Common Window Faults & How To Fix Them: A Comprehensive Guide

Having trouble with your home’s windows?

At Plan-it Windows, we know that even the most durable windows can experience issues from time to time. Fortunately, many of these issues can be resolved without the need for a service engineer or specialist tools.

Whether your windows are sticking, draughty, or suffering from condensation, by following our concise and informative tips, you can probably fix the majority of these issues yourself.

However, if you’re unsure or if the problem is more complex, the team at Plan-it Windows is always ready to assist with installing replacement windows.

What is the average life of uPVC windows?

If your uPVC windows were installed around 1999, it’s possible that they may need some attention by now. While these windows typically last for around 20 years, this lifespan can vary depending on factors like quality and maintenance. Plan-it Windows offer a 10-year guarantee with all new windows that we install, so you’ll have peace of mind for at least a decade with our windows.

Is it worth repairing uPVC windows?

When it comes to fixing issues with your windows, it’s important to consider whether a repair or replacement is the best option. The decision ultimately depends on the specific issue you’re experiencing.

If your window is sticking or not closing properly, a simple adjustment may be all that’s needed to get it working again. However, if your windows are in poor condition, or if they’ve been repaired multiple times, upgrading to new windows may be the most practical and cost-effective option. If cost is a concern then Plan-it have competitive finance deals available – just speak to the team for more information on this.

What are the most common problems with UPVC windows?

Let’s take a look at the 10 most common issues with uPVC windows as they age.

1. Window Won’t Open

This can be caused by a buildup of dirt and dust, which creates friction when you try to slide the window open. It’s also possible that the window was painted shut or that the springs and sash are damaged.

How to fix:

Start by cleaning your windows and using a lubricant spray. This may be all you need to do to make the window slide smoothly again.
If there’s paint in the crevices where the sash should open, use a putty knife to break the seal.
If the window still won’t slide, it’s possible that there’s an issue with the springs or sash. In this case, it’s best to call in our professionals to handle the problem.

2. Window Won’t Stay Up

The main reason for this happening is because the pivot bar that connects the window and the sash can get bent, snapped or warped.

How to fix:

The simplest way to fix this issue is replacing the pivot bar. This is an inexpensive part to replace and very easy to fit yourself.

3. Window Drafts

Drafty windows can make your home uncomfortable and increase your energy bills. The main reasons for drafts are poor window installation, cracks, old windows, or non-energy efficient windows.

How to fix:

If you notice drafts coming in around your window frame, re-caulking (resealing) the window or installing new weatherstripping can provide a solution. Weatherstripping creates a tight seal, while caulking seals any cracks to fix drafty windows.

4. Warping

If you have wooden windows, you might notice them warping due to moisture. This can cause bending and make it difficult to open and close the windows.

How to fix:

For minor warping, you can use filler to cover any cracks and apply a protective stain or paint to prevent further damage. If the warping is severe and affecting the functionality of your windows, it might be time for a replacement.

5. Leaking

Leaky windows are a serious problem that can lead to mould growth and rotting. Additionally, water spots on the glass can leave unsightly marks.

How to fix:

To fix a leaky window, start by cleaning and re-caulking the window frame. If this doesn’t work, it’s important to take prompt action to get a replacement – speak to our team for an incredibly competitive FREE quote.

6. Rotting and Cracking

If your wood windows start to rot, it’s important to fix them as soon as possible to prevent further damage. But before you consider replacing them entirely, there may be some simple home remedies you can try.

How to fix:

To fix the rot yourself, remove the rotted parts of the window and clean out the gap. Use wood filler to replace the damaged wood, and once it’s dried, sand and paint the wood. Finally, re-caulk the window to ensure a good seal. With a little effort, you can have your windows looking great again.

7. Fog / Condensation

Foggy windows are another sign that something with your window isn’t working as it should. With fog, the problem usually lies in the seal of the window. Heavy rainstorms, heat, and age are all factors that contribute to broken seals. Moisture leaks through the broken seals, and as cold air from outside mixes with the warm air inside your home, fog forms on the glass.

How to fix:

A defogging spray can eliminate the problem in the short term, or you could even use shaving cream. To prevent fogging, make sure you’re inspecting your windows often, ventilating your home, and use a dehumidifier to remove any excess moisture.

8. Broken Locks And Latches

As your windows age, you might experience a broken lock or latch when attempting to lock your window. Luckily, this is a minor issue that can be easily and cheaply resolved.

How to fix:

To fix the problem, look for a replacement part for your window and use a screwdriver to remove the broken lock or latch. Once removed, replace it with the new one and your window will be as good as new!

9. Scratches on the glass

If you notice scratches on your double-glazed windows, there are a few ways to address the issue.

How to fix:

You can try filling in the scratch with resin, which can be found at motor accessory or DIY stores. Alternatively, you can polish the scratch out using a lint-free cloth and a fine abrasive like cerium oxide or iron oxide. Just be sure not to use household abrasive cleaners. If the scratches are too severe, your only option may be to replace the entire sealed unit. If the damage resembles a crack rather than a scratch, then you may be soon be dealing with a smashed window. Read our in depth guide on how to deal with a broken window.
