How to Build Interior Window Shutters.

If you’re here, you’re interested in interior window shutters.  I don’t blame you one bit. They look good in traditional,  contemporary or heritage homes and best of all you can custom build interior wood shutters yourself. No, really you can.  I did.  Here’s how.

White shaker style DIY interior shutters in heritage home.

My neighbours have interior shutters in their historical home and I’ve always loved them.  So I stole the idea.

Some of my best ideas are stolen. The same goes for my jewellery.  Don’t worry about stealing ideas, everyone does it.  The one thing you should pay attention to is making the idea work for you and your circumstances.  Adapt it, change it and make it your own.

I get SO many emails about the plans and measurements of DIY Restoration Hardware sectional and my chicken coop. But I built both of these things to specifically work in my space. You do you!

For the shutters I  wasn’t worried so much about light control, this house is dark on the sunniest days, but if you need something to totally block out light, nothing is going to do it as well as solid wood. Suck on that black out curtains.

I knew my neighbours’ interior shutters wouldn’t work for me because I didn’t have space on either side of my windows for opening them up.  They have 2 shutters on each window that open up just like cupboard doors, laying flat on the walls on either side of the window.  That wasn’t an option for me because I have too much stuff on either side of my windows to swing open a 15″ shutter on either side of them. There would be nowhere for the shutters to go.


How do interior shutters work?

Like a regular, old shutter.  They’re mounted on hinges to your interior window frame. They swing open and closed just like a cupboard door or shutter.

If the shutters are painted the same colour as your walls they disappear both when they’re open or closed.

More so than any other window treatment, inside shutters will give you complete privacy when they’re closed and also keep the heat of the day out which means a cooler house in the summer.


After a good 2 years of thinking about them on and off I configured a way I could make wood shutters work in my house. 

These are classic interior shutters like you’d find in an old English home, they are not plantation shutters.


Hinged Interior Shutters

MATERIALS

1/4″ birch plywood sheets (good on both sides)

1/4″ flat, square edged trim (poplar)

Non Mortise Lid Hinges and screws

1″ narrow hinges and screws (4- 6 hinges total per window)

Wood glue

Tape Measure

Clamps

Iron on Edge Banding

File

Sandpaper/Palm Sander

Drill and bits

Mitre Saw

 

INSTRUCTIONS

1. Measure the width and height of the interior of your window.  Plan to make each of your shutters 1/8″ smaller than the opening.

TIP – Take the window measurements from a few different places.  If they’re different it means your windows aren’t square.  If that’s the case, use the smallest of your measurements.

I bought 5′ x 5′ birch plywood sheets and had the widths of my shutters cut at the lumberyard.  They can do a MUCH more accurate job on their table saw with these long panels of wood than I can when cutting them lengthwise.  I just gave them the measurements of all my shutter widths and had them cut my plywood panels into strips.  Once I got them home I just had to worry about cutting them to the right height with my mitre saw.

(The lumberyard cut my 5′ sheets into strips that were the widths I needed for shutters, then when I got the strips home, I cut them to the right length)

2.  Once all your panels are cut to size you can cut your trim to match.  This is an easy job with a mitre saw.  The trim then gets glued into place with wood glue.

TIP – Use an old credit or gift card to spread the glue.

3.  You need to put trim on both the front and backs of the plywood so the final thickness of your edges will be 3/4″.  This is what you need for the hinges.  Plus if you only put trim on one side, the shutters would be unfinished on the other side which is more offensive than dusty rose curtains.

*** If you can’t buy trim that’s long enough for your shutters you may have to piece some together to make a long enough piece.  That’s what I did (by cutting the edges of the trim on a 45 degree angle and sliding them together).  Like this.  It’s more discreet than butting the 90 degree ends of the wood together.

4.  Clamp your trim as soon as you get it placed.

Red clamps scattered around partially made interior shutters.

TIP – Double check that your edges are still lined up after clamping. Clamps can pull the wood off kilter.

4. Once your edge trim is applied you can lay your hinges to what will be the backside (visible from the outside of your house) of your shutters.  Pre-drill your holes.

TIP – I started out using brass hinges but abandoned them because brass screws are SO soft.  Even with pre-drilling my holes I was stripping the screw heads. Use stainless or zinc hinges.

5. Screw the hinges in, making sure the wood is butted up together evenly.

TIP – Technically you could use only 2 hinges on each shutter, but the additional hinge in the middle helps keep the flimsy 1/4″ plywood from warping.

6. Even the shortest screws will come out the back of a 1/4″ piece of plywood.  File the tips that protrude through with a metal file.  It will just take a few zips with the file.

7. Because you’ve added trim on top of plywood the edges of your shutters are going to be hideous. Ugly little things.  Cover them up with iron on banding (which is made especially for this purpose).

