Easy DIY Doorway Casings

Hi Guys!  I hope you had a great week and a fabulous Mother’s Day for the all Moms out there!!  Today I want to share a simple tutorial for installing DIY doorway casings.  This is a very easy DIY that goes a long way to increasing a home’s architectural beauty! Below is a photo of our entryway before we bought our home.  There is a doorway opening into the living room on one side of the entry and a doorway opening to the dining room on the other side. Easy Doorway Casings As you can see in the photo above the doorway openings were not cased with wood trim.  Now they are!!

Before I trimmed the opening on the inside of the dining room:

Makes a big difference, doesn’t it??  Let me walk you through how very easy it is to do.

The first step may be the most “intimidating” part and yet you can see in this 1 minute video how simple and not scary it is.  The first step is to remove about 4 inches of the existing baseboard on each side of your door opening.

See how I had to cut the baseboard in order to install the bottom piece?  Check out the quick video it will take care of any questions of concerns you may have about cutting the baseboard.

The next 3 steps are as easy as 1, 2, 3.

Easy DIY Doorway Casings Tutorial

You can buy pre-cut door casing bases for about $5 a piece at Home Depot or Lowes OR you can buy an 8ft. 1×4 for about the same price and cut them to your desired lengths.  I did the latter option and cut the 1×4 into 9.75 inch lengths.  This way I got all of the bases for around $5 instead of the pre-cut option which would have been over $20.

Baseboard Casing

After nailing the bases to the wall, prop the vertical casings on top of the bases.  I chose fluted styled molding that I got at Menards at a good deal (7ft. for $5.50).

Nail them to the wall making sure to leave a 1/4 inch gap from the edge of the opening as seen below.

This is how the professionals do it!  Later you will caulk and paint it so that it  looks like it is all one piece. Next you will make the top piece of the casing which is also very simple. The top piece is made from a 1×4 and a piece of quarter round moulding.

Building Door Casings2

Add a line of Liquid Nails across the entire 1×4.

Then I placed the piece of quarter round onto the 1×4 and secured it with painter’s tape until it dried.

When the top piece is dry you can place it on top of the vertical casings making sure again to leave a 1/4 gap from the edge of the opening.

At the bottom between where the two bases are you can add a piece of wood to connect the two bases as seen below.

How to install Trim around a Doorway Opening

To do this I just measured the width between the two bases and cut a sheet of 1/2inch mdf to that width and the length to the same as the bases.

I use to wonder how everyone always got their nails all the way in without damaging the wood with a hammer.  No one ever mentions the step of using a nail setter in their tutorials so I didn’t know!:-)

Easy Door Casings

So in case you are in the DIY dark like I was you can purchase an inexpensive (maybe $4) tool to get those pesky nails all the way in, called a nail setter.:-)

The last step is to caulk the edges of the casings and paint all the molding and the top and side ends of the opening all the same color!

It will look amazing! If you have some uncased doorway openings in your home I can’t wait for you to try this!  You won’t be sorry you did!  DIY doorway casings will take your home from builder basic to beautiful!

I’m here if you have any question just leave them in the comment section!  I hope you have a great week!

    This project turned out really lovely and makes for so much more personality in your home! I enjoy your site & appreciate that you share all the littlest details (but so important, like the nail setter) in your tutorials. 🙂

    These are great! We recently finished our basement and I was hoping to remove two doors and add casings. I think this would work if I tore off the molding, right? Also, we have baseboard heat – do you think I could just trim it out around the baseboard? The baseboard backs up to the molding so I couldn’t take off 4″ on one side… 🙂

      I just did a little Google search for molding archways. It appears molding is more flexible if it is skinnier so one option is to run a piece of molding through a table saw to break it into 3 pieces and then install them back together like this video explains, http://wishihadthat.com/arch-molding.aspx. Another option is to buy a 4 x 8ft. Sheet of mdf ($25). Trace the curved part of your archway on large paper and then draw it onto your mdf sheet, measure out the width you want the molding and draw a line at that point parallel to the original curved line. Then with a jig saw ($40) cut out the arch drawing you made on your mdf sheet. Voila you have a custom molding for the top of your archway! Hope this helped! You can try googling for perhaps more ideas.:-)

    We could sure use some nice door way mouldings in our single wide, typical plastic junk around door ways and windows. When we bought this place in 2006 hubs was working for contractor and guys that did building and finish work gave him all kinds of “scraps” which he used around most of our windows, what a difference it made. Also used much of it for base board, there were none.
    Not our dream house but when we moved here from KY, found out how expensive to buy property compared to KY so we bought what we could afford. Plus wanted to be out of city so more expensive out here, but so much quieter and private. We have 16×80 single wide mfg. home on 1/2 acre.
    We’ve done what we can to fix up when we can afford to on our SS. Hubs was out of commission for while after he had stroke (2010) and recently knee replacement. Also put us in hole for long time after hubs stroke as no more extra money and recession on top of it.
    We had to have new roof on this Spring so oldest son came up from San Diego to put metal roof on for us just before hubs surgery at end of April. Youngest son, (lives in Grand Junction) came out to help, they got it done in two days. Won’t have to worry about roof for rest of our lives, boy is that a relief.
    You were so smart buying length of lumber instead of paying for ready made. If people want to and put their heads on it can save with alternate, always good to think on it before rushing out to buy ready made. It looks fantastic, good for you gal.
    Your home is so nice, love it. Would love to have regular house but at our age (middle 70’s) we’ll be fine in our mfg. home. From looks of your home you are good housekeeper and keep things really nice. All experience you get fixing home up will stand you in good stead for rest of your life. Enjoy your lovely home. Great tutorial.

    I love this tutorial, it is exactly what I was looking for. I’m not the most handy person but I think I can do this! I was wondering what you did with the inside of the frame? Also, we have base board down already, can I put the base of the casing on top of that? Idk if these are stupid questions or if they will make sense to you. Haha

    Thanks!

      Hi, Amy, you can totally do this!! Yes, if you already have a baseboard that is thicker or the same size as the casing then you can go ahead and put the casing on top of it. I’m not exactly sure what you mean by “inside the frame”. Do you mean the space inside the doorway opening? If so, I painted all white with the same white paint I used for the casings. Let me know if this isn’t what you were asking!:-)

I Love Hearing from You!
