Why Hearthstone Chimney Co. Is Everett’s Preferred Chimney Cap & Crown Company

We’ve been serving the dense inner-ring communities around Boston for over 42 years, and Everett’s triple-decker housing stock is some of the most specialized chimney work we handle. Our technicians have documented hundreds of inspections in Everett neighborhoods from Woodlawn to the Highlands, and we’ve learned to spot the cross-flue contamination that only happens in shared-stack buildings.

Our Chimney Cap & Crown team carries the 90-Day Done Right Promise on every job - in writing, no arguing. If the cap doesn’t seal or the coating fails, we come back and make it right. That matters in Everett, where a cap installed wrong doesn’t just leak into your unit; it can wick moisture into your neighbour’s flue through century-old mortar joints.

Calls are answered by a live person 24 hours a day, 7 days a week - not a voicemail system, not a callback queue. Background-checked, uniformed technicians arrive when we say they will, and most cap and crown jobs are completed in a single visit with no-hassle upfront pricing. The number on your estimate is the number on your invoice.

Our Chimney Cap & Crown Services in Everett

Multi-Flue Cap Installation

Everett’s triple-deckers and attached two-families almost always share a single multi-flue brick stack between units that may be under different ownership. A missing or rusted-through cap on one flue lets salt-laden Mystic River air and rain wick sideways through deteriorated mortar joints into the neighbour’s flue, and vice versa. In most neighbouring suburbs each dwelling has its own separate stack, which is why cross-contamination between units is a distinctively Everett diagnosis. We measure every flue opening on your shared stack and install a custom multi-flue cap that seals each flue independently, with screened vents where active and solid covers where decommissioned. Our caps come from Copperfield and Famco, sized to your exact chimney top.

Custom Cap Fabrication

Standard big-box caps don’t fit Everett’s irregular chimney profiles. Many triple-decker stacks were built with slightly different flue spacing than the plans called for, or they’ve settled over 100+ years so the crown slopes unpredictably. We fabricate custom caps in stainless steel or copper to match your exact dimensions, with proper overhang to shed water away from the crown edge. On a triple-decker off Broadway near the Mystic River, we found the second-floor unit’s flue wide open with no cap while the first-floor gas furnace had been converted to a side-wall vent years earlier - the original flue was left unlined and uncapped, drawing harbor moisture straight through the shared brick stack. Our tech installed a custom multi-flue cap from Copperfield across both active openings and coated a spalling crown with Gelco, and the third-floor owner’s draft and odour complaints stopped within a week.

Crown Repair & Coating

The crown is the concrete slab that seals the top of your chimney between the flue tiles. In Everett, crowns spall faster than inland because salt spray from Boston Harbor accelerates mortar joint erosion, and the freeze-thaw cycle opens cracks that let water saturate the brick below. We grind out deteriorated crown material, apply a bonding agent, and coat with Gelco or HeatShield crown coating - a flexible, waterproof membrane that bridges hairline cracks and sheds water even when the substrate moves slightly. For crowns with significant spalling, we may need to pour new concrete with proper slope and drip edge. Either way, you’ll see photos before and after, and we’ll tell you plainly whether the crown can be coated or needs rebuilding.

Cap Replacement

Sometimes the crown is sound but the cap itself has failed - galvanized steel rusted through, mesh collapsed from ice load, or blown off in a nor’easter. We replace with stainless steel or copper caps from Olympia Chimney or Famco, with proper screening to keep out squirrels and raccoons without clogging with creosote. In Everett’s dense neighbourhoods, animals travel roof-to-roof easily; a missing cap is an open invitation. We check the flue tile condition while we’re up there, and if we find a decommissioned flue that’s been left open, we’ll recommend sealing it properly as part of our Fireplace Services in Everett.

Trusted Brands We Service in Everett

We don’t use builder-grade substitutes. For Everett’s harsh coastal-exposure conditions, we specify professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - brands that stand up to salt-laden air and freeze-thaw cycling. We stock common cap sizes and crown coating materials locally, so most Everett jobs don’t wait on parts. If your triple-decker needs a custom fabrication, we measure on-site and typically have it within a few business days. The materials cost more than hardware-store alternatives. They last longer, seal better, and they’re what we put on our own Chimney Cap & Crown in Everett properties.

Common Chimney Cap & Crown Problems We See in Everett Homes

• Neighbour’s flue left uncapped after gas conversion. Rain and salt air travel laterally through cracked mortar joints into the adjacent unit’s flue. We find this constantly in Everett condo conversions where one unit updated their heating system and nobody told the others the flue was now open to the weather.
• Original coal-era crown spalling from salt exposure. Everett sits along the Mystic River with exposure to salt-laden air from Boston Harbor, accelerating mortar joint erosion and spalling on exterior chimney masonry faster than inland communities at the same latitude. Combined with the standard New England freeze-thaw cycle, chimneys here typically show crown and joint deterioration at shorter intervals than comparable structures in MetroWest or the Route 128 belt.
• Multi-flue chimney with mismatched appliance flues. One gas, one oil, one decommissioned - a single generic cap can’t seal all three properly, leaving the abandoned flue open to animals and weather while the active flues don’t draft correctly.
• Roof access complications on tight Everett streets. Ladders can’t always angle safely against triple-deckers with shallow front yards or overhead wires. Our crews carry specialized ladder configurations and, when necessary, coordinate bucket truck access for crown work on taller stacks.
