Chimney sweep and repair in Union County, NJ
Elizabeth and Plainfield are Union County’s two oldest cities, built up before most of New Jersey owned a car, and the housing shows it: two-family and multi-unit buildings are the norm in both. Gas heats the overwhelming majority of households in each city now, but the flues themselves mostly predate that fuel, and a real minority of homes still burn oil.

The short answer
We sweep, inspect and repair chimneys, and clean ducts and dryer vents, across Elizabeth’s and Plainfield’s older two-family and multi-unit housing stock, work that in this county means checking a shared flue as often as a single household’s.
What we find across Union County
Both of Union County’s service cities are old and dense by New Jersey standards, and the chimney work follows the housing stock rather than the calendar. In Elizabeth, 86 percent of housing sits in buildings of two units or more, with two-unit properties the single largest category. A shared masonry stack serving two households’ appliances is the normal condition there. Gas heats 85.7 percent of Elizabeth’s households and 76.0 percent of Plainfield’s, but in both cities the housing predates that shift, so an atmospheric gas appliance is often venting into a flue laid out for something else. Plainfield keeps more of its oil heat, 618 households, more than double Elizabeth’s share, and adds a documented case of what happens when nobody checks a rental building for years: the 2023 condemnation of 49 units on West 7th Street over uncapped gas conductors, which pushed the city into requiring an annual fire-and-safety inspection on every rental unit. Elizabeth and Plainfield each run their own construction office, and neither defers to the county.

Work was carried out by an expert who knew just what proportions of air to fuel were required for a brick fireplace system to burn cleanly.
It was no longer a strong pick. The service fixed the damper and got rid of the sticky creosote. Now it's easy to start fires and they burn constantly. Every time we light it, we can see the difference.
Top-notch service! They showed up right on time, which is rare these days. The technician took the time to explain everything and showed me exactly how much soot was clogging the flue. Fast, clean, and very reasonably priced. I will definitely be using them every year from now on!
Questions from Union County
Do you work in Union County, or just Readington?
Union County is part of our regular coverage. We currently serve Elizabeth and Plainfield, sweeping and repairing chimneys and cleaning ducts and dryer vents in both cities’ older two-family and multi-unit housing. If your Union County address is in another town, call and ask. We can usually tell you quickly if it’s within range.
What’s different about a Union County job compared to a Hunterdon one?
The housing is older and denser. Two-family and multi-unit buildings are the norm in both Elizabeth and Plainfield, so a chimney or duct job here more often serves more than one household, and the person who calls isn’t always the one who owns the building.
Do I need a permit for chimney work in Elizabeth or Plainfield?
Likely, and it’s handled at the city level in both cases. Elizabeth’s Construction Department and Plainfield’s Building & Construction Division each issue their own chimney and mechanical permits under the state’s Uniform Construction Code. Union County itself has no separate permit office for this work.
