Replacing an Existing Door

Changing an existing door can be an easy way to update the look of your home, as well as improve its security and energy efficiency. Whether you're looking to replace an old or damaged door, or simply want to update the style, the process of changing a door is relatively straightforward in theory but can be proven difficult without any experience. In this guide, we'll take you through the steps of changing an existing door, from measuring and ordering the new door to installing it.

Step 1: Measure the Existing Door

The first step in changing an existing door is to measure the existing door. This will ensure that you order the correct size and style of door. Measure the width and height of the door, as well as the thickness of the door.

Step 2: Select the New Door

Once you have the measurements of the existing door, it's time to select the new door. Consider the style of the door, as well as the materials it is made from. Take into account whether the door will be exposed to the elements or if its purely an internal door. You'll also need to decide whether you want a pre-hung door or a slab door. A pre-hung door comes with the frame already attached, while a slab door is just the door panel itself.

Step 3: Order the New Door

Once you've selected the new door, it's time to order it. Be sure to provide the door manufacturer with the measurements you took in Step 1, as well as any other specifications, such as the type of hinge or lock you want.

Step 4: Remove the Old Door

Before installing the new door, you'll need to remove the old door. Carefully remove the door, being careful not to damage the door jamb or surrounding walls.

Step 5: Install the New Door

With the old door removed, it's time to install the new door. If you've chosen a pre-hung door, the frame will already be attached to the door. If you've chosen a slab door, you'll need to attach the hinges and lock to the door before installing it. Millimeters mean everything in this instance and miss measuring can cause doors to close out of plumb, level, or not even close at all. Carefully position the new door in the door jamb, making sure it is level and plumb by looking at the gap between the door the and door frame. This is called the reveal and it important to have an spacing of 2-4mm around the door. Secure the new door in place using the hinges and lock.

Step 6: Finish the New Door

Finally, you can finish the new door by adding any trim or casing, as well as painting or staining the door. This will help protect the door from the elements and give it a finished look. Painting a door is not like painting a wall and could be the deciding factor in the appeal of the door. Painting with a quality enamel or water based enamel paint, and in conjunction with a small nap or foam roller is adequate enough for most doors. For premium results use a paint conditioner such as ‘Floetrol’ to smooth out brush strokes and roller stipple.

Conclusion

Changing an existing door is a relatively simple process that can be completed by most DIY enthusiasts. With the right measurements, materials, and tools, you can easily update the look of your home and improve its security and energy efficiency.
