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 Onion Creek, TX
Chimney repair in Onion Creek usually comes down to one of two jobs: replacing a rusted prefab cap or chasing down a leak around the flashing on a builder-grade firebox. We’ve worked this area since 2017, and what we see most often isn’t dramatic masonry failure. It’s neglected factory-built chimneys from the 2000s and 2010s that were never inspected because homeowners assumed prefab meant maintenance-free. Oakgrove Chimney Sweep handles the full scope: we sweep it, diagnose it, and repair what we find. Call (866) 472-2513 when you’re ready for a straight answer about your flue.
Why Onion Creek Homes Are Different
Onion Creek’s housing stock runs mostly 1990s through 2010s suburban production homes, brick veneer on slab. What that means for chimney work is specific: most fireplaces here are prefab metal fireboxes and direct-vent inserts, not full masonry chimneys with clay tile liners. The flues are short, often offset, and factory-built. When something goes wrong, it’s usually the cap rusting through, the flashing pulling away at the roofline, or a liner joint separating inside the chase.
Central Texas heat and humidity do their own kind of damage. Fireplaces sit idle for most of the year in Onion Creek, which gives creosote time to harden and pests time to move in. We routinely pull bird nests, wasp nests, and leaves out of flues that have barely been burned. Homeowners are often surprised, because a fireplace that gets lit four times a year still has a chimney that’s exposed to weather 365 days a year. Your flue is a combustion system, whether it’s masonry or prefab. In this part of Austin, the prefab ones are the majority, and they need annual inspection just like their older counterparts in South Austin.
Styles & brands we work with
Our Main Onion Creek Services
Most calls we get from Onion Creek homeowners start with one of two concerns: a chimney that hasn’t been swept since they moved in, or a dryer vent they’ve never thought about. Both are fire-safety issues, and both are services we perform as combustion-pathway specialists.
Chimney Sweep in Onion Creek
Sweeping an Onion Creek fireplace is different from sweeping an older masonry chimney. These prefab units have shorter, offset flues that collect creosote in places a brush can’t always reach without the right technique and tools. Because fireplaces here sit idle most of the year, we’re also checking for pest intrusion and moisture damage at the cap and chase top, not just soot. The annual sweep is the diagnostic: it’s how we catch a cracked firebox panel or a deteriorating liner joint before it becomes a repair bill. Read more on our dedicated Chimney Sweep in Onion Creek page.
Dryer Vent Cleaning in Onion Creek
Dryer vents in Onion Creek production homes tend to be long, routed through interior walls or up through the roof, and rarely cleaned. Lint builds up, airflow drops, and the dryer runs hotter and longer. We treat dryer vent cleaning as a fire-safety service, the same way we treat chimney sweeping, because the failure mode is the same: accumulated combustible material in an exhaust pathway. Our technicians understand combustion and airflow, not just ducts. See the full scope on our Dryer Vent Cleaning in Onion Creek page.

Chimney Repair in Onion Creek
Chimney repair in Onion Creek usually comes down to this: the firebox and flue were installed when the house was built, nobody has touched them since, and now something is rusted, cracked, or leaking. We see it on both the 2000s-era golf-course homes and the newer greenbelt builds. The repair work here is centered on prefab chase tops, caps, and flashing rather than repointing brick. Nothing gets recommended without camera evidence, and we repair what we find, which is the whole point of calling a company that handles Chimney Repair rather than just sweeping.
Chimney Cap Installation
Signs you need it
You have an open flue with no cap, or the existing cap is rusted through and letting rain, birds, and leaves into the chase.
What it costs in Onion Creek
Chimney cap installation in Onion Creek typically runs $125 to $375 depending on the flue size and whether it’s a standard single-flue cap or a custom chase cover.
How we do it
We measure the flue or chase top, match the cap to the existing termination, secure it with mechanical fasteners rated for the application, and verify the flue still drafts correctly afterward.
Chimney Flashing Repair
Signs you need it
You see water staining on the ceiling near the fireplace, damp drywall around the chase, or rust streaks running down the exterior siding below the roofline.
What it costs in Onion Creek
Chimney flashing repair in Onion Creek typically runs $350 to $575 depending on access, roof pitch, and whether the old flashing can be reused or must be removed and replaced.
How we do it
We pull back the affected shingle course, remove the failed flashing, install new step and counter-flashing sealed with a polyurethane sealant, and confirm the water path is broken before we leave the roof.
What Chimney Repair Costs in Onion Creek
| Item | Typical range in Onion Creek |
|---|---|
| Chimney cap installation | $125 – $375 |
| Chimney flashing repair | $350 – $575 |
| Chimney crown repair | $200 – $450 |
Do I really need a cap on a prefab chimney?
Yes. The chase top on an Onion Creek prefab chimney is exposed metal, and without a functional cap, rain goes straight down the flue into the firebox. Rust follows, and so do birds and wasps. A cap is the cheapest repair you’ll ever do on that system.
Can you repair a prefab chimney or just replace it?
It depends on what we find in the camera inspection. Caps, flashing, chase covers, and some liner components are replaceable. If the firebox itself has failed, replacement is the only safe option. We’ll show you the footage either way. Call (866) 472-2513 to schedule an estimate.
Brands We Service in Onion Creek

What pushes price up in Onion Creek is access. Steep rooflines on two-story production homes and tight chases on golf-course lots make ladder work slower and material staging more difficult. The price we quote over the phone is the price you pay, and we walk the quote through with you before any work starts.

What Onion Creek Customers Say
"Fireplace had never drawn properly since we moved in. He found the damper was only opening halfway due to a bent linkage and fixed it in ten minutes."
— Dustin Barrett"Drop cloths everywhere, HEPA vac, and not a speck of soot on the carpet. I'd been dreading the mess for nothing."
— Steve Doyle"Creosote buildup was worse than I realized. He measured it, showed me the glazing on the flue with the camera, and was honest that we were closer to a chimney fire than I wanted to hear."
