Stay Warm
Repairing your windows and doors is one of the most effective ways to save on heating bills and keep your home warm. Faulty hinges, broken seals, or worn-out locks can cause draughts and heat loss, forcing your heating system to work harder and increasing energy costs.
By fixing these issues, you can restore the airtight seal of your windows and doors, preventing cold air from entering and warm air from escaping.
Upgrading to energy-efficient double glazing or replacing existing glass units can further improve insulation, reducing heat loss significantly.
These simple repairs not only lower your energy bills but also make your home more comfortable during colder months.
