Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
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 Bangor Owner’s Guide
An Olympia Chimney chimney cap installed by our team in Bangor typically runs $340-$620 depending on flue size and whether the crown needs repair before mounting. We stock Olympia Chimney-compatible caps in 8″, 10″, and 13″ round plus standard rectangular sizes, and most replacements are completed in a single visit. If you’re seeing rust streaks down your chimney chase or hearing animals in the flue, the cap is likely compromised and letting moisture and pests into the system.
We’ve replaced more failed chimney caps in Bangor than we can count, especially on homes built in the 1970s and 1980s near the Bushkill Creek watershed where the humidity swings hard between seasons. A clean flue does not need a sales pitch. What it needs is a cap that fits the flue properly, vents the smoke, and keeps the rain out. That’s what an Olympia Chimney cap is engineered to do, but only if it’s the right model and seated on a sound crown.
Which Olympia Chimney Models This Applies To
Olympia Chimney manufactures caps across several product lines, and the critical distinction for Bangor homeowners is between their standard galvanized series, stainless steel series, and copper line. The galvanized caps carry a 5-year warranty and start showing rust at the seams around year 7 in Pennsylvania’s freeze-thaw cycle. The stainless series, typically 304 or 316 grade, handles Bangor’s wet winters without corroding. Copper caps patina green and last decades but cost roughly double.
To identify your cap, look for the Olympia Chimney stamp on the underside of the lid or a model tag on the mesh screen frame. Common identifiers include the OC-800 round series, OC-1000 for larger flues, and the OC-rectangular line for multi-flue chimneys. If the tag is rusted off, measure the flue opening precisely, outer edge to outer edge. A cap that overhangs by less than 2″ on each side will channel water onto the crown instead of away from it. That’s a common installation error we correct on Bangor homes.
We are an independent service provider, not affiliated with Olympia Chimney. We source their caps through authorized distribution and also stock quality aftermarket equivalents from Gelco and Famco when the application calls for it. The aftermarket caps match Olympia Chimney specs but sometimes run thicker gauge mesh, which matters if you’ve had bee or bird problems before.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Rust stains on the chimney brick or siding below the cap. The cap’s lid or base flange has corroded through at a seam or fastener hole. Once water finds that path, it runs down the chase and stains the masonry. In Bangor, we see this accelerate after winters with heavy ice damming on the roof.
- Mesh screen pulled away from the frame or gaping at corners. Squirrels and raccoons in the Bangor area test every weak point. Olympia Chimney caps use welded mesh, but if the cap was forced onto an oversize flue, the tension bends the frame and creates an entry point.
- Water in the firebox or rust on the damper. This means the cap is either missing, lifted by wind, or the lid has blown off entirely. We’ve found caps in Bangor yards after March windstorms that the homeowner didn’t notice were gone until the first fall fire.
- Downdraft smoke even on calm days. The cap’s design creates a slight vacuum to draw smoke upward. If the lid is dented or installed too low, that aerodynamics fail and smoke spills into the room. Older Bangor homes with shorter chimneys are especially prone.
- White efflorescence blooming on exterior brick below the cap. Water is entering behind the cap, saturating the masonry, and pulling salts to the surface. This indicates either a failed cap seal or a crown that has cracked underneath the cap flange.
Replacement Cost & What’s Included
| Service Component | Typical Range in Bangor |
|---|---|
| Olympia Chimney stainless cap (standard flue) | $180-$290 |
| Olympia Chimney copper cap | $340-$480 |
| Crown repair/prep before cap mount | $120-$280 |
| Installation labor | $140-$190 |
| Total installed (most common) | $340-$620 |
What drives the range: flue height above the roofline, whether we need to work from a ladder or set up scaffolding, and the condition of the existing crown. We don’t mount a new cap on a crumbling crown; it’ll leak within two seasons and you’ll be calling us back. Our estimate includes a camera inspection of the flue interior, photos you can see, and a plain-English verdict on whether the crown needs work. The number on the estimate is the number on the invoice. Every cap installation carries our 90-Day Done Right Promise - in writing, no arguing.
DIY or Call Us?
There’s a safe middle ground here. A homeowner can check whether the cap is present, whether it’s sitting level, and whether the mesh is intact from ground level with binoculars. You can also measure your flue opening from the roof if you’re comfortable on a ladder and the pitch is walkable.
Where DIY goes wrong: working near the roof edge with tools while reaching across the flue. The cap itself isn’t dangerous, but the fall risk is real, and a cap forced onto the wrong size flue will leak or blow off. We’ve also seen homeowners seal the cap to the crown with the wrong caulk, trapping moisture underneath and rotting the crown faster. Our technicians carry the proper high-temp silicone and know the Olympia Chimney mounting hardware by sight. Most jobs take under 90 minutes, and we complete them in a single visit. If you’d rather not climb the roof, call (610) 609-7634 and we’ll give you a free estimate with upfront pricing.
FAQs
A galvanized Olympia Chimney cap typically lasts 7-10 years in Pennsylvania’s climate before rusting at the seams; stainless steel caps often go 15-20 years. Bangor’s location in the Lehigh Valley means wet springs and freeze-thaw winters that test metal at every joint. Call (610) 609-7634 if you’re unsure of your cap’s age - we can date it by the model stamp and condition.
Minor mesh damage can sometimes be rewired, but a rusted lid or bent frame is not worth repairing - the cap won’t seat properly and will leak. We don’t patch caps because the labor cost approaches replacement and the result is temporary. For a straight answer on your specific cap, call (610) 609-7634 for a free inspection.
Most Olympia Chimney cap replacements take 45-90 minutes from ladder set to cleanup, assuming the crown is sound. If crown repair is needed, add 2-3 hours for proper curing before the cap mounts. We complete most jobs in a single visit, and you’ll get photos of the finished work.
We carry the most common Olympia Chimney stainless cap sizes - 8″, 10″, and 13″ round plus standard rectangular - on every service vehicle. Less common sizes and copper caps are available next-day through our distributor. We’ll confirm availability when you call (610) 609-7634 so we don’t waste your time with a second trip.
