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 Katy
Chimney repair in Katy typically runs $220 – $1,800 depending on what’s actually wrong, and most jobs are done in a single visit. The bigger issue in Katy isn’t usually the flue liner at all – it’s the crown and flashing breaking down from Gulf humidity and the freeze-thaw cycles we get each winter. Flint Chimney Sweep has been repairing chimneys in Katy since 2002 as part of the Garrison Partners family, and every job gets a written price before any work starts. Call Hank Delano’s team at (830) 251-4560 for a straight answer and a free estimate.
We know Katy’s housing stock: Cinco Ranch and Grand Lakes two-story brick veneers, older Nottingham Country homes pushing 25 years, and the newer master-planned sections off FM 1463 where factory-built fireplaces are the norm. Each one fails differently, and a repair crew that doesn’t understand that will sell you work you don’t need. We don’t.
Why Flint Chimney Sweep Is Katy’s Preferred Chimney Repair Company
Homeowners in Katy call us because we show up when we say we will, we put the price in writing before tools come off the truck, and we back every repair with the 365-Day Done Right Promise. That’s a written guarantee valid for one full year from the service date. If a covered repair fails, we return at no charge. No argument, no re-quote, no fine print.
Our technicians are background-checked and uniformed, and a live person answers our phone 24/7 – no voicemail trees or “leave a message and we’ll get back to you.” When you call about chimney work in Katy, you speak to someone who can help. Hank Delano runs Flint Chimney Sweep under The Garrison Standard, the same code every Garrison Partners location follows: documented price, documented scope, written guarantee. That’s not marketing language. That’s how we’ve operated since 2002.
Our crews are dispatched locally from our Houston office, which means we reach Katy neighborhoods like Firethorne, Cross Creek Ranch, and Elyson without the delays some national chains run into. You’ll get a specific arrival window, not “sometime between 8 and 5.”
Chimney Crown Repair in Katy
Chimney Crown Repair is the service we recommend most often in Katy, because the crown – the concrete slab that caps the chimney and sheds water – takes a beating from our weather. Gulf humidity soaks into hairline cracks, then winter temperature swings freeze and expand the water, and the cracks widen. Fast forward a few seasons and mortar is crumbling onto the flashing below, water is seeping into the brick, and the homeowner in Katy sees a ceiling stain and assumes the flue liner leaked. Usually it didn’t.
A proper crown repair in Katy runs $350 – $900 depending on crown size and whether we’re sealing cracks or rebuilding the crown entirely. We use Gelco crown sealer and Olympia Chimney products when the job calls for them, specified by what the chimney actually needs, not by what’s in stock on the truck.
Sealing vs. Rebuilding
Hairline cracks get cleaned out and sealed with a flexible crown compound that handles our humidity and freeze-thaw cycles. A crown that’s actively shedding mortar or has cracks wider than a quarter-inch usually needs to be re-poured. We’ll show you photos either way before you approve anything.
Why the Crown Fails First in Katy
Our climate is rough on concrete. The temperature swings between November and February, combined with the moisture that never really leaves the air here, create exactly the conditions that crack crowns faster than in drier parts of Texas. If your Katy chimney is 15-plus years old and you’ve never had the crown checked, it’s worth a look.
Chimney Repair Companies in Katy
Chimney Repair Companies in Katy come in two flavors: sweeping companies that also fix things, and masonry crews that understand brick but not flue dynamics. Flint Chimney Sweep sits in the middle, and that’s where we want to be. Repairing a chimney correctly means understanding how the crown, flashing, flue liner, damper, and firebox all work together. A masonry-only repair can seal leaks without fixing the draft problem that caused them. A sweep-only company often lacks the skill to re-point mortar or rebuild a crown properly.
What sets us apart in Katy is the process. Before any repair, we run a Level 2 camera inspection when the job warrants it, and you get the photo report. You see what we see. If the work can safely wait, we tell you. If it can’t, you get a written price before we start. No one in Katy should pay for a chimney repair they can’t verify with their own eyes.
What We Repair
Mortar repointing on brick chimneys, spalling brick replacement, chimney waterproofing after crown and flashing work, flashing repair and replacement, full chimney rebuilding when structural integrity is gone, and tuckpointing for older masonry. Each job is diagnosed individually. There’s no package price and no one-size-fits-all pitch.
Inspection Before Repair, Every Time
We won’t repair what we haven’t inspected, and you’ll see the inspection. That’s a promise, not a pitch. It’s how we catch the real problem – like the rusted damper that looked fine from the firebox but was completely seized above it – instead of treating the symptom.
