Choosing between Pella’s double-hung or casement Energy Star windows—anyone have thoughts?

I’ve put in a lot of both, and honestly, you’re right about the casements sealing up tighter. They press against the frame when closed, so you get less air sneaking through—especially important in drafty old ranches. But double-hungs are classic for a reason. Easier to clean, and they just look right on some houses. If you love the style, I wouldn’t write them off. Maybe prioritize casements where wind hits hardest? That’s worked for a few clients of mine.

I’ve noticed the same thing with casements—they really do clamp down and keep out drafts, especially on those north-facing walls where the wind just never lets up. One thing I’d add: if you’re planning to put screens on, casements have them inside, which can get dusty. Double-hungs have exterior screens but those can get beat up by weather. I swapped a few windows last spring and honestly, cleaning double-hungs is way simpler, especially on the second floor. But yeah, for the worst drafts, casements are hard to beat. Sometimes I mix both in the same house and it works out fine.

Mixing window types has worked for me too, especially in an older house where nothing’s ever square. I do agree with you on the cleaning point—double-hungs are much easier for upper levels. Those tilt-in sashes are a lifesaver when you’re trying not to drag out a ladder every spring. But, I’ve found the casement screens being inside actually means they last longer (no hail dents or sun warping), even if they collect more dust.

“casements have them inside, which can get dusty. Double-hungs have exterior screens but those can get beat up by weather.”

One thing I ran into: the crank mechanisms on my casements needed a bit of maintenance after a few years. Not a huge deal, but definitely more moving parts compared to the classic sash system. Also, in really humid weather, sometimes the casement seals stick a little, which can be annoying. Still, for wind and drafts, nothing beats a casement.

Honestly, I just went with what made sense for each room. Bedrooms got double-hungs for egress and easy cleaning, living room and kitchen got casements for the tight seal. It’s not a perfect science, but it works.

Mixing window styles is honestly the way to go, especially in those quirky old houses where nothing lines up quite right. I’ve done a bunch of jobs where we had to get creative because you just can’t force a modern window into a 1920s frame and expect it to behave. Double-hungs upstairs are a no-brainer for cleaning—those tilt-in sashes are one of those little things that save your back (and nerves) every spring when the pollen hits. Dragging out the ladder gets old fast.

You’re spot on about casement screens lasting longer since they’re inside. I’ve seen plenty of exterior screens on double-hungs get mangled after just a couple hailstorms or even from sun exposure over time. That being said, dust does pile up on those interior screens if you don’t give them a wipe now and then... but at least you’re not replacing them every few years.

The crank hardware on casements can be a mixed bag. I’ve had customers call me back after four or five years because the gears start sticking or the handle feels loose. Usually it’s just a matter of cleaning out some gunk and hitting it with silicone spray, but it’s still more maintenance than the old-school sash cords. Humidity definitely makes those seals sticky sometimes—especially if the windows don’t get opened much.

One thing I’ve noticed: casements seal tighter against wind, which is great in drafty spots—like living rooms that face north or kitchens by an alley. But if you’re in an area with high humidity or lots of bugs, make sure you keep up with that hardware and check for any swelling around the frame.

Honestly, there isn’t really a “one-size-fits-all” answer. Bedrooms need egress and easy cleaning, so double-hung makes sense there. Living areas where you want less draft? Casement’s hard to beat for comfort. Sometimes folks worry about mixing styles looking odd, but with matching trim and paint, most people never notice unless they’re really looking.

Funny enough, I once did a job where every single window was different—the house looked like someone played Tetris with windows from five decades. Still worked out fine after we painted everything to match... Just goes to show, function first, looks second (but not last).

That’s a good point about the casement hardware. I had a crank seize up on me during a humid stretch last summer—ended up taking it apart and finding a spider nest in the mechanism, which was a first. Still, the tighter seal is noticeable compared to my old double-hungs, especially on windy days. I do miss being able to just pop both sashes open for a breeze, though. For what it’s worth, I mixed styles in my place (double-hung for bedrooms, casement in the kitchen) and honestly, after a coat of paint, nobody’s commented or even noticed the difference.

Funny you mention the mixed styles—I've got the same setup here. Casements in the kitchen and living room, double-hungs everywhere else. Honestly, I was a little worried it’d look weird, but after everything got painted, nobody’s ever noticed or cared. I think we stress about that stuff way more than visitors do.

On the casement vs. double-hung debate: I’m firmly in the casement camp for anywhere that gets a lot of wind or needs to stay tight in winter. They really do seal up better—my old double-hungs used to rattle like crazy on stormy nights. But, yeah, nothing beats being able to crack both sashes for a cross-breeze in the bedrooms.

I did have one casement crank freeze up on me last fall. Turned out it was just gunked up with dirt and needed a little WD-40 and a wipe down. Not as dramatic as finding a spider nest, but still annoying.

If I had to do it again, I’d probably stick with the mix. Each has its perks, and honestly, nobody’s walking around checking your window styles unless you point it out.

That’s honestly so true. I obsessed over matching every window at first, but once the trim went up, nobody noticed. Curious if anyone’s had issues with condensation on their casements? My double-hungs seem to handle it better in the winter, but maybe that’s just my old house being weird.

That’s interesting—my experience has actually been the opposite. The casements in our 1910 place seem to get less frost than the old double-hungs did, especially when the humidifier’s running. I’ve always wondered if it’s down to the tighter seal on casements, or if maybe it’s just air flow patterns in different rooms. Has anyone tried using storm windows with newer casements, or is that just overkill?

Interesting seeing both sides here. I’ll just add—condensation comes up a lot with clients debating double-hung versus casement, and honestly, it’s rarely just the window type. You’re right that casements tend to have a tighter seal, especially newer models. That tighter seal can actually help reduce drafts and cold spots, which means the interior glass surface stays a bit warmer, making condensation less likely in most cases.

But it’s not always cut and dry. In older homes, you get all sorts of weird airflow quirks—sometimes the placement of radiators or vents has more impact than the window itself. I’ve seen double-hungs in an old Victorian that never sweat, while the casements in a new addition fogged up every morning... turned out the humidifier was cranked way too high in that room.

About storm windows on new casements: it’s pretty rare these days. Most modern casements (like Pella’s Energy Star line) are already double- or triple-glazed with low-E coatings, so adding storms is kind of redundant unless you’ve got some extreme weather or really want to cut down outside noise. I did see one client add storms for an extra layer during a brutal Minnesota winter, but for most people, it’s overkill—and honestly, a pain to install and operate with crank-out windows.

If you’re worried about condensation, I’d look at humidity control first. Sometimes it’s as simple as running exhaust fans longer or moving furniture away from registers. And if you’re comparing new double-hungs vs. casements from Pella specifically, both are pretty solid on energy ratings these days—the bigger difference is usually how they fit your house’s style and how much maintenance you want to deal with down the road.

Kind of funny how every house seems to have its own “personality” when it comes to this stuff…
