How often should you replace your windows?

Most window experts would agree that quality windows last for around 20 years. After that, you can start thinking about replacing them.

However, it is very common for people to be unsure about whether it would be worth it for them. Here are some considerations that should help you to decide if it’s time to replace or not:

  • Are they broken (warped or damaged)?

Is the frame broken anywhere? Does your glass fog up? Are the frames rotted (soft to the touch)? Do they stick when you try to open them? In these cases, you would benefit from replacing your windows.

  • Do you want to reduce your energy bill?

Older windows are not as effective as keeping the cold out in winter, and heat out in summer. If your windows are not efficient, you could save a lot of money in energy bills by having them replaced. Talk to a window expert to see if that is the case for you.

  • Are you selling your home?

Worn out or old windows can be a real eyesore for new buyers – they will notice the small details that you have gotten used to over time. This is why it can be very beneficial for you to replace your windows in anticipation of a sale. You might get a better price and sell faster!

  • Are you looking for a style update?

Period homes sometimes have beautiful timber sash windows replaced with uPVC casement windows to save on costs, but these can end up looking unsightly and standing out for all the wrong reasons. Perhaps you want a sleek modern look with aluminium frames, or want to fit in more with your conservation area. New windows might be just the ticket.

The benefits of replacing windows and doors

How beneficial would it actually be for you to replace your windows and doors? Hard to say. Here are some considerations for you to think about:

  • Increase the value of your home

Depending on how worn out and damaged your windows are, you could significantly increase the value of your home. This is even more applicable when you put in french windows, a shiny new front door or a bay window. These also add curb appeal that could speed up the sale process if you decide to move.

  • Save money

Again, this is not true for everyone, but if your windows are over 20 years old, are damaged, warped or single glazed, you will undoubtedly benefit from installing new ones. You will save on energy expenditures in the long run, and new windows have a long lifespan when they are installed in the correct way.

  • Stop condensation

Do your double glazed windows fog up, or allow moisture to condense on them in the morning? This probably means that the seal is broken, and your double glazing is essentially useless. You can simply repair this damage, or perhaps replace the whole sash which is cheaper than replacing the whole window! Talk to a window provider for more information.

  • Reduce noise

If you suffer from noise pollution in your area, which keeps your family up at night and encroaches on your life, you will greatly benefit from getting some windows. This will improve your peace of mind and your health (noise pollution sometimes has noxious effects).
