Anthony was amazing from the start! He was incredibly personable, informative and professional. The pricing was fair with no hidden fees. The guys who came out to perform the work were professional and courteous. All in all C&J was so great to work with. Hopefully I never need mold removed again but if I do I would 100% call them!!
UBCTS in Perkasie
I used C and J recently to perform mold remediation at a home that I was selling near Independence Road. They were very professional, can on time and completed the work on budget. They did nice work and responded quickly so that the sale of the home could go through. Excellent service.

Remediation Services We Offer
Mold Moves Fast in Rowhomes. And Shared Walls Spread It.
Our Philadelphia calls follow the same pattern across neighborhoods: a homeowner in Fishtown, Kensington, or Northeast Philly notices a musty odor coming from the basement that has gotten progressively worse since the last sewer backup or heavy rain. In a city where summer humidity averages 68% and mold colonizes wet surfaces within 24 hours, the question is never whether mold is present. It is how far it has spread.
Too many Philadelphia homeowners called two contractors who gave inconsistent quotes and never returned to schedule the work, while the dark spots kept advancing toward the first floor.
Mold Moves Fast in Rowhomes
- Shared walls let mold travel to adjacent units undetected.
- Musty odors from basement sewer backups signal active growth.
- Allergy symptoms worsen each summer as humidity peaks again.
- Black bathroom staining signals growth behind the tile wall.
- Children and elderly residents face the highest ongoing risk.

Your Recovery Starts Here
Every mold job in Philadelphia starts with air quality testing and a certified inspection of the full structure. We build a remediation plan matched to the specific rowhome, basement, or commercial space.
Inspect the Structure and Test the Air Throughout
We begin every Philadelphia job with a certified mold inspection and air quality sampling. Rowhomes built from the late 1800s through the 1960s have original drainage, shared plumbing stacks, and wall cavities that trap moisture from sewer backups and rain infiltration. Our certified inspectors assess air quality throughout all affected floors before any remediation scope is proposed.Contain the Area and Remove All Active Mold
Once scope is confirmed, we establish containment to prevent spore spread to unaffected floors and adjacent units during remediation. We use HEPA-filtered extraction and eco-friendly, EPA-compliant treatments on all affected materials. In Philadelphia's attached rowhome stock, proper containment protects neighboring properties, and we document every step.Test the Air Again and Confirm the Property Is Clear
After remediation, we conduct post-remediation air quality sampling and provide written clearance results on every Philadelphia job. We do not consider the work done until the numbers confirm satisfactory air quality throughout the structure. Most of our Philadelphia clients say the clearance report is what finally gave them a written answer they could take to their insurance company and their building inspector.

Frequently Asked Questions
Does mold remediation in Philadelphia require permits?
Mold remediation work itself does not typically require a permit in Philadelphia. If remediation uncovers structural damage requiring significant rebuilding, or if work involves plumbing or electrical systems, a permit from the City of Philadelphia Department of Licenses and Inspections may apply. We advise on any applicable requirements before structural work begins.How long does mold remediation take in Philadelphia?
Most residential jobs in Philadelphia take two to five days from initial inspection through clearance testing. Rowhomes with original drainage, finished basements, and shared wall systems can take longer because moisture from sewer backups and rain infiltration travels through the full structure. We do not close any job until post-remediation air testing confirms satisfactory results.What affects the cost of mold remediation in Philadelphia?
The primary cost drivers are the size of the affected area, severity and type of mold growth, how long the moisture was present, and whether the property involves shared walls with adjacent units. Philadelphia rowhomes, particularly those in neighborhoods with combined sewer overflow risk, often see higher scope because moisture enters from multiple sources simultaneously. We provide a written scope document before beginning work.Do you handle residential and commercial mold in Philadelphia?
Yes. We serve single-family rowhomes, multi-family properties, and commercial buildings throughout Philadelphia's neighborhoods, from Fishtown and Kensington to Northeast Philly, South Philly, and Germantown. Commercial clients include property managers, office buildings, healthcare facilities, and institutional properties across the city.What warranty do you offer on mold remediation in Philadelphia?
We back every job with our satisfaction guarantee. If the remediation work does not resolve the mold issue or meet the agreed scope, we return and address it at no additional cost. All warranty terms are confirmed in writing before work begins.What should I do first if I find mold in Philadelphia?
Do not use fans near the affected area or disturb the mold. Document the visible growth with photos and note any musty odors, allergy symptoms, or sewer backup incidents that preceded the problem. Call us right away for a certified inspection. In Philadelphia's rowhomes, what appears as a small patch in one room is typically connected to a moisture source that runs through shared drainage and wall cavities across multiple levels.
