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 Denton
Chimney repair in Denton usually costs between $275 and $2,800 depending on what’s actually wrong, and most jobs are done within one visit. The real question is whether you need a repair at all, or whether a sweep and inspection would put the problem to rest. That’s the answer we give every homeowner in Denton before a single tool comes off the truck.
We work throughout Denton, from Southridge and Idiot’s Hill down to the neighborhoods off Teasley Lane and the older homes near the square. If you’re seeing water stains on the ceiling, hearing animals in the flue, or noticing mortar crumbling off the crown, call us at (830) 251-4560 for a written, no-pressure estimate. We schedule by appointment, not by emergency, and we never leave a mess behind.
Why Flint Chimney Sweep Is Denton’s Preferred Chimney Repair Company
Flint Chimney Sweep has been in business since 2002, operating under The Garrison Standard as part of the Garrison Partners family of independently owned chimney service companies. Hank Delano leads our repair and inspection work across the Denton area. The rule is simple: every job gets a written price before any work begins, and every repair carries a written guarantee valid for one full year.
Denton homeowners tend to ask the same two things before they book: who is showing up, and what exactly is covered. The answer is a background-checked, uniformed technician, a 365-Day Done Right Promise on every repair, and a free second visit if a covered repair fails within that year. No charge, no argument.
Our phones are answered by a live person around the clock, not a voicemail tree. If you call at six in the morning or ten at night because a raccoon just fell through the damper, you’ll talk to a person who can schedule the visit. We know that sounds simple. That’s the point.
We work in Denton because Denton is where the work is: freeze-thaw cycles, hail, and older masonry. Our Chimney Repair team handles flashing, crowns, repointing, and waterproofing across the city, and we carry parts locally so you’re not waiting a week for a cap or a section of flue liner.
Chimney Flashing Repair in Denton
Chimney Flashing Repair is one of the most common jobs we book in Denton, and it’s usually the difference between a chimney that leaks and one that doesn’t. Flashing is the metal strip that seals the seam where the chimney meets the roofline. When wind and hail work it loose, water finds the gap and follows the brick down into the attic. In Denton, that happens every spring and again in the fall when the storms roll through.
A standard flashing repair in Denton typically runs $400 – $900, depending on how much of the existing flashing is salvageable and whether the surrounding roofing felt needs work. We’ll always bring you photos from the roof before we quote the repair, so the number on the invoice matches what you saw with your own eyes. If the flashing is just lifted at a corner, the repair may be on the lower end. If hail has deformed the whole assembly, it’s a bigger job, and it’s also the kind of job an insurance adjuster should see.
What We Check
We pull the shingles back at the transition point, inspect the base flashing and counterflashing, and photograph every seam. If the leak has been going on for a season, we also check the roof deck underneath for rot before we reseal anything.
Hail Damage Notes
Denton sits in a hail alley. You may not see the damage from the ground, but a quick look from the ladder will show pockmarks and lifted edges. We recommend documenting everything with photos, and we’ll hand you a copy so you can file the claim accurately if you need to.
Chimney Crown Repair in Denton
Chimney Crown Repair in Denton is driven by one thing: north Texas freeze-thaw cycles. The crown is the poured concrete cap that sits on top of the chimney and keeps water from running down the inside of the brick. When water seeps into hairline cracks and freezes, the crack widens. Repeat that over ten or twenty Denton winters and you get a crown that looks like a jigsaw puzzle and sheds spalled brick onto the roof.
Crown repair in Denton typically runs $650 – $1,800. A minor crack can sometimes be sealed with a quality crown coat. A crown that has delaminated or shifted needs to be rebuilt. We use HeatShield crown repair systems and professional-grade concrete mixes rated for exterior exposure, not quick patch products that fail after one season. The written price covers the exact scope we photograph, and nothing gets added to the invoice later.
Cracked vs. Spalled
A cracked crown can often be repaired. A spalled crown, where chunks of the surface have fallen clean off, usually needs a partial rebuild. We’ll tell you which one you have, and we’ll show you the camera images to prove it.
