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 Brookline
In Brookline, a broken chimney cap or a crumbling crown is rarely a one-flue problem. Most of the borough’s housing stock runs on shared masonry stacks serving multiple units, which means a failed crown on one side can quietly compromise the draft, air quality, and safety of the neighbor on the other. Top Hat Chimney has been inspecting, repairing, and rebuilding caps and crowns across Brookline for over 29 years, and we understand the borough’s signature hazard better than any national outfit that rolled in last spring. Call (781) 277-4630 and you’ll get Wendell or one of his crew, a straight answer on what’s actually wrong, and a price before a single tool comes off the truck.
Why Top Hat Chimney Is Brookline’s Preferred Chimney Cap & Crown Company
We’ve worked the streets of Brookline long enough to know that no two stacks are the same. The Victorian two-family on St. Paul Street, the apartment building off Harvard Street, the single-family on Aspinwall Hill with the oversized coal-era flue, each one has its own history, its own undocumented modifications, and its own set of risks. That kind of local knowledge doesn’t come from a call center. It comes from Wendell Pike, the owner, who founded the company in 1999 and still shows up on the roof himself. Ask anyone on your street. Our phone gets answered by a live person around the clock, and the name on the invoice is the same name on the truck.
Brookline homeowners tell us the same story again and again: someone from a national chain quoted one price on the phone, then tried to rewrite it at the door. We don’t work that way. Upfront pricing, in writing, before any work begins. And every job, including Chimney Cap & Crown work, carries the 90-Day Done Right Promise. If it’s not right, one call brings Wendell back at no charge. You’ll also get a real arrival window, a uniformed background-checked technician, and a call if anything slips.
Our Chimney Cap & Crown Services in Brookline
Cap Installation
A proper cap keeps rain, squirrels, starlings, and leaves out of the flue. In Brookline’s attached Victorians and two-families, a missing cap is also the open door that lets exhaust from a shared boiler vent drift back into a decorative fireplace flue. We install stainless steel multi-flue and single-flue caps sized to the actual flue, not guessed from the street. Custom flashings come with it when the crown’s dimensions demand it.
Cap Replacement
An old, rusted, or undersized cap isn’t just unsightly. In a tight Brookline neighborhood like Pill Hill or the Ridges, a shared stack with a failed cap on one flue can affect draft and air quality across multiple units. We’ll match the new cap to the flue’s actual diameter, verify the mesh sizing for animal exclusion, and make sure it seats properly on a crown that can actually hold it.
Crown Repair
Brookline’s older masonry crowns take a beating. Freeze-thaw cycles in January and February, when daytime temperatures creep above freezing and drop back into the 20s at night, force water into hairline cracks and spall the concrete. A cracked crown lets water into the masonry, which accelerates terracotta tile joint failure and can eventually let flue gases migrate between adjacent flues inside a shared stack. We repair crowns before that happens.
Crown Coating
Not every Brookline crown needs to be torn out and rebuilt. When the concrete is still structurally sound but the surface is starting to spall, we’ll coat the crown with a waterproof sealant like Gelco CrownCoat, which bonds to the existing crown and stops water intrusion before the damage spreads. It costs less than a rebuild and buys years of service. The camera footage and a plain-English verdict, every time, no exceptions.

Common Chimney Cap & Crown Problems We See in Brookline Homes
- Shared stacks in attached properties: In Coolidge Corner and Brookline Village apartment buildings, a single stack often serves a gas boiler flue and a decorative fireplace in separate units. When the crown cracks or the cap goes missing, flue gases can migrate between units with no one the wiser until a draft reversal pushes exhaust back into a living space.
- Water-damaged crowns on aging masonry: Most Brookline masonry dates back to 1885-1930. A century of freeze-thaw cycling leaves crowns spalled and porous, which lets moisture into the stack and accelerates terracotta tile joint failure. That moisture path is how creosote-laden smoke eventually finds its way into wall cavities or neighboring units.
- Undocumented B-vents from mid-century gas conversions: When Brookline buildings converted from coal to gas, contractors often ran a smaller B-vent up an existing coal flue and never filed records. In a two-family, that means a neighbor’s boiler exhaust and a tenant’s fireplace share masonry with no proper separation. Any missing cap or cracked crown on one can compromise the other.
- Oversized coal-era flues with no relining: Many Brookline chimneys were built for coal furnaces and ranges. After conversion to gas, those oversized flues were pressed into service without liners, allowing hardened coal-tar deposits to layer beneath decades of creosote. A cap and crown job on these stacks requires understanding what’s underneath, not just what’s on top.

FAQs - Chimney Cap & Crown in Brookline
Yes. In a shared masonry stack, a cracked crown on one side lets water into the middle of the chase and degrades the interior masonry that separates the flues. Once those divisions begin to fail, air pressure from one flue can leak into the other, which weakens the neighbor’s draft and can push smoke back into the room. If you own a two-family in Coolidge Corner or Brookline Village, a crown inspection is the first step whenever either unit reports a draft problem. Call (781) 277-4630 and we’ll put eyes on the actual crown, not a guess from the sidewalk.
A multi-flue cap with a custom chase top, sized to cover all flues on the stack and sealed at the crown, is the standard fix. It keeps rain and animals out of the entire chase while maintaining the draft each flue needs. In a Coolidge Corner building where a gas boiler shares the stack with tenant fireplaces, we also verify that the flue separation is intact before installing the cap. The cap only protects what’s already sound. Call us at (781) 277-4630 for a free assessment.
It can, and this is a real concern in Brookline’s older attached housing. When a decorative fireplace flue shares masonry with a boiler vent and the cap on the fireplace is missing, a draft reversal can pull boiler exhaust through the compromised masonry and into your living space. The fix isn’t just capping the flue. The shared chase needs an inspection to confirm the flues are properly separated. If you suspect this in your building, don’t wait. Call (781) 277-4630 and we’ll inspect the chase and show you the camera footage.
Often, yes. Brookline’s Victorian stacks were built to serve multiple coal-era flues and frequently have non-standard crown shapes that today’s off-the-shelf caps can’t properly cover. A custom stainless cap, fabricated to the actual crown footprint, is the right move when a generic cap would leave gaps or create a draft obstruction. We measure the crown, not the flue, and order the cap to fit. Call (781) 277-4630 and we’ll tell you straight if custom is needed or if a standard cap will do.
If the concrete is still structurally solid but showing surface spalling, hairline cracks, or water staining, a CrownCoat treatment usually stops the damage for a fraction of the cost of a rebuild. If the crown is deeply cracked, crumbling at the edges, or the flue tile itself is damaged, a full rebuild is the honest answer. We’ll show you the camera footage and tell you which one you actually need. If it can wait, we’ll say so. Call (781) 277-4630 and we’ll inspect the crown and give you a flat-price recommendation in writing.
