    Condensation Between Window Panes in Leicester

    Once the seal has failed, the unit has effectively lost its insulation and the moisture won't clear on its own. Left long-term, the internal spacer stains and eventually damages the surrounding frame. Fitted and diagnosed by our own team across Leicester (LE1–LE5) — never subcontracted.

    Surveys typically within 5 working days.

    How we fix it

    We confirm the moisture is between the panes (not on the room-facing surface), measure the pane, and identify the spacer type. Then we quote a matched-spec replacement unit — no need to touch the frame. New argon-filled A+ rated sealed unit with warm-edge spacer, fitted into the existing frame with fresh glazing tape and re-beaded from the inside. Two-hour job per pane.

    • Glass swap only — the frame and beading are reused
    • Warm-edge argon-filled A+ rated units as standard
    • 10-year guarantee on the new sealed unit
    • Likely causes on Leicester homes: Perimeter edge seal failure allowing humid air into the cavity; Age — most sealed units start failing between 15–20 years old.

    Condensation on the outside vs between the panes

    Internal condensation is one of the most common Leicester enquiries we take, especially on units fitted in the mid-2000s new-build wave. The units are hitting 20 years old and the seals are starting to give. We keep common pane sizes in stock for quick turnaround near Victoria Park.
