Are you looking to save money by installing or hanging an interior door yourself? Or maybe you need to replace a door. Installing an interior door is an easy way to upgrade the look of your home. In this tutorial we’ll show how to correctly install a door and hardware, and build the frame. This is a totally doable home improvement project. You can save money by making the door frame and installing the door yourself.
Materials and tools used:
- Door (duh)
- Door jamb kit – top and sides
- Straight edge
- Tape measure
- Door hinge template
- Door lock template
- Router or wood chisel
- Door handle
- Door hinges
Measuring the Door Frame
Since we don’t have a workshop yet and it’s raining outside, we cleared off our dining table to use as a workspace and laid out the side jambs for the door frame on the table.
To get the correct width for the door frame we measured the door itself and added a 1/4″. This allows for a bit of a gap on each side of the door.
We used that measurement to cut the header and lightly nailed the header and side jambs together. Long clamps would do the job too. We also put a piece of scrap wood across the bottom to hold it all together.
Installing Door Hinges
We measured where the hinges were on the neighboring laundry room door for our guide and made those marks on the side jamb.
We laid the door on the frame and placed in 1/8″ shims between the door and frame.
Then we penciled the hinge markings to the door so we know where to sink the hinges on the door as well.
Next we marked the center of hinges. We’re using 3-1/2″ hinges so we made a mark at 1 3/4″ in our marked hinges on both the door and jamb.
We took the door off the table and set it along the side and clamped it in place so we can carve out the recessed area for the hinges, called hinge mortises. We screwed on the hinge template and cut the hinge mortises with the included router bit and used our rotozip. As we went along we ended up changing to our router which enabled us to get a smoother area carved out. You could also use a wood chisel. The point is to cut out a shallow, flat area for the hinge.
We did this for all 3 hinges on the door and screwed the hinges on.
We made the 3 hinge mortises on the door jamb as well and connected the door hinges to the door jamb and screwed together.
How to Install an Interior Door
To hang the door, we stood the whole unit — door and frame, inside the opening and placed in shims along the top and sides to hold it all in place.
Once we got it leveled we nailed the frame in to the door opening and sawed off the shims.
How to Install Door Hardware
For the height of the handle we referenced the laundry room door again and marked the height on our pantry door. Then we put the door lock template on and used the included carbon hole saws for the door lock and door handle.
Using the plate template that was included with our hinge templates, we carved out the recessed area, screwed the plate on and placed in the door lock and handle.
The final step is installing the latch plate on the door jamb. With the door closed we used the door plate to match the placement for the latch plate and drilled the hole. Then we carved out the recessed area using the template, and screwed the latch plate on.
Now we have our door on and it looks great! We got this done in one afternoon and saved at least a couple hundred making the frame and installing it all ourselves. And since we did it ourselves we know it’s done right. We hope this diy tutorial helps you to install an interior door in your home.
