Key Takeaways
- Many Philadelphia rowhomes built or renovated before the 1980s contain asbestos in pipe insulation, boiler coverings, vinyl floor tiles, linoleum adhesive, ceiling tiles, plaster, joint compound, and roofing materials.
- Asbestos itself isn’t dangerous until disturbed, cutting, sanding, drilling, or breaking apart these materials during renovation releases microscopic fibers into the air.
- Illnesses from asbestos exposure, including mesothelioma, lung cancer, and asbestosis, often don’t appear for 20 to 40 years after exposure.
- Both professional contractors and DIY renovators face exposure risk, and because rowhomes share walls, dust can travel and put neighbors at risk too.
- Asbestos testing before any renovation project is one of the most important safety steps homeowners can take.
- Improper removal or disposal isn’t just a health risk, it can also create legal and financial consequences.
Philadelphia rowhomes tell the story of the city itself. Block after block, these homes reflect generations of families, craftsmanship from another era, and neighborhoods built long before modern building standards existed. For many homeowners and renovators, restoring or updating a rowhome is a labor of love. But behind the brick facades and plaster walls, many of these homes contain a hidden risk that too often goes unnoticed: asbestos.
A Product of Its Time
Asbestos was once considered a miracle material. For decades throughout the 20th century, it was used in homes for insulation, fireproofing, and durability. In Philadelphia, where a large portion of rowhomes were built or renovated before the 1980s, asbestos-containing materials were commonly installed without any understanding of the long-term health consequences.
Because asbestos does not look dangerous, many people assume it is no longer an issue. In reality, it remains present in countless homes across the city, quietly aging along with the buildings themselves.
Where Asbestos May Be Hiding
In older rowhomes, asbestos is most often found in places people don’t think twice about during a renovation. Pipe insulation in basements, boiler coverings, vinyl floor tiles, old linoleum adhesives, ceiling tiles, plaster, joint compound, roofing materials, and cement products may all contain asbestos. Even small projects like replacing flooring, opening walls, or upgrading plumbing can disturb materials that have been undisturbed for decades.
The danger isn’t always obvious. Asbestos fibers are microscopic, invisible to the naked eye, and easily released into the air when materials are cut, sanded, drilled, or broken apart.
Renovation Turns a Hidden Hazard into a Real Risk
Asbestos becomes hazardous when it is disturbed. Renovation work, whether a full gut rehab or a weekend DIY project can release fibers that linger in the air and settle on clothing, tools, and furniture. Once inhaled, asbestos fibers can lodge deep in the lungs, where the body cannot easily remove them.
Health effects from asbestos exposure often do not appear for decades. Illnesses such as lung cancer, asbestosis, and mesothelioma can develop 20, 30, or even 40 years after exposure. This long latency period is one of the reasons asbestoses remains such a dangerous and underestimated risk today.
Contractors, DIYers, and Families at Risk
Professional contractors, plumbers, electricians, and renovation crews face repeated exposure risks when working in older homes. Many began their careers long after asbestos regulations were put in place and may not expect to encounter it in residential settings.
Homeowners and do-it-yourself renovators are also vulnerable. Without training or protective equipment, people may unknowingly expose themselves and their families. Dust can travel through shared walls in attached rowhomes, putting neighbors at risk as well.
Why Testing and Compliance Matter
Before beginning renovation work in an older Philadelphia row home, asbestos testing is one of the most important safety steps that can be taken. Local, state, and federal regulations outline how asbestos must be handled and removed when it is present. These rules exist not only to protect workers, but also to prevent contamination of homes and surrounding communities.
Improper removal or disposal can create lasting health hazards and may result in serious legal and financial consequences. More importantly, it can expose people who never chose to take that risk in the first place.
A Continuing Issue in a Historic City
Philadelphia’s housing stock is among the oldest in the nation, and asbestos exposure remains a real public health concern. As revitalization and renovation continue across the city, awareness and education are critical. Knowing what questions to ask before starting a project can make the difference between a safe renovation and one with long-term consequences.

Frequently Asked Questions
Why do so many Philadelphia rowhomes contain asbestos?
A large portion of Philadelphia’s rowhomes were built or renovated before the 1980s, when asbestos was widely used for insulation, fireproofing, and durability without any understanding of the long-term health risks.
Where in a rowhome is asbestos most commonly found?
Common locations include pipe insulation in basements, boiler coverings, vinyl floor tiles, old linoleum adhesive, ceiling tiles, plaster, joint compound, roofing materials, and cement products.
Is asbestos dangerous if it’s just sitting undisturbed in my walls or floors?
Asbestos becomes hazardous mainly when it’s disturbed. Renovation work, whether a full gut rehab or a small DIY project, can release fibers that linger in the air and settle on clothing, tools, and furniture.
Who is at risk during a rowhome renovation?
Professional contractors, plumbers, electricians, and renovation crews face repeated exposure, but homeowners and DIY renovators without training or protective equipment are also vulnerable. Because rowhomes share walls, dust can even travel to neighboring units.
Why does asbestos testing matter before starting a renovation?
Testing is one of the most important safety steps before renovation work begins. Local, state, and federal regulations govern how asbestos must be handled and removed, and improper removal or disposal can create lasting health hazards along with legal and financial consequences.
What should I do if I think I’ve been exposed to asbestos during a renovation?
If you’re concerned about past exposure or have been diagnosed with an asbestos-related illness, understanding your exposure history is an important first step. Call (800) 505-6000 or fill out our contact form to learn more.
