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 Downingtown: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Downingtown, typically completing standard cap replacements within one visit and crown repairs within two business days. Every job starts with a written price before any work begins - no exceptions - and includes our camera-scan inspection with a documented photo record under Haven Standard Clause 4. Olympia Chimney caps and crowns hold up well in Chester County’s freeze-thaw cycle, but we’ve found their standard galvanized caps on the Builder Series can rust through at the seams faster than owners expect when roof runoff pools behind the chimney. This page is for homeowners who need to know what failed, what it costs, and whether the fix can wait. Call us at (484) 558-2798 for a free estimate, or bring us a competitor’s written quote for our free second opinion.
How Olympia Chimney Products Fail - and How We Fix Them
- Builder Series galvanized cap seam separation. The entry-level galvanized caps on Olympia Chimney’s Builder Series use a rolled seam at the lid joint that traps moisture from Downingtown’s spring rains and winter freeze-thaw. We see this open up after 6-10 years, not the 15-20 owners expect. We replace with a stainless steel cap from our Haven buying network or an Olympia Chimney stainless upgrade if the flue size demands it - the seam is welded, not rolled, and carries our 365-Day Done Right Promise.
- ProCap multi-flue cap undersizing on pre-1980 chimneys. Olympia Chimney’s ProCap line is spec’d for modern flue dimensions, but Downingtown’s East Brandywine corridor colonials and 1920s twins often have oversize flue tiles or multiple flues clustered tighter than current code allows. We measure with a tape, not a guess, and fabricate custom multi-flue caps through our Copperfield supply when stock ProCap dimensions would leave gaps that draw rain.
- ChimneySaver crown coating delamination on poured concrete crowns. Olympia Chimney’s ChimneySaver elastomeric crown coating works when applied to clean, sound concrete, but we’ve found it peels in sheets when applied over hairline cracks that weren’t routed first - a shortcut we see from painters who got into chimneys. We grind cracks to 1/4-inch depth, fill with HeatShield CrownSeal, then topcoat. The camera doesn’t guess. Neither do we.
- Chimney Crown FormaKit corner cracking in zero-lot-line homes. The FormaKit pre-formed crown system saves labor on new construction, but the corner segments lack reinforcement for the thermal stress of a Downingtown summer sun-to-winter freeze cycle. We see radial cracks at the corners after 3-5 years. Our fix: remove the FormaKit, pour a reinforced concrete crown with proper overhang and drip edge, then seal with Gelco CrownCoat.
- Spark arrestor mesh clogging on homes with Bradford pear or locust trees. Olympia Chimney’s standard 5/8-inch mesh spark arrestor meets code, but in Downingtown neighborhoods with mature landscaping - especially near Kerr Park and the borough’s older sections - seed pods and leaf debris pack the mesh by mid-October. We upgrade to a 3/4-inch mesh with a raised hood design that sheds debris, or install a Gelco cap with a built-in debris skirt if the flue configuration allows.

These are real Downingtown prices for work done under the Haven Standard - not teaser rates that balloon on site. A rusted Builder Series cap that’s dripping into the flue doesn’t get cheaper if you wait. Call (484) 558-2798 for your exact written price; estimates are free.
Why Downingtown Homeowners Call Level Two Chimney Downingtown for Olympia Chimney Work

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and we’ve learned that brand loyalty means nothing if the tech can’t name what’s wrong. Corrine trained in building trades and HVAC at SUNY Westchester before working flues from the ground up, and our crew knows Olympia Chimney’s product lines well enough to spot when a Builder Series cap is three seasons from failure versus three years. We’re independently owned and operated - not a franchise, not affiliated with Olympia Chimney - which means we source from DuraFlex, HeatShield, Gelco, and Famco through our Haven buying network when that’s the better part for your flue. Every job gets a written price first, a photo record last, and the 365-Day Done Right Promise in between.
FAQs
No - installing a third-party cap or having crown work done by an independent technician does not void the original product warranty on an Olympia Chimney flue liner or manufactured component, provided the work doesn’t damage those components. We document our work with photos specifically to protect your warranty position. If you have a current Olympia Chimney warranty claim in progress, call us at (484) 558-2798 and we’ll coordinate our scope to avoid complications.
We source both. Olympia Chimney stainless caps and ProCap multi-flue units come through our Haven buying network when dimensions and lead times work for your job. When OEM stock is backordered - we’ve seen 3-4 week delays on custom ProCap sizes - we spec equivalent stainless from Gelco or Famco with matching gauge and mesh ratings. We write down which part we’re using and why before you sign.
We camera-scan and photograph the crown from the roof and from inside the flue looking up. Hairline cracks with intact concrete and no spalling (surface flaking) get routed, sealed, and coated. Spalling deeper than 1/2 inch, exposed rebar, or a crown that slopes toward the flue instead of away from it means rebuild. We show you the photo and explain which category you’re in before quoting.
Most single-flue stainless cap replacements are complete in 45-90 minutes on site, including the post-work camera verification. Multi-flue ProCap or custom fabrications run 2-4 hours. Crown rebuilds span two visits: demo and forming on day one, pour and cure with return for sealing within 48 hours. We don’t rush cure times - a green crown cracks by spring in Downingtown’s freeze-thaw.
Water enters the flue, degrades the flue liner, rusts the damper, and stains the firebox. In Downingtown’s climate, we’ve seen unprotected flues develop Class III glazed creosote faster due to moisture cycling, and spalling brickwork from freeze-thaw damage to saturated masonry. Carbon monoxide risk rises if the liner deteriorates enough to allow flue gas leakage. The repair cost doesn’t go down with waiting. Call (484) 558-2798 for a free estimate and we’ll show you exactly what your camera footage reveals.
