How to put up window shutters: a simple DIY project

Learning how to put up window shutters is one of those weekend projects that looks a lot harder than it actually is. You see them on almost every house in the neighborhood, and they do a ton of heavy lifting when it comes to curb appeal. A plain, boxy house can suddenly look like a charming cottage just by adding a bit of color and texture around the glass. If you've been staring at your bare exterior walls and thinking they need a little something extra, you're in the right place. You don't need a professional contractor or a massive toolbox to get this done; you just need a bit of patience and a Saturday afternoon.

Before we dive into the nuts and bolts, let's talk about why you're doing this. Sure, shutters look great, but they also protect your window frames and can even help a bit with insulation if you're using functional ones. Most modern DIYers, though, are looking at decorative shutters—the kind that stay fixed to the wall and just look pretty. Whether you've picked out vinyl, wood, or a composite material, the process is fairly similar.

Getting your gear together

You can't really start a project without making sure you aren't going to be running back and forth to the hardware store every twenty minutes. For most shutter installations, you're going to need a good power drill, a level (this is non-negotiable), a pencil, and a sturdy ladder. If you're mounting your shutters onto brick or stone, you'll also need a masonry bit and some wall anchors.

Most shutter kits come with their own fasteners. If you bought vinyl shutters, you'll likely find these long, plastic "shutter loks" in the box. They look like big ribbed nails. If you're going with wood, you'll probably be using stainless steel screws that match the color of your shutters. It's a good idea to double-check the package before you get started because there's nothing worse than being halfway up a ladder and realizing you're missing a screw.

The art of measuring (twice)

I know everyone says "measure twice, cut once," but when it comes to how to put up window shutters, it's more about "measure twice, drill once." You want the shutters to look like they could actually close over the window, even if they're just for show. This means they should be the same height as the window trim itself.

Grab your tape measure and check the height of the window casing from top to bottom. Don't just assume all your windows are the same size. Older houses, especially, love to have slightly different dimensions for every single opening. Once you have your measurements, hold the shutter up to the window just to "dry fit" it. It's much easier to see if something looks "off" now than after you've bored a hole into your siding.

Prepping the shutters

If you're working with vinyl, you'll notice they usually don't come with holes pre-drilled. That's because every house is different. You'll want to lay your shutter flat on a couple of sawhorses or even just on the grass. Most manufacturers suggest drilling holes about two inches from the top and bottom and one in the middle on each side.

Use a drill bit that's just a tiny bit larger than the fastener you're using. This gives the shutter a little room to expand and contract as the temperature changes. If you pin it too tightly to the wall with a tiny hole, the vinyl might warp when the sun hits it in the heat of July. Nobody wants wavy shutters.

Climbing the ladder and marking the spot

This is where having a buddy helps. One person holds the shutter in place against the window, while the other steps back to make sure it looks centered and level. Use your level to be absolutely sure. Once it's perfectly straight, take your pencil or a small drill bit and mark the locations of the holes onto your house's exterior.

If you're working alone, you can sometimes use a bit of heavy-duty double-sided tape just to hold the shutter in place for a second while you mark your spots, but honestly, it's a lot safer and faster to just ask a neighbor or a family member to hold it for two minutes.

Drilling into the siding or brick

Now for the part that makes people nervous: drilling into the house. If you have vinyl or wood siding, this is a breeze. Just drill straight through your marks. However, if you're dealing with brick, you need to be a bit more careful. Try to drill into the mortar (the gray stuff between the bricks) if possible, as it's much easier to repair later if you ever decide to take the shutters down.

If you have to drill into the brick itself, take it slow. Don't use the hammer setting on your drill if you can avoid it, as it can sometimes crack the brick face. Once your holes are drilled, tap your plastic anchors into the holes until they're flush with the wall.

The final installation

Now comes the satisfying part. Line up your shutter with the holes you just made. If you're using those plastic shutter loks, you just push them through the shutter and into the wall. Give them a gentle tap with a hammer to seat them. You don't need to go crazy—just enough so the shutter is snug against the house.

If you're using screws, drive them in until they're tight, but again, don't over-tighten. You want the shutter to be secure, but you don't want to crush the material or strip the hole. If your kit came with little color-matched caps for the screws, pop those on now. It makes the whole thing look much more professional.

Dealing with uneven surfaces

Not every wall is perfectly flat. If you're putting shutters up on lap siding (the kind that overlaps), you might notice a gap behind the shutter. Most of the time, this isn't a big deal and you won't even see it from the street. But if it bothers you, or if the shutter feels a bit wobbly, you can buy "shutter shims" or spacers. These little bits of plastic sit behind the shutter to level it out against the angled siding.

A quick note on maintenance

Once you've figured out how to put up window shutters and finished the job, you're mostly done for a long time. Vinyl shutters are basically "set it and forget it." A quick spray with the garden hose once a year is usually enough to keep them looking new.

Wood shutters, on the other hand, are a bit more high-maintenance. They're gorgeous, but they'll need a fresh coat of paint or sealer every few years to keep the rot away. If you notice any peeling or cracking, jump on it early. It's way easier to touch up a small spot than it is to sand down and repaint a dozen shutters because they've started to flake.

Why it's worth the effort

It's amazing how much of a difference this makes. You'll find yourself pulling into your driveway and doing a double-take at your own house. It feels finished. It feels "designed." And the best part is knowing you did it yourself.

Whether you went with classic black louvers, deep forest green board-and-batten, or something bright and bold, you've just added serious value to your home. So, put the ladder away, grab a cold drink, and admire the view. You've officially mastered the art of putting up shutters. Now, what's the next project? Maybe it's time to look at that front door color
