DUMBO’s chimneys are industrial artifacts. The converted warehouses and former factory buildings between the bridges vent heating plants through tall masonry stacks built for coal-era equipment — flues far larger than anything the current boilers need. In the converted lofts, exhaust from a modern gas boiler slows and cools inside those oversized passages, condenses on the walls, and eats the clay and mortar a little more every winter. The brownstone blocks toward Vinegar Hill have the same story at rowhouse scale: oil-to-gas conversions with the chimney left behind. Sweeps Chimney Services works across DUMBO with 25 years of experience — camera inspections from the boiler room to the roof, stainless-steel liners sized to the connected boiler, cleanings and repairs.

Before installing a new boiler in DUMBO
Inspect the chimney before the new boiler goes in. The camera shows the flue’s true interior size and liner condition, so the new unit gets venting matched to it — and so the warranty is never voided by a venting defect that was already in the stack. For converted buildings with oversized flues, the liner is what lets the new boiler vent the way it was designed to.
Pricing
Chimney cleaning in Brooklyn starts at $199. Inspection Level 1 starts at $99; Level 2 with camera starts at $199. Stainless-steel liner installation starts at $3,000 including labor and materials. Basic accessible repairs start at $500.
Frequently asked questions
Why are DUMBO’s converted-building flues so often oversized?
They were built for the heating plants of the industrial era — much larger equipment than today’s boilers. Exhaust from a modern boiler moves too slowly through that much cross-section, cools, and condenses. A stainless liner sized to the current plant restores proper exhaust velocity.
Can you inspect a flue in a mixed-use building?
Yes. We coordinate with building management for boiler-room and roof access. The inspection itself is the same seven-point camera run, and the written report works as documentation for boards, managers and insurers.
What does a Level 2 inspection include that Level 1 doesn’t?
The camera. Level 1 is a visual check of accessible areas; Level 2 runs an endoscopy camera the full length of the flue — inside the liner, around offsets, up to the roof — with photos and a written report. Anything involving a boiler, a conversion, or a suspected liner problem calls for Level 2.
How fast can you come out for a heating problem?
We answer 24/7, calmly and without pressure. During heating season, inspection slots fill fast — booking before the rush gets you a calmer schedule and a pre-winter fix instead of an emergency call.
