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

Olympia Chimney chimney cap installation in Dallas typically runs $280-$520 for most residential flues, including the cap, collar, and labor, and we stock the common Olympia Chimney sizes on our trucks for next-day scheduling. Corrine Halstead and our crew have fitted these caps on Dallas homes from Lakewood to Lake Highlands, where the combination of clay flue tiles and sudden spring hailstorms makes proper fitment critical. Most owners realize they need a new cap when water starts showing up in the firebox or the draft smells wrong on humid August mornings.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps are sized to three flue collar standards: 8×8, 8×12, and 13×13, with adjustable-base models that fit the 8×8 and 8×12 range without field modification. The critical compatibility gotcha in Dallas is flue tile height above the crown: Olympia Chimney’s standard 5-inch mesh skirt works on tiles protruding 2 to 4 inches, but many Preston Hollow homes built in the 1960s have flush or recessed tiles that need the extended 8-inch skirt or a custom-fabricated base plate. We carry both on the truck.

The model number is stamped on the underside of the existing cap’s lid, usually starting with “OCC-” followed by the mesh dimension. If the cap is already gone, we measure the flue tile outside dimensions with a tape and check the crown slope for water pooling. OEM Olympia Chimney caps carry a 20-year warranty on the 304 stainless mesh; the aftermarket Gelco equivalents we also stock match that spec at a lower price point and fit the same collar pattern. For homes in the Swiss Avenue historic district with terra cotta flues, we typically recommend the OEM cap for the tighter tolerance on irregular tile edges.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust stains running down the chimney face. Olympia Chimney caps use 304 stainless mesh, but the spot-welded collar seam can fail after 12-15 years in Dallas humidity, letting water wick behind the cap and oxidize the attachment hardware. We see this most on north-facing exposures in Highland Park where the cap never fully dries after rain.
• Water in the firebox after storms. A cap that has shifted on its collar or lost its storm bolts lets wind-driven rain enter at the mesh-to-lid joint. In Dallas, this happens during March and October frontal systems when winds hit 40 mph sustained.
• Bird or squirrel noise in the flue. The mesh on an Olympia Chimney cap is 5/8-inch square; if corrosion opens a gap at the weld or the lid separates from the skirt, animals can push through. We pulled a nest from a Lochwood cap last February where the homeowner had heard scratching for three weeks.
• Draft reversal on still, humid days. A cap whose mesh has collapsed inward or whose lid is dented from hail disrupts the pressure differential that draws smoke upward. Dallas summer inversions make this worse, especially in low-lying neighborhoods near White Rock Creek.
• The cap is visibly tilted or missing. High winds or improper original installation can loosen the tension bolts that secure the collar to the flue tile. An angled cap catches wind like a sail and will eventually depart entirely, often taking a section of flue lip with it.

Replacement Cost & What’s Included

What drives the range: flue tile condition, whether the crown needs minor patching to seat the new collar, and whether we need the extended skirt. Every job gets a written price before work starts, per Haven Standard Clause 1. The 365-Day Done Right Promise covers the installation; the cap itself carries the manufacturer’s warranty. We include a camera inspection of the flue interior and a photo record of the completed work under Haven Standard Clause 4, same as every visit since 2009.

DIY or Call Us?

You can safely check whether your cap is loose by sighting from the ground with binoculars, looking for tilt, missing storm bolts, or mesh collapse. Do not climb the roof. Chimney cap work involves working at height on a sloped surface, often near power lines, and a dropped cap or tool can cause serious injury. The collar tension bolts on an Olympia Chimney cap require a specific torque to seal without cracking the flue tile, and we’ve seen DIY overtightening split tiles that then needed $800+ in crown repair.

Camera goes in first. Everything else follows. We’ll scan the flue, measure the tile, and give you a written price before anyone touches a ladder. Call (972) 284-1392.
