Draught Proofing for Sash Windows
Draught Proofing – Original timber sash windows bring timeless character to your home—but they’re not always known for energy efficiency. Over time, natural movement, paint build-up, and ageing frames can cause gaps that let in cold air and outside noise.
Invisible protection. Noticeable comfort.
At Cavendish & Cole, we offer specialist draught proofing for sash windows—a discreet, effective upgrade that significantly reduces heat loss, rattling, and external noise while preserving the beauty of your existing joinery.
Whether your home is a Georgian townhouse, a Victorian terrace, or a listed property, we provide a tailored service that respects tradition while improving comfort.
