Types of Chimney Masonry Repair
Mortar joints are like the grout in a shower: they're meant to wear out first so the tile, or here the brick, doesn't. On a chimney standing out in Binghamton weather, the joints near the top usually go in 25 to 40 years. Repoint them on time and the brick lasts another century. Wait, and the brick starts to go too.
This is the chimney masonry repair we do, from small to big:
1. Chimney Repointing and Tuckpointing
We grind out the old mortar about 3/4 inch deep, wash the joints and pack new mortar in two layers, then tool it to match the old joint shape. Tuckpointing is the same job with a finer finishing line; around here people use the words for the same thing.
2. Chimney Brick Repair and Replacement
Spalled brick, where the face has popped off after water froze inside it, gets cut out and replaced. We match size and color from salvage and reclaimed stock, because a bright new brick in an old stack looks like a patch for 30 years.
3. Chimney Rebuild Above the Roofline
When the top of the chimney is loose, leaning or has lost half its mortar, we take it down to solid brick, usually to the roofline, and relay it with the old brick where it's sound. A new crown and cap go on top.
4. Matching Mortar to Old Brick
Old Binghamton brick is soft. Modern Type S mortar is harder than that brick, so when the chimney moves, the brick cracks instead of the joint. We use a softer Type N or lime mortar on pre-1950 chimneys, as the National Park Service recommends for old masonry.
5. Chimney Leaning or Loose Bricks
A chimney top that leans or has bricks you can wiggle is a safety problem, not a cosmetic one. Ice and wind work on it all winter. We look at it within days, and if it can't wait for spring we take the loose courses down before they come down on their own.

How Do You Know a Chimney Needs Repointing?
A chimney needs repointing when the mortar between bricks has sunk back about 1/4 inch or more, crumbles when you scrape it with a key, or has gaps you can see daylight through. The usual first sign from the ground is sand and grit in the gutter below the chimney.
- Mortar recessed or missing, especially on the top third of the chimney
- Spalling: brick faces flaking or popping off
- White salt stains (efflorescence), which mean water is moving through the brick
- Water stains on the ceiling or wallpaper beside the chimney
- A chimney top that leans or has loose bricks

Why Hard Mortar Ruins Old Binghamton Brick
We've seen this mistake more than any other in chimney masonry repair. Somebody repointed a 1920s chimney with hard, modern mortar, and ten years later the brick faces are popping off while the new joints look perfect. The National Park Service's guide on repointing says it plainly: new mortar must be softer than the brick. Mortar should be the part that wears, because it's cheap to replace and brick isn't.
Freeze-Thaw and the Top of the Chimney
Binghamton spends about 133 days a year below freezing and gets 83 inches of snow or more. The top of a chimney gets the worst of it, because it's wet from rain and snowmelt on all four sides. That's why most of our repointing starts at the roofline and works up, and why a sound chimney crown on top matters so much.
Should I Seal the Brick After Repointing?
Often, yes, with a breathable water repellent that lets moisture escape. Never a paint or plain sealer that traps it, because water stuck behind the face freezes and pops the brick. A good repellent keeps rain out of the new joints for years, and it goes on in an hour once the mortar has cured.
More on that is on our chimney waterproofing page. We do masonry work across the area, including Kirkwood.

Chimney Brick Repair Questions We Hear
Can You Match My Old Brick?
Usually close enough that you won't spot it from the yard. Binghamton chimneys from the 1910s to 1940s mostly used soft red common brick, and reclaimed brick of that era is still around. We bring two or three samples up to the chimney and pick in daylight.
Why Is My Chimney Brick Crumbling Inside the Attic?
Usually water coming down from the top, or acidic exhaust from an oil furnace getting through cracked flue tile. Fixing the brick without fixing the cause doesn't last. We'll check the crown, cap and liner and tell you which one it is.
Should I Take an Unused Chimney Down?
Sometimes it's the cheaper choice. An unused chimney that's falling apart above the roof can be taken down below the roofline and the roof patched over by a roofer. We'll price a repair and a take-down side by side so you can choose.
Questions we hear
Chimney Repointing FAQs
How much does chimney repointing cost in Binghamton?
Chimney repointing in Binghamton usually costs $800 to $1,800 for the top few feet above the roof and $1,800 to $3,500 for the whole exposed chimney. Replacing a few spalled bricks adds $400 to $900. A rebuild from the roofline up with a new crown runs $3,500 to $7,500.
What's the difference between repointing and tuckpointing?
Both replace worn mortar between bricks. Repointing is the general term; tuckpointing technically adds a thin contrasting line on top of the new joint. On chimneys around Binghamton, homeowners and masons use the two words for the same job: grinding out old mortar and packing in new.
How long does repointing last?
Good repointing with the right mortar lasts 25 to 40 years on a chimney, longer when the crown and cap keep the top dry. It lasts much less when water keeps getting in from a cracked crown, which is why we check the top of the chimney on every masonry job.
Can you repoint a chimney in winter?
Not well. Fresh mortar needs several days above about 40°F to cure, and frost in wet mortar ruins it. We do masonry from April through early November. Loose bricks that can't wait get taken down or secured in winter, and the full repair goes on the spring list.
Is a leaning chimney dangerous?
Yes, it can be. A leaning top usually means failed mortar joints, and ice, wind and snow loads can bring loose bricks down onto the roof or a walkway. Keep people away from that side of the house and have it checked within days. Most leans are fixed by relaying the top section.
