Installing a porthole front door is a great way to add a unique and stylish touch to your home’s entrance. While the process may seem daunting, it can be completed with just a few tools and some basic DIY skills. Here are the steps to follow:

Measure the space:

Start by measuring the width and height of the opening where the porthole door will be installed. This will ensure that you purchase a door that fits perfectly.

Purchase the door:

Choose a porthole door that complements the style of your home and fits the measurements you took. You can find porthole doors at home improvement stores or online.

Prepare the opening:

Remove any existing door and hardware from the opening. Clean the area thoroughly to ensure a smooth and even surface for installation. If necessary, repair any damage or rot to the surrounding frame.

Install the hinges:

Position the door in the opening and mark where the hinges will be attached. Pre-drill pilot holes for the screws, then attach the hinges to the door and the frame.

Attach the door handle:

Install the door handle and lock according to the manufacturer’s instructions.

Install the porthole:

Position the porthole on the door where you want it to be located. Mark the outline of the porthole with a pencil, then use a hole saw to cut out the opening. Be sure to wear eye and ear protection when using power tools.

Install the porthole frame:

Place the porthole frame around the opening and attach it to the door with screws. Use a sealant to fill any gaps between the frame and the door to prevent drafts and water infiltration.

Install the glass:

Insert the glass into the porthole frame and secure it in place with glazing points. Apply a small bead of sealant around the edges of the glass to provide additional protection against the elements.

Test the door:

Open and close the door to make sure it operates smoothly and the porthole is securely attached.

Finish the installation:

Apply paint or stain to the door and frame as desired to match your home’s décor.
