Code-compliant chimney liner installation in 316Ti / 304 stainless steel or HeatShield Cerfractory cast-in-place, sized to the appliance and engineered for the BTU load — installed by CSIA-Certified technicians and warrantied for life on workmanship. In the Houston metro, Prime Chimney Experts is the regional standard for chimney liner installation — and we deliver it the way a Master Mason, a CSIA-Certified Chimney Sweep, and a Texas-licensed plumber would deliver it on their own home.
Why Houston Chimneys Demand a Different Standard
Climate. Houston’s climate is the inverse of DFW’s: extreme humidity, heavy rainfall (50+ inches annually), Gulf-storm wind loading, and only 5-10 freeze-thaw cycles per year. The dominant chimney threats here are sustained water absorption, hurricane-force lateral wind loads, and the corrosion of metal components in salt-laden coastal air (especially within 30 miles of Galveston Bay).
Housing stock. Houston chimneys span River Oaks 1920s brick masterpieces, Memorial and Tanglewood 1960s-1980s ranch-revival chimneys, and The Woodlands / Sugar Land / Bellaire 1990s-present custom builds in stone veneer over CMU. The Houston market also has the largest inventory of pre-fab metal chimney chase systems of any Texas metro — and these chases are the leading source of water-intrusion calls in 77024, 77005, and 77019.
Code and permitting. City of Houston enforces the 2021 IRC. The unincorporated portions of Harris, Fort Bend, and Montgomery counties operate under separate enforcement regimes. Hurricane wind-load requirements (ASCE 7 Risk Category II) apply to all chimney terminations, and chase covers in the coastal zone must be 304 stainless or 16-oz copper — galvanized steel is not serviceable in Houston’s humidity.
Coverage. Service area includes Harris County, Fort Bend County, Montgomery County, Galveston County north of the causeway, and the inner-ring of Brazoria and Liberty Counties. Premium response for River Oaks, Memorial, Tanglewood, West University, Bellaire, The Woodlands, and Sugar Land’s First Colony / Sweetwater / Riverstone communities.
Our Chimney Liner Installation Process
Every chimney liner installation project we perform in Houston follows the same disciplined sequence — the sequence that produces a result you do not have to think about again for decades.
- Pre-installation Level 2 video scan to confirm flue condition and identify offsets, breaches, or tile failure
- Appliance-correct sizing: liner diameter calculated to the appliance manufacturer’s input rating (oversized liners cause condensation and creosote; undersized liners cause downdraft)
- 316Ti stainless liner for wood-burning and high-efficiency gas appliances; 304 stainless for atmospheric gas; AL29-4C for Category IV condensing appliances
- HeatShield Cerfractory cast-in-place liner for chimneys where the original tile must be preserved and the flue geometry has minor offsets (a structural-restoration option, not a relining option)
- Top-mount and bottom-mount installations, with proper insulation wrap (Thermix or pour-in vermiculite) on solid-fuel applications
- New top plate, storm collar, rain cap, and chase-cover integration — all stainless, all sealed with high-temp silicone
- Carbon-monoxide and draft-pressure testing on every gas appliance after liner installation
Materials, Certifications, and Standards
Prime Chimney Experts holds the credentials and standards that matter for premium Houston masonry work:
- CSIA-Certified Chimney Sweep — every technician on every job; we do not subcontract inspections or critical repairs.
- Master Mason on staff — for stone-matching, historic brick repointing, and structural-restoration work that requires a different skill set from production masonry.
- Texas-licensed Plumber on staff for gas-appliance work — required by Texas Occupations Code Chapter 1301 for any gas-line modification, and a credential most chimney contractors do not maintain.
- $2M general liability + $1M umbrella + Texas Workers’ Comp on every technician — certificates of insurance issued directly to your insurer or HOA before work begins.
- Compliance:NFPA 211 §7 (chimney lining requirements), UL 1777 (chimney lining systems), ICC G3 (gas appliance venting), and the IRC in force at your municipality.
