"We have an extremely small crawl space in the attic and they were able to spray in the insulation in the full attic (except the garageâ ¦donâ t know why garages arenâ t included). Love that they installed air vents prior to blowing in the insulation so thereâ s plenty of ventilation in the attic. They worked quickly and only took a few hours. We definitely can feel the difference and canâ t wait to see the difference in our electric bill."

Drywall Insulation FAQs, answered by experts

A nail in drywall cannot hold very much—usually only a few pounds. A nail in a stud can add support and hold around 20 pounds. If you are trying to hang something heavier, get some help from drywall anchors—toggle bolts are very strong and able to withstand more weight.

Cracks, water damage, and holes from fixtures or impact.

Yes, you can hammer a nail into a wall stud. But before you do, it’s important to confirm that you’re actually nailing into a stud—and not wiring, pipes, or ductwork. To check, find a few more studs in the wall, then measure to make sure they’re either 16 or 24 inches apart.

It’s highly recommended to use studs for a TV mount. The last thing you want is to be watching your favorite show when the TV falls off the wall. Studs are much stronger than drywall and quite a bit stronger than drywall anchors but, if you can’t find the studs or there simply aren’t any where you need them, you can use drywall anchors. It’s extremely important to make sure the anchors are rated for the load of the TV. We recommend using anchors that are rated far beyond the weight of whatever you’re hanging. Our suggestion is metal drywall toggle anchors. 

Drywall mudding can be done in one day if the project is small and the desired effect isn’t too complex. If you need multiple layers of mud, one day may not be realistic. But a single room that requires little more than joint compound on the seams and screws can be done in a day or two.
