Trusted Fireplace Repair for Houston Homeowners
Fireplace repair in Houston usually means one of three things: a gas unit that won’t light or stay lit, a wood-burning firebox with cracked masonry, or a flue system that’s no longer venting the way it should. Most repairs we complete run between $180 and $650 for common issues like thermocouple replacement, gas valve service, or firebox parging. A full reline with a stainless DuraFlex system lands higher, typically $2,200 to $4,800 depending on flue height and access. Ashby Chimney Houston has handled Houston Fireplace Repair across the area since 2002, and when you call (903) 961-6496, a live person answers, day or night.
Nathan Corliss runs this shop on one principle: show the homeowner what’s wrong before asking for a dollar. That means camera inspection, written findings, and a written price before any work starts. No exceptions.
Gas Fireplace Repair
Gas Fireplace Repair covers the mechanical and venting systems that keep a gas-burning fireplace lighting reliably and exhausting correctly. You need it when the pilot won’t stay lit, the main burner fires weak or uneven, you smell gas, or the glass is sooting up in patterns that indicate incomplete combustion. In Houston, the most common call we get is a pilot assembly that’s been fouled by dust and humidity, a $180 to $340 fix depending on the make. Nathan Corliss and his technicians test gas pressure, clean the burner pan and jets, replace thermopiles and thermocouples when readings confirm they’ve failed, and verify the vent draw with a draft gauge before calling the job done.
Diagnosis First, Parts Second
We don’t hand over a parts list after two minutes at the hearth. Every gas fireplace repair starts with a diagnostic sequence: gas pressure at the valve inlet and manifold, millivolt output from the thermopile, and a combustion check at the glass. That sequence tells us whether the problem is fuel delivery, ignition, or venting, and it keeps us from replacing a $30 part when the real issue is a blocked exhaust run.
What We Typically See in Houston Homes
In this climate, humidity is a bigger enemy than cold. We regularly open gas units in Bellaire and West University where spider webs inside the burner orifices have caused delayed ignition. In older homes around the Heights and nearby Highlands Fireplace Repair calls, it’s often a 15-year-old standing pilot assembly that finally gave out. These are known failure points, and we fix them with OEM or equivalent parts, not whatever the supply house had on clearance.

Gas Fireplace Service
Gas Fireplace Service is a preventive cleaning and tune-up rather than a repair. It’s what a gas fireplace needs once a year, ideally before the short Houston heating season starts. The service includes removing the glass, cleaning the burner pan and logs, checking gas connections for leaks with an electronic sniffer, testing the safety shutoff, and verifying that the venting is drafting properly. Most gas fireplace service in Houston runs between $120 and $170 for a standard direct-vent unit. It’s the cheapest way to catch a failing thermopile in November instead of discovering it on the first 40-degree night in January.
Beyond the Basic Tune-Up
A proper gas fireplace service goes past vacuuming the fake embers. We pull the glass gasket to check for seal wear, inspect the thermopile and thermocouple outputs under load, and confirm the pilot shield has no rust-through. If any of those fail the spec, we’ll show you the readings and give you a written price to fix it before it strands you on a cold evening.
Why Annual Service Holds Up
Dust, pet hair, and the fine grit from Houston humidity settle into gas controls all year. A unit that runs fine in February can have a lazy pilot flame by October. Annual service resets all of that and gives you a written record, which matters if you ever sell the house. Buyers in Houston do ask about fireplace maintenance history, and a clean service log answers the question.
Fireplace Insert Installation
Fireplace Insert Installation is the process of setting a self-contained gas insert into an existing wood-burning firebox and connecting it to a properly sized vent liner. You need it when you’re done fighting an open hearth that sends more heat up the chimney than into the room, or when the masonry is too far gone to use safely as-is. A typical gas insert installation in Houston runs from $3,200 to $6,800, including the liner, gas connection, and finish work on the surround. Ashby Chimney Houston installs inserts from major brands with direct-vent technology, which draws outside air for combustion and exhausts through a sealed pipe, a much better fit for Houston’s tight homes than a natural draft setup.
Sizing the Insert to the Firebox
Not every beautiful old firebox fits a modern insert. We take inside width, height, depth at top and bottom, and rear width before recommending a unit. A firebox in a 1980s Memorial-area home might be 42 inches wide with a clay-tile flue, while a newer build in Katy or Fireplace Repair in Spring territory might have a prefabricated box that limits us to specific direct-vent models. The measurements drive the recommendation, and we’ll tell you honestly if an insert doesn’t make sense for your fireplace.
