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 Leominster: What to Know First
We provide independent Olympia Chimney chimney cap and crown service in Leominster, with most jobs quoted and scheduled within 24 hours of your call. A standard cap replacement runs $280-$520 installed; crown repair or coating typically falls between $340-$780 depending on accessibility and the extent of water damage beneath. Every quote is written, itemized, and agreed to before our tech sets a ladder on your roof - that’s Haven Standard Clause 1, and it’s how we’ve operated since 2009.
This page is for Olympia Chimney owners in Leominster and nearby towns who need cap or crown work and want to know what it costs, what parts fit, and whether their warranty stays intact. Corrine Halstead and our crew have handled Olympia Chimney systems across central Massachusetts for years, including the multi-flue setups common in the older homes near Monument Square. Call (978) 481-2900 for a free estimate, or read on for the specifics.
How Olympia Chimney Products Fail - and How We Fix Them
- Olympia Chimney Gelco-style single-flue caps in the 13″ x 13″ and 8″ x 17″ sizes develop corner-seam separation after 6-10 Leominster winters. The 304 stainless holds up, but the spot-welded corners trap freeze-thaw moisture from our wet March-April cycles. We replace with a Gelco equivalent from our Haven buying network or fabricate a custom cap with fully welded seams and a drip edge that extends past the flue tile.
- The Olympia Chimney multi-flue cap line with integrated screen suffers screen sag on south-facing chimneys in Leominster’s summer humidity. The mesh loosens at the crimp points, creating gaps that let squirrels and starlings nest. We remove the cap, assess whether the screen is field-replaceable (some 2018-2021 lots are not), and either re-screen with heavier 18-gauge mesh or source a direct-fit aftermarket cap from Famco that maintains the same exterior dimensions.
- Olympia Chimney’s standard concrete crown pours on pre-2015 installations lack the polymer modifier that later specs added. In Leominster, that means the crown surface starts spalling - flaking in thin sheets - after the first decade, especially where roof runoff from ice dams pools against the chimney shoulder. We grind back to sound concrete, apply a bonding agent, and pour a modified crown sloped at 3:12 minimum, or coat with HeatShield CrownCoat if the substrate is too thin to rebuild.
- The Olympia Chimney “slip-in” cap with exterior clamp band loosens on terracotta flue tiles that have minor surface erosion. The clamp bites into soft tile, the cap tilts, and water runs directly into the flue. We find this on Leominster’s 1920s-1950s housing stock where the original flue liners are still in service. Our fix: a cap with an interior leg kit that bears on the flue walls below the erosion zone, or a flue-top damper cap from Olympia’s current catalog if the tile crown is intact enough to support it.
- Olympia Chimney crown wash applications on factory-built chimney systems crack at the chase cover joint because the metal expansion rate differs from the concrete overlay. The chase cover lifts slightly each heating season, the wash separates, and water enters the chase cavity. We remove the failed wash, install a proper chase cover with cross-break and drip edge, and only then apply a flexible crown coating rated for the temperature swing.
Our Olympia Chimney Chimney Cap & Crown Process

- 1
Call and schedule. A live person answers. We ask for the Olympia Chimney model or series if you know it, the approximate chimney age, and what you’re seeing - water in the firebox, rust stains on the brick, animal noise, visible cap tilt. We book a 2-hour arrival window.
- 2
Camera-first inspection. The camera goes up first. Everything else follows the footage. Corrine or a trained tech runs a full NFPA 211 Level 2 scan: flue liner condition, smoke chamber, firebox, and the exterior crown and cap from roof level. Photos are time-stamped and stored to your job record under Haven Standard Clause 4.
- 3
Written price on site. Before any tool leaves the van, you get a line-item quote: cap or crown work, any flue repair found, materials specified by brand and part number. No verbal estimates. No “we’ll figure it out as we go.”
- 4
Parts decision with you. If your cap is still under Olympia Chimney’s 20-year limited warranty, we explain what OEM replacement preserves it versus what quality aftermarket options from our DuraFlex, Gelco, or Famco stock cost. You choose; we document the choice.
- 5
Repair and test. Cap jobs include a water test with a hose from ground level, checking for leaks at the flue joint. Crown rebuilds get a 48-hour cure before we return for a follow-up photo if the weather’s below 50°F. Every job ends with a second camera run to confirm flue integrity.
- 6
Documentation and guarantee. You receive the photo record, the written scope, and the written warranty. The 365-Day Done Right Promise applies from day one. If water gets past our cap or crown work in year one, we return and fix it.

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

We’ve inspected and cleaned more than 38,000 chimneys since 2009, and a notable share of the cap and crown calls in Leominster involve Olympia Chimney products - partly because the brand sold heavily in New England during the 2010s building boom, and partly because our climate exposes the gaps between good-enough design and what actually lasts here.
Corrine Halstead and our techs know the difference between an Olympia Chimney cap that failed from defect and one that failed from installation error, and we document which it is so you’re not paying for someone else’s mistake. When Olympia parts are back-ordered - the multi-flue line had a 6-week gap in late 2023 - we have DuraFlex, HeatShield, and Gelco equivalents in our Haven buying network that meet or exceed OEM spec, and we’ll show you the comparison in writing before you decide.
Background-checked, uniformed technicians. License number on every page. A text when your tech is en route. And the 365-Day Done Right Promise stamped on every job. That’s the Haven Standard, and it’s how we work in Leominster.
FAQs
No, if the work is performed correctly and documented. Olympia Chimney’s limited warranty covers manufacturing defects, not installation. As an independent Olympia Chimney service provider, we use OEM or equivalent parts and photograph the before condition so any future warranty claim has a dated baseline. If your cap failed from a known defect in a specific lot, we note that in your job record and guide you on the warranty process. Call (978) 481-2900 and we’ll check your install date against known service bulletins.
Most single-flue cap replacements are complete in 90 minutes to 2 hours, including the camera inspection and water test. Multi-flue caps or jobs requiring chase cover removal take 3-4 hours. Crown rebuilds need a full day plus a 48-hour cure before we consider the job closed. We book the time your job actually needs, not a rushed window that leaves water testing undone.
We can coat and seal a crown with surface spalling and cracks under 1/4 inch using HeatShield CrownCoat or equivalent. If the concrete is crumbling at depth, exposing the chimney brick beneath, or if the crown has lost its slope and is holding water, we rebuild. The camera inspection and a physical probe tell us which within 10 minutes of being on your roof. You’ll see the photo and get both options priced before we start.
The cap may be 430 stainless - magnetic and less corrosion-resistant than 304 - or the hardware may be galvanized steel that rusts faster than the cap body. Olympia Chimney used both grades depending on the series and year. We check with a magnet on site; if it’s 430 or mixed hardware, we quote a full 304 replacement with stainless fasteners. The price difference is usually $40-$80 and it solves the cycle of rust stains you’re seeing.
Not automatically. A failed cap or crown lets water into the flue, which can damage the liner over time, but we camera-scan to confirm liner condition before recommending anything. In Leominster’s older homes near Monument Square, we’ve found clay liners that have handled minor water intrusion for decades without structural loss, and we’ve found stainless liners with hidden joint separation that need attention. The camera shows which you have. No liner work is quoted without photo evidence you can see for yourself. Call (978) 481-2900 to schedule - estimates are free.
