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 & Crown in Smithtown: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Smithtown, with most jobs completed in a single visit and upfront pricing agreed before we start. A standard Olympia Chimney cap replacement or crown repair typically runs $280-$650 depending on flue count and access, and we back every job with our 90-Day Done Right Promise in writing. This page is for homeowners who already have an Olympia Chimney system installed and need a cap that fits correctly, a crown that sheds water, or both - no guesswork, no manufacturer runaround. Call (631) 814-2057 to speak with a live person and book your free estimate.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 304 stainless single-flue caps: The mesh on these can salt-creep and weld itself shut after five to seven winters in Smithtown’s coastal air, especially homes within a few miles of the Nissequogue River. We see this every March when homeowners light the first fire and smoke backs into the room. We replace with a matching 304 cap or upgrade to 316L if you’re closer to the water, and we always verify the spark-arrestor clearance to OEM spec.
- Olympia Chimney multi-flue caps (the low-profile galvanized line): The galvanized skirt on these traps condensation where it meets the flue tile, accelerating rust at the corners. In Smithtown’s freeze-thaw cycles, that rust lifts the cap and creates a gap mice exploit. We pull the cap, grind back the corrosion, coat the base with a compatible primer, and reset with a proper bead of high-temp sealant - or recommend a full stainless upgrade if the metal is too far gone.
- Olympia Chimney wind-directional caps: The rotating collar seizes after a few seasons of Long Island pollen and coastal grit, leaving you with a fixed cap that no longer drafts properly on northeast winds. We disassemble the collar, clean the bushing, and lubricate with high-temp graphite - or source a replacement rotor if the bearing race is scored. Most homeowners don’t realize the cap has stopped rotating until we show them the wear pattern in the flue.
- Olympia Chimney crown wash (the factory sloped design): The factory slope is often too shallow for the wide eaves common on Smithtown’s 1960s-1980s split-levels, so water pools at the back edge and migrates through hairline cracks. We re-pitch with a Portland-based crown mix, add a drip edge, and sometimes extend the overhang an inch or two - whatever the specific roofline demands. Russell Haines learned this lesson on the older colonials near Caleb Smith State Park Preserve, where shallow crowns failed predictably every seven to ten years.
- Olympia Chimney chase covers on factory-built fireplaces: The stamped steel versions develop pinholes at the field bends after a decade of thermal cycling, and the factory caulk line at the flue opening dries to dust. We replace with a proper copper or stainless chase cover, soldered at the seams, with a cross-break that sheds snow load. The difference between a stamped cover and a fabricated one is about fifteen years of service life in Smithtown’s climate.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask for your Olympia Chimney model if you know it, the year of installation, and what you’re seeing - water, rust, smoke, animals, or draft issues.
- 2
Level-2 camera inspection. Our technician arrives in uniform, background-checked, and runs a camera up the flue before touching the cap or crown. You see the footage on a tablet. We document cracks, liner condition, and any blockage that would affect cap sizing or crown pitch.
- 3
Parts decision. If your cap is still in production, we quote OEM. If Olympia Chimney has discontinued the series, we source quality aftermarket from Gelco or Famco that matches the flue dimensions and draft requirements - never a universal clamp-on that fights the system. For crowns, we specify our Portland-based mix or a HeatShield crown coat depending on crack depth and substrate condition.
- 4
The repair. Most cap replacements take under two hours. Crown repairs or re-pours need a full day for proper cure time. We protect your roof and landscaping, work cleanly, and test the draft with a smoke pencil before we pack up.
- 5
Documentation and guarantee. You get photos of the finished work, a plain-English summary, and our 90-Day Done Right Promise in writing. If water gets past our crown or the cap doesn’t fit right, we come back. No paperwork to file, no arguing.
- 6
Cleanup and close. We haul away the old cap or crown debris, run a magnet for fasteners, and leave the driveway as we found it. The number on the estimate is the number on the invoice.

Why Smithtown Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been answering the phone with a live person for over 42 years, and we plan to be in Smithtown for thirty more. That changes how we treat a job. Our 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we make it right. Our technicians are background-checked, uniformed, and trained on Olympia Chimney’s specific flue dimensions, cap attachment methods, and common failure points. When Olympia Chimney parts are back-ordered or discontinued, we draw on our relationships with DuraFlex, HeatShield, Gelco, and Famco to source equivalents that fit and function correctly - not whatever’s in the van. Photos you can see, a plain-English verdict. Done right, and we stand behind it.
FAQs
No. As an independent Olympia Chimney service provider, we perform cap and crown work that does not affect the structural warranty on your flue or liner, provided we use compatible parts and proper installation methods. We document our work with photos in case you ever need to demonstrate maintenance compliance. Call (631) 814-2057 if you have warranty paperwork you’d like us to review.
Yes, in most cases. Olympia Chimney has discontinued some of their galvanized and lower-profile stainless lines, but we source dimensionally matched replacements from Gelco and Famco that fit the flue and maintain proper draft. We never install a universal cap that fights your system’s engineered airflow. Call (631) 814-2057 and we’ll confirm fit before we book.
Cracks under an eighth-inch wide with sound substrate get a professional crown coat. Anything deeper, spalled, or with exposed rebar needs a full rebuild - coating over failing concrete traps moisture and accelerates decay. We show you the camera footage and explain which category you’re in before you decide. Free estimates, no pressure.
Most single-flue replacements take ninety minutes to two hours. Multi-flue caps or jobs requiring roof access equipment may take half a day. We complete most jobs in a single visit because we confirm parts fit during the estimate, not after we arrive. Call (631) 814-2057 to schedule.
Water gets in. In Smithtown’s climate, that means freeze-thaw damage to the flue liner, rust on the damper, and eventually costly rebuild work. A failed crown also lets combustion gases leak into the chimney chase, which is a carbon monoxide risk we don’t treat lightly. The camera inspection tells you exactly where you stand - sometimes the news is good, and we’ll tell you that too. Call (631) 814-2057 for a free look.
