Window replacement

​Replacing the windows in your home is a big decision and not something you do very often. However, replacing your windows gives you a fantastic opportunity to upgrade the energy performance or change the appearance of your house. 

Whether you are choosing double-glazed timber windows or triple-glazed aluclad windows there are many options to consider. 


  • Glazing: Double or Triple?
  • Materials: Timber only or aluclad timber?
  • Colours: Keep your current colour or try something new.
  • Opening direction: Should the window or door open to the right or the left?
  • Hinges: Top guided, Side hung or side guided? 
  • Locking type: Normal handle, handle with safety catch or a handle with a key?
  • Glass types: Clear glass... Or one of the many obscure options? 
  • Glazing bars: Do you wish to add a little bit of heritage style to your home?
  • Internal profiles: Softline (contemporary internal look) or a more heritage look?
  • Grooves for window boards: Helps window boards & reveals align evenly.
  • Trickle vents: Do you need a little extra ventilation or not? 

The many options available can be a bit confusing - we know. If you have any questions feel free to contact us online or on the phone.

Planning permission and listed buildings

Before changing your windows, you may need to talk to your local planning officer and you may even have to apply for permission if you want something that is very different from what you currently have. 
In most cases you would be fine to replace your windows without asking. 
If you are in doubt, our experts are always ready to help and guide you through the process - feel free to contact us.
