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 Woodland Park Owner’s Guide
We stock and install Olympia Chimney-compatible chimney caps throughout Woodland Park, with most cap replacements running between $285 and $540 installed depending on flue size and cap model. If you call before noon on a weekday, we can usually have Wendell or a crew member on your roof the same week, cap in hand. Most Woodland Park homeowners find out their cap has failed the hard way: they spot rust flakes on the patio, hear rain drumming down the flue, or notice birds working twigs through the mesh. Sometimes it’s a hailstorm that leaves the lid dented like a soda can. Whatever the clue, the fix is usually one trip up the ladder.

Key takeaways:
- We keep common Olympia Chimney cap sizes on the truck, so most Woodland Park jobs are one visit
- Every install includes a camera check of the flue top so you see the fit before we come down
- All work carries the 90-Day Done Right Promise in writing
- We’re an independent local company, not affiliated with Olympia Chimney, and we’ll tell you if a cheaper universal cap does the job just as well
Which Olympia Chimney Models This Applies To
Olympia Chimney makes caps for a few distinct product lines, and the part that fits one will not always fit another. The three you’ll most likely see on a Woodland Park roof are the Vacu-Stack, WindBeater, and the standard OC-mesh cap series. If you have the original paperwork, the cap part number usually starts with “OC” followed by the flue diameter in inches, like OC-13 for a 13-inch flue. No paperwork? No problem. We measure the outside tile or liner diameter across the flue opening before anything gets ordered or pulled off the truck. That measurement is the one number that matters.
One gotcha worth knowing: the Vacu-Stack line relies on wind to create draft, which means it needs exact sizing to work as designed. A cap that’s even a half-inch off in fit can whistle in a March wind and drive you up the wall by April. We have seen aftermarket copies that look close but sit loose, and in a place like Woodland Park where winter winds come down off Garret Mountain, loose is not acceptable. We stock genuine Olympia and quality aftermarket equivalents, and we will give you the straight answer on which one makes sense for your stack.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Rust streaking down the chimney chase or crown. The cap base and mesh take the brunt of New Jersey weather. Once the galvanized coating breaks down near the weld points, brown streaks show up within a season. That’s not cosmetic; that’s the clock running on the cap’s structure.
- Mesh torn or bulging outward. Raccoons and squirrels in Woodland Park will work at weak mesh to get to the warm flue. A bulge means an animal has been leaning on it. A tear means it got in or almost got in.
- Rain dripping down the damper or pooling in the firebox after a storm. A cracked or missing cap lid turns your flue into a drainpipe. We have opened dampers in Woodland Park and found an inch of standing water from one bad summer storm.
- Debris inside the fireplace after windy days. Leaves, twigs, and roof grit shouldn’t be inside your firebox. If they are, the cap’s spark screen or lid has a gap somewhere.
- A sudden drop in draft or smoke rolling back into the room. A partially blocked cap from nesting material or a collapsed lid restricts airflow. Your flue doesn’t care how the fire looks. It cares how it breathes.
Replacement Cost & What’s Included
Here is what you should expect to pay for a chimney cap installation in Woodland Park:
- Standard mesh cap, 13×13 or smaller: $285-$365 installed
- Larger or custom flue sizing: $380-$540 installed
- Vacu-Stack or WindBeater cap (draft-improving models): $420-$610 installed
The range comes down to two things: the cap size and whether we need a mounting bracket or new crown screws. The price Wendell gives you on the phone is the price on the invoice. No add-ons after the fact. Every cap swap includes removing the old unit, checking the crown surface for cracks, installing the new cap with stainless hardware, and a photo of the finished work from the roof.
We also apply the standing discounts: $40 off any repair over $200, and 10% off for seniors and veterans. Inside our service county, there is no trip charge.

DIY or Call Us?
I’ll be straight with you: a chimney cap swap is one of the safer chimney jobs to attempt, but only if you’re comfortable on a roof with a proper extension ladder and a second person holding it steady. If your roof is steep, wet, or you don’t have the right ladder, the hospital bill will make a $300 cap look cheap. The part of this job that goes wrong for most homeowners is the fastening. The cap needs to be anchored into crown material or secured with a tension band that fits the flue exactly. A cap that’s just set on top will be in your neighbor’s yard by Thanksgiving.
What you can safely check from the ground: visible rust, tilted cap, missing lid, or mesh that looks pushed in. If you see any of that, call us at (973) 846-1622. If we come out and the cap is still sound, Wendell will tell you that first. If it does not need doing, I will tell you that first.
FAQs
In Passaic County weather, a galvanized steel Olympia cap typically lasts 8 to 12 years before rust or storm damage catches up with it. Stainless versions can go 15 years or more. Coastal salt air is not a factor here, but freeze-thaw cycles and acidic rain are. If your cap is older than a decade, it owes you nothing and is worth a look before burning season.
Small tears in the mesh can sometimes be patched with stainless wire, and a loose lid can be re-secured, but once the base or weld points are rusted through, patching is throwing good money after bad. Wendell will show you the camera footage and give you a plain-English verdict, every time, no exceptions.
A straightforward cap replacement takes 45 minutes to an hour once we’re on the roof. If the crown needs minor patching around the flue, add another 30 minutes. You’ll know the total before the work starts.
We carry the most common sizes and a few draft-improving models on the truck, so many Woodland Park jobs are done in one visit. If yours is an odd size or a specialty model, we order it and typically have it in hand within a few business days. Call (973) 846-1622 with your flue measurement and we can check stock while you’re on the phone.
