a straightforward fix when caught early.

Chimney Services for Harrison Homes

With Harrison's rapidly developing community near the Passaic River with new construction and historic buildings, we see specific roofing patterns unique to this community. Our chimney-related services include:

• Chimney flashing replacement — removing old flashing and installing new step flashing, counter flashing, and cricket/saddle assemblies
• Chimney crown repair — patching or rebuilding the cement cap that protects the top of the chimney stack
• Chimney cap installation — stainless steel or copper caps that prevent rain, snow, and animals from entering
• Chimney leak diagnosis — determining whether water entry is from flashing, crown, cap, or masonry failure
• Cricket/saddle installation — the small peaked structure behind wider chimneys that diverts water around the stack
• Mortar joint waterproofing — sealing porous masonry at the roof line to prevent absorption

The Most Common Chimney Problem

90% of the chimney calls we get in Harrison turn out to be flashing issues. The metal pieces that seal the gap between chimney masonry and roof shingles take a beating — thermal expansion/contraction, ice formation, and sealant degradation all work against them. The good news: reflashing a chimney is a $500-$1,200 repair that stops leaks permanently when done correctly.

When to Address Chimney Issues

Don't wait for interior water damage. Signs that your Harrison chimney needs attention: water stains on the ceiling or walls near the chimney, white efflorescence (salt deposits) on exterior masonry, deteriorating mortar joints above the roof line, missing or damaged chimney cap, and any visible gaps between flashing and masonry.
