I would highly recommend Greg Hill. He’s a great guy and he knows what he’s doing. We appreciate all the work he did on our new church project. He took a 112 year old building and turned it into a modern day sanctuary, kids church and offices. We are totally loving it.

Doorbell Installation questions, answered by experts

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.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
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.

Costs depend on area size, material thickness, and site preparation needs.

Periodic checks for moisture or pest issues ensure consistent performance.

Reflective and high R-value batt or roll insulation are often considered energy-efficient, offering significant thermal resistance benefits.
