Fast, Reliable Chimney Inspection Across Kirby
A Kirby Chimney Sweep inspection typically costs $129 – $289, depending on the level of inspection and whether camera work is included. Most inspections on Kirby’s mid-century ranches take 45 – 90 minutes on site, and we walk you through every finding with photo or video evidence before any repair is discussed. If you live in Kirby and haven’t had your flue looked at in years, call (903) 515-5079 and we’ll schedule a time that works.
Kirby’s housing stock has a specific problem most national chimney chains don’t understand. The homes here were mostly built between the 1950s and 1970s, and many still have their original brick chimneys with clay tile liners that are now sixty to seventy years old. Those liners crack. The mortar joints between tiles fail. And because Kirby sits in a climate where chimneys sit dormant through long, humid summers, creosote left over from winter fires hardens and absorbs moisture, turning mildly corrosive. By the time October rolls around and you light that first fire of the season, the flue may be in worse shape than it looks from the living room.
We serve Kirby directly, and our Chimney Inspection in Kirby team knows these older chimneys better than any franchise crew that rotates through town. When you call, you get a live person, not a voicemail queue.
Why Alcott Chimney San Antonio Is Kirby’s Preferred Chimney Inspection Company
Ruben Castellano built Alcott Chimney San Antonio in 2002, and from the first year, the company has treated chimney inspection as an evidence-based practice, not a sales call. That philosophy matters more in Kirby than almost anywhere else in the metro area. Older unlined flues and cracked clay tiles are exactly where the industry’s worst upselling happens because homeowners cannot see inside their own chimneys. We fix that by putting a camera in the flue and showing you the live feed. You see what we see.
Every Alcott technician serving Kirby is background-checked and identity-verified under the Threshold Standard. Before anyone arrives at your door, you get the technician’s name and photo. At the door, they show a photo ID badge. No exceptions. That matters in Kirby, where tight-knit neighborhoods off Old Seguin Road and the subdivisions near Gibbs Sprawl Road deserve to know exactly who is walking up the driveway.
Our Chimney Inspection work in Kirby comes with a written price before any inspection begins and a written guarantee on any repair that follows. If the repair fails within 365 days, the second visit is free. That’s the Done Right Promise, and it applies to every job we do in Kirby, including inspections on homes near Kirby Middle School and the ranch houses along FM 78.

Chimney Camera Inspection in Kirby
A Chimney Camera Inspection in Kirby is the single most useful thing you can buy for an older home with an original chimney. We run a high-resolution camera up the flue while you watch the monitor. You see the cracked tile, the gaps in the mortar, the creosote glaze, the spalling brick. If there’s nothing wrong, you see that too. Cost for camera inspection in Kirby runs $189 – $289, and that includes the photo report you keep. No repair recommendation is made without camera evidence you have watched with your own eyes.
When an Older Flue Hides Damage
Clay tile liners fail from the inside out. The hairline cracks that eventually let smoke into the chase are invisible from the rooftop until they are wide open. Camera work shows the early-stage damage while it is still a repair, not a rebuild. For Kirby homes built before 1980, this is not an optional upgrade. It is the inspection.
Evidence Before Any Reline Recommendation
No Alcott technician in Kirby will recommend a stainless liner or a HeatShield resurfacing without first showing you the camera footage that justifies it. If you are told you need a liner by another company and want a second opinion, our camera report either confirms it or shows you why you don’t. That evidence protects you from the most expensive upsell in the chimney trade.
Fireplace Inspection in Kirby
A Fireplace Inspection in Kirby covers the firebox, damper, smoke chamber, and the visible portions of the chimney from the hearth side. We check for cracked firebrick, a damper that no longer seals, and any sign that smoke has been leaking into places it should not. Most Kirby homeowners schedule this alongside a sweep, and the inspection portion runs $129 – $189 when booked together. If your fireplace has not been used in a few seasons, the inspection is the right first step before you burn anything.
Dampers, Smoke Chambers, and Original Fireboxes
On Kirby’s 1950s and 1960s ranches, the original dampers are often rusted in place or warped from decades of oak fires. The smoke chamber above the firebox is frequently the most overlooked part of the whole system. We check it during every fireplace inspection because a cracked smoke chamber will leak smoke even if the flue liner above it looks clean.
Furnace-Vented Chimneys Need a Different Look
Many Kirby ranches were built with the furnace venting into the same masonry chimney as the fireplace. That changes the inspection. Gas appliance exhaust is cooler and wetter than wood smoke, which means the flue sees different wear patterns. We check for condensation damage and spillage risk specifically when a furnace shares the stack, which is common in homes from the Clearfield subdivision and the older streets around Ackerman Road.
Trusted Brands We Service in Kirby
When a Kirby chimney does need repair, we use the same materials professionals specify: HeatShield for resurfacing damaged clay tile flues, DuraFlex for stainless relining, and Olympia Chimney components for caps and dampers. We do not use box-store substitutes, and we do not improvise. Because we stock these systems locally and serve Kirby several times a week, turnaround on standard repairs is usually a matter of days, not weeks. You get the brand-name material that matches what your chimney actually needs, documented and guaranteed.

