Chimney repointing in
Somerville, New Jersey
If you can scratch the mortar out of your Somerville chimney with a house key, the bond holding the brick together is gone. That is the repointing call we take most often in Somerset County.
The Somerville chimneys we work on are mostly 1880s–1920s Victorians, four-squares and early colonials, laid in soft, hand-pressed brick with a fragile fired skin. We repoint them with a soft lime-and-sand mix, or a Type O at the hardest — a rigid Portland joint transfers movement into the brick face and pops the skin off within a few winters, struck to the original weathered or grapevine profile. The usual failure pattern here: joints that crumble to sand under a house key, plus corbelled decorative courses at the top that shed mortar first.

Why Somerville chimneys lose mortar
Somerset County keeps a lot of original farmhouse and estate masonry alongside newer corporate-corridor subdivisions. Most of the brick stacks still standing in Somerville went up between the 1880s and the First World War, when chimneys were built tall, corbelled at the top and bedded in lime.
Most Somerville homes have a single interior chimney serving a fireplace and a heating appliance, so the only weathered section is what sits above the roofline — which keeps the job to a day for the majority of houses.
Because the stack is interior, water that gets past the joint in Somerville shows up as a ceiling stain in an upstairs bedroom long before anything is visible outside.
The mortar mix we use in Somerville
Ninety percent of the damage we photograph on these stacks was caused by an earlier repoint done in hard Portland mortar, not by age. 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 Somerville mix we write.
Because the exposed section is short, a top-section repoint plus a proper crown seal is often all a house here needs for the next 15 years. Every Somerville quote states the cut depth, the mix and the joint profile in writing, so you can compare it honestly against anyone else's number.
Working on Somerville roofs
Standard driveway access and a two-storey ladder set, so most jobs are in and out inside a day. Neighbours in Somerville get a heads-up the day before if we need shared driveway room.
March through November, with the busiest window right before heating season in September and October.
One of last season's Somerville jobs, off Somerset County line: a full stack repoint after a previous contractor smeared caulk over the flashing instead of fixing it. 10 courses cut back, new counter-flashing, $2,025 all in.
What Somerville homeowners report first
- a chimney that looks darker on one face after every rain

Every joint we point is warranted for ten years in writing, and the warranty follows the property to the next owner.
Watch first
Why repointing matters in Somerville
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
Somerville chimney repointing questions
- How much does chimney repointing cost in Somerville?
- Most Somerville jobs land between $925 and $2,500. A top-section repoint with a crown seal usually sits nearer $925–$1,725; a full stack above the roofline runs $1,725–$2,500. 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 Somerville chimney?
- On the housing stock here, a soft lime-and-sand mix, or a Type O at the hardest — a rigid Portland joint transfers movement into the brick face and pops the skin off within a few winters, struck to the original weathered or grapevine profile. Ninety percent of the damage we photograph on these stacks was caused by an earlier repoint done in hard Portland mortar, not by age.
- Why do chimneys in Somerville lose mortar faster than the rest of the house?
- Most Somerville homes have a single interior chimney serving a fireplace and a heating appliance, so the only weathered section is what sits above the roofline — which keeps the job to a day for the majority of houses. Because the stack is interior, water that gets past the joint in Somerville shows up as a ceiling stain in an upstairs bedroom long before anything is visible outside.
- How long does a Somerville repoint take?
- A 10-course top-section repoint on a typical Somerville home is a single day, including crown work. A full stack with flashing replacement runs two to three days. Standard driveway access and a two-storey ladder set, so most jobs are in and out inside a day. Neighbours in Somerville get a heads-up the day before if we need shared driveway room.
- 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 Somerville?
- March through November, with the busiest window right before heating season in September and October.
- Are you licensed and insured to work in Somerset County?
- Yes — New Jersey Home Improvement Contractor registered, fully insured for roof-level masonry, and working across Somerset County every week. Every joint we point is warranted for ten years in writing, and the warranty follows the property to the next owner.
