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 Repair in Ashburn: What to Know First
We provide independent Olympia Chimney chimney repair in Ashburn, and most jobs are completed in a single visit with upfront pricing agreed before we start. Typical repairs run from $280 for targeted mortar repointing to $3,200 for partial rebuilds involving Olympia Chimney components, and we back every job with our 90-Day Done Right Promise in writing. This page is for homeowners who already know they have Olympia Chimney materials in their flue system and want a technician who understands how those specific products age in Loudoun County’s freeze-thaw climate. Call (571) 701-8135 - a live person answers, 24 hours a day.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 316Ti stainless liners: We see these separating at the collar joints in Ashburn’s older Brambleton colonials, especially where the flue gas condenses in shoulder seasons. The 316Ti alloy handles standard wood-burning duty well, but the rolled seam at the flex-to-rigid transition can work loose after 15-20 years of thermal cycling. We reseat with OEM-compatible expansion couplings and back the joint with HeatShield refractory where the thimble shows heat loss.
- Olympia Chimney Pro-Form masonry crowns: These pre-formed concrete crowns shed water adequately when new, but the factory drip edge is shallow and Ashburn’s hard spring rains find the weak spot. Water works behind the crown, freezes by January, and pops the crown off in pieces. We remove the damaged Pro-Form unit, pour a new cast-in-place crown with proper 2-inch overhang and drip kerf, and seal with Gelco crown sealant - not a surface coating, but a breathable membrane that moves with the masonry.
- Olympia Chimney Gelco cap installations on oversized flues: The stock Gelco cap sizes don’t always cover the full flue opening on Ashburn’s 1980s-era Rumford-style fireplaces, leaving a gap that funnels water directly onto the smoke shelf. We measure the actual flue mouth and fabricate a custom Gelco cap with extended skirt and stainless mesh - same brand, properly fitted, so the warranty stays intact and the water stays out.
- Olympia Chimney DuraFlex relining on exterior chimneys: DuraFlex is excellent product, but exterior chimneys in Ashburn’s wind-exposed neighborhoods - think the hills near Belmont Ridge Road - run colder and collect more creosote. The flex liner itself doesn’t fail; the surrounding insulation settles, creating a cold channel that accelerates corrosion at the cleanout tee. We pull and re-insulate with proper DuraFlex ProMix packing, or switch to a rigid DuraFlex liner where the flue run is straight enough to justify it.
- Olympia Chimney parging in pre-fab fireboxes: The factory refractory parging in Olympia’s zero-clearance units cracks at the corner seams after repeated over-firing, which is common in Ashburn where homeowners burn seasoned oak hot and fast. We don’t slop generic refractory over the crack; we rake out to sound material, bridge with HeatShield Cerfractory foam, and finish to factory thickness so the unit retains its UL listing and drafts correctly.
Our Olympia Chimney Chimney Repair Process
- 1
Call and schedule: A live person answers, asks what you’re seeing, and books a Level-2 camera inspection. We don’t guess over the phone.
- 2
Camera inspection and documentation: Our technician runs a 360-degree camera the full flue length, photographs every defect, and explains what you’re seeing in plain English. You get the photos. The flue doesn’t lie - and neither do we.
- 3
Parts decision: If your repair needs Olympia Chimney components, we source OEM or direct-fit aftermarket from our Copperfield and Famco supply chain. We tell you which we’re using and why, with no markup games.
- 4
Upfront pricing and approval: You get one number. That’s the number on the invoice. We don’t start until you approve.
- 5
The repair and live test: Technician completes the work, runs a post-repair camera pass or smoke test, and walks you through what was done.
- 6
Written guarantee and cleanup: We leave the 90-Day Done Right Promise in writing, vacuum the work area, and haul away debris. Most jobs finish in four to six hours.

FAQs
No, provided the repair uses OEM-spec or direct-fit aftermarket parts and follows installation guidelines. As an independent Olympia Chimney service provider, we document every part and procedure so any warranty question can be answered with paperwork, not argument. Call (571) 701-8135 if you have a specific warranty concern.
The camera tells the story. Localized collar separation or a single flex point failure usually repairs well; multiple seam failures, visible corrosion pinholing, or insulation saturation mean replacement is the honest call. We show you the footage and explain which category you’re in before any work is priced. Call for a free camera inspection.
Yes. We stock common Olympia Chimney collars, caps, and DuraFlex fittings on our trucks, and our Copperfield and Famco distributors deliver non-stock items within 24-48 hours to our shop. Most repairs don’t wait on parts. Call (571) 701-8135 to confirm availability for your specific model.
Every year, per NFPA 211, regardless of use frequency. Ashburn’s freeze-thaw cycles stress masonry and metal differently than milder climates, and small cracks in an Olympia Chimney crown or liner collar become expensive problems after one hard winter. Annual camera inspection catches them early. Schedule yours today.
Repointing is grinding out failed mortar and replacing it with new, matched mortar - a structural repair. Tuckpointing is a cosmetic technique using two contrasting mortar colors to simulate fine joint lines, more common on historic brickwork. For Olympia Chimney masonry repairs in Ashburn, we almost always mean repointing: the mortar is failing, and the fix needs to hold, not just look right. Call for an honest assessment of what your chimney actually needs.
