A chimney rarely fails all at once. It tells you in pieces. A brown stain near the ceiling after a storm. A line of mortar gone soft and sandy. White crust streaking the brick once the rain dries. Any one of those means water is already getting in, and on Union's older Colonials and postwar homes it has a long way to travel before you see it. We handle chimney repair in Union NJ as a roofing-and-masonry job, not just a brick job, because on these houses the trouble usually starts at the seam where the chimney meets the roof.
Flashing Read First
We start at the flashing line, since that is where the leak evidence almost always leads on a Union roof.
A Few Minutes Out
The shop sits just up the Parkway in Clifton, so a crew and a load of matched brick reach Union Center or Vauxhall fast.
Licensed, Insured, Warrantied
NJ Lic. #13VH11720500, a fair number after a free look, and a 2-year workmanship warranty in writing.
The Leak Is Usually the Flashing
Here is the part most homeowners never get told. The thing they call a chimney leak usually starts where the chimney passes through the roof, not in the brick at all. The flashing along that joint lets go, water tracks in behind it, and the stain lands on the plaster near the stack. Brick takes the blame. A masonry quote shows up. The drip keeps going.
When it really is the flashing, the fix is a flashing and seal job, not a rebuild. And we do that flashing in metal, woven into the shingle courses, never smeared in tar that cracks by the second winter. If the masonry is the actual culprit, you see the photos that say so. You pay for the real problem either way.
Step and Counter Flashing, Done in Metal
A chimney needs two layers of metal at the roofline to stay dry. Step flashing tucks under each course of shingle along the sides. Counter flashing sets into a cut groove in the mortar and laps down over the step pieces, so water has nowhere to sneak. On Union's mix of steep older roofs and postwar pitches, that detail does a lot of work, and a lot of work is exactly what a tar patch cannot do for long. Tar shrinks, splits, and pulls away from brick. We cut the counter flashing into the joint, bed it, and let the metal do the sealing the way it was meant to.
Crown, Cap, and the Mortar Joints
The crown is the slab of concrete on top that throws rain off the flue. Crack it through and water runs straight down inside the stack. The cap covers the flue opening and keeps weather, leaves, and squirrels out. The mortar joints are the wall's own defense, and Union's winters chew on them. We repoint when the joints have washed back, grinding out the soft mortar and packing fresh in to match. A free inspection tells you which of the three is actually failing instead of selling you all of them.
Older Brick and the Freeze-Thaw Problem
Union built up in waves, and the chimneys reflect that. The township goes back to 1808, when it was still farm country known as Connecticut Farms, and a few genuinely old structures survive, like the Connecticut Farms Presbyterian Church that dates to 1730. Then came the early-1900s growth around Union Center, and after the war the manor and estate subdivisions filled in, places like Putnam Manor, Larchmont Estates, and Orchard Park. The older the brick, the more it drinks water. When that water freezes it pushes, and the face of the brick pops off in flakes, a thing masons call spalling. Once a stack starts spalling the clock is running, and the fix is easier the sooner somebody looks.
Why Roofing Plus Masonry Beats Either Alone
This is the whole reason we work the way we do. A chimney problem lives in two trades at once. The leak might be flashing, which is roofing, or it might be a cracked crown and washed joints, which is masonry, and very often it is both feeding each other. A shingle-only roofer caulks over a real crown crack. A masonry-only outfit repoints beautifully and never touches the flashing that was the actual leak. We carry both crews and both materials, so the diagnosis does not stop at the edge of one trade's comfort zone. One contractor looks at the entire stack and tells you the truth about all of it.
What Union Does to a Chimney
Union sits in the open suburban stretch of Union County, where homes catch the full run of a North Jersey winter. The pattern that wrecks a chimney is freeze-thaw. Water soaks the brick in a November rain, freezes hard in January, and by March the faces are letting go. Wind-driven rain off a nor'easter works at any loose cap or lifted flashing, and on the steeper older roofs around Union Center ice damming piles up at the eaves and backs water uphill toward every flashing seam, the chimney's included. The postwar Capes and ranches in the Putnam and Larchmont sections have their own version of the problem, where aging asphalt and tied-in additions leave flashing gaps right beside the stack. Caught early, nearly everything on a chimney is a small repair instead of a rebuild.
The Failure Order, From the Top Down
Chimneys give out in a sequence. The cap goes first. It is thin metal against weather and it loses. The crown cracks next, freeze-thaw splitting that concrete slab and opening the stack to rain from above. Then the flashing at the roofline, which is the leak everybody blames on brick. Last comes the masonry, joints washing out and brick faces spalling, by which point water has been working inside the wall for years. Where your chimney sits in that order is exactly what the inspection pins down, and it decides whether you are looking at an afternoon's repair or a real rebuild.
