"The guys were really neat. They set up a tunnel from the attic to the back door. There really wasn't much to clean up after. They vacuumed out the old insullation and laid in new. It's hard to say if they did a good job in the attic, because I don’t know what its supposed to look like. They were in the attic almost about 7 hours. The only issue was that they said the senior discount on their Angie's list page must be old so they didn't honor it."

Insulation questions, answered by experts

Each insulation type has its own R-value, so you’ll want to weigh the pros and cons of your materials when deciding which one will give you the best value. Energy.gov recommends you choose a pipe wrap that’s at least one inch thick. The International Code Council (ICC) suggests choosing a pipe material with an R-value of at least 3.

You don’t need to staple insulation, as your drywall and studs will hold it into place. But if you already have a staple gun and staples lying around, it can help keep the product in place and avoid any shifting. But, most experts agree it’s an unnecessary step.

If you’re adding a vapor barrier, you will need to staple that in place.

For a truly DIY solution to protect your outdoor faucets from freezing, you can craft your own faucet sock out of spare rags, plastic shopping bags, and duct tape—but this method might not be as effective (or attractive) as store-bought. If you choose to DIY your own outdoor faucet cover, be aware that rags, old towels, and other fabric you might use to wrap the faucet can absorb water like a sponge and could cause problems if it freezes.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.
