Chimney crown repair in the Twin Cities
The short answer: MockingBird Chimney repairs and replaces chimney crowns across the Minneapolis–St. Paul metro. The crown is the concrete or mortar slab on top of the chimney, and it takes the worst of Minnesota's freeze-thaw punishment — water gets into hairline cracks, freezes, and widens them every winter. Small cracks can often be sealed with a flexible waterproof coating. Once a crown has failed more seriously, it needs to be fully re-poured. Because the right fix depends on how far the damage has progressed, estimates are free and given after we look at the actual crown, never guessed over the phone. This is also one of the most common sources of a chimney leak that seems to come from nowhere.
What's Included

What crown repair actually involves.

Crack assessment

How far the damage has progressed determines whether sealing or a full re-pour is the right fix.

Crack sealing

Flexible waterproof sealant for hairline cracks caught before they get worse.

Crown resurfacing

A new surface layer applied over a crown that's still structurally sound underneath.

Full crown re-pour

Complete replacement when the existing crown has already failed.

Proper overhang & drip edge

Rebuilt to shed water away from the masonry below, not straight onto it.

Final waterproofing

A breathable sealant applied once the repair is complete for lasting protection.

Signs You Need One

How a failing crown usually shows up.

01

Visible cracks across the crown

Even hairline cracks are worth sealing before another Minnesota winter widens them.

02

Water stains inside near the chimney

A failed crown is one of the most common sources of a leak that seems to come from nowhere.

03

Crumbling or spalling concrete on top

Visible pieces breaking away from the surface, usually most obvious right after winter.

04

Standing water after rain

A properly sloped crown should shed water — pooling means the slope or surface has failed.

05

An inspection flagged the crown

One of the most common specific findings on a Level 1 or Level 2 inspection.

Pricing

Why crown repair varies so much.

Sealing a few cracks and fully re-pouring a crown are very different jobs at very different prices.

Extent of cracking

A few hairline cracks versus widespread failure across the whole crown.

Sealing vs. full re-pour

A complete re-pour costs more than a sealant application on a sound crown.

Larger chimneys simply have more surface area to seal or rebuild.

Access & height

Staging is sometimes needed for taller or hard-to-reach chimneys.

Common Questions

Straight answers.

It depends on whether the crown needs sealing or a full re-pour, plus its size and how accessible it is. We give a free on-site estimate with a written quote before any work begins.

The crown is the flat concrete or mortar slab that covers the top of the entire chimney structure. The cap is the smaller metal cover that sits directly over the flue opening, usually with mesh to keep animals out. Both are common leak sources, but they're different components.

Often, yes, if it's caught early. Hairline cracks can typically be sealed with a flexible waterproof coating. Once cracking is widespread or the crown has started to break apart, a full re-pour becomes the right fix.

Sealing typically takes a few hours. A full re-pour usually takes a day, plus curing time before the final waterproofing is applied.

Yes, and it's one of the most common sources of a leak that otherwise seems to come from nowhere. Water enters through crown cracks and travels down inside the chimney structure before showing up as a stain somewhere else entirely.

A properly built crown with correct overhang and drip edge typically lasts 20 years or more, even through Minnesota winters, as long as it's sealed and monitored during routine inspections.
