Casement vs Double Hung Windows Cost: What You Need to Know Before You Buy

Don't get me started on people picking windows just because they look good on a showroom floor or some trendy Pinterest board. I’ve spent 25 years in the trenches installing windows from Andersen, Pella, Marvin, Jeld-Wen—you name it—and trust me, there’s more to choosing the right window than just the sticker price or the latest marketing pitch. If you’re stuck between casement and double hung windows (actually, we'll also touch a bit on awning style since it's close kin to casements), and you want to know what kind of hit your wallet will take and what makes sense for your home’s ventilation and maintenance, you’re in the right spot.

Window Price Comparison: Casement vs Double Hung

First thing’s first: the cost. Everyone wants to know, “What’s the bottom line?” so let's start there with some realistic numbers based on what I’ve seen installed over the years.

Window Type Material & Brand Average Price Per Window (Including Installation) Notes Vinyl Casement Jeld-Wen or similar $450 Standard size, basic vinyl, with professional install Vinyl Double Hung Jeld-Wen or similar $400 Standard sizes, basic vinyl with professional install Wood-Clad Casement Marvin, Andersen $800 - $1,000 Higher-end brands, better materials Wood-Clad Double Hung Marvin, Andersen $750 - $950 Similar to above, a touch cheaper than casements Awning Window Pella, Marvin $600 Vinyl and wood-clad versions

As you can see, casements generally cost more, especially in wood-clad versions. Vinyl double hung windows tend to be the budget window replacement go-to because they’re cheaper and easier to manufacture. The difference isn’t massive on a per-window basis, but if you’re outfitting a whole house, it adds up.

Ventilation Differences and Airflow

Ever wonder why certain rooms feel stuffy even with windows open? That’s where the type of window and how it opens really matters.

Casement Windows: These are hinged on the side and crank open outward. When open, they catch the breeze like a little sail, funneling air right inside. Great for maximizing airflow, especially on breezy days. Makes sense, right? You get better ventilation because the sash literally pushes the window out into the wind. Double Hung Windows: These slide up and down with two sashes. They’re easier to operate and traditional in style. The drawback? When you open only the bottom sash, you get some airflow. If you open both top and bottom sashes, warm air escapes the top while cool air enters the bottom, which is smart. Still, the airflow isn’t as pronounced as with casements. Awning Windows: Hinged at the top and open outward, awnings are similar to casements but usually smaller. They let in good airflow without allowing rain in if the window's open during light showers.

If fresh air is your priority, casement windows outperform double hung. But keep in mind, they swing out, so you’ve gotta be mindful where you install them.

Common Installation Mistake: Blocking Walkways With Casements

Speaking of that swing, I can’t stress enough the number of times I’ve seen guys (or homeowners DIYing and winging it) install casement windows where opening them blocks a patio, a narrow walkway, or worse, a fire exit route. Don’t do that. It’s not just annoying—it’s a safety hazard. If your casement window pushes out into a busy walkway, every open window becomes a trip hazard or something that can get bashed or broken off. So always measure your clearance three times, and think about traffic paths around your house before you pick casements.

Security and Locking Mechanisms

Not all windows are created equal when it comes to locking up your house tight.

Casement Windows: Usually have multi-point locking hardware along the sash that pulls the window tight into the frame—great for security and keeping drafts out. Because the window closes sash against frame, it makes breaking in a bit tougher. Plus, since the hinges are on the outside but concealed, prying them open is tricky for thieves. Double Hung Windows: Often have simpler locks that latch the two sashes together, or lock into the window frame. Secure? Yes, but generally not as tight or secure as casements with their multi-point locks. Awning Windows: Like casements, awnings also feature multi-point locks and tight seals, making them a solid security option.

If security is a high priority—say you live on a street with heavy foot traffic or had a break-in in the neighborhood—I recommend casements or awnings over double hungs.

Ease of Cleaning and Maintenance

Here’s where double hung windows shine in some folks’ minds. They’re easier to clean from inside the house because the sashes slide down, and many models tilt in for cleaning. No ladders needed if you have upstairs windows.

Casements can be a pain in this department. You usually have to open them all the way, and for upper floors, you might need a ladder or a good stretch arm. Awning windows, being smaller, aren't too terrible to deal with but still not as convenient as double hung tilt-in sashes.

Maintenance-wise, both styles require regular checking of the seals and caulking around the frame to keep water out. I can’t tell you how many leaks and drafts I've seen caused by sloppy caulking or old, cracked seals. Having a level, a caulk gun, and shims handy during installation is crucial for a tight fit—if the window isn’t square, it won't seal right, no matter how new the glass is.

So, What’s the Bottom Line?

Here’s the no-nonsense rundown:

If budget is tight: Vinyl double hung windows typically cost less and offer decent ventilation and reasonable maintenance. If you want maximum ventilation and security: Casement or awning windows are your best bet, but be mindful of where they open to avoid blocking walkways. If ease of cleaning is a priority for upstairs windows: Double hung with tilt-in sashes are king. If longevity and aesthetics matter: Wood or wood-clad windows from Andersen, Marvin, or Pella are more costly but hold up over the long haul and offer more elegant options.

Beware the “most expensive window type” marketing hype. Casements aren’t always the priciest, but high-end wood double hung windows from brands like Marvin and Andersen can rival or exceed casement prices. You’re paying more for materials, craftsmanship, and style, not just for the window type.

Remember, proper installation with the right tools—a level, shims for squaring, and a caulk gun to seal the frame—is half the battle. No fancy technical wizardry can fix a crooked window or shoddy framing.

Final Tip Before You Buy

Matching window type to your climate and lifestyle is key. Don’t just copy your neighbor or pick the priciest model thinking it’s the best windows for basement best. Consider how much you open your windows daily, if you have kids or pets who might jam or break crank handles, and what kind of airflow you want in which rooms.

And if you’re unsure, get a pro to measure and recommend what works best. I always measure three times—never twice—and check the environment before I install. Those extra few minutes save headaches and money down the line.

So next time you're staring at a “window price comparison” chart or a sales brochure boasting “lifetime warranties,” remember: real-world performance beats flashy promises every time.
