Greenpoint’s chimneys tell the neighborhood’s industrial history. The brick rowhouses along Manhattan Avenue, the converted factory lofts near the East River waterfront, the wood-frame homes on the side streets — most heat with boilers venting through masonry flues built for coal or early oil heat, long before the current gas boiler was installed. Oil-to-gas conversions are the quiet problem here: cooler gas exhaust condensing inside oversized clay flues, dissolving mortar and cracking terra cotta tiles year after year. Sweeps Chimney Services works across Greenpoint with 25 years of experience — camera inspections from the boiler room to the roof, stainless-steel liners sized to the boiler, cleanings and repairs done right.

Before installing a new boiler in Greenpoint
Inspect the chimney before the new boiler goes in. A camera inspection shows the flue’s true interior size and liner condition, so the installer matches the venting to the boiler — and so the equipment warranty is never voided by a venting defect that predated the installation. In Greenpoint’s converted buildings, one correctly sized stainless liner usually resolves the whole venting picture for decades.

Frequently asked questions
Do Greenpoint’s converted lofts have different chimney problems than rowhouses?
Often, yes. Converted industrial buildings run larger heating plants through tall stacks sized for a different era’s equipment, while rowhouses have narrow party-wall flues. Both suffer the same oil-to-gas condensation damage — the camera inspection is what reveals which pattern your building follows.
My boiler was converted from oil to gas years ago — is the chimney still at risk?
The damage is cumulative. Acidic condensate from gas exhaust keeps attacking clay and mortar every heating season, so a conversion from ten years ago can produce a failing liner today. If the flue was never camera-inspected after the conversion, it is worth checking now.
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.
Will a new liner change how my boiler runs?
It should run better. A correctly sized liner restores proper draft — cleaner combustion, less sooting of the burner and heat exchanger, fewer safety shutdowns. The venting stops fighting the equipment.
