Trusted Fireplace Repair for Miami Homeowners
Fireplace Repair in Miami usually means one of three things: a gas unit that won’t light or is running with a weak, yellow flame, a masonry firebox cracked by salt air and humidity, or an old insert that needs replacing. We fix all three, and we’ll tell you the price before we touch anything. Ashby Chimney Miami has done fireplace repair across Miami-Dade since 2002, and our techs wear uniforms, arrive in the window we gave you, and carry cameras so you can see the problem yourself. If your fireplace isn’t working right, call (850) 787-8597 and talk to a live person, day or night.
Nathan Corliss runs our Miami shop the same way he has since the start: written price first, repair second, written guarantee always. No one should have to guess what a flue repair will cost, and no one should pay twice for the same fix.
Gas Fireplace Repair
Gas fireplace repair covers the mechanical and venting components that keep a natural gas or propane unit burning cleanly: thermocouples, thermopiles, gas valves, pilot assemblies, burners, and the flue liner that carries exhaust out of your home. Most gas fireplace repair calls in Miami fall between $195 and $550, depending on the part that failed and how deep into the unit the problem goes. A cracked liner or failed gas valve will run higher, and we’ll show you the camera footage before we write anything down. Ashby Chimney Miami arrives with DuraFlex and Copperfield components on the van, so the common fixes don’t wait for a parts order. Nathan Corliss does not believe in charging you for a second trip when the first one should have been enough.
Pilot and Ignition Diagnostics
A pilot light that won’t stay lit is usually a failed thermocouple or a blocked pilot tube, not a reason to replace the whole fireplace. We test the millivolt output before we sell you anything. That fifteen-minute check saves Miami homeowners a lot of money.
Burner and Valve Replacement
Yellow lazy flames or a burner that won’t ignite at all signals a gas delivery problem, often the valve or a clogged burner port. We replace only the failed component, with a written price attached. If the repair fails inside the guarantee period, the second visit is free.
Styles & brands we work with





