Does bathroom insulation need a vapor barrier?

• <div><p>Yes. Bathroom insulation requires a vapor barrier.

Do insulation companies need to be licensed?

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.

Our solar electronic gate is very nice. It works well. It needs a slight adjustment and a latch. I did not know we would need a latch. I guess the installer did not know either. He did not have one at the time of installation so that is the reason for the 4.5 stars versus the 5 stars.
