Q: Do I need to air seal my attic before installing insulation?

• <div><p>Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks.

Q: How long does it take to install or upgrade insulation?

• <div><p>The time required for insulation installation can range from a few hours to a few days, with most projects taking 1-3 days to complete. The final duration depends on the project's size and complexity, the area size, and the type of insulation being installed.</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>

Very thorough home inspection. His findings allowed us to renegotiate the sellers price where they were once firm and nonnegotiable. After the inspection he spent a good 45 minutes answering questions, easing our fears and helped guide us in the right direction as to what needs to be done next....

If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.
