Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across San Marcos
Chimney sweep service in San Marcos typically costs between $189 and $329 for a standard cleaning and Level 1 inspection, with most jobs completed the same week you call. We cover every corner of San Marcos, from the older neighborhoods near Texas State University to the newer developments off Highway 123 and Wonder World Drive. A dirty chimney isn’t just about soot – it’s creosote, the flammable tar buildup that makes chimneys a fire risk, and San Marcos humidity makes it stick harder and build faster. Call (361) 603-5116 and a live person answers, day or night.
We’re Hadley Chimney Austin, and we send background-checked, uniformed technicians to San Marcos in a tracked arrival window – not a four-hour guess. You get a written price before anyone picks up a brush, and before-and-after photos on every job. When you book a Chimney Sweep with us, you’ll know exactly who’s coming, when they’ll arrive, and what they’ll find inside your flue before you spend a dollar beyond the sweep itself.
Why Hadley Chimney Austin Is San Marcos’s Preferred Chimney Sweep Company
Since 2003, Hadley Chimney Sweep has built trust by showing homeowners the evidence. Every San Marcos job includes camera-backed documentation before we recommend anything beyond a standard sweep. Cory Mitchell leads our team with the same expectation on every visit: if we can’t show you the problem on a screen, we don’t ask you to pay for the fix. That’s how we’ve earned a strong local reputation in San Marcos, where older brick chimneys and rarely used fireplaces invite exactly the kind of vague upsell we refuse to do.
San Marcos homeowners tell us the same thing again and again: another company quoted a liner replacement without ever putting a camera up the flue. That’s the industry’s worst habit, and we won’t do it. Nothing gets recommended without footage you can see. Our Chimney Sweep in San Marcos customers get that as a standing commitment, backed in writing.
We dispatch directly to San Marcos neighborhoods including the Blanco River corridor, downtown’s historic district near the Square, and the east-side subdivisions built in the 1960s and 1970s. Those east-side homes need particular attention because of what we know about their original clay tile flue liners – more on that below.
Every Chimney Sweep visit from Hadley is covered by The Relay Visibility Guarantee: live arrival tracking, before-and-after photo documentation, and a written price before work begins. Every repair carries our 365-Day Done Right Promise – a written guarantee on every job, plus a free second visit if the repair fails. That’s not a promotion. That’s how we work.
Styles & brands we work with
Chimney Services in San Marcos
Chimney Services in San Marcos cover the full lifecycle of a working chimney – sweeping, inspection, cap installation, crown repair, flashing, and flue resurfacing. Here’s what a typical San Marcos homeowner needs and what it costs.
Annual Sweep and Creosote Removal
Most San Marcos homes need a sweep once a year, especially if you burn wood more than a handful of times each winter. A standard sweep in San Marcos runs $189 to $259 and includes a Level 1 inspection. Creosote removal for heavier buildup – the kind San Marcos humidity tends to harden into tar – may add $40 to $80 depending on how much has accumulated.
Soot Removal and Fireplace Cleaning
Gas Fireplace Repair in San Marcos and fireplace cleaning runs $149 to $219 when paired with a sweep. Soot removal matters even for decorative fireplaces that rarely get lit. The humid subtropical air in San Marcos settles into the firebox and flue, turning light soot into an acidic mess that corrodes metal dampers and stains brick. If you’ve only burned a few duraflame logs in the last two years, you’d be surprised what comes out.

