AfterHow Much Does Fireplace Services Cost in San Antonio?
Fireplace services in San Antonio typically run between $149 and $650 depending on what your fireplace needs. A standard chimney sweep and inspection usually costs $189 to $289, while repairs like firebox fixes, damper replacements, or flue liner work can push a bill to $900 or more. The good news: most jobs we quote fall in the $200 to $450 range, and you’ll always get a written price before any work begins.
At Hadley Chimney San Antonio, we’ve been serving San Antonio homeowners since 2003, and our pricing reflects what this market actually charges. No vague estimates, no door-surprise add-ons. Here’s the real breakdown for 2026, plus exactly what drives costs up or down in Bexar County specifically.
Fireplace Services Cost Breakdown (2026)
Here are the actual price ranges we quote in San Antonio, from basic sweeps to full liner replacements. These numbers come from jobs we’ve done across the city, from Alamo Heights to Stone Oak to Helotes. If you’re comparing quotes, use this as your benchmark.
| Service | Typical Cost Range | What It Includes |
|---|---|---|
| Chimney Sweep & Level 1 Inspection | $189 – $289 | Full flue cleaning, firebox debris removal, visual check of damper, cap, and exterior masonry |
| Level 2 Inspection (with camera) | $250 – $450 | Everything in Level 1 plus a video scan of the flue interior; typically required for home sales or after a chimney fire |
| Firebox Repair (minor cracks/mortar) | $250 – $550 | Refractory mortar patching, minor brick reset, heat-rated sealant work |
| Damper Replacement | $300 – $600 | Standard throat damper removal and new top-seal or throat damper install |
| Chimney Crown Repair/Rebuild | $500 – $1,100 | Removing cracked crown concrete, rebuilding with proper expansion joint, weather-sealing |
| Flue Liner Replacement (stainless, full reline) | $1,200 – $3,500 | DuraFlex or equal stainless liner, insulation, top plate, rain cap; cost varies by flue height and access |
| Gas Fireplace Service & Cleaning | $150 – $300 | Glass removal, burner cleaning, log repositioning, pilot/thermocouple check, gas valve testing |
| Chimney Cap Replacement | $200 – $450 | Standard stainless cap or custom multi-flue cap, including install |
Two things move the needle most in San Antonio: flue height and access. A two-story home in Stone Oak with a steep roof pitch costs more to service than a single-story ranch in Leon Valley, simply because the tech has to work higher and set up more safety equipment. And if your chimney hasn’t been cleaned in five years or more, expect the sweep itself to take longer; heavy creosote (the flammable tar buildup that makes chimneys a fire risk) requires extra passes and sometimes chemical treatment, which adds $50 to $100 to the base sweep price.
What Affects Fireplace Services Pricing in San Antonio
Every quote you get should explain why the price is what it is. Here’s what we look at when we price a job, and what you should ask any chimney company about.
- Age and condition of the firebox. San Antonio has thousands of homes built in the 1970s and 1980s, and firebrick from that era is often cracked or spalling by now. Patching hairline cracks runs cheap; rebuilding a firebox wall is a bigger job because it usually means removing and resetting brick, not just smearing on mortar.
- Flue liner material and damage level. If you have a clay tile liner and it’s cracked, you can’t just spot-fix it in most cases; clay tiles segment and shift. A stainless reline with a DuraFlex system is the long-term fix, and the cost swings based on how many feet of liner your chimney needs and how hard the flue is to access from the roof.
- Roof access and pitch. This is a big one in San Antonio. Some chimneys on steeply pitched roofs in Dominion or Terrell Hills require a safety anchor and extra setup time, which shows up as a modest line item. It’s not a surcharge to pad the bill; it’s that the tech physically needs additional safety rigging.
- Moisture damage already done. San Antonio gets intense spring storms, and the freeze-thaw cycles we see in January and February crack crowns and spalling bricks faster than in drier climates. If water has been getting in for years, you may need crown work and firebox repair and a new cap, which is why the initial sweep price can turn into a $900 repair ticket once we see the full picture. We’ll always show you photos before quoting that.
- Gas vs. wood-burning. Gas fireplaces are generally cheaper to service than wood because there’s no creosote removal. But gas units have their own failure points: thermocouples, gas valves, and log sets all wear out, and parts from brands like Copperfield or Gelco run $40 to $180 depending on the component.
- Who did the last repair. We see this constantly in San Antonio. A previous company patches a crown with the wrong mortar or installs a damper slightly off, and the “cheap” fix becomes an expensive one six months later. Our 365-Day Done Right Promise exists for exactly this reason; every repair carries a written guarantee, and if it fails, we come back free.
How to Save on Fireplace Services
The smartest way to save money on chimney work is to not skip the annual sweep. A $229 sweep catches a hairline flue crack before it becomes a $1,800 liner replacement. That said, here’s what else actually moves the number down.
- Book early in the season. Demand for chimney sweeps in San Antonio spikes hard from late September through January, as soon as the first cold front hits. Booking your sweep in August or September means you get your pick of appointment times and sometimes a lower rate since we’re not dealing with peak backlog. And no, we don’t charge more during high season; it just means you’ll wait longer if you call in December.
- Combine services. If you need a sweep plus a crown repair, pair them. The second service saves you a trip charge and setup time because the tech is already on your roof. Most companies, including us, price combined work lower than two separate visits.
- Ask about cap and liner brands up front. A generic stainless cap from a local supplier might be $30 cheaper than a Famco or Olympia brand cap. That $30 savings can mean rust streaks in two years. We use specific brands for a reason; ask your tech what they’re installing and why before you agree.
