Care & Maintenance

Welcome to your comfort zone

 Congratulations on your new uPVC, double glazed windows and doors. We know you will get the most out of your windows and doors, and enjoy lifelong comfort and energy savings. Although they are very low maintenance, here are a few useful tips for ongoing care.

How to look after your Thermotek windows and doors

 Cleaning your glass:

 Use soap and water to remove any external grime. For a better finish, use a household window cleaner and a soft cloth on your glass. Please take care if you are wearing jewellery. Special non-scratch glass wipers are also available to clean your glass.

 Cleaning your uPVC frame:

 For general upkeep, clean the profile of your window frame every 4 to 6 months with warm water and mild detergent. Use a non-abrasive detergent and soft cloth.


 Thermotek windows and doors have inbuilt drainage vents. To ensure they continue to be efficient, clear the dirt and leaves from the drainage vents. Clear holes and check drainage by flushing it through with some clean water.


 Our windows and doors come with multi-point locking systems and steel reinforced frames. This ensures extra security in your home. We recommend still taking all sensible precautions at all times:

  • Lock all doors and windows before you leave home.
  • Lock windows and remove keys, keeping them out of external view.
  • Ensure keys are accessible to household members in the event of an emergency.
