An affordable insulation solution for year-round garage use
How To Affordably Insulate Your Garage
Our garages serve many purposes: parking our vehicles, storing our stuff, and often, working or living activities. Depending on the time of year, the weather makes a big difference in how much time we spend—and what we can get done—there. In addition, if any room in your house is adjacent to the garage, whether it’s above or next to it, cold in the winter (and heat in the summer) can spill over into that room, making it less than comfortable, even before you open that door to the house.
If your garage or adjacent room is getting too cold or too hot for comfort, it’s time to consider insulation. An uninsulated, unsealed garage can be inefficient, in addition to being a potential health hazard.
The cost of spray foam insulation is one of the top worries for our customers. We have a saying: “Estimates are free; heating is not.” When you want to see what your home insulation will cost, the best way is to start with a FREE Estimate. We’ll give you a list of all the costs, and your options: insulation type, areas that are important to insulate, and more.
We’ll compare costs with Spray Polyurethane Foam (SPF) in your attic and walls. Our customers love the low cost of SPF. We’ve even had some customers compare the cost of applying spray foam by themselves to the cost of hiring us to do it. Every time, it has turned out to cost less to hire us!
If needed, we can even talk about treating only one (or only sections) of your home or building at a time, so you can spread out the work—and your costs—over time. Tell us your goals, and we’ll work with you to make sure you get everything you want for your budget.
Do You Need Garage Insulation?
The benefits of a well-insulated home are often compromised by a leaky garage, through air seepage, poorly insulated walls, leakage of dangerous fumes, or lack of fire protection. If your comfort in rooms adjacent to your garage is less than ideal, or if you’re letting in too much very cold air (in winter) or hot air (in the summer) every time the garage/house door opens, you’re the perfect candidate for insulation.
A less-realized benefit: with an insulated garage, you may also be able to get more utility from your garage, with enough comfort to work at a workbench, work on your vehicles, or pursue an “outdoor” project that won’t work inside your house.
A nominal level of insulation will also allow you to heat your garage up to 40 degrees, enough to thaw the cars off and keep it above freezing. Something we would all love through our cold upstate winters! And it keeps the cost to insulate your garage very reasonable.
Where Should You Insulate?
Between The Garage & Home Interior
As a homeowner, you may have already considered garage insulation on the wall between the garage and your home’s interior. This will definitely save you on energy costs, preventing escaping air and heat loss through this barrier.
By law, insulation in this wall also needs to be fire-rated (due to the storage of combustible liquids in your garage, coupled with a typical lack of smoke detectors there). This additional safety layer is a great benefit for you and your family.
Many people forget to look up: insulation in your garage’s ceiling, especially if you have a storage space, or even a room, above your primary space, is an essential part of sealing the space.
Finally, if you’re insulating your garage, you’ll want to insulate the door as well, easily accomplished with ready-made kits that seal the doors and prevent air gaps.
Our Recommendations for Garage Insulation
There are several options for insulating your garage, and which you choose depends on your budget and specific needs for your space:
Though this cotton-fiberglass material is fairly inexpensive and easy to install (place it between the studs, staple a vapor barrier to cover it), it’s only effective if you install drywall on ceiling and walls as well. This adds to your cost of materials and labor.
If you already have drywall installed but don’t have it insulated, then blown-in insulation may work best. We can create temporary holes in the walls, pump in a cellulose insulating material, and then patch the openings. This approach is relatively fast, and cost will depend on your space.
Spray Foam Insulation
For unfinished walls and ceiling, a nominal amount of spray foam can seal your garage quite well, and can be done relatively quickly. About 1.5” of Closed Cell Foam will keep your insulating cost very reasonable, seal your garage from the elements, and insulate any space above or next to your garage from the outside air.
Protecting Your Investment
In addition to insulating the walls and ceiling, we make sure everything is sealed off (sealing carefully to the base of walls, around any windows, electrical outlets, and the garage door), and recommend any additional measures we may not cover, such as weatherstripping the door leading into the house; recommending the best door to the house (for fire safety and best sealing), and insulating and sealing around the garage door.