Gas Fireplace Service
Gas fireplace service is the routine cleaning and tune-up work these units need every year or two, and most Miami homes should schedule it before the cool-season months when fireplaces actually get used. We charge between $145 and $265 for a standard gas fireplace service, which includes cleaning the glass, checking the pilot and burner, testing the thermostat and switch, and checking the venting. Think of it like a furnace tune-up for your living room. Ashby Chimney Miami has done this work since 2002, and we use Gelco cleaning compounds that won’t etch firebox glass, rather than whatever’s on sale at the hardware store.
Full Teardown and Cleaning
The burner, logs, and pilot assembly get pulled, cleaned, and inspected before anything goes back in. Gas fireplaces in Miami deal with humid air year-round, and that means oxidation builds up differently than it does up north. We account for that.
Safety Inspection Included
Every service includes checking the flue, the gaskets, and the gas connections for leaks or corrosion. If we find a problem that needs real repair, you’ll get camera photos you can actually see, plus a written price. Nothing gets sold on the spot as a guess.
Fireplace Insert Installation
Fireplace insert installation is how Miami homeowners turn an old, drafty, or unused open fireplace into a sealed, efficient heat source. A full fireplace insert installation in Miami typically runs $3,200 to $6,800 including the unit, liner, and labor. The big variable is whether you’re putting an insert into a sound masonry chimney or one that needs a new liner first. Ashby Chimney Miami has been installing inserts since 2002, and we pull a permit and handle the liner ourselves. Nathan Corliss won’t tell you an old flue is fine just because the insert covers it up. If it needs relining, the camera will show you why.
Wood-Burning Inserts
We install wood-burning inserts from brands that hold up to real use, pairing them with properly sized DuraFlex liners. The liner is the part that matters most: it’s the steel tube that carries smoke and combustion gases from the insert out through the chimney. We don’t skip it, and we don’t leave an old clay flue behind a new firebox.
Gas Inserts and Conversions
For homeowners who’d rather flip a switch than manage firewood, we install direct-vent gas inserts in existing masonry openings. The venting in a direct-vent system is specific, and Miami’s building code has clear requirements for clearances and termination. We handle both, and every job gets a written price before the first tool comes off the van.
Gas Fireplace Installation
Gas fireplace installation means putting a factory-built gas fireplace where there wasn’t one before, whether that’s a chase on an exterior wall or a full masonry build-out in the living room. Gas fireplace installation in Miami typically runs $4,500 to $9,800, depending on whether you need framing, a gas line ran, or venting routed to a roof or side wall. This is one of the most involved jobs we do, and there are no corners worth cutting. Ashby Chimney Miami has installed gas fireplaces across Miami since 2002, and we use Copperfield and Olympia Chimney venting components that meet Miami-Dade’s stricter wind-load requirements. If it’s going to sit in a tropical storm, it has to be installed like it will.
Venting Design and Code
Direct-vent and B-vent fireplaces have different clearance requirements, and neither works correctly with a chimney that’s too small or too tight. We calculate the vent run before we sell the unit. Miami’s humidity and salt air mean the termination cap has to be stainless, not galvanized, or it’ll rust out in three years.
Clearances and Framing
The combustible clearance is non-negotiable, and we’re strict about it. We frame the chase correctly, install the firestop where the vent passes through the wall or ceiling, and leave the job with a firebox that operates the way the manufacturer intended. You get a written guarantee on the whole installation.
Gas Fireplace Maintenance
Gas fireplace maintenance is the annual or biannual service that keeps the unit lighting on the first try and burning with a clean, blue flame. We charge between $145 and $265 for gas fireplace maintenance in Miami, and we recommend doing it once a year if you use the fireplace more than a few times a season. It’s cheap insurance against a $400 control valve going bad because a dirty pilot burned it out. Ashby Chimney Miami has maintained gas fireplaces across the area since 2002, and the tech who shows up in Miami will have HeatShield and Gelco products on board for the jobs that need them.
What Gets Checked
We check the pilot, burner, valve, thermostat, remote, glass gasket, and venting on every maintenance visit. Each item gets a pass or fail on the written report we leave with you. If something fails, you get a written quote to fix it, and you decide whether it happens today or later.
Miami’s Salt-Air Factor
Homes near Key Biscayne, Miami Shores, and Palmetto Bay deal with salt-laden wind that accelerates corrosion on burner components and vent caps, which is why our Fireplace Repair in Key Biscayne includes extra attention to those parts. A gas fireplace five miles inland will often look better inside than one two blocks from the bay. We check for the corrosion that salt air tends to cause, and we tell you plainly what can wait and what can’t.
Wood Stove Installation
Wood stove installation requires a real chimney, a correctly sized flue liner, and clearances that most Miami homes weren’t built for. That’s the honest version. A wood stove installation in Miami typically runs $3,800 to $7,500 when a masonry chimney is already in place, and more if we need to build out a wall pass-through or run a full chimney system. Ashby Chimney Miami has done wood stove installation work since 2002, and we use DuraFlex liners and Olympia Chimney components that hold up to the heat these stoves produce. Nathan Corliss is direct about this: a wood stove is not a casual DIY weekend project, and the clearances are the difference between a safe stove and a structure fire.
Sizing the Stove to the Home
A stove that’s too big for the room will roast you out, and a stove that’s too small won’t heat anything beyond the sofa. We look at square footage, ceiling height, and window count before recommending a unit. The goal is a stove you’ll actually use, not a cast-iron ornament.
Chimney and Liner Requirements
South Florida humidity attacks a stove’s liner differently than any climate we work in, and we size the liner to the stove’s flue outlet, not to whatever is already there. An oversized liner lets the flue cool too much, and creosote builds up faster. We don’t send a stove out the door without the liner done right.
Brands We Service
Over the years we’ve repaired and installed a lot of units built around DuraFlex liners, and we stock their common connectors and components on our vans. That means when a liner joint fails or a cap needs replacing, the part is usually there the first day. DuraFlex is our go-to for relining masonry chimneys in Miami because it handles the heat and lasts in the humidity.
Copperfield makes solid fireplace components, and we’ve serviced their refractories, gas logs, and accessories in Miami homes for years. HeatShield is the product we use to repair cracked flue tiles without tearing out the whole chimney, and it’s saved Miami homeowners thousands compared to a rebuild. Whether you have Copperfield, DuraFlex, HeatShield, or any other make, we can help.

