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>

Does bathroom insulation need a vapor barrier?

• <div><p>Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.</p></div>

Q: What insulation generally has the highest R-value?

• <div><p>Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they&rsquo;re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It&rsquo;s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.</p></div>

Q: Is ceiling insulation worth it?

• <div><p>Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2. </p></div>

Q: Do professionals handle attic, wall, and floor insulation?

• <div><p>Yes, professionals install and upgrade insulation for all home or business areas.</p></div>

I had him install my coffee bar with countertop in my dining room, he did an exceptional job! My walls were very crooked and I didn't want any backslash, he perfectly scribed the top and trimed the cabinets so that you wouldn't even notice that the wall was off! Would definitely hire again for...
