Chimney sweep and repair in Hillsborough Township, NJ
Hillsborough burns more fuel oil and more wood as primary heat than any other town we cover in Somerset County, which is unusual for a township built mostly after 1980. Most of that housing is a factory-built firebox behind a framed chase, but the older pockets around Neshanic, Flagtown and Belle Mead still hold real masonry from before the subdivisions arrived.

The short answer
We sweep and inspect the metal fireboxes and framed chases that most Hillsborough houses have, verify oil and LP flues at conversion, and handle the genuine masonry work that turns up in Neshanic and the other old village cores.
What we find on Hillsborough jobs
Hillsborough’s housing went up mostly in the 1980s and 1990s, which means the standard chimney here isn’t brick at all, it’s a UL-listed metal firebox sitting inside a framed and sided chase. The recurring finds on those jobs are corrosion working through the chase cover and water getting in around the cap, since those chimneys have no mortar to lose. Where the township still burns fuel oil, and it has more of that than anywhere else we cover in the county, the question at conversion time is whether the existing flue is sized for the smaller gas appliance going in, which is what the state’s chimney verification form is built to catch. Hillsborough also carries the highest wood-heat count in Somerset County, and that’s a different job entirely: real, sustained creosote buildup that an annual sweep is meant to keep ahead of. In Neshanic, Flagtown, Belle Mead and the other old cores, the work flips back to traditional masonry, built well before any of the lining standards this form now enforces.

What homeowners say on our Google listing
A selection of our 5-star reviews on Google.
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 Hillsborough Township
I have an oil furnace and I’m switching to gas. What happens to the old chimney?
The installer has to verify on the state’s chimney form that the flue is correctly sized and lined for the new appliance before the job closes out. An oil flue is often too large for a smaller gas unit, and if it isn’t lined for gas, that gets addressed as part of the conversion.
We burn wood most winters. How often does the flue need sweeping?
Hillsborough has the highest number of primary wood-heat households of any town we serve, and that census figure only counts wood as a main heat source, so anyone running a supplemental stove isn’t in it either. NFPA’s standard calls for an annual inspection regardless, and a household burning through a full winter usually needs the sweep that comes with it.
Do you handle chase covers, or just the fireplace itself?
Yes. Most Hillsborough houses have a metal firebox inside a framed, sided chase rather than a masonry stack, and the chase cover is exactly where we look first, since corrosion and water entry there are the recurring problem.
Our house is in one of the old sections near Neshanic. Is that different?
It usually is. The village cores like Neshanic, Flagtown and Belle Mead hold most of the township’s pre-1940 housing, and that’s genuine masonry built before modern lining standards existed, which is a different inspection than the framed chases in the newer subdivisions around it.
