How to Increase the Your Garage’s Energy Efficiency

When it comes to energy efficiency, we all tend to think about the inside of the home. One often forgotten room, however, is the attached garage. The garage is notoriously the most energy inefficient room, draining homeowners of hundreds of pounds in utilities each and every single year. Fortunately there are a number of things that homeowners can do to boost their garage’s energy efficiency without breaking the bank.

Caulking and Sealing

A tube of caulk may set you back a few pounds, but it can save you many more over the course of the year. Many garages – particularly older ones – are not built with the proper compressible foam between its lower framing and the concrete floor. Over time, this connection will swell in hot weather, shrink during the cooler months, and ultimately leave gaps and spaces which allow the outdoor air to flow in.

Homeowners who are armed with a tube of caulking can get down on the ground and begin caulking this connection to prevent air leaks. A latex or silicone based caulk or a foam sealant will do.

The next area of concern: the door between the home and your garage. To fix this problem, all a homeowner needs is some inexpensive weather-stripping. The weather-stripping should be installed around the entire door frame and be:

  • Pliable
  • Intact
  • Able to form a solid seal

Using a bright light and shining it around the door is a great way to see if there are any air leaks around it.

Homeowners will also need to see if the threshold is properly sealing at the bottom of the door. If not, a draft stopper can be used to help keep the door insulated. Finally, while you still have the caulk on hand from your earlier project, be sure to caulk the trim around both the inner and outer portion of the door. Air can and will find its way into your home or your garage if not properly sealed.

Sealing the cracks in your garage’s cement floor with concrete sealant will go a long way in keeping cold air and gasses from passing through into you garage. Homeowners can pick up a tube of this sealant for a few pounds at their nearest home improvement shop.


Older garages do not have appropriate insulation, meaning that the items kept within the garage are subject to the many less desirable conditions that changes in climate bring. Homeowners can choose to have the walls of the garage insulated. This is typically done by having appropriate R-value insulation rolled down and in between your joists. Other companies may choose to blow an insulating material through a small hole in the drywall to bolster your garage’s insulation.

The walls aren’t the only part of the garage which should be insulated. The garage door should also provide appropriate insulation to keep the inside of your garage at an optimal temperature and in optimal conditions. Hollington Garage Doors in Essex offer an extensive range of insulated doors and in different materials. Steel is the most commonly insulated door, though plastic, timber, or other materials can also bring added insulation to your garage.
