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 McKinney Homeowners Choose Gelco Chimney Cleaning
We provide independent Gelco chimney cleaning and repair service across McKinney, TX, with NFPA 211 Level 2 camera inspections included on every visit and a written price delivered before any work begins. Our crews handle Gelco prefabricated wood-burning fireplaces, direct-vent gas units, and their replacement components as an independent service provider - not an authorized Gelco dealer - which means we source factory-correct parts while recommending only what your system actually needs. Call (469) 429-2623 for a free estimate.
McKinney’s explosive growth over the past two decades packed subdivisions like Stonebridge Ranch and Craig Ranch with builder-grade Gelco prefab fireplaces that are now reaching the 10-20 year mark with little or no professional attention. These aren’t masonry systems; they’re zero-clearance cabinets with stainless steel flue pipe, refractory panels, and galvanized chase covers that deteriorate on a completely different timeline than brick chimneys. We’ve cleaned and repaired thousands of them across Collin County since 2009, and we’ve learned which Gelco components fail first in North Texas conditions.
Why Trust Level Two Chimney McKinney for Your Gelco Chimney Cleaning?
Corrine Halstead, our owner, learned the trade at Apex Technical School in Manhattan before years of field work across Collin County sharpened her eye for what inspections miss when technicians move too fast. She spent a stretch working older homes near McKinney’s Historic Downtown district where deteriorating mortar joints taught her more than any classroom could. That same discipline - camera down the flue, findings shown before any dollar is quoted, scope and price written on paper before scheduling - is how every Gelco job runs today. The camera doesn’t lie, and neither does the written quote.
Our technicians are background-checked, uniformed, and assigned by name. You get a text when they’re on the way, and their license information is on every page. We stock Gelco-compatible firebox panels, grates, dampers, caps, and pipe sections because aftermarket lookalikes often misalign in these prefab cabinets. Every job includes a documented photo record under Haven Standard Clause 4 - not an optional add-on, but standard practice we’ve run since 2009. The 365-Day Done Right Promise backs every repair: if it’s not done right, we make it right.
Common Gelco Chimney Cleaning Problems We Fix in McKinney

- Cracked refractory firebox panels and warped grate bars. Builder-grade Gelco fireboxes in McKinney subdivisions were sold as standard features, not heavy-use appliances. Repeated burn cycles - even occasional ones - stress the refractory panels until they crack or spall. We see this constantly in Stonebridge Ranch units that have never been professionally inspected. A Level 2 camera inspection lets us map every crack and measure panel thickness before quoting replacement.
- Damaged or missing spark-arrestor screens and cap assemblies. Gelco caps and screens are the first line against water and debris, but North Texas hail knocks them loose and McKinney’s chimney swifts (protected May-October) pull at mesh to build nests. On a Gelco prefab in west McKinney, our tech found the spark-arrestor screen had rusted loose after a hailstorm and was sitting down inside the flue. We pulled the cap, cleaned the flue, and installed a correctly sized replacement. The homeowner had been smelling cold draft on still evenings; the new cap and a free-moving damper stopped it, and the Level 2 inspection confirmed the firebox panels were still sound.
- Rust-through or pitting on steel chimney pipe and top plates. Gelco’s galvanized chase covers and steel top plates fail predictably at 10-15 years in McKinney’s climate. When the 2021 freeze hit, residents fired up long-neglected systems and we fielded emergency calls from homeowners who’d never noticed their chase cover had rusted through. Water infiltration rots the wood-framed chase from inside out. We bundle chase cover replacement with cleaning calls in these neighborhoods because the two problems arrive together.
- Failing dampers and misaligned damper frames. Gelco dampers in prefab cabinets lose their seal as frames warp or rust. Cold downdrafts on McKinney’s 30-40 genuinely cold nights per year aren’t just uncomfortable - they pull conditioned air out of your home continuously. We check damper operation, frame squareness, and seal contact during every Level 2 inspection.
- Class III glazed creosote in rarely-used flues. McKinney’s short heating season means many Gelco units sit idle for 10-11 months, then get fired hard when a cold snap hits. That intermittent heavy use pattern produces glazed creosote that’s harder to remove than the powdery Class I buildup seen in regularly-swept systems. We rotary-clean these flues and document the creosote class in your photo record.

AfterGelco Parts & Our Repair-vs-Replace Approach
We source correct Gelco-style OEM replacement parts through Haven’s buying network - firebox panels, grates, dampers, caps, and pipe sections - because fit matters in prefab cabinets where eighth-inch tolerances affect draft and safety. Aftermarket alternatives often cost less and fail faster, or they don’t seat properly against factory gaskets.
When a Gelco firebox or flue has structural damage that would cost more to rebuild than the unit’s remaining service life is worth, we tell you straight and quote replacement rather than selling a patch job. That assessment comes with camera footage you can see yourself and a written second opinion at no charge if you want to compare our scope against another estimate. Call (469) 429-2623 to schedule.
Our Gelco Service Process - Step by Step

