"I've had ice dams for years. I finally researched it enough to realize it was an insulation problem (I wish I had been smart enough to figure it out sooner). Anyway Speciality Insulation came out and gave me a truly reasonable estimate. The technician found an uninsulated heating pipe, missing batts, in addition to the original find of inadequate insulation. They fixed all of that. I have a room that was perennially cold, it's warm now, no ice dams and I am sure my gas bill will go down. They cleaned up after themselves and were very pleasant people. Very pleasant, efficient and did what they said they could do for an affordable price."

Insulation questions, answered by experts

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

You do not always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.
