Why Our Professional Chimney & Vent Installation Delivers Safe Draft, Clean Flames, and Long-Term Protection
You want an outdoor fireplace that lights fast, drafts cleanly, and keeps smoke and sparks away from your guests and roof. Professional chimney and vent installation is the smartest way to avoid downdrafts, leaks, and code issues. When we handle your chimney & vent installation for outdoor fireplaces, you get predictable performance, proper clearances, and materials that stand up to Houston humidity, heat, and wind.
Safety & Risk Elimination
Your family’s safety comes first. We follow NFPA 211 and manufacturer listings for clearances, firestops, and penetrations. For wood-burning units, we add spark arrestor caps (typ. 3/4-in mesh) to reduce ember escape and roof ignition risk. For gas systems, we pressure-test with a manometer and verify shutoff placement by a licensed plumber.
We prevent smoke roll-out and downdrafts with correct flue sizing, the 3-2-10 rule, and wind-resistant or hurricane-rated caps. On covered patios, we map soffit and beam clearances to prevent heat buildup and unsafe recirculation.
Professional Results & Quality
We specify UL 103HT Class A chimney, UL 127 factory-built components, coaxial direct vent pipe, or clay flue tiles as appropriate. We integrate step and counter flashing, crowns with drip edges, and breathable masonry sealers to protect against leaks.
Draft is verified with a smoke pencil/draft gauge. We use laser levels and plumb lines for straight, stable stacks, and chase construction that resists movement and water intrusion - so your fireplace looks great and performs for years.
Time & Stress Savings
Skip the guesswork. Our team handles design, permit pulling, and inspection coordination with the City of Houston. Most projects complete in 1–3 days on-site once permits are issued.
We bring scaffolding, roof anchors, and PPE for safe, efficient work - plus sheet metal brakes and snips for custom chase covers and flashing made to fit your exact conditions.
Cost-Effective Solution
Improper venting leads to soot staining, smoky patios, and costly leak repairs. We prevent rework by sizing the flue to the firebox (1/10–1/12 rules), setting proper termination height, and using corrosion-resistant materials like 316 stainless near coastal air.
Our correct installs help you avoid damaged shingles, warped soffits, or cracked masonry crowns - common outcomes when shortcuts are taken. You get durable performance and fewer maintenance calls.
Peace of Mind & Warranty
We’re fully insured and adhere to Houston Mechanical and Plumbing inspections. You’ll receive documentation of materials, permits, and testing results, plus a clear walkthrough of safe operation and maintenance.
Every project includes a written workmanship warranty and manufacturer-backed component warranties. We also offer post-install maintenance plans and Level 1/2 inspections to keep your system operating safely.

We size flues at roughly 1/10 (square/rectangular) or 1/12 (round) of the firebox opening, apply the 3-2-10 rule, and position terminations away from openings/soffits. For weather protection, we pour crowns with drip edges, integrate step and counter flashing, and waterproof masonry with breathable sealers.

Frequently Asked Questions
Do outdoor fireplaces need a chimney or flue?
Most outdoor fireplaces require a chimney or approved vent to move smoke and combustion byproducts away from people and structures. Wood-burning units typically use a masonry flue or Class A chimney. Many gas units are direct vent or B-vent per their listing. We size and install the correct system for your model, patio cover, and Houston wind conditions so it drafts cleanly and stays code-compliant.
How high should an outdoor fireplace chimney be?
We apply the 3-2-10 rule: the chimney termination should be at least 3 feet above the roof penetration and 2 feet higher than any point within 10 feet. On patios and pergolas, we also evaluate nearby walls, soffits, and wind exposure to prevent downdrafts. Our team uses laser levels and a chimney height calculator to set a height that drafts well in Greater Houston.
Can you put an outdoor fireplace under a covered patio?
Yes, if the unit is listed for use under a cover and clearances are met. We verify manufacturer instructions, map beam/soffit clearances, and place vent terminations away from openings. For gas, many direct vent models work well under covered patios. For wood-burning, we ensure proper flue height, spark arrestors, and heat clearance so Houston inspectors approve it safely.
Do gas outdoor fireplaces need to be vented?
Many outdoor gas fireplaces are direct vent or B-vent per ANSI Z21.50/Z21.88 or ANSI Z21.97 listings. Some decorative appliances are designed for open-air use without traditional chimneys, but still have strict clearance and termination rules. We confirm your model’s requirements, size the vent appropriately, and coordinate a licensed plumber for the gas line and shutoff placement in Houston.
Do I need a permit for an outdoor fireplace in Houston?
For vented fireplaces, yes. As of December 1, 2023, the City of Houston generally requires a mechanical permit, and gas piping requires a gas permit by a registered Master Plumber. We handle iPermits, plan review questions, and inspections. You’ll receive documentation showing compliance so your project passes and closes out correctly.
What size flue do I need for my outdoor fireplace?
We typically size the flue to about 1/10 of the firebox opening for square/rectangular flues or 1/12 for round, then adjust for chimney height, wind exposure, and offsets. Direct vent and B-vent systems follow manufacturer sizing charts. We verify draft with a smoke pencil and select a cap that helps reduce downdrafts common in Houston.
How do wind-resistant chimney caps work on the Gulf Coast?
Wind-resistant and hurricane-rated caps use directional baffles and pressure zones to shield the flue from crosswinds and gusts. They help maintain draft and reduce smoke roll-out during windy Houston evenings. We often specify 316 stainless for corrosion resistance near Galveston Bay and position terminations to minimize turbulence around parapets and soffits.
Can I use my outdoor fireplace during a burn ban?
Burn bans in Harris County often restrict solid-fuel burning. Gas appliances may be allowed if they meet listing and clearance requirements. We can recommend enclosures and fuel options that reduce smoke and help you stay within local rules. Always check current burn ban guidance before use; we’re happy to advise on compliant operation.
What inspections are required after chimney installation?
We recommend a Level 2 inspection for new or modified systems, which includes visual and camera checks. Houston Mechanical and Plumbing inspections verify code compliance, clearances, and gas pressure/leak testing when applicable. After approval, we provide photos, test results, and documentation for your records and warranty.
Who pulls the gas permit in Houston for outdoor fireplace installs?
Gas permits must be pulled by a City of Houston–registered Master Plumber. We coordinate that, ensure proper shutoff and sediment trap placement, and schedule inspections. Our team installs the venting and chimney system, then the plumber pressure-tests the gas line with a manometer to confirm safe, compliant operation.
