Call (857) 392-4709

We’ve been working on Brookline chimneys for over 42 years. We know the Queen Anne Victorians around Coolidge Corner with their three-flue stacks, the Edwardian apartment blocks near Washington Square whose crowns have taken a century of nor’easter punishment, and the converted condos on Fisher Hill where one chimney now serves four separate unit owners. If your cap is rusted through or your crown is spalling, water is getting into your masonry. In Brookline’s coastal New England climate, that freeze-thaw damage accelerates every winter. Call us at (857) 392-4709. A live person answers, 24 hours a day.

Our Chimney Cap & Crown Services in Brookline

Cap Installation

New cap installation on a Brookline chimney starts with measuring the flue or flues correctly - and on these 1880s-1920s multi-flue stacks, that is rarely straightforward. A single oversized masonry chimney might vent a basement boiler, a first-floor fireplace, and a second-floor gas insert, each with different flue diameters and draft requirements. We size and install stainless steel, copper, or galvanized caps from Gelco and Copperfield with proper clearances and screening to keep out squirrels, raccoons, and the wet, heavy snow that Brookline nor’easters drive sideways. Every installation includes a camera inspection of the flue interior before we seal the cap, so you know the stack is sound underneath.

Cap Replacement

Cap replacement is one of the most common calls we get in Brookline, and it is rarely just the cap. The original cap rusted because water was pooling on the crown beneath it, or because the flue gas condensation from a modern low-BTU appliance was eating the metal from the inside out. We remove the old cap, inspect the crown and flue top for hidden damage, then install a replacement sized to the actual flue - not the closest stock size from a hardware store. For condo-converted mansions near Coolidge Corner, we coordinate with multiple unit owners when one chimney serves separate apartments, and we pull the Brookline permit so the work is documented for the next sale.

Crown Repair

Crown repair on Brookline’s century-old chimneys often means rebuilding what is left after decades of freeze-thaw damage. The soft historic brick and lime mortar common in pre-1920 construction absorbs water, expands in winter, and cracks the crown from below. We cut back the damaged concrete or mortar crown, form a new cast crown with proper slope and overhang to shed water away from the masonry, and seal the edge with through-wall flashing where needed. On a three-flue 1905 brick stack off Fisher Hill, our crew found the original terra-cotta flue liners intact but the crown badly spalled from decades of freeze-thaw, with a rusted Famco cap that had been letting nor’easter snow straight into the smoke chamber. We poured a new cast crown with a proper overhang, set a custom multi-flue copper cap sized to the two fireplace flues and the gas insert flue, and sealed the flashing, then filed the Brookline building permit and passed inspection before the seller’s closing.

Crown Coating

Crown coating is a preventive option for Brookline chimneys where the crown is cracked but structurally sound - usually early-stage spalling on a 1960s-1980s concrete crown, or a well-built original that has developed hairline cracks from thermal cycling. We apply a flexible, breathable crown sealant formulated for New England temperature swings, not the hardware-store paint that traps moisture and accelerates damage. Crown coating buys time on a sound crown. It does not fix structural failure. We will tell you which one you have, with photos, before we quote the work.

Multi-Flue Cap

Multi-flue caps are essential on Brookline’s large Victorian and Edwardian chimneys, where a single masonry stack vents two, three, or four separate appliances. Off-the-shelf single-flue caps bolted onto these oversized structures leak at the seams, rust out within a few nor’easters, and let wet snow into every flue on the stack. We fabricate and install multi-flue caps as a single hooded unit, sized to cover all flues with one continuous slope that sheds water and snow clear of the masonry. For condo-converted properties, this also simplifies maintenance - one cap, one crown, one point of weather protection for a chimney that legally spans multiple owners.

Custom Cap

Custom caps solve the problems that stock caps cannot. Irregular flue spacing on a decorative chimney pot, a historic copper finial that must be preserved, or a gas vent terminal that needs integrated screening - we measure, fabricate, and install caps that fit the chimney you actually have, not the one in a catalog. In Brookline’s historic districts, custom work preserves the architectural character that makes these houses worth maintaining.

Trusted Brands We Service in Brookline

We work exclusively with professional-grade materials from brands that have proven themselves in New England conditions: Copperfield for stainless and copper caps, Gelco for multi-flue and custom-fabricated solutions, and Famco for vent terminals and specialty screening. We stock common sizes and fabrication specs for Brookline’s typical flue dimensions on our trucks, so most cap replacements do not wait on parts. For custom work, we send measurements to our fabricator and typically have the cap within a week. No builder-grade substitutes. The cap that goes on your chimney is the same grade we would put on our own.

Common Chimney Cap & Crown Problems We See in Brookline Homes

• Spalled crowns from freeze-thaw cycling. Brookline’s coastal climate delivers wet snow followed by hard freeze repeatedly through winter. Water penetrates the crown concrete, expands, and flakes off the surface layer. By spring, the crown is cratered and funneling water straight into the masonry core. Annual post-winter inspection catches this before the stack needs rebuild.
• Rusted single-flue caps on multi-flue chimneys. A previous owner bolted a stock cap onto one flue of a three-flue stack and called it done. Snow blows around the cap, into the open flues, and through the smoke chambers. We replace these with proper multi-flue caps sized to the full chimney top.
• Condensation damage behind terra-cotta liners. Original 1880s-1920s flue liners on Coolidge Corner and Washington Square stacks crack and spall after a century of freeze-thaw. Draft fails. Acidic condensation from modern gas appliances eats the mortar joints behind the liner. The cap and crown look fine from the ground, but the flue is deteriorating inside. Camera inspection reveals what eyes cannot.
• Condo authorization gridlock. A single shared chimney in a converted mansion spans separately owned units. One owner sees water damage and wants the crown replaced. Another does not want the expense. A third is selling next month and needs the permit for closing. We have worked with Brookline condo associations and individual owners to structure cap and crown jobs that satisfy all parties and comply with the town’s permitting requirements.
