Sash Window Draught-Proofing in Market Harborough

The biggest complaint about original sash windows is draughts — and it is also the most fixable. Draught-proofing seals the gaps that let cold air in and warm air out, stops the rattles, and makes period windows far more comfortable without changing how they look. We connect you with a local craftsman who fits proper draught-proofing systems, and slim double glazing where suitable.

What the service includes

• A survey of the windows and where they are losing heat
• A discreet draught-proofing system fitted into the sashes
• Easing and adjusting the sashes so they seal and slide well
• Optional slim double-glazed units in existing or new sashes
• Advice on any conservation-area considerations

Why it works

Most of the heat loss and cold draughts from a sash window come through the gaps around the moving sashes, not through the glass itself. A brush-seal draught-proofing system, routed discreetly into the frames, closes those gaps while still letting the windows open and close smoothly. The result is a warmer room, no rattles, and lower heating bills — with the character untouched.

Adding double glazing

Where more warmth is wanted, slim double-glazed units can be fitted into many sash windows, either into the existing sashes or into new sashes made to match. This brings insulation close to modern standards while keeping the period look — though in conservation areas it is worth checking what is permitted, which the craftsman can advise on.

Local knowledge

With so many period and conservation-area homes around Market Harborough and the Welland valley, draught-proofing is often the ideal upgrade: it delivers modern comfort while respecting windows that replacement would not be permitted, or would spoil.
