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.

AfterGelco Fireplace Services in Littleton: What to Know First
Level Two Chimney Littleton provides independent Gelco fireplace services throughout Littleton, from routine gas fireplace service to firebox repair and fireplace conversion. Most Gelco jobs we book are completed within a week, and every one starts with a written price before any work begins - no exceptions. We’re not affiliated with Gelco; we service their products because they’ve been common in metro Denver builds since the early 2000s, and our techs know where the weak points hide. If you own a Gelco gas insert, wood-burning unit, or pre-fab fireplace in Littleton, call us at (720) 439-4666 for a free estimate with documented camera inspection included.

How Gelco Products Fail - and How We Fix Them
- Gelco Log Sets (GL-18, GL-24 series): The silica sand beneath the burner ports packs down after three to five seasons of Front Range heating cycles, choking gas flow and producing lazy yellow flames that carbon up the ember bed. We pull the set, regrade the sand to factory depth, and replace any pitted burner tubes with OEM or Precision Flame aftermarket parts - whichever the customer prefers, priced in writing first.
- Gelco Direct-Vent Inserts (GDV-33, GDV-40): The flex termination collar on early GDV units cracks where it meets the thimble, especially in Littleton’s south-facing exposures where UV and freeze-thaw cycling hit hardest. We don’t caulk over it. We replace the collar with a stainless upgrade from our Haven buying network and pressure-test the seal before we leave.
- Gelco Wood-Burning Fireplaces (GW-36, GW-42): The refractory panels in the firebox develop hairline checking that widens into spalling after repeated thermal shock - common in Columbine Knolls homes where owners burn nightly November through March. We map the damage with the camera, quote panel replacement or a HeatShield resurfacing if the steel wrapper is still sound, and document everything under Haven Standard Clause 4.
- Gelco Dampers (GD-R36, GD-R42): The cast-aluminum throat plate seizes when creosote drips from the smoke chamber above and bakes onto the pivot pin. We see this on wood units that haven’t been swept in two-plus seasons. Our fix: remove the plate, ultrasonic-clean the pin and bushing, or replace with a Lock-Top or Lyemance energy-top damper if the frame is warped.
- Gelco Pilot Assemblies (across gas lines): The thermopile output drops below 325 mV after about eight years, which is right when the main valve starts dropping out mid-burn. We test millivolt output under load, not just open-circuit, and replace with a Robertshaw or OEM White-Rodgers assembly - your call, with both prices on the page before we order.
Our Gelco Fireplace Services Process
- 1
Call and schedule. A live person answers, 24/7. We book a window, text you when the tech is en route, and send a named, background-checked technician in uniform - license number on the page, not hidden.
- 2
Camera-scan inspection. NFPA 211 Level 2 inspection with full flue documentation. For gas units, we also check gas pressure, manifold pressure, and thermopile output. For wood units, we classify creosote buildup and inspect liner condition. The camera doesn’t have an opinion - it just shows you what’s there.
- 3
Written price, written scope. Before any wrench turns, you get a fixed price, the exact work listed, and the warranty terms. Haven Standard Clause 1: have it in writing. No surprises, no “we found something else” add-ons after the fact.
- 4
Parts decision. If your Gelco needs a component, we quote OEM and quality aftermarket options side by side - Gelco factory parts through our Haven buying network, or DuraFlex, HeatShield, or other proven equivalents when they make sense. You choose.
- 5
Repair and test. We complete the work, run the unit through its full cycle, check CO levels at the face, and verify draft or venting performance. Gas units get combustion analysis; wood units get a clean flue and documented photo record.
- 6
Documentation and follow-up. You leave with photos, readings, the written warranty, and our direct line. The 365-Day Done Right Promise applies automatically - if it’s not right, we make it right.

Why Littleton Homeowners Call Level Two Chimney Littleton for Gelco Work
We’ve cleaned and inspected chimneys throughout Littleton since 2009, including older homes in Columbine Knolls where masonry fireplaces still see heavy use through the long Front Range winters. Corrine Halstead and our crew know Gelco products because we’ve worked on hundreds of them - not from a manual, from pulling the units apart and seeing where they fail in real Colorado conditions.
Our difference is documentation. Haven Standard Clause 4 requires a photo record on every job, and we’ve done that since 2009 - years before it became standard language. You see what we see before you sign anything. The 365-Day Done Right Promise means if we miss something, we fix it. And because we source materials through our Haven buying network - Gelco, DuraFlex, HeatShield, Olympia Chimney, Famco, Copperfield - we can offer honest options instead of pushing whatever’s on the truck.
Background-checked, uniformed technicians. License number on the page. A text when we’re on the way. And a live person on the phone, any hour.
FAQs
No. As an independent Gelco service provider, we use OEM or equivalent parts and document our work, which satisfies manufacturer warranty requirements for routine service and most repairs. We keep parts receipts and service records that you can submit if a factory claim ever arises. If your unit is still under original factory warranty, we’ll flag that before we start and note it on your written scope. Call (720) 439-4666 and we’ll check your serial number against Gelco’s coverage periods.
Most common Gelco parts - pilot assemblies, burner tubes, refractory panels - ship to our Littleton warehouse within three to five business days through our Haven buying network. Some GDV direct-vent termination collars we stock locally because the UV cracking is that predictable. If your part is backordered, we quote the aftermarket equivalent (often DuraFlex or HeatShield) with full disclosure and your approval. We don’t start the clock on your job until the part is in hand and your written price is signed.
Repair makes sense when the firebox wrapper is sound, the flue liner is intact, and the repair cost is under roughly 40% of a comparable new insert installed. We make that call with camera evidence, not a sales pitch. If the steel firebox is rusted through, the chimney liner is unlined clay tile in poor condition, or the unit is pre-1990 and parts are obsolete, we’ll show you why replacement is the honest recommendation - and we’ll still give you a Free Second Opinion on any competitor’s replacement quote. Call (720) 439-4666 for a documented inspection.
Gas Gelco units should be serviced annually before heating season - the NFPA 211 recommendation, and what most home insurers expect if you ever file a claim. Wood-burning Gelco fireplaces need a Level 2 inspection and sweep every year if burned regularly, or every cord of wood burned, whichever comes first. In Littleton’s dry climate, creosote builds faster than on the coasts because there’s less moisture to keep it loose. Skip a season and you’re gambling with a chimney fire or CO backup. We send reminder texts in August - call (720) 439-4666 to get on the list.
Yes, and we do this regularly in Littleton homes where the homeowner wants the convenience but the existing chimney is marginal for wood. We inspect the flue liner condition first - no conversion happens without camera proof it’s safe. Then we quote the insert, gas line extension, and permit as one fixed price. The reverse conversion (gas to wood) is also possible but rarer; it requires a new liner sized to the fireplace opening and Littleton building permit. Either way, you get the written scope and price before we start. Call (720) 439-4666 for a free estimate.
