If your home is starting to feel colder, noisier, or more expensive to heat, your windows could be part of the problem. For many homeowners across Perth, new uPVC windows can give your property a fresh look while making it warmer, quieter and more energy-efficient.
If you’re considering replacing your windows, you’ll probably have one big question: how much will double glazing cost in Perth? At Cairnview Windows & Doors, we help homeowners in Perth and Perthshire replace their windows with trustworthy, expert advice.
Replacing your windows doesn’t have to be confusing. By understanding what affects the cost will help you to choose the right windows for your home and budget. In this blog, we’ll explain the factors that go into the cost of your double-glazed windows and help you make a more informed decision.
How Do I Know If My Windows Need to Be Replaced?

Before you start researching prices, you’ll need to be sure that new double-glazed windows are right for your property in Perth. Here are some signs to look out for that could indicate that it’s time for new windows:
Single glazing: If your home still has single-glazed windows, replacing them with modern double glazing can improve comfort, reduce heat loss and cost you less on those energy bills
Cracks or chips: Signs of damage like this can develop into bigger issues and may be a sign that your window might need replaced soon.
Signs of rot: Soft, squishy or blackened wood suggests that the wooden window frame is rotting.
Condensation in your window: Condensation on the inside of your window happens when moisture in the air meets a cold glass surface and it can be a sign that your windows aren’t providing sufficient insulation
Draughts coming in: Hold your hand over the window; if you can feel a cold draught, this can be another sign of poor insulation or that gaps have formed in your window.
More noise: Increased outside noise also suggests that there are gaps in your window and can make your home less peaceful.
Any of these sound like your windows? It might be time to think about getting new uPVC double-glazed windows.
Factors Affecting Cost of Double Glazing in Perth
Whether you live in Perth city centre, Scone, Bridge of Earn, Auchterarder or anywhere across Perthshire, the cost of replacing your windows will depend on the style and specification you choose.
Every home is different, so it goes without saying that there is no set cost for new windows. Across Perth and Perthshire, many houses have unique layouts and period features that can influence the overall cost. The final price will depend on several factors, including:
- Number of windows: Naturally, the more windows you need to replace, the higher the overall cost is likely to be – although buying in bulk may save you more money.
- Type of window: The style of window you choose will influence the overall cost. A simple casement window is often the most cost-effective option, while bay windows, sliding sash windows and bespoke shapes typically require more materials and installation time.
- Finish: Prices vary depending on the colour and finish such as matte or gloss finishes to choose from.
- Hardware: Different handles such as monkey bar or standard handles, can have different prices.
- Glazing: Standard double glazing will cost less than acoustic or triple glazing options.
- Size: If you have a particularly large or uniquely shaped window to fit, it may take longer and therefore cost more.

What Type of Glazing Is Best For My Home in Perth?

You might have heard of triple glazing and be wondering if it is a better option for your home. Three panes of glass can offer additional insulation, but for many homes across Perth and Perthshire, high-quality double glazing provides an excellent balance of performance and value and can be just as effective for your home.
There is also acoustic double glazing, which is a great option for those living beside a main road or requiring more sound insulation. You can read more about it in our handy blog.
