For our homeowner's insurance, we needed proof. They did a full check with photos and video, cleaned the flue, fixed some small problems with the mortar, and sent a professional report the same day. The insurance company agreed to cover…
Chimney sweep and repair in Union City, NJ
Union City is the densest of the five Hudson County cities we serve, built out almost entirely in rowhouses and small apartment buildings rather than single houses — only about one home in thirteen stands alone. Close to a third of that stock predates 1940, and it was largely converted off oil and coal heat decades ago; today barely one household in thirty-five still burns oil.

The short answer
In Union City we sweep and inspect brick chimneys in rowhouses and small apartment buildings, check flue sizing where an old chimney now vents a much smaller gas appliance, and clean dryer vents and ducts across the city’s mostly rented housing stock.
What we find on Union City jobs
Union City’s housing is old and almost entirely multi-unit — nearly a third of it predates 1940, and the great majority of what is here sits in buildings of two units or more rather than standing alone. That combination shaped the fuel history too: fuel oil has nearly disappeared as a primary heat source, and most of what remains from the older construction now vents a gas appliance through a flue that was originally built for something bigger. When that happens, the exhaust cools faster than it did with the old fuel, water condenses before it clears the roofline, and the condensate is acidic enough to work on mortar joints and any clay tile liner over time. Because so much of the city’s stock is multi-unit, a single masonry stack here often carries more than one flue inside it, one per unit or per appliance, and we run a camera up each opening rather than assume which flue belongs to which apartment before recommending any repair.

Excellent communication throughout the process. I received a text when the tech was on his way, and he arrived exactly when promised to do the sweep.
After it rained a lot, we saw wet spots on the wall next to the chimney. A broken crown and worn-out flashing were found by the team. They put in new lead boots instead of flashing, poured a new sloped crown, sealed all the joints, and…
Questions from Union City
My Union City building has one brick chimney for several apartments — does each unit have its own flue?
Often yes, even though it looks like a single chimney from the street — older Union City buildings commonly ran a separate flue per unit or per appliance inside one masonry stack. We check each opening with a camera to confirm which flue is which before recommending any work.
We’re renting in Union City — can we request chimney or dryer vent service ourselves?
You can call and describe what you’re seeing, but the property owner or manager typically needs to authorize and pay for the work on a rented unit. We’re glad to talk through what we find so you have something concrete to bring to them.
Our building still has an old oil-era chimney now venting a gas unit — is that a problem?
It can be. A flue built for an oil burner is usually larger than a modern gas appliance needs, so the cooler gas exhaust can condense on the way up instead of clearing the top. We check the liner and sizing on inspection rather than assume the old chimney is still a fit.
Where do I go for a construction permit in Union City?
The Union City Building Department at 3715 Palisade Avenue handles construction permits for the city. What actually needs a permit depends on the scope of the work, and we’ll tell you plainly what your specific job requires once we’ve had a chance to see it.
