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 Windcrest
Most chimney repair calls in Windcrest start at the top of the stack, not the firebox. The ranch homes here, mostly built in the 1960s and 70s on slab foundations, share a common weakness: original masonry crowns and step flashing that Bexar County’s alkaline clay soil and freeze-thaw swings slowly tear apart. That means cracked crowns, pulled-away flashing, and spalling brick long before the firebox itself gives out. Flint Chimney Sweep handles all of it. We’re part of the Garrison Partners family, founded in 2002, and we serve Windcrest with background-checked, uniformed technicians who put a written price in your hand before any work starts. Call (830) 251-4560 to schedule an inspection or get a free repair estimate.
Why Flint Chimney Sweep Is Windcrest’s Preferred Chimney Repair Company
Windcrest homeowners tell us the same thing again and again: another chimney company quoted a low number over the phone, then doubled it at the door. We don’t work that way. Every job under The Garrison Standard gets a written price before a single tool comes off the truck. The number on the invoice is the number you approved. That’s non-negotiable.
Our Windcrest customers also know the 365-Day Done Right Promise by name. Every repair carries a written guarantee valid for one full year from the service date. If a covered repair fails within that year, we return at no charge. No argument, no requote, no fine print. That’s the difference between hiring a chimney company and hiring one that stands behind the work in writing.
Dispatch for Windcrest runs out of our San Antonio office, and our techs know the streets here: Crestway Drive, Midcrown Drive, and the neighborhoods off West Avenue near the high school. When you call, a live person answers, 24 hours a day, seven days a week. No voicemail tree, no callback form. You’ll speak to a person who can book the visit.
Chimney Liner Installation in Windcrest
Chimney Liner Installation in Windcrest means replacing the inner liner that channels smoke and combustion gases safely out of the house. In Windcrest’s 1960s and 70s ranch homes, the original clay tile liners are now 50 to 60 years old. Hairline cracks from decades of heating and cooling cycles let heat and moisture reach the brick and framing around the flue. A cracked liner is the single most common reason we recommend a repair that cannot safely wait. In Windcrest, a stainless steel liner installation typically runs $2,800 to $4,600, depending on flue height and whether the old liner has to be broken out first. For a resurfacing system like HeatShield, expect $1,800 to $3,200.
When a Windcrest Homeowner Needs a New Liner
You need liner work when a Level 2 camera inspection shows cracks, gaps between tile sections, or missing mortar joints inside the flue. In Windcrest, we also see liner damage from the top down: a cracked crown lets rain sit on the clay tile, and the freeze-thaw cycle splits it. If you see white staining on the exterior brick near the top of the chimney, that’s a sign moisture has been working its way down for a while.
How the Installation Works
For most Windcrest ranch homes, we install a DuraFlex stainless steel liner through the existing flue opening, no tear-out required. The firebox stays intact. We insulate around the liner, seal the top with a proper crown and cap, and hand you a photo report showing the finished install from inside the flue. The whole job usually takes one day for a single-story home.
Chimney Flashing Repair in Windcrest
Chimney Flashing Repair in Windcrest addresses the metal barrier where the chimney meets the roofline. On the original 1960s and 70s roof decks common here, step flashing was often nailed directly to the chimney brick and then roofed over. Decades of thermal expansion and contraction pull those nails loose, and the flashing lifts away from the mortar line. Water gets behind it and travels down the side of the chimney, often showing up as a ceiling stain far from the chimney itself. In Windcrest, flashing repair typically runs $450 to $1,100, depending on how much of the flashing has to be pulled and whether the surrounding shingles are reusable.
Signs Your Flashing Is Failing
Look for a water stain on the ceiling near the fireplace, or on the wall directly above the firebox. Peeling paint on the chimney chase, damp drywall in the attic near the flue, and visible gaps or lifted metal at the roofline are all flashing failures. Windcrest homeowners often misdiagnose this as a roof leak first, which is why we always run a camera inspection before recommending any roof work.
What We Actually Do
We remove the old flashing, clean the mortar joints, and install new step flashing with counter-flashing cut into the brick, sealed with a professional-grade sealant. On Windcrest homes where the original flashing was surface-mounted, we often recommend cutting a reglet line into the mortar for the counter-flashing, which stops the same leak from coming back. Every flashing repair carries the same one-year written guarantee as any other repair we do.
