So, your window’s a bit stiff, doesn’t close right, or maybe it’s letting in a bit more breeze than it should. It happens. A lot of people start wondering, how do you adjust a upvc window without calling in a professional? Good news — most of the time, you can fix minor issues yourself with a few simple moves and a bit of patience.
Why Windows Go Out of Line
Over time, doors and windows shift slightly. It could be the weight of the glass, repeated use, or just the frame settling into place. This is especially common with UPVC windows. They’re durable, but not immune to tiny changes that affect how they open or seal. A window that sticks, catches, or leaves a gap usually just needs a small adjustment.
And no — you don’t need to be a tradie to sort it out.
Know Where to Look
When you open your UPVC window, take a look at the hinges and handles. Most modern ones come with built-in adjustment screws. These let you move the sash (that’s the part that opens) slightly up, down, or sideways, depending on what’s out of whack. Sometimes, it’s just one screw that needs a quarter turn to make the window sit right again.
If the window doesn’t close tightly, it might be the locking point that needs a little nudge. If it drags when opening, you may need to lift the hinge side slightly. These are little tweaks, but they make a big difference.
The Right Tool Helps
A regular Allen key — the one you probably have sitting in a drawer from assembling flat-pack furniture — is usually all you need. The small adjustments you make with it can bring everything back into line. Just remember: gentle moves. You’re not forcing anything, just fine-tuning. If something feels stuck or overly tight, stop and take a second look.
It’s a lot like adjusting a door — you’re not rebuilding the frame, just helping it do what it was meant to do from the start.
When In Doubt, Ask
If you’ve gone through the motions and the window still isn’t behaving, there’s no harm in getting a second opinion. But don’t assume it’s a big job. People often ask, how do you adjust a upvc window and imagine it’s complicated. In reality, it’s usually just a matter of knowing which screw does what.
And if you've never touched it before — that’s okay. Every window has its own little quirks. Take your time, make small adjustments, and you’ll get the hang of it.
One Step Closer to a Comfy Room
At the end of the day, a well-fitted window makes your home feel better. It keeps the weather out, the warmth in, and everything just feels… right. So next time your window starts acting up, you’ll know what to check first — and you won’t be asking how do you adjust a upvc window for long.
