How to Measure for a Storm Door to Get the Best Possible Fit


So, it’s time to measure for your new storm door? Well congratulations to you, a storm door can be an amazing upgrade to your home, providing not only an extra layer of security, but also adding in a whole new level of energy efficiency. There is a reason storm doors haven’t gone out of style, so if you feel it’s time for you to get your own storm door, we’re here to back you up by teaching you all about storm door measurements.

When you’re ready to measure for a storm door, it may seem easy at first. But, getting the measurements right for different door openings is crucial for a good fit.

You need to measure the width and height in three places: the top, middle, and bottom for width, and the left and right sides for height. Taking these three measurements ensures you record the narrowest dimension for width and the shortest dimension for height.

What if the measurements don’t match? Next, we’ll look at how small differences can affect your door’s installation and performance, and we’ll help you deal with any measurement differences you find.

Key Takeaways

  • Check the opening width by measuring the door frame at the top, middle, and bottom. Use the smallest width.
  • Measure how tall the door frame is on the left and right sides. Choose the shortest height.
  • To make sure the frame is square, measure from one corner to the opposite corner diagonally. Both measurements should be the same.
  • Measure how deep the door frame is to make sure the storm door will fit.
  • Look at the storm door maker’s guide for the smallest and largest sizes that will work. Choose a storm door size that fits these limits.

Storm Door Basics


A storm door is an extra door outside your main front door. It helps protect your home from bad weather and makes it safer. It’s like having a helpful guard that keeps out cold air and makes your house look nicer.

These doors are usually made from strong materials like aluminum, wood, or vinyl, which help protect your main door and also help keep your house warm, similar to wearing an extra sweater. Storm doors can also bring in more natural light.

Storm doors often come with special panels that can be glass or a screen, so you can let in light and fresh air when the weather is good. Adding a storm door is a smart choice that keeps your home safe and looking good.

Essential Measurement Techniques: Three Measurements


To make sure your new storm door fits well, you need to measure your door frame correctly. It is crucial to take accurate measurements of your existing storm door for replacement. Here’s how you can do it with a tape measure:

  1. Measure the Width: Check the width inside your door frame at the top, middle, and bottom. Write down the smallest number you get. Remember to identify the difference between the door frame and the exterior trim.
  2. Measure the Height: Now, measure the inside height at both the left and right sides. Use the smallest number here too.
  3. Check for Square: Measure from the top left corner to the bottom right corner and from the top right corner to the bottom left corner. If these two numbers are different, your frame mightn’t be perfectly square.
  4. Depth of the Door Frame: Lastly, measure how deep the door jamb is to ensure the replacement storm door will shut right.

Follow these steps to pick the correct size storm door! Be aware of the standard storm door sizes available in the market to ensure a proper fit.

Tools Required for Measurement


Before you start measuring for your new storm door, make sure you have these tools: a tape measure, a level, and a notepad to write down your measurements.

Use the tape measure to find out the width and height of your door frame. Make sure to measure in different spots to ensure the measurements are correct.

The level will help you check that the surface you’re measuring is flat and even. This is important for the door to fit properly.

Always write your measurements in the notepad so you don’t forget them.

With these tools, you’re ready to start the job right.

Correcting Uneven Frame Issues


If you notice that your door frame isn’t straight, you can use shims to fix it before installing a storm door. You may need to adjust the existing opening with shims to ensure a proper fit. Follow these simple steps:

  1. Check if it’s Straight: Use a level tool to see where the frame isn’t straight. The top or bottom might be tilted.
  2. Put in Shims: Place shims in the gaps on the side of the frame with the hinges until the frame is straight. Use the appropriate shim thickness to reduce the opening to the required size. Cut off any extra shim sticking out.
  3. Hold the Shims in Place: When the frame is straight, use screws to keep the shims from moving.
  4. Double-check: Make sure everything is still straight after you secure the shims. You might need to make some adjustments.

Understanding Manufacturer Specifications


After fixing uneven frame issues with shims, check the manufacturer’s specifications to make sure your storm door fits well. Different brands might have different rules, so it’s important to look at these before buying your door. Ensure you have a 1-in. wide x 1-in. deep mounting surface for proper fitting.

You can find this information in the product manual or on the manufacturer’s website. Be sure to note the smallest and largest sizes allowed for the door’s width and height, as these can change.

Also, check for any specific needs regarding the door’s thickness and where to place the hardware. Following these guidelines closely will help ensure that your storm door fits properly, works well, and looks good.

Don’t miss this step—it’s crucial for a good installation!

Estimating Installation Costs


When you plan to install a storm door, you need to think about the costs for materials, labor, tools, and any unexpected expenses. Here is an easy way to figure out your budget:

  1. Material Costs: The price of the door itself can be from $185 to $650, depending on what it’s made of and its features.
  2. Labor Costs: If you hire someone to install the door, it could cost you an extra $75 to $400.
  3. Tools and Supplies: If you decide to install the door yourself, you might need to buy some tools, which could cost between $50 and $100.
  4. Unexpected Expenses: It’s a good idea to keep some money aside, about 10% more than your total estimated costs, just in case you run into any surprises.

Plan well and you can keep your spending under control!

Maintenance Tips for Longevity

Regular care makes your storm door last longer and work better. Keep it clean by washing it with soap and water every few months.

Always check for any breaks or damage and fix them quickly to keep it working well. Also, put oil on the hinges and locks often. This stops any squeaks and helps your door open and close smoothly.

Choosing the Right Storm Door


When picking new storm doors, it’s important to consider factors such as how long they will last, their appearance, and how well they complement your house’s style. Here’s an easy guide to help you choose:

  1. Material: Go for aluminum if you need something strong, wood for a traditional style, or vinyl for easy care.
  2. Design and Features: Choose doors with a full glass panel for more sunlight, or doors that allow air in if you want better airflow.
  3. Saving Energy: Look for doors with insulated glass or good seals to help reduce your energy bills.
  4. Color and Finish: Choose a color that looks good with the outside of your house to make it more appealing.
