Olympia Chimney Chimney Cap Installation Nationwide

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

We stock and install Olympia Chimney-compatible chimney caps throughout Littleton, with most jobs running $285-$475 installed depending on flue size and whether your crown needs repair before the cap goes on. Same-day installation is usually available when you call before noon, and we carry the common Olympia Chimney sizes on every truck. Most Littleton homeowners discover their cap has failed after a storm blows it loose, they spot rust streaks running down the masonry, or a neighbor mentions birds nesting in their flue.

Which Olympia Chimney Models This Applies To

Olympia Chimney caps fit their stainless steel and galvanized flue liner systems, and the critical detail is matching the cap to your liner diameter, not just the chimney’s exterior dimensions. We’ve seen homeowners in Littleton order a cap based on the brick opening and end up with a half-inch gap that lets rain straight through. Check the stamped size on your Olympia Chimney liner collar, usually visible at the flue top, or measure the inner diameter with a tape measure, not the outer brick.

The Olympia Chimney OEM caps use 304 stainless with a welded seam at the lid joint. Aftermarket equivalents from Gelco and Famco, which we also stock, match the spec at a lower price point but use a crimped seam that can separate after seven to ten years in Colorado’s freeze-thaw cycle. For Olympia Chimney’s 6-inch, 7-inch, and 8-inch round liners, we keep both options on the truck. If your system is the older Olympia Chimney oval-flex series, we need to order the adapter base, which adds two business days. The camera doesn’t have an opinion - it just shows you what’s there, and that includes whether your liner collar is round or oval before we quote.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

• Rust stains on the brickwork below the crown. Olympia Chimney caps use a galvanized mesh on their economy line that corrodes from the inside out in Littleton’s snow-melt cycles. By the time you see orange streaks, the mesh has already thinned enough to let embers through.
• The cap tilts or sits crooked after wind. The mounting bracket on older Olympia Chimney units uses a single-band tension clamp. After five to seven Front Range winters, that band fatigues and won’t hold torque, especially on south-facing chimneys that expand and contract daily.
• Birds or squirrels in the flue. A cap with separated mesh sides or a lifted lid creates an entry point. We’ve pulled nests from Olympia Chimney systems in Columbine Knolls where the homeowner assumed the cap was fine because it looked intact from the ground.
• Water in the firebox after heavy rain. The Olympia Chimney cap lid is designed with a 1.5-inch overhang minimum. If the lid has dented or the mounting bolts have loosened, water tracks down the liner and pools behind the damper.
• Spalling brick on the chimney top course. This is the expensive one. A failed cap lets moisture into the crown, which freezes, expands, and pops the brick face off. We’ve replaced crowns on Littleton homes where the cap was missing for just two seasons.

Replacement Cost & What’s Included

Every price is written before we start, with the scope and warranty on the same page. The range depends on liner diameter, whether your existing mounting band is reusable, and if the crown needs resurfacing before the new cap seals properly. We source Olympia Chimney caps through Haven’s buying network alongside DuraFlex, HeatShield, and Gelco, which keeps our prices honest and our stock current. The 365-Day Done Right Promise applies to every installation, and Clause 4 of the Haven Standard requires a photo record of the finished work, including the cap seated on the liner collar.

DIY or Call Us?

You can safely check whether your cap is loose by sighting up from the ground with binoculars, or by tapping the side of the flue with a long pole to hear if the cap rattles. Do not climb the roof to tighten bolts or remove a stuck cap. The combination of steep pitches common in Littleton’s Ken Caryl and Roxborough subdivisions, plus the 30-foot-plus drops on many two-story homes, makes this a fall risk even for experienced DIYers.

More importantly, an improperly seated cap creates a false sense of security. We’ve found caps that homeowners reinstalled themselves with deck screws instead of the stainless tension band, which held for one season then blew off in a March windstorm and took a section of crown with it. If you’re comfortable on a ladder and can reach the flue top from a safe position, you can measure the liner diameter and photograph the mounting hardware. For everything else, call (720) 439-4666. Corrine Halstead or a member of our crew will walk through what we found on camera and give you a written price before any work starts.
