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.
Gelco Chimney Cleaning in Englewood, CO | Level Two Chimney Littleton
We provide independent our Chimney Cleaning & Sweep in Englewood and inspection service across Englewood, not as a manufacturer affiliate, but as technicians who’ve worked on Gelco systems in this city’s post-war housing stock for years. The one thing that makes our Gelco work here different: we know how Englewood’s Chinook-driven freeze-thaw cycles and RAQC curtailment burn windows create failure patterns you won’t see in the same concentration anywhere else in the metro. For a written estimate on your Gelco system, call us at (720) 439-4666.
Why Englewood Residents Choose Us for Gelco Service
Corrine Halstead, our owner, learned flue sizing and draft diagnostics at Apex Technical School in Long Island City before the trade brought her west. She’s spent well over a decade applying that training on real jobs across the Denver metro, including in Englewood’s older neighborhoods where Gelco masonry fireplaces from the 1950s and 60s still see heavy winter use. Her crew has worked through Littleton and into Englewood’s core, and she’s known for walking customers through camera footage herself before any paperwork gets signed. The camera doesn’t have an opinion - it just shows you what’s there.
We source OEM or exact-match aftermarket parts for Gelco fireplaces, dampers, and caps through our Haven buying network. Because we’re independent, we’re not pushing factory service plans or warranty restrictions that don’t fit your situation. If your Gelco masonry chimney needs a full reline instead of another patch, we’ll say so, and we’ll put that in writing before any work starts. That’s Haven Standard Clause 1: written price, written scope, written warranty, delivered before the first tool comes out.
Our technicians are background-checked and uniformed, with license information on every page. You get a text when your tech is en route, and a documented photo record under Haven Standard Clause 4 - the same practice we’ve held since 2009, when most companies were still using flashlights and verbal reports.
Common Gelco Chimney Cleaning Problems We Solve in Englewood

- Cracked or spalled clay tile liners in original Gelco masonry chimneys. Englewood’s 1940s-60s bungalows near Old Englewood and Belleview often carry unlined or single-wythe brick chimneys with original clay flue tiles. The Chinook winds that sweep through at 5,300 feet can drop temperatures 40°F in hours, saturating masonry and refreezing it before the brick dries. That cycle cracks tiles at a rate lower-elevation suburbs don’t match. We see this on inspection camera as stair-step fractures or complete tile separation.
- Failed mortar crowns on Gelco brick chimneys. Snow loads on flat crowns in Englewood’s core neighborhoods, followed by rapid melt and refreeze, open mortar joints and let water infiltrate the chimney structure. A crown that looks intact from the ground often shows hairline cracking and spalling at the flue interface. We document this with photos and recommend rebuild or sealant application based on severity.
- Offset or misaligned flue tiles trapping creosote and restricting draft. Older Gelco installations in Englewood’s ranch homes sometimes settled with the foundation, shifting flue tile joints out of alignment. Creosote accumulates at these offsets, and when RAQC curtailment lifts and homeowners rush to burn, the restricted draft pushes smoke back into the room. Our Level 2 inspection catches this before you light the match.
- Rusted or seized Gelco dampers and firebox components. Denver metro’s temperature swings create condensation cycles in idle chimneys. Gelco top-mount dampers and firebox hardware from the 1970s-80s factory-built lines corrode in place, sometimes welding shut or failing to seal completely. We assess whether OEM replacement or aftermarket upgrade makes more sense.
- Heavy glazed creosote from intermittent burning patterns. Englewood homeowners who burn only during legal RAQC windows often run short, hot fires rather than sustained burns. This produces Class III glazed creosote, a hard, tar-like deposit that standard brushing won’t remove. We use mechanical removal or chemical treatment depending on thickness, always documented with before-and-after camera footage.

