Despite all these, some homeowners would like to have the option of installing a storm door because of its protective advantages or for adding flair to their front doors.

Protection from Elements

Depending on where you live, the climate can go from blazing hot summers to freezing cold winters. While fiberglass doors are weatherproof and can withstand these elements, having a storm door can lessen the wear and tear that your normally exposed front door will experience, making it look new and fresh for years to come.

Energy Efficiency

Storm doors provide tight seals around your entryway when closed. This gives your home an added layer of insulation during harsh winters because it can help keep the thermostat lower. 

During nicer weather, you can reduce energy use by keeping your fiberglass doors open and your storm doors closed because it’s a great way to let the light in. 

Enhanced Appearance

There are many models of storm doors available on the market and some of them provide an extra flair to your home’s design. If your current front door is looking a little bit too plain and you’d like to amp up the look a little bit, a storm door can do this for you.

It will make your entryway look more attractive and new, with the added protection a storm door can provide. Storm doors can be a valuable addition to your home. You can have them installed by a contractor, or do it by yourself.

Do you think it is absolutely necessary for you to have one for your home? We will be answering these through the following questions.

Can a storm door be installed on any door?

Technically, a storm door can be installed on any door that you may have. However, some homes might not need a storm door. There are many different factors that can affect your need to have one installed.

Homes located in places with ideal climates do not need a storm door as a good, quality front door is already enough. There are also homes wherein there is not enough space for a storm door to be installed.

If your front door is already sitting right on the very edge of the door jamb, it will make installation practically impossible. 

Can you replace a storm door without replacing the frame?

Since door frames are less prone to the daily stresses doors are subjected to, they are a lot sturdier and last longer than the door itself. If your storm door is due to be changed, you can have it replaced without having to change the current frame.

If you find yourself needing to replace your storm door, there are a few things you have to check:

  1. Make sure that your door frame is in excellent shape. It should not be warped or too worn out as your new door might not fit properly.
  2. Inspect if your current door is closing properly. Check for gaps around your storm door that you need to have insulated.
  3. Remember to correctly measure your existing door before getting a replacement. This will ensure that your new storm door will fit with your existing frame without any issues.

How much does a storm door cost?

The more basic aluminum types usually start off at around $100 to $200 apiece. For storm doors that provide added features, the cost starts at around $500 and can go higher.

Aside from the cost of your door, another thing that you have to consider is how you’ll be having it installed.
