Regardless of the window type (sash windows or casements) a solution can be found for any type of damage or defect.

Wood treatments When timber frames suffer deterioration such as corrosion or swelling, it may seem impossible to repair; however, a professional can apply the latest techniques and products in order to save original wooden structures. Most commonly, wood resins are used towards repairing mild to moderate damage. Also, chemicals such as disodium octaborate may be applied to eliminate decay factors such as fungus.

Part replacements

Although owners ideally want to save entire original windows, when certain parts are irreparably damaged, there is no need to discard the whole structure. The damaged parts can therefore be removed and replaced with new identical ones, emulating the appearance of the old ones to the highest extent as to successfully match the rest of the window. Any parts can be replaced without diminishing the character provided by authentic windows.


Considering the fact that in previous centuries durable glass was very expensive, many historic properties nowadays feature antique windows which incorporate thin, brittle glass panes. Although valuable due to its age, this glass can easily be damaged. Re-glazing an old window is perfectly feasible however, and even adapting it to modern standards such as double glazing.


Painting an old window frame is definitely a job requiring finesse and experience, which is why it is advisable for it to be carried out professionally. Whereas the practical importance of properly painting sash windows is widely known, casement windows sometimes feature intricate metallic grids which require meticulous work.
