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.

AfterChimney Cleaning in Boston, MA
Chimney cap and crown work in Boston is different because so many of the city’s 1870s-1920s triple-deckers and brownstones run multiple flues through a single shared masonry stack. A cracked crown or missing cap on one of those stacks sends water into every flue below it, not just one. We quote cap, crown, and liner work in writing before anything starts, and we document it with camera photos when it’s done. Call (857) 567-8887 for a free estimate.
Why Boston Homes Are Different
Boston’s housing stock is among the oldest in the country. The triple-decker stacks that dominate Dorchester, South Boston, Roxbury, and Jamaica Plain were mostly built between the 1880s and 1920s. Most of them have shared flues serving wood-burning fireplaces on every floor, and many were built without modern clay-tile liners. In the Back Bay and South End, brownstones sit on filled tidal land, so decades of differential settlement have left chimney stacks leaning or cracked at the roofline. Routine cleaning and structural inspection are inseparable in those neighborhoods.
The weather works against Boston chimneys all year. About 43 inches of snow each winter, constant freeze-thaw cycling, and Atlantic salt air in East Boston, South Boston, and Charlestown spall brick faces and erode the soft lime-mortar joints common in 19th-century masonry. A chimney that would be fine 30 miles inland can need crown and cap work here years sooner. Corrine Halstead, who leads our Boston operation, reviews the camera footage from every inspection personally before we recommend anything.
Our Main Boston Services
The two services Boston homeowners call us about most are cleaning and repair, but fireplace work rounds out what we handle across the city. Here’s what each involves in Boston specifically:
Chimney Cleaning & Sweep in Boston
Cleaning a Boston chimney often means working on a stack that hasn’t been touched in years because no one in a three-unit building was sure whose job it was. We remove creosote at every level, run a camera through the full flue length, and give you photos of what we found along with a written price for any follow-up work. Chimney Cleaning & Sweep in Boston covers the full process.
Chimney Repair in Boston
Repair in Boston usually starts with what the camera shows inside a century-old flue: cracked clay tiles, spalled brick from decades of freeze-thaw, or a smoke chamber that was parged improperly generations ago. We write up the scope and price before any work begins, and every job ends with a documented photo record. Chimney Repair in Boston has the details.
Fireplace Services in Boston
Fireplace work in Boston ranges from repointing a Victorian firebox in the South End to rebuilding a damper in a Dorchester triple-decker that hasn’t closed properly since the 1990s. We inspect the firebox, damper, and smoke chamber with the same camera standard we use on every flue. Fireplace Services in Boston walks through what that includes.

