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 Flushing: What to Know First
A chimney cap and crown repair on an Olympia Chimney system in Flushing typically runs $285 to $780 for cap replacement and $450 to $1,400 for crown work, depending on flue size, crown condition, and whether the cap is stock or custom. Most Olympia Chimney cap and crown jobs are done in a single visit once parts are on hand; multi-flue custom caps add 5 to 7 business days for fabrication. We’re Level Two Chimney Flushing, an independent Olympia Chimney service provider, and we quote every cap and crown job in writing before any work starts.
This page is for homeowners in Flushing who already own an Olympia Chimney cap, crown, or liner system and want straight answers about what fails, what it costs to fix, and whether the work can wait. If you’d rather talk it through, call (516) 240-9191 and you’ll get a live person.
How Olympia Chimney Products Fail - and How We Fix Them
Olympia Chimney builds solid stainless and galvanized caps, but Flushing’s weather and the way attached older homes settle create a specific set of failure patterns. Here’s what we see most often, by line:
- Olympia Hi-Flo caps on masonry flues: wind-driven rain intrusion. The Hi-Flo’s high-open mesh screen is designed for strong draft, but on Flushing rowhouses with tight alley exposures, wind pushes rain sideways into the flue around the screen edges. Owners report damp fireboxes in spring. Fix: we retrofit the cap base with a sealed storm collar, or step to the Olympus HD line when the flue is consistently wind-loaded.
- Olympia Guardian single-flue caps: screen clogging from Flushing tree debris. Flushing’s older neighborhoods, particularly around Kissena Park and the Queens Botanical Garden side streets, drop a lot of leaf and seed material. Guardian caps have a fine mesh that clogs faster than coarser competitors. Symptom: fireplace starts smoking in late fall after years of clean burns. Fix: we clear the mesh, then recommend the larger-screen Guardian XL if the clog returns within a season.
- Olympia stainless-to-galvanized base corrosion at the mortar line. On Olympia caps with galvanized bases seated into a mortar crown, the galvanized rim rots where it contacts trapped moisture. This is common on Flushing homes with flat or low-slope roofs where crown drainage pools. The cap loosens and rattles. Fix: remove, inspect crown slope, rebuild drainage if needed, reseat cap with a stainless base and proper standoff.
- Crown spalling under Olympia multi-flue caps. Multi-flue caps are heavy. When the concrete crown underneath wasn’t poured with a proper drip edge, cap weight plus freeze-thaw cycles in Flushing crack the crown edges and the cap shifts. This is the failure most often missed by a visual-only inspection. Fix: camera the flue, then either seal and epoxy-fill the crown or rebuild it entirely with a cant strip before resetting the cap.
- Olympia custom-cap anchor failures on older brick. Corrine Halstead has pulled more than one custom Olympia cap from a Flushing Town Hall district chimney where the anchor bolts had pulled out of soft, century-old brick. The cap was fine; the anchoring was not. Fix: we reset the cap with masonry-rated anchors and a wider footplate, and we document the anchor points with photos before and after.
Our Olympia Chimney Chimney Cap & Crown Process

- 1
Call and book. A live person answers at (516) 240-9191, takes your address and the Olympia model if you know it, and schedules a visit.
- 2
Camera inspection first. We run a Level 2 camera scan down the flue before recommending anything. Corrine’s rule applies: the camera doesn’t negotiate - it just shows you what’s there. You see the footage before any quote is written.
- 3
Written scope and price. We identify cap-only, crown-only, or combined work. We source Olympia OEM when the warranty matters, and name-brand aftermarket (DuraFlex, HeatShield, Gelco) when the price matters more and performance is equivalent. You get the price in writing before we start.
- 4
Repair or replacement. Cap installs and crown coats usually take a few hours. Crown rebuilds take a day with proper cure time before the cap goes back.
- 5
Photo record delivered. You get before-and-after camera stills and a written note of exactly what was done. Clause 4 of the Haven Standard requires a photo record on every job. We’ve done it that way since 2009.
- 6
365-Day Done Right Promise. If the cap fails or the crown cracks within a year, we make it right at no charge.

AfterWhat Olympia Chimney Chimney Cap & Crown Costs in Flushing
Crown work is the bigger variable because it depends on how much of the concrete is salvageable. A thin crown crack sealed with elastomeric runs $450 to $650. A full crown rebuild under an Olympia multi-flue cap runs $900 to $1,400 in Flushing, more on a three-story walk-up with steep roof access. New stainless caps run $285 to $480 for a single flue, $520 to $780 for multi-flue stock sizes. Custom Olympia caps built to a specific Flushing rowhouse footprint add fabrication time and run $750 to $1,200. If a competitor has quoted you a written cap or crown estimate, bring it in - we do a free second opinion and we’ll match or beat it when the scope is honestly comparable.

Why Flushing Homeowners Call Level Two Chimney Flushing for Olympia Chimney Work

Most Flushing homes we service were built before 1960, and a lot of them carry chimneys that haven’t been properly documented in decades. We’ve inspected and cleaned more than 38,000 chimneys since 2009, every one with a written price before work started and a photo record when it was done. That’s not a tagline; it’s how we operate.
Our techs are background-checked and uniformed, and our license information is displayed on every page. When an Olympia cap or crown needs parts we don’t stock, we source through our multi-brand network - DuraFlex, HeatShield, Gelco - so you’re never stuck waiting on one distributor. And if we find something that can safely wait a season, we’ll tell you that in writing and tell you why. Corrine grew up in Queens and has spent nearly two decades doing chimney work across the borough, including older attached homes near the Flushing Town Hall district where the brick and mortar tell a story all their own.
FAQs
No, as long as the replacement cap is sized to the original flue opening and installed without modifying the liner or crown beyond manufacturer spec. We keep Olympia OEM on hand for warranty-relevant jobs and document every install with photos so you have a record if a claim ever comes up.
If the mesh is clogged but the cap body, base, and anchor points are intact, a cleaning usually solves the problem for $150 to $225 in Flushing. If the base is corroded, the mesh is separating from the rim, or the cap rocks when you press it, replacement is the honest call. We’ll show you the camera footage before we quote either way.
Stock single-flue caps are usually on our truck or available within 2 to 3 business days. Custom multi-flue Olympia caps take 5 to 7 business days to fabricate. Crown coatings use material we carry regularly, so those can often be done the same visit as the inspection.
Yes, if the cap is still sound and the crown damage is limited to surface cracking or minor edge spalling. We seal, coat, or rebuild the crown as needed and reset the existing cap with new anchors. If the cap base is part of the problem, we’ll tell you plainly and show you why in the photos.
Water keeps getting into the masonry, freeze-thaw cycles in Flushing widen the crack, and eventually the crown edges break away and the cap loses its seat. The repair bill goes from hundreds to over a thousand when the crown has to be fully rebuilt. Call (516) 240-9191 and we’ll assess it before it gets there.
