Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in San Marcos, TX
Oakgrove Chimney Sweep handles chimney repair, sweeping, and dryer vent work across San Marcos, and most calls start with cracked masonry or a flue that hasn’t been looked at in years. What makes San Marcos different is the housing spread: century-old bungalows near the courthouse square with original soft-red brick sit just miles from 1990s tract homes with prefab metal flues, and each requires a completely different diagnosis and tool set. If you need chimney repair, call (866) 472-2513 for a free estimate.
Why San Marcos Homes Are Different
San Marcos sits in a narrow transition zone where the Edwards Plateau’s limestone hills meet the Blackland Prairie, and that geology shows up inside chimneys. Older homes near downtown and along the San Marcos River often have chimneys built from local Edwards limestone rubble. That stone spalls over decades of humidity and freeze-thaw cycling, and the mortar joints erode until the structure shifts. Before any meaningful cleaning happens, that masonry needs repointing, which is a repair conversation, not a sweep conversation.
The newer subdivision homes in Sunset Oaks and Willow Creek are a different animal. Many were built in the 1980s and 1990s with prefab metal fireplaces and chase-style flues. San Marcos’s humid subtropical climate doesn’t punish these with heavy heating cycles the way a northern winter would, but the humidity accelerates creosote breakdown and rust in prefab components. Add spring live oak pollen and leaf litter that packs flue caps and spark arrestors, and you get a recurring clog pattern that most homeowners only notice when smoke backs up into the living room. Student rental turnover near Texas State adds another layer: chimneys in leased houses often go years without any service until a landlord or tenant finally calls.
Styles & brands we work with





Our Main San Marcos Services
Two jobs dominate the phones in San Marcos: routine chimney sweeping and dryer vent cleaning. Both are fire-safety services at their core, and both get overlooked in rental-heavy neighborhoods where maintenance responsibility gets blurry.
Chimney Sweep in San Marcos
A sweep in San Marcos means more than running a brush up a flue. We remove creosote and soot, clear out live oak leaves and acorns from caps and spark arrestors, and run a camera inspection to see what’s actually happening inside the liner. In older homes near the river, we frequently find spalled limestone that needs repointing before the flue is safe to use. Full details are on our Chimney Sweep in San Marcos page, including what gets inspected and what the camera report covers.

Dryer Vent Cleaning in San Marcos
Dryer vent cleaning gets filed under laundry, but it’s a combustion-pathway problem. Lint accumulates inside the vent run, restricts airflow, and the dryer motor works harder while heat builds up. In San Marcos rental homes especially, a vent might not have been cleaned since the house was built. Our team treats this as a fire-safety service, not a side errand, because the same airflow and exhaust principles govern chimneys and dryer vents. See the Dryer Vent Cleaning in San Marcos page for what we inspect and how the cleaning is documented.

Chimney Repair in San Marcos
Chimney repair in San Marcos usually comes down to one of two problems: old masonry degrading from Edwards limestone spalling and mortar erosion, or prefab flue components rusting out from years of humidity exposure. In the older bungalows near downtown, we see crowns cracked from decades of Texas sun and shifting foundation soil. In the 1980s and 1990s subdivisions east of I-35, we see chase covers and caps corroded to the point where water enters the flue during spring storms. Oakgrove Chimney Sweep repairs what we find, and we can handle the full scope without handing you off to a third party. Visit our Chimney Repair hub for the full breakdown of our repair methods.
Chimney Cap Installation
Signs you need it
You hear birds or animals inside the flue, or you see twigs and nesting material packed around the top of the chimney.
What it costs in San Marcos
A standard cap installation runs $300 to $500, with custom sizing on older San Marcos brick chimneys pushing toward the top of that range.
How we do it
We measure the flue opening, select a Gelco or Famco cap sized for the specific liner dimensions, and secure it with mechanical fasteners rated for Texas wind gusts.
Chimney Flashing Repair
Signs you need it
Water stains appear on the ceiling near the chimney or along the wall where the chimney passes through the roofline after rain.
What it costs in San Marcos
Flashing repair typically runs $400 to $700, depending on whether we’re re-sealing existing flashing or cutting and installing new metal.
How we do it
We remove the old flashing, inspect the surrounding roof decking for rot, and install new step and counter flashing with proper overlap before sealing the transition.
What Chimney Repair Costs in San Marcos
| Item | Typical range in San Marcos |
|---|---|
| Chimney cap installation | $300 – $500 |
| Chimney flashing repair | $400 – $700 |
| Chimney crown repair | $350 – $650 |
How do I know if my chimney needs repair or just a cleaning?
A camera inspection tells us. We look at the liner surface, the mortar joints, and the flue cap condition. If the liner is intact and the masonry is sound, a sweep is enough.
Can deteriorated limestone masonry be repaired, or does it need rebuilding?
Repointing works when individual stones are stable but the mortar is crumbling. If the limestone itself has spalled badly, a partial rebuild may be necessary. Call (866) 472-2513 for an evaluation.
Brands We Service in San Marcos
We stock and install components from HeatShield, Gelco, Olympia Chimney, and Famco, the same professional trade brands chimney contractors use rather than hardware-store substitutes. Parts for common San Marcos repair jobs are typically on hand in our service truck, so repairs don’t stall waiting for shipping from Dallas. See our brands for the full list.

Prices move within these ranges based on chimney height, roof pitch, and the condition of what we find behind the first layer.

FAQs About Chimney Company in San Marcos
Most San Marcos appointments can be scheduled within a few days, depending on the season. Fall and early winter fill up quickly because that’s when homeowners start using fireplaces again. Call (866) 472-2513 to get on the schedule.
Most routine sweeping, cap installation, and flashing repair does not require a city permit. Structural rebuilds or liner replacements may fall under San Marcos building code requirements, and we’ll handle that paperwork if it applies to your job.
Can you inspect a chimney in a house I’m buying in San Marcos?
Yes. We perform camera inspections for real estate transactions and provide a written report with photos. Given the age range of San Marcos housing, most buyers benefit from knowing whether the masonry flue is unlined or the prefab components are rusted before closing.