BeforeAfterChimney Cap & Crown in Boston
In Boston, cap and crown failures are the leading source of water damage to old masonry chimneys. A cracked crown on a triple-decker stack lets rain and snowmelt into every flue below it, accelerating creosote formation and eroding mortar from the inside out. On brownstones in the Back Bay and South End, frost heave and settlement cracks make crown inspection essential every time we’re on the roof. Our Chimney Cap & Crown work addresses the full system, from the flue tile up.
Cap Installation
Signs you need it
Water streaks on the flue tile, animals nesting in the chimney, or downdrafts that push smoke back into the room all point to a missing or undersized cap.
What it costs in Boston
A stainless or copper cap installed on a Boston chimney typically runs $250-$600 depending on flue size and roof access.
How we do it
We measure the flue opening, secure the cap to the flue tile or crown with mechanical fasteners, and photograph the finished install.
Crown Repair
Signs you need it
Cracks wider than a quarter inch, spalling at the crown edge, or standing water on top of the chimney after rain mean the crown is failing.
What it costs in Boston
Recasting a damaged crown in Boston generally costs $650-$1,500, with multi-flue stacks at the higher end.
How we do it
We remove the deteriorated crown, form a new one with a proper overhang and drip edge, and seal it with a flexible crown coat.
What Chimney Cap & Crown Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Cap installation | $250 - $600 |
| Crown repair | $650 - $1,500 |
| Multi-flue cap | $450 - $900 |
Does a cracked crown really need to be fixed right away?
Yes. Water that gets through a crack in Boston winters freezes and thaws repeatedly, widening the crack each cycle. Within two or three winters, what started as a $700 repair becomes a $4,000 crown and top-course rebuild. Call (857) 567-8887 for a written quote when you first see cracking.
Do I need a new cap if I only use my fireplace occasionally?
Yes, because the cap’s job is protecting the flue from water and animals year-round, not just during burning season. A missing cap on an unused flue still lets rain into the masonry. We include cap condition in every Boston inspection.
Chimney Liner & Rebuild in Boston
Boston’s oldest chimneys were built for coal, converted to oil, and now vent high-efficiency gas appliances through flues that are badly oversized. That mismatch causes condensation, which dissolves old mortar and accelerates creosote buildup. On triple-deckers with shared stacks, an unlined flue is a liability issue for landlords across every unit at once. Our Chimney Liner & Rebuild work starts with a camera down the full flue so you can see exactly what we see.
Stainless Steel Liner
Signs you need it
Clay tiles cracked or missing from the camera footage, or a fuel conversion from oil to gas that left the flue oversized and prone to condensation.
What it costs in Boston
A stainless liner in a Boston chimney typically runs $3,500-$6,500 depending on flue height and roof access.
How we do it
We size the liner to the appliance and flue dimensions, drop it from the top of the stack, and insulate the annulus before reconnecting the appliance.
Partial Rebuild
Signs you need it
Loose or missing bricks above the roofline, a leaning stack visible from the ground, or mortar joints that crumble when probed.
What it costs in Boston
Rebuilding the top 15-25 courses of a Boston chimney costs $2,800-$5,000 on average.
How we do it
We tear down to sound masonry, rebuild with new brick and historically appropriate mortar, and install a new crown and cap.
What Chimney Liner & Rebuild Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Stainless steel liner | $3,500 - $6,500 |
| Partial rebuild | $2,800 - $5,000 |
| Full rebuild | $8,000 - $18,000 |
How do I know if I actually need a new liner?
The camera footage tells you. If the clay tiles are cracked, missing, or glazed with heavy creosote, the liner has failed and needs replacement. We show you the video before we quote anything, and nothing gets recommended without that evidence.
Can a full rebuild be delayed if the chimney isn’t used?
Sometimes. If the flue is capped, the stack is stable, and there’s no active water intrusion, a rebuild can often wait a season or two. Call (857) 567-8887 and we’ll tell you plainly, with photos to back it up.

We install and service liners and caps from Gelco, Famco, and Copperfield, all sourced through Haven’s buying network to keep customer pricing honest. Parts are stocked at our Boston office, which means most cap and crown jobs don’t wait on shipping. See our brands for the full list.

Roof access drives price more than anything else in Boston.

FAQs About Chimney Cleaning in Boston
Most Boston addresses can be scheduled within one to two business days. Triple-decker and brownstone roofs take a little longer to schedule because we send a two-person crew for safety on steep pitches. The written quote is delivered before any work starts, no matter the timing.
Most cleaning, cap, and crown work in Boston doesn’t require a permit. Rebuilds that alter the structure above the roofline may, depending on scope and whether the building is in a historic district. We tell you if a permit applies and handle it as part of the written scope.
We inspect the full stack as one system, not floor by floor. You get one written report covering every flue, with camera photos showing what each tenant’s fireplace is venting through. That documentation is what insurers and tenants both respond to. Call (857) 567-8887 and ask for a multi-flue inspection.

What Boston Customers Say

- Gregory F."We were buying the house and needed a real inspection. The report had photographs, the standard it was done to, and a clear repair figure. The seller paid for the repair."
- Lorna D."They told me the flue was fine and I did not need a liner. Charged me for the inspection and nothing else. That is why I have called them twice since."