Waterproofing After Repair
Once the crown is sound, we usually recommend chimney waterproofing on the brick below it. Denton’s clay brick is porous, and once the crown is sealed, the next leak path is the brick itself. A breathable waterproofing treatment keeps water out without trapping moisture inside the masonry.
Trusted Brands We Service in Denton
We work with professional-grade chimney materials, and the brands we name are the ones we actually stock and install for Denton customers. For flue relining, we use DuraFlex stainless liners, which handle the high heat of a Texas fireplace and resist the corrosion that comes from wet chimneys. For crown and chase-top work, we use HeatShield, a ceramic sealant system rated for exterior freeze-thaw exposure. We also carry Copperfield caps and accessories, which means a simple cap replacement in Denton doesn’t have to wait on a parts order. Using named brands isn’t a marketing line. It means you can look up the material yourself and verify what went into your chimney.
Common Chimney Repair Problems We See in Denton Homes
- Freeze-thaw mortar failure: Denton’s winter temperature swings, from below freezing to the 60s within days, crack mortar joints and chimney crowns faster than the clay-heavy soils settle foundations. We see more repointing jobs in February and March than any other season.
- Storm-damaged flashing and caps: Spring winds and hailstorms routinely dislodge chimney caps and peel flashing away from the roofline. The damage shows up later as rusted dampers, wet flue liners, and ceiling stains near the fireplace.
- Raccoon and bird blockages: Spring is nesting season in Denton, and an uncapped or loosely capped chimney is an open invitation. A blocked flue is not just a nuisance; it is a carbon monoxide hazard, and every animal removal we do ends with a proper cap installation.
- Spalled brick on older homes near the square: The historic masonry around downtown Denton and older neighborhoods was built long before modern sealers existed. Decades of water intrusion cause the brick face to pop off in layers. Repointing and brick replacement are standard here, and we match the mortar color as closely as the existing material allows.

FAQs About Chimney Repair in Denton
A Denton chimney needs a Level 2 inspection with a camera whenever the home changes ownership, after a major weather event like a hailstorm, or whenever you suspect animal entry. For routine maintenance, once every two to three years is usually sufficient unless you burn wood daily during the winter. If you hear scratching, smell dampness, or see water stains near the chimney, don’t wait for the schedule, just book the inspection. The camera sees what a visual check misses. Call (830) 251-4560 to set one up.
First-degree creosote is a fine black soot that brushes off easily and is normal in any wood-burning chimney. Third-degree creosote is a hard, glazed tar that forms when fires burn cool and damp, and it is the form most responsible for chimney fires. Denton’s relatively high humidity and the heavy reliance on oak and hickory in north Texas make third-degree buildup more common here than in drier western parts of the state. If a sweep reveals glaze, the fix may involve chemical removal or a liner evaluation, and you want that caught before it becomes a burn hazard.
A cracked crown can sometimes be patched, but the patch has to be a bondable, exterior-rated material like HeatShield, not a hardware store caulk. Hairline cracks under a quarter inch are candidates for sealing. Wider cracks, delamination, or spalling mean the crown has already failed structurally and patching it will buy you months, not years. We’ll tell you plainly which category yours falls into, and the written estimate will say exactly what’s included. Call (830) 251-4560 for a camera look at the crown.
We don’t promise same-day repair, and you should be wary of anyone who does. A proper repair needs a dry chimney, a camera inspection, and materials that bond correctly. Rushing any of those steps is how you end up redoing the job. What we do offer is prompt scheduling for Denton addresses, a written price before work starts, and a one-year guarantee on everything we repair. If the repair fails within the year, we return at no charge.
After a Denton hailstorm, look for lifted or dented flashing at the chimney-roof junction, check for ceiling stains inside the house within a few weeks of the storm, and peek into the attic for daylight at the chimney chase. Hail damage to flashing often doesn’t leak immediately; it leaks after the next heavy rain. That’s why we recommend a roof-level camera inspection after any significant hail event in Denton, and we document everything so you can file an insurance claim accurately.
