The short answer
A chimney sweep in Prospect Heights removes soot, creosote and blockages from the flue and checks the chimney's condition while the technician is there. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, so most homes should book a sweep and inspection annually, ideally before the heating season starts.
Prospect Heights is full of brownstones, rowhouses and pre-war apartment buildings, and most of them were built with masonry chimneys. Some still serve working fireplaces on the parlor floor. Others vent a boiler or furnace in the basement. A few were sealed decades ago and are now being reopened. In every case, the flue collects soot, creosote, debris and sometimes nesting material, and it needs regular cleaning and a careful look inside. Our certified technicians come from our Clinton Hill office, about a mile north. We sweep the chimney, check its condition, and explain what we find in plain terms.
What a Chimney Sweep Includes
A sweep is more than running a brush up the flue. Our goal is to leave the chimney clean and to tell you whether it is safe to keep using as it is. We protect the room first, then clean from the bottom, the top, or both, depending on how the chimney is built and how the roof can be reached.
Before we leave, you'll know what was removed and what condition the flue is in. If anything needs attention, we tell you what it is and why it matters.
- Drop cloths and a sealed vacuum system to keep soot out of the living space
- Brushing the flue, smoke chamber, smoke shelf and firebox
- Removing creosote buildup, debris, and nests or leaves
- Checking the damper, liner and visible masonry for cracks, gaps or deterioration
- Looking at the chimney cap and crown from the roof when access allows
- A plain-language rundown of what we found, with photos when they help
Older Brownstone and Rowhouse Chimneys
Many Prospect Heights rowhouses share walls with their neighbors, and chimney stacks often run alongside the flues of adjoining houses. Original fireplaces may have clay tile liners, damaged liners, or no liner at all. Over the years, mortar joints wear down and tiles can crack. A cracked liner can let heat and smoke reach the surrounding structure.
Owners often want to bring back a fireplace that has sat unused for years. Before lighting a fire in a reopened fireplace, have it swept and inspected. Old flues can hold debris, collapsed brick or animal nests, and the liner may not be fit for use without repairs.
Boiler and Furnace Flues, and Oil-to-Gas Conversions
Plenty of chimneys here never see a wood fire. They vent a boiler or furnace. These flues still need cleaning and inspection, because soot, scale and debris can restrict the draft and push exhaust back into the building.
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. If your building is planning a conversion, we can sweep and evaluate the chimney so you know where it stands.
New York City's heat season runs from October 1 through May 31. During that time, building owners must keep apartments heated to the city's minimum temperatures. Scheduling chimney work in late summer or early fall helps keep the heating system running when tenants depend on it.
Time for your annual chimney check?
Annual Inspections and the NFPA 211 Standard
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. Chimney professionals use three inspection levels. A Level 1 inspection fits when nothing about the system has changed. A Level 2 inspection applies when the system changes, such as a new appliance or a switch of fuel, or when the home is sold. A Level 3 inspection is used when a hidden hazard can only be reached by opening part of the chimney or building.
For most Prospect Heights homes, an annual sweep paired with a Level 1 inspection is the routine. If you're buying or selling a brownstone, converting fuels, or adding a new stove or insert, ask about a Level 2.
