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.

Why Boston Homes Are Different
Boston’s housing stock is among the oldest in the nation. Federal and Victorian brick row houses on Beacon Hill, in Back Bay, and the South End sit alongside wood-frame triple-deckers concentrated across Dorchester, Jamaica Plain, Roxbury, and South Boston. Those triple-deckers typically share a single masonry chimney with multiple stacked flues serving all three units, and landlords often address only the flue tied to the complaining tenant. Adjacent flues accumulate years of creosote, creating cross-unit carbon monoxide risk that’s structurally baked into this housing type.
Original chimneys were sized and lined for coal stoves, then repurposed for oil burners or gas appliances without proper relining. Flues are oversized for modern appliances, prone to excessive condensation, and often lack any UL-listed liner. Boston’s coastal climate subjects masonry to severe freeze-thaw cycles, with temperatures crossing 32°F dozens of times each winter. Salt-laden air off Boston Harbor accelerates mortar spalling in East Boston, Charlestown, and South Boston.
In brownstone-to-condo conversions across Beacon Hill and the South End, chimney ownership frequently sits ambiguous across multiple unit owners. Technicians find shared chimneys where three or four separate owners share one structure, none having authorized a full multi-flue cleaning in a decade.

Before
AfterChimney Cap & Crown in Boston
Boston’s triple-decker chimneys and single-wythe brick construction make cap and crown failures especially costly. A compromised crown on a shared chimney in Dorchester or Jamaica Plain lets water into multiple flues simultaneously, accelerating liner deterioration across units. We install and repair caps and crowns with materials sized for Boston’s older, often-oversized flue openings, and every job starts with a written price under Haven Standard Clause 1. Chimney Cap & Crown
Crown Repair
Signs you need it
Visible cracks in the concrete crown, water staining on interior chimney faces, or pieces of crown material in the firebox.
What it costs in Boston
Crown repair in Boston typically runs $850-$1,800 depending on accessibility and whether the chimney serves one unit or three.
How we do it
We grind out cracked concrete, apply a bonding agent, and pour new crown material with a minimum 2-inch overhang and drip edge, then document the repair with photos.
Multi-Flue Cap
Signs you need it
Missing or rusted caps on shared triple-decker chimneys, debris or animal entry in any flue, or water damage visible in multiple units.
What it costs in Boston
Multi-flue cap installation in Boston ranges $1,200-$2,400 for stainless steel covers sized to protect all flues on a shared chimney.
How we do it
We measure all flue openings, fabricate or order a custom cap with screened sides, and anchor it to the crown with stainless steel fasteners rated for coastal exposure.
What Chimney Cap & Crown Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Crown repair | $850-$1,800 |
| Crown coating | $600-$1,200 |
| Multi-flue cap installation | $1,200-$2,400 |
| Full crown rebuild | $2,000-$4,500 |
How long does a crown repair last in Boston?
A properly poured concrete crown with correct overhang lasts 15-25 years even with Boston’s freeze-thaw cycles; coating alone lasts 5-8 years and requires reapplication. We warranty crown repairs for 365 days under our Done Right Promise.
Can you install a multi-flue cap on a triple-decker chimney?
Yes, we fabricate custom multi-flue caps for Boston’s shared chimneys and coordinate installation with all affected unit owners when access requires it. Call (781) 649-9326 for exact measurements and pricing.
Chimney Liner & Rebuild in Boston
Boston’s coal-era chimneys were never designed for modern gas and oil appliances, leaving flues that are too large, too cold, and too porous for efficient, safe venting. Condensation inside these oversized flues produces acidic runoff that deteriorates mortar from the inside out, especially in triple-deckers where one flue may be active while others sit cold. We install UL-listed stainless steel and flexible liners sized to the appliance, with camera verification of the full installation. Chimney Liner & Rebuild
Stainless Steel Liner
Signs you need it
Flaking terracotta liner pieces in the firebox, visible gaps in the flue wall on camera inspection, or a gas appliance venting into an unlined masonry flue.
What it costs in Boston
Stainless steel liner installation in Boston runs $2,800-$5,500 depending on flue height, diameter, and whether the chimney serves one unit or multiple.
How we do it
We drop a camera to assess the full flue, measure for a rigid or corrugated stainless liner from DuraFlex or Olympia Chimney, and install it with proper top and bottom termination, then photograph every joint.
Partial Rebuild
Signs you need it
Spalling brick above the roofline, a leaning chimney stack, or mortar loss severe enough that the liner cannot be safely installed without structural repair.
What it costs in Boston
Partial rebuilds from the roofline up in Boston typically cost $4,500-$8,000, with taller triple-decker stacks at the higher end.
How we do it
We dismantle the damaged courses, salvage reusable brick where possible, pour a new concrete crown, and rebuild to original dimensions with matching mortar composition.
What Chimney Liner & Rebuild Costs in Boston
| Item | Typical range in Boston |
|---|---|
| Stainless steel liner | $2,800-$5,500 |
| Flexible liner | $2,200-$4,800 |
| Partial rebuild | $4,500-$8,000 |
| Full chimney rebuild | $8,000-$15,000 |
Does every old Boston chimney need a new liner?
Not necessarily; we camera-inspect first and only recommend relining when the flue is unlined, damaged, or improperly sized for the connected appliance. Our Free Second Opinion applies to any competitor’s relining quote.
How disruptive is a liner installation in a occupied triple-decker?
Most installations take one day with minimal interior disruption; we coordinate access with all unit owners when flues are shared and protect floors and furnishings throughout. Call (781) 649-9326 to schedule around tenant availability.

FAQs About Chimney Cleaning in Boston
Most chimney repairs and liner installations require a Boston building permit; we pull permits as part of our standard process and include the documentation in your job record. Permit fees are listed separately on your written estimate.
We inspect and document all flues in a shared chimney, then provide separate written quotes per unit so each owner can authorize work independently; we also offer group scheduling discounts when multiple units commit to simultaneous service.
We typically schedule inspections within one week and most cap, crown, or liner work within two weeks of estimate approval; emergency situations involving active leaks or blocked flues receive priority scheduling. Call (781) 649-9326 for current availability.
