Client Testimonials
Hear from your Lansdale neighbors
I have used C & J for several Citrashield projects in the Bucks County area. Always fair, on time and complete the tasks given. Citrashield is proud to have C & J as an approved applicator.
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!!
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 Thrives in Older Rentals. And Tenants Feel It First.

Many of our Lansdale calls come from property managers or homeowners who received a complaint about a persistent musty smell in a unit near Main Street or along the Stony Creek corridor. In a borough where 44.7% of units are renter-occupied, moisture problems in older row homes often go unaddressed until the visible dark spots have spread beyond one room.
Too many Lansdale property owners received a quote from a contractor who never followed up, while the mold continued spreading to the unit next door.
Mold Thrives in Older Rentals
- Dark spots in shared walls spread from unit to adjacent unit.
- Musty odors in basements rise to occupied floors above.
- Tenant allergy complaints often signal active mold growth.
- Deferred moisture in row homes compounds with every rain.
- Children and elderly tenants face the highest health risk.

Your Recovery Starts Here
Every mold job in Lansdale starts with identifying the moisture source and testing the air in all affected units. We build a plan that resolves the problem across the full scope of the property.
Inspect the Property and Test Air Quality
We begin every Lansdale job with a certified mold inspection and air quality sampling. Older row homes and attached units in this borough were built in the railroad era and early post-war period, with shared drainage and original plumbing systems that fail silently and introduce moisture behind walls. Our certified inspectors document the full scope before any remediation begins.Contain the Affected Areas and Remove All Active Mold
Once scope is confirmed, we establish containment to prevent spore spread to unaffected units during remediation. We use HEPA-filtered extraction and eco-friendly, EPA-compliant treatments on all affected materials. Property managers in Lansdale consistently tell us that our thorough documentation is what they need to satisfy both their insurance carriers and their tenants.Test the Air Again and Confirm Written Clearance
After remediation, we conduct post-remediation air quality sampling and provide written clearance results. We do not consider a Lansdale job complete until the air quality numbers confirm satisfactory conditions throughout all affected areas. The clearance report is what most of our Lansdale landlords use to demonstrate the work was completed to standard.

Frequently Asked Questions
Does mold remediation in Lansdale require permits?
Mold remediation work itself does not typically require a permit in Lansdale Borough. If remediation uncovers structural damage requiring significant rebuilding, or if work involves plumbing or electrical systems, a permit from Lansdale Borough may apply. We advise on any requirements before structural work begins.How long does mold remediation take in Lansdale?
Most residential and rental unit jobs in Lansdale take two to five days from initial inspection through clearance testing. Older row homes and railroad-era attached housing can take longer because shared wall systems and original drainage hold moisture differently than newer single-family construction. We do not close any job until post-remediation air sampling confirms satisfactory results.What affects the cost of mold remediation in Lansdale?
The primary cost factors are the size of the affected area, severity and type of mold growth, how long the moisture source was active, and whether the property is a single unit or part of a shared building. In Lansdale's rental stock, multi-unit row homes with shared plumbing or drainage often require a broader scope than single-family properties. We provide a written scope document before beginning work.Do you handle residential and commercial mold in Lansdale?
Yes. We serve owner-occupied homes, rental units, and multi-family properties throughout Lansdale Borough. We also work with commercial property managers and building owners along Main Street, Broad Street, and the Route 309 corridor. Our team handles everything from a single-unit remediation to a multi-unit apartment building response.What warranty do you offer on mold remediation in Lansdale?
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 Lansdale?
If you are a homeowner, do not disturb the mold or run fans near the affected area. If you are a property manager, contact us before notifying tenants to allow us to assess the full scope. Document what is visible, note any musty odors or tenant complaints, and call us right away for a certified inspection. In Lansdale's older row homes, visible surface mold is frequently connected to a moisture source that spans multiple units through shared wall systems.
