Mount Airy lies between Germantown and Chestnut Hill along Germantown Avenue, with the Wissahickon gorge on its western edge and Stenton Avenue on its eastern. The housing is 1900s through 1930s stone and brick twins and rowhouses built from local Wissahickon schist, with slate roofs, deep porches, and fieldstone basements, plus larger stone singles on the streets closest to the park.
Owners in Mount Airy reach an independent local mold provider through the phone number on this site. That provider walks the house with a meter and says what it needs. Our part is the call.
Schist and slate are the mold story here. A schist foundation breathes ground moisture through every joint, and a basement finished in the 1970s with paneling and carpet holds that moisture against the wall through a humid summer. Slate roofs past ninety years lose slates one at a time, and one missing slate over an attic with a buried bathroom fan duct makes a dark north slope within a few winters. The combined sewer backs up on the low blocks toward Germantown in a hard storm.
A speckled roof deck across one slope of a twin's attic is attic mold remediation. A finished basement wall over fieldstone that reads wet is mold removal. Putting the basement back with a drainage gap and a board that tolerates a damp wall is mold damage repair.
Mt. Airy CDC works on housing and the Germantown Avenue commercial corridor from its office on the avenue, and its housing counselors are the people many owners here call first about a repair they cannot pay for all at once.
Call (215) 600-0376 and tell us what you see. We put you through to a local mold provider serving Mount Airy.
Growth on plaster or drywall after a party-wall leak, a stone-foundation seep, or a radiator pipe: room sealed, wet material cut to the meter line, framing HEPA-cleaned and dried.
A dark patch on a basement wall or bathroom ceiling handled by how far the water traveled, not its color: containment, porous material out, hard surfaces cleaned, source fixed.
A sewer backup that filled the basement or a flat-roof leak that ran down three floors, mapped floor by floor and cleared in zones as one project.
Coil, drain pan, and condensate line cleaned or replaced when a basement or closet air handler sweats through a humid Philadelphia summer.
Growth behind a vanity, under a tile shower, or on a ceiling with no exhaust fan in a rowhouse second-floor bath, removed with the leak fixed first.
Growth on rafters and sheathing under a flat roof or a twin's slate roof, cleaned and treated once the roofing or the ventilation is corrected.
A musty smell in a rowhouse that looks fine, traced to a wet stone wall, a damp joist end, or the dirt under an old cellar floor, then removed and treated.
Plaster, drywall, baseboard, and subfloor put back after removal, once the basement reads dry and the roof, pipe, or drain that caused it is repaired.
