Olympia Chimney Chimney Cap Installation Nationwide

Olympia Chimney Chimney Cap Installation: The Bedford Owner’s Guide

We stock and install Olympia Chimney-compatible chimney caps for most residential flue sizes found in Bedford, with typical installed pricing running $285-$475 depending on cap style and whether your flue needs a custom adapter. Most Olympia Chimney cap replacements in Bedford are completed in a single visit, and we carry the common 8″, 10″, and 13″ x 13″ stainless models on our trucks. Homeowners usually discover the problem after a storm, when water spots appear on the firebox ceiling, or when they notice rust flakes in the hearth that weren’t there last burning season.

Which Olympia Chimney Models This Applies To

Olympia Chimney produces several flue systems common in Westchester County homes built between 1985 and 2010, particularly their 600-series and 800-series insulated stainless steel flues. The 600-series uses a 6-inch inner diameter with an 8-inch outer, while the 800-series steps up to 8-inch inner with 10-inch outer, and both require cap adapters that seat differently than standard flue tiles. Check the metal stamp on your flue joint, usually found at the first accessible section above the smoke chamber, or measure the outer dimension at the flue top with a tape measure before calling.

We install OEM Olympia Chimney caps where the flue is still under warranty or where the homeowner wants exact factory matching, but we also stock Gelco and Copperfield stainless caps that mate to Olympia flues with proper adapter rings. The aftermarket route saves roughly $40-$80 on parts without sacrificing fit, though we will tell you straight if your particular flue geometry needs the factory piece. Hearthstone Chimney Co. is an independent service provider, not affiliated with Olympia Chimney.

One compatibility gotcha we see in Bedford: the 800-series flues installed in the wider stone chimneys near Bedford Village often have an extended outer wall that standard 10-inch caps won’t seat over. We measure for this on every job, because ordering by flue series alone leads to a second trip.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust staining on exterior masonry below the crown. When an Olympia Chimney cap’s stainless mesh begins separating from its base ring, water tracks down the flue exterior and oxidizes the steel collar. We catch this early during level-2 inspections, before the rust bleeds through your chimney face.
• Water in the firebox after heavy rain. A cap with compromised seams or a missing storm collar directs water straight down the flue. In Bedford’s freeze-thaw climate, this water expands in the smoke chamber and accelerates liner deterioration.
• Bird or squirrel noise in the flue. Olympia Chimney caps use a specific mesh density, 5/8-inch weave, that blocks nesting animals while allowing smoke passage. When mesh corrodes or blows off in wind, the flue becomes an open invitation.
• Sparks landing on the roof during burning. The cap’s spark arrestor function fails when mesh gaps widen or the cap tilts from loose mounting. This is the symptom that gets our attention fastest, for obvious reasons.
• Visible cap tilt or missing fasteners at the flue top. Olympia’s twist-lock adapters can work loose after years of thermal cycling, especially on flues serving woodstoves that run hot and cold daily. A tilted cap channels water inward instead of shedding it.

Replacement Cost & What’s Included

What drives the range: cap material (304 stainless versus 316 marine-grade for coastal exposure), whether your flue needs a custom adapter for the Olympia twist-lock system, and accessibility. A straightforward walk-up roof in Bedford Hills takes less time than a steep slate pitch on a Katonah colonial. Every cap installation includes a camera inspection of the flue top and a photo report you can see. The 90-Day Done Right Promise covers the work in writing, no arguing. If it needs doing, we will tell you. If it does not, we will tell you that too.

DIY or Call Us?

There is no high-tension spring or electrical hazard in a chimney cap swap, but there is gravity, and there is the roof. An owner can safely check from the ground with binoculars for visible tilt, missing mesh, or rust streaks. You can also verify your flue series from the metal stamp inside the firebox throat.

Where DIY goes wrong: most Bedford roofs are steeper than they look from the driveway, and wet moss on slate or cedar is unforgiving. Beyond the fall risk, seating an Olympia Chimney cap correctly requires checking flue squareness, selecting the right adapter ring, and confirming storm collar overlap, all of which we do from a ladder platform with three points of contact. We have replaced caps that homeowners installed upside down, caps with mesh so tight they blocked draft, and caps that blew off the first windy day because the adapter was never locked.
