The short answer

You need a new chimney liner when the existing flue is cracked, deteriorated, or the wrong size for your appliance. This often comes up after a switch from oil to gas. EverSafe inspects the flue with a camera, sweeps it, and installs a properly sized stainless steel liner and cap, following the NFPA 211 standard.

A chimney liner is the channel inside your chimney that carries smoke and exhaust gases up and out of the house. In many older Brooklyn homes, that channel is clay tile or bare brick that has cracked, shifted, or worn away after decades of heat, moisture, and freeze-thaw cycles. When the liner fails, heat and gases can reach the brick and the wood framing around it. EverSafe Chimney Sweep installs new liners for fireplaces, wood stoves, and gas and oil heating appliances in Brooklyn and nearby cities. Every job starts with a camera look at the flue you have now.

Signs you need a new chimney liner

Liner damage is usually hidden inside the chimney, but it leaves clues around the fireplace, the boiler room, and the outside of the chimney. If you notice any of these, have the flue inspected before you use it again.

The last item matters in New York City. When a building converts its boiler from oil to gas, the chimney has to be evaluated as part of the job, and a new liner is often needed. Gas exhaust produces acidic condensate that can corrode a masonry flue, even one that handled oil without trouble.

  • A smoke or creosote smell in the house, especially on humid days or when the fireplace or heater isn't running
  • Poor draft: smoke rolling into the room, fires that are hard to start, or a heating appliance that backdrafts
  • Pieces of clay tile, mortar, or flaking brick collecting in the firebox, the cleanout door, or the base of the flue
  • White, chalky staining on the outside brick, which shows moisture moving through the masonry
  • Water in the firebox or rust on the damper after rain
  • A recent or planned switch from oil to gas, or a new boiler, furnace, water heater, or stove

What's included in a liner installation

Every liner installation follows the same core steps. We adjust them for your chimney and the appliance it serves.

  • Camera inspection of the existing flue to document cracks, gaps, and deterioration
  • Measurement of the flue and review of the appliance's venting requirements so the new liner is sized correctly
  • Sweeping the chimney to remove creosote, soot, and loose debris before the liner goes in
  • Removal of broken tile or obstructions when needed to fit the liner
  • A stainless steel liner sized for your fireplace, stove, or heating appliance, with insulation where clearances call for it
  • Connection to the appliance, or a smoke chamber fitting for a fireplace, at the bottom of the flue
  • A top plate and rain cap to seal the top of the chimney and keep out water and animals
  • A draft check after installation and a final camera pass
  • Photos and a written summary of what we found and what we installed

How our crew works inside your home and on the roof

Inside, the crew lays drop cloths from your door to the fireplace or appliance. We seal the fireplace opening before any sweeping starts. Rotary brushes loosen creosote and soot from the flue walls, and HEPA vacuums run throughout the work to capture fine dust where it's made. We run a camera through the flue before and after the installation, so you can see the condition of the old liner and the finished work.

On the roof, technicians set up safe access, check the crown and flashing, and feed the new liner down from the top. Many Brooklyn rowhouses and attached homes share roof lines and party walls. Before we start, we look at neighboring flues and roof conditions, and we keep the work confined to your chimney. Once the liner is connected at the bottom, we install the top plate and cap and clean up the roof work area.

The standard we follow

Our certified technicians work to NFPA 211, the national standard for chimneys, fireplaces, and vents. It calls for these systems to be inspected once a year, and it guides how we evaluate a flue before and after a liner goes in.

Chimney professionals use three inspection levels. A Level 1 inspection fits when nothing about the system has changed. A Level 2 inspection applies when the system changes, such as a new appliance or a switch from oil to gas, or when the home is being sold. A Level 3 inspection is for cases where a hidden hazard can only be reached by opening part of the chimney or building. Most relining jobs begin at Level 2, because a new liner usually follows a change in appliance or fuel. We use a camera to see the full length of the flue.

What affects the price

We quote each job after seeing the chimney, because no two flues are the same. These are the main factors:

You get a written quote before any work begins.

  • Chimney height and how easily and safely the crew can reach the roof
  • Fuel type and the appliance, which determine the liner material and whether insulation is needed
  • Flue size, shape, and condition, including offsets or bends
  • How much creosote, soot, or debris has to come out first
  • Whether a camera inspection, tile removal, or masonry repair is needed before the liner goes in

How a visit works

First, you contact us and tell us about the appliance, the fuel, and what you've noticed. A technician then inspects the chimney, runs a camera through the flue, and shows you the footage. We explain whether relining is needed and give you a written quote. On installation day, the crew protects your floors, sweeps the flue, installs the liner and cap, and tests the draft. Before we leave, you get photos and a summary of the work.

If a boiler heats your home or building, plan relining before the cold months when you can. New York City's heat season runs from October 1 through May 31. During that period, building owners must keep apartments heated to the city's minimum temperatures. Scheduling the work earlier means less pressure to finish quickly and less time without heat.

What to expect

How a visit goes

  1. Look first, then recommend

    Every visit begins with an inspection of the parts we can reach. Recommendations come from what we actually find, not from a standard package.

  2. Plain explanations

    We tell you what each problem is, why it matters and what happens if it waits. You decide what gets done and when.

  3. A clean work area

    We cover floors and furniture near the fireplace or vent and contain soot and debris while we work. We clean up before we leave.

FAQ

Common questions

How do I know if my chimney needs a new liner?

Common signs include a smoke or creosote smell, poor draft, tile or brick pieces in the firebox, white staining on the outside brick, and water in the firebox. A camera inspection of the flue confirms whether the liner is cracked, missing, or the wrong size.

Do I need a new liner if I switch from oil to gas?

Often, yes. In New York City, the chimney has to be evaluated when a boiler converts from oil to gas. Gas exhaust creates acidic condensate that can corrode a masonry flue, so a new liner sized for the gas appliance is frequently required.

Can I keep using my fireplace if the liner is cracked?

We don't recommend it. A cracked liner can let heat and exhaust gases reach the brick and the wood framing around the chimney. Have it inspected before your next fire.

Will the installation make a mess in my home?

The crew lays drop cloths, seals the fireplace opening, and runs HEPA vacuums while sweeping. Most of the liner work happens from the roof, and we clean up both the inside and roof work areas before leaving.

How long does a liner installation take?

Many installations can be completed in a single visit after the inspection. Chimneys that need tile removal, masonry repair, or work around offsets can take longer. We'll tell you what to expect when we give you the quote.

Do I still need yearly inspections after a new liner is installed?

Yes. The NFPA 211 standard calls for chimneys, fireplaces, and vents to be inspected once a year, whether the liner is old or new.
