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 Flower Mound
Chimney repair in Flower Mound typically runs $225 – $2,800 depending on the job, with flashing repairs on the lower end and full crown rebuilds or flue relining on the higher end. Most repairs we handle in Flower Mound are scheduled within 3 – 5 business days, and every job gets a written price before we touch anything. If you’re seeing water stains near your chimney chase, rust on your damper, or spalling brick on the crown, call Hank Delano and the team at (830) 251-4560. We’ll send a background-checked, uniformed technician to your Flower Mound home, run the camera, and show you exactly what’s going on before you spend a dollar.
What you won’t get from us: a vague verbal estimate, a surprise change order at the door, or a recommendation you can’t verify with your own eyes. That’s how we’ve operated since 2002 as part of the Garrison Partners family, and it’s the only way we’ll work in Flower Mound.
Why Flint Chimney Sweep Is Flower Mound’s Preferred Chimney Repair Company
Flower Mound homeowners tend to be skeptical about chimney companies, and for good reason. The industry has too many outfits that quote low over the phone, show up late, and then “discover” thousands in additional work once the ladder comes off the truck. We built Flint Chimney Sweep to run differently, and the difference shows up in how Flower Mound customers talk about us after the job.
Our Chimney Repair team works under The Garrison Standard: a written price before work starts, a written one-year guarantee on every repair, and a free return visit if a covered repair fails. That’s not a sales pitch. It’s the operating code every Garrison Partners location follows, and it applies to every job in Flower Mound, from a simple flashing patch to a full chase rebuild.
We also answer the phone. A live person, 24 hours a day, seven days a week. When a Flower Mound homeowner calls at 7 a.m. on a Saturday because they want to know if a cracked crown can wait until spring, they don’t get a voicemail tree. They get Hank or a member of the team who can talk through what to look for and schedule the visit.
Scheduling is coordinated from our Dallas-Fort Worth office, and our crews serve Flower Mound directly. We know the neighborhoods off Cross Timbers Road, the subdivisions around FM 2499, and the housing stock along Morriss Road. That local familiarity matters when we’re diagnosing crown failures and flashing leaks on 1990s two-story brick homes, which make up a large share of what we see in Flower Mound.
Chimney Flashing Repair in Flower Mound
Chimney flashing repair in Flower Mound usually runs $350 – $900 depending on how much of the existing flashing is salvageable and whether we need to cut and replace the step flashing where the chimney meets the roofline. Flashing is the metal barrier that seals the joint between your chimney and your roof, and in Flower Mound it takes a beating from North Texas hail and the freeze-thaw cycles that hit Denton County every winter. When flashing rusts through or pulls away, water tracks down the chase and into your ceiling, often months after the original storm.
How We Diagnose Flashing Failure
We start with a visual inspection at the roofline, then run a camera down the chase if water staining suggests the leak is traveling. The camera tells us whether the flashing is the only failure point or whether the crown is contributing water entry higher up. Most Flower Mound flashing repairs we complete use Copperfield components for the replacement metal, and we seal the joint with a professional-grade roof cement rated for North Texas temperature swings.
What Flower Mound Homeowners Should Watch For
Staining on the ceiling near the chimney chase. Rust streaks on the interior of the firebox. A damper that’s stiff or rusted shut. These are the classic signs of flashing failure in Flower Mound, and they’re easy to mistake for a roof leak. If you’re seeing any of them, call (830) 251-4560 and we’ll put a technician on it. The estimate is free, and you’ll get a written number before any repair work is approved.
Chimney Crown Repair in Flower Mound
Chimney crown repair in Flower Mound typically costs $450 – $1,400, with full crown rebuilds running higher if the existing mortar has crumbled past the point of patching. The crown is the concrete cap at the top of your chimney that sheds water away from the flue and chase. In Flower Mound, crowns on exterior-chase chimneys are exposed to direct hail impact and repeated freeze-thaw, which causes spalling, cracking, and eventually water intrusion into the chase itself.
When a Crown Can Be Repaired vs. Rebuilt
Small hairline cracks can often be sealed with a professional crown coat. But when the crown is spalling badly, missing chunks, or has a recessed area around the flue where water ponds, Flower Mound homeowners are usually better served by a full rebuild with a properly sloped top and a drip edge that directs water away from the chimney structure. Our Chimney Repair in Flower Mound team will show you the camera footage so you can see the condition yourself before deciding.
Why Flower Mound Crowns Fail Faster Than Expected
The mix of 1980s-to-2000s two-story brick homes across Flower Mound’s north side means many chimney chases sit on exterior walls. That’s different from older, denser Dallas neighborhoods where interior chases are more common and sheltered. An exterior chase in Flower Mound exposes the crown, cap, and flashing to every hail storm and hard freeze that rolls through Denton County. Annual crown and flashing checks are a real local necessity here, not an upsell.
