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 Repair in Olympia: What to Know First
We provide independent Gelco chimney repair in Olympia, from mortar repointing to full rebuilds, with a written price before any work starts and a camera-scan inspection included on every call. Most Gelco repairs we book run $380 to $2,800 depending on whether we’re sealing a crown or rebuilding a spalled upper stack, and we typically schedule within a week during the off-season, two to three weeks once burning season starts in October.
This page is for Olympia homeowners who already know they’ve got Gelco components in their chimney system and need someone who can name the part, source it honestly, and document what was done. If that’s you, call (360) 464-2015 for a free estimate. We’ll send a written quote before anyone picks up a trowel.
How Gelco Products Fail - and How We Fix Them
- Gelco Multi-Flue Caps (Model M-8 through M-14 series) - The 304 stainless mesh on these caps degrades faster in Olympia’s marine air than inland specs suggest. We see rust-through at the weld seams around year seven, not the advertised fifteen. Our fix: pull the cap, assess the flue wall condition underneath, and replace with either OEM Gelco mesh or a heavier 316-grade aftermarket equivalent sourced through our Haven buying network. We document the flue wall with photos before the new cap goes on.
- Gelco Pre-Fab Chase Covers (aluminum and galvanized lines) - These covers pond water at the center seam where the chase meets the roofline, especially on low-slope installations common in the Tanglewilde and Indian Creek subdivisions. The galvanized line rusts from the underside first; by the time you see staining on the ceiling, the plywood chase is soft. We replace with a Gelco-compatible stainless chase cover, add a cricket if the roof pitch demands it, and photo-document the chase interior for the record.
- Gelco Single-Flue Caps with integral dampers (SD series) - The cast-aluminum damper frame cracks where the control arm meets the throat plate. Owners notice smoke backup on cold starts or a damper that won’t fully close. We remove the cap, inspect the flue liner for creosote buildup that may have contributed to the binding, and either rebuild the damper mechanism with OEM Gelco parts or retrofit a Lock-Top damper if the frame is too far gone. The camera goes in first. Everything else follows from what it finds.
- Gelco chimney pots and decorative shrouds (Terra Cotta and metal lines) - The terra cotta pots absorb water through hairline cracks, then spall in freeze-thaw cycles. Olympia doesn’t get the hard freezes of Corrine’s Queens days, but thirty-plus nights below freezing each winter is enough. We remove the pot, inspect the flue termination for liner damage from falling spalls, and either reseat a sound pot with a proper flue seal or replace with a Gelco metal shroud that sheds water instead of absorbing it.
- Gelco stainless flue liners (UL-listed 316Ti and 304 variants) - The 304 variant, common in budget installations from 2010 to 2018, develops pinpoint corrosion at the flex joints where condensation pools. In Olympia’s wet shoulder seasons, that condensation is nearly constant from October through May. We camera-scan the full liner length, mark the corrosion points, and replace with 316Ti or a DuraFlex equivalent if the damage is localized, or pull and reline if it’s systemic. We never patch a liner without showing the owner the camera footage.
Our Gelco Chimney Repair Process

- 1
Call and schedule. A live person answers, 24 hours a day. We book a two-hour arrival window and text when the tech is en route.
- 2
NFPA 211 Level 2 inspection. Camera down the flue, photos of the exterior, readings of the clearances. The tech names what they see in plain terms - spalling, delamination, creosote class, liner condition.
- 3
Written price and scope. Before any work starts, you get a written price, written scope, and written warranty under Haven Standard Clause 1. No exceptions. If you have a competitor’s written estimate, we’ll give you a free second opinion.
- 4
Parts decision. We source Gelco OEM when it makes sense for warranty continuity, but we’re not beholden to it. Our Haven buying network also stocks DuraFlex liners, HeatShield cerfractory mix, and Olympia Chimney components. We explain the trade-off and let you decide.
- 5
The repair and post-work test. We complete the repair, run a smoke test or camera verification, and clean the work area. Background-checked, uniformed techs; license number on the invoice.
- 6
Documented record and guarantee. You receive photos, camera footage, and a written completion report under Haven Standard Clause 4. The 365-Day Done Right Promise applies from that date. If it’s not done right, we make it right.

Why Olympia Homeowners Call Level Two Chimney Olympia for Gelco Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a significant share of those runs involved Gelco caps, liners, and chase covers in Olympia’s mix of 1970s ranches and newer builds. Corrine Halstead and her crew know which Gelco series were spec’d by which local builders, what fails first in marine climates, and where to source parts without marking them up through three middlemen.
We’re independently owned and operated, not a franchise, and we work to the Haven Standard we helped develop. That means background-checked techs, a text when yours is on the way, and a photo record you can show your insurer or home buyer. We also service DuraFlex and HeatShield systems, so if your Gelco repair reveals a deeper liner issue, we don’t hand you off to another contractor.
The 365-Day Done Right Promise is stamped on every job. If we repointed your crown and it cracks, we come back. No argument, no invoice.
FAQs
No, provided the repair uses Gelco OEM parts or equivalent-rated components installed to UL standards. As an independent Gelco service provider, we document part numbers and installation methods so any future warranty claim has a paper trail. Call (360) 464-2015 if you need help verifying your original install date.
Most cap replacements and chase cover installs finish in two to four hours. Repointing runs one to two days depending on scaffold setup and cure time. We give you a written schedule with the price, not a guess after we arrive.
We stock common Gelco caps, mesh, and chase cover sizes through our Haven buying network. For discontinued lines, we source compatible aftermarket parts from Olympia Chimney or Famco and show you the spec sheet before installation. You don’t need to hunt parts.
The camera decides. If the flue liner is sound, the footing is stable, and the damage is cosmetic or localized, repair is the honest call. If we find liner separation, structural settlement, or widespread spalling below the roofline, we’ll show you the footage and quote both options. Nothing is recommended without camera evidence you can see. Call (360) 464-2015 for a free inspection.
Deferred maintenance on a Gelco cap or chase cover leads to water intrusion, which leads to liner corrosion, ceiling damage, and in worst cases, a chimney fire from creosote buildup in a compromised flue. Olympia’s wet winters accelerate every stage. The repair cost at year three is roughly triple what it would have been at year one. Call (360) 464-2015 for an exact quote - estimates are free.
