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 Danbury: What to Know First
As an independent Olympia Chimney service provider, we install, replace, and repair chimney caps and crowns on Olympia Chimney systems throughout Danbury and Fairfield County. Most Olympia Chimney cap and crown jobs are completed in a single visit, with upfront pricing agreed before we start. We do not sell what you do not need, and we document every recommendation with camera photos you can see for yourself.
This page is for homeowners in Danbury who have an Olympia Chimney cap showing rust-through, a crown with hairline cracks spreading after last winter’s freeze cycles, or water staining on the ceiling below the chimney. If that sounds like your situation, call us at (475) 375-9457. A live person answers, day or night.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney 304 stainless single-flue caps in the GCC series develop crevice corrosion at the welded corners where the lid meets the skirt, especially on homes near Lake Candlewood where salt-laden air accelerates the attack. The weld bead traps moisture, and once rust starts, it works inward faster than it shows on the surface. We pull the cap, assess the flue tile condition underneath, and replace with either an Olympia Chimney OEM equivalent or a Gelco cap with fully hemmed seams if the homeowner wants longer service life.
- Olympia Chimney multi-flue caps in the MCC line sag at the center support bar when installed on wider masonry chimneys common in Danbury’s 1960s-1980s colonials. The factory 16-gauge crossbar flexes over seasons of thermal cycling, and the mesh sides bow outward, creating gaps for squirrels and rain. We reinforce with a custom-fabricated 14-gauge support or spec a Copperfield multi-flue cap with a heavier top-frame if the flue layout allows.
- Olympia Chimney wind-directional caps (the RotoTop series) seize in the bearings after five to seven years of Fairfield County pollen and fine ash buildup. The turbine stops spinning, which defeats the draft-assist function and can actually back-puff smoke during low-fire conditions. We disassemble, clean the bearing race with a non-residue solvent, and if the housing is scored, we source a replacement rotor assembly rather than selling the homeowner a whole new cap.
- Olympia Chimney crown wash systems, particularly the pre-mixed cementitious coatings applied at original installation, shrink-check within three to four years on south-facing chimneys in Danbury. The thermal load from summer sun on black flue pipe accelerates the curing stress. We grind back to sound concrete, apply a bonding agent, and re-coat with HeatShield CrownCoat or a poured concrete crown if the structural integrity is compromised. We never skim-coat over active cracks.
- Olympia Chimney chase covers on factory-built chimneys - the galvanized models, not the stainless upgrades - rust from the underside where condensation drips off the flue pipe and pools at the pan edge. By the time the homeowner sees staining on the siding, the pan has pinholes. We replace with a Gelco or Copperfield .032 aluminum or 304 stainless chase cover, properly counter-flashed, and we always verify the Olympia Chimney flue termination height meets clearance before buttoning up.
Our Olympia Chimney Chimney Cap & Crown Process
- 1
Call and schedule. A live person answers, 24 hours a day. We ask what you’re seeing - water, rust, animals, draft problems - and book a time that works. No deposit, no pressure.
- 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. We explain what we find in plain English, not scare tactics.
- 3
Parts decision. If the cap is salvageable, we say so. If replacement is needed, we present options: Olympia Chimney OEM if warranty coverage is a concern, or professional-grade aftermarket from Gelco or Copperfield if the geometry or budget favors it. You choose.
- 4
The repair. For crown work, we cut back to sound substrate, build forms if needed, and pour or coat. For cap replacement, we verify flue tile dimensions to the sixteenth - Olympia Chimney specs can vary by production year - and secure with proper fasteners, not sheet-metal screws that strip.
- 5
Test and document. We run the camera again after crown coating cures, or verify cap fit with a smoke pellet test. Photos go in your file. The invoice matches the estimate.
- 6
Cleanup and guarantee. We haul away old material. Your work is covered by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we make it right.

Why Danbury Homeowners Call Hearthstone Chimney Co. for Olympia Chimney Work
We’ve been answering calls in Fairfield County for over 42 years, and we’ve learned that homeowners who’ve been burned once want three things: someone who shows up when they say, someone who explains the problem without inventing urgency, and someone who’ll still be in business if something needs tweaking.
Our technicians know Olympia Chimney products specifically - the GCC, MCC, and RotoTop lines, the crown wash formulations, the chase cover profiles. When a part is discontinued or back-ordered, we have working relationships with Gelco, Copperfield, and Famco to source equivalents that fit and function correctly. We’re not locked to one catalog.
Every job carries the 90-Day Done Right Promise - Krafted right, Every time, Your home first, Standing behind it. In writing. No paperwork to dig up, no arguing. And a live person answers the phone, 24 hours a day, 7 days a week. That’s not a marketing claim. That’s how we’ve operated since 1984.
Russell Haines puts it this way: “Tell me what you’re seeing, and I’ll tell you what it actually means.” That’s the approach we bring to every Olympia Chimney cap and crown job in Danbury.
FAQs
No - independent service does not void your Olympia Chimney product warranty, provided the repair uses compatible parts and follows standard installation practices. As an independent Olympia Chimney service provider, we document our work with photos and part numbers so warranty questions are straightforward if they ever arise. If warranty coverage is critical to you, we can source OEM Olympia Chimney caps rather than aftermarket equivalents. Call (475) 375-9457 to discuss your situation.
304 stainless Olympia Chimney caps last 12 to 18 years in Fairfield County with normal maintenance; galvanized or lower-grade models often show failure in 5 to 8 years, especially within a few miles of salt water or on homes with wood-burning inserts that produce more acidic condensation. The freeze-thaw cycles we get on Clapboard Ridge and other elevated Danbury neighborhoods accelerate crown deterioration regardless of cap quality. A Level-2 inspection every two to three years catches problems before they spread.
Yes - we maintain dimensional records and cross-reference Olympia Chimney legacy part numbers with current Gelco, Copperfield, and Famco catalogs. In most cases we can fabricate or source a functional equivalent that fits your flue tile and maintains proper clearance. For unusual configurations, we can have a custom cap fabricated from .024 stainless or .032 aluminum with a two-week lead time.
Crown coating with HeatShield CrownCoat is sufficient when the underlying concrete is structurally sound - no exposed rebar, no through-cracks wider than a sixteenth inch, and no spalling deeper than a quarter inch. We verify this with sounding and camera inspection. If the crown is cracked through to the flue gases, or if the concrete has lost more than 30 percent of its thickness, we recommend a formed, poured rebuild. We show you the photos and explain which category you’re in. No guesswork, no upsell.
We book inspections within a few business days, and most cap replacements and crown coatings are completed in a single visit once scheduled. Crown rebuilds require a return trip after the concrete cures, typically three to five days. We do not promise same-day dispatch - we promise we’ll be there when we say, with the right parts and the time to do the job properly. Call (475) 375-9457 to get on the schedule.
