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 Sterling: What to Know First
Olympia Chimney cap and crown work in Sterling runs $220-$480 for a standard cap replacement and $700-$1,400 for a full crown rebuild, and we finish most jobs in a single visit. We’re an independent Olympia Chimney service provider, not a manufacturer rep, which means we tell you what’s actually wrong without a sales script behind it. If you own an Olympia flue system in Sterling and the cap or crown has been patched, rusted, or missing for a while, this page tells you what you’re dealing with and what it costs to fix right. Call (571) 518-5470 and Wendell himself may pick up.
How Olympia Chimney Products Fail - and How We Fix Them
We’ve been on enough Sterling roofs to see patterns. Olympia Chimney builds solid stainless flue systems, but the cap and crown are the first parts to go because they take every bit of weather the Mid-Atlantic throws at them. Here’s what we find, series by series:
- Champion Cap rust-through at the base ring. The Olympia Champion line uses a galvanized base ring on many caps sold before 2015, and once that ring sits in pooled water for a few seasons, it rusts through at the bolt holes. The screen may look fine while the cap is actually loose and lifting at one corner. We replace the whole assembly with a stainless ring rather than patching it, because a patched base ring fails again inside two years.
- Ventis CPF crown spalling from trapped water. We see crowns on Ventis and CPF systems in Sterling break down faster when the drip edge wasn’t cut properly at install. The crown doesn’t shed water far enough away from the flue tile, so it soaks in, freezes in January, and spalls off in sheets come March. Our crown rebuild includes a proper overhang and drip kerf, which is the difference between a five-year patch and a twenty-year crown.
- Multi-flue cap fitment on mixed-height flues. Olympia’s multi-flue caps assume the flue tiles sit at the same height. On older Sterling colonials with a clay tile that’s shifted or a short tile next to a tall one, the cap sits cocked and leaves a gap at one end. We build a custom stainless skirt or level the tile surface before we set the cap, so you don’t get rain driving sideways into the flue.
- Screen clogging on the Legacy line. The Legacy series screens are fine mesh, which is good for ember control but bad when a Sterling oak drops its pollen in spring and the screen cakes over. Draft drops, smoke rolls back, and the homeowner thinks the flue liner is shot when it’s actually just a clogged cap screen. We’ll show you the photo before we touch it, and often the fix is a cleaning, not a replacement.
- Cracked crowns from standard mud mix. A lot of the older Olympia installs in Sterling got crowns poured from plain mortar, not a proper crown mix. Mortar can’t handle the thermal expansion of a stainless flue cycling hot to cold, so hairline cracks show up fast and widen every year. We rebuild them with a fiber-reinforced crown compound that moves with the flue instead of fighting it.
Our Olympia Chimney Chimney Cap & Crown Process
We don’t do mystery pricing or surprise add-ons. Here’s how a typical Olympia cap and crown job goes from the first call to the walkthrough:
- 1
Call and schedule. A live person answers at (571) 518-5470. We’ll ask which Olympia system you have and what you’re seeing from the ground. Then we book a real arrival window.
- 2
Roof inspection with camera. Wendell or one of his crew gets on the roof, pulls the cap if needed, and runs a camera down the flue. You see the footage. We tell you plainly what’s bad and what can wait.
- 3
Parts decision, stated out loud. If an OEM Olympia cap is the right call and still available, we use it. If an OEM part is backordered or the price is out of line with what a quality stainless aftermarket cap delivers, we say so and let you decide. Either way, the price is set before we start.
- 4
Cap replacement or crown rebuild. Cap work usually takes under an hour. A crown rebuild means stripping the old crown, prepping the surface, pouring the new compound, and cutting a proper drip edge. We do it the same day in most cases.
- 5
Water and draft test. We run a water test to confirm the cap sheds properly and check draft at the firebox before we come down off the roof.
- 6
Cleanup and the 90-Day Done Right Promise. We clean up like we were never there, then we hand you the written guarantee. If it’s not right, one call brings us back.

FAQs
No, not when the cap is installed correctly with compatible materials. As an independent Olympia Chimney service provider, we don’t do anything that would jeopardize a valid warranty, and we’ll tell you if a specific part choice could. Bring us the warranty papers and we’ll work within them.
Most stainless Olympia caps last 8-12 years in Sterling’s weather, but the base ring and screen usually fail before the dome. We see Champion-series caps from the early 2010s starting to rust at the ring now, so if yours is around that age, it’s worth a look. Call (571) 518-5470 for a free roof inspection.
We can usually match it. If the exact model is still in production, we order it. If it’s been discontinued, we can fabricate a stainless cap that matches the footprint and look, often for the same or less than the OEM list price.
Have it looked at once a year, burn or no burn. Small crown cracks don’t announce themselves, but every Sterling winter freeze-thaw cycle widens them. A $350 recoat now beats a $1,200 rebuild in three years.
Most cap replacements are done within three to five days of the call, and crown work is usually scheduled within a week. We don’t promise same-day because we don’t work against a clock that makes us sloppy. Call (571) 518-5470 and we’ll give you a real arrival window and call if it slips.