Trusted Brands We Service in Katy
We install and work with professional-grade chimney products because they hold up in Katy’s climate. HeatShield is our go-to for flue liner repair when a liner is cracked but the structure is sound – it’s a cerfied ceramic sealant system that restores the liner without a full rebuild. We also use Gelco crown sealer and Olympia Chimney flashing materials on masonry chimneys, and Copperfield caps when a Katy home needs a new rain cap. These are brands you can look up, verify, and trust. We stock common repair parts for faster turnaround on Katy jobs, and we specify what each job actually needs – nothing gets upsold because it’s what we happen to carry.
Common Chimney Repair Problems We See in Katy Homes
- Cracked crowns and failed flashing from Gulf humidity. This is the number one repair call we get in Katy. Homeowners see water stains and assume the liner is shot. Most of the time it’s the crown or the flashing letting water track down the outside of the flue, not the flue itself. A camera inspection proves which one it is.
- Third-degree creosote glaze in rarely used fireplaces. Katy homeowners burn only a few times each winter, and that casual use creates a different kind of problem. Low-temperature fires leave a hard, glazed creosote that a standard brush can’t remove. It takes chemical treatment or rotary tools to break it down.
- Rusted or jammed dampers in factory-built chimneys. Factory-built metal chimneys are common in Katy’s newer subdivisions, and their dampers rust quickly in our humidity. A damper that won’t seat properly lets conditioned air escape year-round and, more seriously, can allow carbon monoxide to backdraft into the house.
- Spalling brick and crumbling mortar on 20-plus-year-old chimneys. Brick veneer homes from the 1990s and early 2000s in neighborhoods like Nottingham Country and older sections of Cinco Ranch are hitting the age where mortar joints fail. What looks like a cosmetic issue can expose the flue liner to moisture and shorten its life. Tuckpointing and repointing are cheaper now than a rebuild later.

FAQs About Chimney Repair in Katy
Yes, and in Katy the inspection matters more than the sweep itself. Most Katy homeowners burn only a handful of fires each winter, so creosote buildup isn’t the primary risk. The real threats here are crown and flashing failures from Gulf humidity, rusted dampers in factory-built chimneys, and gradual mortar breakdown on older brick chimneys. An annual Level 1 inspection catches those before they become thousands of dollars of repair. If you’re burning regularly, add a sweep. If you’re not, the camera inspection still earns its cost by proving what’s actually happening. Call (830) 251-4560 to schedule.
The only reliable way is a camera inspection, and that’s what we do. A cracked crown usually shows as water stains on the ceiling near the chimney, along with visible mortar grit or small concrete pieces on the roof or in the gutters. Failed flashing tends to drip inside during heavy rain – the tropical downpours we get in Katy make this one easier to spot. A flue liner leak is actually the rarest of the three, and we prove it with a Level 2 camera inspection before recommending any repair. You get the photo report and see the evidence for yourself. We won’t sell a liner replacement on a guess.
Yes. Third-degree creosote is a hard, glazed buildup that forms when fires burn at low temperatures – common in Katy homes that light a fire occasionally during our short winters. A standard brush cannot remove it. We use chemical treatments and rotary cleaning tools designed specifically for glazed creosote, and we’ll show you before-and-after photos. It’s not a quick job, but it’s necessary: third-degree creosote is a chimney fire risk. If you’ve been told your firebox is clean but you still smell tar or see a shiny black coating, call (830) 251-4560 and we’ll take a look.
Mortar repointing and tuckpointing in Katy runs $220 – $650. Crown repair is $350 – $900. Flashing replacement is $180 – $500. Flue liner repairs and partial rebuilds start around $1,200. Every price is set in writing before any work begins, and the number you approve is the number on the invoice. That’s how Flint Chimney Sweep works under The Garrison Standard. We don’t price at the door, and we don’t adjust the quote upward after we start. Estimates are free, so call (830) 251-4560 and get a real number.
Hairline crown cracks can often wait until the next dry stretch in Katy, as long as no water is entering the house. Minor mortar erosion on the exterior can also usually wait a season. But if water is actively staining your ceiling, if you smell smoke inside when the fireplace isn’t in use, if the damper is rusted shut or won’t seat, or if you have third-degree creosote glaze, do not wait. Those conditions carry real carbon monoxide risk and chimney fire potential. If you’re not sure which category you’re in, call (830) 251-4560 and we’ll give you a straight answer – including when the answer is “you can hold off.”