AfterGelco Service in Englewood: What Local Conditions Mean for Your Equipment
Here’s the pattern we see almost every winter in Englewood, and it’s tied to something no generic chimney page will tell you. The Regional Air Quality Council issues wood-burning curtailment advisories during Denver metro inversions, and Englewood homeowners - like everyone in the RAQC zone - must wait for the all-clear. When that advisory lifts, calls flood in. Homeowners on South Broadway, in Old Englewood near Federal, or in the Belleview corridor light fires they’ve been planning for days, and smoke rolls back into the living room.
What happened? The prior season’s creosote load went unchecked because the chimney wasn’t swept during curtailment. Or a cracked Gelco flue tile, opened further by Chinook freeze-thaw cycling through the fall, finally let combustion gases leak into the wall cavity. Or a crown that took snow load and rapid melt in January now channels water directly onto the smoke shelf. These aren’t separate problems. They’re Englewood-specific failure chains, and they require a sweep who knows Gelco construction well enough to trace the root cause instead of treating symptoms - which is why Chimney Repair - Englewood expertise matters here.
We got a call from a homeowner on South Broadway in Old Englewood after the latest RAQC advisory lifted - they’d tried to light a fire and smoke rolled back into the living room. Our tech found a Gelco masonry fireplace with a cracked flue tile and heavy glazed creosote about a third of the way up, plus a failed crown that had been letting water in for seasons. We swept the flue, removed the creosote, and scheduled a full reline and crown rebuild before they could safely burn again. That’s the work we do in Englewood, and it’s why we keep OEM-compatible Gelco parts and stainless reline materials stocked for fast turnaround.
Gelco Models & Products We Service in Englewood

Our technicians work on the full range of Gelco systems found in Englewood’s housing stock:
- Gelco masonry fireplace inserts and heat circulators - common in post-war Denver-area homes, often installed in the 1950s-60s ranches near Old Englewood. We handle firebox repair, damper replacement, and flue relining.
- Gelco factory-built wood-burning fireplaces from the 1970s-80s - metal chassis systems with refractory panels that crack with thermal cycling. We assess panel replacement versus full system retirement.
- Gelco multi-flue chimney caps and top-mount dampers - frequently found on 1960s ranches with multiple fireplaces. We stock replacement caps and damper mechanisms for same-visit installation when possible.
- Gelco gas log sets and vented gas fireplace systems - burner orifice cleaning, valve testing, and vent inspection per manufacturer specifications.
We source parts through our Haven buying network from Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield. If OEM Gelco components are discontinued, we specify exact-match aftermarket alternatives and explain the difference in writing. No guesswork, no “it should fit.” For Gelco sales & service questions, we’re available by phone.
Gelco Service Pricing in Englewood

Heavy glazed creosote removal adds $150-$300. Crown repair or rebuild ranges $400-$1,200.

FAQs - Gelco Chimney Cleaning in Englewood
Yes. We’ve cleaned and inspected Gelco masonry systems in Englewood’s 1940s-60s bungalows and ranches for years, including unlined chimneys and clay-tile flues that need relining. Our techs carry OEM-compatible parts for common Gelco dampers and firebox components found in this housing stock. Call (720) 439-4666 to schedule.
No. Cracked flue tiles in a Gelco masonry chimney allow combustion gases to enter wall cavities, creating fire and carbon monoxide hazards. We document the damage with camera footage, provide a written scope for repair or relining, and won’t clear the system for use until it’s safe. Call (720) 439-4666 for a free inspection.
Englewood’s RAQC curtailment pattern pushes homeowners into intermittent, short-burn cycles that produce glazed creosote faster than sustained burning. Combined with Chinook temperature swings that stress flue tiles and open new creosote-trapping offsets, the system degrades faster here than in areas with more predictable burn seasons. A Level 2 inspection each fall, before curtailment begins, is the safest approach. Call (720) 439-4666 to book.
Yes, if the concrete or mortar crown has surface cracking or minor spalling. We grind, seal, or rebuild depending on damage depth. If the crown has failed structurally or the flue interface is compromised, we recommend full rebuild with proper slope and drip edge to shed Englewood’s rapid melt-refreeze cycles. Every option is priced in writing before work starts.
Yes. Our pre-purchase Level 2 inspection includes camera-scan documentation of the Gelco flue liner, smoke chamber, firebox, and exterior crown condition. You receive a written report with photos and any recommended repair scope with pricing - critical for negotiating on Englewood’s older homes with original masonry chimneys. Call (720) 439-4666 to schedule.
