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 Glenn Heights
Chimney repair in Glenn Heights, TX typically runs $275 – $1,800 depending on what’s failed, and most jobs are diagnosed same-day with a camera inspection. Flint Chimney Sweep has been part of the Garrison Partners family since 2002, and we put a written price in your hand before any work starts. If you’re seeing cracked brick, water stains on the ceiling near the flue, or rust on the firebox, call (830) 251-4560 and we’ll get a uniformed, background-checked tech out to your Glenn Heights home, fast.
Glenn Heights sits right on the Blackland Prairie, and that clay soil is the reason we stay busy here. More on that below. The short version: your chimney moves more than you think, and what looks like a cosmetic crack is often the first sign of a water-intrusion problem that gets worse every freeze-thaw cycle.
Why Flint Chimney Sweep Is Glenn Heights’s Preferred Chimney Repair Company
Most Glenn Heights homeowners we meet have been burned before, not by their chimney, but by a chimney company. The tech shows up late, names a price, then finds another $900 in “unexpected damage” after the first brick is pulled. We don’t work that way. Under the Garrison Standard, our techs deliver a written, line-itemed price before any tool leaves the truck. The number you approve is the number on the invoice. No exceptions.
We carry a 365-Day Done Right Promise on every repair. If a covered repair fails within a full year of the service date, we return at no charge. No argument, no second invoice, no phone tag. That guarantee is written on every repair order we issue in Glenn Heights, whether it’s a flashing repair near Danieldale Road or a full crown replacement off Ovilla Road.
Our phones are answered by a live person around the clock. You won’t get a voicemail tree at 7 p.m. on a Sunday when you’re staring at a water stain spreading across your ceiling. And when the tech arrives, you’ll know who’s walking through the door: uniformed, background-checked, and carrying the exact equipment needed for the job you scheduled.
We’re not a franchise with a rotating cast. Hank Delano runs a tight crew, and every tech we dispatch to Glenn Heights carries the same camera inspection gear, the same warranty paperwork, and the same instruction: document everything, show the customer, explain plainly. If we can’t justify a repair with camera evidence, we say so.
Chimney Cap Replacement in Glenn Heights
Chimney cap replacement in Glenn Heights is one of the most frequent repairs we perform, and the reason is almost always the same: the cap is letting water in, or it’s rusted past the point of sealing. A failed cap is an open invitation. Rain drops straight down the flue, rusts the damper, streaks the firebox, and eventually soaks into the smoke chamber masonry. In Glenn Heights, a standard cap replacement with a Copperfield or Gelco unit typically runs $325 – $650 installed.
We recommend caps with a full-formed hood and mesh sides, not the cheap slip-in kind box stores sell. The hood sheds rain, the mesh keeps out birds, squirrels, and leaves, and a properly seated cap with a solid collar stops most of the water damage we see in Glenn Heights flues.
Signs your cap has failed
Rust streaks running down the exterior brick below the cap. A damper that feels stiff or won’t seat fully. Water pooling in the firebox after heavy rain. Small animal sounds in the flue, a sure sign something is nesting where the cap used to protect.
What a proper cap replacement includes
We remove the old cap, inspect the flue tile or liner top, then fit a cap that matches the flue’s inside and outside diameter, not a generic one from a big-box shelf. The cap is mechanically secured, then sealed with a high-temperature, water-resistant sealant. You get a photo report showing the before and after.
Chimney Liner Installation in Glenn Heights
Chimney liner installation in Glenn Heights means replacing or installing the actual flue liner that carries smoke and combustion gases out of your house. When a liner cracks, you’re not just losing draft; you’re giving heat and carbon monoxide a path into the framing around your chimney. A typical stainless flex liner installation with a DuraFlex system, sized and insulated for your flue, runs $1,200 – $2,600 in Glenn Heights, depending on run length and access.
The pipes and fittings we install are named-spec DuraFlex, Gelco, or Olympia Chimney, never whatever’s on sale this week. Our spec sheet goes with the job. The liner is sized to the appliance, not guessed at, and we run a full camera verification after installation so you can see the connection is continuous from collar to cap.
