Chimney Leak Repair From Your Local Crew in Philadelphia, PA

Water stains on the wall beside the chimney are one of the most common calls we get in Philadelphia. The cause can be flashing that pulled loose from a flat roof, a cracked crown, an open mortar joint or a missing cap, and sometimes it is condensation from a boiler flue rather than rain at all. We find out which before we quote. Then we reflash, repoint, rebuild the crown or cap the flue, using materials that suit your roof, whether it is modified bitumen on a row house or slate in the Northwest.

Open 24 hours, Sunday to Friday. Free written estimates.

Leak Repair for Philadelphia Homes

Philadelphia gets about 44 inches of rain a year, spread over eight to eleven days a month, and the wettest day on record brought 8.02 inches in July 2013. A small gap in the flashing that stays dry most weeks can let in a surprising amount of water on a day like that.

Many Mount Airy streets are lined with large three-story gray-stone houses, often with slate roofs. Where the chimney passes through slate, the flashing is hard to reach and easy to overlook, and that joint is where we start when a stone house leaks.

We fix chimney leaks in Mount Airy, Chestnut Hill, East Falls, Fishtown and Somerton.

When to Call Us

  • Stains on the ceiling or wall by the chimney

Leak Repair Questions in Philadelphia

Why is the wall next to my chimney damp even when it has not rained?
That often points to condensation inside the flue rather than a roof leak. Exhaust from a gas appliance carries water vapor, and in an unlined or oversized brick flue it cools and soaks into the masonry. A liner usually solves it.
Can you fix chimney flashing on a slate roof without breaking the slate?
Yes, with care. We lift and reset slates around the chimney, install new step and counter flashing, and work from roof ladders and hooks rather than walking on the slate.
Is it the roof or the chimney?
Often it is where they meet: the flashing. We check both before we say which.