A Union Chimney Calendar
The seasons run a chimney through the same loop every year. Fall rain loads the brick with water. January and February freeze it and crack what is already weak. Spring is when the damage shows, suddenly and all at once, which is why so many Union homeowners call in April convinced the chimney aged a decade over the winter. It did not. It just hid the wear until the thaw revealed it. Nor'easters from October through April are the other test, throwing wind-driven rain at the stacks. If you do one preventive thing, get the crown and flashing sealed before the cold sets in. February is when we meet the chimneys nobody checked.
When a Rebuild Is the Honest Answer
Some stacks are past saving. Mortar gone across the whole chimney, brick faces popping in sheets, a lean you can read from the sidewalk. Repointing that just takes your money to buy a year before the rebuild you already needed. When a stack has crossed that line we say it, with photos in your hand, and the rebuild conversation starts with itemized pricing, brick matched as close as old brick allows, and a proper new crown on top. Most Union chimneys are not there yet. The free inspection sorts the salvageable from the spent, honestly, without talking you into the bigger job.

Chimney Repair FAQs for Union
What does chimney repair run in Union?
You get a written number before anyone lifts a trowel, scaled to what the inspection finds. Flashing and repointing land at the affordable end. A rebuild is a separate, honest conversation.
Why is there water in my fireplace after it rains?
Usually a failed cap or a cracked crown letting rain straight down the flue. Both are quick fixes once we confirm which one it is, and we confirm by looking, not guessing from the yard.
You found the leak is flashing. Tar or metal?
Metal, always. Step and counter flashing cut into the joint and woven into the shingles. Tar is a patch that cracks by the next freeze. We do not sell it.
How long does repointing hold up?
Decades, done right. The new mortar gets matched to the original in hardness as much as color, which is what keeps it from quietly destroying old brick.
Can you do the chimney while you do my roof?
Yes, and it is the smart move. The flashing seam gets built as one system and you skip paying to set up twice.
Do you sweep chimneys too?
We are masonry and flashing, not sweeps. For creosote cleaning we will hand you a sweep we trust and coordinate when a job needs both trades.
My stack is leaning. Emergency?
Treat it like one. A visible lean means the structure is going. Keep people clear of where it would fall and call us. Decisions about bracing or partial rebuild need eyes on it fast.
Can you match the brick on an older Union home?
Close enough that a neighbor will not catch it. We pull a sample and match size, color range, and joint style. A flawless match of decades-old brick is not real, and anyone promising one is selling.
Getting to Your Block
Union Center
Morris Avenue through the older heart of town, where the early-1900s housing stock carries the tall original stacks.
Vauxhall and Five Points
Across the Vauxhall section and out to the Five Points crossing where Morris Avenue meets the main routes.
Putnam Manor and Larchmont Estates
The postwar manor and estate subdivisions where Capes and ranches need flashing and crown work most.
The Roads We Run
Morris Avenue, which carries Route 82 through town, is the main artery, and it puts a crew on almost any Union street quickly from the Clifton side. We come down the Garden State Parkway and cut over on Route 22 or Interstate 78, so reaching Union Center, Battle Hill, or Green Lane is a short run. The shop being minutes north is why a same-week look is normal.
Union's Chimney Mix
The chimneys here sort roughly by the age of the house under them. The older homes around Union Center carry tall solid-masonry stacks, the kind built when every house got a real chimney, and they show the classic crown-and-flashing failures of their years. The postwar Capes, ranches, and colonials out in the manor and estate sections run shorter chimneys, often with a furnace flue doing daily work the fireplace never demanded, which means the inside of the flue matters as much as the brick you can see. And here and there a stack has been abandoned entirely after a heating change, left to take weather with nobody watching it. We work on all of them. The first job of the assessment is telling you which kind you actually own, because owners guess wrong about that more often than you would think, and the right fix turns entirely on the answer.
The previous owner closed off the fireplace. Does the chimney still need anything? The brick does. A sealed flue still takes weather on the outside, and an abandoned stack with a cracked crown quietly soaks the wall under it for years. Cap it, seal the crown, and the retired chimney stays put.
Can you line the chimney work up with a roof job? Honestly the best time. Staging is already up, the flashing is already open, and the two trades meet right at the joint that leaks. Bundling them saves real money and a second round of ladders on the lawn.
