Olympia Chimney Chimney Cap Installation Nationwide

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

An Olympia Chimney chimney cap installation in Shelton typically runs $340-$620 depending on flue size and whether the crown needs repair before the cap goes on. We stock Olympia Chimney-compatible caps in 8″, 10″, and 13″ round and standard rectangular sizes on our trucks, and most installs are completed in a single visit. If you’re seeing rust streaks down the flue tile or hearing animals in the chimney, the cap has likely failed and the flue is exposed to everything Shelton weather throws at it.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps fit their own stainless steel and galvanized flue systems, but the critical detail is matching the cap to the flue diameter, not just the brand name. The Olympia 2000 series, 3000 series, and the older galvanized flue lines each use slightly different base dimensions. A 10″ cap ordered by habit will sit crooked on an 8″ flue and funnel water straight onto the crown.

We check three things before ordering: the stamped size on the flue collar (usually visible from the roof), whether the flue is round or rectangular, and the crown condition underneath. Olympia’s stainless caps carry a lifetime warranty against corrosion, but the galvanized models start showing surface rust in coastal Connecticut air within six to eight years. For most Shelton homes we recommend the stainless upgrade, even when the original was galvanized. Hearthstone Chimney Co. is an independent service provider with no affiliation to Olympia Chimney, and we source both OEM Olympia caps and quality aftermarket equivalents from Gelco and Copperfield when the fit calls for it.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust stains on the chimney breast or exterior brick. The cap’s mesh or base has corroded through, and water is carrying iron oxide down with every rain. In Shelton’s freeze-thaw cycles, this accelerates crown cracking below.
• Debris or animal nesting material in the firebox. A missing or damaged cap screen lets squirrels, raccoons, and starlings straight into the flue. We pulled a nest from a Huntington Center chimney last March that had blocked half the flue.
• Water in the firebox after heavy rain. The cap is either gone, tilted from wind, or the lid has separated from the base. Even a quarter-inch gap directs gallons of water down the flue over a season.
• Downdraft smoke even on calm days. The cap’s wind-directional design has bent or the lid is missing. Olympia’s standard caps include a rain skirt that also blocks downward air pressure, and when that deforms, smoke backs up into the room.
• Visible gaps between cap and flue tile. The mounting brackets have corroded or the masonry screws have backed out. This is the early stage, before water damage becomes expensive, and it’s the right time to call.

Replacement Cost & What’s Included

The range depends on roof access, flue height, and whether we find crown damage once the old cap is off. We quote the full number before starting, and that’s the number on the invoice. Every cap install includes a Level-2 camera inspection down the flue, photos you can see, and our 90-Day Done Right Promise in writing. If the cap leaks or shifts, we come back. No paperwork, no arguing.

DIY or Call Us?

An owner can safely check whether the cap is present and level from the ground with binoculars, and can clear light debris from the firebox. That’s where safe DIY ends. Roof work on a pitched surface with a 20-foot drop is genuinely dangerous, and tightening a cap on a corroded flue tile often cracks the tile itself. We’ve been called to jobs where a well-meaning homeowner bent the flue lip and turned a $400 cap replacement into a $1,800 flue repair.

Our technicians carry the right cap sizes, the proper masonry anchors for Shelton’s older brick crowns, and the camera to verify the flue is sound before we leave. Most jobs take under two hours. Call (475) 265-6822 and we’ll give you a straight answer on whether yours needs attention now or can wait until your annual sweep.
