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 Emberly Chimney Cleaners Is Duncanville’s Preferred Fireplace Services Company
Duncanville homeowners don’t call us because they collect chimney companies. They call because a 1970s ranch on the west side of Cockrell Hill Road has a chimney pulling away from the brick veneer, and someone finally noticed the gap. Our techs have walked dozens of those properties, and we know what to look for before we even set the ladder: cracked crown mortar, flashing that separated during a dry summer, and a flue liner that hasn’t been touched since Nixon was in office.
We operate under the Haven Standard, which means Clause 1 requires a written price, written scope, and written warranty before we start. Clause 4 requires a documented photo record on every job. You get the photos. You see what we see. That’s been our practice since 2009, and it’s why Duncanville customers keep our number in their phone. Our Fireplace Services team arrives in uniform, background-checked, with a named tech and a text when we’re on the way.
Our Fireplace Services in Duncanville
Here’s what we actually do, and how it applies to Duncanville homes specifically.
Wood Burning Fireplace Service
The 1960s-1980s brick ranch homes across Duncanville were built when a fireplace was a feature, not a heating system. Most still have their original clay tile liners, and many have never been professionally swept. We clean the flue, inspect the smoke chamber, and check the damper operation. On a recent 1970s ranch near Cockrell Hill Road, our tech found the chimney had separated ¾ inch from the brick veneer, leaving the flashing wide open. Rain had been funneling into the attic for months. We cleaned the flue, replaced the flashing, and repaired the crown before the owner ever saw a stain on the ceiling. That’s the difference between a sweep and an actual inspection.
Gas Fireplace Service
Gas logs and inserts in Duncanville are common retrofit jobs, usually installed in a firebox originally built for wood. The problem we see constantly: the old clay tile liner behind the gas unit is spalling, sending debris down onto the burner. It looks like rust flakes or gray grit. We service the gas valve, clean the burner assembly, check the venting, and inspect the existing flue condition before an insert goes in. Skip that flue check and you’re paying for a new burner next season.
Fireplace Insert Service
Inserts change the game, especially for Duncanville homes where the original fireplace was never efficient. We install and service wood and gas inserts, using materials sourced from Copperfield and DuraFlex through our buying network. The key point for older Duncanville chimneys: the insert is only as safe as the liner behind it. We measure, we camera-scan, and we quote the liner replacement in writing before any insert work happens. No surprises after the old unit is already out.
Damper Repair
A cast-iron damper rusted shut is one of the most common findings in Duncanville homes. Why? Decades of attic leaks through a cracked chimney crown dripped water down onto the damper plate. Now it won’t open, smoke rolls back into the living room, and the owner thinks the fireplace is broken. Sometimes we can free it and lubricate the mechanism. Usually, on a 45-year-old damper in a Duncanville ranch, we’re replacing it with a top-sealing damper that actually stops the draft when the fire’s out. We’ll show you the rusted parts in the photo report. Written price first, always.
BeforeAfterTrusted Brands We Service in Duncanville
We service and install equipment from Famco, Copperfield, and DuraFlex, among others. Because our buying network moves these materials through volume, Duncanville customers pay honest prices for liners, dampers, and caps. If you’ve got a gas log set that’s been acting up, or a damper plate rattling on a windy night, we can usually identify the brand and stock the replacement part on the truck. That means one trip, not three. And one written quote.
Common Fireplace Problems We See in Duncanville Homes
- Flashing separation from clay soil movement. The Blackland Prairie clay under Duncanville shrinks in summer drought and swells after heavy rain. Your chimney doesn’t move evenly with the house. That shearing force opens flashing gaps, sometimes ¾ inch wide, that let rainwater into attic framing silently for months before a ceiling stain appears. Every one of our fireplace jobs includes a flashing check.
- Cracked crowns from freeze-thaw cycles. North Texas winters are short, but a hard freeze followed by a 65-degree afternoon cracks chimney crown mortar fast. By fall, Duncanville crowns are often crumbling. Water gets in, wears down the mortar joints, and starts spalling the firebox brick below. Crown repair runs $450-$900 depending on size and condition, and it’s the cheapest structural fix you’ll ever do on that chimney.
- Third-degree creosote from short burn seasons. Duncanville homeowners fire up the fireplace during ice storms, burn for a week, then let it sit for eleven months. That pattern glazes first-degree creosote into third-degree tar that a brush can’t remove. It’s a fire hazard and it requires chemical treatment or mechanical removal. If your fireplace only gets used when it’s below freezing, this applies to you.
- Rusted dampers from attic leaks through cracked crowns. A cracked crown lets attic rain drip directly onto the damper plate. The cast iron rusts. The damper seizes shut. Now smoke can’t vent properly. This is a $350-$700 repair, and it’s almost always linked to a crown leak that’s been ignored for years.

FAQs - Fireplace Services in Duncanville
Why do so many Duncanville chimneys need flashing repair during a routine cleaning?
Because the Blackland clay under Duncanville expands and contracts seasonally, which causes brick chimneys to shift and separate from the exterior wall. That separation opens the flashing. Most flashing failures in Duncanville are not from age - they’re from soil movement. We find gaps of ¼ to ¾ inch on homes from the 1960s through 1980s, especially west of Cockrell Hill Road. The repair is straightforward: new flashing, proper sealant, and a crown check to rule out water entry from the top. Call (980) 580-8641 and we’ll put the camera on it.
How often should a wood-burning fireplace in Duncanville be cleaned if it’s only used a few times a year?
Annually, even if you only burn during a couple of ice storms. It sounds excessive, but here’s the issue: short, infrequent burn seasons create exactly the conditions for creosote to glaze over into third-degree tar. That tar is a fire hazard and a brush can’t remove it. Duncanville’s freeze-thaw cycles also crack crown mortar year-round, so the annual visit catches water damage before it becomes a $2,000 repair. A yearly cleaning with inspection is $189-$325, and you get photos proving what we found. Estimate is free.
Can you repair a firebox that has cracked brick from the foundation shifting?
Yes. Firebox brick cracking in Duncanville is usually caused by chimney movement from clay soil heave. We remove the damaged brick, re-mortar the firebox using refractory mortar, and address the underlying cause - which is usually flashing separation or a failing crown that’s letting water weaken the structure. If the firebox damage is structural, we’ll show you the photos and quote the full repair in writing. Don’t ignore cracked firebox brick; it’s a direct pathway for heat to reach combustible framing. Our team can assess it and give you a written number.
What is the most common fireplace problem you find in Duncanville homes built in the 1960s?
A combination of a rusted damper and a cracked crown, usually on original clay tile flues that have never been relined. These homes are 50-60 years old now, and most of them have had zero professional chimney work. The mortar joints in the firebox and smoke chamber are original. The damper plate is rusted. The clay liner is cracked. We clean it, document it with the camera, and give you a written report on what needs work now versus what can wait. You decide. We don’t sell what the photos don’t support.
Do you service gas fireplace inserts in older Duncanville homes that originally had wood-burning fireplaces?
Yes, and this is one of the most common jobs we do across Duncanville. The key is that the existing flue must be checked before an insert goes in. An old clay tile liner that’s spalling will drop debris onto the burner and can create venting problems. We camera-scan the flue, check clearances, service the gas valve, and clean the burner assembly. If the liner needs replacement, we’ll quote it in writing using DuraFlex materials. You’ll see the liner condition in the photo record before you spend a dollar on the insert. Call (980) 580-8641 to schedule.
