Reasons Why Your uPVC Window Won’t Close All The Way

An open window might seem like a small problem, but it can pose huge risks. From compromised security to the arrival of unwanted pests, and to potential energy losses from draughts, dealing with it as quickly as possible is vital to ensuring your home stays safe and efficient.

At Total Seal Repairs, we’re often asked why a window won’t close and how to fix this. As experts in window replacement parts and repairs, we will walk you through some of the most common reasons why your uPVC window‘s not closing and how to fix it.

Common Reasons It’s Not Closing Properly

There are several reasons that may be keeping your uPVC window from fully closing, with some easier to correct than others.

Debris

Dirt, dust, or paint can accumulate around the locking points. This can prevent the window from shutting.

Locking mechanism or handle fault

The locking mechanism or handle may be broken. This can stop the window from securely shutting.

Damaged hinges

Hinges can get rusty, bent, or worn from regular use.

Dropped window

Over time, the window might drop due to frequent usage. This can make it difficult to open and close.

Warped frame

The weather, sun, or temperature changes may cause the sash to warp. This can cause the window to be out of alignment.

How to Fix a uPVC Window

Solving a window issue usually comes down to two simple steps. First, determine why the window won’t close by carefully inspecting the frame and mechanisms. Once you’ve identified the cause of the problem, you can move on to fixing it. In this guide, we’ll show you exactly where to look and share some quick, practical solutions to help you get your window working again.

Step 1: Inspect the Window

If your window won’t close at the way, it is essential to try identifying the source of the issue.

Locking points: Look for any build up of debris that may prevent the window from closing all the way.

Locking mechanism and handle: Inspect for signs of damage or missing or loose screws. Test the handle movement for tightness and listen for unusual sounds.

Hinges: Open the window fully and look for wear, damage, or missing window parts. Test the window’s movement by closing it as much as possible. If the movement is smooth, it suggests a problem elsewhere.

Window frame: Pull the window as closed as possible. If there are any visible gaps of light above or below the window frame, it may indicate the window has dropped or warped.

Step 2: Resolve the Issue

Once you have a clearer grasp of what the problem is, try the following methods to get your window closed.

Debris: Remove and clean any debris from the area with a cloth.

Locking mechanism or handle fault: Tighten any loose screws with a screwdriver or replace rusty or missing screws as needed. If the lock feels stiff, it may need lubrication. In this case, spray a light lubricant that won’t clog up the mechanism. In some cases, the handle may be worn. While a new handle can be difficult to fit, replacement is sometimes necessary.

Damaged hinges: Tighten loose or misaligned screws and lubricate rusty hinges. Severely damaged or missing hinges will need to be replaced. As uPVC has a range of window types, adjust the alignment with a screwdriver or Allen key depending on type.

Dropped window: Lift the window sash and tighten the screws. Be cautious with heavy windows, and make sure to ask for help or call in a professional if necessary.

Warped frame: Minor warping can sometimes be corrected by readjusting the hinges or through seal replacement. However, depending on the severity of the warping, severe warping may require a new window installation.