- Get the free estimate in writing. Every job we do includes a written price before work starts. No deposit, no surprise. Call (254) 276-4116 and we’ll send someone out to look, take photos, and hand you a price on the spot. If you don’t like it, you pay nothing and we shake hands and leave.
- Don’t defer gas fireplace maintenance. A $180 gas fireplace service now beats a $450 valve replacement later. Gas fireplace thermocouples and pilot assemblies are cheap to replace if caught early, but they can take out other components when they fail completely.
What Happens When You Book With Hadley Chimney San Antonio
Here’s what the process looks like, start to finish, because you shouldn’t have to wonder what a chimney company is going to do when they show up.
When you call (254) 276-4116, a live person answers. Not a voicemail loop, not a call center that transfers you three times. We book a specific arrival window and the technician shows up in a tracked vehicle, so you can see exactly when we’re pulling onto your street. That’s part of The Relay Visibility Guarantee, the standard we’ve operated under since joining the Relay Home Co. family.
On site, the tech introduces themselves, shows their background-checked ID, and puts on shoe covers before stepping inside. They’ll inspect the firebox, damper, flue, cap, and crown. You get shown photos of anything that needs work, on the spot, so you’re never guessing whether a recommendation is real. Then you get a written price. If you approve, the work happens same day in most cases. If you don’t, you owe nothing for the visit.
After the work is done, you get before-and-after photos and a digital invoice you can pay from your phone. Every repair includes a written guarantee. If it fails within 365 days, we come back and fix it free. That’s the 365-Day Done Right Promise, and it’s been part of how we operate since Cory Mitchell founded Hadley Chimney Sweep in 2003.
Why San Antonio Fireplaces Have Specific Issues You Should Know About
San Antonio’s climate does specific things to chimneys, and knowing this helps you understand what a tech is looking for.
The big one is humidity. We get Gulf moisture year-round, and that humidity seeps into brick and mortar. Then a January cold snap hits and any trapped moisture freezes, expands, and cracks the crown or spalls the brick face. Homes in Terrell Hills, Alamo Heights, and Monte Vista with older masonry see this constantly. The crown is the concrete slab that sits on top of the chimney, and its entire job is shedding water. When crown cracks open up, water gets behind the flue liner and starts working on the firebox from the inside.
Another San Antonio-specific factor: fireplaces in our market get used less than in northern cities. That might sound like a good thing for maintenance, but it’s actually the opposite. A chimney that sits unused for nine months accumulates debris, dust, and sometimes bird or squirrel nests (we pull more squirrel nests out of chimneys in Stone Oak and Helotes than anywhere else in Bexar County). A chimney that gets one fire in December and then sits all spring with creosote and ash is more likely to have corrosion and odor issues than one that gets regular use all winter.
And gas fireplaces: plenty of San Antonio homes were built with gas log sets in the 1990s and early 2000s, and those units are now 20 to 25 years old. Valve seals dry out, thermocouples fatigue, and burners rust. If your gas fireplace smells like rotten eggs when you turn it on, that’s a gas odorant and you should shut it off and call a professional. We’ll come check it, but don’t leave it running while you wait.
Gas Fireplace Repair Costs in San Antonio
Gas fireplaces have their own pricing landscape, so let’s break that out separately. Most San Antonio homeowners with gas fireplaces have either a prefab unit with a log set or a decorative gas insert.
- Pilot light won’t stay lit: This is usually a thermocouple or thermopile issue, and the part runs $30 to $80. Labor brings total cost to $150 to $250 in most cases.
- Burner replacement: Burners rust out on older units, especially in humid San Antonio summers. A replacement burner from a brand like Copperfield or Famco runs $120 to $350, plus install, putting the total at $280 to $550.
- Gas valve replacement: This is the more expensive repair, and it’s genuine safety equipment. A new gas valve with install typically lands between $400 and $800. If you smell gas or the valve sticks, don’t try to clean it yourself. Shut off the gas line to the fireplace and call us.
- Glass door or gasket replacement: Frameless glass panels on newer units crack from heat cycling. Replacement glass plus high-temp gasket runs $150 to $350.
One note on gas service: we test every gas connection with a leak-detection solution and do a full valve and pilot check as part of any gas fireplace service. That’s standard for us, not an upsell. It’s the same reason we use the $150 to $300 range for a standard clean-and-test; the gas system check is included.
What’s Included in a Standard Chimney Sweep in San Antonio?
A lot of people quote “chimney sweeps” at wildly different prices, so here’s exactly what you should expect for the $189 to $289 range in our market. If a quote is dramatically lower, ask what they’re leaving out. If it’s higher, ask what they’re adding.
- Flue cleaning: We run a wire or poly brush through the full flue length, sized to your flue diameter. This removes creosote and soot. If creosote is glazed (a hard, tar-like coating that happens with repeated low-temperature fires), we may need chemical treatment, which adds $50 to $100.
- Firebox cleanup: We remove ash and debris from the firebox and dispose of it. We also vacuum the smoke shelf, the area behind the damper where debris collects and blocks proper draw.
- Damper check: We open, close, and inspect the damper. A damper that’s rusted open is a huge energy leak in summer when your AC is running; a damper that’s frozen shut means smoke backs into the room.
- Visual exterior check: We look at the cap, crown, and exterior brick from the roof or ground (depending on access and roof safety). If we spot cracks or water staining, we’ll show you photos.
- Draft test: We light a small smoke test or use a draft gauge. You’d be surprised how often a chimney “works fine” but is actually drafting poorly due to a partially blocked flue or negative pressure in the house.
Every one of these steps has a purpose, and we document what we did with photos. Your invoice will show the checklist, not just the total. That’s the Relay Standard at work.
