How much can you save by replacing your double glazed windows?

If you have old single glazed windows, the benefits of replacing is definitely something worth considering. The savings will be anywhere from £150 to £135 a year, all depending on the type of double glazing you’re installing. You can even obtain window replacement grants to help improve your windows’ thermal efficiency.

The savings you get will in the long run cover the double glazing cost of the windows. Making the replacement even more beneficial for you as a homeowner.  

When replacing your double glazed window there are 2 ways to go about it: replacing the glass panel, or replacing the whole window. Replacing double glazed panel cost will often be lower than replacing the whole window. 

Replacing the glass panel is a replacement of double glazed glass only, meaning no replacement of the window frame. If you choose this option you have to be sure that your window frame is still in good condition. If not the good features of double glazing will be lost and the replacement will be useless.

You can replace every type of window with double glazed windows. The double glazing option is not only limited to windows, you can also get double glazed doors to further make your home more energy efficient.   

What does double glazed window replacement involve?

The double glazed windows replacement process varies from project to project. This is because there’s many different decisions to make when replacing windows. One of the main decisions is how many windows need to be replaced. 

Some replace one window a year, some replace the windows by sections of their house, others by storeys of their house. A window installer will usually recommend that you replace all windows that need to be replaced at the same time. Especially if you are replacing windows for the sake of higher energy efficiency. 

The whole process of double glazed windows replacement comes in 5 small steps:

  1. Finding the right installer near you: Finding the right installer is critical to know what the cost will be. It is recommended that you compare multiple quotes to find the best deal. 
  2. First home visit: After deciding on an installer, they will visit and assess the needs of the installation and the options that you have.  
  3. Reviewing formal quotes: Following the home visit you will receive the formal quotes. Now it’s time to decide which installer you would like to work with. At this point you most likely will have to put down a deposit of 10% or 20%.
  4. Confirming dates: Your installer will confirm the dates of installation and how long the process will take. It is a good idea to keep in contact with the installer in the meantime.  
  5. Make the final payment: After the work has been completed you will put in the final payment, and you can now enjoy your new double glazing windows. 

A straightforward window replacement will usually take around an hour. The precise time frame will depend on the complexity of the project and the number of windows that need to be replaced. 

For a project with more windows you can usually expect 3-4 windows to be replaced per day. If you’re replacing wooden windows that need priming and paint this process will of course be longer. 

When starting the process of replacing double glazed windows, there’s some things you as a homeowner can do to make sure that the process runs smoothly. Preparing your home makes the process easier for the installer and lets you be part of the process. 

You should make sure that the windows that need to be replaced are easily accessible. Remove furniture situated by the windows and remove everything from the window sill. If you have carpets it might be a good idea to cover it with plastic, a window replacement can get messy. 

To find the right installer that can provide you with the right solution can be a very time consuming and tiring job. At GreenMatch, we can help you make this an easy 3-step process.