AfterSigns You Need a Pro Right Now
- You can smell gas when the fireplace is off. This is the one that should send you outside to call us. Even a faint gas odor means a leak somewhere in the line or valve, and that’s not something to wait on. Call (850) 787-8597 from outside the room, and we’ll walk you through what to do next.
- The glass is black with soot after each use. Soot on the glass means incomplete combustion, which is a venting or air-fuel ratio problem. It’s not just ugly; it’s a sign the burn is dirty, and a dirty burn means carbon monoxide is a possibility. We can fix the cause, not just clean the glass.
- The pilot light keeps going out, or the flame is yellow and lazy. A healthy pilot should be blue and steady. Yellow flames or a pilot that won’t stay lit usually means a blocked burner port, a failing thermocouple, or venting that isn’t drawing right. All three are fixable, and all three get worse if ignored.
- There’s visible cracking in the firebox or the masonry around the opening. Miami’s heat and humidity cycles stress the mortar and firebrick in older fireplaces. Cracks wider than a dime can let heat reach combustible material behind the firebox. We camera the crack before we recommend anything.
- The room smells smoky even when the fireplace isn’t in use. That’s backdrafting, and it’s a venting issue. It means the flue isn’t drawing correctly, and the air that should be going up is coming into your house instead. In a Miami house with hurricane windows sealed tight, this gets worse in certain weather. We diagnose it and fix it.
Our Process, Step by Step
- 1
You call, a person answers. No voicemail robots, no “we’ll get back to you.” You’ll talk to a real human at (850) 787-8597, 24/7. We’ll ask what the fireplace is doing, schedule a visit, and give you the arrival window in writing.
- 2
We show up in the window. Our techs are background-checked, uniformed, and will arrive when we said they would. They’ll lay down drop cloths, look at the unit, and run the diagnostics we need to understand the problem. If it’s a gas unit, we’re checking the gas pressure, pilot, thermopile, and flue draw.
- 3
You see the evidence. We’ll run a camera into the flue or into the firebox and show you, on a screen, exactly what we’re seeing. If there’s a crack, you’ll see the crack. If the liner is fine, we’ll tell you it’s fine. The written price we hand you is based on what the camera showed, not on what we think you’ll pay.
- 4
We fix it with the right materials. We repair with components from brands like DuraFlex, Copperfield, and HeatShield. Not parts that happen to be in the van. The repair is done to code, and we leave the area cleaner than we found it. You’ll have a written guarantee in hand before we pack up.
- 5
If it fails, we come back free. If a covered repair fails inside the guarantee period, we return and correct it at no charge. That’s the 365-Day Done Right Promise and the Kingswell Guarantee. It’s not an add-on, and it’s not a warranty you have to register for. It’s how Ashby Chimney Miami has done business since 2002.
How Much Does Fireplace Repair Cost in Miami?
A typical fireplace repair in Miami runs $195 to $550 for common gas unit issues like pilot assemblies, thermocouples, thermopiles, and burner cleaning. Gas valves and control modules push the price higher, usually $450 to $900. A chimney liner replacement sits between $2,500 and $5,000 depending on the height and whether we’re using a DuraFlex steel liner or a HeatShield resurfacing product. Full fireplace insert installation in Miami runs $3,200 to $6,800, and gas fireplace installation from scratch runs $4,500 to $9,800. Those are real ranges, not teaser numbers with fine print.
What moves the price in Miami specifically is access, age of the unit, and the condition of the flue. A two-story house in Kendall with a steep roof costs more than a single-story ranch in Hialeah Gardens, because the flue access is harder, but our Hialeah Fireplace Repair rates stay consistent regardless of home style. An older unit with proprietary parts from a brand that’s no longer in business will cost more, because we may have to fabricate an adapter. And if the flue needs relining before any insert or stove work happens, that’s a separate line item, and we’ll show you the camera footage that justifies it.
How to avoid overpaying: get a written quote before work begins, ask to see the problem with your own eyes, and be suspicious of anyone who gives a flat rate without looking at the unit. Our free estimate includes the diagnostic visit, the camera inspection, and a written price. You’re never obligated to say yes. If you’d rather think about it, the quote is yours to keep.

Fireplace repair is any work that restores a fireplace to safe, functional operation.

At Ashby Chimney Miami, we define it by the problem, not the price tag: we diagnose first, show you the evidence, and price the fix in writing.
Most gas fireplace repairs are completed in one visit, often within one to two hours. Liner replacements and insert installations take one to two days, depending on access and materials. We’ll tell you the expected timeframe along with the written price, so you know what to plan around.
Most fireplace repairs in Miami run between $195 and $550 for common gas unit issues, with bigger jobs like liner replacement or valve work running $450 to $5,000 or more.

We service most major brands and many that aren’t made anymore. Our techs work with components from DuraFlex, HeatShield, Copperfield, and others, and we keep common parts on the van. If your brand isn’t one we stock, we’ll source the correct part rather than making a substitute work.
If you smell gas, yes, that’s an emergency, and you should call us from outside the home right away at (850) 787-8597. We answer live 24/7.
