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 Hicksville Owner’s Guide
An Olympia Chimney chimney cap installation in Hicksville typically runs $340-$680 depending on flue size and whether the crown needs repair before mounting. We stock Olympia Chimney-compatible caps in 8″, 10″, and 13″ round flue sizes, plus rectangular models for their multi-flue systems, and most installations finish in one visit. Homeowners usually notice the problem after a windstorm off the Long Island Sound sends water down the flue, or when they spot rust streaks on the brickwork that weren’t there last season.
Which Olympia Chimney Models This Applies To
Olympia Chimney caps fit their own 304 stainless steel flue liners and factory-built chimney systems, but the sizing protocol differs from other brands. Their round caps use outside-diameter mounting, not inside-fit like some competitors, so a 10″ Olympia liner takes a 10″ cap measured at the flue’s exterior rim. We’ve learned to double-check this in Hicksville’s Levittown-adjacent splits and the older colonials off Jerusalem Avenue, where previous owners sometimes mixed Olympia liners with aftermarket caps that never seated right.
Look for the Olympia stamp on the flue collar or the model tag riveted to the chase cover. Common series we see in Nassau County include the OL round flue line and the OLM multi-flue systems. OEM Olympia caps carry their part number prefix (OL- or OLM-) and use heavier 24-gauge stainless with welded seams. Quality aftermarket equivalents from Gelco or Famco match the specs but may use 26-gauge material, fine for most Hicksville applications unless you’re directly exposed to salt air near the Southern State. We carry both and will show you the difference before you decide.
Signs Your Olympia Chimney Chimney Cap Installation Is Failing
- Water staining on the firebox walls or smoke chamber. The cap’s mesh screen has separated from the lid, or the mounting brackets have corroded through. In Hicksville, we see this accelerate where downspouts dump roof runoff against the chimney base and wick upward.
- Rust-colored streaks running down the exterior brick or siding. The cap’s galvanized hardware is failing, or the stainless lid has developed pinholes from salt corrosion. Olympia’s 304 stainless resists this better than bargain caps, but the mounting screws are often standard steel and go first.
- Birds or squirrels audible in the flue, or nesting debris falling into the fireplace. The cap’s mesh sides have pulled away from the frame, or the entire unit has shifted after wind shear. We’ve pulled starling nests from Olympia flues in East Meadow and Bethpage that blocked the flue entirely.
- The cap is visibly tilted, missing, or sitting in the yard after a storm. The mounting collar has fatigued, or the original installer used generic straps instead of Olympia’s bolt-down system. A cap held by pressure-fit straps will walk off eventually, guaranteed.
- Downdraft smoke spillage into the room that wasn’t there before. The cap’s baffle design has deformed from heat cycling, or the mesh is clogged with creosote flakes. Olympia’s rain guard is engineered to a specific height above the flue; if it’s sitting lower than spec, the draft physics change.
Replacement Cost & What’s Included
| Scope | Price Range |
|---|---|
| Olympia Chimney cap, standard single-flue (8″-13″) | $340-$480 |
| Multi-flue cap or custom size (OLM series) | $520-$680 |
| Crown repair/prep required before mounting | Add $180-$340 |
| Flue collar replacement if corroded | Add $120-$220 |
What drives the range: flue diameter, whether we need a ladder setup or full scaffolding for a steep colonial roof, and the condition of the crown beneath the old cap. We photograph everything before we quote. The price we agree to is the price on the invoice. Every cap installation carries our 90-Day Done Right Promise in writing, no arguing, and we register the manufacturer’s warranty on Olympia OEM parts.
DIY or Call Us?
There’s nothing here that will kill you, which is more than we can say for spring replacement. But there are two honest ways a homeowner gets this wrong. First, mismeasuring the flue and ordering a cap that sits crooked or blows off in the first nor’easter. Second, walking a steep roof with tools in hand without proper tie-off, which is how emergency rooms in Hicksville stay busy in October.
What you can safely check from the ground: whether the cap is present, level, and free of visible rust. What you should not attempt: removing a seized cap from a corroded collar, or drilling into a crown that may be structurally compromised. We’ve rescued more than one DIY job where the homeowner stripped the mounting bolts and cracked the crown trying to force the issue. Call (516) 259-3797 and we’ll give you a straight answer about whether this is a simple swap or something that needs eyes on it first.
FAQs
A quality 304 stainless cap lasts 15-20 years with normal exposure, but we’ve replaced caps after 8 years on homes within a mile of the LIRR where brake dust and road salt accelerate corrosion. Call (516) 259-3797 for an exact quote, estimates are free.
Sometimes. If the mesh is intact and only the mounting hardware has failed, we can fabricate new stainless brackets. But if the lid is deformed or the seams are splitting, replacement is the only permanent fix. We show you the photos and tell you which side of that line you’re on.
Most Olympia Chimney cap replacements take 45 minutes to 90 minutes from ladder set to cleanup, assuming the crown is sound and the flue collar doesn’t need work. If we find hidden corrosion, we’ll stop, photograph it, and give you a revised price before proceeding.
We carry the common OL single-flue sizes (8″, 10″, 13″) and select OLM multi-flue configurations on every service vehicle. Less common sizes or custom finishes, we can source within 24-48 hours. When you call (516) 259-3797, we’ll confirm stock against your model number so we’re not making two trips.

The chimney doesn’t care what you hoped it was - it shows you what it is. After 42 years on roofs in Hicksville and across Nassau County, we’ve learned to look at what it’s actually showing us, explain it plain, and fix it so you don’t have to think about it again.
