Patio Door Letting in the Cold? Time for a Fix
As winter hits Ottawa, it’s hard to ignore the drafty spots in your home—especially around your patio door. If you’ve been noticing a chill sneaking in, no matter how high you crank the heat, it might be time to check on that door. Patio doors are great for bringing in natural light and connecting your living space to the outdoors, but when they’re not sealed properly, they can let all the warmth escape. Alex Windows can help make sure your patio door is keeping the cold out, so you can enjoy the cozy warmth of your home during those chilly months.
In this guide, we’ll look at the signs your patio door might be letting in the cold, why it’s happening, and how you can fix it so your home stays warm all winter long.
Signs Your Patio Door is Letting in the Cold
Before diving into repairs, it’s important to figure out if your Patio door is the problem. Here are a few signs to watch out for:
Gaps Around the Doorframe
If you can see or feel gaps around your door, that’s a major red flag. These small openings can let in a lot of cold air, especially when temperatures really drop.
Condensation on the Glass
Noticed some fog or condensation on your patio door glass? This could be a sign that the door’s insulation is no longer doing its job, letting cold air in.
Wind Blowing Through
One of the biggest giveaways: feeling wind blow through your door—even when it’s closed. This usually means your seals or weatherstripping are worn out and need replacing.
Colder Floors Near the Door
If the floors around your patio door feel significantly colder than the rest of your home, that’s another sign of air leakage. The cold air could be making its way in through cracks or poorly sealed areas.
Higher Heating Bills
If your heating bills have been higher than usual, it could be because your patio door is allowing warm air to escape. When doors don’t seal properly, your heating system has to work overtime to maintain the temperature inside.
Why Is Your Patio Door Letting in the Cold?
There are a few reasons your Patio door could be letting in that unwanted cold air. Let’s go over the most common ones:
Worn-Out Weatherstripping
Weatherstripping around your door creates a barrier between the inside and outside of your home. Over time, it can become cracked, torn, or worn out. When this happens, air can easily slip through. Fortunately, weatherstripping is easy to replace.
Broken or Worn Seals
The seals around the edges of your patio door can also wear out over time, especially with extreme weather. Once they’re damaged, they won’t do a good job of keeping the cold air out.
Poor Installation
If your patio door was installed incorrectly or wasn’t properly aligned, you might have gaps in the frame. These gaps can lead to drafts and temperature fluctuations inside your home.
Single-Pane Glass
Older patio doors might have single-pane glass, which offers little to no insulation. Single-pane glass is a major heat loser, so it might be time to upgrade to double-pane for better energy efficiency.
Damaged Door Frame
If your door frame is damaged, it can cause misalignment and gaps around the door. This can also contribute to cold air sneaking in.
How to Fix Your Drafty Patio Door
Now that you know why your Patio door might be letting in the cold, here are some simple fixes you can try to solve the problem:
Replace the Weatherstripping
If your weatherstripping is worn or damaged, replacing it is one of the quickest and easiest fixes. Simply remove the old stripping, clean the frame, and install new weatherstripping that fits snugly. It’s a simple fix that can make a big difference in keeping the cold air out.
Replace the Door Seals
If the seals around your door are compromised, you can replace them as well. Just measure the frame, buy the correct size seals, and replace the old ones. This will help create a better barrier against the cold.
Upgrade to Double-Pane Glass
If you have an older door with single-pane glass, upgrading to double-pane glass can significantly improve the door’s insulation. This will help keep your home warmer and your energy bills lower.
Realign the Door
If your patio door is misaligned, it might need to be adjusted. A professional from Alex Windows can help realign the door and seal any gaps around the frame. This ensures it closes tightly and prevents drafts.
Install a Draft Stopper
For smaller gaps, a draft stopper at the bottom of the door can do the trick. These are affordable and easy to install, and they’ll help block out the cold air.
Why Fixing Your Patio Door Is So Important
Not only will fixing your Patio door help keep you warm, but it also saves you money in the long run. A properly sealed patio door means your heating system won’t have to work as hard, leading to lower energy bills.
