Should I insulate my attic?

If you do not have the right level of attic insulation, it may be to blame for the high cost of keeping your home comfortable. The suggested R-Value of insulation in the attic of your home is R49 to R60. Even if you currently have some insulants present in your attic, you may not have the right level to control your home’s interior climate. The experts at Pro can inspect your attic and ensure that your home has the right levels of attic insulation.

What does it cost to insulate an attic?

There are many factors to consider when you talk about the cost to insulate your attic. The materials you use and the amount you need to reach the right R-value are only part of the cost. Does the old insulation need to be removed? Will the ventilation need to be upgraded to avoid moisture build-up and mold? Without the answers to these questions and more, it is difficult to provide an accurate estimate of your project’s costs.

Attic insulation can pay for itself!

Beyond the cost of the installation project, there is the money you are losing each month in heating and cooling bills.

If your attic insulation is not the right R-value your heaters and air conditioners have to work that much harder to keep your home comfortable. Up to 30% of the energy spent heating or cooling your home can leave through the attic.

The right levels of insulation will stop this thermal loss and lead to energy savings each month that will offset the cost of the project.

What R-value do I need for my attic?

The suggested R-value of insulation in the attic of your home is R49 to R60. Even if you currently have some insulants present in your attic, you may not have the right level to control your home’s interior climate. The experts at Pro can inspect your attic and ensure that your home has the right levels of attic insulation.

What is the best type of insulation for an attic?

The best insulation to use on your attic depends on the shape & space of your attic, your budget, and what you already have installed. The insulation experts at Pro can help you determine what is the best option for your unique project. Pro currently offers four types of insulants that can help slow the loss of thermal energy from your home’s attic.

Stabilized Cellulose

Stabilized cellulose is our exclusive blown-in insulation. The stabilized nature of this product means that it is guaranteed not to settle or shift, meaning you will have proper coverage for decades to come. Made from 100% recycled materials this insulant is the greenest product we use.

Cellulose Insulation


Fiberglass isulation is available as loose-fill and batt. The most common form of insulation used in Michigan homes. You may recognize it from the unique pink color. It is made of glass fibers that are woven together with a binder. This gives the insulant a wool-like texture.

Fiberglass insulation


Denim insulation is available as loose-fill and batt. This insulant is made using excess materials from denim factories. The product is completely recyclable and has a low waste production process. It also does a better job of noise reduction over other insulants.

Spray Foam

Spray foam insulation is available as open-cell and closed-cell. This form of insulant gives the best permanent coverage out of all the options. This product is a foam that expands onto the surface it is sprayed on. This will seal up all spots where drafts may be coming from.

Can you over insulate an attic?

Yes, you certainly can put too much insulation into an attic space. It may seem counterintuitive, but too much insulation can create issues with air moving through the space. Proper ventilation is as important as having the proper R-value. Without it, moisture can build up throughout your attic, leading to mold and a loss of indoor air quality.

Can you put new insulation over old?

Generally, there is no need to remove old insulation before installing your new product. Except for instances where the old insulation has not become filled with moisture or mold. In these cases, it must be removed to avoid damage to the home. Another situation where the old insulation will need to be removed is if you are replacing batt with spray foam.

What Our Insulation Customers Are Saying

  • A positive experience. The work crew arrived as scheduled. Workers were prompt in setting up and going through the step-by-step process on adding insulation to the attic. I was encouraged to ask questions and to watch as they worked. Clean up of all work areas was performed. We received a follow up call, after the crew had left, verifying my satisfaction.

  • We had our family room insulated by Pro. They arrived on time and performed the work professionally, and in a timely manner. When they were finished, they made sure our property was in the same condition as when they arrived. We did have an issue with the inside trim molding on our patio door wall pulling away from the door wall, but the company that installed our patio door wall came out and fixed it. We have noticed that our family room is warmer than before. We are satisfied with the job Pro did for us and would recommend this company to anyone.
