Olympia Chimney Chimney Cap Installation Nationwide

Olympia Chimney Chimney Cap Installation: The Cherry Hill Owner’s Guide

An Olympia Chimney chimney cap installed by Hearthstone Chimney Co. in Cherry Hill typically runs $340-$620 depending on flue size, cap style, and whether the crown needs repair before mounting. We stock the most common Olympia Chimney stainless steel and galvanized caps on our trucks, and most Cherry Hill installations are completed in a single visit. If you’re seeing rust streaks down your brick or hearing water drip in the flue during a March rain, the cap is the first place we look.

We’ve fitted Olympia Chimney caps on everything from 1980s split-levels near Springdale to the deeper-set fireplaces in Barclay Farm colonials. The chimney either draws the way it should, or it does not - and we will not leave until we know which.

Which Olympia Chimney Models This Applies To

Olympia Chimney produces caps across several product lines, and matching the right series matters more than most homeowners realize. Their stainless steel line - typically marked with an “SS” prefix on the part label - fits standard masonry flues from 8×8 inches up to 13×13 inches. The galvanized utility caps, common on older Cherry Hill homes with original construction, carry “GAL” markings and tend to run slightly smaller in the collar depth. We also see their wind-directional caps, which rotate with airflow to reduce downdraft, on homes near the Cooper River where the breeze off the water can push smoke back into the living room.

To identify your cap, check the stamped label on the underside of the existing cap or measure the flue tile opening at the crown. Olympia Chimney’s collar depths range from 1-1/2 inches to 3 inches depending on the series, and a mismatch here means water runs straight down the flue wall. We carry both OEM Olympia Chimney caps and professional-grade equivalents from Gelco and Famco that match the same specs. For most Cherry Hill installations, we recommend the stainless route: the salt air from the Delaware Valley accelerates galvanized corrosion, and we’ve pulled too many rusted-through GAL caps off twenty-year-old homes in the Erlton section to pretend otherwise.

Signs Your Olympia Chimney Chimney Cap Is Failing

• Rust stains bleeding down the chimney brick. Olympia Chimney’s galvanized caps begin surface rusting at the weld points after about 12-15 years in South Jersey’s freeze-thaw cycle. Once the rust reaches the drip edge, it channels water directly onto the crown instead of away from it.
• Water dripping or pooling in the firebox after rain. A cap with a cracked or missing mesh screen, or a collar that has pulled away from the flue tile, lets rain enter the flue. In Cherry Hill’s clay-heavy soil, that moisture wicks into the surrounding masonry and accelerates spalling.
• Debris, leaves, or animal nesting material in the firebox. The mesh sides on Olympia Chimney caps are 5/8-inch weave on most models. When that mesh corrodes through or gets bent by falling branches, squirrels and starlings treat your flue like a rental property.
• Sudden downdraft or smoke rollout when the wind picks up. The cap’s lid should sit high enough to create a venturi effect that draws smoke upward. If the lid has sagged from heat fatigue or the support brackets have cracked, the draft pattern reverses.
• Visible gaps between the cap collar and the flue tile. Thermal expansion in Cherry Hill’s summer heat loosens cement-based mounting over time. A gap as small as a quarter-inch is enough to funnel a surprising volume of water into the chimney structure during a driving northeaster.

Replacement Cost & What’s Included

In Cherry Hill, an Olympia Chimney cap replacement from Hearthstone Chimney Co. breaks down as follows:

• Standard stainless steel cap, installed: $340-$480
• Wind-directional or custom-size stainless cap: $480-$620
• Crown repair or re-cementing required before mounting: add $180-$340
• Level-2 camera inspection with photo report: included with every cap installation

The range depends on flue dimensions, roof access (steep pitches in the Woodcrest area take longer), and whether we find crown damage once the old cap is off. We quote the full number before any work begins - no surprises on the bill. Every cap installation carries our 90-Day Done Right Promise in writing. If water gets past that cap, we come back and make it right, no arguing.

DIY or Call Us?

Checking your cap from the ground with binoculars is sensible. Verifying the mesh is intact and the lid hasn’t tilted - that’s information we welcome when you call. But climbing a roof in Cherry Hill to remove a seized cap and cement a new collar is where DIY turns costly. The flue tile lip is brittle after decades of heat cycling, and levering the old cap free without cracking it takes knowing how the cement was originally bedded. We’ve rebuilt crowns for homeowners who tried the swap themselves and broke the tile edge.

We carry Olympia Chimney-compatible caps on every truck, and most Cherry Hill jobs take under two hours from ladder set to final photo. Call (856) 543-2929 and we’ll give you a straight answer on whether yours can wait until fall or needs handling before the next heavy rain.
