Worth knowing

Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

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

An Olympia Chimney chimney cap installation in Marietta typically runs $285 to $520 installed, and we complete most cap replacements in a single visit. The cap sits at the very top of your chimney and does three jobs: it keeps rain out of your flue, blocks embers from escaping onto your roof, and stops birds and squirrels from nesting inside. Most Marietta homeowners discover theirs has failed when they spot rust streaks running down the chimney crown, hear animals scratching in the flue, or find water staining on the ceiling near the fireplace after a hard Georgia downpour.

We work with Olympia Chimney caps because they’re built for exactly this climate: hot, humid summers followed by real winter freeze-thaw cycles up here in Cobb County. The wrong cap, or a universal fit that doesn’t actually fit, fails early. We stock Olympia Chimney-compatible caps on our trucks for the models we see most in Marietta, and Cory Mitchell can usually photograph the failed cap, show you what happened, and get the replacement ordered that same day if it’s a size we don’t carry.

Which Olympia Chimney Models This Applies To

Olympia Chimney makes venting systems for both masonry fireplaces and manufactured wood stoves, and the cap compatibility depends on which system you have. For masonry chimneys, Olympia caps are sized to the outside diameter of your flue tile, not the inside. That’s the most common measuring mistake we see in Marietta: a homeowner measures the inside opening, orders a cap based on that number, and it arrives too small to seat properly over the tile. For Olympia’s stainless steel prefab systems, the cap locks onto the specific pipe diameter, usually 6-inch or 8-inch, and the model number is often stamped on the pipe section just below the cap.

The OEM-vs-aftermarket decision for Olympia is straightforward. If you have an Olympia stainless system, we recommend staying with Olympia or a direct-compatible equivalent, because the locking tabs and mesh sizing are engineered to that specific pipe. For masonry chimneys, we have more flexibility: a quality stainless steel cap from Copperfield or Gelco will often outperform the original, especially if the original was galvanized rather than stainless. Galvanized caps on Olympia masonry systems are the ones we see rusted through in eight to ten years. We’ll show you the difference in the photos before you spend a dollar, and we’ll tell you plainly if a less expensive aftermarket cap will do the job just as well.

Signs Your Olympia Chimney Chimney Cap Installation Is Failing

  • Rust streaks running down the chimney crown or brick. This means the cap body is rusting through, and every rain is now washing oxidized metal into your masonry. Once the screen mesh starts rusting, it will sag and eventually drop into the flue.
  • Water in the firebox or dripping sounds during rain. A failed cap lets rain run straight down the flue. In Marietta, our spring storm season will find this fast. One hard thunderstorm is enough to tell you whether the cap is still doing its job.
  • Birds, squirrels, or raccoon sounds from inside the chimney. The mesh on a functioning cap keeps animals out. A torn or missing mesh is an open door. We’ve pulled nesting material out of flues in East Marietta that filled two garbage bags.
  • Debris falling into the fireplace between uses. Leaves, twigs, and roof granules dropping into your firebox mean the cap’s screening has failed or the cap itself has shifted off the flue. That debris is also drying out inside your chimney right now, which is a fire hazard when you light the next fire.
  • A cap that moves when you touch it. If you can see the cap from the ground and it’s visibly cocked, or if you’re comfortable on a ladder and it shifts by hand, the mounting hardware has failed. A loose cap is a matter of time before it comes off entirely in a windstorm.

Replacement Cost & What’s Included

In Marietta, an Olympia Chimney chimney cap installation generally falls between $285 and $520 depending on flue size, cap type, and whether the chimney crown needs patching around the mount. Smaller single-flue stainless caps on masonry chimneys sit at the lower end. Larger multi-flue caps, or caps for Olympia’s 8-inch stainless systems, run higher because the parts cost more and the install takes longer.

Here’s what that price includes when you book with us:

  • Written price before any work starts. You approve the number on paper or on screen, then we touch the chimney. No surprises.
  • The cap itself at our parts cost. We show you what the part costs us before we mark it up for the job.
  • Removal of the failed cap and inspection of the flue top underneath it.
  • Proper mounting with stainless hardware, and crown patching if the old cap’s mounting point has crumbled.
  • Photos after the job, so you can see exactly what was installed and how it’s seated.
  • The 365-Day Done Right Promise. If the installation fails within a year, we fix it free of charge. That’s a written guarantee on every repair, not a verbal promise.

DIY or Call Us?

The honest split here: if you’re comfortable on a ladder and your roof pitch is walkable, you can absolutely inspect your existing cap and take measurements. Cory will tell you the same thing: get on the ladder, check if the mesh is intact, measure the outside dimensions of the flue tile, and send us a photo. What goes wrong with DIY is the installation itself. A cap that’s not seated level lets rain in around the base. A cap that’s overtightened cracks the flue tile. A cap installed with the wrong anchor into a soft Georgia-fried crown will work loose within a year. And working at chimney height on a ladder with a drill in one hand and a cap in the other is how people end up in the emergency room.

If the photo shows a simple swap on a single-story roof with an easy pitch and you want to try it, we’ll tell you the cap to buy and what not to do. If it involves a two-story roof, a steep pitch, or a crown that’s already crumbling, call us before you go up there. Call (762) 249-4619, and we’ll give you a straight answer about whether it’s a safe DIY job or a job for a trained tech with roofing gear.
