Chimneys in Upper St. Clair

Big chimneys, built in the suburban boom

Upper St. Clair grew mostly after the Second World War. Many homes are two-story colonials and other traditional styles from the 1950s on, often with a full-height brick chimney on an outside wall.

It's common to find two fireplaces plus a furnace or water-heater flue in the same stack. More flues means more to inspect, and a cap that has to cover all of them.

A two-story exterior chimney takes the full force of wind, rain and freeze-thaw, and the first thing to fail is usually the crown.

Common here

Mortar wash

A thin layer of mortar troweled over the top bricks. It's flat with no overhang, so water runs into the brick. It cracks, and the damage spreads down the stack.

The fix

Formed crown

A proper slab that slopes away from the flues and overhangs the brick, so water drips clear. About caps and crowns.

We have two fireplaces in one chimney. Do both need sweeping?

Each flue is its own passage, so each one gets cleaned and inspected on its own. If one fireplace hardly gets used, it may need less cleaning, but it still needs an inspection for nests, debris and liner damage. We'll note every flue separately in your photo report.

Can you inspect the chimney before we close on a house in Upper St. Clair?

Yes. NFPA 211 calls for a Level 2 inspection at a property sale, which includes a camera look inside every flue. We schedule around closing dates and send a written report your agent can share. More on our real estate page.

Is a cracked crown worth fixing, or can it wait?

Small hairline cracks can sometimes be sealed. Wide cracks, missing chunks or a flat mortar wash usually mean the crown should be rebuilt. Waiting lets water into the brick each winter, which turns a crown job into masonry repair. We'll show you photos and give you a written price for each option.

We switched our fireplace to gas logs. Does it still need service?

Yes. Gas logs still need a yearly inspection of the flue, damper and logs. We also check that the damper is set correctly for vented gas logs, since a closed damper with gas logs burning is a carbon monoxide hazard.

How much does a chimney sweep cost in Upper St. Clair?

It depends on the service, the number of flues, the type of fireplace or appliance, and how easy the chimney is to reach. You get the price upfront and in writing before any work begins, and if we find something that needs repair, the estimate is free.
