How do I add insulation to existing walls?

• <div><p>If you need to insulate behind finished walls, the best option will likely be to have an insulation professional install <a href="https://www.angi.com/articles/blown-in-insulation.htm">blown-in insulation</a>. The installation requires small holes cut in your wall, after which the installer can blow loose-fill insulation into the void. After the installation, you’ll have minor drywall patching, which shouldn’t cost more than <b>$100</b>. Compared to ripping down the existing drywall, using a different type of insulation, and replacing and finishing the drywall, this should save you hundreds or even thousands, depending on the size of the room you’re insulating.</p></div>

Do insulation companies need to be licensed?

• <div><p>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 <a href="https://www.angi.com/angi-license-check.htm">license lookup tool</a> 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.</p></div>

Is bubble wrap or dish foam better?

• <div><p>Bubble wrap is better for moving since it can be cut to size, whereas dish foam comes in precut sheets that are harder to manipulate. However, if you’re packing items like dishes, wine glasses, picture frames, or mirrors, dish foam will protect them better. Ensure you measure your box beforehand so you know what size dish foam to purchase. </p></div>
