Chimney Cap
Flue termination measured, then a stainless or copper cap fitted to NFPA 211.
Learn moreVenting is governed entirely by its UL listing — the clearances, the firestopping, the termination are all dictated by that document, not by what fits. We install B-vent, direct-vent, or Class A to the listing: penetrations firestopped at each floor, termination cap sized to code, clearances to combustibles held the full run. Those clearances are measured and the path documented before close-up, so the venting is verified to the listing rather than assumed compliant.

A vent is the one chimney system whose failure mode is carbon-monoxide exposure, so Texas Chimney Experts treats the install as a code-and-measurement job from the first reading. The appliance's combustion gases have exactly one safe path out; the wrong vent category, size, routing, or clearance sends them back into the living space instead. We start from the manufacturer's listing for your specific appliance — the controlling document, not a generic gap — and size the system to its heat output and the NFPA 54 tables. There is no premium shortcut on a vent, because the metric it's judged by is whether the gases provably leave.
The correct vent is a specification, never a default. A B-vent (natural-draft) appliance, a sealed-combustion direct-vent fireplace, and a Class-A solid-fuel chimney each carry different requirements for material, clearance to combustibles, and termination — and the manufacturer's listing for your specific appliance is the controlling document. The system is matched to the appliance and the install, sized to the heat output and routed so the gases draft reliably. Choosing the wrong category, or mixing components not listed together, is exactly the mistake that produces spillage down the line.
Routing is where the workmanship is measured. The vent is run with the correct pitch and support, the required clearances to framing and combustibles held at every point, offsets negotiated without choking the draft, and the termination set at an approved location with the proper cap. Every connection is sealed to spec so the system is gas-tight along its full length, because a vent is only as safe as its weakest joint.
A completed install is proven, not assumed: a draft check and a CO-safe operational test confirm the appliance vents the way it's designed to, and the work is documented for your inspection and records. That verification is the line between a vent that was installed and one that's provably safe — the same standard our technicians hold on every gas install across our national network.
At Texas Chimney Experts, a chimney vent installation 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 chimney vent installation is built on.
Chimney inspectionA chimney vent installation isn't a matter of opinion — it's held to published national standards. Texas Chimney builds every job to the named codes below and documents it, so the work is provably right for an inspector, an insurer, or a future buyer. These are the universal standards; your city's permit and inspection requirements are confirmed with the local authority before we pull the job.
Sizing and routing for gas-appliance vents follow the NFPA 54 (National Fuel Gas Code) Category I venting tables; that is what makes combustion products draft out reliably rather than spilling back into the home.
On a factory-built Class A solid-fuel chimney, the pipe we install is UL-103HT listed, tested for high-temperature and chimney-fire conditions, and it is installed to that listing.
Whether the system is B-vent, direct-vent, or Class A, the clearance to combustibles comes straight from the appliance and pipe listing. The manufacturer's listing controls the number; a generic gap does not.
Termination gets the same scrutiny as the run: an approved location, the correct cap, and the required clearances from windows, soffits, and grade, so the flue gases discharge safely clear of the building.

Inspection-ready documentation
Family-owned, CSIA-certified, NFPA 211–compliant. We're the team you call when you want it done right the first time — no rotating subcontractors, no upsell pressure, no surprises. Same techs, same trucks, same standard.

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.
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.
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.
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.
Flue Watch is our annual maintenance plan at $19.99/month ($240/year): a documented Level 1 inspection and sweep every year ($248 value), priority scheduling, 10% off all repairs, and emergency-response priority. It's the way to keep a year-over-year record of your system's condition. Cancel anytime, no contract.
