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.

AfterFast, Reliable Chimney Cap & Crown Across Quincy
Chimney cap and crown work in Quincy typically runs $280-$890 depending on whether we’re fitting a single-flue cap on a ranch in West Quincy or fabricating a custom multi-flue cover for a triple-decker near Wollaston station. Most of our Quincy appointments are scheduled within a week, and our crews dispatch from our Boston office with trucks stocked for the specific crown coatings and cap sizes we see in this market. Call (857) 597-5950 - a live person answers, 24 hours a day.
We’ve been working on Quincy chimneys long enough to know that a cap job here is rarely just a cap job. The triple-deckers around North Quincy, the brick two-families off Hancock Street, the condo-converted buildings in Quincy Center - these stacks were built for coal, converted to oil, and now vent gas or still burn oil through flues that share a single column. Our Chimney Cap & Crown team treats every Quincy call as a multi-flue inspection first, because that’s what the housing stock demands.
Why Hearthstone Chimney Co. Is Quincy’s Preferred Chimney Cap & Crown Company
We’ve served local communities for over 42 years, and Quincy has been part of our route since 1984. That’s four decades of learning which mortar mixes hold up against harbor air and which don’t, of measuring crowns on curved parapet walls you don’t see in newer construction, of explaining to condo boards why three units share one chimney and what that means for maintenance responsibility.
Our reputation here is built on documentation, not promises. Every Level-2 inspection ends with photos you can see and a plain-English verdict - documented like an engineer, explained like a craftsman. No recommendation for a liner, a rebuild, or even a cap replacement happens without camera evidence we show you on the spot.
The 90-Day Done Right Promise governs everything we do: Krafted right, Every time, Your home first, Standing behind it. In writing, no arguing. If it’s not right, we come back.
Calls are answered by a live person, 24/7 - not a voicemail, not a callback queue. Our background-checked, uniformed technicians complete most jobs in a single visit, with no-hassle upfront pricing so the number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Quincy
Cap Installation
New cap installation in Quincy runs $280-$550 for a standard single-flue stainless unit, but most of our calls here involve something more complex. On a triple-decker off Beale Street or a two-family near Quincy Center, we measure every flue in the stack, check clearances between them, and specify a cap that vents properly without cross-drafting. We install Gelco and Famco caps from stock, and we fabricate custom covers for odd-size flues or decorative pots we see on the pre-war stock.
Cap Replacement
Cap replacement is our most common Quincy service, and it’s rarely because the cap itself failed. Usually we find a rusted-through unit sitting on a cracked crown, or a cap that blew off in a nor’easter and was never replaced because the condo association couldn’t determine who owned the chimney. Replacement runs $320-$680 depending on whether we’re matching an existing multi-flue cover or upgrading from a failed single-flue to a proper full-width cap. We remove the old unit, inspect the crown beneath it, and document everything with photos before we quote.
Crown Repair
Crown repair in Quincy addresses the concrete or mortar wash that caps the chimney below the metal cap. On harbor-exposed homes in Squantum and Adams Shore, we’ve seen crowns deteriorate to exposed aggregate within eight to twelve years of a fresh pour - salt-laden air accelerates the damage significantly faster than in inland Milton or Randolph. Repair ranges from $450-$780 for crack filling and resurfacing, up to $1,200-$1,800 for full crown rebuilds on large multi-flue stacks. We never quote crown work without pulling the cap and inspecting what’s underneath.
Crown Coating
Crown coating is our preventive service for Quincy chimneys with sound structure but surface cracking or minor spalling. We apply Gelco CrownCoat, a flexible waterproofing membrane that bridges hairline cracks and sheds water without trapping moisture in the masonry. At $380-$620, it’s a fraction of rebuild cost and can add a decade of service life to a crown that’s otherwise sound. We recommend it heavily for Quincy Center and Wollaston buildings where the crown is original to the structure and replacement would require scaffolding or roof work.
Multi-Flue Cap
Multi-flue caps are essential Quincy equipment. Our one true local insight: a cap on a Wollaston or North Quincy triple-decker isn’t a roof accessory - it’s a multi-appliance draft and liner question, and any cap we install has to serve every flue in that stack at once. These run $580-$890 installed, with custom fabrication up to $1,400 for oversized or irregular configurations. We measure total crown width, flue spacing, and height clearances, then specify a cap with individual screening for each flue to prevent cross-contamination.
Custom Cap
Custom caps cover everything outside standard sizing: decorative clay pots on historic Quincy homes, curved parapet walls, or flue clusters too tight for off-the-shelf units. We fabricate in stainless or copper, with mesh sizing appropriate for your appliance type. Custom work starts around $720 and runs to $1,800 depending on metal gauge, finish, and installation complexity. Every custom order includes a template visit before fabrication.

