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.

Why Flint Chimney Sweep Is Lewisville’s Preferred Chimney Repair Company
Lewisville homeowners call us because we put the scope of work in writing before the first tool comes off the truck. That is not a slogan. It is the Garrison Standard, the same operating code every Garrison Partners location has followed since 2002. Hank Delano leads our crew, and he holds every repair to a simple test: if it is not done right, we return at no charge. The 365-Day Done Right Promise covers every repair we make in Lewisville for a full year from the service date, and a covered failure brings a free second visit.
We know the specific failure patterns in Lewisville homes because we see them week after week. Hail cracks the crown. Freeze splits it wider. Water tracks down the smoke chamber and rusts the damper before anyone notices. Our Chimney Repair team documents what we find with a camera and sends you the photo report, so you decide what needs work based on what you can actually see. No vague assurances. No blind upsell.
Chimney Crown Repair in Lewisville
Chimney Crown Repair in Lewisville is the most common repair we handle, and for good reason. The crown is the concrete slab that caps the top of the chimney and keeps rainwater from running down the flue or into the brickwork. Lewisville sits in the North Texas hail belt, and a single spring storm can crack a crown in a dozen places. The next hard freeze, the kind we get every January in Denton County, splits those cracks wider. Water gets in, and the freeze-thaw cycle starts chewing at the brick and mortar below.
What a Crown Repair Actually Involves
We remove the damaged top layer with cold chisels and a grinder, build a proper crown form with an overhang and drip edge, and pour it so water sheds away from the flue. The cost runs $325 – $650 for a standard residential crown in Lewisville. If the chimney cap is dented or missing, we quote that separately, typically $175 – $400 installed depending on size and material.
How Long a Repaired Crown Lasts
A crown poured correctly and sealed with a professional waterproofing treatment, like Gelco or Olympia Chimney products, typically lasts 15 – 25 years in the Lewisville climate. The crown should extend past the brick on all sides and slope away from the flue opening. Most crowns we repair in Lewisville were originally poured flat or flush, which is why they fail early.
Chimney Repair Companies in Lewisville
Chimney Repair Companies in Lewisville are not all running the same playbook. Some will quote a liner swap over the phone without ever putting eyes on the flue. We do not work that way. When a Lewisville homeowner calls us about a suspected liner problem, we run a camera up the flue and show them the footage. If the liner has third-degree creosote glazing the walls, a brush will not remove it, and replacement may be the honest answer. But if the real problem is a cracked crown letting water behind the liner, we say so and fix the crown first.
What We Quote and What We Do Not
Every repair gets a written price before any work begins. The number on the invoice is the number you approved. We install professional-grade materials from trusted chimney trade brands including Copperfield, Famco, and DuraFlex. We never recommend masonry work without camera evidence you can see for yourself, and we tell you plainly when work can safely wait a season.
What a Repair Visit Looks Like in Lewisville
Our background-checked, uniformed technicians arrive in a marked van, lay down drop cloths, and run the inspection before making any recommendation. You get a written breakdown: what failed, what it costs to fix now, what can wait, and what we would do if it were our house. Then you decide. That is how we handle every Chimney Repair in Lewisville call.
Trusted Brands We Service in Lewisville
We install and work with professional-grade chimney components from Copperfield, Famco, and DuraFlex, and we stock common replacement caps, dampers, and chase covers for faster turnaround on Lewisville jobs. Using a known brand matters because it means the parts are specified for the job, not for our margin. When we quote a DuraFlex liner or a Copperfield cap, you can verify the product independently. We also apply HeatShield and Gelco waterproofing treatments where they are the right call, which in the hail belt is more often than not.
Common Chimney Repair Problems We See in Lewisville Homes
- Hail-cracked crowns that freeze and split. Lewisville gets hit by spring hail on a near-annual basis. The crown takes the direct impact, hairline cracks form, and the next January freeze opens them into channels for water. By the time a homeowner notices staining on the ceiling, the damage usually runs deeper than the crown.
- Flashing that was tabbed over instead of counter-flashed. We see this constantly on re-roofed homes in Flower Mound-adjacent neighborhoods and throughout Lewisville. A roofer tabs the old flashing instead of cutting a proper counter-flash into the mortar joint. The leak shows up in the attic during a hard rain, not at the fireplace, so people look in the wrong place first.
- Third-degree creosote glazing the flue liner. This is the one that separates inspection from guesswork. Third-degree creosote is a hardened, tar-like glaze that a brush cannot remove. We find it with the camera, show you the footage, and make a straight recommendation. Sometimes a liner replacement is the honest answer; sometimes the crown and cap damage is the real problem. You will see the evidence either way.
- Spalling brick on the chimney shoulder. Water gets behind the brick face, and the North Texas freeze-thaw cycle pops the faces off, a condition called spalling. We see it most on chimneys along the older streets near Old Town Lewisville and on two-story homes in The Colony and Coppell. Repointing the mortar and replacing spalled brick stops the structural loss before the chimney needs a full rebuild.
Pricing for Chimney Repair in Lewisville, TX
A chimney crown repair in Lewisville typically runs $325 – $650. Chimney cap replacement runs $175 – $400 installed.

Mortar repointing and tuckpointing runs $40 – $70 per square foot for most Lewisville chimneys.

FAQs About Chimney Repair in Lewisville
Every 12 months. In Lewisville the hail-and-freeze cycle makes annual inspection more important than in milder climates because crown and cap damage develops fast and quietly. One hail season with a cracked crown can let water into the smoke chamber and damper assembly before you ever see a damp spot on the ceiling. After a significant spring hail event, we recommend a crown and cap check even if the calendar says you are not due yet. Call (830) 251-4560 to schedule an inspection with a camera report included.
Yes, in most cases, for a short time, but every freeze-thaw cycle makes the crack worse and extends the water damage deeper into the chimney structure. The risk is not the fire itself; it is what the water does between fires. If you have a cracked crown in Lewisville, the safest course is to have it sealed and waterproofed before the next hard freeze, not after. Our written quote will tell you exactly what needs work and what can wait.
Third-degree creosote is a hardened, glossy, tar-like glaze that forms when creosote deposits are repeatedly heated and baked onto the flue liner. A standard chimney brush cannot remove it, and it is the form of creosote most associated with chimney fires because it burns hot and fast. We identify it with the inspection camera and show you the footage before recommending any liner work, so you are deciding on evidence, not a sales pitch.
Yes, every repair job includes a camera inspection and a photo report showing what failed and what we did about it.

You will see exactly what you paid for and what we left alone. If a covered repair fails within the one-year guarantee period, we return at no charge.