Trusted Brands We Service in Windcrest
We install and work with professional-grade chimney products from manufacturers that Windcrest homeowners can verify independently: DuraFlex stainless steel liners, HeatShield resurfacing systems, and Olympia Chimney caps and chase covers. For crown repair and waterproofing, we use Gelco sealants and Famco flashing components. When our Windcrest customers need parts, we don’t special-order from a catalog and hope for the best. Our San Antonio-based inventory keeps the common sizes for ranch-home flues in stock, which shortens turnaround for most Windcrest repairs to under a week. We also service the full Chimney Repair scope, from crown rebuilds to full chimney rebuilding.
Common Chimney Repair Problems We See in Windcrest Homes
- Cracked chimney crowns on original 1960s-70s masonry. Wind-driven rain off the low-pitch ranch rooflines gets into hairline crown cracks, freezes overnight, and widens them season by season until the crown sheds mortar. Most crowns in Windcrest of this age have never been properly sealed.
- Step flashing pulled away from the roof deck. The original nails corrode and the flashing lifts at the mortar line. The leak shows up as a ceiling stain far from the chimney, which is why we tell every homeowner with a mystery stain to check the chimney before calling a roofer.
- Damper rusted shut from moisture migrating down a degraded liner. The damper plate corrodes against its frame and either jams open, losing heat and killing draft, or jams closed, which the homeowner only discovers when they try to light the first fire of the season.
- Spalling brick at the top of the stack. Bexar County’s alkaline clay soil retains moisture against the brick, and freeze-thaw cycles pop the brick face off in sheets. Spalled brick is a structural issue as much as a cosmetic one: the more face is gone, the more water enters the masonry.

FAQs About Chimney Repair in Windcrest
Not necessarily, and we’ll tell you straight if you don’t. Your neighbor’s crown may have been cracked from a specific freeze-thaw event or years of neglect, while yours might be intact. The only way to know for sure is a Level 2 camera inspection. If your crown is sound, we’ll say so and hand you the photo evidence. No one from Flint Chimney Sweep will recommend a crown rebuild you don’t need. Call (830) 251-4560 and we’ll inspect it, show you the photos, and give you a written recommendation either way.
For Windcrest’s climate, the honest answer is: an annual Level 1 inspection is reasonable, but a full Level 2 camera inspection every year is usually more than most light-burning households need. What matters more than frequency is that the inspection actually checks the top of the chimney, the flashing, and the liner. Windcrest’s freeze-thaw cycles and alkaline clay do more damage to crowns and flashing than a few fires do to the flue. If you burn only a few times a season, get a Level 1 visual inspection annually and a Level 2 camera inspection every three to five years. If you’ve had water stains, damper problems, or bought the house without knowing the chimney’s history, get the Level 2 now.
First-degree creosote is a light, dusty soot that brushes off easily during a standard sweep. Second-degree is a flaky, crunchy buildup that needs more aggressive mechanical removal. Third-degree creosote is a thick, tar-like glaze that hardens against the flue wall. Third-degree creosote is highly combustible and often signals that a liner is already cracked or improperly sized, because the flue was burning too cool. In Windcrest homes with original clay liners, third-degree creosote is a red flag that the liner has failed and may need replacement rather than just cleaning. We’ll show you the camera footage so you can see exactly what we’re seeing.
If water is actively entering the house, it cannot wait. A ceiling stain, damp drywall, or peeling paint near the chimney means water is already inside the structure, and every freeze-thaw cycle through the winter makes the gap wider. If you’re seeing only a small gap in the flashing with no interior evidence of water, it can usually wait a few weeks. But Windcrest’s winter temperature swings are hard on an open flashing seam, so don’t push it to spring if January brings rain. The safe move is to call (830) 251-4560, send us photos or have us run a quick inspection, and we’ll tell you honestly whether it can wait. The estimate is free.
Yes. In nearly every Windcrest ranch home we’ve worked on, the existing firebox is structurally sound and the masonry can accept a new insulated stainless steel liner run straight down the existing flue. We don’t tear out the firebox for a standard liner installation. The old damaged liner is either broken out from the top or left in place and resurfaced with HeatShield, depending on condition and flue shape. Your masonry firebox, hearth, and mantel stay exactly as they are. You get the repair photos before and after, and the liner carries the same one-year written guarantee as everything else we do.
