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: Does ductwork need to be insulated in conditioned space?

• <div><p>There are no building codes requiring HVAC duct insulation for ductwork in conditioned spaces, like walls or floors. Unfinished basements are also exempt from this requirement. However, many homeowners choose to insulate their home's ductwork in some or all of these areas to increase the system's efficiency and reduce potentially harmful areas of condensation.</p></div>

Q: Can you add spray foam insulation to an existing home?

• <div><p>If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn&rsquo;t possible unless you remove most of the drywall.</p></div>

Q: Will a dehumidifier stop condensation on ductwork?

• <div><p>A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won&rsquo;t solve the problem. </p></div>

Q: Do you need a vapor barrier under metal siding?

• <div><p>When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.</p></div>

TL;DR: Craigo lost a legal suit against me and has refused to pay. I contacted Craigo on a referral that he could cut a door in the basement of our house. Though I only got him to talk on the phone once, he agreed he could do the job and then communicated primarily over text after that. He...
