Fast, Reliable Chimney Inspection Across Highlands
A chimney inspection in Highlands typically runs $199 – $499 depending on the level, and most appointments take under an hour from arrival to written report. We serve the whole 77562 area with crews that know the older brick ranches along North Main, the frame homes near the river, and everything in between. If you’re wondering what’s actually going on inside your flue, call (903) 961-6496 and we’ll get you on the schedule with a real person, not a voicemail loop.
Why Ashby Chimney Houston Is Highlands’s Preferred Chimney Inspection Company
Highlands homeowners call us because we show our work. Nathan Corliss has run Ashby Chimney Sweep since 2002, and the way we inspect chimneys hasn’t changed: we put a camera in the flue, show you the footage on the spot, and hand you a written report before we ever talk about repairs. No guesswork, no “trust me, it’s bad in there.” You see what we see.
Our techs know Highlands chimneys specifically. They understand what the river air does to dampers and what the shifting clay soil under older homes does to clay tile liners. A chimney inspection from someone who’s never worked along the San Jacinto corridor misses what a local crew catches in the first ten minutes. That’s the difference.
Every inspection is done by a background-checked, uniformed technician who arrives in the window we gave you. The price we quote is the price on the invoice. Period. We’re independently owned and operated under the Kingswell Guarantee, which means our word is backed in writing.
We’ve also built our reputation the slow way: answering the phone at all hours, showing up when we say we will, and coming back free if a repair we made fails inside the guarantee period. That’s the 365-Day Done Right Promise, and it applies to every chimney inspection and repair we do in Highlands.

Chimney Camera Inspection in Highlands
A Chimney Camera Inspection in Highlands is the only way to see what’s really happening inside an older flue, and in this town it’s not optional. Highlands sits on expansive clay soil that swells and shrinks with every wet-dry cycle along the San Jacinto River, and that movement hairline-cracks clay tile liners in ways a visual check from the roofline would never catch. We feed a high-resolution camera down the full length of the flue and record it.
What you get: live footage on our screen while we narrate what’s on it, a written report with photos, and a straight answer about whether your chimney is safe to use or needs work. A Level 1 visual inspection just can’t see past the damper into the smoke chamber, and that’s exactly where Highlands chimneys tend to hide their worst problems.
When Highlands Homeowners Need a Camera Inspection
If the home was built before 1990 and the fireplace still has its original clay tiles, schedule a camera inspection before the first fire of the season. If you’ve had water intrusion, musty smells from the firebox, or foundation movement, don’t wait. We also recommend a camera inspection for anyone buying or selling a home in Highlands, because private home inspectors rarely put a camera more than a few feet up the flue.
What a Camera Inspection Covers
We record the entire flue from the firebox to the cap, checking for cracked or misaligned tiles, gaps in mortar joints, creosote glaze, water staining, and signs of animal entry. The footage goes on a report you keep, not just something we glance at and forget. If we spot a problem, you’ll see it with your own eyes before anyone recommends a fix.
Fireplace Inspection in Highlands
A Fireplace Inspection in Highlands means checking everything from the firebox floor to the chimney crown, because a fireplace that looks fine from the living room can be falling apart where you can’t see. Highlands’ humid climate and the constant moisture from the river push dampers toward rust and mortar toward spalling, and the sulfur-heavy air from nearby refineries can leave residues that accelerate wear on masonry and metal components.
We inspect the firebox for cracked refractory panels, the damper for full open-close function and rust-through, the smoke chamber for gaps and glazing, the flue itself, and the exterior crown and flashing for water entry. You get a written summary that separates “safe as-is” from “needs attention,” and if something needs attention, you’ll know exactly why with the footage to back it.
Firebox and Damper Checks
Highlands homes near the river see more damper rust than almost anywhere else in the Houston metro. A seized damper isn’t just annoying; it can force smoke back into the house on startup or let your conditioned air pour up the chimney all summer. We test every damper by hand during a fireplace inspection, no exceptions.
Masonry and Crown Assessment
Older Highlands brick ranches often have original crowns that have been patched a dozen times and still leak. We inspect every crown from the roofline and from below, because water that gets into brickwork above the flue travels down and rots ceiling joists and wall framing. In Highlands specifically, the combination of humid air and regular rain makes crown maintenance the difference between a small repoint and a full rebuild.
Trusted Brands We Service in Highlands
When a Highlands chimney inspection turns up a repair, we use materials we’d put in our own homes. We keep HeatShield resurfacing materials on our trucks for common liner repairs, along with DuraFlex stainless liners for full replacements and Gelco crown sealants for masonry weatherproofing. That means less waiting on parts, which matters when you need your fireplace back before the weather turns. We service and repair systems from every major manufacturer, not just one brand, and we order what we don’t stock directly from the supplier so you’re never paying for a mystery box part.

AfterCommon Chimney Inspection Problems We See in Highlands Homes
- Cracked clay flue tiles from shifting soil. Highlands’ expansive clay expands and contracts dramatically with river-side moisture, and over decades that movement cracks the vertical flue liner. A camera inspection is the only way to document it before it becomes a carbon monoxide risk or a chimney fire.
- Hidden spalling behind the damper. Mortar joints inside the smoke chamber degrade from decades of heat and humidity, and the flakes can drop and block the flue. Visual checks from the firebox can’t see this; a camera can.
- Rust and mildew on dampers and metal fireboxes. The San Jacinto keeps ambient humidity high even in drought years, and that moisture eats metal parts. We regularly find dampers that won’t fully close, which wastes cooling dollars and lets musty river air fill the house.
- Water intrusion through crowns and flashing. Heavy Gulf rains and the periodic river flood events push water through cracked crowns and rusted flashing. The damage is slow and silent until ceiling stains show up, and by then the framing’s already compromised.

FAQs About Chimney Inspection in Highlands
Highlands’ expansive clay soils move more aggressively than the sandy loam under much of Houston, which puts lateral stress on chimney foundations and flues. That’s why we strongly recommend camera verification here even on chimneys that look fine from outside. The movement is slow and seasonal, but over decades it cracks clay tiles and can shift the entire chimney stack.
Yes, and actually the occasional-use chimneys in Highlands are often the most dangerous because creosote builds up during the offseason and the humid river air keeps it sticky and prone to glazing. A short fire once a week can hide third-degree creosote that’s one hot burn away from igniting. Get an inspection, even if you only light the fireplace on holidays.
Third-degree creosote looks like a thick, shiny black glaze that’s hardened onto the flue walls, and it’s common in Highlands because the high humidity keeps creosote from drying out and flaking away like it does in drier climates. Instead, it accumulates and eventually hardens into a fuel-rich coating. It requires mechanical removal or chemical treatment, not a simple brushing.
Yes. A camera inspection after any flooding event shows us whether water got into the flue, whether the mortar joints have softened, whether clay tiles have shifted from saturated ground, and whether any debris or mud got pushed into the smoke chamber. We inspect everything from the firebox to the cap and give you a straight answer: safe to use, needs cleaning, or needs repair before you burn again.
We hand you the camera footage. If we recommend a liner repair, you’ll see the crack or gap on screen. If we recommend a crown rebuild, you’ll see the water staining and missing mortar from the roofline. Nathan Corliss built Ashby on that transparency, and our written guarantee means we don’t profit from work that fails. You never pay for a repair you can’t see with your own eyes.