TIP – Don’t forget to run a block of wood with a sharp edge down your edge banding after you iron it to help everything stick well.

Please notice the scar on my hand from accidentally chopping my hand instead of a piece of kindling with an axe.

TIP – You’ll still have to trim the banding. I use an X-Acto knife for this.  After trimming it, run your file down the edges to dull and flatten them even more.

 

8. Hang your shutters!

9. Check to make sure the shutters open and close smoothly.  Adjust your hinges if necessary.

10. Now you can finish your trim.  I didn’t want to be able to see the seam down the centre of these shutters so I’m covering them up with a piece of trim. It runs directly centred over the seam but is only glued on ONE shutter.  This way it covers the seam but you can still bend the hinges.    Also measure and cut your last pieces of trim for the tops and bottoms of the shutters.

11. Glue and clamp all your final trim.

12. Sand off any areas where the trim isn’t perfectly flush.  I had to do this on a couple of spots where I joined the wood.

13.  Now paint ’em.  I painted my shutters with my Wagner sprayer because you get such a smooth, fine coat of paint.

You could also use a microfibre roller for your shutters.

Just make sure to prime the shutters first, sand them after priming and then give them 2-3 coats of paint.

You’re done!  I know it seems like a lot of steps and work but it’s all fairly straight forward. Time consuming?  Yes.  Terribly complicated?  No.

 

How much do interior shutters cost?

To buy custom wood shutters for inside your home would cost thousands of dollars.

For this DIY version, each window treatment cost approximately $125.  I built 5 of them for a total of $626.   This cost includes all the plywood, trim, hinges, screws, edge banding, glue etcetera. It does not include the cost of paint. The cost will vary a bit depending on the size of your window.

QUESTIONS & ANSWERS

Do these look homemade?  Nope. At least I don’t think so, lol.

Can I have curtains too?  You don’t really need them, but sure you can have curtains too.  I’d make sure they’re very plain though with no pattern otherwise it might just look like a jumbled, busy mess.  I’m actually considering adding black velvet curtains for the winter months.

I’ve been living with these for a few  years now and they still work perfectly and I still LOVE them. They’re simple, elegant and discrete. Because of that I’ve decided I’ll eventually be doing them for the entire house.

If you’ve been trying to come up with the perfect window treatment and you’re liking this, feel free to steal the idea. I’m perfectly happy with you doing that.  And I just checked – my neighbour is too.

    Good idea but fine woodworkers would execute this far differently and ALWAYS router the edges of every board even if it’s a deck board. We love our Bosch router!

  2. m'liss says:

    They look great.
    I am trying to become more handy with no experience & few tools. You have helped a lot.
    Do you have anything on having a door or how to get a door to hang correctly?
    I live in an old house, where nothing seems to be plumb & if it is, wait a month & it’s not. I have old wooden & glass window storm doors that rarely close correctly. I know I should just replace them, but I don’t want to part with them.

  3. Cheryl says:

    Just had to let you know I purchased the Eufy on your recommendation. It works just as you described. I love it and wish I had gotten one much sooner!

  4. Caroline says:

    Hello! Great job!. What brand/type of paint did you use? I am also building some solid shutters and I’m wondering if paint choice is a consideration given these will be in the window, exposed to UV and heat. How are your painted shutters fairing?

    Thanks!

  5. Becky Justen says:

    Hello…I LOVE this idea! They look beautiful.. My husband and I are going to attempt these..I just wondering if you could give a suggestion of how to cover 3 total windows with still a shutternon either side. I want light to shine in during the day but want privacy also. I definitely don’t want curtains. Now that we’ve moved the tv, I no longer have to worry about the glare on the tv.. I also am only planning on them being 3/4 of the actual length. I tried to attach a pic but it’s not letting me. Each window is approximately 22″ wide and 61″ long with trim on all sides, the middle window included..

  6. Rick says:

    To avoid stripping brass screw heads, first install a steel screw of the same size. The steel screw will thread the hole and, unless you try to drive it all the way through the wood, allow the installation of the brass screw without undue force.

  7. Nicole S. says:

    In your tip before step 6, I think you mean “additional hinge” not shutter.

    You mention you took the shutters down to paint them. Did you also take them down to attach the final trim? I’d have thought it’d be easier to attach when the shutters weren’t swinging around on hinges?

  8. Alena says:

    My advice would be to not apply the clamps without any additional padding. If you don’t have any small pieces of plywood (for example) that you can use, fold a paper towel several times lenght~ as well as widthwise and insert these between the clamp and the shutter. The pads on the clamps are notorious was making little indentations in the wood that are hard to get rid of.

  9. Jan in Waterdown says:

    Bogs as woodworking tools? well that sure is thinking outside the box . . . err boots 😏. Well played.

