Why Flint Chimney Co Dallas Is Duncanville’s Preferred Chimney Inspection Company
Homeowners in Duncanville don’t call us because they want a chimney inspection. They call because they saw a ceiling stain after a spring storm, or heard something in the flue, or got a home inspection report flagging spalling on the clay liner. Our job is to answer the question the last company wouldn’t: what’s actually wrong, what does it cost to fix, and does it need to be done now or can it wait. That answer comes in writing, with a price approved before any tool comes off the truck.
Hank Delano, who leads our inspection work, runs every call under The Garrison Standard: the same code every Garrison Partners location follows. That means one written price, no add-on surprises at the door, and a report with photos from the camera inspection. If we recommend a repair, you see the evidence – spalled flue tile, cracked crown, failed flashing – not a vague warning. The 365-Day Done Right Promise covers every repair in writing for one full year. If a covered repair fails, we return at no charge.
We also answer the phone with a live person, 24 hours a day, seven days a week. No voicemail tree. No “we’ll call you back Monday.” When a Duncanville homeowner calls at 9 p.m. because water is dripping into the firebox, someone picks up.

Level 2 Chimney Inspection in Duncanville
A Level 2 Chimney Inspection in Duncanville is what we recommend for any home that has been through a severe weather season, changed ownership, or gone more than two years without a look inside the flue. It includes everything in a Level 1 visual check, plus a camera scan of the full flue interior, the smoke chamber, and the accessible portions of the exterior crown and flashing. In Duncanville, where hail and wind-driven rain hit hard from March through June, a Level 2 inspection is the standard before the first fire of the season. Cost runs $299 to $549 depending on roof access and flue height.
What the camera scan actually shows
We run a camera the full length of the flue. On Duncanville ranches from the 1960s and 70s, the footage typically reveals one of three things: gaps between clay tile sections from decades of thermal expansion, a missing or displaced cap that let animals in, or a crack in the crown that has been funneling water behind the flashing. You see every frame. No one tells you the liner is shot without showing you the footage first.
When a Level 2 is the right call
If you just bought a home in Duncanville, the real estate inspection may have flagged the chimney as “further evaluation recommended.” That means Level 2. If your home has never had a camera inspection and it was built before 1990, that also means Level 2. And if a storm tore shingles off your roof or you found water in the firebox, a Level 1 visual check is not enough – the damage lives inside the flue, where only a camera sees it.
Chimney Leak in Duncanville
A Chimney Leak in Duncanville rarely starts where you see the water. The ceiling stain in the den, the rust streaks on the firebox wall, the musty smell after a hard rain – those are symptoms. The source is usually higher: a cracked crown, failed flashing at the roofline, or a cap that got knocked loose by hail. We find it with a Level 2 inspection and quote the repair in writing before any work begins. Leak diagnosis with camera inspection runs $299 to $449.
Cracked crowns and displaced caps
Duncanville’s freeze-thaw cycles are hard on chimney crowns. Water seeps into hairline cracks, freezes, expands, and the crack widens. After a few North Texas winters, a crown that looked fine now channels rainwater directly into the flue. On a ranch home near Ten Mile Creek last spring, our tech found a cracked crown and displaced cap after a thunderstorm; water had run behind the flashing and stained the den ceiling. We performed a Level 2 inspection, identified spalling on the clay flue liner, and installed a new Olympia Chimney cap and crown coating before the first fall fire.
Flashing that fails quietly
On 1980s two-story brick veneer homes throughout Duncanville, flashing at the chimney-roof junction was often installed with thin gauge metal and roof cement that breaks down after 30 years of Texas sun. The first sign is usually a brown stain on the ceiling near the fireplace after a hard wind-driven rain. By that point, water has already wicked into the smoke chamber. The fix is new flashing, cut and sealed properly, plus a camera check of what got wet inside. We stock Gelco and Olympia Chimney flashing materials for fast turnaround on Duncanville jobs.
Trusted Brands We Service in Duncanville
We don’t install whatever is cheapest on the truck. Flint Chimney Co Dallas uses professional-grade materials from chimney trade brands that have a documented track record in North Texas conditions. That means HeatShield for flue resurfacing, Olympia Chimney for caps and crowns, and Gelco for flashing and chase covers. When a Duncanville homeowner needs a part, we’re not waiting two weeks for an online order – our Dallas-Fort Worth parts inventory keeps common Duncanville repairs moving on schedule. We also service existing installs from Famco. If a previous company used a brand we don’t stock, we’ll tell you plainly what can be matched and what should be replaced.

