Smoke Detector Installers FAQs, answered by experts

Burning a single palm tree stump, if you’re careful, is technically doable DIY. However, you should always take precautions to control the fire and do research if you’re burning multiple types of trees. 

Some trees, such as ornamental trees, black cherry, and some oak trees, release toxins into the air when burned that can be irritating to your lungs (or even dangerous) to breathe in.

Hard materials like glass, metal, and hardwood floors, washable fabrics, and undamaged electrical appliances can often be salvaged after a fire, although it depends on the extent of the damage. For washable fabrics, make sure to use a phosphate mix during the washing process to extract the smoke smell. There are a few things you should throw away after a fire, like canned foods and cosmetics, even if they don’t look like they’re damaged.

Depending on who’s doing the estimating, about 22,000 to 25,000 chimney fires happen each year in the United States. Given the fact that millions of Americans have fireplaces (and chimneys), that means chimney fires aren’t exactly common—but they’re not rare, either. Since they’re so dangerous, it’s important to take precautions to prevent them.

Costs depend on stone type, surface condition, labor, and whether sealing or deep cleaning is required.

Most projects take 1-8 weeks, depending on structural repairs, cleaning, and air quality restoration.
