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 inserts, especially in Ashburn’s hard water zone where mineral residue affects gas orifices. We pull the burner, clean the pilot orifice with the right gauge wire, and test flame color against the Olympia spec sheet. If the thermopile is dropping millivolts, we replace it with an OEM part or a cross-referenced Famco equivalent that matches the original rating exactly.
- Olympia Chimney wood-burning fireplaces (OWB builder series): The refractory panels in the OWB line are thinner than DuraFlex’s comparable units and crack diagonally from thermal shock, usually after five to seven seasons of Ashburn’s freeze-thaw cycles. We document the cracks with camera photos, show the homeowner, and install HeatShield refractory replacement panels rated for higher thermal shock. The flue doesn’t lie - and neither do we.
- Olympia Chimney top-sealing dampers (OTD series): The stainless cable on OTD dampers frays where it exits the chimney cap, especially on Ashburn homes with mature oak canopy that drops acidic leaf tannins onto the hardware. We replace the cable with a Gelco stainless assembly that has a heavier sheath at the wear point, then seal the penetration with Copperfield high-temp silicone.
- Olympia Chimney firebox throat dampers (legacy cast-iron): These warp from the center after a decade of over-firing, a pattern we see repeatedly in the older colonials near One Loudoun where homeowners burn seasoned oak hot and fast. We measure the warp with a straightedge, photograph it, and either machine the seat flat or replace with a stainless pivot damper from Gelco that won’t repeat the problem.
- Olympia Chimney direct-vent gas units (ODV series): The termination cap on ODV units clogs with lint and pollen in Ashburn’s spring, causing pressure switch failures that read as “bad board” on a basic diagnostic. We clean the termination first, test actual manifold pressure with a digital manometer, and only replace the board if the pressure proves correct. This saves homeowners from a $400 part they didn’t need.

FAQs
No. Routine maintenance by an independent service provider does not void your warranty, though we document everything in case you need to file a claim later. We use OEM or spec-matching parts and record part numbers. If you have a current warranty question, call us at (571) 701-8135 and we’ll walk through your coverage before we book.
Common wear parts - thermopiles, pilot assemblies, refractory panels - we stock or can source within two to three business days through our Famco and Gelco distributors. Older Olympia series may take five to seven days. We won’t start a job we can’t finish promptly.
Most Olympia units built after 2005 are worth repairing if the firebox structure is sound. We replace when repair costs exceed 60% of a comparable new unit, or when the flue is compromised beyond liner repair. Our camera inspection shows you the condition; you decide. Call (571) 701-8135 for a free look.
Annually, before the first fire of the season. Gas units accumulate dust and debris that affect combustion, and Ashburn’s pollen load clogs termination caps faster than inland climates. Skipping service risks carbon monoxide spillage from incomplete combustion. Book your $89 Seasonal Tune-Up by calling (571) 701-8135.
Creosote builds in the flue, increasing chimney fire risk and restricting draft. In Ashburn’s humid summers, that creosote absorbs moisture and accelerates liner corrosion. We find stage-three glazed creosote in units that haven’t been swept in three years. A sweep costs far less than a rebuild. Schedule yours at (571) 701-8135.
