The oldest chimneys in the county
Belvidere and Phillipsburg share a median house from 1938, and in both towns 76 percent of homes went up before 1960. Oxford has 41 percent of its homes from before 1940. Brick chimneys from those years have been through a lot of freezing and thawing, and the top courses, which take weather on all four sides, go first.
Oil adds to it. Half of Belvidere's homes heat with oil, and in Pohatcong, where the median house dates to 1956, 62 percent do. Boiler exhaust leaves soot and condensed moisture in the flue, and the top of the stack can wear out while the brick lower down still looks fine.
At some point the joints are empty most of the way through and the crown is cracked from edge to edge. Fresh mortar cannot fix that. The stack comes down until we reach solid brick, then goes back up, and the flue gets a proper look while it is open.
You see the photos from the top before anyone says the word rebuild, including where the sound brick begins.

How we decide a Warren County chimney needs rebuilding
A rebuild is the bigger job and the bigger bill, so we only recommend one when the brick above the roof cannot take new mortar.

At the top, we check
- Whether the upper courses rock or shift by hand.
- A crown cracked from one edge to the other.
- How deep the mortar has washed out, course by course.
- A lean, or a gap opening between the stack and the house.
- Soot, cracks and gaps in the liner, as far down as we can see.
- What still uses the flue: an oil boiler, a wood stove, a water heater, or nothing.

Sometimes only the crown and the top few courses need work. When a smaller job will hold, that is the one on your estimate. Chimney repair in Warren County
How a chimney rebuild works in Warren County
How long it takes depends on how far down the stack has to come. All seven steps are on the chimney rebuilding page.
Free inspection
We get up to the top when it is safe to and photograph the brick, crown, cap, flue and flashing. You see how far the damage goes before we talk about price.
Written estimate
How far down we expect to go, what goes back up and the price, on paper. Any permit goes on it too.
Down to solid masonry
We take the chimney apart brick by brick until we reach solid masonry. With the stack open, we check the liner and the framing and show you what we find.
Build it back and clean up
New brick and mortar go up course by course, with a new crown, cap and flashing. Then we haul the old brick away and go over the photos with you.




Do you need a permit for a chimney rebuild in Warren County?
It depends on your town. Rebuilding a chimney is not on New Jersey's list of ordinary maintenance or minor work, so the construction office in your town decides what paperwork it needs. Belvidere's historic district has its own review by the Historic Preservation Advisory Commission, but maintenance of existing roof material and in-kind siding replacement are exempt. We check with your town before we start, and any permit goes on the estimate.

- We carry insurance and can send you the certificate before work starts.
- The inspection is free, and the estimate comes to you in writing.
- We are open 24 hours.
If it is in Warren County, yes. We cover all 22 municipalities, from Allamuchy to White. Put your ZIP code in the estimate form and we confirm it when we call you back.
The construction office in your town decides. A rebuild is not on the state list of work that skips the permit process, so we ask before we start, and any permit it requires goes on the estimate.
Yes, with the town involved. Belvidere's historic district has its own review by the Historic Preservation Advisory Commission, and its exemptions cover maintenance of existing roof material and in-kind siding replacement, not chimney masonry. We check with the town before we start, and you get photos and the estimate for any review.
If it needs work, that is the time, while the stack is open. Oil exhaust leaves soot and moisture in the flue, and a cracked liner lets both reach the brick. We look down the flue before we write the estimate and list any liner work on it.
How tall the stack is, how far down it has to come, and what the flue needs. A tall chimney on a two-story house is a different job from a short one on a ranch house. We do not quote over the phone. The written price comes after we have stood at the top and seen how far the damage runs.
