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 Cap & Crown in Kirkland: What to Know First
We provide independent Gelco chimney cap and crown service in Kirkland, typically scheduling within a few business days and completing most cap replacements and crown repairs in a single visit. Every job starts with a camera-scan inspection and ends with a written price, photo documentation, and our 365-Day Done Right Promise. We’re not affiliated with Gelco - we source parts through our Haven buying network and recommend only what the flue camera actually shows.
This page is for Kirkland homeowners who already own a Gelco cap or crown and need honest diagnosis, not a sales pitch. Whether you’re in Juanita, Finn Hill, or the older brick homes near Market Street, we’ve likely serviced your exact model. Call (425) 642-3485 for a free estimate.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue caps with the welded-seam lid (Series M-100 and M-200) develop hairline cracks at the corner welds after 6-10 Kirkland winters. Rain gets in, freezes, and the lid separates from the mesh skirt. We replace with a Gelco OEM lid or, if supply is tight, a compatible aftermarket unit from our Haven network that matches the 304 stainless spec - never galvanized.
- Gelco single-flue caps with the 5/8-inch mesh (Model S-5 and S-6) clog with cottonwood seed in late spring across Kirkland’s lake-adjacent neighborhoods. The mesh was spec’d for East Coast spark arresting, not Pacific Northwest seed load. We clean the mesh in place when possible, or upsize to a 3/4-inch mesh equivalent that maintains UL 127 listing while passing debris.
- Gelco crown-mounted caps on pre-1990 Kirkland chimneys often sit on concrete crowns that were never poured with a drip edge. The cap’s mounting flange traps water against the crown spall line. We remove the cap, assess crown integrity with a hammer test, and either reseat on a repaired crown or recommend crown coating with HeatShield if the substrate is sound.
- Gelco wind-band caps (WB series) in exposed hilltop homes near Bridle Trails take sustained wind load that loosens the band tension screw. The cap tilts, creating a gap for water entry. We retorque to spec, add a stainless locknut, and document the band diameter so the next tech knows exactly what was set.
- Gelco copper-finish caps (C series) develop galvanic corrosion where the stainless base meets the copper-plated lid, especially on homes within a mile of Lake Washington’s salt-air influence. The copper flakes, the base rusts from the inside out. We replace with full 304 stainless or, if the customer wants the copper look, a pure copper cap from Copperfield with no dissimilar-metal joint.
Our Gelco Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers, checks our calendar, and books your inspection. You’ll get a text when your tech is en route.
- 2
Camera-scan inspection. We run the flue camera before touching the cap or crown. Clause 4 of the Haven Standard requires a photo record on every job, and we need to know if water damage has reached the flue liner before we quote any exterior work.
- 3
Written price, written scope. You get a line-item quote: cap removal, crown assessment, parts (OEM Gelco or Haven-network equivalent), installation, and warranty. No work starts until you approve in writing.
- 4
Parts decision with documentation. If Gelco OEM is available, we show you the part number. If we recommend aftermarket, we show you the spec sheet - 304 stainless, matching gauge, same mesh listing. The camera doesn’t lie, and neither does the invoice.
- 5
Repair and test. Cap or crown work is completed, we water-test the crown with a controlled spray, and the flue camera goes down again to confirm no debris entered during the job.
- 6
Cleanup and record. You receive printed findings, before-and-after photos, your paid invoice with warranty terms, and our 365-Day Done Right Promise in writing.

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 significant share of Kirkland’s Gelco inventory has passed through our hands. Corrine Halstead learned the trade at Apex Technical School in Manhattan and has spent well over a decade doing hands-on chimney work across the Pacific Northwest. She and her crew know the difference between a Series M-100 and M-200 without reading the stamp, and they know which Juanita Beach homes have the pre-1990 crowns that fail underneath the cap.
Our background-checked, uniformed technicians arrive with license information displayed, a named assignment, and a text when they’re on the way. Every quote is written before work starts - Haven Standard Clause 1. Every job gets a photo record - Clause 4. And if something’s not right, we make it right - the 365-Day Done Right Promise, stamped on every invoice. We also carry DuraFlex and HeatShield materials, so if your Gelco cap revealed a liner or crown problem we didn’t expect, we can address it without a second trip.
FAQs
Gelco’s original warranty on materials typically expires after the stated term, and our independent service does not affect any remaining coverage on parts we install from Haven-network suppliers. We document part numbers and install dates so you have a record if a defect appears. For warranty questions on a cap we installed, call us at (425) 642-3485 and we’ll handle the claim directly.
We source OEM Gelco when available through our Haven buying network. When Gelco lead times stretch past two weeks - common on discontinued Series M lids - we substitute a 304 stainless equivalent that matches gauge, mesh listing, and wind load spec. We show you both options and the price difference before you decide.
A cap that blows off in wind or slides down the flue needs resealing and possibly new mounting hardware, not necessarily full replacement. A cap with cracked lid welds, rust-through at the base, or mesh separation needs replacement. We determine this with a visual and hammer test during inspection, then show you photos. Call (425) 642-3485 for an exact quote - estimates are free.
A cracked crown lets water reach the flue liner and smoke chamber, where freeze-thaw cycles in Kirkland’s wet winters accelerate spalling and liner deterioration. If the camera shows no liner damage yet, crown coating can prevent the next stage. If the liner is already compromised, waiting risks a more expensive rebuild. We tell you which situation you’re in, with photos, before recommending any work.
Most Gelco cap jobs are scheduled within 3-5 business days and completed in one visit. Multi-flue caps or crown repairs requiring dry time may need a return trip. We do not promise same-day dispatch, but we do answer our phones live 24/7 and will tell you honestly where you fit on the calendar.
