Olympia Chimney Chimney Cap Installation Nationwide

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

We stock and install Olympia Chimney-compatible chimney caps across Alpharetta, with most jobs running $285-$520 installed depending on flue size and whether your crown needs resealing. Same-day installation is available when we have your spec in the warehouse or on the truck. Most Alpharetta owners figure out something’s wrong when water spots appear on the firebox ceiling or they hear flapping during the spring storms that roll off the Chattahoochee.

Corrine Halstead and our crew have replaced Olympia caps on homes from downtown Alpharetta out to Webb Bridge Road near Wills Park. The camera doesn’t soften anything, and neither do I - we show you the rust pattern or mesh corrosion before we quote anything in writing.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps come in several product families, and getting the match right matters because the mounting flange geometry differs. The WeatherShield series uses a bolt-down base ring with 1/4-inch stainless hardware that seats into pre-threaded receiver holes on the crown. The Champion line relies on a compression-fit skirt with integrated storm collar, which works only if your flue tile projects at least 3/4 inch above the crown surface. The Pro-Top multi-flue models span two or three flue terminals with a single hood and require exact center-to-center measurements within 1/8 inch.

To identify yours, check the stamped model number on the underside of the existing cap’s hood or the riveted tag on the mesh screen frame. If corrosion’s eaten the tag, measure the flue tile outer dimension and the crown footprint. We carry OEM Olympia caps through Haven’s buying network, plus Gelco and Famco equivalents that meet the same 304 stainless and 18-gauge mesh spec when the OEM lead time stretches past what Alpharetta weather will allow.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Water staining on firebox walls or damper plate. The cap’s hood has shifted or the storm collar seal has cracked, letting wind-driven rain enter during Alpharetta’s March and November storm cycles. We see this most often on east-facing flues that take the full brunt of weather coming off the river corridor.
• Rust flakes or orange streaking on the chimney exterior. The 304 stainless mesh has begun pitting, usually at the weld points where dissimilar metal contact accelerates corrosion. Once pitting reaches 1/16 inch depth, the mesh won’t pass a Level 2 camera inspection for spark containment.
• Bird or squirrel nesting debris in the firebox. The screen mesh has separated from its frame or a corner tab has broken, creating an entry gap. In Alpharetta’s older subdivisions like Windward or Country Club of the South, we find this after owners notice chirping or smell decay from above the damper.
• Cap hood lifting or rattling in wind. The mounting bolts have backed out or the compression skirt has lost tension from thermal cycling. A loose cap becomes a projectile risk above 40 mph gusts and can damage shingles or gutters on the way down.
• Downdraft smoke spillage on windy days. The cap’s internal baffle has corroded through or the hood height is wrong for your flue draw. This shows up suddenly when owners fire the first fall burn and the living room fills with smoke.

Replacement Cost & What’s Included

Every installed cap includes new stainless hardware, a bead of crown sealant at the base perimeter, and torque verification. The price range moves with flue height above the roofline (two-story homes in Alpharetta’s newer sections add ladder time) and whether we need to fabricate a skirt extension for an unusually thick crown. We deliver a written price before any work starts, per Haven Standard Clause 1, and back the installation with our 365-Day Done Right Promise. Materials come through Haven’s buying network, procured from Olympia Chimney, Gelco, Famco, and Copperfield to keep customer prices honest.

DIY or Call Us?

An owner can safely check whether the cap bolts are finger-loose or whether debris is visible on the mesh from ground level with binoculars. Do not climb the roof to tighten hardware or remove the cap yourself. The combination of Alpharetta’s composite shingle slope angles, morning dew, and the 12-15 foot working height on typical two-story homes creates a genuine fall hazard, and a dropped cap corner can slice through a gutter or dent a car below.

Removing a seized bolt without stripping the crown anchor, seating a new storm collar with proper pitch for drainage, and verifying mesh spark arrestor compliance against NFPA 211 are where DIY goes wrong. We bring the right tap set, the torque spec sheet, and the camera to confirm the flue interior stayed clean through the swap. Call (678) 679-0171 and we’ll quote it in writing before we dispatch.
