Olympia Chimney Chimney Cap Installation Nationwide

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

We stock and install Olympia Chimney-compatible chimney caps across Marietta, with most jobs running $285-$475 installed depending on flue size and whether your crown needs sealing work. Most Marietta homeowners who call us noticed water staining on their firebox ceiling or heard rustling after a storm - both point to a cap that’s failed or was never properly fitted to the flue tile. We carry the common Olympia Chimney cap sizes on our trucks and can typically measure, match, and install within a single visit.

Which Olympia Chimney Models This Applies To

Olympia Chimney produces stainless steel and galvanized chimney caps across several product lines, and the critical detail is matching the cap to your flue’s outer dimension, not the chimney brand stamped on the firebox. The Olympia 8″ round, 13×13 square, and 13×18 rectangular caps cover roughly 80% of the Marietta homes we service, particularly the 1980s-2010s builds in East Cobb and the neighborhoods off Whitlock Avenue where factory-built metal chimneys were common.

Check the raised stamp on your existing cap’s lid or the metal tag on the chimney chase cover - Olympia marks series numbers like OLY-SS-813 or OLY-GV-1013. If the tag is rusted off (common after five Georgia summers), we measure the flue tile’s outer edge with a sliding caliper on the roof. That’s the number that matters. We source Olympia Chimney caps direct through Haven’s buying network, and we also stock Gelco and Famco equivalents when an Olympia OEM backorder would delay your job. The aftermarket caps we use match 304 stainless steel gauge and mesh spec - we won’t substitute down to galvanized on a stainless flue, and we’ll tell you in writing if we do.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Water stains on the firebox ceiling or smoke chamber walls. A warped or missing Olympia Chimney cap lets rain run straight down the flue. In Marietta’s March-May storm season, we see this weekly - the water mixes with creosote and etches the metal firebox floor.
• Bird or squirrel sounds from above the damper. The ¾-inch mesh on an Olympia Chimney cap keeps animals out while letting smoke escape. When mesh corrodes or a cap blows off in wind, chimney swifts and gray squirrels treat your flue like a hollow tree.
• Rust flakes or orange streaks on the firebox walls. This means moisture has been entering long enough to oxidize the steel damper frame or firebox lining. The cap’s seal against the flue tile has failed, or the lid’s drip edge is cracked.
• Smoke spillage on windy days even with the damper open. A properly designed Olympia Chimney cap creates a slight updraft assist. When the lid is dented or installed too low, wind pressure across the roof can force smoke back down - we see this on homes near Kennesaw Mountain where the ridge accelerates airflow.
• The cap is visibly tilted, missing screws, or sitting loose on the flue. Expansion and contraction from Georgia’s freeze-thaw cycles loosen strap-leg mounts. An Olympia cap held by two loose screws will torque in the next storm and either fall or take the top flue tile with it.

Replacement Cost & What’s Included

What drives the range: flue height above the crown (taller = more ladder time), whether we need to remove a damaged cap that’s rust-welded to the flue tile, and if the crown itself has spalling that needs sealing before the new cap goes on. We photograph the crown condition during our camera scan and show you before quoting. Every Olympia Chimney cap installation includes a written scope, written warranty, and the 365-Day Done Right Promise stamped under Haven Standard Clause 1. We don’t start until you’ve seen the price in writing.

DIY or Call Us?

There’s no spring tension or electrical hazard on a chimney cap, but there is a 20-plus-foot fall hazard and a real chance of damaging the flue tile. An Olympia Chimney cap installed wrong - loose straps, no bead of sealant, wrong overhang - channels water into the crown instead of away from it. We’ve been called to Marietta homes where a homeowner’s weekend project cost them a $1,400 crown rebuild because the cap leaked at the corners for two years unnoticed.

What you can safely check from the ground: binoculars for tilt, missing mesh, or visible rust. What requires a roof visit: measuring flue tile outer dimensions, checking crown integrity, and verifying the cap’s internal clearance above the flue opening. We run a camera down the flue before we quote - Clause 4 of the Haven Standard requires it - so you see what we see. Camera first, quote second, work third - in that order, every time.
