The short answer

You likely need a new chimney liner if your flue tiles are cracked or flaking, your fireplace drafts poorly, or you are converting a boiler from oil to gas. CrestFlue inspects the flue with a camera, then installs a liner sized to your appliance, working cleanly inside the home and safely 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. When the original clay tiles crack, crumble, or no longer match the appliance they serve, heat and corrosive gases can reach the brick and the wood framing around it. CrestFlue Chimney Service installs new liners for homeowners in Staten Island and nearby communities in Brooklyn and New Jersey. We start by looking inside the flue. We explain what we find in plain terms and size the liner to the fireplace, stove, furnace, or boiler it serves. Many Staten Island homes have older masonry chimneys, and many have switched heating fuels over the years, so liner problems are common here. This page covers the warning signs, what the job includes, how our crew works, and what affects the cost.

Signs you need it

Liner damage usually happens out of sight, but it tends to leave clues. If you notice any of the signs below, schedule an inspection before the next heating season. In New York City, heat season runs from October 1 through May 31, and your boiler or furnace depends on a sound flue for all of those months.

  • A smoke or creosote smell in the house, especially on humid days or when the appliance is off
  • Poor draft: smoke rolling into the room, fires that are hard to start, or a furnace or boiler that backdrafts
  • Debris or brick flakes in the firebox, including pieces of broken clay flue tile
  • White staining on the outside brick, a sign that moisture is moving through the masonry
  • Water in the firebox or at the base of the chimney after rain
  • A planned or recent switch from oil to gas, or a new appliance connected to an old flue

What's included in a liner installation

Every liner job is built around the appliance it serves and the condition of the chimney. In most cases the new liner is stainless steel, sized to match the venting needs of your fireplace insert, stove, furnace, or boiler. If you are converting from oil to gas, the chimney has to be evaluated as part of the work. A new liner is often needed in that case because gas exhaust produces acidic condensate that can corrode a masonry flue. Here is what a typical installation covers.

  • Camera inspection of the existing flue to document cracks, gaps, and deterioration
  • Cleaning the flue to remove creosote, soot, and loose tile before the liner goes in
  • Sizing the liner to the appliance and flue dimensions
  • Removing broken tile or obstructions where needed so the liner can pass through
  • Installing the liner from top to bottom, with insulation where the application calls for it
  • Connecting the liner to the appliance with the proper fittings
  • Sealing the top with a top plate and installing a chimney cap to keep out rain and animals
  • A final check of draft, plus photos so you can see the finished work

How our crew works in your home and on the roof

Inside, our certified technicians lay drop cloths from the door to the fireplace or appliance before they set down any tools. A HEPA vacuum runs during cleaning so soot and fine dust are captured rather than spread through the room. Rotary brushes clear creosote and loose debris from the flue walls, and we run a camera through the flue before and after the work so you can see what changed.

On the roof, the crew sets up safe access before handling any materials. The liner is fed down the flue from the top while a technician below guides it and makes the connection to the appliance. Then we seal the top, fit the cap, and check the crown and flashing for problems you should know about. When we leave, we take our debris with us and walk you through the photos.

The standard we follow

Our liner work follows the NFPA 211 standard. It calls for chimneys, fireplaces, and vents to be inspected once a year. Chimney professionals use three inspection levels. Level 1 applies when nothing about the system has changed. Level 2 applies when the system changes, such as a new appliance or a switch in fuel, or when the home is sold. Level 3 applies when a hidden hazard can only be reached by opening part of the chimney or the building.

Installing a new liner, connecting a new appliance, or converting from oil to gas is a change to the system. That means a Level 2 inspection, including a camera look inside the flue, is the normal starting point for liner work.

What affects the price

Every chimney is different, so we quote after we have seen yours. These are the main factors.

  • Chimney height and roof access, including roof pitch and how hard the chimney is to reach
  • Fuel type and the appliance being vented: wood, gas, or oil
  • Flue size and condition, and whether broken tile has to be removed first
  • How much creosote or soot buildup has to be cleaned before installation
  • Whether a camera inspection, insulation, or repairs to the crown, cap, or masonry are needed

How a visit works

First, you contact us and describe what you have noticed, such as a smell, poor draft, staining, or an upcoming fuel conversion. We schedule an inspection visit, and the technician looks at the appliance, the firebox, and the roof, then runs a camera through the flue.

Next, we show you the footage and explain whether a liner is needed and why. If it is, you get a written quote that lists the scope of work. On installation day the crew protects your floors, cleans the flue, installs and connects the liner, caps the chimney, and checks the draft. Before we leave, we review the photos with you and remind you that the chimney should be inspected once a year from then on.

What to expect

How a visit goes

  1. Inspect first, then recommend

    We don't recommend repairs until we've looked at the system. You'll hear what we found, why it matters, and which items are urgent and which can be planned for later.

  2. Clear explanations

    We describe problems in plain terms and show you photos, so you can see the cracked crown or the blocked vent for yourself instead of taking our word for it.

  3. Respect for your home

    We use drop cloths and containment where they're needed, keep soot and debris out of your living space, and leave the work area clean.

FAQ

Common questions

Don’t see your question? Call (681) 344-0701 and we’ll talk it through.

How do I know if my chimney liner is damaged?

Common signs include pieces of clay tile in the firebox, poor draft, a smoky or creosote smell, white staining on the brick, and water in the firebox. A camera inspection of the flue is the only reliable way to confirm the damage.

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

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

Will the installation make a mess in my house?

We lay drop cloths, use HEPA vacuums while cleaning, and do most of the liner work from the roof. When we finish, we remove our debris and leave the work area clean.

What kind of liner do you install?

Most installations use a stainless steel liner sized to the appliance it serves, with insulation where the application calls for it. We recommend a specific option after we inspect the flue.

How often should my chimney be inspected after a new liner goes in?

The NFPA 211 standard calls for chimneys, fireplaces, and vents to be inspected once a year. A new liner doesn't change that.

Do you work outside Staten Island?

Yes. We serve Staten Island homeowners and nearby communities in Brooklyn and New Jersey. Contact us to confirm that your address is in our service area.
