Chimney masonry repair in Pittsburgh
Repointing, spalled brick replacement and chimney rebuilds for Pittsburgh's brick chimneys. We fix what's actually failing, match the mortar to your brick, and give you a written estimate with photos before any work starts.
Pittsburgh winters work on your chimney every year
Brick and mortar are porous. Pittsburgh winters swing across the freezing point over and over, so water in the masonry freezes, expands and thaws many times in a single season.
The part above the roofline takes the worst of it, because it's exposed on all four sides. A chimney can look fine from the yard and still have open joints at the top. Our inspection checks the whole stack, with photos of what we find.
The freeze-thaw cycle
- 1. Water gets in
- Rain soaks into the brick and through cracked joints.
- 2. It freezes
- Ice expands and widens the cracks. Mortar turns sandy and falls out.
- 3. Brick spalls
- The face of the brick pops off, letting in more water, so damage speeds up.
- The fix
- Grind out to sound mortar, refill with the right mix, and replace failed brick.
The right fix for the damage you have
Most chimneys don't need a full rebuild. We'll show you what's failing and price the smallest repair that will actually last.
Repointing
Failed mortar is ground out to sound material and the joints are refilled and tooled. The most common chimney repair, and the one that prevents most of the others.
Spalled brick replacement
Individual bricks with blown faces are cut out and replaced with sound brick as close to your originals as we can source.
Partial rebuild
When the damage is concentrated above the roofline, we take the chimney down to solid masonry and rebuild from there with a new crown.
Full rebuild
For chimneys that lean, have widespread loose brick or structural cracks. Rare, and we'll show you clearly why it's needed.
Crown repair
The concrete slab on top sheds water away from the brick. Cracked crowns are sealed or rebuilt. Caps & crowns
Waterproofing
After repairs, a breathable water repellent slows down the next round of freeze-thaw damage. Leaks & waterproofing
What to look for from the ground
- Mortar joints that are recessed, sandy or missing
- Brick faces flaking, popping off or crumbling
- White, chalky staining on the brick (efflorescence), a sign water is moving through it
- Pieces of brick or mortar on the roof, in the gutters or on the ground
- The chimney leaning, or cracks running through several courses of brick
- Damp patches or stains on walls and ceilings beside the chimney
How we do masonry work
- Mortar matched to the brick. Older, softer brick needs a softer mortar. Mortar that's harder than the brick forces the damage into the brick itself.
- Color matched as closely as we can. New mortar is usually a little brighter at first and weathers in over time.
- Ground out to sound mortar. Not a skim coat smeared over the surface, which tends to fall off in a winter or two.
- Roof, siding and landscaping protected. Tarps down and debris hauled away.
- Before-and-after photos. Including the parts you can't see from the ground.
- Free written estimate. Itemized, with options where there is a real choice to make.
Tuckpointing or repointing?
Strictly speaking, repointing means replacing failed mortar, and tuckpointing is a decorative finish that adds a thin contrasting line to the joint. In Pittsburgh most people say tuckpointing for both, and that's fine. When you call about tuckpointing, we know you mean your joints are failing.
Either way, the work is the same: cut out the bad mortar, refill with the right mix, and tool the joint so it sheds water. Masonry needs to cure above freezing, so in the coldest weeks we schedule mortar work for milder days or take temporary steps to keep water out until then.
| What we find | Usual repair |
|---|---|
| Joints worn or open, brick still sound | Repointing |
| A handful of spalled bricks | Brick replacement plus repointing |
| Loose brick and open joints above the roofline | Partial rebuild and new crown |
| Lean, structural cracks or widespread failure | Full rebuild |
| Cracked crown, brick otherwise fine | Crown repair or rebuild |
From first look to finished joint

Protect the repair
Caps & Crowns
A sound crown and a good cap keep rain off the top of the brick, where damage starts.
Leaks & Waterproofing
Flashing repair and breathable water repellent to keep water out of the masonry.