- 1
Diagnosis with NFPA 211 Level 2 inspection. We run a camera down the full flue length, photograph the firebox panels, damper assembly, smoke chamber, and termination cap. For Gelco prefabs, we specifically document chase cover condition, spark-arrestor mesh integrity, and any water staining on the flue pipe interior. You see the footage before we quote.
- 2
Written scope and price delivered. Haven Standard Clause 1 requires a written price, written scope, and written warranty before anyone starts - not after the tech is already in your home. For Gelco work, we itemize parts by series compatibility and labor by access difficulty (roof pitch, chase height, attic routing).
- 3
Repair or install with correct components. We stock Gelco-compatible panels, grates, dampers, and caps locally for fast turnaround. Technicians carry common sizes to most McKinney appointments. If your unit needs a specialty part, we order through Haven’s network and schedule completion once it arrives - never billing storage or rush fees we didn’t disclose upfront.
- 4
Post-work testing and documentation. We verify draft, damper seal, and cap security after every Gelco repair. Smoke chamber and flue are camera-checked a second time to confirm no debris remains. Your documented photo record - Haven Standard Clause 4 - is completed before we leave.
- 5
Warranty registration. The 365-Day Done Right Promise is stamped on every job. Materials carry their manufacturer warranty where applicable. You get both in writing.
Gelco Products We Service & Install in McKinney
We work on Gelco prefabricated wood-burning fireplaces with stainless steel chimney systems - the standard builder package across McKinney-area subdivisions built 1995-2015. We also service Gelco gas fireplace and insert units with direct-vent or B-vent terminations, plus their OEM chimney caps, top plates, spark-arrestor screens, firebox panels, and grates. Our local inventory covers the most common Gelco cabinet sizes found in Stonebridge Ranch, Craig Ranch, and Painted Tree installations. For less common configurations or full replacement, we source through Haven’s network with DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield materials as appropriate.
We Also Service These Brands

Level Two Chimney McKinney is independently owned and operated, not single-brand dependent. We service and install DuraFlex chimney liner systems, HeatShield cerfractory flue resurfacing, and components from Olympia Chimney, Famco, and Copperfield - whatever system your home actually has, we inspect to the same Level 2 standard and quote with the same written transparency.
FAQs - Gelco Chimney Cleaning Service in McKinney
Is Level Two Chimney McKinney authorized by Gelco?
No. We are an independent Gelco service provider, not an authorized dealer or factory representative. We source OEM-compatible and factory-correct replacement parts for Gelco systems, but we have no affiliation with Gelco Manufacturing. Our independence means we recommend only the work your system needs, not what a brand program pushes.
Do you use genuine Gelco/OEM parts?
We stock and source correct Gelco-style OEM replacement parts - firebox panels, grates, dampers, caps, and pipe sections - because aftermarket lookalikes often misalign in prefab cabinets where tolerances are tight. When OEM isn’t available, we use quality equivalents that meet or exceed factory specifications and we document what was installed in your photo record.
How long does Gelco service take?
A standard Gelco chimney cleaning with Level 2 inspection takes 60-90 minutes. Firebox panel replacement or damper repair typically runs 2-3 hours. Chase cover replacement on two-story McKinney homes adds time for roof access and safety setup. We give you a time estimate in writing before scheduling, and a text when your technician is en route.
What Gelco models/series do you cover?
We service the full range of Gelco prefabricated wood-burning fireplaces with stainless steel chimney systems, Gelco gas fireplace inserts with direct-vent or B-vent terminations, and all associated OEM components including caps, top plates, spark-arrestor screens, firebox panels, and grates. If you’re unsure of your model, we identify it during the Level 2 inspection at no extra charge.
Will service void my Gelco warranty?
Manufacturer warranties on prefab fireplaces typically require professional service but don’t mandate dealer-only work. As an independent provider, we follow NFPA 211 standards and use correct components, which preserves warranty standing in most cases. We document our work with photos and written scope - the same documentation insurers and manufacturers request when claims arise.
How much does Gelco chimney cleaning cost in McKinney?
Gelco chimney cleaning with Level 2 inspection in McKinney typically runs $189-$279 depending on flue height, roof access, and creosote condition. Firebox panel replacement ranges $340-$580. Chase cover replacement on standard prefab chases runs $420-$750. We deliver a written, itemized price before any work starts - no exceptions. Call (469) 429-2623 for an exact quote; estimates are free.
My Gelco fireplace smells like smoke on windy days even when it isn’t lit - what’s wrong?
A missing or damaged spark-arrestor screen, rusted cap, or stuck-open damper lets outside air push down the flue, carrying old soot odor into your home. We see this constantly on Gelco prefabs in McKinney after hail season. The Level 2 inspection identifies which component failed, and we quote the specific repair - cap, screen, damper, or combination - with footage you can see for yourself.
How do I know whether my Gelco firebox panels can be repaired or the whole unit needs to come out?
We measure crack width, panel thickness, and heat exposure pattern during the Level 2 inspection. Hairline cracks in otherwise thick panels often don’t require replacement. Panels cracked through, spalled (flaking), or thinned below 3/8 inch need replacement - and if the steel wrapper behind them is heat-damaged, replacement of the full unit is usually more cost-effective than rebuilding. We show you the camera footage and explain both options with written prices for each.
Does my Gelco prefab chimney need a different kind of sweep than a masonry chimney?
Yes. Prefab flues are stainless steel pipe, not clay tile, so we use poly or wire brushes sized to the pipe diameter - never masonry-rated tools that can score or deform thin metal. The firebox is refractory panel, not brick, so we clean without impact tools that crack panels. The inspection focuses on chase cover water intrusion and damper seal, problems masonry chimneys don’t have. Our Chimney Cleaning & Sweep services use a Level 2 protocol adapted for your system type.
After hail or a big storm, what should I have checked on my Gelco chimney?
Cap position and screen integrity first - hail knocks Gelco caps askew and dents mesh until it gaps. Then chase cover for rust-through or fastener loosening. Then flue pipe interior for water staining that indicates cover failure. We bundle all three checks into a post-storm Level 2 inspection, and we document everything for insurance if you need to file.
Can you get Gelco-compatible replacement parts, or do I have to buy a whole new fireplace?
We stock and source correct Gelco-compatible parts - panels, grates, dampers, caps, pipe sections - locally for fast turnaround. Full replacement is only recommended when structural damage exceeds what parts can fix, or when discontinued models make sourcing uneconomical. We quote both paths when both exist, and we never pressure toward the more expensive option. Call (469) 429-2623 to discuss your specific unit.
