Double Glazing Wirral - Frequently Asked Questions
How much does it cost to replace double glazed windows?
Double glazing windows don’t have a set price. Factors such as type, number of windows, difficulty of installation, and size of installation team required all affect the final cost. With extra options including triple glazing, which you might opt for if you are keen to further reduce noise, your costs will be worked out accordingly. Contact us for a no-obligation double glazing quote.
Take a look below to see what we mean:
- Windows and Doors – Doors and windows make up some of the areas of your home that lose heat the most. Up to 25-30% of energy is lost through these areas. Our windows are double-glazed and our doors built with insulating material, meaning they stop nearly 100% of heat from leaving through these spaces.
- Roof – Your roof is also responsible for allowing heat to escape. Heat rises, and as such, you need insulation in your roof space to stop any energy from being wasted. It’s said that up to 25% of heat can be lost through these spaces without insulation.
- Solar Panels – Solar Panels can generate energy on their own from the sun, meaning they convert the daylight from the sun into usable energy for your home. This works even in the cloudy climate of Scotland, as Solar Panels have evolved in efficiency rapidly since their inception. This energy can be used, and even stored in batteries for later. It costs nothing to use, essentially rendering your electricity bill zero.
Is it possible to repair double glazed windows?
Absolutely! Not all windows need replacing, some can be repaired. We offer a window repair service, so if you feel like a repair is better suited to you than a replacement, contact us today and we’ll provide you with a free quote for the work when we know more about the project.
How long will replacing double glazing take?
That depends on the number of windows you need replacing. As a rule, a standard window will take just 1-2 hours to replace. If you’re replacing every window in your Wirral property, then it may take us a few days to complete the job.
