The short answer

Bensonhurst homes often need a new chimney liner after an oil-to-gas boiler conversion, when an older clay flue is cracked, or when a new heating appliance is installed. GoldenFlue inspects the existing flue, recommends a liner sized to your appliance, and installs it from our nearby Bay Ridge office.

A chimney liner is the inner channel that carries smoke and exhaust gases up and out of your home. In many Bensonhurst rowhouses, two-family homes, detached houses and pre-war apartment buildings, the original clay tile liner has cracked or shifted, or it was never sized for the boiler, furnace or water heater it serves now. GoldenFlue Chimney Services installs new liners for homes and buildings throughout Bensonhurst. We work out of our Bay Ridge office, about 2 miles west, and our certified technicians handle everything from the first inspection to the final check.

Why Bensonhurst Chimneys Often Need New Liners

Much of Bensonhurst's housing is older masonry construction: attached and semi-attached brick homes, detached houses, and pre-war apartment buildings with tall shared flues. These chimneys were usually built with clay tile liners or with no liner at all. Over decades, heat, moisture and freeze-thaw cycles can crack tiles, wear down mortar joints, and leave gaps where exhaust can reach the brick or leak into the house.

Heating equipment has changed too. A modern high-efficiency boiler or water heater produces cooler exhaust, at a different volume, than the equipment the chimney was built for. A flue that is too large or in poor condition may not draft properly. Draft problems can let exhaust, including carbon monoxide, spill back into living space.

Oil-to-Gas Conversions and Your Chimney

Many Bensonhurst homes and buildings have switched, or are planning to switch, their boilers from oil to gas. In New York City, the chimney has to be evaluated as part of that conversion. A new liner is often needed. Gas exhaust produces acidic condensate, and over time it can corrode a masonry flue that was built for oil.

If you are planning a conversion, bring us in early. We can inspect the chimney and coordinate the liner work with your heating contractor's schedule. That way the new boiler is not waiting on the flue.

Liner Options We Install

The right liner depends on the appliance it serves, the fuel it burns, and the size and shape of your existing flue. After the inspection, we explain which option fits your chimney and why.

  • Stainless steel liners: the most common choice for gas and oil boilers, furnaces and water heaters. They are sized to the appliance and run down the existing flue.
  • Insulated stainless liners: for exterior chimneys or flues where keeping exhaust warm helps draft and reduces condensation.
  • Wood-burning fireplace liners: rated for the higher temperatures of a working fireplace or wood stove.
  • Cast-in-place liners: a poured lining that can also strengthen a deteriorated masonry flue, used where a metal liner is not the best fit.
  • Chimney caps and top plates: installed with the liner to keep out rain, debris and animals.

How Liner Installation Works

Every job starts with an inspection. The NFPA 211 standard calls for a Level 2 inspection when a system changes, such as a new appliance or a fuel switch, and also when a home is sold. That inspection includes a camera look inside the flue. If a hidden problem has to be reached by opening part of the chimney or wall, a Level 3 inspection may be needed.

Once we confirm the liner type and size, we clean the flue and prepare the top and base of the chimney. Then we lower the liner into place and connect it to the appliance. Last, we seal and cap the top and check that the system drafts correctly. Most of the work happens on the roof and at the appliance, so disruption inside your home is limited. We protect floors and work areas near the boiler or fireplace.

Planning Around Heat Season

New York City's heat season runs from October 1 through May 31. During that time, building owners must keep apartments at the city's minimum temperatures. If you own a two-family home or a multi-unit building in Bensonhurst, a boiler shut down for chimney work affects your tenants. Scheduling liner installation in late spring or summer gives you the most flexibility.

If a liner problem turns up in the middle of winter, we work to keep downtime short. We also serve nearby Bath Beach, Dyker Heights, Borough Park, Bay Ridge and Sunset Park.

What to expect

How a visit goes

  1. We find the cause first

    A leak, a draft problem or a smoky room can have several causes. We track down the actual source before suggesting a repair, so you are not paying for work that does not solve it.

  2. We show you what we see

    Most of a chimney is out of sight. We photograph the flue, crown, flashing and cap so you can see the condition for yourself and decide with full information.

  3. We keep your home clean

    We cover floors and furniture near the work area, contain soot and debris, and clean up before we leave.

FAQ

Common questions

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

Warning signs include crumbling tile or mortar falling into the fireplace or boiler cleanout, water stains on walls near the chimney, and exhaust smells indoors. A planned oil-to-gas conversion or a new appliance is another reason to check. A camera inspection is the reliable way to know.

Do I need a liner if I'm converting my boiler from oil to gas?

Often, yes. In New York City, the chimney has to be evaluated during the conversion. Gas exhaust creates acidic condensate that can corrode an unlined or oil-era masonry flue, so a new liner is frequently required.

How long does liner installation take?

Many single-flue jobs in a house are finished in a day. Taller flues in apartment buildings, chimneys that need repairs first, and cast-in-place liners can take longer. We give you a timeline after the inspection.

Will my heat be off during the installation?

The appliance connected to the flue has to be shut down while we work on it. We schedule the job to keep that window as short as possible. This matters most for buildings with tenants during the October through May heat season.

Can you install a liner in a shared or multi-flue chimney?

Yes. Many Bensonhurst buildings have chimneys with more than one flue. We inspect each flue and line the ones that need it, sizing each liner to the appliance it serves.

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

NFPA 211 calls for chimneys, fireplaces and vents to be inspected once a year. That applies to newly lined chimneys as well.
