"The representative was very knowledgable about the scope of work. I called him for the replacement of the attic insulation due for rats. I had pest control guy tell me my attic insulation had to be replaced. The rep, Guy, told me that wasn't what I needed. He told me that replacement the attic insulation would not solve my rats. He gave me names of good pest controls. Guy said to contact them before spending thousands of dollars for rats in my attic. Thank you Guy."

Insulation questions, answered by experts

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.
