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.
Fast, Reliable Chimney Repair Across The Colony
Chimney repair in The Colony usually means one of three things: repointing mortar joints that the clay soil has cracked open, rebuilding a crown or flashing that Lake Lewisville wind-driven rain has worked past, or correcting damage inside the flue. Flint Chimney Sweep handles all three, and every job starts with a written price before any work begins. Our crews know the brick chases and exterior masonry chimneys all over The Colony, from Stewart Peninsula to the neighborhoods east of Main Street. Call (830) 251-4560 for a free estimate, and you’ll talk to a live person, not a voicemail tree.
We dispatch background-checked, uniformed technicians to The Colony from our Dallas-Fort Worth office, and every repair carries our 365-Day Done Right Promise in writing: if a covered repair fails within one year, we return at no charge.
Why Flint Chimney Sweep Is The Colony’s Preferred Chimney Repair Company
Hank Delano opened Flint Chimney Sweep in 2002 under the Garrison Partners family, and the standard that guides every job is simple enough to name: The Garrison Standard. Price, scope, and guarantee go in writing before a single tool comes off the truck. The Colony homeowners we work with tend to ask the same two questions after a bad experience with another company: “Is the price going to change once you’re here?” and “What happens if the repair fails?” The answers are no, and a free return visit inside one year. Both are written on the worksheet you approve before we start.
We do not upsell liner replacements because the camera “looks concerning.” We show you the footage. A repair recommendation without photo evidence isn’t a recommendation, it’s a guess. That discipline is why homeowners across The Colony call us back, and why a lot of our work comes from neighbors who watched us work on the chimney two doors down.
Response time to The Colony runs one to three business days for non-emergency repairs. We do not promise same-day service, because a proper chimney repair is booked, scoped, and done with materials specified by the job, not rushed through to hit a dispatch clock. If you have an active leak or visible masonry movement, call (830) 251-4560 and we will get you on the schedule at the first available slot.
Chimney Repair Companies in The Colony
Chimney Repair Companies in The Colony generally split into two groups: sweep-only operations that clean and inspect, and masonry-focused crews that rebuild, repoint, and waterproof. The problem most The Colony homeowners run into is that neither group wants to touch the other’s work, which leaves the homeowner stuck between a clean flue and a leaking chimney. Flint Chimney Sweep handles the full Chimney Repair scope: sweep, inspection, masonry, crown work, flashing, and liner repair. One crew, one written quote, one guarantee.
What the job actually involves
A proper repair in The Colony starts with figuring out where water and exhaust are moving. That means a Chimney Inspection - The Colony with a Level 2 camera scan when we suspect liner or smoke chamber damage, mortar joint probing on exterior brick chases, and a close look at the crown and flashing seams where lake wind pushes rain sideways. After that, we write the scope and the price. You approve it before anything gets torn out.
What it costs
Chimney repair in The Colony most often runs between $300 and $1,800 depending on scope. Mortar repointing on a typical brick chase usually lands in the $400 to $900 range. Crown resealing or flashing repair typically falls between $250 and $650. A full smoke chamber rebuild with HeatShield runs higher, usually $1,200 to $2,800, because it involves parging the walls and sealing the flue path. The number you approve is the number you pay. No door-price changes.
Chimney Masonry Repair in The Colony
Chimney Masonry Repair in The Colony is not optional maintenance; it’s the main line of defense between your chimney and the Blackland Prairie soil under your foundation. The Colony sits on clay that swells with rain and shrinks through dry summers, and that movement racks exterior brick chases against the steel or clay flue inside them. The masonry takes the stress. Hairline mortar cracks spread, flashing pulls loose, and water gets in. The Colony homes with exterior brick chimneys see this pattern years before the firebox shows any wear.
Repointing and tuckpointing
Repointing means cutting out failed mortar joints and packing fresh mortar in. Tuckpointing is the same trade done to match a historic or specific brick finish. On The Colony brick chases, we see joints fail in vertical lines along the chase corners first, where soil movement concentrates stress. Repointing those joints before they open to the weather stops a $400 repair from becoming a $2,500 rebuild.
