Asbestos in Older Homes and What to Know Before Renovation Projects
Renovating an older home often comes with surprises. One of the most serious is the presence of asbestos in older homes. This topic matters, especially for homeowners who enjoy DIY projects or plan to add storage, shelving, or built-ins during renovations.
We were asked by a reader to address asbestos safety, and we agree it is an essential conversation. Understanding the risks before starting a project can protect your health, your household, and anyone working in the space.
Why Asbestos Is a Serious Risk in Older Homes
Asbestos was commonly used in construction materials for decades because it was fire-resistant and durable. Unfortunately, asbestos exposure is now known to cause severe illnesses, including mesothelioma, lung cancer, and asbestosis.
There is no cure for asbestos-related diseases. The risk increases with each exposure, which is why strict federal and state regulations exist to control how asbestos is handled and removed.
Never Attempt DIY Asbestos Removal
The most important rule when dealing with asbestos is simple. Do not handle it yourself.
Handling, disposing of, or attempting to recycle asbestos-containing materials without proper licensing puts everyone at risk. Even disturbing materials can release microscopic fibers into the air. Once airborne, those fibers are easily inhaled and difficult to contain.
If you suspect asbestos in your home, do not cut, sand, drill, or remove the material. Lightly misting the area with water can help reduce fiber release until a licensed professional evaluates the situation.
Why Professional Asbestos Abatement Is Required
Licensed asbestos abatement professionals are trained to assess, contain, and remove asbestos safely. They follow strict protocols designed to protect workers, occupants, and the surrounding environment.
Violating asbestos regulations can result in serious fines and legal penalties. These laws exist for good reason. Even television renovation shows routinely pause projects and call in specialists when asbestos is discovered.
What Proper Asbestos Abatement Involves
Professional asbestos handling includes several critical steps:
Project assessment and permitting
Licensed professionals evaluate the scope of the project and secure the proper permits required by local authorities.
Work area preparation
The area is sealed with plastic sheeting. Negative air pressure systems prevent fibers from escaping into the rest of the home. Warning signs are posted to alert others.
Personal protective equipment
Workers wear N-100 or P-100 respirators and full protective clothing to prevent exposure.
Controlled removal and cleanup
HVAC systems are disabled. Wet methods and HEPA vacuums are used to minimize dust. The area is thoroughly cleaned once removal is complete.
Safe disposal of asbestos waste
All asbestos-containing materials are wetted, double-bagged in heavy plastic, sealed in labeled containers, and transported to designated asbestos disposal landfills.
Decontamination procedures
Workers use specialized decontamination units to remove contaminated clothing and equipment, preventing fibers from being carried outside the work site.
Plan Before You Renovate
If you own an older home, asbestos should always be considered before starting renovation projects. This is especially important for DIY work involving walls, ceilings, flooring, insulation, or old adhesives.
Planning ahead allows you to pause, assess, and bring in professionals before a small project becomes a serious health hazard.
