Why Remove Your Old Insulation?

Monday, June 5th, 2017 by Gwen Hurd


Old fashioned insulation is wild. If you’ve ever had the privilege to renovate an old house, or you’ve seen renovation projects on TV, you know what I’m talking about. My house was built sometime in the 1750s and I’ve found some really inventive insulation materials between the walls and under the floorboards. While the majority of my house was insulated with newspaper, I also found animal hair and corn cobs.

At Dr. Energy Saver Northshore, we do not recommend insulating your home with animal hair and corn cobs. I think we can all agree that this kind of “insulation” needs to be removed ASAP. But what about old fiberglass insulation? Why not keep it? It isn’t hurting anyone, so what does it matter?

Well, you might be fine keeping that fiberglass where it is. If your fiberglass insulation is in good condition, functioning properly, and tucked away in your walls, you might want to leave it there. And if it isn’t functioning properly, Dr. Energy Saver can add more insulation (and R value) to already insulated walls, without having to remove old insulation.

If your fiberglass insulation isn’t in good condition, it might be causing you problems. Here’s why your old insulation might need to be removed:

  1. Mold/Mildew – Fiberglass insulation can get ruined by moisture. If you’ve ever seen photos of nasty attics or basements, it looks like melting dirty cotton candy. Don’t worry, you won’t want to eat it. Since mold and mildew can be harmful to your health, it doesn’t make sense to keep it in your home.
  2. Dust – Many people have dust allergies, but most people would agree that a dusty environment isn’t ideal. If you don’t have allergies to dust, you still probably wouldn’t want to live in a dusty home. If your once pink fiberglass insulation is now tan and dusty… remove it. All that dust isn’t healthy, even for those without allergies.
  3. Critters – Rodents and bugs love fiberglass insulation. It’s warm, easily shreds, and the perfect material to nest in. If critters have used your insulation as a home, you’ve got to remove it. Rodents carry disease and bugs are creepy (unless you like bugs?).

This is a photograph of some attic insulation we’d recommend removing:

You can see that it is in pretty rough shape, most likely animals have been in it, and it’s undoubtedly incredibly dusty. If your insulation looks like this, give us a call, we can remove and replace it!
