    Draughty Windows in Leicester

    A single draughty window can add £40–£70 a year to a modest gas bill and pulls warm moist air past the frame, which is where black mould usually starts on the reveal. Fitted and diagnosed by our own team across Leicester (LE1–LE5) — never subcontracted.

    Why your windows are draughty (and what fixes it)

    If you're in Leicester (LE1–LE5) and you can feel a cold draught coming off your windows, you're not imagining it — and it's not something you have to live with. Most of the Leicester homes we quote for draught issues sit inside a 15-year replacement window on the original PVCu, or they're original timber sashes near Victoria Park that have simply dried out over three winters. Both are fixable.

    Symptoms we hear from Leicester customers

    • Curtains move when the window is shut
    • Cold spot you can feel a foot away from the frame
    • Whistling sound in wind above 20mph
    • Condensation puddling on the inside sill in the morning
    • Rising heating bills without a thermostat change

    How we fix it

    We do a smoke-pencil test around the sash on survey — it shows exactly where the air is entering, so we can tell you whether it's a £65 gasket refresh or a full frame swap before you commit. For frames under 15 years old we usually re-gasket, re-adjust the hinges and refit the sashes — a two-hour job per window. For older PVCu or original timber we recommend an A+ rated flush casement replacement with double weather seals as standard.

    • Smoke-pencil survey included free — you'll see where the draught is
    • A+ rated replacements as standard, 10-year insurance-backed guarantee
    • Repairs where a repair genuinely fixes it — we won't sell a full unit if a £65 gasket works
    • Likely causes on Leicester homes: Perished rubber gaskets on 15+ year old PVCu frames; Dropped sash on a friction-hinge window pulling the seal off the frame.
