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.
Fast, Reliable Chimney Liner & Rebuild Across Somerville
Chimney liner replacement and partial rebuilds in Somerville typically run $1,800-$4,500 depending on flue count and stack height, with most jobs completed in a single visit after a Level-2 camera inspection. Our crews serve Somerville from our Boston office, and we’ve worked on triple-decker chimney stacks from Winter Hill to Spring Hill to Davis Square for over 42 years. Call (857) 754-5607 to speak with a live person and book a free estimate.
Somerville’s triple-decker housing stock presents chimney problems you won’t find in newer suburbs. Each stack often contains two or three flues serving separate units, and it’s common to find one flue abandoned during a heating conversion while its neighbor stays active. That dead flue pulls cold air and moisture through bare brick, silently undermining the draft and safety of the live flue inches away. Our Chimney Liner & Rebuild team maps every flue before recommending work.

The number on the estimate is the number on the invoice.
Dispatch and scheduling are coordinated from our Boston office, but crews serve Somerville locally.

That local knowledge means we arrive knowing what to look for.
Our Chimney Liner & Rebuild Services in Somerville
Stainless Steel Liner Installation
A stainless steel liner is the right fix for most active flues in Somerville’s pre-war triple-deckers. The original clay liners in these coal-era stacks were sized for different fuel and different appliances. When a unit converted to gas or oil without re-lining, the flue became oversized, causing poor draft and creosote condensation on bare brick. We install DuraFlex or Olympia Chimney stainless steel liners sized precisely to the appliance, with proper insulation to meet Massachusetts code. In a triple-decker, we isolate the live flue and document which unit it serves.

Flexible Liner Installation
Some Somerville chimney stacks have offsets or bends that make rigid stainless steel impossible to feed. A flexible liner navigates those turns while still providing a sealed, properly sized flue path. We see this often in the older triple-deckers near Prospect Hill, where the original builders used whatever brick configuration fit the narrow lot. Flexible liners from DuraFlex handle the geometry without sacrificing draft performance or safety.

Liner Replacement
Replacement becomes necessary when the existing clay tile liner is cracked, spalled, or missing sections - common in Somerville after decades of freeze-thaw cycling. Our camera inspection shows you exactly where the damage is. We don’t guess. If the clay is sound in sections, we’ll say so. If it’s failing, we explain why and show you the photo. Liner replacement in Somerville triple-deckers often involves working around adjacent flues that may be active, abandoned, or capped, so mapping the stack correctly is the critical first step.

Partial Rebuild
Somerville’s harsh freeze-thaw cycles destroy mortar joints on the exposed upper sections of tall triple-decker stacks. Spalling brick, failed crowns, and deteriorated top courses are near-universal findings on pre-war buildings here. A partial rebuild addresses the damaged upper masonry without tearing down the entire stack. We rebuild with matching brick where possible, install a proper concrete crown with drip edge, and flash the chimney to the roof correctly. Spring is peak season for these jobs because each winter inflicts measurable new damage.

Common Chimney Liner & Rebuild Problems We See in Somerville Homes
- Assuming all flues in a shared stack are active. In a Somerville triple-decker, one unit may have converted to forced hot water and capped its flue while another still burns fuel. A liner sized for the wrong flue, or a dead flue left open to channel moisture, creates draft problems and masonry damage that spread to the active flue beside it.
- Skipping the camera inspection. An oversized coal-era flue can hide cracked clay tile or third-degree creosote glaze behind what looks like a clean surface. A brush-and-vacuum cleaning without camera verification leaves the fire hazard untouched. We document what we find with photos you can see.
- Rebuilding only the visible crown without addressing the stack. The tall, exposed masonry on Somerville triple-deckers suffers joint failure far below the crown. Rebuild the top courses and crown but ignore failed mortar on the stack itself, and the next freeze-thaw cycle reopens the same leak path. We inspect the full height.
- Installing a liner without insulating or properly sealing. Massachusetts code requires proper clearances and insulation for liner installations. An uninsulated liner in a cold, exterior chimney runs too cool, causing creosote condensation and poor draft. We do it to code, not to minimum.

FAQs - Chimney Liner & Rebuild in Somerville
We map every flue with a Level-2 camera inspection before recommending any work. Our technician feeds a camera down each flue, documents what appliance (if any) it connects to, and notes whether it’s active, capped, or abandoned open. In Somerville triple-deckers, it’s common to find one flue serving a gas boiler, another capped when a unit converted to forced hot water, and a third abandoned open to the weather. You get a photo report showing which flue serves which unit, so there’s no guesswork. Call (857) 754-5607 to schedule - estimates are free.
If you use a wood-burning fireplace infrequently, an annual sweep may be more than necessary; the NFPA recommends annual inspection, with cleaning based on what the inspection finds. In Somerville, many triple-decker chimneys serve gas or oil appliances, not fireplaces, and those flues still need inspection for liner integrity, draft performance, and carbon monoxide safety. Bare brick or cracked clay tile in an active flue is a hazard regardless of how often you light a fire. We’ll tell you honestly whether your flue needs cleaning, repair, or simply monitoring. Call (857) 754-5607 for a free estimate.
A properly installed stainless steel liner can last 15 to 20 years or more, while original clay tile liners in Somerville’s 1885-1920 triple-deckers often fail after 80 to 100 years of freeze-thaw cycling. The real question is condition, not age. Our camera inspection shows cracked tile, spalled sections, or missing liners that require replacement now. We don’t replace liners that are sound, and we don’t leave failing ones in service. You’ll see the photos and get a straight answer. Call (857) 754-5607.
The camera inspection shows the interior condition of every flue in your stack: cracked or missing clay tile, creosote buildup grade, obstructions, moisture damage, and the connection point to your appliance. The photo report documents each finding with a plain-English verdict, not technical jargon. In Somerville triple-deckers, it also maps which flue serves which unit, critical when multiple tenants share one stack. You see what we see. Nothing is recommended without evidence you can verify yourself. Call (857) 754-5607 to book - estimates are free.
Most liner installations and partial rebuilds are completed in a single visit because we stock the materials and confirm the scope during the initial camera inspection. The price we agree to before booking is the price on the invoice - no surprises. If we encounter truly hidden damage that the camera could not reveal, we stop, show you the photo, and discuss options before proceeding. We don’t proceed with extra work without your okay. That’s the square deal. Call (857) 754-5607 for a free estimate.
