One small part. Three big problems it keeps out.
The cap is the metal cover that sits over your flue opening at the very top of the chimney. It's one of the least expensive parts of the whole structure, and it does three jobs at once: it keeps rain out of the flue, it blocks birds, squirrels, and raccoons from nesting inside, and it stops stray sparks from landing on your roof.
Leave it off, or let a rusted one fail, and you invite all three back in. A missing cap is one of the most common (and most preventable) causes of chimney trouble in San Antonio.
Keeps Rain Out of the Flue
Water pouring straight down the flue rusts the damper, cracks the liner, and dampens the firebox. The cap stops it at the top.
Blocks Animals & Nests
Birds, squirrels, and raccoons love an open flue. A capped chimney with mesh keeps them (and the blockages they cause) out.
Stops Sparks From Escaping
The spark-arrestor mesh keeps burning embers from drifting onto your roof. Fitted and installed by certified & insured techs.
The Right Cap for Your Chimney
Flue count, opening size, and the look you want all decide which cap fits. We measure yours and install the one that's right, not the one that happens to be in stock.
Single-Flue Cap
The standard cover for one flue, sized to your opening and secured to keep rain, animals, and sparks out
Multi-Flue Cap
A single larger cap that covers several flues at once, ideal for chimneys with more than one liner up top
Custom Shroud
A tall decorative cover that dresses up the chimney top while it protects, built to match your home
Spark-Arrestor Cap
Built with the right mesh to stop burning embers from reaching the roof, important in dry Texas seasons
Draft-Correcting Cap
A specialty cap that helps a smoky, poor-drawing chimney pull properly when wind or downdraft is the culprit

Signs Your Chimney Needs a Cap
Cap problems are often something you hear or find inside, not just something you see up top. Recognize any of these? The estimate is free.
Scratching or Chirping in the Flue
Sounds of movement, scratching, or birds coming from the chimney mean an animal has moved into an open flue. A capped chimney with mesh keeps them out for good.
Debris in the Firebox
Twigs, leaves, nesting material, or acorns sitting in the fireplace fell straight down an uncapped flue. That debris is also a fire and blockage hazard.
Rain Sounds or Water Inside
Hearing rain hit the bottom of the fireplace, or finding a damp firebox after a storm, means water is pouring straight down an open flue, rusting the damper as it goes.
A Musty or Animal Smell
A damp, musty, or animal odor drifting from the fireplace often points to moisture or a nest inside the flue, both things a cap would have kept out.
A Rusted or Damaged Cap
If you can see the existing cap is bent, rusted through, or missing its mesh, it is no longer doing its job, and the flue is exposed again.
No Cap at All Up There
Look up, or check with binoculars. If the flue is a bare open hole with nothing over it, your chimney is completely unprotected from all three threats.
A cap is a small, same-visit fix. Going without one invites water damage, animal removal, and blockage, each of which costs many times more.

Sized to the flue, secured to stay put, and built to keep rain, animals, and sparks out for years. From standard covers to custom shrouds.
Every install is measured to your flue and documented, so you know it fits and it stays put.
How We Fit & Install Your Cap
A cap is one of the quickest jobs we do, but only when it is measured and secured right. Here is how it goes.
Measure the Flue, Not Guess It
A cap only works if it actually fits. We measure your flue opening (or openings) and check the crown it sits on, so the cap seats correctly instead of blowing off in the next storm. Call (726) 259-1693 or send the form for a free estimate.
Recommend the Right Cap
Single-flue, multi-flue, a custom shroud, or a spark-arrestor or draft-correcting cap, we match the type and material to your chimney and how you use it. You approve it before we order anything, in writing.
Install It & Secure It
We fit the cap and fasten it properly so it stays put through wind and weather, not wedged on to fall off later. Most caps are fitted and installed the same visit, and we clean up before we leave.
Protected & Warrantied
Rain, animals, and sparks are shut out, and the install is done by certified & insured technicians and backed by our 3-year workmanship warranty in writing. One small part, doing its three jobs for years.
A Cap Is Only as Good as the Install
The right cap wedged on wrong still blows off. Here is what makes ours stay put and keep working.
Measured & Secured
Sized to your exact flue and fastened to stay put through wind and storms, not a generic cap jammed on that lifts off the first bad night.
Materials That Last
Quality caps built to survive Texas sun and weather, not thin covers that rust through in a couple of years and leave the flue open again.
The Right Cap for the Job
Single-flue, multi-flue, shroud, spark-arrestor, or draft-correcting, we fit the type your chimney needs, not whatever happens to be on the truck.
Certified, Insured & Warrantied
All work by certified & insured technicians, backed by a 3-year workmanship warranty in writing. If it ever fails us, we come back and make it right.

"Solid experience from start to finish. Incredibly fast to respond, showed up right on time, and clearly knew exactly what they were doing, very knowledgeable crew. On top of the expertise, their pricing was highly affordable compared to the rates you see everywhere else these days. If you want a quick, smart, and reasonably priced chimney service, just call them."
"We actually got referred to this company by the previous owners when we bought our house, and they've been our go-to ever since. We do our annual maintenance checks with them every year to keep things safe, and they handle the full cleaning every few years when it's due. It's peace of mind knowing you have a reliable team you can trust year after year."
"I can't thank these guys enough. We noticed water staining on our ceiling after a heavy storm and panicked thinking about the repair costs.

If we had waited, we'd have been looking at tens of thousands in ceiling and flooring damage. Truly saved our home and our wallets."
"So glad I found this company! I had a super frustrating leak coming from my chimney, so I spent a couple of days shopping around and getting quotes.

The whole process was completely stress-free!"
