About Chimney Repair
A chimney is several parts with different lifespans stacked on top of each other. The crown and cap take the weather straight on. Flashing has to move with the roof. Mortar joints wear faster than the brick around them, and the flue lining takes heat and acid from the inside. When one part fails, it usually loads the others with water, so a repair plan starts by finding which part let go first.
Freeze and thaw drive most of the damage seen in this region. Water soaks into a crack or a soft joint, freezes overnight, swells and pushes the gap a little wider, and the next thaw lets more water in. Nor'easters push rain sideways into the side of the stack that faces the wind. Many older chimneys also carry patches of hard cement mortar or roofing tar from earlier repairs, and those patches often trap water rather than shed it.
Good repair work fixes the cause and then the damage, in that order. A leaking crown gets dealt with before the brick below it is repointed, or the new joints fail again. Materials are chosen to suit the old ones: mortar softer than the brick, brick matched in size and color, metal that will not react with masonry. And the work is described before it starts, so the scope does not grow quietly once the scaffolding is up.

- A written list of repairs in the order they should be done
- Roof, plantings and walkways protected under the work area
- Cracks, joints, brick, crown or flashing repaired as listed
- Mortar mixed to suit the existing brick rather than the strongest mix on the truck
- Debris cleared from the roof, gutters and yard
- A walk-through of the finished work and what to watch afterward

- Brick faces flaking or popping off
- A cracked or chipped crown

How the Job Goes
- Find the cause
We look for where water enters, not just where it shows up.
- Written estimate
You get a clear, free written estimate with no hidden fees.
- Repair
Our own crew does the work, with matched brick and mortar where it shows.
- Clean finish
We clean up the roof, the yard and the room before we leave.
Your Options
For hairline cracks and small gaps in a chimney that is otherwise sound. Quick and affordable, but it only lasts if the masonry around it is solid.
Failed joints ground out and refilled, and spalled bricks swapped out. The usual fix when the damage is spread across the stack but the chimney stands straight.
The top section taken down to sound masonry and laid back. Chosen when the upper courses are loose or leaning and patching would not hold.
What Affects the Cost
- Which parts need work and how many repairs are combined in one visit
- Scaffolding or roof brackets, which depend on how tall the stack is and how steep the roof
- How far the damage goes once the old mortar or crown is opened up
- Finding brick and mortar that match an older house
- Removing earlier tar or cement patches before a proper repair can start
- Permits or building department filings where the town or city requires them
Every job starts with a free written estimate, so you know the price before we start.
When It Cannot Wait
- Bricks or pieces of crown falling onto the roof, a walkway or a neighbor's property
- A stack that has started to lean or has a crack you can see from the street
- Water running inside a wall or through the ceiling during rain
- Cracked flue tile in a flue that a boiler or water heater uses every day
Make It Last
- Keep a cap on every flue so rain does not run straight down the inside
- Have the crown and flashing looked at each year, since small cracks there feed every other problem
- Keep gutters near the chimney clear so water does not back up against the brick
- Apply a breathable water repellent once repairs have cured, if the brick absorbs water readily
- Avoid roofing tar on brick: it cracks, hides the problem and traps water

Guides From Our Crew
What Do Cracks in a Chimney Mean?Chimney cracks mean different things depending on where they are, which way they run and whether they are growing.
How Much Does Chimney Repair Cost?Chimney repair cost comes down to what is broken and how hard it is to reach.
Does Homeowners Insurance Cover Chimney Repair?That depends on what caused the damage and on the wording of your own policy.
Who Is Responsible for Chimney Repair?The owner of the building is usually responsible for the chimney itself, since it is part of the structure.
Philadelphia Row House Chimneys: Common ProblemsPhiladelphia row house chimneys tend to fail in the same few ways: worn mortar on short stacks above flat roofs, leaks where the roof coating meets the brick, unlined flues serving a boiler or water heater, and stacks left too short when the house next door adds a floor.
Do You Need a Permit for Chimney Work in NYC?It depends on the job.
