The short answer
Chimney repair in Bensonhurst usually means fixing water damage: worn mortar joints, cracked crowns, failed flashing, and flue liners damaged by moisture or by an oil-to-gas boiler conversion. GoldenFlue inspects the chimney first, shows you what we found, and repairs the actual cause.
Many Bensonhurst homes are brick rowhouses, two-family houses, semi-attached homes and pre-war apartment buildings, and most of them have masonry chimneys that have been through decades of freeze-thaw winters and at least one change in heating system. When a chimney starts leaking, dropping bits of brick or mortar, or venting poorly, the repair has to fit what is actually wrong. GoldenFlue Chimney Services repairs chimneys throughout Bensonhurst from our office in Bay Ridge, about 2 miles to the west. Our certified technicians find the cause first, explain it in plain terms, and then fix it.
Chimney problems common in Bensonhurst homes
In attached rowhouses, chimney stacks often sit at or near the party wall. Sometimes a stack is shared with the house next door. Water that gets into the masonry can travel, so a leak may show up as a stain on a top-floor ceiling, a damp patch beside the fireplace, or peeling paint on the wall you share with a neighbor. Flat roofs are common on these blocks, and the joint where the roof meets the chimney can hold standing water, so worn flashing is one of the most frequent causes we find.
Detached and semi-attached homes often have a chimney running up an exterior side wall. These chimneys get the full force of wind-driven rain and repeated freezing and thawing. Over time, water soaks into the brick, freezes, and pushes the face of the brick off. This is called spalling, and it is often the first thing homeowners notice.
Chimney repairs we handle
Most repairs fall into a handful of categories. We tell you which ones apply to your chimney and which can wait.
- Repointing: grinding out cracked or missing mortar and packing in fresh mortar so water stops getting into the joints
- Brick replacement for spalled or broken units, matched as closely as practical to the existing brick
- Crown repair or rebuilding: the concrete cap on top of the masonry that sheds water away from the flue
- Flashing repair or replacement where the chimney meets a flat or pitched roof
- Chimney caps to keep out rain, birds and debris
- Flue liner repair and relining, including stainless steel liners for gas appliances
- Damper repair and smoke chamber parging for working fireplaces
Oil-to-gas conversions and chimney liners
Many Bensonhurst buildings that once burned oil now heat with gas. In New York City, the chimney has to be evaluated as part of an oil-to-gas boiler conversion. A new liner is often needed because gas exhaust produces acidic condensate that can corrode a masonry flue. Signs of that damage include crumbling tile or mortar at the base of the flue, white staining on the chimney, and water dripping at the boiler connection.
If you are planning a conversion, or already converted and never had the flue checked, we can evaluate the chimney and size and install a liner suited to the new appliance.
We inspect before we repair
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. It describes 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 of fuel, or when a home is sold. Level 3 applies when a hidden hazard can only be reached by opening part of the chimney or building.
Before quoting a repair, we look at the crown, flashing, masonry and flue and tell you what we see. When the problem is on the roof or inside the flue, we show you with photos or camera footage so you are not taking our word for it.
Plan repairs around heat 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. If you own a two-family house or a small apartment building, any chimney repair that takes the boiler offline is far easier to schedule between June and September. Warmer months are also better for masonry work, because fresh mortar needs mild temperatures to cure properly.
Active leaks and venting problems should not wait for summer. Call us as soon as you notice them.
