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 Cap & Crown in Ashburn: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Ashburn, with most inspections booked within a few days and repairs completed in a single visit when possible. A standard Olympia Chimney cap installation runs $340-$620, while crown repair or coating typically falls between $280-$550, depending on flue count and access. We do not quote over the phone for crown work; every job starts with a Level-2 camera inspection so you see what we see.
This page is for homeowners in Ashburn who have an Olympia Chimney stainless steel liner, cap, or crown component and need straight talk about whether it can be repaired, what parts fit, and what it will cost. If you are unsure of your model, we will identify it on arrival. Call (571) 701-8135 and a live person will answer, any hour.
How Olympia Chimney Products Fail - and How We Fix Them
- ProFlex 316Ti liner caps loosen at the draw band after five to seven winters. Ashburn’s freeze-thaw cycles work the metal at the flue top, and the factory draw band can back off. We find this often in the older colonials near One Loudoun where the flue runs straight up through an uninsulated chase. We replace the band with a heavier-gauge stainless clamp and add a wind-resistant cap if the original is missing its storm collar.
- ProFlex 304 caps corrode at the mesh screen weld points. The 304-grade mesh is adequate inland, but Loudoun County’s humidity and occasional ice accumulation accelerate rust at the corners. We spot-weld or replace with 316-grade mesh, which we stock because it outlasts the original in this climate.
- Olympia Chimney multi-flue caps sag on wide masonry crowns. The 13×17 and 17×21 models span a lot of open mortar, and without proper footing blocks the cap settles toward the center. We shim with stainless spacers and repoint the crown edges before setting the new cap so the load distributes evenly.
- Factory crown wash on Olympia Chimney chase covers cracks within four years. The thin factory cement layer over galvanized steel cannot flex with thermal expansion. We grind back to sound metal, apply a bonding primer, and trowel on a polymer-modified crown coat at proper thickness. This is not a slop-on job; we measure it.
- Olympia Chimney’s standard single-flue cap can admit blowing rain on east-facing flues. Ashburn’s spring storms track northeast, and a low-profile cap without a skirt directs water onto the smoke shelf. We upgrade to a Gelco high-elevation cap with a deeper overhang, or fabricate a skirt extension if the homeowner wants to keep the Olympia Chimney branding visible.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, notes your Olympia Chimney components if you know them, and books a Level-2 inspection. We do not guess at prices beforehand.
- 2
Camera inspection and documentation. Our technician runs a chimney camera from the firebox to the crown, photographing the cap, crown surface, flue edges, and any deterioration. You receive the photos and a plain-English verdict before any work is proposed.
- 3
Parts decision: OEM or quality aftermarket. If your cap is under warranty, we use Olympia Chimney OEM parts to preserve coverage. If the warranty has expired, we may recommend Gelco or Copperfield equivalents that match or exceed factory specs, often at lower cost. We explain the trade-off and let you decide.
- 4
Repair or replacement. For crown work, we grind, prime, and coat to manufacturer-specified thickness. For cap replacement, we verify proper draw band torque and storm collar seal. Multi-flue caps get footing blocks and shimming as needed.
- 5
Post-repair verification. We run the camera again to confirm no debris fell during work, verify draft with a smoke pencil, and check that the new cap does not obstruct adjacent flues.
- 6
Cleanup, written guarantee, and payment. The technician hauls away old material. You receive a written invoice with the 90-Day Done Right Promise noted, and pay the number you were quoted. No surprises.

Why Ashburn Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We are an independent Olympia Chimney service provider, not a factory affiliate. That means we choose the part that fits your situation, not the part that moves inventory.
Our technicians carry Olympia Chimney, Gelco, and Copperfield caps on the truck, plus DuraFlex and HeatShield materials for liner and crown work that extends beyond the cap. Most jobs finish in one visit because we do not make two trips for parts.
The 90-Day Done Right Promise covers every repair. If the cap leaks or the crown coating cracks, we come back. In writing, no arguing. Russell Haines has been reading flues across Ashburn for well over a decade, from the mature neighborhoods near One Loudoun to new construction along Loudoun County Parkway. The flue doesn’t lie - and neither do we.
A live person answers our phone 24 hours a day. Background-checked, uniformed technicians. The price on the estimate is the price on the invoice.
FAQs
No, if the work is done with OEM parts and proper installation. As an independent Olympia Chimney service provider, we use factory-spec components when your warranty is still active, and we document the installation so you have a record. If the warranty has expired, we will show you equivalent or upgraded aftermarket options. Call (571) 701-8135 to check your warranty status.
The camera tells the story. If the cap mesh is intact and seated firmly, but water is entering the flue, the crown is likely the culprit. If the cap is rusted, loose, or missing its storm collar, the cap needs replacement and the crown may need attention too. We do not recommend both unless the inspection shows both are failing.
We stock common Olympia Chimney cap sizes and draw bands, and our suppliers in northern Virginia carry most ProFlex and standard cap lines with two-day availability. For discontinued models, we fabricate or source compatible equivalents from Gelco or Copperfield that match the spec.
A properly applied polymer-modified crown coating lasts 10-15 years in Ashburn’s climate; a full rebuild with proper overhang and drip edge lasts 20-30 years. We recommend coating when the crown is structurally sound but surface-cracked, and rebuild only when the crown has lost more than 25% of its mass or the steel chase cover beneath is failing.
For the initial inspection, yes, so we can show you the camera footage and discuss options. For the repair itself, you do not need to be present if you have arranged access and payment, though we prefer a homeowner available at completion to review the work. Most repairs take two to four hours.