Liner and Venting Requirements
The insert is only as good as the liner behind it. We run a properly sized stainless or flexible liner inside the existing chimney to match the insert manufacturer’s specs, and we verify termination height and clearances at the cap. Skipping the liner or running an undersized one is the most common mistake we correct from previous half-done installations.
Gas Fireplace Installation
Gas Fireplace Installation means adding a gas fireplace where one doesn’t exist, whether that’s a full direct-vent unit framed into a wall or a log set placed into a masonry fireplace that previously burned wood. You need it when you want the look and heat of a fire without the work of wood. Installed costs around Houston typically run $3,800 to $9,500 depending on whether gas lines need to be added or extended, the venting route required, and the unit’s Btu rating. Ashby Chimney Houston handles the full job: gas line work to code, sealed direct-vent piping, firestop and clearance requirements, and a final operational test with gas and carbon monoxide checks.
New Construction vs. Retrofit
Putting a fireplace into a new build is cleaner but still requires planning for wall depth, vent routing, and finish clearances. Retrofitting into an existing room usually means opening a wall to run the vent and gas line, which adds labor and some drywall repair. We’ll give you a written scope and price for your specific layout before any tools come out.
Code and Clearance Details
Houston’s permitting offices enforce clearance-to-combustibles requirements strictly, and for good reason. We’ll verify the unit sits with proper side, top, and hearth clearances per the manufacturer’s listing and city code. If a builder-grade wall was never meant to hold a 300-pound gas unit, we address the structure before the unit goes in.
Gas Fireplace Maintenance
Gas Fireplace Maintenance is the recurring upkeep that keeps a gas fireplace burning safely and efficiently year after year. It overlaps with service but focuses more on inspection intervals and the manufacturer’s maintenance schedule: cleaning the glass interior, inspecting gaskets and seals, checking the log alignment, testing the ignition and safety systems, and confirming the vent termination is clear of debris. A standard maintenance visit in Houston runs $120 to $180. If you use your fireplace even a dozen times a year, annual maintenance is the right cadence. If you burn it nightly through the cold months, we suggest a mid-season check too.
Troubleshooting a Noisy or Smelly Unit
Rumbling from the burner pan often means an air-to-gas ratio that’s drifted out of spec. That’s a quick adjustment. A sooty smell when the unit lights is usually dust burning off the logs or glass, a normal thing after a long idle stretch. But a persistent odor during operation is a signal to stop using the unit and get it checked, and that’s exactly what our maintenance call exists to determine.
Checking the Vent and Seal Integrity
Direct-vent fireplaces depend on a sealed combustion path. We check the vent pipe connections at every accessible point, confirm the termination cap isn’t blocked by leaves after Houston’s fall winds, and test the door gasket with a draft gauge. A pinhole leak in a vent joint inside a wall can put trace amounts of carbon monoxide into a home over a full season, which is exactly why maintenance is not a luxury.
Wood Stove Installation
Wood Stove Installation is the process of setting a freestanding wood stove on a proper hearth pad and connecting it to a new stainless chimney system or an existing masonry flue that’s been inspected and lined. You need it when you want real, off-the-grid heat for the occasional Houston cold snap or power outage after a storm. Wood stove installation in this area typically runs $2,500 to $6,200, with the spread driven by whether you need a full chimney run from scratch or can tie into an existing fireplace flue. Ashby Chimney Houston installs stoves to the manufacturer’s clearance specs and Houston mechanical code, including hearth R-value requirements and wall shielding.
Hearth Pad and Floor Protection
Wood stoves radiate serious heat downward and to the sides. The hearth pad isn’t decoration. It has to meet the specific R-value for the stove you choose, and that changes by model and by floor construction. We’ll review your flooring type against the stove supplier’s chart and tell you if a stock pad works or if you need a custom built-up hearth.
Chimney Pipe vs. Liner Tie-In
The cleanest wood stove installation is a straight run of Class A insulated chimney pipe through the roof, which costs more in materials but avoids all masonry questions. Tying into an existing brick chimney requires a liner and a block-off plate at the top of the firebox, and sometimes a full reline if the clay tiles are cracked. We’ll camera the existing flue first and show you the images before recommending one path or the other.
