Chimney Sweep & Repair in San Antonio, TX
Your chimney is a hidden fire hazard — especially in San Antonio where fireplaces go unused for months and creosote quietly builds up. Our certified technicians sweep, inspect, and repair chimneys throughout San Antonio, Stone Oak, Alamo Heights, and surrounding areas.
San Antonio homeowners often overlook their chimney until something goes wrong — a smoky fireplace, a strange odor in summer, or worse, a chimney fire. At Sweeppy LLC, we believe prevention is always better than an emergency repair. Our certified chimney sweep technicians serve San Antonio, Stone Oak, Alamo Heights, Helotes, Boerne, and all surrounding Bexar County communities.
Chimney fires are more common than most people realize. The National Fire Protection Association (NFPA) reports that heating equipment — including fireplaces and chimneys — is the second leading cause of home fires in the United States. In San Antonio, where fireplaces often sit unused for 6–8 months out of the year, creosote and debris quietly accumulate inside the flue. When the fireplace is finally lit in the fall, that buildup becomes a serious fire hazard.
Creosote is a dark, tar-like substance that forms when wood smoke condenses inside the chimney flue. It comes in three stages: Stage 1 (light, flaky deposits), Stage 2 (harder, tar-like coating), and Stage 3 (glazed, extremely flammable). Stage 3 creosote is the most dangerous and requires specialized removal techniques. Our licensed technicians are trained to identify and safely remove all three stages of creosote buildup.
A standard Sweeppy chimney sweep includes a thorough cleaning of the firebox, smoke chamber, and flue liner — plus a Level 1 inspection to check for cracks, blockages, and structural issues. We use professional-grade HEPA vacuum equipment and drop cloths to ensure your home stays clean throughout the process. Before we leave, we walk you through our findings and provide a written report.
Beyond standard cleaning, Sweeppy offers a full range of chimney repair services. Chimney caps prevent animals and debris from entering the flue — a common problem in San Antonio where birds and squirrels frequently nest in unused chimneys. Chimney crown repair seals the top of the masonry chimney to prevent water intrusion, which is especially important during San Antonio’s intense spring storm season. Flashing repair addresses leaks at the point where the chimney meets the roof. And if your flue liner is cracked or damaged, we offer liner installation and repair to restore safe venting.
For homebuyers and sellers in San Antonio, a Level 2 chimney inspection is required before transferring ownership of a property with a fireplace. This inspection includes a video camera scan of the entire flue liner to identify hidden cracks, blockages, or damage that cannot be seen with the naked eye. Sweeppy performs Level 2 inspections throughout San Antonio and Bexar County.

Frequently Asked Questions
Why San Antonio Homeowners Need Annual Chimney Sweeping
San Antonio’s mild winters mean most homeowners use their fireplace only a few months per year — but that’s still enough for creosote to build up inside your flue. The NFPA recommends annual chimney inspections and sweeping regardless of how often you burn.
Whether you’re in Stone Oak, Castle Hills, Helotes, Shavano Park, or Alamo Heights, Sweeppy LLC provides certified chimney sweep services throughout San Antonio and the surrounding areas.
Common signs your San Antonio chimney needs service:
- Dark staining around the fireplace opening
- Strong smoky or musty odor when fireplace is not in use
- Smoke entering the room when you light a fire
- It’s been more than 12 months since your last inspection
Our chimney sweep service includes a Level 1 inspection at no extra charge. We photograph inside the flue before and after so you can see exactly what was removed.

Chimney Services We Provide in San Antonio
From a routine sweep to caps, liners, leaks, and waterproofing — one licensed, insured, owner-operated crew for your whole chimney. Owner Nathan is on every job.
Chimney Cap Repair & Installation
A chimney cap keeps rain, debris, and animals out of your flue while letting smoke escape — the best prevention against leaks and nesting. We repair and install stainless steel chimney caps in San Antonio, from $249.
Chimney Liner Installation & Relining
The flue liner shields your home from heat and combustion gases and is essential for safe operation. We install new chimney liners and reline damaged ones — sizing and materials vary, so you always get an exact quote first.
Chimney Flashing & Crown Repair
Flashing (where the chimney meets the roof) and the crown (the concrete cap on top) are the two most common sources of a leaking chimney. We repair and seal both to stop water damage. Crown repair starts at $349.
Chimney Waterproofing
San Antonio brick and mortar are porous and soak up water, which leads to spalling and interior leaks over time. A breathable waterproof sealant keeps water out while letting the masonry breathe.
Creosote Removal
Creosote is the flammable residue that builds up inside your flue every time you burn — the leading cause of chimney fires. Our sweep removes it down to the walls; a sweep plus Level 1 inspection is a flat $144.
Fireplace & Animal Services
We also handle gas fireplace repair & service and chimney animal & bird removal — nest removal, sweep, and a cap to keep them out for good.
Common Chimney Questions
How much does a chimney cap cost in San Antonio?
Chimney cap installation starts at $249. A stainless steel cap with a mesh guard keeps rain, animals, and embers out of your flue while letting smoke escape — the single best prevention against chimney leaks and animal entry.
Do you install and reline chimney liners?
Yes. The flue liner shields your home from heat and combustion gases and is required for safe operation. We install new liners and reline damaged ones; because sizing and materials vary, you get an exact quote before any work begins.
Why is my chimney leaking when it rains?
It is almost always one of four things: failed flashing where the chimney meets the roof, a cracked crown (the concrete cap on top), a missing or damaged chimney cap, or porous brick soaking up water. Sweeppy repairs and seals all four — book an inspection and we will pinpoint the source.
How often should a chimney be inspected in San Antonio?
At least once a year — the NFPA recommends an annual chimney inspection — and swept whenever creosote has built up. Sweeppy’s chimney sweep plus a Level 1 inspection is a flat $144.
Is it safe to use my chimney?
If it has not been swept and inspected in over a year, have it checked before your first fire of the season. A blocked flue, an animal nest, or heavy creosote buildup is both a fire and a carbon-monoxide risk. A $144 sweep and Level 1 inspection confirms it is safe to burn.