Trusted Brands We Service in Flower Mound
We install and service professional-grade chimney components from DuraFlex, Copperfield, and HeatShield, among others. When a Flower Mound homeowner needs a stainless liner specified for a gas or wood-burning fireplace, we quote DuraFlex. When flashing or caps need replacing, we use Copperfield. When a flue has cracked tiles and the homeowner wants an alternative to a full liner rebuild, HeatShield’s cerfractory sealant system is one of the options we present. The brand is specified by the job, not by margin. We stock common parts for Flower Mound homes and can typically complete most flashing and crown repairs in a single visit.
Common Chimney Repair Problems We See in Flower Mound Homes
- Crown and flashing failures after North Texas hail and freeze-thaw cycles. Water enters the chase, not the flue, and the damage shows up months later as ceiling stains near the chase or a rusted damper. We see this pattern regularly in subdivisions north of Cross Timbers Road.
- Second-degree creosote missed because the sweep only brushes the flue and skips a camera pass. The glazed layer stays behind in the smoke chamber and firebox, and the next burn ignites it. This is why a camera pass is standard on every inspection we do in Flower Mound.
- Cracked flue liner tiles behind a firebox that looks fine at eye level. A Level 2 inspection with a camera is the only way to catch it before carbon monoxide migrates into the home. We find this more often in Flower Mound homes built before 1995 with original clay liners.
- Spalling brick on the chimney face. Water gets into the mortar joints, freezes, and pops the brick face off. Left alone, it’s a structural problem. We address it with tuckpointing, spalling brick repair, and chimney waterproofing where appropriate.
Pricing for Chimney Repair in Flower Mound, TX
Here’s what Flower Mound homeowners can expect. Chimney flashing repair runs $350 – $900. Crown repair runs $450 – $1,400, with full rebuilds above that. Tuckpointing and mortar repointing typically run $600 – $1,800 depending on how many courses of brick are involved. Flue relining, when it’s actually needed, runs $2,200 – $4,500. These are real ranges for this market, not national averages. What moves the number: the amount of brick or flashing that needs replacement, the condition of the existing crown, and whether the damage is confined to one area or spread across the chase.

FAQs About Chimney Repair in Flower Mound
For a wood-burning fireplace used regularly during fall and winter, plan on a sweep and inspection once a year. For gas fireplaces, every two to three years is usually sufficient, but an annual visual check of the exterior crown and flashing is smart in Flower Mound because of the hail and freeze-thaw exposure. If you burn more than a cord of wood a season, or if you burn unseasoned wood, sweep more often. Call (830) 251-4560 and we’ll put you on a schedule that matches how you actually use your fireplace.
A Level 2 inspection adds a camera pass through the full flue, smoke chamber, and firebox, plus a check of accessible exterior chase components. That camera pass is what catches cracked flue tiles, second-degree creosote, and water damage hidden behind the firebox face. We include a photo report so you can see what we see. For Flower Mound homes with exterior chases, we also document crown and flashing condition at the roofline.
If the spalling is minor and there’s no active water intrusion, you may be able to wait a few months. But a spalling crown in Flower Mound gets hammered every time it freezes and thaws, and what looks like a small patch of crumbling concrete in November can be a full crown replacement by March. If you’re not sure, call (830) 251-4560 and we’ll send a technician to look at it. The inspection is part of a free estimate, and we’ll tell you plainly if it can wait.
Yes. We install and service DuraFlex liners, HeatShield cerfractory sealant, Gelco caps and chase covers, and Olympia Chimney components depending on the job spec. The brand is chosen by what the repair actually requires, not by what we make the most margin on. If a Flower Mound homeowner has an existing product from one of those brands, we can inspect it and tell you what’s serviceable versus what needs replacement.
It depends on the repair. Flashing and crown failures are water problems, and water problems get more expensive the longer they’re left, but they don’t usually make the chimney unsafe to burn in the short term. A cracked flue liner is different. If carbon monoxide can migrate into the home, it needs to be addressed before the next fire. The way to know is a Level 2 inspection with a camera, not a guess. Call (830) 251-4560 for an honest assessment and a written price.
We were called to a two-story brick home off Bridlewood Blvd for a Level 2 inspection after the homeowner noticed staining on the ceiling near the chase. Our tech pulled the cap, ran a camera down the flue liner, and found spalling on the chimney crown and rusted-through flashing at the roofline, water tracking down the chase, not a leak from the roof itself. We repaired the flashing with Copperfield components, rebuilt the crown, and the homeowner’s next rain event stayed dry inside. That’s the kind of outcome we work for on every job in Flower Mound.
