Caps & Crowns, Philadelphia

Your Local Chimney Cap and Crown Crew in Philadelphia, PA

The crown is the concrete or mortar slab at the very top of the chimney, and in Philadelphia it takes the worst of the weather. Water sits on it, freezes overnight and thaws by afternoon, and before long hairline cracks open and the brick below starts to soak. A cap keeps rain, leaves and animals out of the flue. We rebuild or seal crowns with a proper overhang, fit caps sized to each flue, and add multi-flue caps on older stacks that vent several flues at once.

Caps & Crowns for Philadelphia Homes

Philadelphia's January daily average is 33.7 degrees, and the temperature often climbs to 50 during thaws. The average window for freezing weather runs from about November 6 to April 2, which is a long season of freeze and thaw for a chimney crown.

Old Somerton, north of Byberry Road, has many larger houses from before 1900 mixed with newer mid-sized homes. The older houses often have stacks with more than one flue, and we cap every flue, including the ones no longer in use, so rain and animals stay out.

Caps and crowns are everyday work for us in Somerton, Fox Chase, Bustleton, Mayfair and Roxborough.

When to Call Us

  • No cap on top of the flue
  • Birds or animals in the chimney
  • Cracks across the crown
  • Rust stains on the firebox or damper
  • Water dripping into the fireplace

How the Job Goes

  1. Measure

    We measure the flue and crown so the cap fits and the crown sheds water.

  2. Repair or replace

    Small crown cracks get sealed; a failed crown gets replaced.

  3. Install the cap

    A cap sized to your flue, fastened to stay on in strong wind.

  4. Check the rest

    We look at the flashing and the top courses of brick while we are up there.

Caps & Crowns Questions in Philadelphia

Do unused flues in my chimney need a cap?
They do. A flue that no longer serves a fireplace still lets in rain and gives birds and squirrels a place to nest. We either cap it or seal it at the top, depending on whether you might use it again.
How long can a cracked chimney crown wait?
Not through another winter if you can help it. In Philadelphia's freeze and thaw cycle, a crack lets water into the brick and the damage grows each time it freezes, so the repair gets bigger the longer it waits.
Do I really need a chimney cap?
Yes. A cap is the simplest way to keep rain and animals out of the flue.
