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 Seguin
Chimney repair in Seguin runs between $350 and $4,800 depending on what failed. A crown repair or flashing fix typically lands in the $350 – $900 range, while a full flue relining with HeatShield or a DuraFlex liner runs $2,200 – $4,800. We’re Flint Chimney Sweep, and we’ve worked on chimneys across Seguin long enough to know that the clay soil along the Balcones Escarpment moves more than most people realize. That movement is why we see more cracked crowns and pulled flashing here than in New Braunfels or Cibolo. Call (830) 251-4560 and we’ll give you a written price before anything comes off the truck.
Why Flint Chimney Sweep Is Seguin’s Preferred Chimney Repair Company
Seguin homeowners call us because we put the price in writing first. No one likes a technician who finds “unexpected damage” and doubles the bill at the door. Our process is different: we inspect, we document with a camera, we hand you a written quote, and we don’t touch a brick until you approve it. That’s the Garrison Standard, and it’s the same discipline every Garrison Partners location follows.
We dispatch from our San Antonio office, so response to Seguin is consistent, and our technicians know the housing stock here: 1950s and 1960s ranch homes off Court Street, newer builds near the Seguin High School corridor, and farmhouse-era masonry along Hwy 123. A chimney on a 1962 ranch in the Glen Cove neighborhood fails differently than one on a 2005 build near Vogel Elementary, and we plan repairs accordingly.
Our team is led by Hank Delano. Every technician who walks through your door is background-checked, uniformed, and trained to work the way the Garrison Code requires: clean, documented, and guaranteed in writing for a full year. If a repair fails within 365 days, we come back at no charge. That’s the 365-Day Done Right Promise.
Chimney Liner Installation in Seguin
Chimney liner installation in Seguin means replacing the inner passage that carries smoke and exhaust out of your house. In homes here, especially older ones burning post oak and mesquite, we see third-degree creosote glazing that eats at clay tile liners. When a liner cracks or separates, the chimney can no longer safely vent. A stainless liner from DuraFlex or Olympia Chimney gives the flue a smooth, insulated path again. A HeatShield resurfacing often does the same job at lower cost when the existing liner is still structurally sound. In Seguin, liner work typically runs $2,200 – $4,800, with the written quote spelling out material and scope before we begin.
When a Seguin Home Needs It
You may need a new liner if you see flaking tile pieces in the firebox, if smoke backs up into the room, or if your Level 2 camera inspection shows cracked or missing sections. Homes along County Line Road and the older streets near Park Plaza have clay tile liners that have absorbed decades of moisture from humidity and storms off the Gulf. That clay spalls, then collapses inward. We document everything with photos so you see the damage before you spend a dollar.
What the Job Involves
We remove or resurface the failed liner, install the specified system, and seal the connection at the smoke chamber. We use Copperfield and DuraFlex stainless where the flue serves a wood-burning fireplace or furnace. If you only need surface repair to a sound liner, HeatShield can rebuild the parge coat from inside, which costs less than a full reline. We’ll show you the camera images and let you decide.
Chimney Flashing Repair in Seguin
Chimney flashing repair in Seguin means fixing the metal that seals the joint where the chimney meets your roof. Here along the Balcones fault line, our clay-heavy soil swells and shrinks from drought to deluge, and that shift pulls flashing free from the masonry. Water gets behind the counter-flashing, runs down the smoke chamber, and suddenly you’ve got a wet spot on the ceiling that looks like a roof leak but isn’t. We see this more in Seguin than nearly any other repair. Flashing work here runs $350 – $900 depending on how much of the roof line we have to open.
Signs Flashing Has Failed
Look for water stains on the ceiling near the fireplace, rust streaks on the chimney exterior, or a musty smell in the attic after rain. During the dry spells, caulk cracks and lifts away from the brick. Then the drought breaks, we get a two-inch rain, and water tracks straight into the smoke chamber. Chimney flashing has a lifespan of roughly 15 – 20 years in this climate.
How We Fix It
We pull the old flashing, inspect the step flashing and counter-flashing, and replace what’s corroded. We seal the joint with a professional-grade product, not a caulk tube from the hardware store. The repair is documented with photos, priced in writing, and covered by the 365-Day Done Right Promise.
Trusted Brands We Service in Seguin
We work with DuraFlex stainless liners, HeatShield resurfacing systems, and Copperfield flashing components on jobs across Seguin. We stock common sizes at our San Antonio yard, which means less waiting when your liner measurement calls for a 6-inch or 8-inch flex run. If a Famco cap or top plate fails, we carry replacements that fit the most common local flue tile dimensions. You’ll never be told to wait six weeks for a part because the right one wasn’t ordered. We name the material on every written quote so you can look up the spec yourself.
Common Chimney Repair Problems We See in Seguin Homes
- Cracked crowns from clay-soil movement. The Balcones fault zone means Seguin’s soil expands and contracts more aggressively than flat prairie towns. Crowns crack, water gets in, and the freeze-thaw cycle would make it worse if our winters were longer.
- Lifted flashing from drought-to-deluge swings. When the soil under your foundation shifts, the chimney moves independently of the roofline. Flashing pulls away and water follows.
- Spalling firebox brick from repeated moisture cycling. Brick absorbs water, dries, absorbs again. The face pops off the brick. You’ll see flaking brick and mortar crumbs in the firebox after burning season.
- Third-degree creosote glazing in hardwood-burning homes. Post oak and mesquite produce dense smoke that condenses into a hard, shiny glaze on flue walls. A standard brush won’t remove it. That’s when we recommend chemical treatment or HeatShield.

FAQs About Chimney Repair in Seguin
Once a year. If you burn more than two cords of wood per season, every six months. Seguin’s humidity and clay-soil movement put extra stress on crowns, flashing, and mortar joints, so an annual inspection catches small cracks before they become structural problems. Call (830) 251-4560 to schedule, and we’ll give you a written price for the inspection before we arrive.
The camera shows the inside of your flue liner, the smoke chamber, and the throat area in full color. You’ll see cracked tile, glazed creosote, missing mortar joints, and any separation between liner sections. We send you the photos and walk through them with you on site. Nothing gets recommended without visual proof you can see yourself.
Only if the crack is hairline and not letting water through. Once water enters the smoke chamber, freeze-thaw cycles and ongoing soil movement turn a $500 flashing fix into a $2,400 liner replacement. We were called to a 1950s ranch house off Huber Road where the homeowner smelled smoke in the attic. Our camera inspection found a cracked crown and lifted flashing pulling away from the firebox surround, letting water track down the smoke chamber. We rebuilt the crown, reset the flashing with a new counter-flash, and swapped the failing damper. The repair was $1,600 total. Waiting another season would have meant a full liner job.
Third-degree creosote is a hard, shiny glaze that forms when smoke from dense hardwood like post oak condenses on flue walls. It’s the leading cause of chimney fires in Seguin because it burns at high temperatures once ignited. A standard wire brush can’t remove it. We use chemical treatments or mechanical methods designed for glazed creosote, and we document before and after with the camera. Call (830) 251-4560 for a written quote.
No. We schedule repairs by appointment. Sweeps and inspections can usually be booked within a few days, but proper repair work, especially crown rebuilds and liner installations, requires planning, material ordering, and curing time. We don’t rush a mortar job, and we won’t promise a timeline that sacrifices the quality of the repair. Scheduling is straightforward: call (830) 251-4560 and we’ll give you the next available slot plus a written price for the work.
