So keep reading if you’re ready to get started transforming your old windows into properly insulated energy efficient ones!
Why Do You Need to Cap a Window?
Window capping is a relatively simple process that essentially seals the gap between the window frame and the wall. Without this seal, warm or cool air can escape, leading to an inefficient home energy system and higher utility costs. In addition to improving insulation, capping your windows also helps in keeping pests out of your home.
Materials Needed
Before you get started capping your windows, it’s important to make sure you have all of the necessary materials. The most essential item is a window cap, which covers the frame and wall gap. You’ll also need exterior foam tape or strips to seal the edges of the window. Finally, be sure to have caulking on hand for any additional sealing requirements.
11 Step-by-step Guides on How to Cap a Window
Step 1: Preparing the Window
Start by removing any old capping material if necessary. Use a putty knife and scraper to remove the existing capping and clean the window frame. Make sure you check that the space between the frame and wall is not obstructed, as this will affect how easily you can cap the window.
The wall gap should also be clean and dry so that the new capping material can properly adhere. If you find any cracks or other damage, patch them with a sealant before continuing. This will ensure that your capping job is secure and efficient.
Step 2: Measure for Size
When measuring the size of your window cap, it’s important to consider both the width and height of your window frame. Take measurements from each corner to ensure an accurate fit. Keep in mind that a cap should overlap the frame and cover any gaps with at least 1/2 inch on all sides.
When selecting a window cap, look for one that is made of vinyl since it will be more durable and better able to weather the elements. But make sure that the cap matches your home’s exterior design. It’s also a good idea to get your window capping material from the same manufacturer as it will ensure that all of the components are compatible.
Step 3: Cut Out Pieces for Capping
Using a utility knife or saw, carefully cut out pieces of capping material according to your measurements. Be sure to leave extra length on all sides so that there is enough material to cover the gap. It’s also important to make sure that the pieces fit together properly, as this will allow for a better seal.
Although it’s possible to install the window capping yourself, you may want to consider hiring a professional if you don’t feel confident in your abilities. It’s a good idea to get the job done right the first time since any mistakes will be obvious and difficult to fix.
Step 4: Attach Foam Tape or Strips
Attach a foam tape or strip along the edge of the window frame where you will be applying capping material. This will help in keeping air from entering your home through any gaps in the capping.
But be sure to use the tape or strips that are designed for outdoor use, as they will be better able to withstand harsh weather conditions. If you’re using foam strips, cut them to the exact size needed. This will ensure that the capping material is sealed securely. Otherwise, you can use a larger strip and then trim it down to size once the capping material is in place.
Step 5: Apply Capping and Secure it in Place
Line up your window cap with the edges of the window frame and press it gently into place, making sure that all sides are overlapping equally. Use finishing nails to secure them further by driving them through predrilled holes in each corner.
If your window cap is vinyl, use an air stapler instead of nails. It will help provide a better seal and prevent any air leakage. But be sure to use an air pressure that is not too strong, as it can damage the capping material. It’s also important to make sure that all of the pieces are aligned properly, as this will help in creating an even seal.
Step 6: Cut Away Excess Material and Caulk Edges
Once you’re done securing your window cap, you can trim away any excess material using a utility knife. Then apply caulking to the edges of the window frame and capping to create an airtight seal. It’s important to use good quality caulking that is designed for outdoor use, as this will ensure that it can withstand the elements. Wait until the capping is completely dry before applying caulking.
Step 7: Smooth Out Caulk and Allow Time for Drying
Smooth out the caulking with your finger or a damp cloth, then use painter’s tape to hold it in place until it is completely dry. This will usually take about 24 hours before you can remove the tape. But make sure that you don’t move the window frame while it is drying, as this can cause the capping material to come loose.
If you do, you’ll have to wait for the window cap and caulking to dry before applying new material. Remember to let the caulking dry completely before attempting to open or close the window.
Step 8: Paint Your Window Caps (Optional)
If desired, you can paint your window caps for an extra touch of style. Make sure that all areas are fully covered and dried before applying another coat of paint if necessary. It’s important to use paint that is designed for outdoor use, as this will help it stand up better against the elements.
But be sure to wait until the capping is completely dry before you start painting. It’s also a good idea to use a primer before painting, as this will help the color last longer. It’s best to paint your window caps in a warm, dry environment.
Step 9: Put On Your Window Screens and Trim
Put your window screens and any other trim back in place, as these will help with airflow and provide extra insulation. This will also help protect your home from any bugs or other pests that may try to enter.
Make sure to securely attach all screens and trim, as this will help to ensure that your windows are properly sealed. If you need to replace any screens, use ones made of stainless steel or other durable materials that will last longer in outdoor conditions. It’s also important to clean and inspect your window screens before putting them back in place.
Step 10: Test the Capping for Leaks
To make sure that there are no air leaks around the capping, you can close your windows and light a candle near the gap to detect any drafts. If a draft is found, use caulking or foam tape to seal it up. This will help to keep your home properly insulated and reduce energy costs.
It’s also a good idea to check the capping on a regular basis to make sure that it is still secure and airtight. If you find any problems, don’t hesitate to contact a professional for help. Those are the steps to cap a window. With careful attention to detail, you can ensure that your windows will be properly sealed and protected from any weather or pests.