Lifetime Workmanship Warranty
Workmanship: lifetime, transferable once. Liner: manufacturer lifetime warranty (Olympia, Forever Flex, or DuraVent — varies by application). Cerfractory: 20-year manufacturer warranty. Our warranty is documented on company letterhead, signed by the Master Mason or CSIA-Certified Chimney Sweep of record, and is transferable once to a subsequent owner — a meaningful resale-value factor on every Houston property we touch.

Frequently Asked Questions — Houston
How does Houston humidity affect my chimney?
Sustained high humidity does two things: it keeps mortar and brick from drying out between rainfalls (accelerating freeze-thaw spalling on the few cold nights per year), and it corrodes any non-stainless metal component on the chimney top. Galvanized chase covers, cap collars, and damper hardware fail within 8-12 years in Houston — we replace these with 304 stainless or 16-oz copper as a standard.
Do you handle hurricane damage and insurance claims?
Yes. After Harvey, Beryl, and the 2024 derecho, we processed hundreds of Houston-metro chimney-damage claims with USAA, State Farm, Allstate, Chubb, and Texas Windstorm. We document storm-attributable damage to insurance-carrier specifications and bill the carrier directly when authorized.
My chimney chase is metal, not masonry — do you service those?
Yes. Pre-fab metal chase systems are extremely common in Houston, and they have specific failure patterns (chase cover rust-through, flashing kick-out, chase-wall water intrusion, factory-built firebox damage). Our technicians are trained on Superior, Heatilator, Majestic, FMI, and Astria factory-built systems.
Frequently Asked Questions — Chimney Liner Installation
Why does my Houston chimney need a new liner?
Three common reasons in Houston: (1) the original clay tile liner has cracked or shifted from age, freeze-thaw, or a chimney fire — and a damaged liner is a code violation and a carbon-monoxide hazard; (2) you are installing a new appliance (high-efficiency gas furnace, wood stove insert, or pellet stove) and the existing flue is oversized or the wrong material for the new appliance; (3) the existing flue is unlined entirely — which is common in pre-1940 Houston homes and is no longer code-compliant under NFPA 211.
How do I know what diameter and material my liner should be?
We calculate the liner diameter from the appliance manufacturer’s input rating, the flue height, and the offset geometry. The material follows the fuel: 316Ti stainless for wood-burning and high-efficiency gas; 304 stainless for atmospheric gas; AL29-4C for Category IV condensing appliances. Oversized liners cause condensation and creosote accumulation; undersized liners cause downdraft and CO intrusion. This is a calculation, not a guess — we show our work in the proposal.
What is the difference between a stainless liner and a Cerfractory cast-in-place liner?
Stainless is a flexible or rigid metal pipe inserted inside the existing flue, insulated with a wrap, and capped at the top and bottom. Cerfractory is a poured ceramic-aggregate material that bonds to the existing flue walls and effectively rebuilds the flue in place. Stainless is faster and lighter (3-5 days, 1-2 technicians). Cerfractory is structural — it actually restores the strength of a damaged flue and preserves the original chimney’s exterior appearance — but it takes 5-7 days and a larger crew. Both carry industry-leading warranties.
Will a new liner improve my chimney’s draft?
Almost always, yes. A properly-sized, insulated, smooth-walled stainless liner reduces friction loss, keeps flue gases at a higher temperature on the way out, and dramatically improves draft on cold mornings — especially on tall chimneys serving high-efficiency appliances. Many homeowners report that a previously balky fireplace or appliance becomes effortlessly easy to light after a correct liner installation.

About Houston Chimney Services
Houston is home to 2.3M residents within the 7.1M metro area, spanning 110 ZIP codes. The local building stock averages 35 years old — putting most Houston chimneys in critical maintenance years.
Local climate factors: Houston experiences a humid subtropical climate with 3-8/year of freezing weather and 3-5/year of major hail events annually. Freeze-thaw cycles damage chimney crowns, and hail damages caps — both are top causes of leaks in Houston homes.
Insight specific to Houston: Houston's high humidity (avg 75%) accelerates creosote off-gassing — homeowners often report tarry smell when AC runs.
Local Service Recommendations
- Annual inspection — recommended for Houston homes due to humid subtropical conditions
- Crown inspection — critical given 3-8/year of freeze cycles
- Cap upgrade — stainless steel caps survive Houston's hail events
