What a chimney is for

Two things it keeps out of your house

Smoke and gas go up. Rain and animals stay out. When a chimney stops doing those two jobs it rarely announces it, and the bill lands somewhere else in the house.

Before Living room ceiling opened up showing water damaged framing and soaked insulation
Before. Ceiling opened, framing wet, insulation soaked through.
After The same living room ceiling corner repaired and repainted
After. Same corner, closed back up and painted.

This started at the crown

Nobody calls about a cracked crown. They call about a stain on the ceiling, and by then the water has been running down the inside of the stack for a few seasons and the framing is wet.

That is the part worth understanding: almost everything expensive about a chimney started as something cheap that nobody looked at. An inspection is mostly about finding which cheap thing you have right now.

Most of our work is houses

Fireplaces, furnace flues, chases and stacks on ordinary homes across Southeast Michigan. It is the bulk of what we do and the part we are set up to turn around quickly.

Carbon monoxide in the rooms you sleep in

A cracked flue or a liner sized wrong lets combustion gas drift back into the house instead of going up and out. You cannot see it or smell it, which is exactly why it gets missed.

A chimney fire inside the wall

Creosote is fuel. Enough of it burns hot enough to crack tile and reach the framing around the flue. Sweeping takes the fuel out before it has a season to build up.

Water running into your ceilings

A failed crown, open mortar joints or a rusted cover lets rain straight down the stack. It shows up as stains, soft plaster and rotted decking, often a room away from the chimney.

A stack coming apart above the roof

Water gets into the joints, freezes, and pushes the brick faces off a little more each winter. Left long enough the stack leans and there is nothing to repoint.

Before and after

Same stack, joints cut out and repointed

Mortar is the part of any chimney that fails first, on a house or on a building. Once the joints wash out, every rain goes into the wall instead of running off it. This one sits on a flat commercial roof between two rooftop units, and repointing puts the barrier back either way.

Before Commercial brick chimney with eroded, washed out mortar joints
Before. Joints washed out, faces stained, water going straight in.
After The same chimney after tuckpointing, with clean full mortar joints
After. Joints cut back and repointed, colour matched to the brick.
Start to finish

A chase cover, the whole way through

A cover is a flat piece of metal sitting in weather for twenty years. When it goes, it takes the framing underneath with it if nobody catches it.

1 A rusted chase cover staining the siding below it
Rusted through. Standing water had been sitting on it, and the rust was running down the siding.
2 The chase with its cover removed and the top framing exposed
Cover off. Framing gets checked before anything new goes down. No point capping wet wood.
3 A new galvanized chase cover fitted to the chase
New cover. Fitted, sealed at the collar, with a drip edge so the water leaves the chase.
A hand resting on the edge of a freshly coated chase cover
Coating still wet. Every seam gets checked by hand.

How I run this

I take photos of everything I find up there and I show them to you before I put a number on anything. If something can wait a season, I will tell you it can wait. If it cannot, I will show you the picture and explain what happens if it does.

Most of this work is not glamorous. It is mortar, flashing, covers and liners. Done properly you stop thinking about your chimney entirely, which is the actual goal.