AfterCommon Chimney Inspection Problems We See in Kirby Homes
- Heat-damaged mortar behind the brick bulges. That slight outward curve near the roofline on original unlined chimneys is not cosmetic. Decades of oak and mesquite fires have overheated the mortar, and the inner wythe of brick often shows spalling once we get a camera up there. Left alone, this keeps getting worse.
- Cracked clay tile liners with missing mortar joints. Kirby’s mid-century liners fail in predictable ways: vertical cracks along the tile, missing joint mortar, and sections that have shifted out of line. Smoke and heat then get into the chimney chase, which is the start of most chimney fires in older Kirby homes.
- Moisture-damaged crowns and flashing after dormant summers. Kirby’s hot, humid summers let hardened creosote absorb moisture. That moisture then attacks the mortar joints from the inside. Crown cracks and loose flashing let rain in from the top. Both problems compound each other, and both show up on camera before they show up as a leak.
- Appliance vents run through chimneys never designed for them. Many Kirby ranch homes have furnaces or water heaters venting into a masonry chimney built for wood. The flue is oversized for the appliance, the exhaust is cooler, and condensation eats at the clay tile. This is a common finding in homes around Gibbs Sprawl Road and FM 78.

FAQs About Chimney Inspection in Kirby
Kirby’s humidity accelerates flue deterioration because creosote left over from winter fires absorbs moisture during the dormant summer months. Wet creosote becomes mildly acidic, and that acid attacks the mortar joints inside clay tile liners. Homes in drier West Texas do not see this same moisture-driven wear. In Kirby, the damage compounds every summer the chimney sits unused, which is why an annual inspection catches it before it becomes a rebuild. Call (903) 515-5079 to book your inspection before burning season.
Schedule a camera inspection before you burn anything in that fireplace. The bulge is a sign of heat-damaged mortar, and the inner brick is often spalling even if the outside looks intact. We will run the camera, show you exactly what is happening inside the stack, and only then discuss repair options, usually HeatShield resurfacing rather than a full rebuild. Call us and we will give you a written price for the inspection before we come out.
Yes. Oak and mesquite burn hotter than the softwoods many newer fireplaces are designed for, and Kirby’s original chimneys were often unlined or minimally lined. The inspection will document the condition of the flue, the firebox, the damper, and the smoke chamber, so you will know whether your system is safe for hardwoods. If it isn’t, you will see the camera evidence that tells you exactly what needs attention. Call (903) 515-5079 to schedule.
It does. Gas appliance exhaust is cooler and wetter than wood smoke, so the flue sees condensation damage that a wood-only chimney does not. We check for what is called a liner that is oversized for the appliance, which causes that condensation, and we look for spillage where the flue connects to the furnace. Many of Kirby’s older ranches have this venting configuration, and it is one of the things we specifically train our techs to evaluate. Schedule an inspection and we’ll walk you through what we find.
Ask for camera proof. If they recommend a liner, they should be able to show you the cracked clay tile, the missing mortar, the spalling brick on a live feed or in photographs. If they can’t, don’t buy it. At Alcott, no repair recommendation is made without camera evidence you have seen yourself. That is the single biggest protection a Kirby homeowner has, and we have built our entire Chimney Inspection practice around it. Call (903) 515-5079 for a straight answer and a camera to back it up.
