Multi-Flue Chimney Cap

A stack with two or three flues — a fireplace and a furnace, or two fireplaces — is usually running separate small caps or none at all, and the crown between them stays wet all winter. A multi-flue cap is a single fabricated stainless or copper lid that spans the whole crown, covering every flue and the masonry underneath in one piece. We measure the crown and the flue heights on site, because these are built to the chimney rather than pulled off a shelf, then anchor the base band to the crown and screen the sides to NFPA 211 mesh sizing. Price moves with the crown's footprint and the metal you choose — stainless as standard, copper on request.

What is it

What is multi-flue chimney cap?

A stack with two or three flues — a fireplace and a furnace, or two fireplaces — is usually running separate small caps or none at all, and the crown between them stays wet all winter. A multi-flue cap is a single fabricated stainless or copper lid that spans the whole crown, covering every flue and the masonry underneath in one piece. We measure the crown and the flue heights on site, because these are built to the chimney rather than pulled off a shelf, then anchor the base band to the crown and screen the sides to NFPA 211 mesh sizing. Price moves with the crown's footprint and the metal you choose — stainless as standard, copper on request.

Every multi-flue chimney cap includes:

  • Crown and flue terminations measured for a made-to-fit cap
  • Single fabricated stainless or copper lid covering every flue
  • Spark-arrestor mesh sized to NFPA 211
  • Base band anchored to the crown, draft clearance verified

Scoped from a graded inspection

At Texas Chimney Experts, a multi-flue chimney cap is never guesswork. We scope every job from a graded, photographed inspection first — the NFPA 211 level the evidence calls for — so the work is matched to what your flue and masonry actually need, with the report to prove it. The documented inspection is the record the multi-flue chimney cap is built on.

FAQ

Common questions about multi-flue chimney cap.

How often should I have my chimney swept?

The standard is condition-driven, not calendar-driven: NFPA 211 ties cleaning to a measured 1/8" of creosote accumulation, and a Level 1 inspection is the way we confirm you've reached it. For a wood-burning fireplace in regular use that typically lands at once per heating season — but we measure the buildup and tell you what the flue actually shows rather than assuming.

Are your technicians certified?

Yes — and verifiably so. Our inspectors hold current CSIA (Chimney Safety Institute of America) certifications you can confirm yourself in the CSIA member directory at csia.org, and our fireplace work is handled by NFI specialists. We name the standard we inspect to so you can check the credential behind the report.

Do you offer emergency service?

Yes. We respond 24/7 (subject to crew availability) to the situations that can't wait for a diagnosis later — an active water leak into the home, an animal trapped in the flue, post-fire hazards, and storm damage. We make the system safe first, then document the cause; same-day in most cases.

Do you provide written quotes before work begins?

Always — and with the evidence attached. Before any work starts you receive a written quote backed by photos of exactly what we found and why it needs attention. Final pricing follows the documented condition of the chimney and anything the inspection turns up, not a number guessed before we've looked.

What's the Inspection Program membership?
