How Much Does it Cost to Insulate a Garage?

Homeowners shouldn’t overlook the benefits of garage insulation, which may cost between $1.73 per square foot and $3.13 per square foot for this year.

The actual price will depend on the price of materials and cost of labor, as well as ancillary expenses for flooring insulation like adding garage epoxy. In Utah, some of the available types of insulation include cellulose, spray-foam and rigid-foam insulation.

Breakdown of Expenses

A basic garage insulation will cost between $165 and $180, while a better one will require you to spend from $225 to $255. The best insulation should only cost between $285 and $340. However, the size of your garage will affect the overall price aside from your location, labor fees, and cost of materials. You shouldn’t try to cut corners on the installation price by doing it yourself or hiring an inexperienced contractor.

It might cost you double the amount when you find out faulty installation work, which will require another contractor to fix it. When choosing among different service providers, it’s always better to hire a licensed and insured professional. Ask for up to five quotes or estimates to compare the best prices. Make sure that companies offer these for free before making inquiries. Do this during late fall or early winter if you want to pay lower prices.

Rates are usually down during this period of the year because of lower demand. Don’t forget to insulate your garage door and not just the walls or ceiling. While garage insulation requires a professional, you could insulate a garage door by yourself with the use of a basic kit.

Garage Door Insulation

Insulation for a garage door is likely more necessary for attached garages than a stand-alone one, as the former is connected to your home’s heating and cooling system. Inspect the edges and seams on doors to see if there are large gaps where heat can escape or enter, which would require you to use weatherstripping particularly on the bottom edges.

Injected foam insulation is one of the common and cheapest ways to insulate doors, especially if you have metal ones. You could also cut panels of rigid-foam insulation and apply the pieces into each gap or along the door’s edges. Rigid foam is a good option for garages that double as a workspace. Remember that not all types of rigid foam are fire-resistant.

Another important thing involves air sealing, which you could do by applying a weather seal strip on the top and sides of the garage door. Use a rubber gasket to cover the bottom part. If all of this seems like tedious work, then hiring a handyman to do it will save you time and effort.

While it’s possible to spend as low as $165 for a garage insulation, try to spend up to 15% more to take other factors such as a complex garage layout into account. If you live in a place with a desert-like climate, you should consider hiring a company that specializes in insulation for this type of environment.