  10. Catherine says:

    You mentioned in a previous post that you used “A few magnets here and there and a latch (that is actually a picture hanger)” to keep the shutters from popping open. How does this work?

  11. Trish says:

    How do they stay open? Or stay closed? Thanks

  12. Linda says:

    These look fabulous! I used to be a sewer (person who sews, not a drain) but now I prefer wood-working. So much more predictable and forgiving. I love the way you over-lapped the center piece to hide the hinge, very clever. However, I might use a ‘piano hinge’ for greater strength and stability.

    • Karen says:

      Hi Linda! I forget why I didn’t use a piano hinge, but there was a reason for it. I can’t of course think of what it was right now, lol. ~ karen!

  13. Danni McLaughlin says:

    Wow, these look fabulous and I am going to do them on a super sweet but woefully drunk-uncle’d 1928 shack we just bought at the beach. It has some of those weird long and skinny horizontal windows in the bedrooms. Gotta cover them, but they are high and curtains would look stupid and the cafe curtains on there now just block the view. This will work, provided they can make the span without sagging. Thanks Karen, you’re a star.

  14. Teresa Chandler says:

    I got distracted by the stacked planter outside your beautifully painted shed. If you didn’t make that, I’ll bet you could figure it out and show us how… hint, hint. That is a perfect Spring project and since we still have snow here and are expecting more this weekend I REALLY need something to help me believe Spring will ever come.

  15. Irena says:

    Love this idea. Question: how did you paint the shutters with the sprayer indoors? Doesn’t the spray go everywhere? Thanks.

  16. Sabina says:

    Fabulous!

  17. Arlene Topps says:

    Well done! They look great!!
    You have such pretty windows with the transom above….
    I never noticed that before!

  18. Mary W says:

    Black velvet curtains for winter – sounds as good as hot chocolate.

  19. Bill says:

    Prior to clamping, sprinkle a small amount of table salt on the wet glue to inhibit the parts from sliding

  20. Jill says:

    Would it not be easier to paint prior to hanging? Did the sprayer make a mess inside your house?

    • Karen says:

      Hi Jill. It wouldn’t be much easier to paint the wood prior to assembling them. You’d still have to touch them up because cutting the wood inevitably causes splintering. Either way it’s going to be a pain. I took the shutters down and painted them outside. :) Although technically if you tape everything off with plastic you can use this sprayer inside. ~ karen!

  21. Marna says:

    Wow, that’s awesome!

  22. ecoteri says:

    how can I do this when I have two windows side by side with a window seat? there is a 5-6 inch chunk-of-wood between the windows. the sill isn’t very deep. Sigh, I need to make honking big shutters, don’t I – ones that only open to the side? the windows are 3 feet wide (well, maybe 2′ 6″ – each) . waaaah. these are so awesome. I don’t need them, but I want them.
    Ah well, enjoyed the two posts.
    Back to avoiding cleaning chicken eggs for the farmstand. and avoiding planting potatoes because I am lazy. and figuring out how to deal with chicken fleas. er. back to my real life, after I give up pretending that I will ever build shutters for my almost 100 year old farmhouse. Perhaps I will arrange for insulation, first.

    • Linda Scott says:

      You know, I have the same problem basically. I was thinking may doing (or attempting) wooden shutters that hang Roman shade style and using a wooden cornice (hinged so it can open to receive the now thick group of shutter sections) to hide them when fully open. I don’t know; it’s just a thought. Maybe do a cardboard mock-up to size before attempting?

      • Abigail says:

        Hi Linda, did you do this? I’d like to do it too, but have 0 experience so need photos and detailed instructions. Did your work out well? Thanks. Abi

  23. Garnet says:

    Such a simple idea – no wonder I never thought of it. “Curtain” material could also be used in place of the interior plywood panel, stretched across the frame. In fact… oh so many creative applications! Thankyou for this great project.

  24. Edith says:

    Soooo much better than the mauve curtains. You did a great job, as usual!

  25. Carol says:

    They came out beautiful! Thanks for the plans! I have a couple windows I would like these on! Great job!

  26. Auntiepatch says:

    Ummmmm…….you are suppose to wear the safety goggles not eat them…….

    • Dan says:

      Was going to add this comment as well. PPE doesn’t do any good if you don’t wear it. Take it from someone who has had a doctor come at their eye with what amounts to a surgical-grade dremel tool to get the embedded stuff out.

      • Karen says:

        K. Everybody calm down. If you look at the photo you can see my hand isn’t on the handle. I’m not using the saw, I’m lining the wood up. ~ karen!

  27. Kristin says:

    Very nice and what a great idea!

  28. Isabella says:

    You’re such an accomplished, smart little perfect person. You little show off. Kudos.
