Building a home or renovating a space is a big deal. You want materials that are safe, reliable, and built to last. But not every product on the shelf is as safe as it seems. Some building materials are being pulled from stores, often without much notice. This matters because what you use in your home can affect your health, your wallet, and even your home’s value. Knowing which materials are disappearing—and why—can help you make better choices for your next project.
1. Asbestos-Containing Insulation
Asbestos was once everywhere. It’s fire-resistant and insulates well. But it’s also dangerous. Breathing in asbestos fibers can cause lung cancer and other diseases. Many countries have banned it, but some older products still show up in stores or secondhand. If you’re renovating, check for asbestos in old insulation. Don’t try to remove it yourself. Hire a professional.
2. Lead-Based Paint
Lead paint is another material that’s slowly disappearing. It was banned in homes in the late 1970s, but some products still contain trace amounts. Lead is toxic, especially for kids. It can cause learning problems and other health issues. If you’re working on an older home, test for lead paint before sanding or scraping. Use certified lead-safe products and follow safety guidelines.
3. Formaldehyde-Laden Plywood
Plywood and particleboard often use glues with formaldehyde. This chemical can leak into the air and cause breathing problems. Some brands now offer low-formaldehyde or formaldehyde-free options. But many stores are quietly removing high-formaldehyde products due to stricter regulations. Look for labels like CARB Phase 2 or “formaldehyde-free” when buying wood products.
4. Polyvinyl Chloride (PVC) Pipes
PVC pipes are cheap and easy to install. But concerns about chemicals leaching from PVC have led some suppliers to pull them from shelves. Alternatives like PEX or copper are becoming more common. If you’re replacing pipes, ask about safer options. Some cities are even updating building codes to limit PVC use.
5. Chinese Drywall
In the early 2000s, some drywall imported from China was found to emit sulfur gases. These gases can corrode wiring and cause health problems. Lawsuits and recalls followed. Most stores have stopped selling this drywall, but some leftover stock may still be around. Always check the source of your drywall, especially if you’re buying surplus or discounted materials.
6. Creosote-Treated Railroad Ties
People used to use old railroad ties for landscaping. They’re cheap and last a long time. But creosote, the chemical used to treat them, is toxic. It can seep into soil and water. Many garden centers have stopped selling these ties. If you want a rustic look, look for untreated or naturally rot-resistant wood instead.
7. Certain Spray Foam Insulations
Spray foam insulation is popular for its energy-saving benefits. But some types contain chemicals that can cause breathing problems during and after installation. Reports of headaches and respiratory issues have led some stores to pull certain brands. If you’re considering spray foam, ask about the chemical content and look for low-emission products.
8. Pressure-Treated Lumber with Chromated Copper Arsenate (CCA)
Pressure-treated wood resists rot and insects. But older versions used CCA, which contains arsenic. This chemical can leach out, especially in Code Playgrounds and gardens. Newer treatments are safer, but some old stock may still be on shelves. Always check the label and avoid CCA-treated wood for any project that touches soil or food.
9. Mercury-Containing Thermostats
Mercury is toxic, even in small amounts. Older thermostats and switches often used mercury. Many stores have stopped selling these, but you might still find them in clearance bins or secondhand shops. If you’re replacing an old thermostat, recycle it properly. Don’t just throw it in the trash.
10. Vinyl Flooring with Phthalates
Vinyl flooring is cheap and easy to clean. But some types contain phthalates, chemicals linked to health problems. New regulations are pushing stores to remove these products. If you’re shopping for flooring, look for phthalate-free labels. There are safer vinyl options, as well as alternatives like linoleum or tile.
Why Paying Attention to Building Materials Matters
Building materials are always changing. What was common a few years ago might be off the shelves today. This isn’t just about trends. It’s about safety, health, and long-term value. When you know which materials are being pulled and why, you can make smarter choices. You’ll avoid costly mistakes and protect your family. The next time you shop for building supplies, ask questions. Read labels. Don’t assume that everything on the shelf is safe or up to date. The right materials make a difference.
