Gelco Chimney Cleaning in Englewood, CO
We provide independent Gelco service across Englewood, CO, from clay tile liner repair to stainless liner installation and cap replacement. What sets our Gelco work apart in Englewood is the housing itself: most calls here land on pre-1950 brick chimneys that were never lined for modern combustion, so cleaning and relining frequently arrive in the same visit. Our technicians have up to 14 years of experience with these older flues. Call (888) 320-6023. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.
Why Englewood Residents Choose Us for Gelco Service
Oasis Chimney Sweep is an independent Gelco service provider. We’re not affiliated with the manufacturer and we don’t claim any authorization from it. Our knowledge of Gelco chimney caps, clay flue tile liners, and stainless steel liners comes from working on them in Englewood homes, block after block, through Front Range winters.
What that means for you is simple: we know how these components fail here and what a correct repair looks like. We service Gelco equipment with quality parts that fit it, sourced from trusted suppliers for compatibility and safety rather than whatever is cheapest that week. Same for the other professional-grade lines we work with, including DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield.
You get one contractor for the sweep, the inspection, and the repair. No handoffs, no gaps in accountability. Scheduling is straightforward: tell us what your fireplace is doing, and we’ll book a visit that fits. Gelco work is a core part of what we do, and in Englewood it’s most of what we see.

Common Gelco Chimney Cleaning Problems We Solve in Englewood
- Cracked clay tile liners. Freeze-thaw cycles along the Front Range open hairline cracks in Gelco clay tile liners, and each cycle widens them. Once cracked, creosote and moisture reach the brick behind the tile, so a cleaning that turns up cracked tile usually means a liner decision rather than another sweep.
- Chimneys with no liner at all. Plenty of pre-1950 Englewood homes have original single-wythe brick chimneys that were never lined. When a gas appliance is later retrofitted to that flue, the brick absorbs heat and acidic moisture directly, and deterioration follows.
- Eroded mortar joints. Acidic flue gases and moisture eat away the mortar between Gelco clay tiles. In gas-converted fireplaces, where exhaust is wetter and more acidic than a wood fire’s, that erosion runs faster.
- Cracked crowns. Englewood’s freeze-thaw pattern splits crowns, and a split crown lets water straight into the chimney structure. Crown repair is one of our core services for exactly this reason.
- Caps that no longer seal. Wind-driven rain and downdrafts on the dry, windy Front Range work at a loose or corroded Gelco chimney cap until it stops keeping water and animals out.
Gelco Service in Englewood: What Local Conditions Mean for Your Equipment
Englewood’s chimney trade is shaped by its dense inventory of pre-1950 brick bungalows and Tudor cottages along the South Broadway corridor and Old Englewood. Many of those chimneys were built as single-wythe brick, with no liner sized for modern combustion. Gas fireplaces and furnaces were retrofitted into them decades later, and the flue was often left as it was. Neighboring suburbs like Littleton and Centennial are dominated by newer construction with factory-built metal flues, so the reline-and-masonry-repair workflow belongs distinctly to Englewood.
For Gelco owners, that history shows up as a cleaning visit that becomes a safety inspection. The flue gets swept, the camera goes up, and what comes back is often cracked tile, missing mortar, or bare brick where a liner should be. The dry, windy Front Range adds downdrafts and creosote patterns that differ from lower-elevation markets. It’s why we treat a Gelco cleaning in Englewood as a diagnostic visit first and a brush second.
Gelco Models & Products We Service in Englewood
We service the three Gelco product types Englewood homeowners actually have on their roofs and inside their flues: Gelco chimney caps, Gelco clay flue tile liners, and Gelco stainless steel chimney liners. A cap that’s rusted through gets replaced with one that fits the flue opening correctly. Cracked clay tile gets assessed for tuckpointing, ceramic resurfacing with HeatShield, or a stainless liner, depending on how far the damage runs. Where a liner is the right answer, we specify DuraFlex flexible liner systems because they fit older or irregular flue shapes that a rigid liner won’t follow.
We source OEM-equivalent Gelco replacement parts from trusted suppliers. We don’t claim to stock them, and we won’t tell you a part is genuine Gelco factory stock. What we will tell you is exactly what’s going in your chimney and why.

AfterGelco Service Pricing in Englewood
Every Gelco job in Englewood is priced per job by a written estimate. The estimate is free, and it holds the final price, so you’re not guessing after the work starts.
What drives the number:
- The scope of the inspection. A Level 2 inspection, which is what an older Englewood chimney usually needs, covers more than a basic visual check.
- Whether the repair is a crown repair, tuckpointing, a HeatShield resurfacing, or a full stainless liner installation.
- Access and condition of the flue, including whether the existing tile can be salvaged.
- Chimney rebuilding, if the damage has reached the masonry itself.
You’ll see the findings before you see a price. Camera inspection and a photo report come with the estimate, so nothing is recommended that you can’t look at yourself. Call (888) 320-6023 for an exact quote. Estimates are free.

FAQs – Gelco Chimney Cleaning in Englewood
Because Englewood’s freeze-thaw cycles are harder on clay tile than a milder climate is. Water wicks into the tile and mortar, freezes overnight, expands, and opens the crack a little wider each time. Add the acidic moisture from a gas-converted fireplace and the tile erodes from the inside as well. Call (888) 320-6023 to have your liner assessed.
A Level 2 inspection examines the entire flue, not just the firebox and the visible section. We run a camera through the flue to check the condition of the Gelco clay tile liner, the mortar joints, and any gaps, then inspect the crown, cap, and exterior masonry. You get photos of what we found.
Often, yes. If the surrounding brick is sound, HeatShield ceramic resurfacing can restore a damaged liner, and a DuraFlex stainless liner can be installed inside the existing flue. Rebuilding is the answer when the masonry itself has failed. We recommend it only when repair is no longer safe or cost-effective.
Wind drives rain sideways into the flue and pulls at the cap’s fasteners, and the dry air works on seams and joints over time. A cap that’s loose, cracked, or corroded stops doing its job, which lets water and animals in. We check it on every visit and replace it when it’s past sealing.
Yes, for older brick chimneys that show spalling or water staining. A breathable waterproofing treatment keeps liquid water out of the brick while letting moisture vapor escape, which matters through Englewood’s winter wet-and-freeze cycle. We’ll tell you on inspection whether your chimney needs it or can wait.
Pricing is set per job by a written estimate, and the estimate is free. A straightforward sweep sits at the low end; a Level 2 inspection with crown repair or a liner installation runs higher because of the scope and materials. Call (888) 320-6023 and we’ll book an estimate.
