The short answer

Most chimney repairs in Prospect Heights involve water damage to brick and mortar, failed crowns or flashing, and flue liners that need replacing, especially after a boiler is converted from oil to gas. EverSafe Chimney Sweep's certified technicians inspect the chimney first, then repair the masonry, crown, flashing, cap or liner that is causing the problem.

Prospect Heights has a large share of older masonry homes, including brownstones, brick rowhouses and pre-war apartment buildings. Many of their chimneys have taken decades of freeze-thaw cycles, rooftop water and changes in heating equipment. EverSafe Chimney Sweep repairs chimneys in Prospect Heights from our office in Fort Greene, about a mile northwest. We start with an inspection so we know what is actually wrong. Then we explain the repair options in plain terms and fix the problem at its source rather than covering it up.

Common chimney problems in Prospect Heights homes

Most chimneys in the neighborhood are brick and rise from flat roofs shared along a row of attached houses. That setup leaves the top of the chimney exposed to wind and standing water. Over time, water gets into the mortar joints, freezes and pushes the brick apart. The damage usually shows up first at the crown and in the upper courses of brick, and it often leaks into the top-floor ceiling before anyone notices anything on the roof.

Inside the chimney, older clay tile liners can crack or shift. Some flues were built with no liner at all. In multi-unit buildings, a single chimney may serve a boiler and a water heater, so the liner has to suit the appliances it actually vents.

  • Cracked or crumbling chimney crowns
  • Loose, missing or eroded mortar joints
  • Spalling brick, where the face of the brick flakes or pops off
  • Leaking flashing where the chimney meets the roof
  • Missing or rusted chimney caps that let in rain and animals
  • Cracked, deteriorated or missing flue liners
  • Damaged or stuck dampers on fireplace chimneys

How we approach a chimney repair

Every repair starts with an inspection. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. It describes three levels of inspection. A Level 1 inspection fits a chimney where nothing has changed. A Level 2 inspection is used when the system changes, such as a new appliance or a switch of fuel, or when the home is being sold. A Level 3 inspection is reserved for hidden hazards that can only be reached by opening part of the chimney or the building.

After the inspection, we show you what we found, including photos where we can take them. We explain which repairs deal with safety or active leaks and which can be planned for later. Masonry work is done with mortar suited to older brick, because mortar that is too hard can trap moisture and damage the brick around it. Crown repairs, flashing, caps and liners are matched to your chimney's size and to the appliances it serves.

Oil-to-gas conversions and flue liners

Many buildings in Prospect Heights have moved, or are moving, from oil boilers 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, and that condensate can corrode a masonry flue from the inside.

If you are planning a conversion, it helps to bring us in early. We can inspect the existing flue, tell you whether a liner is likely to be needed, and coordinate with your heating contractor so the chimney work doesn't hold up the boiler installation.

Timing repairs around the heating season

New York City's heat season runs from October 1 through May 31. During those months, building owners must keep apartments heated to the city's minimum temperatures. A chimney that has to be taken out of service for a liner or major masonry repair in mid-winter can leave a building owner in a hard spot.

For owners of rowhouses and small apartment buildings, late spring and summer are usually the easiest times for larger chimney repairs. Leaks and safety problems shouldn't wait, though. If you see water damage, smell exhaust, or notice brick falling from the chimney, call us as soon as you can.

FAQ

Common questions

How do I know if my chimney needs repair?

Common signs include water stains on ceilings or walls near the chimney, loose or flaking brick, mortar crumbling out of the joints, a cracked crown, and debris or tile pieces falling into the fireplace or boiler cleanout. An inspection is the reliable way to confirm what needs fixing.

Why is my brownstone leaking near the chimney?

Leaks near a chimney usually come from failed flashing, a cracked crown, a missing cap, or water soaking through worn mortar and brick. We trace where the water is getting in before recommending a repair.

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

Often, yes. When a New York City building converts from oil to gas, the chimney has to be evaluated. A new liner is frequently needed because gas exhaust creates acidic condensate that can corrode a masonry flue.

What inspection do I need before a chimney repair?

It depends on the situation. Under NFPA 211, a Level 1 inspection fits an unchanged system. A Level 2 inspection is used after a change such as a new appliance or fuel switch, or when a home is sold. A Level 3 inspection is used when a hidden hazard requires opening part of the chimney or building.

When is the best time to schedule chimney repairs?

Late spring and summer are usually best for larger repairs, before New York City's heat season starts on October 1. Active leaks, falling brick and venting problems should be addressed right away.

Are your technicians certified?

Yes. Our chimney repair work is done by certified technicians.
