"Ben & Brady did an outstanding job installing our attic insulation. They were professional, courteous, kept us informed on their progress and cleaned the work area before leaving. From my first call to Ideal Home Energy thru the quoting process with Forrest and during the actual job, it was great to work with their organization. So happy with the entire process! Eric L."

"Guardian Insulation was great to work with. Everything was explained in depth and choices broken down with plenty of info. We already feel a difference and notice that our furnace isn't running as often, even though we are in a cold spell. They cleaned up too. Would highly recommend!"

Insulation FAQs, answered by experts

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Minimal but regular checks can ensure maximum thermal performance.

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.

For your safety, you should always wear a mask when cutting batts of fiberglass insulation. We also recommend wearing eye protection, safety gloves, and long sleeves to protect your skin. Properly suiting up helps you avoid several fiberglass issues, such as cuts from the tiny shards of glass and inhaling small bits of fiberglass.

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.
