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 Olympia: What to Know First
We provide independent Gelco chimney liner and rebuild service in Olympia, with most Gelco liner replacements booked within a week and full rebuilds scheduled after a camera inspection confirms the scope. Every job starts with a written price before any work begins, backed by our 365-Day Done Right Promise. This page is for Gelco owners in Olympia, Lacey, Tumwater, and the surrounding South Sound area who need liner replacement, partial rebuild, or full chimney rebuild on a Gelco-equipped system.

How Gelco Products Fail - and How We Fix Them
- Gelco stainless liners in the 316Ti series develop crevice corrosion at the overlap seams where Olympia’s marine air traps moisture against the metal. We see this most in homes within two miles of Budd Inlet or along the Eld Inlet shoreline. Our fix is a full 316Ti replacement with sealed circumferential welds, or a switch to a higher-grade alloy if the flue gas chemistry warrants it.
- Gelco flexible liners in the ProFlex line suffer compression fatigue where they make the transition from vertical flue to smoke chamber, especially in 1980s Olympia builds with offset chimney throats. The accordion pleats flatten and tear. We replace with a correctly sized ProFlex or, if the offset is severe, reroute with rigid sections and a custom-fabricated transition.
- Gelco UL-listed top-mounted dampers integrated with their liner systems seize in the open position after five to seven winters of Pacific Northwest rain cycling through freeze-thaw. The cast-aluminum frame cracks at the pivot boss. We source the correct Gelco damper body or machine a stainless replacement that mates to the existing liner collar without disturbing the surround.
- Gelco smooth-wall liners in the Pre-Insulated series show jacket saturation in Olympia’s older homes where roof crickets leak or flashing was never properly step-flashed. The insulation pack holds water like a sponge, accelerating outer-wall rust. We strip the saturated liner, repair the water entry, and reinstall with a proper drainage plane per the manufacturer’s wet-location addendum.
- Gelco connector pipes from woodstove to liner work loose at the tee connection where thermal expansion meets the South Sound’s frequent low-temperature startup cycles. The 24-gauge seam separates. We replace with a heavier 22-gauge fabricated tee, properly anchored, and we document the connection with photos before we leave.
Our Gelco Chimney Liner & Rebuild Process

- 1
Call and schedule. A live person answers. We book a Level 2 inspection with camera scan. You get a text when your tech is en route.
- 2
Camera goes in first. Corrine Halstead’s rule: the camera goes in first. Everything else follows from what it finds. We document liner condition, joint integrity, and any obstruction or damage with dated photos.
- 3
Written price, written scope. Before any work starts, you receive a written price, written scope, and written warranty. This is Haven Standard Clause 1. No exceptions.
- 4
Parts decision. We source Gelco OEM when it is available and cost-competitive. When Gelco lead times stretch past three weeks or the OEM part is discontinued, we specify quality aftermarket from our buying network, DuraFlex or HeatShield, and we tell you exactly what we’re substituting and why.
- 5
Repair and test. Liner installation or rebuild proceeds. We pressure-test or smoke-test as appropriate. The work is photographed at completion.
- 6
Documentation and follow-up. You walk away with photos, camera footage, readings, written scope, written warranty, and our 365-Day Done Right Promise stamped on the job. The photo record is archived per Haven Standard Clause 4, a practice we’ve run continuously since 2009.

Why Olympia Homeowners Call Level Two Chimney Olympia for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price before work started and a documented record when it was done. Our technicians are background-checked, uniformed, and licensed, with your tech’s name and license number on the page before they arrive. We know Gelco’s product line because we’ve pulled failed Gelco liners from homes in the Governor Stevens neighborhood, along Boston Harbor Road, and up in the Priest Point Park hills. When Gelco parts are back-ordered, we pivot to DuraFlex or HeatShield through our Haven buying network, keeping your job on schedule without inflating the price. The 365-Day Done Right Promise means if it’s not done right, we make it right. No hassle.
FAQs
No, provided the work meets Gelco’s installation standards and uses listed components. As an independent Gelco service provider, we follow NFPA 211 and manufacturer specs, document with photos, and warranty our workmanship separately under the Haven Standard. Call (360) 464-2015 if you have a specific warranty concern.
Many Gelco components remain available; for discontinued lines we machine equivalent fittings or source compatible aftermarket from DuraFlex or HeatShield. We tell you before ordering, not after. Call (360) 464-2015 to check availability for your model.
The camera decides. A single failed tee or cracked cap is repairable. Multiple seam separations, jacket saturation, or corrosion past 30 percent wall loss means replacement. We show you the footage and explain which category you’re in. Call (360) 464-2015 to schedule the inspection.
Most Gelco liner replacements in Olympia are completed in one day. Full rebuilds with liner replacement typically run two to four days depending on masonry cure times. We book after the camera inspection confirms scope, never before.
A failed liner lets combustion gases, including carbon monoxide, leak into wall cavities or living space. In Olympia’s heating season, that risk runs six months a year. Spalling masonry accelerates with every freeze-thaw cycle. We flag what can wait and what cannot, with photo evidence for each. Call (360) 464-2015 for a free estimate.
