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 Chimney Cleaning & Sweep in Bellevue: What to Know First
We provide independent Gelco chimney cleaning and sweep in Bellevue, typically scheduling within a week during the pre-burning season rush and a few days in slower months. A standard Gelco system inspection and cleaning runs $189-$289 for most Bellevue homes, and we deliver a written price before any work starts - not after we’re in your living room. This page is for Gelco owners in Bellevue who need their flue swept, their liner inspected, or their smoke chamber checked before the wet season sets in. Call (425) 696-0387 for a free estimate, or read on for what we’ve learned servicing Gelco products in this market.
How Gelco Products Fail - and How We Fix Them
- Gelco Pro-Series top-sealing dampers collect moisture in the hinge pocket because the seal geometry traps Pacific Northwest condensation. We see this in Bellevue’s Lakemont and Somerset builds where the damper sits above a long, cool flue run. Our fix: remove the damper assembly, clean the hinge mechanism with a non-corrosive solvent, reseat the silicone gasket, and test seal integrity with a smoke pencil. If the cast-aluminum frame has oxidized, we document it with the camera and quote replacement - no surprises.
- Gelco Multi-Flue chimney caps with welded-seam construction develop pinhole corrosion at the weld lines where dissimilar metals meet salt-laden Bellevue air. The cap looks fine from the ground, but water drips through the seam onto the flue tile below. We spot this with the camera scan, not a binocular inspection from the driveway. Replacement uses a cap with fully-seamed construction or stainless-steel upgrade through our Haven buying network.
- Gelco stainless liner systems in pre-1990 Bellevue masonry often show creosote buildup at the flex-to-rigid transition joint because the original fireplace throat was never designed for the reduced diameter. Class III creosote - the hardened, tar-like stuff - forms right at that joint where gas velocity drops. We remove it with rotary chain flailing, not brushing, then check the joint for gaps that would let creosote fall back into the smoke chamber.
- Gelco Pre-Fab chimney chase covers in the Crossroads and Lake Hills areas sag between support ribs after 12-15 years of snow load and thermal cycling. Water pools, rusts the mounting flange, and leaks into the chase where it meets the manufactured chimney pipe. We measure the deflection, photograph the rust pattern, and replace with a thicker-gauge cover - 24-ounce copper or 304 stainless - fabricated to the actual chase dimensions, not a stock size.
- Gelco spark arrestor screens on wood-burning systems clog with cottonwood seed in late spring and creosote flake in fall, restricting draft enough to push smoke into the room on cold starts. Bellevue’s mature tree canopy makes this worse than eastern King County. We pull the screen, ultrasonic-clean it or replace if the mesh is degraded, and check that the arrestor frame hasn’t warped from overheating - a failure mode that voids the warranty if not caught early.
Our Gelco Chimney Cleaning & Sweep Process
- 1
Call and schedule. A live person answers, checks availability, and notes your Gelco model if you know it. We don’t use voicemail or web-form queues.
- 2
NFPA 211 Level 2 inspection on arrival. Camera down the flue, photo record started, condition documented before we touch anything. The camera doesn’t guess. Neither do I.
- 3
Creosote and soot removal matched to what we found. Standard brush sweep for Class I and II deposits. Rotary chain or chemical treatment for Class III glazed creosote - common in Gelco liners where draft has been marginal.
- 4
Parts decision if needed. OEM Gelco when the warranty requires it; quality aftermarket from Olympia Chimney or Famco when it doesn’t, sourced through our Haven buying network to keep the price honest. Written scope, written price, written warranty - Clause 1 of the Haven Standard.
- 5
Post-work camera verification and test burn. We run the camera again to confirm clear flue, proper draft reading, and no debris left in the smoke chamber. Photos go to your record archive under Clause 4.
- 6
Cleanup, documentation, and 365-Day Done Right Promise. Written report with photos, readings, and any recommendations ranked by urgency. You know what can wait and what can’t.

We don’t upsell - if your liner’s in good shape, we say so, show you the camera footage, and schedule next year’s sweep. Call (425) 696-0387 for an exact quote. Estimates are free.
Why Bellevue Homeowners Call Emberly Chimney Cleaners Bellevue for Gelco Work
We’ve swept and inspected more than 38,000 chimneys since 2009, every one with a written price before work started and a documented record when done. Corrine Halstead and her crew have been servicing Bellevue properties for several years now, including older wood-burning fireplaces in Lakemont where the homes see real use through the wet season. When a Gelco part needs replacement, we source from DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield through our Haven buying network - not a single-vendor lock. The 365-Day Done Right Promise means if it’s not right, we make it right. And our Free Second Opinion on any written estimate lets you verify what another company told you, with camera evidence you can see yourself.
FAQs
No. Routine cleaning and inspection by a qualified technician does not void Gelco’s product warranty. What voids it is unqualified modification, incorrect part substitution, or failure to maintain the system per the manual. We document our work to manufacturer standards and flag any warranty-critical conditions we find. Call (425) 696-0387 if you need documentation for a warranty claim.
We source both. OEM Gelco when the warranty or fit demands it; quality aftermarket from Olympia Chimney, Famco, or Copperfield when the specification allows and the price advantage passes to you. We specify which in the written scope before you approve anything. No bait-and-switch on parts.
The camera shows us. We look for seam separation, corrosion pitting, or deformation that reduces flue diameter by more than 10 percent. Spot damage often permits localized repair; multiple failure points or degraded stainless below 26 gauge usually means replacement. We show you the footage, explain the threshold, and rank options by cost and safety - never pressure. Call (425) 696-0387 to schedule the inspection.
Annually if you burn regularly during the heating season, or after every cord of wood. Bellevue’s wet climate means longer shoulder seasons where marginal draft causes incomplete combustion and faster creosote buildup. If you use the fireplace only occasionally, every two years with a Level 2 inspection in between is reasonable. We note the creosote class and draft reading each time so you can track the trend.
Class I creosote becomes Class III, which is harder to remove and more flammable. Draft degrades, smoke stains the firebox, and in worst cases a chimney fire cracks the flue liner or damages surrounding structure. Carbon monoxide risk rises if the flue is partially blocked. The camera inspection tells you exactly where you stand - no guesswork, no scare tactics. Call (425) 696-0387 for a free estimate and we’ll show you what we find.