When a liner replacement is the right call
If your chimney was built for a wood-burning fireplace and you’ve switched to a gas log set or a high-efficiency furnace, the original clay tile liner is often oversized or deteriorated, and that’s a code and safety problem. Hairline cracks that appear in a camera inspection are a warning sign, not always an emergency, but they don’t self-heal. We’ll show you the footage and tell you plainly: fix it now, or watch it.
What the installation actually involves
We measure the flue with a camera and laser, not a tape measure held at the roof. The liner is lowered from the top or pulled from the bottom depending on access, then insulated where the clearances demand it. The top plate and cap are sealed, the appliance connector is secured, and we take a final camera pass before we call the job done.
Trusted Brands We Service in Glenn Heights
We stock common repair parts for Glenn Heights jobs, and when a liner or cap has to be ordered, we order directly from the trade suppliers we’ve used for years: DuraFlex for flex and rigid liner systems, HeatShield for ceramic repair coating, Gelco and Olympia Chimney for caps and chase covers, Famco for fans and dampers. We service and install these brands because they hold up to North Texas weather, not because they’re cheap. If your existing cap or liner is still under manufacturer warranty, we’ll work with the maker to keep the claim moving.
Common Chimney Repair Problems We See in Glenn Heights Homes
- Blackland clay movement racking the chimney. Expansive clay soils swell after rain and shrink in drought, and that slow movement racks chimneys built on the same footing as the house. We see cracked crowns, stair-step mortar cracks, and flashing pulled away from the roofline on chimneys that have never been worked on.
- Freeze-thaw spalling at the crown and cap. Water gets into hairline cracks, refreezes on a cold January night, and expands. Brick faces pop off, mortar crumbs fall to the roof, and the crown stops shedding water. It looks like weathering. It’s a repair clock running.
- Deferred liner work. A hairline crack in a flue liner isn’t urgent on a chimney that burns twice a year, but it doesn’t stay hairline forever. We flag liner cracks in our photo report, mark them on the invoice, and let you decide with real information in front of you.
- Flashing pulled off the roofline. On a house off Bear Creek Road, our tech pulled a Level 2 inspection after the owner noticed a rusty stain on the smoke chamber wall. The camera showed the flashing had lifted and water was tracking down the flue liner. We reset and sealed the flashing, poured a new crowned top, and fitted a Copperfield cap. No fire ever touched that chimney. The clay underneath had done all the damage.

FAQs About Chimney Repair in Glenn Heights
Yes, and the reason is the ground, not the fire. Glenn Heights sits on Blackland Prairie clay that swells and shrinks with every wet-dry season, and that movement racks your chimney even if you’ve never lit a single log. A Level 1 camera inspection runs $199, takes about an hour, and shows you exactly what the clay is doing to your crown, flashing, and liner. The inspection fee is credited toward any repair we perform. Call (830) 251-4560 to book.
A Level 1 inspection is a visual and camera check of the flue and exterior; it’s the yearly checkup. A Level 2 adds attics, basements, and crawlspaces, and it’s required after a chimney fire, a real estate transfer, or any change to the appliance. A Level 3 involves opening walls or removing masonry to access hidden areas. In Glenn Heights, most homes we see need a Level 2 only after a water-stain discovery or before a sale.
First-degree creosote is a loose, flaky soot; it brushes off. Second-degree is tar-like and flaky, and it takes more than a brush. Third-degree is a hard, glossy, baked-on coating that forms after high-temperature fires and can’t be swept out; it requires chemical treatment or mechanical removal. We classify creosote in our photo report so the recommendation is matched to what’s actually in the flue, not a generic sweep price.
You’ll get a written price before any tool leaves the truck. Every Flint Chimney Sweep job in Glenn Heights starts with a written quote, line by line, signed and dated. That’s the Garrison Standard, and it’s non-negotiable. If the repair changes mid-job because we find something new, we stop, show you the camera footage, and get your approval before touching it. No surprise invoices, ever. Call (830) 251-4560 and we’ll walk you through the process.
A hairline crown crack in Glenn Heights can usually wait a season or two, especially if you’re not burning and it hasn’t rained hard. A crack that’s opened past a quarter inch, or one that’s letting water run down the flue or the exterior brick, is urgent because freeze-thaw will widen it every winter. We’ll tell you which one you have, show you the camera footage, and quote you a repair price. If it can safely wait, we’ll say so. If it’s urgent, we’ll say that too. The call is free: (830) 251-4560.
