The short answer

You likely need a chimney liner if your flue tiles are cracked or missing, you see brick flakes or white staining, or you're converting a boiler from oil to gas. EverFlame Chimney Care inspects the flue with a camera, sizes a liner to your appliance, and installs it with a clean, protected work area inside and safe access on the roof.

A chimney liner is the protective channel inside your flue that carries smoke and exhaust gases up and out of the house. It keeps heat, moisture, and acidic combustion byproducts away from the brick and mortar, and away from the wood framing that sits close to many chimneys. In older New York homes, the original clay tiles are often cracked or shifted, and some chimneys were built with no liner at all. A liner also matters when you change fuel or install a new furnace, boiler, or water heater, because the flue has to match what is venting through it. EverFlame Chimney Care installs liners for homeowners in New York City and nearby cities. This page covers the signs that point to a liner problem, what the job includes, how our crew works in your home and on your roof, the standard we follow, what affects the price, and how a visit works.

Signs you need it

Liner problems are usually hidden inside the chimney, but they tend to show up as changes you can see, smell, or feel around the fireplace or appliance. If you notice any of the following, have the flue inspected before the next heating season.

  • A smoke or creosote smell in the room, especially on humid days or when the fireplace isn't in use
  • Poor draft: smoke rolling into the room, fires that are hard to start, or an appliance that struggles to vent
  • Debris, brick flakes, or pieces of clay tile collecting in the firebox or at the base of the flue
  • White staining on the brick, inside or outside, which can mean moisture is 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 furnace, boiler, or water heater connected to the chimney

What's included in a liner installation

Every installation starts with finding out what's actually inside your chimney. From there, we size and fit a liner to the appliance or fireplace it will serve. Here is what the job covers:

  • Camera inspection of the full flue to document cracks, gaps, missing tiles, and blockages
  • Measurement of flue height and interior dimensions, and review of the appliance's venting needs
  • Cleaning of the existing flue to remove creosote, soot, and loose debris before the liner goes in
  • Removal of broken tile or obstructions where needed so the liner can pass through
  • Installation of a liner sized for your fuel type and appliance, with the required connections at the bottom
  • Insulation around the liner where the chimney and appliance call for it
  • A top plate and chimney cap to seal the top of the flue and keep out rain and animals
  • A final draft check and camera review of the completed installation, with photos you can keep

How our crew works in your home and on your roof

Inside, we lay drop cloths from the door to the fireplace or appliance and cover nearby furniture and flooring. We seal the fireplace opening or appliance connection while we work, and we run HEPA vacuums throughout the job to capture soot and dust at the source. Rotary brushes clean the old flue walls so the camera gives a clear picture and the new liner has a clean path.

On the roof, our certified technicians set up safe access before anything else, using ladders and fall protection suited to your roof's height and pitch. The liner is fed down from the top, connected at the base, and sealed at the crown with a top plate and cap. For row houses and attached homes, we plan roof access ahead of time so we don't disturb neighboring property. Before we leave, we remove all debris, vacuum the work area, and walk you through what we did.

The standard we follow

Our work follows NFPA 211, the national standard for chimneys, fireplaces, and vents. It calls for chimneys to be inspected once a year. Chimney professionals use three inspection levels: Level 1 when nothing about the system has changed, Level 2 when the system changes (such as a new appliance or a switch of fuel) or the home is sold, and Level 3 when a hidden hazard can only be reached by opening part of the chimney or building. A liner installation usually involves at least a Level 2 inspection, because it comes with a change to the venting system.

If you're converting a boiler from oil to gas in New York City, the chimney has to be evaluated as part of the work. A new liner is often needed because gas exhaust produces acidic condensate that can corrode a masonry flue. Since the city's heat season runs from October 1 through May 31, we recommend scheduling inspections and liner work in late spring or summer so your heat isn't interrupted when you need it.

What affects the price

We give you a written quote after the inspection, because every chimney is different. The main factors are:

  • Chimney height and how hard it is to access the roof safely
  • The fuel and appliance being vented: wood, gas, or oil, and whether it's a fireplace, furnace, boiler, or water heater
  • Flue size and condition, including offsets, bends, or damaged tile that has to be removed
  • How much creosote or buildup needs to be cleaned out first
  • Whether a camera inspection, insulation, or masonry or crown repair is needed along with the liner

How a visit works

First, we schedule a time and ask about your appliance, fuel type, and any symptoms you've noticed. At the visit, we protect the work area, inspect the chimney from the firebox and the roof, and run a camera through the flue. We show you the footage, explain what we found, and give you a written quote with the options that fit your chimney.

If you approve the work, we either install the liner the same day or book a return visit once the right materials are ready. On installation day, we clean the flue, fit and connect the liner, seal the top, test the draft, and clean up completely. You get photos of the finished work and a plain explanation of what to watch for between yearly inspections.

What to expect

How a visit goes

  1. Look first, then recommend

    We inspect the chimney, vent or duct before suggesting any work, and we explain what we see in plain terms so you can decide what to do.

  2. Show you what we found

    We take photos of the flue, firebox, crown, vent run or ductwork so you can see the condition for yourself instead of taking our word for it.

  3. Respect your home

    We cover floors and furniture, contain soot and dust with sealed equipment, and leave the work area clean when we finish.

FAQ

Common questions

How do I know if my chimney even has a liner?

You often can't tell from the fireplace. A camera inspection shows whether the flue has clay tile, metal, or bare brick, and whether the existing lining is intact.

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

Often, yes. In New York City, the chimney has to be evaluated during an oil-to-gas boiler conversion. Gas exhaust produces acidic condensate that can corrode a masonry flue, so a properly sized liner is commonly required.

How long does a liner installation take?

Most installations take a single day once materials are on hand. Tall chimneys, difficult roof access, or added masonry repair can extend the work.

Will installing a liner make a mess in my house?

We lay drop cloths, seal the fireplace or appliance opening, and run HEPA vacuums throughout the job. When we're done, we clean the work area before we leave.

Can I keep using my fireplace or heater before the liner goes in?

If the inspection finds cracked or missing tile, we'll tell you whether it's safe to keep using the appliance in the meantime. In many cases, we'll recommend holding off until the flue is repaired.

Do I still need yearly inspections after a new liner?

Yes. NFPA 211 calls for chimneys, fireplaces, and vents to be inspected once a year, even with a new liner in place.
