Chimney Crown Repair & Replacement in Monsey & 30 miles around

What this service actually is

The crown sheds water away from the masonry. Most crowns around here were poured thin, flush to the brick, with no overhang and no expansion joint — so they crack within a decade and quietly funnel water straight into the chimney core for years before anyone notices.

What you get

• Cast crowns poured with proper slope, overhang and drip edge
• Flexible crown coating for crowns that are cracked but still structurally sound
• Expansion joint around the flue tile so heat does not re-crack the slab
• Stops the leak that is soaking your firebox, damper and interior walls
• Pairs naturally with cap installation and waterproofing for a complete top seal

How we do it

1. Assess the damage

Hairline cracks may only need a flexible membrane coating. A crumbling or sloped-wrong crown needs to come off and be recast.

2. Form and pour, or coat

We form a proper crown with a 2-inch overhang, slope away from the flue and a bond break around the tile — or coat a sound crown with an elastomeric membrane.

3. Seal the whole top

Crown, cap and a breathable masonry sealer together. Fixing one and skipping the others is how leaks come back.

Signs you need crown repair

If any of these sound familiar, it is worth a call. There is no charge to ask.

• Visible cracks across the concrete slab at the top of the chimney
• Chunks of concrete on the roof or in the gutters
• Water stains on the ceiling or wall near the chimney chase
• The crown looks flush with the brick with no overhang
• Mortar washing out of the joints just below the top

What it costs

Chimney Crown Repair & Replacement typically runs $450 – $1,600 for a standard single-family home in our service area, and takes about 1 day. The variables that move that number are roof access, flue height, how many flues share the stack, and condition.

“Raccoon in the chimney with babies. They removed them humanely, cleaned out about three feet of nesting junk, and capped it. No more wildlife, no more smell.”

Why homeowners pick Hero

We are a family company working out of Monsey, not a national franchise routing your call to a dispatcher three states away. That means the person who quotes your job is on the roof doing it, the price does not change halfway through, and if something is not right afterward we are twenty minutes away.

Every visit includes photo documentation. Every recommendation comes with an explanation of what happens if you wait, so you can make the call on your own timeline instead of ours.
