Step-by-Step Guide: How to Replace a Door Frame

Replace a door frame isn’t as hard as it seems. Let’s break it down simply, step-by-step, so you can handle it confidently.

Step 1: Remove Your Old Door from the Hinges

Open your door fully. Gently remove the hinge pins using a screwdriver or hammer, then carefully lift the door away. Set it safely aside.

Step 2: Carefully Remove the Trim and Molding

Use a pry bar to gently loosen and remove the trim around the door frame. Take your time to avoid accidentally damaging your drywall or paint.

Step 3: Completely Remove Your Old Door Frame

Use your saw or pry bar to carefully cut through any nails holding the frame in place. Remove each piece slowly to protect your walls from accidental damage.

Step 4: Prepare Your Doorway for the New Frame

Remove any debris, dust, or old caulk. Make sure all surfaces are smooth, even, and ready for the new frame.

Step 5: Install and Align Your New Door Frame

Carefully place your new frame into position. Check its alignment thoroughly using your level. This is important.

• If the doorway isn’t perfectly even, use small wooden shims to adjust the frame.
• Once everything looks straight, secure it firmly using galvanized screws (highly recommended for exterior doors).

Step 6: Add the Finishing Touches

Now, it’s time to install the trim and molding around your new frame. Make sure to seal the edges with caulk to keep out drafts and moisture. Finally, give it a fresh coat of paint or stain to match your home’s décor and add a beautiful finishing touch!

Tip: Always double-check alignment before finishing your door installation to ensure your door opens and closes smoothly.
