Chimney repointing in
Hillside, New Jersey
Failed mortar joints are the number one cause of chimney water damage in Hillside. Grinding out and repointing stops the leak at a fraction of the cost of a rebuild.
The Hillside chimneys we work on are mostly 1920s–1940s brick colonials, tudors and two-family homes, laid in dense machine-made brick with a hard fired face. We repoint them with Type N tinted to match the original buff or grey joint, struck to the same concave profile the original mason used. The usual failure pattern here: open head joints in the top five courses and a hairline-cracked crown that funnels water straight into the stack.

Local conditions
Why Hillside chimneys lose mortar
Union County mixes industrial-era row housing with some of the state's best-preserved Victorian districts, so mortar specs here vary street to street. Hillside filled in through the 1920s and 1930s, and those chimneys were built with the first generation of Portland-blended mortar — durable, but rarely repointed since.
Dense blocks in Hillside mean shared walls, tight setbacks and party-wall chimneys. Access, not the masonry, is usually what sets the price — we often stage from the roof rather than the ground.
Chimneys in Hillside sit in the lee of taller buildings, which concentrates driven rain onto one face and leaves the other bone dry.
The mortar mix we use in Hillside
These stacks usually have one good repoint left in them before the brick itself becomes the problem. The old joint comes out with a dust-shrouded angle grinder and hand finishing at the corners, so no brick arris gets clipped. A mortar that is harder than the brick will always destroy the brick, which is the single rule behind every Hillside mix we write.
We work with dust-controlled grinders and full drop cloths, and we handle the permit paperwork where the municipality requires it for roof-level masonry. You get the full roof-level photo set from your Hillside inspection whether or not you hire us.
Working on Hillside roofs
Street parking, alley access and neighbour notice are part of the quote here, not an afterthought. Hillside jobs are scheduled in half-day blocks so you are not waiting in all morning.
City crews run Monday to Saturday, and we schedule around street-parking rules so the block isn't disrupted.
A recent example: a North Hillside homeowner in Hillside called about a bedroom ceiling stain. The top 4 courses had open head joints on the weather face; we ground them out, repointed and sealed the crown for just under $1,400. The stain never came back.
What Hillside homeowners report first
- a cracked or missing crown wash on top of the stack
- vegetation or moss growing out of an open joint
- loose bricks at the very top course you can rock by hand
- a damp patch on the ceiling or wall next to the chimney breast
- sand and mortar crumbs collecting on the roof or in the gutters
What the free Hillside inspection covers
- the flue liner top for cracks and displaced tiles
- every joint on all four faces, photographed close up
- the top courses for plumb and any shift in the corbel
- the rain cap, damper and any prior sealant work
- the smoke chamber and firebox for water staining
If a joint we pointed fails inside ten years we come back and redo it — no argument, no charge.
Watch first
Why repointing matters in Hillside
Twenty seconds on the thing most homeowners miss: the brick is fine, the mortar between it is not. Water gets into an open joint, freezes, expands and takes the joint apart — one winter at a time.

Straight answers
Hillside chimney repointing questions
- How much does chimney repointing cost in Hillside?
- Most Hillside jobs land between $850 and $2,250. A top-section repoint with a crown seal usually sits nearer $850–$1,550; a full stack above the roofline runs $1,550–$2,250. Stack height, roof pitch and how many faces have failed are what move the number, and your written price is fixed before we start.
- What mortar should be used on a Hillside chimney?
- On the housing stock here, Type N tinted to match the original buff or grey joint, struck to the same concave profile the original mason used. These stacks usually have one good repoint left in them before the brick itself becomes the problem.
- Why do chimneys in Hillside lose mortar faster than the rest of the house?
- Dense blocks in Hillside mean shared walls, tight setbacks and party-wall chimneys. Access, not the masonry, is usually what sets the price — we often stage from the roof rather than the ground. Chimneys in Hillside sit in the lee of taller buildings, which concentrates driven rain onto one face and leaves the other bone dry.
- How long does a Hillside repoint take?
- A 4-course top-section repoint on a typical Hillside home is a single day, including crown work. A full stack with flashing replacement runs two to three days. Street parking, alley access and neighbour notice are part of the quote here, not an afterthought. Hillside jobs are scheduled in half-day blocks so you are not waiting in all morning.
- Do I need repointing or a rebuild?
- If the brick is sound and only the joints are soft, repointing is the right fix. We recommend a rebuild only when brick faces have spalled through or the top courses are out of plumb — and either way you get the roof-level photos that show why.
- When is the best time to repoint in Hillside?
- City crews run Monday to Saturday, and we schedule around street-parking rules so the block isn't disrupted.
- Are you licensed and insured to work in Union County?
- Yes — New Jersey Home Improvement Contractor registered, fully insured for roof-level masonry, and working across Union County every week. If a joint we pointed fails inside ten years we come back and redo it — no argument, no charge.
