Why Ashby Chimney Dallas Is Glenn Heights’s Preferred Chimney Inspection Company
Nathan Corliss has run Ashby Chimney Dallas since 2002, and the approach hasn’t changed: say the price, show up when we say we will, and put the guarantee in writing. Glenn Heights homeowners tell us the same stories about the other guys, the no-show, the price that grew by six hundred dollars at the door, the repair that failed before the next cold snap. That’s exactly why we operate under the Kingswell Guarantee. Every inspection gets a written price before we start, and every repair we recommend during that inspection gets a written guarantee. If a covered repair fails, we come back at no charge. That’s the 365-Day Done Right Promise, and it applies to every job we do in Glenn Heights.
We’re not a call center that subcontracts your chimney to whoever picks up the phone. The technician who arrives at your Glenn Heights home is background-checked, uniformed, and works directly for Ashby Chimney Dallas. When you call our number, a live person answers, 24 hours a day, seven days a week. No callback forms. No “we’ll get back to you on Monday.” That matters when a storm just peeled your chimney cap off and rain is pouring down the flue.
We also understand what Glenn Heights chimneys go through. The clay soils here move more than most people realize, and that movement shows up in chimney masonry long before it shows up in your drywall. More on that below.

Level 2 Chimney Inspection in Glenn Heights
A Level 2 Chimney Inspection is what we recommend for most Glenn Heights homeowners, especially after a hailstorm or high-wind event, before buying or selling a home, or when you’ve had any change to your chimney system. This inspection includes everything in a Level 1 visual check plus a camera scan of the flue interior, inspection of the attic and crawlspace where the chimney passes through, and a close look at the crown, cap, flashing, and the roofline connection. In Glenn Heights, where shifting clay soils cause chimney separation more often than in surrounding cities, the camera portion is the single best way to see what’s actually happening inside the flue liner before it becomes a smoke or carbon monoxide problem. A Level 2 inspection in Glenn Heights runs $349 to $449 for a single fireplace.
When to Upgrade
If your chimney was exposed to hail or heavy wind, if you’re preparing to sell your home in Glenn Heights, or if you’ve noticed a new stain on the ceiling near the fireplace, move straight to a Level 2. A visual-only inspection cannot see the inside of a flue liner or the hidden gap where a chimney has pulled away from the house framing. After the storm seasons we get here, the extra hundred dollars is usually the difference between catching a $400 flashing repair early and paying for a full chimney rebuild later.
Our Camera Setup
We run a high-resolution camera from the top of the flue down to the firebox, and you’ll see the footage for yourself. Nothing gets recommended without visible evidence. If your flue liner is cracked, you’ll see the crack. If it’s clean, you’ll see that too, and we’ll tell you plainly that no repair is needed.
Chimney Leak in Glenn Heights
A Chimney Leak in Glenn Heights almost always traces back to one of three points: a cracked crown, a displaced or missing cap, or failed flashing where the chimney meets the roofline. After one of our North Texas thunderstorms, wind-driven rain finds every weakness in those three points and makes a beeline down the flue or along the chimney chase. By the time you see a brown stain on your living room ceiling, water has often been working its way in for weeks. Leak diagnosis starts at $189 for a targeted inspection, and most flashing or crown repairs in Glenn Heights run between $350 and $850 depending on what we find.
Storm Damage That Shows Up Late
Glenn Heights gets the same hail and wind as the rest of southern Dallas County, but the damage often doesn’t announce itself immediately. A cracked crown from hail impact can sit quietly through a dry month, then let water pour in during the first real rain. A lifted flashing holds through calm weather, then opens just enough during the next strong wind to let water travel along the chimney chase, far from where the damage actually is. That’s why a ceiling stain near the fireplace is rarely a simple fix.
How We Trace It
We start at the top and work down. Crown, cap, flashing, mortar joints, then the flue interior with the camera if needed. In the Willow Creek subdivision after a severe thunderstorm rolled through, we found a displaced chimney cap that had let wind-driven rain pour straight down the flue. The crack in the crown and the failed flashing where the chimney met the roofline matched a ceiling stain in the living room exactly. We sealed the crown, reset the cap, and replaced the flashing before the first freeze risk of the season. That roof leak wasn’t a roof problem at all.
Trusted Brands We Service in Glenn Heights
When a Glenn Heights chimney needs more than an inspection, we stock and install materials from brands we know will hold up to North Texas weather. That means DuraFlex flue liners, HeatShield resurfacing ceramic, and Gelco crown and flashing sealants, along with other trade-specific products we don’t have to experiment with. We keep common sizes and parts on our trucks, so a straightforward repair can often be completed the same day we diagnose it, and we don’t need to strip a part off a different job elsewhere in the metro. When we recommend a repair, you’ll see the product name in writing on your quote along with the labor, and the whole thing is covered by the written guarantee.

AfterCommon Chimney Inspection Problems We See in Glenn Heights Homes
- Cracked crowns from hail impact. The North Texas hail season beats the top of the chimney first. A crown with spider cracking looks fine from the ground, but the next heavy rain seeps into the flue and finds your ceiling.
- Displaced chimney caps after high winds. A cap that’s been lifted or shifted leaves the flue open. We’ve pulled birds’ nests and several feet of wind-blown debris out of flues in Glenn Heights where caps had been knocked askew.
- Flashing failures where the chimney meets the roofline. Storm-driven uplift loosens flashing, and water travels down the chimney chase invisibly for weeks. The stain shows up later, sometimes in a room that isn’t even directly below the chimney opening.
- Chimney separation from the house due to shifting clay soil. Glenn Heights sits on expansive clay that moves with moisture changes. Minor foundation movement often shows up first as a gap between the chimney and the house framing, a problem far more pronounced here than in nearby cities with sandier soils.

FAQs About Chimney Inspection in Glenn Heights
Look at the cap first, from the ground if you can, check whether it’s still sitting level or if it looks shifted. Then check for pieces of mortar or brick on the roof or in the yard near the chimney. Inside, look for new water stains on the ceiling near the fireplace. If you see any of these, call us at (361) 314-3193 and we’ll schedule a Level 2 inspection, the camera will show exactly what the hail did.
Glenn Heights sits on expansive clay soil that swells when wet and shrinks when dry, moving the foundation in small increments that add up over time. That movement often shows up first at the chimney, since a chimney is a separate vertical structure attached to the house at only a few points. We see more cracked flue liners and pulled flashing in Glenn Heights than in cities built on sandier ground, which is exactly why a camera inspection is worth the money here.
Once a year, even if you rarely burn. The main risk in Glenn Heights isn’t creosote buildup from heavy use, it’s water damage and masonry movement from the clay soil and storm seasons. An annual Level 1 or Level 2 inspection catches a cracked crown before it becomes a ceiling stain. If it’s been over a year, call (361) 314-3193 and we’ll get you scheduled.
Yes, and in our experience it’s usually the chimney, not the roof. Water that enters through a cracked crown, a shifted cap, or a failed flashing travels down the chimney structure and shows up on the ceiling below days or weeks later. We’ll trace the path top to bottom, run the camera if needed, and you’ll see the evidence yourself before any repair is recommended.
No. A visual Level 1 inspection catches what’s visible from the outside and from the firebox, but it cannot see the inside of the flue liner, and many older Glenn Heights farmhouse and custom-built chimneys have liner damage that only shows up on camera. If your home was built before modern codes replaced the original clay tile liner, book a Level 2. The camera doesn’t guess, and after the inspection you’ll know exactly what you’re working with. Call (361) 314-3193 to book one.