AfterCommon Chimney Inspection Problems We See in Duncanville Homes
- Missing or displaced chimney caps in pre-1990 brick veneer homes. Many original Duncanville chimneys were built without a cap at all. The result is chimney swifts nesting in the flue, raccoons in the smoke chamber, and rain pouring straight down the liner. We check for animal guards and bird screens on every inspection in Greenbriar and Ten Mile Creek.
- Cracked chimney crowns from hail and wind-driven rain. Duncanville sits in a hail corridor. Crowns take direct hits, and the cracks that follow let water into the flue where it spalls the clay liner over time. By the time you see a ceiling stain, the liner has usually been degrading for years.
- Failed flashing on 1980s two-story brick veneers. The original flashing on many Duncanville two-story homes was thin, poorly sealed, and never meant to last 40 years. It fails at the roofline corners first, often without visible damage from the ground.
- Clay flue liner spalling from decades of thermal stress. Duncanville’s hot, humid summers followed by sharp winter drops cause constant expansion and contraction in original clay liners. Hairline cracks become spalled sections, and spalled sections become a fire hazard. A camera inspection shows exactly where the liner stands.

FAQs About Chimney Inspection in Duncanville
Check three things: the cap is still in place and not tilted, the crown has no fresh cracks wider than a hairline, and there is no water stain on the ceiling near the fireplace. If any of those shows up, book a Level 2 inspection before your first burn. Storm-driven rain gets behind flashing fast, and the first fire after water intrusion can force moisture into the flue and crack the liner. Call (361) 492-4099 and we’ll get a tech to Duncanville that week.
Yes, if the flue has no cap and you use the fireplace, an annual Level 2 inspection is the safe call in Duncanville. Uncapped flues collect nesting material, water, and debris faster than capped ones, and a camera scan is the only way to see what has accumulated mid-flue. Homes in Greenbriar and Ten Mile Creek with original clay liners are at the highest risk. If the inspection shows you need a cap, the fix is straightforward and we quote it in writing on the spot.
The first sign is almost always a brown ceiling stain near the fireplace after a hard wind-driven rain, not visible damage from the ground. By the time flashing looks rusted or lifted from the street, water has usually been getting in for months. The sure test is a Level 2 inspection with roof access. We inspect the flashing joints, check the crown above them, and run the camera to see what got wet inside. Call (361) 492-4099 if you’ve seen a stain after rain.
Because Duncanville’s older housing stock – especially the mid-century ranches and 1980s brick veneers in neighborhoods like Greenbriar and Ten Mile Creek – was built before cap installation was standard practice. Nearby cities with newer homes built under post-2000 building codes tend to have caps and screens already in place. In Duncanville, an uncapped flue is an open entry point for chimney swifts and raccoons. Our inspections check for animal entry on every call because we see it constantly here.
No. A Level 1 visual check only looks at what is accessible from the firebox and the roof. If the chimney has never been cleaned, you need a Level 2 with camera scan to see the actual condition of the flue interior. Duncanville homes from the 1960s through the 1990s often have original clay liners with hidden spalling, plus creosote buildup that narrows the flue. A Level 1 can miss both. Book the Level 2, get the footage, and then decide what actually needs work. Call (361) 492-4099 for current Duncanville pricing.
