Why Installing an Exterior Door Matters

A well-installed exterior door is essential not just for aesthetics but also for functionality.

  • Screws and anchors 
  • Level and measuring tape 
  • Pry bar and hammer 
  • Caulk gun and waterproof sealant 
  • Drill and screwdrivers 
  • Shims 
  • Insulation foam 

Step-by-Step Guide: How to Install an Exterior Door

Step 1: Remove the Old Door

Begin by removing the existing door, including its hinges and frame. Use a screwdriver or drill to take the door off its hinges, and a pry bar to gently remove the old frame and trim. Ensure you clean the rough opening thoroughly before proceeding.

Step 2: Measure the Rough Opening

Measure the width and height of your rough opening to make sure the new door will fit correctly. A prehung exterior door is typically easier to install and includes the frame, which simplifies alignment.

Step 3: Dry Fit the New Door

Place the exterior door into the rough opening to test the fit. Use shims on both sides to center the frame and ensure it’s level and plumb. Make any necessary adjustments to the opening before securing the door.

Step 4: Apply Flashing and Waterproofing

Add flashing tape around the rough opening to prevent water infiltration. Apply waterproof sealant along the edges to further protect against moisture, especially in the case of wooden double doors exterior and solid wood doors exterior.

Step 5: Install the Door Frame

With the door removed temporarily, apply a generous bead of caulk along the sill area. Carefully insert the door frame into the opening and start screwing it in through the hinge side first. Use a level throughout this step to maintain accuracy. Shims help keep the door square during fastening.

Choosing the Right Exterior Door Style

When picking a new door, you have many options beyond just functionality:

  • Exterior front double doors: These are great for large entryways and give a grand entrance look. 
  • Wooden double doors exterior: Timeless and durable, but require regular maintenance. 
  • Solid wood doors exterior: Provide superior insulation and a premium look. 
  • Exterior double front doors with glass: Offer elegance and allow natural light into the foyer. 

These styles not only change the look of your entrance but can also increase your home’s market value.

Step 6: Secure the Door and Check Alignment

Reinsert the door and test its swing. It should open and close smoothly without scraping or binding. Once satisfied, secure all screws, adjust shims if necessary, and insulate any gaps between the frame and the wall with expanding foam.

Step 7: Attach Trim and Seal

Install exterior and interior trim to cover the gaps. Use caulk along the edges for a watertight seal. A well-sealed door prevents drafts and water damage, especially important for exterior front wood doors and double entry doors with glass.
