Windows are one of the most important parts of any home. They keep us warm, let in natural light, and protect us from the elements. But because they are so exposed, they can also be prone to wear and tear over time. Whether you have noticed a small scratch, a hairline crack, or foggy glass between your double glazing, it is always best to deal with these problems as soon as possible.
In this guide, we will look at three of the most common window issues: scratches, cracks, and foggy double glazing. You will learn how to identify each one, what you can do to fix it, and when it is best to call a professional like RPS Double Glazing Repairs for expert assistance.
Start by running your fingernail gently across the mark. If your nail glides over it smoothly, it is a surface scratch and can usually be treated at home. If your nail catches, the scratch is deeper and may require professional help.
Mix a small amount of baking soda with water to make a paste. Apply it to the scratched area with a soft, lint-free cloth and rub it in circular motions for a few minutes. Wipe away the paste with a clean cloth and inspect the glass. You may need to repeat this process a couple of times to see improvement.
Ordinary white toothpaste works in a similar way because it contains mild abrasives. Apply a small dab to a damp cloth, polish the scratch gently, and wipe clean. This is a quick and easy fix for faint marks.
A cracked window is a more serious issue than a scratch. Cracks not only affect how your window looks but can also compromise its strength and energy efficiency. Once a crack appears, it can spread quickly, especially in double glazed units where temperature changes cause expansion and contraction.
Stress cracks often appear without any visible impact and are usually caused by sudden temperature changes or pressure differences between the inside and outside of the window. They can start small and grow over time.
Impact cracks occur when something physically hits the glass, such as a football, stone, or garden tool. These cracks usually have a clear point of impact and radiate outward.
If the crack is small, you can use clear nail polish or epoxy resin as a temporary seal. Apply a thin layer over the crack to prevent dust and moisture from entering. This can help stop the crack from spreading until a professional repair can be arranged.
When you notice fog or condensation between the panes of your double glazing, it usually means the seal has failed. This is one of the most common window problems, and it affects both the look and performance of your windows.
Each double-glazed unit is made up of two glass panes separated by a spacer bar, often called a swiggle strip. This bar contains a drying agent and creates an airtight seal that keeps moisture out. Over time, the seal can wear down due to weather changes or simple ageing. Once it breaks, moisture seeps into the space between the panes and causes that cloudy, misted appearance.
Unfortunately, there is no reliable DIY fix for foggy or misted windows. Some online guides suggest drilling holes in the glass or using dehumidifiers to clear the moisture, but these methods rarely last. They can also cause more harm than good by damaging the glass further or letting in more air.
The best way to restore your double glazing is to replace the failed sealed unit. A professional repair company can remove the old unit, clean the frame, and install a replacement double glazed unit without having to replace the entire window. This restores visibility, improves insulation, and makes your home look newer and brighter.
While some surface issues can be handled at home, deep scratches, spreading cracks, and misted panes are best left to the professionals. Working with glass requires skill and care, and incorrect handling can be dangerous.
A specialist in uPVC window repairs can identify the root cause of the issue, fix it safely, and ensure your windows continue to perform as they should. They have the right equipment to reseal or replace glass without damaging your existing frames. Professional repairs also help you avoid recurring problems that might occur if temporary fixes are left too long.

Prevention is always better than cure. By caring for your windows properly, you can extend their lifespan and reduce the chances of needing major repairs.
Here are a few tips to help you look after your windows:
Clean regularly with care
Use a soft microfibre cloth and mild cleaning solution to avoid scratching the glass. Avoid harsh chemicals that can weaken the seals around double glazing.
Inspect your windows a few times a year
Look for early signs of condensation, cracks, or small chips. Catching these issues early can save money in the long run.
Maintain your frames
Whether your windows are wooden or uPVC, keeping the frames clean and free from dirt or mould will help prevent long-term deterioration.
Keep plants and branches trimmed
Overgrown trees or shrubs that touch your windows can cause scratches or impact damage during windy weather.
Scratches, cracks, and foggy double glazing are problems most homeowners face at some point, but they do not have to become major headaches. Light scratches can often be polished away with gentle care, small cracks can be managed temporarily until replaced, and misted panes can be fully restored by fitting replacement double glazed units.
The key is to act quickly before minor problems become costly repairs. For peace of mind, professional double glazing repairs ensure your windows remain safe, efficient, and visually appealing.
