NFPA 211 is a guide, not a grade

NFPA 211 is the national standard for chimneys, fireplaces and vents. It names four events that call for a Level 2: a change of owner, a chimney fire, an earthquake and a switch of fuel.

It is not a government test and there is no official pass or fail. If someone says a chimney failed, they mean the report lists conditions below the NFPA 211 mark or the local building code, which need repair before the fireplace is used safely.

When a house is changing hands, the buyer may request work, a price credit or another look. Whether that happens is for the buyer, the seller and the agents to decide. We stay out of the contract.

The usual fixes run from the top of the stack down: cap, crown, chase cover, cricket and flashing, mortar and masonry, liner, smoke chamber, damper, firebox. Add a leak repair when water is involved, or a gas insert when an owner changes fuel.

Priced up front: gas insert $2,800 to $5,650; leak repair $565 to $3,400; cap $170 to $680; cricket $450 to $1,020; cricket with a full flashing replacement $680 to $1,700.

The others wait until after the inspection, because the scan decides the scope. Masonry and crown work is set for dry weather, so the quote comes with a note on timing. Ask us to list what can wait for dry weather and what should not.