Chimney Sweep Certified in San Marcos
Chimney Sweep Certified means our technicians arrive with the training, tools, and camera systems to assess your San Marcos chimney properly – not just run a brush up and call it done. A certified sweep in San Marcos runs $189 to $329 depending on flue type and condition, and each visit includes the documentation that matters.
Level 1 and Level 2 Inspections
A Level 1 inspection in San Marcos costs $99 to $149 as an add-on and is included with every standard sweep. It covers the accessible parts of your chimney: firebox, damper, cap, and what’s visible from the roof. A Level 2 inspection runs $249 to $399 and includes a camera scan of the full flue interior – the only way to catch cracked clay tile liners, which we find often in east-side San Marcos homes built in the 1960s and 1970s.
Clay Tile Flue Assessment
If your San Marcos home has an original clay tile flue, we check it with a camera before we brush. Standard rods and brushes can’t crack a healthy tile, but a compromised one – already cracked from thermal shock – needs a resurfacing approach like HeatShield rather than a simple sweep. This is the nuance that protects your home and your wallet.
Trusted Brands We Service in San Marcos
We spec materials and repair systems from brands chimney professionals actually trust. That means HeatShield ceramic resurfacing for cracked clay tile flues, San Marcos Gelco service for chimney caps and chase covers, and Olympia Chimney components for prefabricated metal units common in newer San Marcos developments. We keep common parts stocked for fast turnaround on San Marcos jobs, so a straightforward cap replacement or damper repair doesn’t become a two-week wait. If your factory-built fireplace needs a specific replacement part, we’ll source it and show you the documentation before we install anything.

AfterCommon Chimney Sweep Problems We See in San Marcos Homes
- Cracked clay tile flue liners in east-side 1960s – 70s homes. Decades of sporadic hot fires after long disuse cause thermal shock, cracking the original clay tiles. These cracks hide behind walls, and only a Level 2 camera inspection reveals them. On a home near the east side, our tech found hairline cracks and spalling joints in a 1960s chimney whose owner had only burned occasional fires – we showed them the footage on our tablet and recommended HeatShield resurfacing rather than a full rebuild.
- Moisture-hardened creosote in rarely used fireplaces. San Marcos’s humid air gets into the flue and hardens creosote into a tar-like glaze. Standard brushing leaves this layer behind, and it still burns. We use the correct mechanical and chemical removal for third-degree glaze, then show you the before and after photos so you can see it’s actually gone.
- Crown and flashing failure on older brick chimneys. The older brick chimneys near downtown and the historic districts of San Marcos take a beating from humidity and rain. Cracked crowns and rusted flashing let water into the masonry, which accelerates spalling and flue damage. We check these on every sweep and recommend repair only with photos in hand.
- Rental properties needing compliance inspections. Many San Marcos rental homes require an annual chimney inspection to meet lease agreements and insurance requirements – even if tenants never light a fire. Landlords call us for Level 1 inspections that produce the documentation their insurer wants, no upsell attached.

FAQs About Chimney Sweep in San Marcos
Yes, many San Marcos landlords require one to satisfy lease and insurance terms, even for decorative fireplaces. The flue still collects debris, creosote from occasional fires, and moisture-related buildup in San Marcos’s humid climate. We document everything and give you a report your insurer accepts. Call (361) 603-5116 to schedule a Level 1 inspection.
Humidity absorbs into the porous flue surface and mixes with creosote, hardening it into a tar-like glaze that’s more difficult to remove and more likely to fuel a chimney fire. Even light seasonal use builds this layer faster in San Marcos than in dry climates. An annual sweep with proper mechanical removal keeps it from hardening into a hazard.
A standard brush won’t crack healthy clay tile. But if the tile is already cracked – common in San Marcos east-side homes where occasional hot fires after long disuse cause thermal shock – brushing can worsen the damage. We camera-check the flue before brushing so we know what we’re working with. If we find cracks, we’ll show you the footage and recommend HeatShield resurfacing.
Yes, a cap keeps rain, leaves, birds, and humid air out of the flue year-round. In San Marcos’s humid subtropical climate, an uncapped chimney absorbs moisture that accelerates creosote hardening and rusts metal dampers. Caps run $225 to $475 installed, and we’ll show you why yours matters before installing.
A Level 1 covers accessible components and is included with every sweep. A Level 2 adds a camera scan of the flue interior and costs $249 to $399. If you’ve never had your chimney inspected, own an older home with a masonry or clay tile flue, or just bought the house, get a Level 2 – it’s the only way to see hidden damage before it becomes a fire risk. Call (361) 603-5116 and we’ll help you pick the right one.
