How to Fit a Composite Door Frame 

Tools and Materials Needed: 

  • Composite door frame 
  • Composite door 
  • Level (4-foot level recommended) 
  • Tape measure 
  • Screwdriver or drill 
  • Screws (usually provided with the frame, 3-inch screws recommended) 
  • Shims (wood or plastic) 
  • Caulk or spray foam insulation 
  • Wood filler (for any visible screw holes) 

Step-by-Step Process: 

Preparation: 

Remove the Old Frame: If replacing an existing door frame, carefully take it out using a pry bar and hammer. Ensure the opening is clean and free of debris. 

Inspect the Door Opening: Measure the width and height of the door frame opening. A typical door frame should be approximately 2 inches wider and 2 inches taller than the door itself to allow for shimming and adjustments. 

Dry Fit the Frame: 

Place the Frame in the Opening: Set the composite door frame in the opening to check the fit. Ideally, the frame should have about 1/8 inch gap on each side for shimming. 

Use Shims: Insert shims at the hinge side first. You may need to use 1 to 3 shims depending on the wall’s straightness. Ensure the frame is positioned about 1/4 inch back from the front of the wall for proper door sealing. 

Check for Level and Square: 

Use a Level: Place a 4-foot level on the top and sides of the frame to check for level and plumb. Adjust with shims until the frame is level. The top of the frame should be level, and both vertical sides should be plumb. 

Measure Diagonally: Check for square by measuring diagonally from corner to corner. The measurements should be equal; if they are not, adjust the shims accordingly. 

Secure the Frame: 

Drill Pilot Holes: Using a drill, make pilot holes through the frame into the wall studs. Space the screws approximately 12 to 16 inches apart along the vertical edges and at least 4 inches from the top and bottom of the frame. 

Screw the Frame in Place: Use 3-inch screws to secure the frame. Start with the top screw, then the bottom, and finally, the side screws. Ensure not to overtighten, as this could warp the frame. 

Final Adjustments: 

Recheck Level and Square: After securing, use the level again to confirm that the frame remains level and square. Make any final adjustments using shims if necessary. 

Seal Gaps: Fill any gaps between the frame and the wall with caulk or spray foam insulation to improve energy efficiency. Use expanding foam sparingly, as it can push the frame out of alignment. 

Install the Door: 

Attach the Door to the Frame: Align the hinges on the door with the pre-drilled holes in the frame. Secure the hinges with the provided screws. 

Test the Door: Open and close the door to ensure it swings freely without binding. Adjust the hinges if necessary. 

Finishing Touches: 

Fill Screw Holes: Use wood filler to fill any visible screw holes on the frame for a neat finish. Once dry, sand the area smoothly. 

Install Weather Stripping: Consider adding weather stripping around the door to enhance insulation and prevent drafts. 

Do Composite Doors Required Special Frame?

Yes composite doors don’t strictly require special frames. They can be installed in various frame styles, including chamfered and sculptured profiles. However, choosing a compatible frame that provides adequate support and security is important.

While it’s possible to use an existing wooden frame, it’s generally recommended to install a new frame specifically designed for composite doors. This ensures optimal performance, security, and energy efficiency.

What Should be the Gap Between Composite Door and Frame?

The ideal gap between a composite door and its frame should be between 3mm and 5mm. This gap is important for ensuring proper door function, weatherproofing, and security. 

A gap that’s too small can lead to the door binding and not closing properly, while a gap that’s too large can compromise insulation and security.

Can we fit a Composite door on a Wooden Frame?

Yes, you can fit a composite door into a wooden frame. However, it’s important to note that this is not the ideal solution and comes with certain limitations. Because wooden frames may not provide the same level of security as a dedicated composite door frame. Also, wooden frames may not seal as tightly as composite frames, leading to potential drafts and water ingress.  And it may be challenging to achieve a perfect fit and ensure proper alignment of the door and frame.

How Long Does it take to Fit a Composite Door?

Typically, it takes between 1.5 to 3 hours for a professional to install a composite door. This includes removing the old door, installing the new door and frame, and ensuring everything is properly sealed and secure.

What is the Cost of the Composite door Installation in Ireland?

The cost of installing a composite door typically ranges from €400 to €800. This price generally includes the removal of the old door, preparation of the frame, and installation of the new composite door.  if you want to know the accurate installation price then you can directly call us or fill out a contact form today!

Additional customization options, such as adding sidelights, upgrading hardware, or installing custom locks, can increase the overall installation cost. For example, adding sidelights can cost between €450 and €900 per side, while upgrading hardware like handles and letterboxes can range from €50 to €150 each.

Can you fit a new Composite Door into an Existing Frame?

Yes, you can fit a new composite door into an existing frame, but it’s not always the best option. Because a dedicated frame is designed to work seamlessly with the composite door, providing a better fit and superior weatherproofing.
