These ironmongery pieces must be maintained and cleaned to appreciate their exquisite design.

Timber windows require careful maintenance to keep them in good condition. Inattention to maintenance routinely could result in:

Sashes that do not slide easily.

Holes in the frame which allow water to get in and cause decay and damage.
