Crack sealing
Hairline cracks are sealed with a flexible crown coating before water and frost can widen them.

Chimney Crown Repair Tamaqua, PA
A Tamaqua chimney technician can repair the crown, the concrete slab that seals the top of the chimney around the flue, with a design that sheds water past the masonry. Call (272) 291-2023 to reach a local chimney sweep.
A chimney crown covers the top of the brick and slopes away from the flue so water runs off instead of soaking in. It takes more weather than any other part of the chimney, so it is often the first thing to crack. Once it cracks, water runs straight into the brick and mortar below, and every freeze widens the crack.
A crown is not the same as a chimney cap, though the words are often mixed up. The crown is the masonry slab, while the cap is the metal cover with a mesh screen that sits over the flue opening. A new cap will not stop water from soaking in through a cracked crown.
Crowns often fail sooner than they should for a few common reasons. A common shortcut is a thin layer of mortar troweled over the top, with no overhang to throw water clear and nothing to let the flue tile expand. Mortar is not meant for that job, and a flue tile that heats and expands will crack a crown that is cast tight against it.
If the problem goes deeper than it first looked, a Tamaqua chimney sweep may also recommend chimney cap installation or chimney leak repair.

How chimney crown repair works
The right fix depends on whether the crown is basically sound with surface cracks or failing all the way through.
Assess the cracks
From the roof, the crown is examined for cracks, crumbling, poor slope and missing overhang. The flue tile, cap and upper brick are checked at the same time, since crown damage often spreads to them.
Prep the crown
The crown is scrubbed of dirt, growth and loose pieces so repair material can grip. Good prep decides how long the repair lasts.
Seal minor cracks
For minor cracking, a brushable crown repair coating seals the cracks and stretches with the concrete as it moves. It is the least invasive fix when the crown is still intact.
Recast the top
A failing crown is chipped off and replaced with a properly built concrete crown. A proper replacement slopes away from the flue and extends past the brick with a drip edge underneath.
Expansion joint
The crown is separated from the flue tile by an expansion joint sealed with flexible material. It is one of the most overlooked parts of a crown.
Protect the work
A cap goes back on once the new crown is ready. Any spalled brick at the top can be repaired at the same time.
What is included
Types of crown repair
Bond breaks
The flue tile is separated from the crown which keeps the new crown from cracking early.
Crown replacement
A failed crown is replaced with a properly built concrete crown with a slope, overhang and drip edge.
Upper brick repair
Spalled bricks and worn joints near the top are repaired along with the crown so the new crown sits on sound masonry.
Overhangs
New crowns are built to overhang the brick with a groove underneath which keeps runoff from soaking the masonry.

Chimney Crown Replacement Tamaqua, PA
When a crown has deep cracks, loose chunks or no overhang at all, replacing it is more reliable than sealing it. Replacement starts with removing the old crown and inspecting the masonry underneath. Some crowns are cast in place on the chimney, and others use a precast crown set on a bed of mortar, both with an overhang and a gap around the flue.
For Tamaqua homeowners, timing matters with crown replacement. Concrete needs to cure without freezing, so most crown replacements are done from spring into fall. In the meantime, a temporary cover can keep the worst of the water out. Make sure the plan includes a drip edge and a flexible joint around the flue, not just new concrete.

How the weather here affects chimneys around Tamaqua
Winters here are long and cold, and the heating season usually runs from October well into April. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Tamaqua is usually booked in the fall, before the first cold night.

Chimney Crown Repair FAQ
What is the difference between a chimney crown and a chimney cap?
Think of the crown as the roof of the chimney and the cap as the lid on the flue. They protect different parts of the chimney. A damaged crown needs its own repair.
Is a cracked chimney crown a big deal?
A cracked crown is worth fixing quickly, even if the crack looks small. The water it lets in damages the brick, the flue and the framing around the chimney. Caught early, a crown seal is simple, but left alone, the damage can spread down the chimney.
When does a chimney crown need replacing?
How long a crown lasts depends mostly on how it was built. Crowns made from mortar mix, with no overhang or no gap around the flue tile, fail much sooner. Yearly inspections, as NFPA 211 recommends, are the best way to keep an eye on it.
What causes chimney crowns to crack?
Crowns crack from water freezing in small cracks, from being built thin out of mortar, and from the flue tile expanding against them. A crown cast tight against the flue tile will crack when the tile heats and expands. Water and frost then finish the job.
Do I need a new crown if mine is cracked?
How far the cracking goes decides it. Minor surface cracks are usually sealed with an elastomeric crown sealer. If the crown is cracked through, crumbling or missing pieces, replacement is the better option.
