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 Fireplace Services in Olympia: What to Know First
Level Two Chimney Olympia provides independent Gelco fireplace services across Olympia and the South Sound, with most diagnostic appointments scheduled within a week and repair work quoted in writing before any tools come out. A standard Gelco gas fireplace service runs $195-$285; wood-burning fireplace repairs with firebox or damper work typically fall between $340-$720 depending on parts and access. The camera goes in first. Everything else follows from what it finds.
This page is for Olympia homeowners running a Gelco gas fireplace, wood-burning unit, or insert who need service from a technician who knows the difference between a GVF36 vent-free and a GVF42, and who won’t sell you a liner you don’t need. We are not affiliated with or authorized by Gelco - we are an independent Gelco service provider with no dealer obligations pushing replacement over repair.

How Gelco Products Fail - and How We Fix Them
- GVF vent-free series: thermopile voltage drop in damp Olympia winters. The GVF36 and GVF42 units pull combustion air from the room, and the South Sound’s high winter humidity corrodes thermopile contacts faster than drier climates. We see this in homes near Budd Inlet and the Capitol Lake basin where basements run cool and damp. Our fix: clean and test millivolt output, replace with OEM Robertshaw or a verified aftermarket equivalent, and document the reading under Haven Standard Clause 4. If the pilot assembly is scaled from hard water vapor, we descale rather than replace when possible.
- GDIZ direct-vent inserts: failed snap disc or blower thermal switch. The GDIZ series runs a convection blower hard in Olympia’s long heating season (October through April, often longer). The snap disc opens at limit but can fatigue and drift low, causing nuisance shutdowns mid-fire. We test with a calibrated heat gun, replace with the correct L150 or L200 spec, and verify airflow with an anemometer - not a hand wave.
- GVF42 firebox refractory cracking from thermal shock. Olympia’s temperature swings - 35°F at dawn, 55°F by afternoon in shoulder season - stress the GVF42’s refractory panels when the unit cycles on cold metal. Hairline cracks under 1/8 inch we monitor; through-cracks we replace with Gelco-pattern panels sourced through our Haven buying network. We photograph before and after under Clause 4.
- GDV series direct-vent: blocked termination cap from Douglas fir needle drop. The GDV’s horizontal termination sits low on many Olympia ranches and draws in needles from the big firs in neighborhoods like Priest Point and Eastside. Restricted exhaust trips the pressure switch. We pull the cap, measure draft with a manometer, and clear the flue path. If the pressure switch has cycled too many times, we replace it - the diaphragm fatigues.
- Gelco wood-burning fireplaces: smoke chamber and damper corrosion from Pacific Northwest moisture. Gelco’s wood units in Olympia homes often show throat damper rust where the firebox meets the flue, especially in homes built 2015-2020 with tighter envelopes and less natural draft. We inspect with a chimney camera, measure the smoke chamber slope, and repair or replace the damper assembly. If the smoke chamber needs parging, we quote HeatShield as an alternative to a full rebuild.
Our Gelco Fireplace Services Process

- 1
Call and schedule. A live person answers (360) 464-2015. We ask the model number if you have it, the symptom, and the address. You get a window and a text when the tech is en route.
- 2
Camera-scan inspection. NFPA 211 Level 2: camera down the flue, photos of the firebox, damper, and termination. For gas units, we test gas pressure, millivolt output, and safety switch function. Everything is recorded before we touch a wrench.
- 3
Written price, written scope. We deliver a written price and written scope before work starts - Haven Standard Clause 1, no exceptions. If parts are needed, we note OEM Gelco versus quality aftermarket (Robertshaw, White-Rodgers, DuraFlex venting) and explain the trade-off.
- 4
Repair with documented steps. The tech performs the work, photographing critical steps: the old part, the new part’s part number, the test reading. Corrine Halstead trains our crew to write findings before writing the invoice.
- 5
Final test and photo record. Gas units: combustion analysis, spillage test, and draft measurement. Wood units: draw test and visual confirmation. The completed photo record uploads to your job file under Haven Standard Clause 4.
- 6
Written warranty and 365-Day Done Right Promise. You get a written warranty and our promise: if it’s not done right, we make it right. The invoice, photos, and warranty are yours to keep for insurance or resale.

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 done. That archive practice became Clause 4 of the Haven Standard.
For Gelco owners in Olympia, the difference is specific: our techs carry the common GVF thermopile, GDV pressure switch, and refractory panel patterns on the truck, so most repairs finish in one visit. If your Gelco part is back-ordered, we have qualified cross-references from DuraFlex and HeatShield that we know work - no guessing, no waiting two weeks for a factory box. Background-checked, uniformed technicians. License number on the page. A named tech assigned to your job, not a rotating subcontractor.
And our Free Second Opinion on Any Written Estimate means you can bring us a competitor’s quote and we’ll tell you straight if the scope matches what we see on camera.
FAQs
No. As an independent Gelco service provider with no manufacturer affiliation, our work does not void your factory warranty provided we use OEM or equivalent-spec parts and document the service. We keep part numbers and test readings in your photo record for any warranty claim you file directly with Gelco. If warranty coverage is critical to your situation, call (360) 464-2015 and we’ll review the specific part and labor coverage before we start.
Common GVF and GDV parts - thermopiles, blowers, snap discs - we stock on our Olympia warehouse shelf and install same visit. Refractory panels and specialized venting ship from Gelco’s regional distributor in 3-5 business days. If your heat is out and the part is back-ordered, we quote a verified aftermarket equivalent with equivalent specs and warranty, and we don’t proceed without your written approval. Call (360) 464-2015 for current availability on your model.
Repair if the firebox is sound, the venting meets current code, and the repair cost is under 40% of replacement. Replace if the unit is pre-2010, parts are obsolete, or the venting is unlined masonry that would need full relining to meet today’s standards. We make this recommendation only after camera inspection and show you the photos. Our written estimate includes both repair and replacement options when both are viable. Call (360) 464-2015 for a free camera inspection.
Annually, before the first fire of the season. Olympia’s damp winters and the long off-season (May through September) let moisture accumulate in burner ports and pilot assemblies. An annual service checks gas pressure, combustion, and venting integrity. Skipping it risks carbon monoxide spillage from incomplete combustion or a blocked termination. We book sweeps starting in August for homeowners who want the pre-season slot. Call (360) 464-2015 to schedule.
Class I creosote becomes Class III glazed creosote, which is flammable and cannot be removed with standard brushes. In Olympia’s cool, wet climate, creosote builds faster than in drier regions because wood burns cooler and incomplete combustion is more common. A chimney fire can reach 2,000°F and crack the flue liner, opening paths to framing. We find this damage with our camera and show you before quoting repair. The sweep itself is preventive and far cheaper than rebuilding after a fire. Call (360) 464-2015 for an exact quote - estimates are free.
