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.

Chimney repair in Lavon typically runs $400 – $2,800 depending on the job, and most of what we fix on Lavon chimneys has nothing to do with fire. The Blackland Prairie clay under your foundation expands and contracts through every drought and wet spring, and that movement cracks masonry crowns and pulls flashing loose at the roofline even on chimneys that have never burned a log.

Chimney Flashing Repair in Lavon
Chimney flashing repair is one of the most common jobs we do in Lavon because the flashing is where the chimney meets the roof deck, and Lavon’s weather works against that seal. Hail, high wind, and the slow movement of Blackland clay all pull flashing away from the roofline. Once it separates, water tracks down into the smoke chamber behind the wall, and most homeowners don’t notice until a ceiling stain appears. In Lavon, chimney flashing repair typically runs $350 – $900 depending on how much of the old flashing has to be pulled and whether we’re replacing step flashing, counter flashing, or both.
Signs You Need Flashing Repair
A water stain on the ceiling near the fireplace is the classic tell, but we also look for rusted flashing visible at the roof line and gaps between the metal and the brick. If the flashing is pulling away after a storm, the fix is usually straightforward. If it’s been leaking for a season or more, there’s often secondary damage to the roof deck underneath.
How We Fix It
We remove the old flashing, inspect the roof deck for rot, reset the step and counter flashing with proper overlap, and seal the joint with a quality sealant specified for masonry. Every repair gets a photo report so you can see exactly what was done. The final price is on paper before we touch the chimney.
Chimney Crown Repair in Lavon
Chimney crown repair in Lavon is a job we often pair with flashing work because the crown is the concrete cap at the top of the chimney, and in this soil, it cracks. When the clay beneath a home shifts through wet and dry cycles, the chimney moves with it, and the crown hairline-cracks along the mortar joints. Water gets in, freezes during North Texas cold snaps, and the cracks widen. Spalling brick below the crown follows. A standard crown repair in Lavon runs $600 – $1,500 depending on whether we’re sealing cracks or pulling and recasting the entire crown.
When a Crown Needs Attention
You’ll see hairline cracks running across the top of the chimney, or you’ll notice brick faces popping off below the crown line. That’s spalling, and it means moisture has already worked its way in. If left alone, the damage moves down into the flue and the smoke chamber, and the repair bill climbs with it.
Materials We Use
For crown repair, we work with brands like Gelco and Olympia Chimney because their crown products are formulated to flex slightly with masonry movement. That matters here in Lavon, where the ground itself is the stress vector. A rigid patch on a moving chimney just cracks again next season.
Trusted Brands We Service in Lavon
When we specify materials for a Lavon repair, we name them on the written quote. For flue repairs we often use HeatShield, a cerfractory sealant that restores cracked flue liners without a full tear-out. For crown work we turn to Gelco or Olympia Chimney products. For components like dampers and caps, Famco parts show up on our trucks. We keep common parts stocked in our Dallas-Fort Worth dispatch inventory, so the parts a Lavon homeowner needs are usually on hand the day we schedule the repair, not back-ordered for two weeks.
Common Chimney Repair Problems We See in Lavon Homes
- Crown cracks and spalling brick from soil movement. Lavon sits on expansive clay that shrinks and swells, and that stress shows up as hairline cracks in the crown and brick faces popping loose. Most homeowners assume fire damage. It’s usually the ground, not the fire.
- Flashing pulling away after hail or high wind. North Texas storms are hard on rooflines, and flashing that’s been loosened by wind lets water track down before the attic shows any sign of it. By the time you see a stain, the leak has been running for a while.
- Unused fireplaces with blocked flues. Lakeside homes in Lavon often have fireplaces that haven’t been lit in years. Squirrels, starlings, and raccoons move in. A cracked mortar joint above the smoke chamber goes unnoticed until a carbon monoxide alarm triggers or smoke backs up on the first cold evening.
- Third-degree creosote in fireplaces that do get used. For Lavon homes that burn regularly, the bigger risk is glazed creosote, a hardened tar-like layer that brushes alone will not remove. It’s a fuel source, and the standard removal method is mechanical, not chemical.

FAQs About Chimney Repair in Lavon
Yes. In Lavon, the most common reasons a chimney leaks or fails have nothing to do with fire. The expansive clay soil here cracks crowns and pulls flashing on chimneys that have never burned a log. A camera inspection will show animal nests, cracked mortar joints, a deteriorated flue liner, or a blocked passage before those become a ceiling stain or a carbon monoxide problem. If a chimney has never been used, it’s still been sitting in North Texas weather for years. Call (830) 251-4560 to schedule an inspection.
You don’t, and you shouldn’t have to guess. We run a camera up the flue during every inspection, and the photo report tells you what’s actually there. Creosote buildup gets addressed with a sweep. Cracked crowns, loose flashing, spalling brick, or a damaged liner shows up as repair work, and the photos are yours to keep. That’s the difference between a company selling you a liner you can’t see, and us handing you a picture of exactly what the camera found. Call (830) 251-4560 and we’ll come through with the camera.
Most Lavon chimney repairs land between $350 and $2,800. Flashing work runs $350 – $900. Crown work runs $600 – $1,500. Spalling brick repair runs $800 – $2,000. A full above-roofline rebuild runs $2,200 – $2,800. You’ll get a written, line-item price before any work starts, and the final invoice matches the approved quote. No contingency, no surprise labor charges. Call (830) 251-4560 for an exact quote on your chimney.
Yes, and we will. If the flue liner is intact, the crown has only minor hairline cracks, and the flashing is still sealed, a repair can often wait until the next season, and we’ll write that down for you. But if water is actively entering the chimney, or the flue liner is compromised, or you’re seeing spalling brick, waiting turns a $600 crown repair into a $2,500 rebuild. We’d rather tell you the truth than sell you a repair you didn’t need. Call (830) 251-4560 and we’ll give you a straight answer with photos to back it up.
Third-degree creosote is a hardened, tar-like glaze that forms when a chimney burns hot fires with restricted airflow or partially seasoned wood. It looks like shiny black glass inside the flue, and brushes alone won’t remove it. It’s also a concentrated fuel source for a chimney fire. We remove it mechanically with professional-grade rotary tools and then inspect the liner to confirm no damage was hiding underneath. Your guarantee is in writing, and if it’s not right, we come back. Call (830) 251-4560 and we’ll schedule a camera inspection to see what’s in your flue.
