How to Seal Doors for Winter
1. Tighten Hinges
It’s not uncommon for air leaks to come in if the door’s hinges have moved from their original placement. Before you do anything else, check for this: simply lift the door by the doorknob. If the door moves upward, tighten the top hinge screws within the door jamb and see if this solves the problem.2. Add a Door Sweep
Installing a door sweep along the bottom of all exterior doors is a quick and easy way to keep out unwanted air leaks during the winter by creating an air-tight seal at the bottom of your door. In general, door sweeps consist of a rubber strip attached to the front of the door or a brush-like strip that runs along the bottom. If your door sweep is bent, broken, or otherwise damaged, chances are it’s allowing drafts in. A well-installed door sweep can keep cold air from leaking under the door, and you can easily attach one without needing to trim your door. You also can find sweeps on rollers that will compensate for an uneven floor.3. Seal Gaps
Allowing gaps in exterior doors, including the garage door, to remain unfilled not only allows cold air and moisture into your home, but in some cases, it allows unwanted outdoor pests to make their way inside. The first thing you should do is take inventory. Find out where you have gaps around your exterior doors and assess how large they are. If you have double front entry doors, be sure to also pay attention to the gap between the doors.4. Install Weatherstripping
Weather strip is one of your most important and effective weapons against cold air and moisture throughout the winter. It’s easy to install, and doesn’t require any specialized tools, so even a beginner can tackle it in just a few easy steps. In most cases, you can apply weather stripping without removing your door from the door frame. It’s likely that you can find several different kinds of weather stripping material at any well-stocked home improvement store. You might choose wrapped foam, metal flange, vinyl, or silicone bulb.5. Use a Door Snake
Door snakes are highly effective ways of blocking out air leaks from doors and windows. These weighted fabric tubes offer extra insulation that can block out any unwanted chill or moisture. You can buy door snakes already made, or you can make your own.6. Re-caulk Your Doors (And Maybe Your Windows Too)
Over time, the caulking around your doors and windows can degrade and lose its effectiveness. It’s a good idea, every fall before the temperature really drops, to invest in a couple of tubes of caulk so you can refresh the seal around your exterior doors. Even if you only refresh areas where air leaks are getting through, it’s likely to make a big difference.4 Benefits of Sealing Doors for Winter
Sealing your exterior doors for winter takes a little bit of work, but it also brings a wide variety of benefits, including:1. Temperature control
Cold air leaks make interior rooms uncomfortable during the winter, and make it difficult for heating system to keep the temperature at a consistent and comfortable level. The same is true in the summer—when gaps around doors and windows let precious, air-conditioned air escape and hot, humid outdoor air take its place.2. Energy savings
The harder your heating system has to work to keep the temperature modulated, the more money you’re spending on energy. Not only is cold air getting in through gaps around doors and windows, but the inverse is that your nice, cozy warm air also is escaping through those same gaps. Making sure every door and window is securely sealed can make a huge difference on utility bills over the winter. By some estimates, energy costs related to heat loss can be reduced by as much as 15 to 18 percent by properly sealing and insulating around your external doors.3. Keeping Out Unwanted Pests
It’s an ugly truth that if gaps are large enough for cold air to pass through, they are also large enough for unwanted pests to make their way inside your home. After all, they’re want to stay warm, too!4. Improved Air Quality
it may seem intuitive that allowing a few gaps here and there allows for natural ventilation, but this approach generally isn’t recommended by energy experts. One key reason for this is that gaps not only allow cold air, but also dust, dirt, and outdoor allergens, which degrades your internal air quality. Sealing your home against unwanted outdoor debris can ensure that you, your family, and guests enjoy the highest quality indoor air possible.Sealing Doors for Winter is an Easy, Cost-Effective DIY Project
