Before you start installing an exterior door, it’s important to gather all the tools and materials you’ll need. Being well-prepared will make the installation process smoother and more precise. Here’s what you’ll need:


  • Pre-hung exterior door: This includes the door itself and the frame that supports it.

  • Chisel: To make fine adjustments to wood or framing.
  • Pliers: For gripping and pulling out nails or other small hardware.
  • Spackle: To fill in any holes or imperfections in the surrounding wall.
  • Putty knife: Useful for spreading spackle or caulk.
  • Drill/Driver & bits: Essential for drilling pilot holes and driving screws.
  • Circular saw: To cut any materials to fit, such as trimming the door jamb if necessary.
  • Router (optional): For more advanced carpentry tasks, like creating a recess for hinges.
  • Screwdriver set: For working with various screws during the installation process.
  • Hinges, locks, knob: These are the hardware components that will make your door functional.

Step 2: Preparing for Installation


Before you can install your new exterior door, there are some important steps you need to take to get the area ready. Here’s what you should do:


  1. Measure and Plan:


  • Measure the height, width, and jamb width of your current door frame. These measurements will help you choose a pre-hung door that fits perfectly.
  • Write down these dimensions so you don’t forget them.
  • While you’re shopping for your new door, think about any design features you might want, like colors that match your home’s style.


  1. Remove the Old Door:


  • Start by taking off the hinges. You might need a screwdriver or drill to unscrew them from the door frame.
  • Once the hinges are loose, carefully lift the door off its hinges and set it aside.
  • Use a pry bar to gently remove any trim or molding around the door.
  • Make sure to get rid of any nails or screws that were holding the old frame in place.

Now that you’ve finished preparing the area, it’s time to move on to the next step: installing your pre-hung exterior door.


Step 3: Installing a Pre-hung Exterior Door


Installing a pre-hung exterior door involves a series of critical steps to ensure a secure and proper fit that enhances your home’s energy efficiency and curb appeal. With the old door removed, you can now focus on installing your new pre-hung door.


Test-Fitting a Pre-Hung Door


Before proceeding with the installation, it is vital to test-fit the new door in the rough opening. This step verifies that the door will fit without any issues:


  • Carefully place the pre-hung door into the opening.
  • Check for any gaps or unevenness.
  • Ensure there is enough room for shimming and squaring the frame.
  • Note areas that may need adjustment during the actual installation.


Preparing the Opening for Installation


Preparing the opening correctly is crucial for a seamless installation:


  • Clean the subfloor where the sill will rest, ensuring it’s level and free of debris.
  • If you encounter an uneven surface, use shims to create a level base.
  • Apply silicone caulk along the bottom of the rough opening where the sill will sit, providing additional sealing against moisture.


Installing a Pre-Hung Door Frame


With preparation complete, it’s time to install the frame:


  • Center the pre-hung door in the opening, flush with the exterior wall.
  • Temporarily secure it by nailing through one of the upper corners of the frame.
  • Ensure that it swings open and closed smoothly without dragging on any surfaces.


Securing a Pre-Hung Door Frame in Place


Once positioned correctly, securing your pre-hung door frame is next:


  • Check that hinge-side jamb is plumb using a level.
  • Shim behind hinges if necessary to achieve straightness.
  • Replace two screws in each hinge with long anchor screws provided for added strength.


Attaching Moulding to a Pre-Hung Door Frame


Moulding adds both aesthetic and functional value by covering gaps and enhancing insulation:


  • Measure and mark where moulding will attach around the door frame.
  • Trim any excess siding if necessary to accommodate moulding.
  • Nail moulding into place using galvanized nails every 12 inches.


Adjusting the Threshold


A properly adjusted threshold ensures a tight seal at the bottom of your door:


  • Check manufacturer instructions for specific guidance on adjusting your model’s threshold.
  • Use a screwdriver or wrench to raise or lower the threshold until there is no visible gap when the door is closed.
  • Ensure weather stripping compresses slightly against the door for an effective seal.


By carefully executing each step when installing a pre-hung exterior door, you set yourself up for success. Proper installation leads to improved energy efficiency and security. For those looking into further home improvements, whether replacing old fixtures or embarking on new construction projects, products like new construction windows offer seamless integration with expert installation services.

Step 4: Installing Door Hardware

After securing the door in place, installing a doorknob and lockset on an exterior door is the next critical step. This hardware is not just about aesthetics; it’s crucial for security and functionality.


Doorknob and Lockset Installation


  • Start by inserting the latch assembly into the side hole of the door. Ensure that the curved side of the latch faces the direction in which the door closes.
  • Slide the lockset tailpieces through the latch bolt.
  • Align the exterior part of the knob with its interior counterpart, ensuring that both tailpieces slide into their respective slots.
  • Tighten both parts together with a screwdriver. Avoid over-tightening which can impede smooth operation.
  • Test the doorknob by turning it back and forth to check for smooth operation.


Installing Trim and Casing


If you had to remove trim or casing during Step 2, now is the time to replace or install new ones:


  • Measure and cut the new trim to fit if necessary, taking into account any irregularities in the wall surface.
  • Securely nail or screw in the trim around your door frame.
  • For a professional finish, fill any nail holes with wood filler and caulk any gaps between your trim and both your wall and door jamb.


Remember to insulate around the entire frame if you haven’t already. Weatherproofing your exterior door ensures energy efficiency and contributes to home security.


Finally, attach the strike plate to the jamb aligning it with the latch bolt. Screwing it securely ensures that when your door closes, it latches properly without any resistance.
