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): The pilot assembly on early ODI units tends to soot up faster than comparable HeatShield-lined inserts because the burner orifice sits lower in the firebox, drawing more lint from the room. We pull the burner, clean the orifice with a numbered drill set (not a wire brush, which enlarges the hole), and test gas pressure at the manifold. If the thermopile is below 325 mV under load, we replace it with an OEM SIT valve assembly - aftermarket copies fail within two seasons in Manassas’s hard-water environment.
- Olympia Chimney wood-burning fireplaces (OWB line): The refractory panels in OWB-36 and OWB-42 units crack diagonally from the lintel down after 8-12 years of thermal cycling. This is normal wear, not an emergency. We measure crack width with a feeler gauge - anything under 1/8 inch gets monitored; over that, we install new 1-inch refractory panels rated to 2,100°F, sourced through Copperfield supply, and seal the joints with Rutland refractory cement.
- Olympia Chimney top-sealing dampers (OTD series): The stainless cable on OTD dampers frays where it exits the chimney cap, especially on south-facing exposures in Manassas where UV and temperature swings are hardest. We replace the cable with a Gelco stainless aircraft cable (7×19 construction for flexibility) and lubricate the pivot pin with copper-based anti-seize - not WD-40, which gums up in cold weather.
- Olympia Chimney firebox throat dampers (legacy cast-iron): The cast-iron frame warps over decades, letting conditioned air escape up the flue year-round. On homes near the Manassas National Battlefield Park, we see this constantly in 1960s and 1970s builds where the original Olympia damper was never maintained. We measure the gap with a flashlight test from below - if light shows around the perimeter, we either re-seat the frame with furnace cement or recommend a lock-top damper installation if the frame is too far gone.
- Olympia Chimney vented gas log sets (OGL series): The silica sand in OGL burners migrates toward the rear, causing flame impingement on the back wall and sooting the logs. Homeowners often replace the whole set when the fix is simpler: we redistribute the sand to the specified depth (usually 1/2 inch), verify burner port alignment, and replace any cracked ember material. The logs themselves rarely fail - the burner geometry does.
Our Olympia Chimney Fireplace Services Process
- 1
Call intake: A live person answers, notes your Olympia Chimney model if you know it, and schedules a visit. We do not quote blind over the phone - we need eyes on the unit.
- 2
Level-2 camera inspection: Our technician runs a chimney camera from the firebox to the cap, documenting every joint, liner section, and damper condition. You get the photos and a plain-English verdict before any work is proposed.
- 3
Parts decision: For Olympia Chimney components still in production, we source OEM when it makes sense. For discontinued lines - the pre-2010 ODI inserts, for example - we use professional-grade aftermarket from DuraFlex or Gelco that meets or exceeds OEM spec, and we tell you which we’re using and why.
- 4
The repair: Our background-checked, uniformed technician completes the work with the agreed materials. Most Olympia Chimney fireplace repairs finish in one visit because we stock common failure parts on the truck.
- 5
Testing and documentation: Gas units get a full combustion analysis; wood units get a draft test. We photograph the completed work and record model numbers and part sources in your file.
- 6
The guarantee: Every job is covered by our 90-Day Done Right Promise in writing - if it’s not right, we come back. No paperwork to dig up, no arguing.

FAQs
No - your product warranty covers manufacturing defects, not who performs maintenance. However, warranty claims for defective parts still go through Olympia Chimney directly; we document our work with photos and part numbers so you have evidence if a claim arises. Call (571) 586-0593 if you need help navigating a warranty submission.
Current-production parts (ODI-42 inserts, OTD dampers) typically arrive in 3-5 business days from regional distribution. Discontinued lines require us to source compatible aftermarket from DuraFlex or Gelco, which we stock for common failures - often same-day completion. We tell you which situation applies before you book.
Replace when the firebox is cracked through to the outer shell, the liner is deteriorated beyond relining, or repair costs exceed 60% of a new unit installed. We make this call with camera evidence you can see, not a sales pitch. Many 15-year-old Olympia units need $400 in damper and refractory work and run safely for another decade. Call for a free second opinion if another company recommended replacement.
We schedule within a few days for standard service and prioritize calls involving carbon monoxide risk or gas odor. Our technician arrives in a marked truck, in uniform, with the common Olympia Chimney failure parts already on board. Most repairs finish in one visit. Call (571) 586-0593 - a live person answers now.
Delayed maintenance leads to sooted burners, failed thermocouples, and eventually heat exchanger damage that turns a $200 tune-up into a $1,200+ repair. In Manassas, where many homes run gas fireplaces as primary heat sources through January and February, the wear accumulates faster than in milder climates. We recommend annual inspection before burning season - call for our $89 Seasonal Tune-Up.
