Visible Cracks or Missing Chunks
Cracks across the concrete slab on top of the chimney, or pieces that have broken away, mean water now has a direct path into the masonry and down toward the flue.

Warning Signs
Three Signs a Crown Is Failing
Crown damage is invisible from the ground and expensive once it reaches the inside of the house. These are the signs worth acting on now.
White Staining or Spalling Brick
Efflorescence — white mineral staining — and brick faces flaking off below the crown both say the same thing: water is moving through the chimney from the top.
No Slope and No Overhang
A crown poured flat and flush with the brick sheds water down the chimney face instead of away from it. It is a construction shortcut, and it always shows up as damage later.

What We Do
Repairs That Shed Water Instead of Hiding It
Full Crown Rebuild
The failed crown is removed and replaced with a reinforced, properly sloped concrete crown that extends past the brick with a drip edge — built to last decades, not seasons.
Crown Sealing & Coating
Where the crown is structurally sound but showing hairline cracks, a flexible waterproof coating bridges the cracks and buys many years without an unnecessary rebuild.
Expansion Joint at the Flue
Concrete and clay flue tile expand at different rates. We install flexible joint material at that seam so the crown does not crack open where it meets the flue.
Masonry Waterproofing
Once water has been soaking the brick, we apply a breathable masonry sealer that keeps water out while letting trapped moisture escape — never a film-forming paint that traps it.
How It Works
From Cracked Crown to Sealed Chimney
1. Tell Us What You See
Cracks on top, white staining, flaking brick, a leak near the chimney — describe it and we book a roof-level look.
2. Inspect the Crown
We check the crown, the slope, the overhang, the flue joint and the brick underneath, and photograph all of it so you see what we see.
3. Seal or Rebuild — Honestly
Sound crown with hairline cracks gets sealed. Failed crown gets rebuilt. You get the recommendation and the written price before any work.
4. Do the Work Right
Reinforced concrete, correct slope, real overhang with a drip edge, flexible joint at the flue. The details are what make a crown last.
5. Photo Confirmation
Finished photos from the roof so you can see exactly what was built, without climbing a ladder yourself.
Sealing vs. Rebuilding — The Honest Version
Not every cracked crown needs to be torn off. A structurally sound crown with hairline cracks can be coated with a flexible waterproof membrane that bridges the cracks and lasts years. That is a real repair, not a shortcut — and it costs a fraction of a rebuild.
What cannot be coated: a crown with wide structural cracks, missing sections, no slope or no overhang. Sealing those hides the problem for one season and the water keeps coming. We tell you which one you have and show you the photos that prove it.

“Water stains on the ceiling after every downpour. It was the flashing and a cracked crown. They fixed both, waterproofed the brick, and it's been dry through the worst of the season.”

“Old cap blew off in a storm. New stainless one is solid, and they checked the crown and mortar while up there. No upselling, just told me what was fine and what wasn't.”

(312) 952-4814The crown is the concrete slab across the top of a masonry chimney that seals the space between the flue tile and the outer brick. It is the chimney's roof — its job is to shed rainwater away from the masonry.
It depends on the size of the chimney and whether the crown can be sealed, partially repaired or needs a full rebuild. We inspect from the roof and give one written price before work begins — never a phone guess.
Hairline cracks in an otherwise sound crown can be sealed with a flexible crown coating, and that is a legitimate long-term repair. Wide cracks, missing sections, or a crown with no slope or overhang need rebuilding.
Water enters the chimney at the top and works down: saturated brick, spalling masonry, a rusted damper, a damaged liner and eventually ceiling stains inside the house. Crown repair is far cheaper than the damage that follows it.
Most crown rebuilds are a one-day job, plus curing time before the chimney should be exposed to heavy rain. We schedule around the weather forecast.
The crown is the concrete slab across the whole top of the chimney. The cap is the metal cover over the flue opening itself. Most chimneys need both, and a failure in either lets water in.
