Insulation questions, answered by experts

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Pipes in your house can freeze after six hours or so if you lose power and temperatures are below freezing. You can prepare for potential power outages by winterizing your pipes with insulation. Also, whenever temperatures drop below 20 degrees Fahrenheit, turn your faucets on very low and leave them dripping until temperatures rise.

Most projects take 1-3 days, depending on area size and insulation type.
