Window restoration cost
Aluminium window frame repairs cost £218on average. Broken frames are repaired by reglazing the frame with putty while cosmetic damages and scratches can be filled and repainted.
Other repairs might include fixing seals, adjusting fittings or replacing glass panes.
Newer aluminium frames have a thermal break, which reduces thermal transfer and improves energy efficiency.
When it comes to window restoration, costs can vary considerably based on various factors:
Size of the window and frame
Extent of the damage