Spalling brick and waterproofing
Spalling is what happens when water saturates a brick face, freezes or bakes, and the surface pops off in flakes. The Colony’s freeze-thaw cycles are mild compared to the northeast, but lake-side humidity pushed by wind keeps brick damp enough to spall, especially on shaded north-facing chases. We repair spalled faces by cutting out the ruined brick, setting a matched replacement, and applying a breathable waterproofing treatment so moisture never camps inside the masonry again.
Trusted Brands We Service in The Colony
We stock and install parts from Famco, Copperfield, and HeatShield for The Colony customers, and we specify the brand by the job, not by the margin. A rebuilt damper gets a Famco cast-iron or steel plate because their sizing tolerances hold up over repeat open-close cycles. Crown resealing often gets Copperfield sealant, which stretches with the clay-soil movement instead of splitting. Smoke chamber repairs use HeatShield parging, which meets the fire-code standard for resurfacing the chamber above the damper. You can verify any of those materials independently. We’d rather you look them up.
Common Chimney Repair Problems We See in The Colony Homes
- Clay-soil racking cracking mortar joints and flashing gaps. The chase moves against the flue during wet-dry cycles, and the first sign is often a hairline crack at a chase corner that leaks during the next rain. The fireplace may burn fine while the masonry quietly opens up.
- Lake-side wind-driven rain getting past the crown and flashing. On calls off Stewart Peninsula and along the lake edge, we routinely find rusted dampers and decaying smoke chamber mortar from rain forced sideways past failing flashing. The stain line on the flue tells the story.
- Third-degree creosote glazing that a brush cannot remove. Fireplaces run with unseasoned wood or a choked damper build a tar glaze that hardens on the liner. Standard sweeping knocks off first and second-degree creosote. Glaze needs chemical or mechanical treatment, and it is a leading cause of chimney fires.
- Efflorescence on brick faces. White salt staining forms when water moves through the masonry and evaporates, leaving minerals behind. It’s not a structural failure by itself, but it tells you water is traveling through the brick. We treat the moisture path, not just the stain.

FAQs About Chimney Repair in The Colony
Every year if you burn wood, and every other year at minimum if the chimney is decorative or venting gas logs. The Colony’s clay soil shifts exterior chases enough that mortar and flashing movement can develop between seasons, and the only way to catch that early is a camera-and-probe inspection, not a glance from the ground. A visual check is not an inspection. A Level 2 camera inspection is the real thing. Call (830) 251-4560 and we will put you on the schedule.
Yes. First-degree creosote is a fine black soot that brushes off with a standard sweep. Second-degree is flaky and brittle. Third-degree is a hard, shiny tar glaze that bonds to the liner and will not come off with a brush. We identify which one you have during the inspection and show you the camera footage, because a brush sweep on third-degree glaze is wasted money. Glaze removal and liner treatment cost more than a sweep, and we only recommend it when the camera evidence is in front of you. Call (830) 251-4560 to book an inspection with a photo report.
Usually not if the crack is under a quarter-inch wide and not growing, but it should be photographed and checked at your next inspection. What makes it urgent in The Colony is the weather pattern: a hairline crack in the mortar becomes a water path during the first lake-side wind-driven rain, and water trapped behind the brick will spall the face or rust the damper. We would rather tell you it can wait than sell you a repair you do not need, and the way we know the difference is by documenting the joint with photos and checking it over time. Call (830) 251-4560 and we will give you a straight answer.
No. We do not run same-day repair routes because proper chimney work in The Colony requires the right mortar, the right sealant, and the time for materials to set. That said, if you have an active leak or visible masonry movement, call (830) 251-4560 and we will fit you into the earliest available slot. You will get a written scope and price before anything starts, same as every job we run.
The quote covers the full scope: materials, labor, cleanup, and our written 365-Day Done Right Promise. The price is flat and cannot change once you approve it. If we open the chimney and find additional damage, we stop work, document it with photos, and give you a new written price before continuing. The number you approve is the number on the invoice. Call (830) 251-4560 for a free estimate on your The Colony chimney.
