Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across Rendon
Chimney repair in Rendon usually means fixing what Blackland Prairie clay has done to masonry, not what fire has done to flue liners. The soil under Rendon expands and contracts through every wet-dry season, and that movement cracks crowns, pulls flashing loose, and walks brick chimneys out of plumb. If you’re seeing water stains on the ceiling near the fireplace, grit on the hearth after rain, or a chimney that looks like it’s leaning slightly, call (830) 251-4560. We give every Rendon homeowner a written price before any work starts, and every repair carries a 365-day written guarantee.
Why Flint Chimney Sweep Is Rendon’s Preferred Chimney Repair Company
We’re part of Garrison Partners, founded in 2002, and every repair we do in Rendon follows The Garrison Standard: a written price delivered before the first tool comes off the truck, a written guarantee good for a full year, and a free return visit if a covered repair fails within that period. No exceptions, no handshake deal.
Rendon homeowners tend to be skeptical of chimney companies, and honestly, they should be. The industry has a habit of no-show appointments and price shifts at the door. Our technicians are background-checked and uniformed, and a live person answers our phone around the clock. When we say we’ll be at a house off Rendon Road or McAlister Road at a given time, that’s when we show up.
Hank Delano runs the crews that serve Rendon, and the repair work here leans heavily on masonry and water management. We stock the materials those jobs need, HeatShield crown repair material, Gelco flashing products, and Olympia Chimney caps, so turnaround stays tight for local customers.
Chimney Flashing Repair in Rendon
Chimney Flashing Repair in Rendon is one of the most common calls we make in this area, because Blackland clay doesn’t just crack slabs. It settles the ground under the chimney chase, which tugs the metal flashing where the chimney meets the roofline and opens small gaps for water. Once water gets between shingle and flashing, it tracks down into the chase and the ceiling below, and the damage compounds through every rain. A typical flashing repair in Rendon runs $450 to $950 depending on whether we’re resealing existing flashing or cutting it out and installing new metal.
Signs Flashing Has Failed
You’ll see water staining on the ceiling near the fireplace, peeling paint on the wall where the chimney passes through, or rust-colored streaks running down the interior of the flue during a rainstorm. Sometimes the flashing itself is visibly lifted at the corners. If you catch it early, sealing is often enough. If the metal is corroded or torn, replacement is the only honest fix.
What the Repair Involves
We pull back the surrounding shingles, inspect the underlayment, remove old sealant, and either reset the existing flashing or cut new step and counter flashing. Then we seal every joint and hand you a photo report showing what we found and what we did. The written price you approved before we started is the exact price on the invoice.
Chimney Crown Repair in Rendon
Chimney Crown Repair in Rendon addresses the concrete or mortar cap that sits on top of the chimney stack and keeps rain out of the masonry. On Rendon homes, the crown is the first thing to suffer when expansive clay shifts the structure. Hairline cracks smaller than the width of a thumbnail can open up in a single wet-dry cycle, and from there water works its way down through the brick, freezes on rare cold snaps, and spalls the face of the masonry. Crown repair in Rendon typically runs $600 to $1,300 depending on the size of the chimney and whether we’re resurfacing with a product like HeatShield or rebuilding the crown entirely.
Why Crown Cracks Show Up So Often Here
The soil under a Rendon slab moves more than people realize. A chimney that shifts a quarter inch may not look different from the street, but that’s enough to bend a rigid mortar crown past its tolerance. Add in a Texas gully-washer and the water follows every crack down. We see property after property where the firebox is spotless, the flue liner is clean, and the crown looks like a dried lakebed. That’s Blackland clay, not creosote.
When to Resurface vs. Rebuild
If the crown has shallow hairline cracks and the overall shape is sound, we clean out the cracks and resurface the crown with a flexible sealant that moves with the chimney. If the crown is broken, spalling, or pulling away at the edges, we form and pour a new crown with a proper drip edge to throw water off the brick. We’ll show you the camera footage before and after either way, so you can verify the work with your own eyes.
Trusted Brands We Service in Rendon
We stock and install parts from HeatShield, Gelco, and Olympia Chimney for Rendon customers, and we specify material by the job, not by margin. HeatShield handles crown resurfacing and flue-liner spot repair where the damage is localized. Gelco products seal flashing and penetrations on the rooftop side. Olympia Chimney caps and dampers replace rusted-out units that let rain and animals into the flue. If you want to look up a product’s spec sheet before you decide, we’ll tell you exactly what we’re using and why.
Common Chimney Repair Problems We See in Rendon Homes
- Crown and flashing failure from clay movement. Hairline cracks open on the crown, water tracks down the flue, and the chase mortar starts spalling while the firebox stays perfectly clean. This is the single most common Rendon repair request we run, and it has nothing to do with how often the fireplace is used.
- Intermittent burning that quietly stacks creosote. A lot of Rendon homes see a few December fires and then nothing until the next cold snap. Creosote from those fires sits on the flue liner at first-degree levels for years, and nobody sweeps because the fireplace still draws fine. The liner is the thing taking the hit.
- Draft problems from a shifted damper or cracked smoke chamber. A chimney that still pulls smoke upward can still be a carbon monoxide risk if the damper has shifted or the smoke chamber has cracked. The draft is there, but it isn’t routing gases the way it should.
- Spalling brick on the stack exterior. Once water has gotten into the brick from above, freeze-thaw cycles and general Texas humidity start flaking the face of the masonry. Left alone, spalling moves from cosmetic to structural, and the chimney needs partial rebuilding instead of a simple repoint.

FAQs About Chimney Repair in Rendon
Yes, and in Rendon it’s not usually about creosote. Your chimney is a masonry structure standing in shifting Blackland clay, and the crown and flashing take water damage whether you light a fire once a year or not. An inspection finds the problem you can’t see from the ground. Call (830) 251-4560 for details on getting one scheduled.
We’ll tell you straight, and we’ll show you the camera footage to prove it. Hairline crown cracks in a dry season can usually wait a few months if you’re watching the weather. But if water is already staining the ceiling or tracking down the flue, that’s a now problem. The photo report we hand you after every inspection is what you’ll use to make that call with real evidence instead of a sales pitch.
No. Third-degree creosote is a hard, glossy tar that a standard sweep brush will not remove, and a rotary cleaning alone may not be enough. That’s the stage where flue-liner repair or replacement becomes the honest conversation. We’ll put a camera down the flue and show you what is actually in there before recommending anything.
First we inspect, with a camera where the job calls for it. Then you get a written price with the scope spelled out. Once you approve it, we schedule the repair, show up inside the window we gave you, do the work, and hand over a photo report of the before-and-after. Every repair carries a 365-day written guarantee, and if a covered repair fails within the year, we return at no charge.
We do not promise same-day repair. Chimney work done properly requires an inspection, a written price, and a scheduled appointment. What we do offer is a live person answering the phone when you call (830) 251-4560, and scheduling that respects your time once the job is agreed.