Trusted Brands We Service in Quincy
We work exclusively with professional-grade materials - no builder-grade substitutes that fail in Quincy’s harbor climate. Our trucks carry Gelco crown coatings and Famco multi-flue caps from stock, and we source Olympia Chimney components for liner-related cap adaptations. This matters for turnaround: when a nor’easter tears the cap off your Squantum stack on a Saturday evening, we can often replace it Monday with a unit that fits, rather than ordering something that arrives next week wrong. The brands we use - HeatShield, Gelco, Olympia Chimney, Famco - are specified because they’ve held up in our documented Quincy installations, not because they’re cheapest.
Common Chimney Cap & Crown Problems We See in Quincy Homes
- Salt-laden harbor air destroys mortar joints and crown edges. In Squantum and Adams Shore, the persistent salt spray off Quincy Bay and Boston Harbor accelerates mortar erosion and efflorescence far faster than in inland South Shore towns. A cap that seals fine in Milton can sit on a Quincy crown that’s already crumbling within a decade of the last repoint.
- Triple-decker multi-flue columns create cascading failures. One cap covers three independent heating units in a single masonry stack. A single failed seam or lost fastener lets wind-driven nor’easter rain down the flue serving tenants on a different floor - and nobody realizes until the inspection.
- Condo-converted two-families have ambiguous chimney ownership. Caps go missing, crowns go unpainted for years, and nobody schedules maintenance because the association documents don’t clearly assign responsibility. Level-2 inspections on these buildings routinely turn up efflorescence and first-degree creosote nobody was tracking.
- Original crowns on pre-war stock are thin mortar washes, not structural concrete. These were never meant to last a century, and on buildings near Quincy Center they’re often the original 1920s construction. They crack, they spall, and they let water straight into the flue chase - but they look fine from the ground until you pull the cap and look.

What moves you within these ranges? Crown size and accessibility are the big ones. A walkable low-slope roof in West Quincy costs less than a steep slate roof in Wollaston. Multi-flue stacks require more material and more labor to fit properly. And we always inspect before we quote - the camera goes down every flue, the crown gets photographed with the cap off, and you see what we see before any number is final. Estimates are free. Call (857) 597-5950.

FAQs - Chimney Cap & Crown in Quincy
No. A single properly sized multi-flue cap covers all flues in the stack, with individual screened openings for each one. We measure the total crown width and flue spacing, then specify a cap that vents every unit without cross-drafting. On a recent job near Quincy Center, we pulled a corroded Famco cap off a 90-year-old multi-flue stack and ran a camera down all three flues: the first-floor oil unit’s clay tile was intact, but the second-floor flue showed spalling tile and the top flue had a water-stained smoke chamber from years of a missing cap. We installed a custom multi-flue cap sized to the crown, coated the cracked crown with Gelco, and gave each tenant a still-image report from the camera so nobody was sold a liner they didn’t need. Call (857) 597-5950 for an exact quote - estimates are free.
That’s efflorescence - salt crystallizing on the surface as moisture moves through the masonry and evaporates. On the Squantum Peninsula, where homes sit directly exposed to Boston Harbor on three sides, chimney mortar can show active spalling and salt-crystal efflorescence within a decade of a fresh repoint. It’s a failure rate technicians working even two miles inland in Quincy Center almost never see. The cap and crown are your first defense: a proper cap keeps rain out, and a coated crown keeps water from saturating the mortar beneath. We address efflorescence by fixing the water source, not just brushing off the crystals. Call (857) 597-5950 for an exact quote - estimates are free.
The crown is the concrete or mortar layer that seals the top of your chimney, sloped to shed water away from the flue. Coating it with a flexible membrane like Gelco CrownCoat bridges hairline cracks before they widen, and it’s especially valuable in Quincy where freeze-thaw cycles and salt exposure accelerate concrete deterioration. A coated crown on a sound base can outlast an uncoated one by ten years or more. We recommend crown coating for any Quincy chimney where the structure is sound but the surface shows early wear - it’s a square deal that prevents a bigger bill later. Call (857) 597-5950 for an exact quote - estimates are free.
The governing documents determine responsibility, but in practice, many Quincy condo conversions of two-family and three-family buildings have ambiguous language that leaves chimneys in limbo. Our role is documentation: we provide a Level-2 inspection report with photos of the cap, crown, and every flue, plus a plain-English summary of what needs attention and what can wait. That gives the board and the unit owners factual basis for deciding who pays. We’ve worked with associations throughout Quincy Center and Wollaston to establish maintenance schedules that prevent emergency repairs. Call (857) 597-5950 for an exact quote - estimates are free.
No. We recommend a liner only when camera inspection shows damage that affects safety - cracked tile, gaps between sections, or flaking that obstructs draft. Many Quincy chimneys with original clay tile are still functional, especially on oil units that run cooler than wood or gas. Our field vignette from Quincy Center illustrates this: three flues in one stack, three different conditions, and only one needed immediate attention. The others were documented and scheduled for monitoring. Nothing is recommended without camera evidence you can see for yourself. Call (857) 597-5950 for an exact quote - estimates are free.
