Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

This page is for Fairfax homeowners who own an Olympia Chimney product and want a straight answer about what’s failing, what it costs, and how fast we can fix it. We carry Olympia Chimney caps and crowns but source through our own buying network, so pricing stays where it should be and we’re not leaning on the manufacturer’s retail numbers to set our own.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney builds solid products, but we see the same handful of failure modes across their cap and crown lines in Fairfax weather. Here’s what shows up on camera, why it happens, and what we do about it.
- Rust-through on the Olympia stainless mesh caps - The stainless mesh on Olympia’s spark arrestor caps does a good job keeping burning embers in, but in Fairfax’s freeze-thaw winters the mesh itself becomes the weak point. Water sits in the mesh weave, freezes, and expands the wire until it snaps. We’ve pulled 12-year-old Olympia caps in Mantua where the mesh was rusted clear through while the cap dome still looked new. The fix is straightforward: a new cap with the mesh size matched to the flue, not a universal fit that leaves gaps for bats and birds.
- Crown hairline cracking from thermal cycling - Olympia’s cast concrete crowns are thick and correctly pitched when installed, but Fairfax sees forty-degree temperature swings in a single week. Those swings cause hairline fractures at the flue collar. Water enters, freezes, and the crack widens each season. We repair this with a proper crown coat that flexes with the thermal movement, rather than patching with a rigid material that’ll crack again in two winters.
- Galvanized base flashing corrosion on older Olympia installations - Some Olympia cap installations in Fairfax used galvanized steel flashing that simply isn’t holding up to the acid rain and road salt that makes its way up here from I-66. Once the galvanized layer is gone, the base rusts and lets water into the flue chase. We replace it with either factory-matched stainless or a correctly sealed aftermarket base that’s cut to the flue dimensions, not bent to approximate them.
- Flue collar height mismatches after liner replacement - This one’s specific to Fairfax homes that had their flue liners upgraded in the last decade but kept the original Olympia chimney cap. The new liner, often a DuraFlex stainless liner in this market, sits at a slightly different height than the old clay tile. The Olympia cap no longer seats flush. Water runs down between the liner and the crown. We see this on a lot of the 1970s split-levels in the Fairfax Villa neighborhood. The fix is a correctly sized Olympia cap or a compatible aftermarket cap with the right collar depth to make up the difference.
- Bird and squirrel entry through damaged cap side screens on Olympia’s multi-flue caps - Olympia’s multi-flue cap systems are common on Fairfax’s mid-century colonials with two or three flues side by side. The side screening is securely fastened from the factory, but squirrels chew through the aluminum screening if even a small breach exists. We find nesting material in the smoke chamber more often than homeowners expect. When it happens, we don’t just replace the cap - we camera the flue to document whether nesting material needs to come out.
Our Olympia Chimney Chimney Cap & Crown Process

Here’s exactly how an Olympia Chimney cap or crown job works when you call us in Fairfax.
- 1
You call (571) 443-8256. A live person answers, we ask for the address, and we schedule a time that works. You get a text confirming the appointment and the name of the tech assigned.
- 2
The tech arrives and starts with the camera. We don’t guess. The flue gets scanned, the crown photographed from the roof, and the existing cap removed for inspection. Everything is documented before anything gets priced.
- 3
You see what we see. The tech shows you the photos or video right there on site. If the crown has spalling - surface chipping that means moisture damage - you’ll see it. If the cap mesh is rusted, you’ll see it. Nothing gets recommended without the evidence.
- 4
We write the price. You get a written scope, written price, and written warranty before anything gets ordered. It doesn’t change at the door, per Clause 1 of the Haven Standard. If we’re using aftermarket parts instead of Olympia Chimney OEM because OEM is backordered or overpriced, we tell you that in writing and explain why.
- 5
The work happens. Cap replacement is usually done same visit. Crown repairs or full rebuilds get scheduled once the materials arrive. Either way, the tech is background-checked, uniformed, and the license number is on the paperwork you get.
- 6
The photo record comes back. Every job ends with a documented record of what was done, including after-photos of the installed cap or repaired crown. That’s Clause 4 of the Haven Standard, the same standard we’ve worked to since 2009.

Why Fairfax Homeowners Call Level Two Chimney Fairfax for Olympia Chimney Work

We’ve been doing this long enough to know that most Fairfax homeowners don’t spend their weekends reading chimney cap specs. They want to know three things: what’s actually wrong, how much it costs to fix it, and whether it can wait. Our owner Corrine Halstead built Level Two Chimney Fairfax around answering those three questions with evidence a homeowner can see for themselves. We opened our camera-first documentation practice in 2009 and have inspected or cleaned more than 38,000 chimneys since then, always with a written price before work starts and a documented photo record when it’s done. Every job is backed by the 365-Day Done Right Promise: if it’s not done right, we make it right.
We service Olympia Chimney as an independent provider, which means we’re not bound to the manufacturer’s part pricing or availability. If you need a DuraFlex liner instead of a crown repair, we’ll tell you. If a HeatShield coating is the right call on a flue that’s cracking but still structurally sound, we’ll show you the images and explain why. If Gelco crown coat is what the crack needs, we use it. We work with what the chimney tells us on camera, not with what’s easier to sell. And every call gets answered by a live person, 24/7.
FAQs
No. As long as the replacement cap is correctly sized and installed to the flue’s dimensions, your Olympia Chimney product warranty stays intact. We document every installation with photos so if a claim ever comes up, you have the record. We’re an independent service provider and don’t submit warranty claims on your behalf, but we’ll give you everything you need to file one.
Most stock Olympia Chimney caps are available within 3-5 business days. If we have the flue dimensions and the job doesn’t need a custom size, we can often be back on your roof within the week. Custom caps that need fabrication run 2-3 weeks, and we’ll tell you that timeline in the written quote before you commit to anything.
Yes, if the cracking is surface-level and hasn’t caused the concrete to chip away. We use a flexible crown coat that moves with Fairfax’s freeze-thaw cycles. If the crown is spalling - meaning chunks are breaking off - a full rebuild is the honest answer, and we’ll show you the photos that make the case either way.
We use both. When OEM is the right call for fit, warranty compatibility, or material spec, we order it. When a quality aftermarket cap from our suppliers is a better value and meets the same spec, we tell you in writing and explain why. The decision is always yours and it’s always documented before work starts.
Water keeps getting into the masonry, and each freeze cycle widens the crack. Eventually the crown fails completely and water reaches the flue itself, which is where repair costs climb quickly. In Fairfax’s climate, one season of delay can turn a $300 crown coat into a $1,100 rebuild. Call (571) 443-8256 and we’ll put a camera on it so you can see exactly where yours stands.
