Chimney Flashing Repair in Bunker Hill, Waterbury from $300. An estimated $300 to $1,800 – the commonest source of a leak on an older Waterbury house. Free inspection and a written quote.
On Bunker Hill capes the chimney often rises through a finished upper story, so a flashing leak shows as damp on a bedroom wall rather than in an attic. That is easy to mistake for condensation, and worth ruling in properly.
A chimney leaks from one of four places: the step flashing up the sides, the apron at the front, the cricket or back pan behind, or the counter-flashing let into the mortar. On older stacks the mortar is usually the weak link. Once the joints erode the counter-flashing pulls loose, water runs down behind the metal, and caulk on the surface never reaches it.
Chimney flashing repair is estimated at $300 to $1,800 in most cases. It is the commonest single source of a recurring leak on a pitched roof, and Waterbury's pre-war houses have a great many old masonry stacks. The most predictable pricing on this site: bigger lots, room to stage, and simpler roof shapes. A cape with rooms in the roof adds eaves and ventilation work that an open attic would not.
One failed detail on sound brickwork – counter-flashing pulled out of a joint, or an apron lifted at a corner.
Eroded mortar that has to be raked and repointed before new metal can bed into it, and a missing cricket on a wide stack.
Fresh caulk on weathered metal. New step flashing is bright against an old stack; reused flashing with a bead run round it looks tidy only from the street.
Capes with rooms in the roof are the thing to establish first. A finished upper story changes the ventilation and makes the eaves harder to detail, and the eaves is exactly where Connecticut's ice barrier rule does its work.
On a cape, find out whether anyone sleeps up there before anything else gets decided.
All four details, and the mortar behind them.
Step flashing, apron, cricket and counter-flashing are each checked, because the visible one is rarely the only one failing.
Eroded joints are raked out and repointed, so the counter-flashing has sound mortar to sit in.
Behind any chimney wider than 30 inches a cricket is built, so drifting snow and meltwater go around the stack instead of under the shingles.
The most straightforward replacements in Waterbury are on Bunker Hill: bigger lots, room for a dumpster in the drive, and plainer roofs on colonials and later ranches.
On Bunker Hill capes the classic repair is at the eaves of a finished upper story, where warm rooms melt snow that refreezes at the cold overhang.
Bunker Hill's emergencies are mostly ice dams on capes and storm damage on bigger, open lots where trees and wind reach the roof.
On Bunker Hill the typical flat roof is a garage, a breezeway or a rear addition on a cape or ranch, draining onto a pitched roof or a driveway.
Slate is uncommon on Bunker Hill's colonials, capes and ranches, so a slate repair here is usually on one of the older houses from the trolley-era subdivisions.
On Bunker Hill the inspection establishes whether the roof space is finished rooms or open attic.

Answered before anyone books a visit.
Only as a stopgap. Caulk over old metal holds for a season or two, and once the mortar behind the counter-flashing has eroded, water runs behind the metal where no surface sealant reaches.
We rake and repoint the joints the flashing depends on. Where the brickwork itself is failing we say so plainly, because new flashing on a spent chimney does not last.
If it is wider than 30 inches across the slope, the code asks for one. A cricket sheds water and snow around the back of the stack; without it, drifting snow sits against the brickwork and the meltwater finds its way under the shingles.
