Frequently asked questions
How much does chimney repair cost?
$200-$500 sweep. $1.2-3.5k cap+crown+waterproof. $1.5-4.5k tuckpointing. $5-15k above-roofline rebuild.
Do I need to reline?
Yes if: switching fuel, cracked liner, post-fire, or breaches found at inspection. Stainless flex is the modern standard.
How often to sweep?
Wood: annually before heating season. Gas: every 1-3 yr. Always pair with level-1 inspection.
Cap vs no cap?
Always cap a chimney. $300-$1k all-in keeps animals out, prevents downdrafts, blocks rain entry.
Can I DIY?
No, except for a basic cleaning swept by a CSIA-certified sweep. All structural / liner / flashing work is pro work for code and safety.
