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.
Olympia Chimney Chimney Liner & Rebuild in Ashburn: What to Know First
We provide independent Olympia Chimney chimney liner and rebuild service in Ashburn, with most liner replacements and partial rebuilds completed in a single visit and priced upfront before any work begins. A typical Olympia Chimney stainless steel liner installation in this market runs between $2,800 and $4,500, while partial rebuilds start around $1,800 and full rebuilds range from $6,500 to $12,000 depending on height and access. This page is for Ashburn homeowners who own an Olympia Chimney product and have been told they need liner work or masonry repair - or who suspect it after seeing water stains, smelling smoke indoors, or hearing their sweep mention “spalling” or “safety hazard” without showing them why. We’re Hearthstone Chimney Co., and we’ve been working on chimneys in Loudoun County for over 42 years. Call (571) 701-8135 when you’re ready for a second opinion you can see for yourself.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney ProFlex series: creosote buildup at flex joints. The ProFlex flexible liner’s corrugation pattern traps more creosote than smooth-wall alternatives, especially in Ashburn’s cold-start shoulder seasons when homeowners fire the insert at low temperatures for hours. We pull the liner, inspect every corrugation valley with a camera, and either mechanically clean to bare metal or recommend replacement with a smooth-wall DuraFlex equivalent if the wall thickness has degraded below 0.006″.
- Olympia Chimney rigid stainless: thermal fatigue at the tee connection. The rigid 304-grade tee assemblies on older Olympia Chimney systems develop circumferential cracking where the horizontal snout meets the vertical riser, usually after 12-18 years of Ashburn’s freeze-thaw cycling. We cut back to sound metal, fabricate a custom transition piece when needed, and back every welded joint with a camera inspection before we sign off.
- Olympia Chimney aluminized steel liners: premature oxidation in condensing conditions. These economy-grade liners were sold heavily in the mid-2000s and fail fast when paired with modern EPA-certified stoves that run cooler flue gas. The aluminized coating sacrifices itself from the inside out, leaving pinholes we spot during Level-2 inspection. We replace with 316Ti stainless from Olympia Chimney’s current catalog or upgrade to DuraFlex Pro if the application warrants.
- Olympia Chimney top-mount dampers: liner displacement after cable failure. The integrated damper/cap combos on Olympia Chimney systems use a stainless cable that can fray and snap, letting the damper plate drop and knock the liner off its collar. We see this most in Ashburn’s wind-exposed neighborhoods like Belmont Ridge and Ashburn Farm. The fix is a new damper assembly plus re-anchoring the liner with a proper top plate - not just a cap swap.
- Olympia Chimney masonry surround: water intrusion behind the chase cover. Even when the liner itself is sound, Olympia Chimney’s factory chase covers can pool water at the corners if the original installer didn’t pitch the pan correctly. In Ashburn’s clay-heavy soils, that water wicks into the chase and degrades the liner support system from the outside. We rebuild the chase crown with proper slope, install a Gelco or Famco cover with drip edges, and only then address liner condition - doing it in reverse order is throwing good money after bad.
Our Olympia Chimney Chimney Liner & Rebuild Process
- 1
Call and schedule. A live person answers, 24 hours a day. We book a two-hour window and send a confirmation text with the technician’s name and photo.
- 2
Level-2 camera inspection. We run a camera the full length of your Olympia Chimney flue, photograph every joint, every offset, and any damage. You watch the screen with us. Russell Haines reviews the footage the same evening if the crew flags anything unusual.
- 3
Plain-English verdict and upfront price. We explain what’s wrong, what happens if you wait, and what it costs to fix it right. The number on the estimate is the number on the invoice. No surprises.
- 4
Parts decision: OEM or quality aftermarket. For Olympia Chimney systems, we source direct-fit Olympia components when they make sense - but we’ll tell you when a DuraFlex, HeatShield, or Gelco equivalent performs better for less, or when the original design has a known weakness we’d rather engineer around. As an independent Olympia Chimney service provider, we have no obligation to push OEM parts that don’t serve your situation.
- 5
The repair and live test. Crews arrive uniformed, background-checked, and equipped for most jobs in one visit. After liner installation or rebuild, we run a smoke test and final camera pass to verify draft and integrity.
- 6
Documentation and guarantee. You get photos, a written report, and our 90-Day Done Right Promise in writing. If it’s not right, we make it right. No paperwork to dig up, no arguing.

Why Ashburn Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been sweeping and rebuilding chimneys in Ashburn since before One Loudoun was anything but farmland, and we’ve learned that the flue doesn’t lie - and neither do we. Our crews know Olympia Chimney products specifically: the ProFlex creosote pattern, the rigid tee fatigue zone, the aluminized liner failure timeline. When an Olympia part is the right part, we use it. When a DuraFlex, HeatShield, or Gelco solution outperforms it, we say so plainly and show you why.
The 90-Day Done Right Promise means if we miss something, we come back. In writing, no arguing. Background-checked, uniformed technicians. Most jobs done in one visit. A live person on the phone, every hour of every day. That’s the Keystone Standard - Krafted right, Every time, Your home first, Standing behind it.
FAQs
No - as an independent Olympia Chimney service provider, we follow manufacturer installation specs and use OEM or equivalent parts that maintain warranty coverage where applicable. We document everything with photos so you have a record if questions arise later. Call (571) 701-8135 if you’d like us to review your specific warranty terms before we start.
Most single-flue flexible liner replacements are completed in four to six hours from arrival to cleanup. Rigid liners or jobs with difficult roof access - common in the older two-story colonials near Ashburn Village - may take a full day. We tell you which yours is before we book.
We stock common Olympia Chimney liner diameters, top plates, and termination caps at our Loudoun warehouse. For specialty sizes or discontinued series, we cross-reference DuraFlex and Gelco equivalents that meet or exceed OEM specs. We’ll never leave you waiting two weeks for a part we can source faster.
We make that call with the camera, not a guess. Isolated damage - a failed collar, a single offset crack, minor pitting - often qualifies for repair with HeatShield cerfractory sealant or a welded patch. Widesde thinning, multiple perforations, or any separation in a combustible wall means replacement. You’ll see the difference on screen before we quote either option.
A compromised liner lets heat, sparks, and carbon monoxide reach combustible framing. In Ashburn’s tight construction, that risk is real and specific. But we’re not going to invent a deadline that doesn’t exist - we’ll show you what we found, explain the hazard in plain terms, and tell you honestly if the situation allows you to plan the work for next season. Call (571) 701-8135 and we’ll walk through your footage together.
