Call (857) 754-5607

We’ve been dispatching crews to Belmont from our Boston office for decades. We know the streets - Belmont Hill, Payson Road, the Colonial Revivals clustered around Concord Avenue - and we know what hides inside their chimneys. These aren’t generic suburban builds. They’re 80- to 130-year-old coal-era masonry stacks, often converted twice over (coal to oil, oil to gas), with flues that are oversized, sometimes shared, and frequently still unlined. That specific history changes what a cap and crown job actually needs to accomplish here.

Our Chimney Cap & Crown Services in Belmont

Cap Installation & Cap Replacement

A proper chimney cap in Belmont does more than keep rain out. On the shared and adjacent flues common in Belmont Hill and Payson Road neighborhoods, a correctly sized cap with proper mesh screening stops cross-drafting between neighboring appliances and blocks debris that can clog an already marginal flue. We install Gelco and Famco caps in galvanized, stainless, or copper finishes, measured on-site for your exact flue count and dimension. Replacement caps run $180-$340 for standard single-flue models; multi-flue systems start around $420.

Crown Repair

Belmont’s original crowns were often poured flush to the brick with no drip edge, a detail that matters enormously here. Eastern Massachusetts freeze-thaw cycles - dozens of swings above and below freezing each winter - pop those flat crowns apart, letting meltwater run straight down the brick face and wash out lime-mortar joints that are already 80 to 130 years old. Our crown rebuilds include a proper overhang, drip edge, and slope to shed water away from the masonry. A full crown rebuild in Belmont typically runs $680-$1,240 depending on accessibility and the extent of underlying brick repair needed.

Crown Coating

When the crown is structurally sound but cracked or porous, we apply HeatShield crown coating - a professional-grade refractory compound that seals hairline cracks and restores water resistance without the cost of full removal and repour. This is often the right call for Belmont chimneys where the crown damage is caught early, before freeze-thaw cycling has compromised the brick below. Crown coating runs $340-$580 and carries the same 90-Day Done Right Promise as our rebuilds.

Multi-Flue Cap & Custom Cap

On many Belmont Hill and Payson Road streets, our sweeps routinely open double-wythe brick chimneys with no tile liner at all - relics of pre-liner early-1900s construction that homeowners are still running modern gas boilers through, a code and safety gap endemic to this pocket of Belmont and far rarer in neighboring towns with more mixed or newer housing stock. These shared-stack situations demand multi-flue caps sized precisely for multiple flue terminals, with proper clearance and screening to prevent cross-contamination between units. We fabricate and install custom Famco multi-flue caps measured to your exact chimney top, typically $520-$890 installed.

On a Payson Road Colonial, our tech found a gas boiler venting into an unlined double-wythe stack - no liner, lime mortar joint washout, and a field of spalling brick at the crown - right beside the neighbor’s shared flue. We installed a stainless DuraFlex liner on the appliance flue, rebuilt the crown with a proper overhang and drip edge, and set a custom Famco multi-flue cap sized for both stacks. The homeowner’s draft stabilized, condensation staining stopped, and the neighbor’s water heater exhaust stopped sharing the migration path.

Trusted Brands We Service in Belmont

We stock professional-grade materials from Gelco, Famco, and Olympia Chimney on our service trucks, which means most Belmont cap and crown jobs don’t wait for parts. Gelco’s stainless caps carry a lifetime warranty against corrosion - a sensible choice for a town where road salt and freeze-thaw cycling are annual realities. Famco’s multi-flue systems are our go-to for the shared-flue configurations common on Belmont Hill. Olympia Chimney’s crown repair compounds bond reliably to aged lime-mortar substrates, which matters when we’re working on 1920s brick that won’t tolerate modern Portland-based patches. We don’t use builder-grade substitutes. The materials have to last as long as the masonry they’re protecting.

Common Chimney Cap & Crown Problems We See in Belmont Homes

• Spalling brick at the crown from freeze-thaw washout. Belmont’s original lime-mortar joints absorb moisture during thaw, then the next freeze expands that water and pops the brick face. The crown is supposed to stop this, but flat, cracked, or missing crowns let it continue. We see this most on homes near the top of Belmont Hill where wind-driven rain accelerates the cycle.
• Shared flue cross-contamination from missing or broken caps. In Belmont’s dense pre-WWII housing, a neighbor’s appliance venting into the same stack becomes a real problem when one side loses its cap. Carbon monoxide and exhaust gases migrate across. A proper multi-flue cap with integrated screening isolates each flue terminal.
• Condensation damage from oversized, unlined flues. Original coal-era chimneys converted to gas are often far too large for current BTU loads. Low-temperature exhaust condenses on the flue walls, runs down, and attacks mortar joints from the inside. The crown and cap show the first visible symptoms - staining, efflorescence, premature failure - while the liner deterioration continues unseen.
• Original crowns poured without drip edges. On Payson Road and surrounding streets, we regularly find crowns that were simply slopped on flush with the brick course. Water runs down the face instead of dripping clear. A rebuilt crown with a proper 2-inch overhang and drip groove solves this permanently.
