Relining is not a maintenance item — it is a defined-trigger repair. NFPA 211 (the National Fire Protection Association’s standard for chimneys, fireplaces, vents, and solid-fuel appliances) lists four scenarios that require a relined flue. We see all four regularly across DFW:

1. Original clay tile is cracked, shifted, or spalled

Standard 1980s-2000s production homes in North Texas were built with stacked clay tile flue liners. Clay tile is brittle, and three forces commonly destroy it: a chimney fire (creosote ignition spikes interior temperature past 2,000°F and shatters the tile in a single event), foundation settlement (especially on Blackland Prairie expansive clay, which moves the entire stack and shears tile joints), and simple age (mortar between tiles fails at 25-40 years and tiles drop). Any visible crack, gap, or missing tile during a Level 2 video scan is a code-defined reline trigger. A cracked flue allows combustion gas and heat to escape into framing — that is how house fires start.

2. Wood-to-gas conversion

When a homeowner converts a wood-burning fireplace to a gas insert or gas log set, the original flue is almost always oversized for the new appliance. Gas appliances produce cooler exhaust and acidic condensate; they need a smaller cross-section flue to maintain draft, and they need an acid-resistant liner material (304 stainless or 316Ti at minimum) so the condensate doesn’t eat the venting from the inside out. We size every gas conversion liner to the manufacturer’s specified BTU input — not “close enough.”

3. Insert installation (wood, pellet, or gas)

Every modern fireplace insert ships with a manufacturer install spec that requires a continuous, insulated stainless steel liner from the insert collar to the chimney top. This is non-negotiable under both NFPA 211 and the manufacturer’s UL listing. If the insert was installed without a dedicated liner, the warranty on the insert is void and the system is non-compliant.

4. Smoke and draft problems from improper sizing

If a fireplace smokes back into the room, draws poorly, or refuses to start, the underlying cause is often a flue that is the wrong size — usually too large — or has internal obstructions that disrupt airflow. A correctly sized stainless reline solves chronic draft problems that no amount of sweeping will fix.

Stainless Steel — 304, 316Ti, and 316L

Stainless is the workhorse of modern relining and what we install in roughly 80% of jobs. We carry three grades. 304 stainless is rated for wood and oil — strong, economical, the standard for solid-fuel relines. 316Ti (titanium-stabilized) is rated for wood, gas, oil, and pellet — the all-fuel option, ideal when an appliance might change in the future. 316L is our specification for high-condensate gas appliances and wherever acidic exhaust is the dominant concern. All three come in flexible coil for offset chimneys and rigid sections for straight runs. Every stainless liner we install carries our lifetime warranty on both material and workmanship — for as long as you own the home.

Cast-in-Place Refractory

Cast-in-place is a poured refractory cement liner installed by lowering an inflatable bladder down the flue, centering it, and pumping a high-temperature refractory mix around it. When the bladder is removed, you have a smooth, seamless, code-compliant flue that has also structurally reinforced the surrounding masonry. We specify cast-in-place when the brick stack itself is compromised — old common-brick chimneys with deteriorating mortar joints, undersized original flues that need to be slightly enlarged, or stacks where the homeowner wants the longest-life solution available. Cast-in-place liners carry a 50-year material warranty from the manufacturer and our lifetime warranty on the install workmanship.

Aluminum (Gas-Only, Limited Application)

Aluminum is permitted only for venting Category I draft-hood-equipped gas appliances (typically older atmospheric furnaces and water heaters). It is never approved for wood, never for high-efficiency gas, never for fireplace inserts. We will install aluminum when it is the right and code-legal choice — but it does not carry our lifetime warranty (the material itself is not rated for it), and we will tell you that upfront.

Liner Comparison

Every reline follows the same eight-step protocol. We do not skip steps and we do not let an apprentice run a job alone.

