Why Won’t My Garage Stay Warm?

Some owners have a separate heating system that may be inside their garage, which we recommend checking first. To determine if your heater is working properly:

1. Adjust the thermostat up 10 degrees
2. Come back after an hour and see if you notice a difference
3. If the temperature feels the same or cooler, it may be time to replace your heater
4. If you do notice an increase in temperature, it may be one of 3 things which we’ll discuss further. 

Damaged or compromised seals can cause temperature regulation issues with your door. We wrote a blog about specific reasons why your garage door seal might be compromised, it might help with diagnosing the problem a bit more closely.

In summary, inspect the seal both when the door is wide open and closed. Check for cracks, holes, any spots where it’s uneven, etc. If you notice any issues with it, it may be time to replace that seal, which we can change out for you, just give us a call! 

Many people forget the windows on their garage door have seals, which just like the door seals, can eventually become ineffective. In rare cases, the seal around the windows can cause air to get through the border of the window.

To check if this is the issue, close the garage door and run your hand along the back of the window. Should you feel air coming through, you likely will need the window or windows replaced. We don’t specialize in garage door window install or replacement, so we’d recommend calling the door manufacturer directly and ask what they recommend for glass replacement. 

Hopefully this isn’t the cause of your garage not staying temperature regulated, but it is possible. Physical cracks in the door or foundation definitely can lead to major insulation issues. Once you determine your heater is functioning (if you have one) and make sure the seals are not compromised, inspect every spot along the door, walls, and ceiling for any cracks, soft spots, or holes. If you notice an area or areas where you can feel cooler air coming through, you will likely need that spot patched, insulated again, and sealed off.

We recommend finding a certified contractor for any work involving the drywall, foundation, or ceiling. For the door itself, head to your local home improvement store and an associate will be able to assist. Let them know you’re looking to seal a crack/hole in your door plus the door material and they should be able to assist.
