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.
Fast, Reliable Gas Fireplace Repair Across The Colony
A gas fireplace repair in The Colony usually costs $165 – $385 for a service call with component replacement, depending on which part failed and whether it’s a factory-built zero-clearance unit or a direct-vent insert. Most repairs on Heatilator and Majestic units we see in The Colony are diagnosed and fixed in a single visit. Call Alcott Chimney Sweep at (336) 863-3889 and you’ll speak with a live person who can schedule a technician that same week.
If your gas fireplace sits along the Lewisville Lake shoreline or in one of The Colony’s older master-planned subdivisions, you’re dealing with conditions that inland DFW homes simply don’t face. Wind-driven lake moisture gets into prefabricated chases and terminates caps years before they’d fail in Frisco or Carrollton. We know The Colony’s housing stock, we know which factory-built units are reaching the end of their design life, and we name the technician coming to your door before we arrive.
Why Alcott Chimney Sweep Is The Colony’s Preferred Gas Fireplace Repair Company
Our Gas Fireplace Repair team has been working in The Colony long enough to recognize the patterns other companies miss. When we get a call from a homeowner in the Stewart Peninsula or The Tribute area about a fireplace that won’t draft, we already know what we’re likely to find: a termination cap rusted through by lake wind, or refractory panels cracked from 30 years of expansion and contraction.
Every technician we send into The Colony has passed the Threshold Standard: a background check, identity verification, and a uniformed arrival where you already know the name and photo of the person at your door. That’s not an add-on service. It’s how every single visit works, whether we’re doing a Level 2 inspection on a zero-clearance unit in The Cascades or resealing flashing near Ridgepointe.
Ruben Castellano set the standard for Alcott Chimney Sweep from day one in 2002: a written price before any work begins, a written guarantee on every repair, and a free return visit if that repair fails within the coverage period. The Colony homeowners who call us repeatedly do so because they got a straight answer the first time, not because they needed us back to redo work.
Our Gas Fireplace Repair Services in The Colony
Factory-Built Gas Fireplace Component Replacement
The Colony’s housing stock is dominated by factory-built zero-clearance fireplaces, most of them installed between the mid-1970s and the mid-1990s. Heatilator, Majestic, and similar brands have refractory panels, gaskets, and burner assemblies designed to last 20 to 30 years. Many Colony homes are past that mark. We replace degraded refractory panels, failed gaskets, and worn gas valves with manufacturer-specific parts rather than generic substitutes, because a factory-built firebox is only as safe as the components designed for it.

Level 2 Chimney Inspection for Zero-Clearance Systems
A Level 2 inspection covers what you can’t see from the living room: the aluminum flue liner inside the chase, the chase top, the termination cap, and the flashing where the chase meets the roofline. In The Colony, clay-soil movement and lakeside humidity work against all of that simultaneously. We run a camera through the entire flue system and give you a photo report so you can see exactly what we saw. If we recommend a repair, you’ll have the images to verify it yourself.

Chase Cover and Termination Cap Resealing
The lake’s prevailing southeast wind pushes moisture into hairline gaps around chase covers and termination caps, and seasonal clay heave keeps reopening those gaps. A rusted termination cap on a 15-year-old Colony fireplace is not unusual. We replace the cap, reseal the flashing with professional-grade sealants, and in many cases install a properly sized chase cover that keeps water out of the metal flue entirely. This is one of the most common and most preventable repairs we perform in The Colony.

Gas Log Set and Burner Assembly Service
If your gas fireplace lights but the flame is yellow, weak, or uneven, the burner assembly or log set may be clogged with dust, pet hair, or corrosion. The Colony’s higher ambient humidity accelerates oxidation on burner tubes and gas orifices. We clean, adjust, and when necessary replace these components using the same trade-grade parts chimney professionals specify.

