"The GIC team was very prompt and knowledgeable. They were very neat and cleaned up well after themselves. We had our attic insulated and foam sprayed on rim joist and basement crawlspace. We noticed the house to be much quieter immediately. So glad we had this done in January before the -22 degree temperatures hit. Can't wait to see the effect on summer air conditioning bills."

"My experience with Victory Insulation went extremely well. They installed blown fiberglass insulation in my attic. The installation crew was very helpful and easy to work with. Since the install, my family has already noticed our hvac running a lot less within the last few months. I highly recommend working with Victory."

Before we started you could see the ceiling joists. We made sure this insulation was up to EnergyStar recommendations, R49 (about 18" of blown fiberglass insulation).

This is how the attic insulation looked once we were almost done.

Insulation questions, answered by experts

Fiberglass is considered dangerous only if your skin comes into contact with it or if you breathe in any fiberglass particles. This is because fiberglass is literally made of tiny fibers of glass that can cut your skin and your organs. While there aren’t many long-term effects, it’s still important to take all the proper safety precautions when working with fiberglass.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

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.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.