1. Camera scan and Level 2 inspection">Level 2 inspection. Before we quote, a CSIA-certified tech runs a video scope down the flue from top to firebox, documenting tile condition, offsets, obstructions, and termination geometry. The footage goes into your written report.
2. Measurement and sizing. We measure flue cross-section, total height, and any offsets, then size the liner to the appliance per NFPA 211 Annex G and the manufacturer’s BTU specification.
3. Flue prep. The existing flue is fully swept, any deobstruction is performed (collapsed tile fragments, animal nests, debris), and damaged tiles are broken out where the new liner needs clear passage.
4. Liner pull-through. For stainless, we pull a continuous flexible or rigid liner from the top down to the appliance connection. For cast-in-place, we lower and center the bladder, then pump refractory.
5. Insulation wrap. Every solid-fuel stainless liner gets a code-required insulation wrap or pour-down vermiculite jacket. Insulation maintains flue temperature, improves draft, and meets the UL listing condition for zero-clearance installs.
6. Top and bottom termination. The top is sealed with a stainless top plate and storm collar; the bottom is connected to the appliance or smoke chamber with a code-rated tee or appliance connector.
7. Smoke test and draft verification. We light a controlled smoke source and verify draw at the termination — every time, before we close the job.
8. Certification and warranty registration. You receive a written certificate, before/after photos, and the lifetime warranty document recorded under your address.

North Texas punishes masonry chimneys harder than the climate suggests. We track four regional drivers that put DFW homeowners on the reline schedule earlier than the national average:

Freeze-thaw cycling. Despite the mild winter reputation, DFW averages 30-40 freeze-thaw events per year. Each cycle drives water deeper into clay tile microcracks, then expands it. By year 25, most untreated tiles are visibly fissured.

Foundation settlement on Blackland Prairie clay. The expansive clay soil under most of Dallas, Collin, and southern Denton counties moves vertically 4-6 inches across a wet-dry season. That movement transmits up the chimney stack and shears tile joints, even when the house foundation itself looks fine.

Hail-driven water intrusion. DFW is in the heart of Hail Alley. A single severe-hail event can crack a chimney crown, tear flashing, and force water down through the tile column for weeks before the homeowner notices a stain on the ceiling. Once water is inside the flue, mortar joints between tiles dissolve.

The 1990s gas conversion wave. Tens of thousands of DFW homes converted from wood to gas log sets in the 1990s and 2000s without a properly sized reline. Those original oversized flues are now eating themselves from the inside out — acidic gas condensate is corroding the clay tile and mortar, and we relines those systems weekly.

We quote every reline in writing after a camera inspection — never sight-unseen. That said, here are the honest 2026 ranges for DFW:

• Standard stainless reline (single-story, straight run, wood or gas): $2,500- $- + installed
• Two-story stainless reline with offset: $4,500- $- + installed
• Insert installation with insulated liner kit: $3,800- $- + installed (excluding insert)
• Cast-in-place full reline: $5,500- $- + installed
• Removal and disposal of old liner or collapsed tiles: $400- $- + add

The four variables that drive the spread are chimney height, roof accessibility (steep slopes and three-story access add labor), liner material grade, and whether the old liner has to come out before the new one goes in. For chimney-fire damage and some hail-related claims, we coordinate directly with State Farm, USAA, Allstate, Farmers, and Liberty Mutual on the documentation side — we have written more covered-claim reline reports than we can count.

Colleyville — Post-Fire Stainless Reline

“We had a flue fire in February — the inspector flagged the chimney as unsafe and our insurance opened a claim the same week. Prime Chimney Experts came out the next morning, ran a camera down the flue, and showed me the cracked tiles on the laptop right there at the kitchen table. They wrote the scope, talked directly to our State Farm adjuster, and three weeks later they had a 316Ti stainless liner installed with insulation, smoke-tested, and registered under their lifetime warranty. Marcus walked me through every step. The fire used to scare me — now I trust the chimney more than I did before it happened.”

— J. Patterson, Colleyville

Westover Hills — Cast-in-Place Full Reline

“Our home is from 1962 and the original chimney had failed mortar joints and an undersized flue that smoked back every time we lit a fire. We talked to three companies — two wanted to sell us a stainless liner and call it done. PCE was the only one who actually scoped the masonry and said, ‘You don’t just need a liner, you need the structural reinforcement of a cast-in-place pour.’ They were right. The pour took one day, and 24 hours later we had a fireplace that drew like a brand new build. Two seasons in, zero smoke, zero issues. The lifetime warranty paperwork is in my file cabinet.”

— D. Reinhardt, Westover Hills

Southlake — Wood-to-Gas Conversion Liner

“We bought the house with a wood-burning fireplace and wanted to convert to gas logs for the cleanliness. Our HVAC guy quoted the install but didn’t want to touch the chimney — said we needed a chimney specialist. PCE came out, measured the flue, sized a 316Ti stainless liner to the new gas log set’s BTU rating, and installed it the same week. They explained that a gas conversion without a properly sized liner would have eaten the clay tile inside of five years. Final price came in exactly on the written quote. Lifetime warranty registered to the address. Professional from first call to final test.”
