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 Liner & Rebuild in Kirkland: What to Know First
We provide independent Gelco chimney liner and rebuild service in Kirkland, typically quoting and scheduling within 24 hours of your call, with most liner replacements completed in a single day and full rebuilds taking two to three days depending on weather. Every job starts with a written price, a written scope, and a written warranty before any work begins - no exceptions, no surprises. This page is for Gelco owners in Kirkland, Juanita, and the Rose Hill area who need straight answers about what’s actually wrong with their liner, what it costs, and whether the work can wait. Call (425) 642-3485 for a free estimate.
How Gelco Products Fail - and How We Fix Them
- Gelco Ultrastar Pro flexible liners develop longitudinal seam separation after 12-18 years in Kirkland’s wet winters, especially where the flue passes through an unconditioned chase. The 316Ti alloy holds up, but the crimp-lock seam traps condensation that accelerates chloride stress corrosion. We cut back to sound metal and splice in a new Gelco or DuraFlex section with a mechanical expansion joint at the joint.
- Gelco stainless rigid tee assemblies in older Kirkland homes near Juanita Beach suffer bottom-tee rot from acidic condensate pooling where the tee meets the smoke chamber shelf. The tee body looks fine from above; the camera finds the thinning. We replace with a Gelco OEM tee or a HeatShield Cerfractory foam rebuild of the shelf if the tee itself is still serviceable.
- Gelco ProForm rectangular liners distort at the thimble connection in masonry chimneys with settled crowns, common in 1970s Kirkland split-levels. The rectangular form tries to hold shape while the surrounding brick shifts. We pull the liner, stabilize the thimble with a poured crown repair using Copperfield crown seal, and reinstall with a Gelco flex adapter to absorb future movement.
- Gelco top plate and storm collar assemblies leak at the silicone bead after five to seven Pacific Northwest winters, not from the metal but from UV-degraded sealant that lets water track behind the plate. Water stains the exterior chase or interior drywall below. We remove the assembly, inspect the flue wall for hidden spalling, and reinstall with fresh high-temp silicone and a proper drip edge.
- Gelco smooth-wall liners in oil-to-gas conversion jobs (common in Rose Hill and North Rose Hill) were often sized for the original appliance BTU and run too cold with modern high-efficiency equipment. The result is Class III glazed creosote that a brush won’t touch. We verify appliance BTU against liner diameter per NFPA 211, resize with a properly matched Gelco or Olympia Chimney liner, and document the new sizing for the homeowner’s records.
Our Gelco Chimney Liner & Rebuild Process

- 1
Level 2 camera inspection. We run a chimney camera the full flue length, document liner condition, joint integrity, and any offset or distortion. You get the footage and a written finding before we talk price.
- 2
Written scope and price. We deliver a line-item quote: parts, labor, disposal, and warranty terms. Clause 1 of the Haven Standard requires this in writing before work starts. No verbal estimates, no “we’ll see when we get in there.”
- 3
Parts decision. For Gelco repairs, we source OEM Gelco components through Haven’s buying network when available. If Gelco lead times stretch past what’s reasonable for your heating season, we specify DuraFlex or HeatShield equivalents that match or exceed OEM spec and note the substitution in writing.
- 4
Repair or rebuild. Liner replacement: pull old, install new, connect appliance with proper adapter, seal top plate. Partial rebuild: replace damaged courses, pour new crown, reinstall liner. Full rebuild: dismantle to sound masonry, reconstruct with matching brick, install new Gelco or specified liner system.
- 5
Smoke test and documentation. We pressure-test or smoke-test per local code, then deliver a photo record of completed work, product labels, and warranty card. Clause 4 of the Haven Standard requires this documentation on every job.
- 6
365-Day Done Right Promise. If anything in our scope fails due to workmanship or materials, we make it right. The warranty terms are on the same page as the price.

Why Kirkland Homeowners Call Level Two Chimney Kirkland for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a meaningful share of those have been Gelco systems in Kirkland’s 1960s-through-1990s housing stock. Corrine Halstead learned the trade at Apex Technical School in Manhattan and has logged well over a decade of hands-on chimney work across the Pacific Northwest. She and her crew know the local pattern: older homes near Juanita Beach where gas conversions left undersized liners, split-levels with settled crowns, and the particular way Gelco seams age in our wet climate.
Our technicians are background-checked, uniformed, and assigned by name. You get a text when they’re on the way, a license number on every page, and a live person when you call - 24 hours a day. The camera doesn’t lie, and neither does the invoice. We also service DuraFlex, HeatShield, Olympia Chimney, Famco, and Copperfield systems, so if your Gelco parts are backordered, we have qualified alternatives ready and documented.
FAQs
No. As an independent Gelco service provider, we follow installation practices that meet or exceed Gelco’s published guidelines. Manufacturer warranties cover defects in materials, not who performed the installation, provided the work meets code and the product was installed per spec. We document every step so you have that proof if needed. Call (425) 642-3485 for a free estimate.
Most full liner replacements are completed in one day. Full chimney rebuilds take two to three days depending on weather and masonry cure times. We don’t rush masonry work - a proper crown pour needs dry conditions to set. We’ll give you a firm schedule in the written quote. Call (425) 642-3485 to book.
We source Gelco OEM through Haven’s buying network when lead times are reasonable. If Gelco backorders stretch past heating season, we specify DuraFlex or HeatShield equivalents that match or exceed OEM spec and note the substitution in your written scope. You approve every part before it goes in. Call (425) 642-3485 for details.
The camera decides. Isolated seam separation or a rotted tee section often warrants targeted repair. Multiple failure points, spalling flue walls, or a shifted chimney structure mean rebuild. We show you the footage, explain what we’re seeing, and give separate prices for each option so you can choose. Nothing is recommended without camera evidence you can see for yourself. Call (425) 642-3485 for a free inspection.
A compromised liner lets combustion gases, including carbon monoxide, leak into wall cavities or living space. In Kirkland’s heating season, that’s a real hazard, not a sales pitch. Glazed creosote also increases chimney fire risk. That said, if the camera shows minor surface rust with intact seams, we’ll tell you honestly that it can wait a season with annual monitoring. Call (425) 642-3485 and we’ll show you what we found.