Trusted Brands We Service in The Colony
We service and install components from HeatShield, Gelco, Olympia Chimney, and Famco, which means the parts we bring into Colony homes are the ones professionals specify, not box-store substitutes. If you have a Majestic or Heatilator unit from the 1980s or 1990s, we can still source the manufacturer-specific gaskets, refractory panels, and termination caps it needs. We keep common replacement parts on our trucks for The Colony service calls, so most single-component repairs are completed in one visit without waiting on a parts shipment.
Common Gas Fireplace Repair Problems We See in The Colony Homes
- Rusted-through termination caps and damper assemblies. Lake wind drives moisture into every gap, so even a unit that’s only 15 years old can have a cap that’s already failing structurally.
- Cracked refractory panels and failed gaskets inside zero-clearance fireboxes. Homeowners assume a newer-looking fireplace is fine, but The Colony’s 30-to-45-year-old factory units are past their design life and the interior panels don’t last forever.
- Chase flashing separated from the chase top by clay-soil heave. The black clay under The Colony expands and contracts seasonally, and that movement transfers through the structure into the prefab chase, pulling flashing loose and letting water run down the metal flue.
- Rusted aluminum flue liners from exterior moisture intrusion. Water getting past a failed chase cover or flashing rusts liners from the outside in, which compromises draft and can create carbon monoxide risks that a visual check of the firebox alone will never catch.

FAQs – Gas Fireplace Repair in The Colony
Yes, it does. A fireplace that looks fine from the outside can have a cracked refractory panel, a deteriorated flue liner, or a rusted termination cap that you’d never see without a camera inspection. The Colony’s housing stock is largely from the 1970s through 1990s, and the factory-built fireplaces in those homes were designed to last 20 to 30 years. Most are past that. A Level 2 inspection tells you exactly what’s still safe and what needs attention before it becomes a bigger repair. Call (336) 863-3889 to schedule one.
Because The Colony sits directly on the south shore of Lewisville Lake, and the prevailing southeast wind drives moisture straight into chimney chases, termination caps, and flashing. Frisco and Carrollton get the same North Texas humidity but not the constant wind-driven lake moisture. Add in The Colony’s expansive black clay soil, which heaves and shrinks seasonally, and you have flashing that keeps separating and letting water in. It’s a compounding problem that inland suburbs rarely see to the same degree.
A Level 2 inspection covers the entire flue system, not just the part you can see from the living room. We run a camera through the aluminum flue liner inside the chase, inspect the chase top and termination cap, check the flashing where the chase meets the roof, and verify the burner assembly and gas valve are operating correctly. You receive a photo report showing everything we found, including any areas where water is getting in. For a complete quote on a Colony inspection, call us at (336) 863-3889.
Yes. We source manufacturer-specific gaskets, refractory panels, burners, and termination caps for Heatilator, Majestic, and most other factory-built brands, including units installed in the 1970s and 1980s. We also carry professional trade materials from HeatShield, Gelco, Olympia Chimney, and Famco. Many of the common components are on our trucks when we arrive in The Colony, so you don’t wait weeks for a part to ship.
Gas fireplaces produce far less creosote than wood-burning fireplaces, but that doesn’t mean they’re immune to moisture problems. The real issue in The Colony is not creosote – it’s rust. Elevated lake humidity slows drying inside the chase and on metal components, and wind-driven moisture accelerates oxidation on dampers, caps, and flue liners. If you burn gas logs frequently, we still recommend an annual inspection because moisture and corrosion are the bigger threats in a lakeside community. Schedule one by calling (336) 863-3889.
We were called to the Stewart Peninsula area for a Majestic zero-clearance gas fireplace that had stopped drafting. The termination cap was rusted through, and the chase flashing had separated from the roofline by clay-soil movement. We replaced the cap, resealed the flashing, and ran a full camera inspection on the aluminum flue liner. The fireplace drafted properly again, and the homeowner avoided a much larger repair down the road. That’s the kind of repair we see regularly in The Colony’s lakefront subdivisions.
If your gas fireplace is acting up in The Colony, call Alcott Chimney Sweep at (336) 863-3889. You’ll get a live person, a written price before we start, and a technician whose name and photo you’ll see before they arrive. Ruben Castellano built this company so you’d never have to wonder who’s coming to your door.
