The short answer

If your South Williamsburg chimney has a cracked, deteriorated or missing liner, or your building is switching its boiler from oil to gas, you will likely need a new liner. EverSafe Chimney Sweep inspects the flue first, then sizes and installs a liner matched to the appliance it serves.

A chimney liner is the protective channel that carries smoke and exhaust gases up and out of your home. In South Williamsburg, many homes and buildings still rely on old masonry flues that were built for coal or oil, not for today's gas boilers and water heaters. EverSafe Chimney Sweep installs new liners for homeowners and building owners in the 11249 ZIP code. Our office in Fort Greene is about 2 miles southwest, so our certified technicians can reach you to inspect your flue, explain what we find, and reline the chimney when it needs it.

Why South Williamsburg Chimneys Often Need Relining

The neighborhood's housing mix includes rowhouses, brownstones, pre-war apartment buildings and some newer construction. In older masonry buildings, the original flue is often clay tile or bare brick. Over decades, heat cycles, moisture and settling can crack tiles, wash out mortar joints and leave gaps where exhaust can leak into walls or living space.

Appliance changes make the problem more urgent. A boiler or water heater that has been replaced, or a flue now shared by different equipment, may no longer match the chimney's size or material. An oversized or damaged flue can draft poorly, which can let exhaust linger and condensation build up inside the masonry.

  • Cracked, shifted or missing clay flue tiles
  • Crumbling mortar or masonry debris collecting at the base of the chimney
  • Stains, dampness or peeling paint on walls near the chimney
  • A new boiler, furnace or water heater connected to an old flue
  • Poor draft, backdrafting or exhaust smells indoors

Oil-to-Gas Conversions and Your Chimney

Many buildings in South Williamsburg have moved, or are planning to move, from oil heat to gas. When a New York City building converts its boiler from oil to gas, 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.

We coordinate with your heating contractor so the liner suits the new appliance's size, venting needs and fuel type. Bringing us in early helps keep the chimney from becoming a last-minute obstacle in your conversion schedule.

How We Install a Chimney Liner

Every job starts with an inspection. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, and it recognizes three levels. A Level 2 inspection applies when the system changes, such as a new appliance or a switch of fuel, which describes most relining projects. If a hidden hazard has to be reached by opening part of the chimney or building, a Level 3 inspection may be needed.

Once we know the condition of the flue, we recommend a liner type and size, clean the chimney, and install the liner from the top down. We connect it to the appliance, cap the top, and confirm the system drafts properly before we leave.

  • Camera inspection of the existing flue
  • Liner sized to the appliance it will vent
  • Cleaning and debris removal before installation
  • Proper connection at the appliance and a cap at the top
  • Draft check once the work is complete

Working Around Brooklyn Buildings and the Heat Season

Tight rowhouse roofs, shared party walls and multi-story apartment buildings all affect how a liner goes in. We plan roof access, protect interior spaces near the appliance, and talk with you or your building manager about any time the heat or hot water must be off.

New York City's heat season runs from October 1 through May 31, when building owners must keep apartments heated to the city's minimum temperatures. If you manage a building, scheduling relining work in the warmer months makes the job easier for you and your tenants. If a problem shows up mid-winter, call us and we will work with you to keep the downtime short.

FAQ

Common questions

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

Common signs include cracked or missing flue tiles, masonry debris at the base of the chimney, dampness or stains near the chimney, and poor draft. A camera inspection is the most reliable way to confirm the liner's condition.

Does converting my building from oil to gas mean I need a new liner?

Not always, but often. The chimney must be evaluated during a New York City oil-to-gas boiler conversion, and many masonry flues need a new liner because gas exhaust creates acidic condensate that can corrode them.

What kind of inspection is done before relining?

Most relining projects call for a Level 2 inspection, which applies when an appliance or fuel type changes or a home is sold. A Level 3 inspection is used only when part of the chimney or building must be opened to reach a hidden problem.

Will I lose heat during the installation?

The appliance connected to the chimney usually has to be shut off for part of the work. We will tell you ahead of time and plan the job to keep the interruption as short as possible.

When is the best time to reline a chimney in Brooklyn?

Late spring and summer are usually easiest, since New York City's heat season runs from October 1 through May 31. That said, a damaged liner should be addressed whenever you find it.

Do you serve areas outside South Williamsburg?

Yes. We also install chimney liners in Clinton Hill, Fort Greene, Downtown Brooklyn, DUMBO and Boerum Hill.
