"Highly professional and extremely accommodating. There were bats in my attic when they went in to redo the insulation. They calmly (as they could) told me the situation and came back at a later time with no added cost. Did an excellent job, and had a incredible attitude throughout. Cannot recommend enough. Thank you!"

"They provided blown in insulation for my home. They were able to schedule an appointment quickly and showed up on time. Their price was approximately market price (not a bargain). They did a satisfactory job, but their cleanup left a lot to be desired and they had to quickly repair something that was accidently damaged during the blow-in process. The employees were nice and professional, but didn't seem to be experts in the field. Their office was helpful in answering questions and handling payment processing and energy tax rebate questions."

Insulation questions, answered by experts

Minimal, mainly occasional checks for damage or mold in extreme conditions.

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

Energy-efficient homes generally have higher appraisals and appeal to buyers.

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.
