Professional Mold Removal - Done the Right Way, Step by Step
Each stage is performed by the independent remediation contractor the call reaches, following industry standards.
-
Step 1: Assessment
An assessor identifies the presence of mold, determines how far the growth extends, and locates the source of moisture.
-
Step 2: Containment
Protective barriers and negative air pressure are established to prevent spores from spreading into unaffected areas.
-
Step 3: Removal
Porous materials that cannot be safely cleaned are removed — including drywall past the moisture line, insulation, carpet pad, and damaged cabinet bases.
-
Step 4: Drying
Commercial dehumidifiers and air movers return the structure to a dry standard, with moisture readings taken from the material itself rather than the surface.
What drives moisture problems in Philadelphia
The Philadelphia area independent local pros cover for mold removal takes in Franklinville, Chopersville, and Hunting Park. The housing here is the oldest in this set, with a median construction year of 1949 and close to 88% of units built before 1990.
Housing stock
Of roughly 748,270 housing units, about 657,022 were finished in 1989 or earlier, which puts the median construction year at 1949. Brick rowhouses set the pattern, sharing party walls in continuous blocks, most with below-grade basements and flat or shallow-pitch roofs drained to internal leaders.
Climate and water risk
August is the wettest month here at 4.95 inches, part of an annual 50.69 inches in the 1991–2020 normals from PHILA FRANKLIN INST, 4.1 miles off. Summer thunderstorms deliver the heaviest totals, and on a block of rowhouses the water has nowhere lateral to go. A blocked internal leader or a failed parapet flashing sends it straight down inside the wall.
Common moisture and mold problems in Philadelphia
- Flat rowhouse roofs draining through internal leaders that back up when a single downspout blocks
- Continuous party walls carrying moisture between houses that have different owners and different repair histories
- Below-grade basements in blocks built long before damp-proofing was standard practice
- Parapet and cornice flashing failures that admit water at the top of a wall and reveal it two floors down

Frequently asked questions
What makes water damage in a rowhouse different from a detached home?
The walls are shared, so the problem is rarely contained to one address. A failed parapet or a blocked leader on one roof can wet the party wall serving three houses, and the neighbor who sees the stain may not be the neighbor who owns the defect. Scope has to consider the block, not just the room.
My basement has always been a little damp. Is that just how old houses are?
It is common in stock this age, but common is not the same as harmless. Persistent damp keeps joist ends, stair stringers and stored contents at a moisture level where growth establishes slowly and steadily. The question worth answering is whether it is groundwater, a drainage fault, or a plumbing leak, because the three have different fixes.
Where does water usually enter on a flat roof?
Almost always at a detail rather than in the field of the membrane: the parapet junction, a pipe penetration, or the drain itself. Ponding around a blocked drain is the most frequent single cause, because a flat roof that cannot shed standing water will eventually find the weakest seam.
