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.

Why Flint Chimney Sweep Is Duncanville’s Preferred Chimney Repair Company
Flint Chimney Sweep has been operating since 2002 as part of the Garrison Partners family of independently owned chimney service companies, led in Duncanville by Hank Delano. Every repair carries the 365-Day Done Right Promise, a written guarantee valid for a full year from the service date. If a covered repair fails within that year, we return at no charge. That’s the Garrison Standard, and it applies to every job we book in Duncanville, no exceptions.
Homeowners in Duncanville call us because the number on the invoice is the number they approved before work began. Our technicians are background-checked and uniformed, so you know exactly who’s walking through the door. We use professional-grade chimney materials, including HeatShield, Gelco, and Olympia Chimney, specified by what the job actually requires rather than what boosts a margin. If you’ve been burned by a chimney company that moved the price at the door or left a mess behind, our process is built to be the opposite of that.
Chimney Masonry Repair in Duncanville
Chimney Masonry Repair in Duncanville means restoring the brick, mortar, and crown on chimneys that have spent decades in North Texas weather. A typical masonry repair here runs $350 – $1,900, depending on how much brick needs to be replaced and how far the mortar joint erosion has spread. On Duncanville’s 1960s and 1970s ranch homes, the original clay-tile flue liners and brickwork have usually shifted with the expansive clay soil under Dallas County, so we match the mortar and replacement brick to the existing structure rather than slapping on a modern prefab system that would look out of place.
Mortar Repointing and Tuckpointing
When mortar joints erode, water gets behind the brick, freezes, and pops the face off the masonry. Repointing means cutting out the failing mortar and packing in fresh material that matches the original, while tuckpointing refines the joints for both strength and appearance. Homeowners near the older sections of Duncanville along Center Street often call once they see white efflorescence staining on the chimney exterior, which is the first sign that water is traveling through the masonry.
Spalling Brick and Crown Rebuilds
Spalling happens when brick absorbs water and the surface flakes or pops off, usually on the weather-exposed side of the chimney. On a job off Greenbriar Lane in north Duncanville, our tech found spalling brick at the chimney crown and a rusted damper that wouldn’t seal, so we rebuilt the crown, installed a stainless cap, and swapped the damper. The homeowner got a photo report showing the before-and-after of the firebox and smoke chamber, and the whole job was booked at a flat price agreed before we arrived.
Chimney Cap Installation in Duncanville
Chimney Cap Installation in Duncanville keeps rain, birds, squirrels, and leaves out of the flue, and it’s one of the most preventable repairs we handle. A standard stainless or copper chimney cap installed on a Duncanville home runs $245 – $650, including setup and the cap itself. Many of the chimneys we see in the city’s older ranch homes either never had a cap or still have one that’s undersized for the flue opening, which lets North Texas downpours pour straight into the smoke chamber and accelerate creosote buildup.
Stainless Steel Caps
We install stainless steel caps from trusted chimney trade brands like Olympia Chimney and Famco. Stainless holds up better than painted steel in Duncanville’s humid springs and sudden freezes, and it won’t rust through the way the original caps from the 1970s did.
Custom Cap Fittings
Older Duncanville chimneys often have odd flue dimensions or multi-flue configurations that standard caps don’t fit. We measure, order the correct cap, and return to install it, and the price includes the fitting visit. A properly fitted cap is the difference between a routine sweep and a liner replacement five years later.
Trusted Brands We Service in Duncanville
We work with professional-grade chimney products including HeatShield, Gelco, Olympia Chimney, and Famco, and we specify them by job, not by margin. When a Duncanville homeowner needs a flue resurfacing rather than a full rebuild, we quote HeatShield because it seals cracks and fills gaps in clay-tile liners without tearing out the chimney. Gelco waterproofing products and Olympia Chimney caps round out the materials we stock for fast turnaround on Duncanville jobs. If you want to verify the materials independently, those brand names are all publicly researchable.
Common Chimney Repair Problems We See in Duncanville Homes
- Cracked clay-tile flue liners: Original clay-tile liners in Duncanville’s 1960s – 70s ranch homes crack from decades of freeze-thaw cycles and shifting clay soil, letting heat and carbon monoxide reach the framing. We identify this with a camera inspection, not a guess.
- Spalling brick and mortar joint erosion: Brick chimneys on older Duncanville homes often show spalling and mortar erosion on the weather side, which lets water into the smoke chamber and rusts the damper. If you see brick flakes on the ground near your chimney, that’s the sign to call.
- Missing or undersized chimney caps: Rain and animals entering an uncapped flue accelerate creosote buildup and turn what should have been a first-degree sweep into a liner repair. A $245 cap often prevents a $2,000 relining.
- Rusted dampers: A damper that won’t seal lets heated air escape in winter and lets cold air fall into the firebox in summer. Duncanville’s humid climate speeds up that rusting, especially in chimneys with uncapped flues.

FAQs About Chimney Repair in Duncanville
Every year if you burn wood regularly, and at least once every two years if you only use the fireplace occasionally. Duncanville’s freeze-thaw winters and humid springs put stress on the brick and crown, so an annual visual inspection catches spalling and mortar erosion before they become a $1,500 repair. Call (830) 251-4560 and we’ll schedule an inspection at a flat price.
First-degree creosote is a light, flaky soot that a routine sweep removes easily. Third-degree creosote is a hardened, glazed tar coating that can fuel a chimney fire and requires rotary sweeping or chemical treatment to remove. In another home near Cedar Ridge, a Level 2 inspection with camera revealed second-degree creosote on the flue liner walls, which our crew removed by rotary sweeping and followed with a HeatShield resurfacing quote rather than an immediate rebuild. The camera tells us exactly what degree you’re dealing with, so you pay for what’s actually there.
Yes. We run a camera through the flue on every repair inspection and send you a photo report showing what we found, what we fixed, and what can safely wait. Nothing gets recommended without camera evidence you can see for yourself. If a crew ever recommends a liner replacement or rebuild without showing you photos, that’s a red flag.
We give you a written price before any work begins, always. For most common repairs like cap installation, crown rebuilds, and standard repointing, we can usually quote a firm price over the phone once you describe the visible damage. For anything involving the flue interior, we’ll book a camera inspection first, then hand you a written price before a single tool comes off the truck. Call (830) 251-4560 for a free estimate.
Hairline cracks in the crown under an eighth of an inch wide can usually wait until the next dry stretch, especially if you’re not burning regularly. But spalling brick on the weather side, a missing cap, or a damper that won’t seal should be addressed before the next North Texas rain season, because water intrusion turns a $500 repair into a $2,000 rebuild. If we tell you it can wait, we’ll tell you exactly why, and what to watch for. Call (830) 251-4560 and we’ll give you a straight answer either way.
