8 Easy Steps on How to Trim Around Bifold Doors
Step 1: Measure and Mark
Start by measuring the height and width of your bifold doors using your measuring tape. Accurate measurements are crucial for a clean finish, so take your time and double-check your numbers. Make sure to account for the trim width on both sides of the door. Once you have your measurements, use your pencil to mark where you will place your trim on the wall. Use your level to ensure your lines are straight.
Step 2: Cut the Trim to Size

Utilizing the measurements you painstakingly took in the previous step, cut the trim to the appropriate size using your handsaw or circular saw. Remember to use safety gear and take necessary precautions while handling saws. When cutting the edge, cutting slightly larger than your measurements is a good idea.
You can always trim it down more if needed, but you can only add length back if you cut it short. Once your trim pieces are cut, double-check that they fit around your bifold doors as expected.
Step 3: Attach the Trim
Begin by placing your pre-cut trim pieces against your marked lines around the bifold door. Once you’ve verified that they fit correctly, fasten them to the wall using your finishing nails or trim screws and a hammer or drill. Start from the top and work your way down, ensuring the trim is straight and flush against the wall.
For a cleaner finish, make sure the nails or screws are slightly recessed into the trim. If you find gaps between the frame and the wall, you can use a putty knife and wood filler to smooth out these areas. Once you’ve attached all the trim pieces, admire your handiwork. Your bifold doors are now beautifully framed!
Step 4: Fill and Sand
Once your trim is securely attached around the bi-fold doors, the next step is to fill in any nail or screw holes with wood filler. Use a putty knife to spread the stuffing smoothly over these areas. Allow the filler to dry according to the manufacturer’s instructions — typically a few hours. After completely drying the filler, take a piece of fine-grit sandpaper and gently sand over the filled areas until they are smooth and flush with the rest of the trim. This will give your trim a seamless finish when painted.
Step 5: Paint or Stain

The next step in trimming around your bifold doors is painting or staining your trim. Choose a paint or stain that matches the rest of your interior for a harmonious look, or opt for a contrasting color to make your doors stand out. Before painting or staining, tape off the surrounding areas to protect them from accidental spills or splatters. Use a small brush for precise application, and remember to follow the wood grain for the best results.
Apply multiple thin layers, allowing each layer to dry completely before applying the next. Once the final layer has dried, carefully remove the tape. Your bifold doors now have a professionally trimmed appearance that adds elegance to your space.
Step 6: Finishing Touches
The final phase in trimming your bifold doors involves inspecting your work, making minor adjustments, and cleaning up. Examine the trim closely for any uneven spots, drips, or missed areas, and touch up with the paint or stain as needed. Once everything looks perfect, clean up your working area. Remember to clean your tools and brushes for future use.
Finally, take a step back and take in the sight of your newly trimmed bifold doors. Pat yourself on the back for a job well done. That’s it! With these easy steps, you’ve successfully achieved a professional-looking finish that enhances the aesthetic appeal of your space.
Step 7: Maintenance
The final step centers around keeping your beautifully trimmed bifold doors in shape. Regular maintenance is vital to preserving the door’s professional finish. Lightly dust the trim occasionally to prevent buildup, and clean it with a damp cloth if necessary.

Avoid using harsh chemicals that could damage the paint or stain. For painted trim, promptly touch up any scratches or chips to prevent them from becoming more noticeable. With these simple maintenance steps, your bifold doors will continue to add an elegant touch to your space for years to come.
Step 8: Enjoy Your Space
Now that you’ve successfully trimmed your bifold doors, it’s time to enjoy the fruits of your labor. Your newly enhanced doors should add a touch of sophistication and elegance to your space, elevating its overall visual appeal. Whether it’s a welcoming entryway, a cozy bedroom, or a stylish closet, your bifold doors can now stand proudly as a testament to your carpentry skills.
Remember, home improvements like these not only make your living space more pleasing to the eye but can also boost the value of your property. So, revel in your accomplishment and enjoy your refreshed space!
By following these ten easy steps, you have learned how to trim around your bifold doors like a pro. With just a few tools and materials, you can transform your plain doors into stylish features that enhance the overall look of your space.
5 Additional Tips and Tricks
- Measure Twice, Cut Once: Always measure the dimensions of the bifold doors and the trim before cutting. This will ensure a clean, precise fit and prevent any wastage of materials.
- Choose the Right Trim: The trim style should match your room’s overall aesthetic. Whether you prefer something modern or traditional, a variety of options are available in the market.
- Use Quality Equipment: To get a professional finish when trimming around bifold doors, it’s essential to use quality cutting tools. A sharp, sturdy miter saw can provide neat, precise cuts.
- Secure the Trim Properly: Ensure the trim is securely fixed to the wall. Use nails or adhesive for smaller, lightweight pieces, but consider using screws for larger, heavier ones.
- Keep a Level Handy: Always use a level to check your trim is straight and even. This will give your doors a polished, professional look.

With these additional tips and tricks, you can successfully trim around your bi-fold doors and achieve a seamless, finished look in your space.
5 Things You Should Avoid

- Neglecting the Prep Work: Remember to complete the essential step of preparing the area around the doors. This includes cleaning, sanding, and priming the surface where the trim will be applied.
- Ignoring Safety Measures: Safety should always be a priority when working with tools. Always wear protective gear such as safety glasses and gloves, and ensure your work area is well lit and free of any potential hazards.
- Forgetting to Account for Door Swing: When trimming around bifold doors, it’s crucial to remember that the doors will need room to swing open and shut. Ensure the trim doesn’t impede this functionality.
- Disregarding the Door Material: Different door materials may require different trim types or fasteners. Make sure you choose materials that are compatible with your bifold doors.
By avoiding these common mistakes, you’ll be able to achieve a flawless trim job around your bi-fold doors and enhance the overall look of your space.
