Window Repair

About Our Window Repair Service

Not every window problem requires a full replacement. At Red Lion Windows, we carry out a range of repair services on existing UPVC and aluminium windows that are structurally sound but suffering from common faults. A repair is often significantly more cost-effective than replacement, and many issues that homeowners assume mean a new window are actually straightforward fixes. The most common repair we carry out is sealed unit replacement. When double glazing fails — shown by condensation or misting permanently trapped between the glass panes — the sealed unit itself has broken down. In most cases the frame is still perfectly sound, and we can remove and replace the failed unit with a new energy-efficient sealed unit, restoring your window's performance without the cost of new frames. We also repair or replace window hardware: handles that have become loose or stiff, locking mechanisms that no longer engage properly, hinges that sag or bind, and keep plates that have come loose. Many of these parts can be sourced and fitted quickly, returning a window to full operation without any need for replacement. For windows with minor frame damage — hairline cracks, damaged beads, or perished seals around the frame — we will assess whether remedial repair is practical and cost-effective. Our honest approach means we will tell you clearly when repair makes sense and when a replacement is the better long-term decision.
