Regularly Asked Questions (FAQ)

1. Can rotten sash windows actually be conserved?

In the huge majority of cases, yes. Even when lumber appears significantly decomposed, a professional can generally change the rotten areas (such as the sills or bottom rails) while keeping the original frame and upper sashes undamaged.

4. For how long does the repair procedure take?

Typically, a single window can be fully brought back and draught-proofed within one to two days, though larger tasks involving multiple windows or substantial rot may take longer.
