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 handle Olympia Chimney chimney cap and crown work in Ashburn as an independent service provider, not a manufacturer shop. Most cap replacements run $340-$620 installed, while custom multi-flue caps for larger Olympia setups typically land between $700 and $1,100. Crown repair with elastomeric coating generally falls between $450 and $800 depending on damage and flue count. You’ll get a written price before any work starts, and we photograph everything with a camera scan per Haven Standard Clause 4.
This page is for Olympia Chimney owners in Ashburn, Broadlands, Brambleton, and One Loudoun who want to know exactly what’s failing, what it costs, and what documentation they’ll walk away with. Call (240) 220-9412 for a free estimate.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney standard black galvanized caps rust at the base seam within 3-5 years in Ashburn. The winters here cycle through freeze-thaw repeatedly, and the factory seam sits right where water pools after rain. We see rust-through on the skirt and screen sections on older Olympia caps in the Ashburn Farm and Ashburn Village neighborhoods. Our fix is a replacement cap with a stainless steel body, not another galvanized unit, and we reseal the flue tile before mounting.
- Crown spalling on Olympia masonry chimneys is accelerated by the factory mortar wash. Olympia chimney systems built with a standard mortar crown (not precast) absorb water at the crown shoulders, and after a decade of Ashburn weather the concrete starts flaking at the edges. We see this on homes along the W&OD Trail corridor where tree cover holds moisture longer. The repair is crown rebuilding with an elastomeric coating, not just caulk, so water actually sheds.
- Olympia stainless multi-flue caps lose their hold-down brackets in high wind. The factory brackets on some Olympia stainless caps are lighter gauge than we’d like for exposed Ashburn rooflines. In the One Loudoun corridor, where newer construction sits tight and wind gets channeled between homes, we routinely find caps shifted or missing brackets entirely. We replace the cap with heavier-gauge mounting hardware and make sure every leg is through-bolted, not just screwed into mortar.
- Screen mesh on Olympia caps is too wide to keep starlings out of Ashburn flues. Starlings are a real problem in this part of Loudoun County, and Olympia’s standard half-inch mesh lets them through. We’ve pulled live birds and nesting debris out of Olympia flues in BrambletonTownCenter. The fix is a cap with screen mesh sized to exclude starlings, not just keep out leaves.
- Rusted cap screens on Olympia’s lower-cost line trap creosote and become a fire hazard in wood-burning flues. We’ve documented Class III creosote (the thick, tar-like kind that ignites) building up behind the mesh on older Olympia caps on woodstove chimneys. Here’s the thing: cap screens on wood flues need to be checked every sweep, not every few years. We cut the old screen out and install a cap designed for wood-burning systems, then photograph the result.

- 3
We measure the flue and cap footprint, then bring you options. For Olympia chimneys in Ashburn, that usually means a stainless replacement cap from Olympia or an equivalent from Famco or Copperfield. We’ll tell you the trade-offs in plain terms.
- 4
Written price, written scope, written warranty delivered before work starts. No verbal estimates. If you have a competitor’s written quote, bring it. We’ll do a free second opinion.

We do the repair or replacement, then take a final camera pass. You get dated photos of the cap or crown, the flue, and the work done.

FAQs
Most single-flue Olympia cap replacements in Ashburn run $340-$620 installed, and multi-flue custom caps land between $700 and $1,100. The final price depends on your flue size, liner condition, and chimney height. We write the price down before any work starts. Call (240) 220-9412 for an exact quote - it’s free.
We use Olympia parts when they’re the right call, and we also stock quality aftermarket caps from Famco and Copperfield. For Olympia chimneys in Ashburn, the important thing is that the replacement cap fits your flue tile exactly and uses stainless hardware. We’ll show you the options in writing before you decide.
Installing a properly sized cap from a reputable manufacturer does not void your Olympia chimney warranty in most cases. What actually voids warranties is improper installation or using the wrong cap size. We document everything with photos so you have a record should any warranty question come up.
Most crown repairs in Ashburn are completed in a single visit, usually 2 to 4 hours depending on the crown size and whether we’re coating or rebuilding. The elastomeric coating needs time to cure, but you can use your fireplace the same evening. We’ll tell you the exact timeline before we start.
Water gets into the crown cracks, freezes during Ashburn winters, and expands. That’s how small spalling turns into big concrete failures, and the water eventually reaches your liner and smoke chamber. You end up paying for liner work that could have been prevented with a $500 crown repair. If you’re not sure whether yours is at that point, call (240) 220-9412 and we’ll do a camera scan and show you exactly what’s there.
