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.

How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney gas fireplace inserts (ODI series) - intermittent ignition failure. The ODI-34 and ODI-42 use a SIT 820 Nova millivolt valve that loses pilot stability above 5,400 feet. Denver’s altitude thins the air mixture; the pilot flame lifts off the thermopile, voltage drops below 325 mV, and the main burner won’t light. We clean the pilot orifice with a #58 drill bit, reset the pilot hood angle to 45 degrees per Olympia’s high-altitude bulletin, and test under load. If the valve body is cracked from thermal cycling, we source OEM or a Robertshaw 7000MVLC with the same 325 mV threshold.
- Olympia Chimney wood-burning fireboxes (OWB series) - refractory panel cracking. The OWB-36 and OWB-42 ship with 1.25-inch refractory cement panels that spall after three to five seasons in Denver’s freeze-thaw cycle. Moisture from snowmelt on the chase cap migrates behind the panels; the cement faces delaminate in sheets. We pull the panels, inspect the steel wrapper for rust-through at the smoke shelf, and install HeatShield Cerfractory foam panels rated to 3,000°F. The camera doesn’t guess. Neither do we - we photograph every crack before quoting replacement.
- Olympia Chimney direct-vent gas units (ODV series) - blocked secondary air intake. The ODV-42’s coaxial vent terminal draws combustion air through an outer annulus that packs with cottonwood seed in May and June across Denver’s Montclair and Park Hill neighborhoods. The flame yellows, soots the glass, and trips the spill switch. We pull the terminal, measure intake vs. exhaust pressure differential with a manometer, and install a Gelco stainless mesh screen if the homeowner’s lot faces mature cottonwoods.
- Olympia Chimney chimney liner systems (OCL flex) - mortar joint gaps at offsets. Olympia’s OCL-316Ti flex liner is a corrugated 316 stainless with a .006-inch wall, excellent for straight flues but prone to accordion compression at 30-degree offsets common in 1920s Denver bungalows near Baker and Berkeley. The corrugations flatten, creosote pools in the valleys, and the liner loses 15% of its cross-sectional area. We camera-map the offset, pull measurements, and replace with DuraFlex 316Ti .012-inch if the offset exceeds 45 degrees - or sleeve with HeatShield Thermocrete if the flue is structurally sound.
- Olympia Chimney top-sealing dampers (OTD series) - cable seizure from creosote glazing. The OTD-2000’s stainless cable runs through a brass guide tube that gums with Class III creosote, a hard, glazed deposit from burning unseasoned pine at altitude. The damper hangs open, bleeding heat. We remove the cable assembly, ultrasonically clean the guide tube, and replace the cable with a Famco silicone-coated strand that resists bonding. If the cast-aluminum frame is warped from chimney fire heat, we quote a Gelco stainless replacement with a lifetime warranty.

Why Denver Homeowners Call Level Two Chimney Denver for Olympia Chimney Work

We’ve worked Olympia Chimney products in Denver since 2009, from the high-efficiency gas inserts in Stapleton rehabs to the wood-burning units in original 1890s brick along Federal Boulevard.

That became the Haven Standard.

Every job has a written price before work starts, a photo record when it’s done, and the 365-Day Done Right Promise stamped on the invoice. Calls are answered by a live person, 24/7.

FAQs
No. As an independent Olympia Chimney service provider, we use OEM or equivalent parts and document every step, which satisfies warranty requirements for routine maintenance. We are not affiliated with or authorized by Olympia Chimney, and we do not perform warranty claims on their behalf. For manufacturer warranty service, contact Olympia directly. For honest repair at market price, call (720) 674-7312.
Common parts - igniters, gaskets, refractory panels - ship to our Denver warehouse in two to three business days. Specialty items like OCL-316Ti liner sections or OTD-2000 cast frames take five to seven days. We stock HeatShield, Gelco, and DuraFlex equivalents that meet or exceed OEM specs and can often complete the job faster. Call (720) 674-7312 to check availability for your model.
Repair if the firebox wrapper is sound, the flue is structurally intact, and parts are available. Replace if the steel body is rusted through, the flue is unlined and shifting, or repair costs exceed 60% of a new unit installed. We give you the camera footage, the written price for each option, and our recommendation - never pressure. Call (720) 674-7312 for a free estimate.
Gas units: annually, before the first fire, to check burner orifices for altitude drift and inspect the vent terminal for debris. Wood units: after every cord burned, or annually if used lightly, due to creosote buildup accelerated by Denver’s cold-start cycles. We document each visit under Clause 4 of the Haven Standard so you have a dated record for insurance or resale. Call (720) 674-7312 to schedule.
Delayed ignition from dirty burners can crack the firebox. A blocked vent terminal risks CO spillage into the living space. These are real hazards, not scare tactics - we show you the camera footage so you see what we see. Most skipped-service units we inspect in Denver show degraded pilot assemblies or cracked refractory that could have been caught early. Call (720) 674-7312 for a free inspection.
