Chimney Repair Services
Leaks, cracks, crumbling mortar, or a damaged liner? Our CSIA-certified chimney sweeps find the problem, and our team repairs it, no matter who built your chimney.
Chimney damage almost always starts small. A hairline crack in the crown, a gap in the flashing, or a few loose mortar joints let water in a little at a time. Michigan winters do the rest, freezing that water inside the masonry and widening the damage every season. By the time you see a ceiling stain, crumbling brick, or pieces of tile in the firebox, the repair is bigger than it needed to be.
At Heat’n Sweep, chimney repair is open to every homeowner, whether we installed your fireplace or not. Every repair starts with an evaluation by a CSIA Certified Chimney Sweep®. We find where the damage starts, explain what it takes to fix it, and give you a clear quote before any work begins. From caps and crowns to liners and masonry, our team handles the repair from start to finish.
Fixing it early protects your home, your fireplace, and your budget.
Local Chimney Repair Services
Every part of your chimney has a job. Here's what we repair and how to tell when each one needs attention.
Chimney Caps
The cover on top of the flue that keeps out rain, snow, animals, and debris, and stops sparks from landing on the roof.
Signs: Missing or rusted cap, animals or nests in the chimney, water in the firebox.
The fix: A new stainless steel cap sized to your flue.
Chimney Crown
The concrete slab that seals the top of the chimney around the flue. It's the first line of defense against water.
Signs: Cracks, chips, or pieces of concrete on the roof.
The fix: Sealing small cracks, or rebuilding the crown with a proper overhang so water drips clear of the brick.
Chimney Flashing
The metal that seals the gap where the chimney meets your roof. It's the most common source of chimney leaks.
Signs: Water stains on the ceiling or walls near the chimney, lifted or rusted metal.
The fix: Resealing or replacing the flashing for a watertight joint.
Masonry & Tuckpointing
The brick and mortar that hold your chimney together. Mortar wears out faster than brick and needs to be replaced over time.
Signs: Crumbling mortar joints, flaking or spalling brick, white staining, or a leaning chimney.
The fix: Tuckpointing to replace worn mortar, brick replacement, waterproofing, or a partial rebuild.
Chimney Liners
The inside lining of the flue that contains heat and smoke and protects the house framing around it.
Signs: Cracked or missing tiles, pieces of tile in the firebox, or a new insert or stove going in.
The fix: A stainless steel liner sized to your fireplace, stove, or insert.
Dampers & Fireboxes
The damper seals the chimney when it's not in use, and the firebox holds the fire itself.
Signs: A damper that sticks or won't close, cold drafts, or cracked and loose firebrick.
The fix: Damper repair or a top-sealing damper, and firebox or firebrick repair.

We inspect the finished work, clean up, and show you what we did.
How Water Damages a Chimney
Water is the number one enemy of a masonry chimney, and Michigan's freeze and thaw cycles make it worse every winter. Here's how a small crack turns into a big repair.
Water gets in
Rain and melting snow soak into a cracked crown, worn mortar, or a gap in the flashing.
It freezes
Water expands about 9% as it freezes, pushing the brick and mortar apart from the inside.
Chimney breaks down
Brick faces flake off, mortar crumbles, liners crack, and water reaches your ceiling and walls.
The damage spreads
Each freeze and thaw widens the cracks, so more water gets in next time.
Signs Your Chimney Needs Repair
Chimney damage is easy to miss from the ground. Call us if you notice any of these:
- Water stains on ceilings or walls near the chimney

- Pieces of tile, brick, or concrete in the firebox or on the roof
- A rusted, damaged, or missing chimney cap
- A damper that sticks or won't close
- A chimney that leans or pulls away from the house
- Musty or smoky smells, especially after rain

Chimney Repair FAQs
Do you repair chimneys you didn't build?
Yes. Chimney repair is open to every homeowner, no matter who built your chimney or installed your fireplace, stove, or insert.
How do I know if my chimney is leaking?
Look for water stains on the ceiling or walls near the chimney, damp or musty smells after rain, water in the firebox, or white staining on the brick. The source is usually the crown, cap, or flashing.
Can a cracked chimney crown be repaired?
Small cracks can often be sealed. If the crown is crumbling, has wide cracks, or was built without a proper overhang, rebuilding it is the longer-lasting fix. We'll tell you which one yours needs.
Do I need a chimney liner?
Yes. NFPA 211 calls for chimneys to be lined. You'll need a new liner if the existing tiles are cracked or missing, or if you're adding an insert or stove that needs a liner sized to it.
Can chimney repairs be done in the winter?
Many can. Caps, dampers, and liners can usually be installed year-round. Mortar needs temperatures above freezing to cure properly, so some masonry and crown work waits for warmer days.
