Common Chimney Issues in Boston’s Weather
Boston’s freeze thaw cycles, ice dams, and salt air can cause chimney failures leading to leaks, draft issues, and safety hazards.
How to Spot Chimney Damage
- Cracks & Spalling: Chunks of brick or mortar flaking off.
- Leaning Stack: A vertical shift indicating foundation or footing issues.
- Rust Stains: Corrosion of metal flashings or connectors.
Repair vs. Full Restoration: What You Need
Minor tuckpointing and waterproofing can extend life by 5–10 years; full rebuilds may be required for severely deteriorated stacks.
Step 1: Tuckpointing and Repointing
Removing old mortar and repacking with a matched Portland-lime mortar blend restores strength and water resistance.
Step 2: Waterproofing and Cap Installation
A properly installed chimney cap and breathable sealant prevent moisture intrusion while allowing vapor escape.
Step 3: Flue Liner Inspection and Replacement
Inspect your clay, cast-in-place, or stainless-steel liner for cracks. Relining ensures safe exhaust of combustion gases.
Step 4: Masonry Rebuilds and Crown Repair
When the crown is cracked or the brick shell compromised, we’ll rebuild with reinforced materials and a water-deflecting overhang.
Maintenance Tips to Extend Chimney Life
- Annual chimney sweep to remove creosote.
- Post-storm inspections for cracks or loose bricks.
