Chimney Crown Repair Cost in Lexington, KY

Crown repair is two jobs that share a name. A crown that is whole and bonded to the brick, with hairline cracks, is cleaned, filled and given a flexible crown coat. A crown split clean through, crumbling at the edge or lifting from the top course is broken off, formed and poured new. From the yard the two cracks look identical and the jobs differ by an order of magnitude, which is why no crown range is printed here. The crown should be read from the roof, with the figure in writing.

Coat or pour

Which repair it is. A crown coat is the maintenance end of the trade; a formed pour, with the old crown broken off and brought down, the other end.

Footprint and flue count

A new crown is sized to the stack’s footprint and the flues it surrounds. Versailles’ estate stacks, several flues under one crown, are the large case.

What is under it

Once the old crown is off, the top courses are checked. Courses that have lost their bond turn a crown job into a partial rebuild, from $4,000, which you should see in photos before it goes ahead.

The flue tiles

Tiles found cracked once the crown comes off turn it into a liner conversation; a stainless liner runs $1,500–$7,000 here.

The cap

A cap on a cracked crown is a lid over a leak, so the two are quoted together, the cap’s flue count and dimensions on the same scope.

Height and access

A crown a few courses above a low roof is formed from a ladder; a tall stack on a steep pitch needs staging, named on the scope.

The crown is the top rung of the ladder every chimney repair here climbs. Water through the crack goes into the joints; a Kentucky winter freezes it dozens of times; the joints go to sand, which is repointing at $500–$2,500. Left longer, the wet joints spall the brick, and a spalled, hollow-jointed stack racks and leans, a rebuild from $4,000 to $15,000. Whatever a crown repair comes to, it is the cheapest rung there is.

Every rebuild ends with a new crown, because the old one comes off with the courses beneath it, so on a rebuilt stack the crown is scoped with the rebuild; the seven rebuild drivers include it. Short of a rebuild, the crown’s row sits with joints, caps and spalled brick on what the other repairs run here.

Expect a roof visit, and ask for the crown to be photographed from above and at its edge, the cap read with it, and a camera down the flue where the tiles are in question. Then expect a written scope: coat or pour, cap, staging, a slot in the March-to-November season, and a firm figure. If a coat will genuinely hold, the scope should say so and carry the smaller number; how each repair is done is on the crown repair page.
