STYLE GUIDE

Start with the appliance, then specify the liner

Chimney relining establishes a suitable internal passage for the appliance and fuel being vented. Brown Chimney assesses Boston flues where an existing liner is damaged, its condition is uncertain or a new appliance changes the requirements. A liner needs to work as part of the complete venting system.

Selection considers diameter, height, bends, material suitability, connections and the required insulation. There is no single metal specification that fits every fuel and appliance. The proposed installation follows the liner listing, appliance instructions and applicable requirements for that arrangement.

In an older Boston building, the outer masonry can look intact while the flue inside needs further evaluation. Shared stacks also require clear identification of the flue being used. We establish those details before quoting or assuming the existing passage is ready for new equipment.

The Work

Include the connections and required insulation in the plan

The quote should describe the selected liner system, its size, any necessary removal, insulation, supports and termination. Appliance connectors and access to the base are part of the installation discussion. Required insulation belongs in the scope from the start rather than being presented as an optional climate upgrade.

After installation, the connection and accessible completed work are checked and documented. The handover identifies the appliance served and any ongoing inspection or cleaning needs. Relining does not automatically repair external brickwork, the crown or the roof connection; those conditions are assessed separately.

A chimney inspection can clarify flue condition. Relining may support a new fireplace installation, while damaged outer masonry may need separate repairs.

When should chimney relining be assessed?

A change in equipment or a documented flue defect is a reason to evaluate the venting system. Symptoms alone do not establish which liner or repair is appropriate.

01

An inspection identifies cracked, missing or deteriorated liner material.

02

A new appliance has different sizing or venting requirements.

03

The existing flue's construction and condition are unknown.

04

The current liner is unsuitable for the appliance or fuel it serves.

How a Boston chimney liner project is scoped

We assess the flue and appliance, select an appropriate system and define access and removal needs. Installation includes the specified connections and required insulation, followed by documentation of the completed work.

01

Assessing the existing flue

The flue is assessed before anything is quoted. Where the interior needs to be seen rather than assumed, a camera inspection is offered as its own line — you'll know the cost before we run it.

02

Liner system selection for Boston homes

The liner is selected and sized for the appliance, fuel, chimney dimensions and venting requirements. The proposed system identifies an appropriate listed liner, connectors and any required insulation. Material suitability follows the appliance and liner instructions and applicable requirements, rather than a single metal specification for every installation.

03

Old liner removal

Where a failed liner is already in place, it comes out first — top plate, cap, and full extraction — and the bare flue is re-inspected before anything new goes down.

04

Liner installation and insulation in Boston

The selected liner is installed with the required insulation, supports, termination and appliance connection. The installation follows the liner listing, appliance instructions and applicable requirements. Insulation required for the selected system is included in the installation scope; it is not treated as an optional cold-weather upgrade.

05

Connection & walkthrough

The appliance connection is completed and the finished installation walked through with you, with the 1-year workmanship warranty on all labor performed.

What liner does your flue actually need?

The liner material follows what you burn: stainless steel for wood, aluminum for gas appliances only. Tell us the appliance, what the flue looks like inside and how tall the chimney is, and see what happens to combustion gases in a failed flue, which liner fits, and the price lines from our price book.

Stainless steel liner

Stainless steel, full flue height

A wood-burning system needs a stainless steel liner rated for wood. It runs the full height of the flue with a top plate, liner cap and the connection to your fireplace, which keeps heat and combustion byproducts off the masonry and the framing around it.

  • Level 2 inspection with cameraIf the flue has not been documented with a camera yet. Credited toward repair work booked within 30 days.$350
  • Stainless steel liner, 25 ft$1,750 plus $125 per foot of chimney height, minimum $3,500. Offsets, extra connections or an unusual chimney are priced on site; hard access adds $500.$4,875

  • Building permit, where the town requires oneApplication, filing and the town inspection.$1,200

There may be an alternative: HeatShield

Where the clay tiles are cracked but sound enough to coat, a ceramic flue coating can restore the flue instead of relining it: $1,500 plus $125 per foot of flue height, minimum $3,500. At 25 ft that is $4,625. The technician confirms on site whether your flue can be coated or needs a new liner.

A clear plan for your Boston chimney project.

Roof access planned early
Tell us about roof hatches, narrow side passages, and access restrictions when you get in touch. We factor the building's layout into the proposed work and quote.
Shared-building details clarified
For a condo or multi-unit property, let us know who manages the building and which areas are shared. Access arrangements and any association approvals should be clarified before work begins.
Historic status considered
Exterior changes to a designated Boston landmark or a property in a local historic district may need preservation approval. Check the property's status and applicable requirements before scheduling exterior chimney alterations.
Scope and price set out in writing
Your quote identifies the proposed work and its price before you approve it. That gives you a clear basis for deciding what to schedule and discussing any changes to the scope.

For transparency

What this visit doesn't cover.

Camera evaluation, old-liner removal and difficult access must be identified where needed.

The quote should include insulation required by the selected listed system and installation conditions.

Masonry, crown, flashing and appliance replacement are separate scopes unless listed with the liner work.

Boston chimney liner and relining FAQs

1 icon

What decides the cost of chimney relining in Boston?

Each liner is quoted individually after the appliance and flue are assessed. Diameter, height, material, insulation, connections and access are what move the price, and the options are set out on our chimney liner pricing page.
Faq Number

How do you choose the right chimney liner?

The choice follows the appliance, fuel and venting requirements, along with the chimney's dimensions and condition. The liner listing and manufacturer instructions govern suitable applications. A material appropriate for one system may be unsuitable for another.
3 icon

Is liner insulation optional?

Not when the selected system, listing or installation conditions require it. The assessment determines the insulation requirements for the proposed installation. Required insulation should be included in the scope and price rather than treated as an optional cold-weather addition.
4 icon

Does an older Boston chimney automatically need relining?

No. Age alone is not enough to make that decision. The condition of the existing flue and its compatibility with the appliance matter. An appropriate inspection can identify damage or a mismatch that supports a relining recommendation.
5 icon

Can a new liner fix a chimney leak?

Relining addresses the internal venting path; it is not a general cure for rain entering through masonry, a crown or flashing. If moisture symptoms are present, the source should be assessed and any separate exterior repairs identified.