Brands We Service
We work on and install units from nearly every major gas fireplace brand, but a few stand out from our service calls in Houston. HeatShield, for example, is a resurfacing system we use regularly to save a damaged flue from full replacement. It’s a ceramic coating applied inside the existing tile liner, and it’s solved the problem for dozens of homeowners in older neighborhoods like Garden Oaks and Meyerland where demolition would have been the only alternative.
DuraFlex liners are our default when a chimney needs a new stainless flue, for wood stoves, inserts, and furnaces. They’re flexible enough for offset flues and rate clean across the board. Gelco products come out when we rebuild caps, crowns, and wash. Whether you have a unit from one of those brands or any other make, we can help. Call Nathan Corliss at (903) 961-6496 and we’ll tell you what you’re working with and what it’ll take to fix it.

- Pilot won’t stay lit after multiple attempts. A pilot that lights but won’t hold typically points to a failing thermopile or thermocouple, not a “tricky valve.” Forcing it repeatedly can overload the gas control. We read millivolt output on the spot and replace only what’s failed.
- Sooting or black streaks on the glass or logs. Soot means incomplete combustion, which can be an air shutter out of adjustment, a blocked burner port, or a venting restriction. Left alone, it builds on the inside surfaces and can degrade the unit’s performance and safety.
- You can smell gas or a faint rotten-egg odor near the fireplace. That’s the mercaptan odorant added to natural gas. If you detect it, shut the gas valve off at the unit, leave the area, and call us from outside the house. We’ll trace the leak with a sniffer and repair it before turning anything back on.
- Spalling brick or crumbling mortar in the firebox. Water and heat have broken the masonry down. Spalled firebox panels can expose combustibles behind the firebrick to direct heat. We parge and replace with proper refractory material, not standard mortar, which will crack again under heat cycles.
- White stains on the exterior chimney or smoke smells inside on humid days. That’s moisture working into the flue system. In Houston’s climate, it’s an everyday threat. The fix is usually a cap repair or crown reseal before the liner itself takes on water, and we’ll show you the camera footage that proves it.
Our Process, Step by Step
- 1
Call and schedule a real window. When you call (903) 961-6496, you speak to a person, not an automated queue. We give you a real arrival window and honor it. If traffic on I-45 or 610 gets the better of us, you’ll hear from us before the window closes, not after.
- 2
On-site diagnosis with camera verification. Nathan Corliss or one of our technicians arrives in uniform, drops floor protection around the hearth, and starts the diagnostic. For any problem involving the flue or venting, we run a camera through the system and record the images. You’ll see what we see, real-time.
- 3
Written price before any work starts. No estimate-with-a-wink, no “we’ll see once we get into it.” We hand you a written line-item price for the repair, with no hidden charges underneath. If the work lies outside the guarantee-covered scope, we’ll note it in writing before waiting to hear your decision.
- 4
Repair work with traceable parts. We use materials from chimney-trade suppliers we’d use on our own houses: DuraFlex for liners, HeatShield for flue restoration, Gelco and Olympia Chimney for caps and crowns. No mystery-brand parts. If the manufacturer sells an OEM component, that’s what goes in.
- 5
Final walkthrough and written guarantee. We show you the completed repair, explain what was done and why, verify operation in front of you, and clean the work area. Then we hand you a written guarantee covering the repair under the Kingswell Guarantee. That’s the whole story at Ashby Chimney Houston.
How Much Does Fireplace Repair Cost in Houston?
A typical gas fireplace repair in Houston runs $180 to $340 for a pilot assembly or thermopile replacement, while a full gas valve replacement lands between $320 and $550 depending on the model. Firebox parging or refractory panel replacement is generally $350 to $750. Liner-related work is the big spend: a stainless DuraFlex reline runs about $2,200 to $4,800, and adding HeatShield resurfacing to restore, instead of replace, a clay tile liner typically comes in under half of that. Installations sit higher: gas inserts at $3,200 to $6,800, gas fireplaces at $3,800 to $9,500, and wood stoves at $2,500 to $6,200.
What drives the price? Flue height, access to the termination point, whether gas plumbing needs to be extended, and the condition of the surrounding masonry. A two-story home in Katy or Richmond with a steep roof pitch costs more to access than a single-story rancher in Pasadena, where our Fireplace Repair in Pasadena team works regularly. You avoid overpaying by working with a shop that shows you camera evidence and gives a written price before work begins. Our estimates are free, itemized, and good for 30 days. Call (903) 961-6496 to book one.
