Window Repairs & Replacement Windows

From failed seals and stiff hinges to full double glazing upgrades, we’ll assess your uPVC or aluminium windows and recommend the most cost-effective fix.

Common Window Issues We Repair

From minor adjustments to failed sealed units, we carry out practical repairs that extend the life of your windows and improve day-to-day operation.

Failed Double-Glazed Units

Mist or condensation between panes, or reduced insulation. We can replace sealed units while retaining existing frames where suitable.

Handles, Hinges & Locks

Stiff operation, misalignment, or worn hardware. We replace and adjust components to restore smooth, secure closing.

Draughts & Water Ingress

Perished gaskets, poor seals, or movement in the frame. We identify the source and repair to improve weather-tightness.

Sash & Opening Adjustments

Dropped sashes, sticking openings, or poor compression. We realign and tune the window for reliable everyday use.

Repair vs. Replacement — Honest Guidance

Repair First, When It Makes Sense

If frames are sound, targeted repairs and sealed-unit replacements can restore performance at a lower cost and with minimal disruption.

Replace for Long-Term Value

If frames are warped, heavily damaged, or outdated, replacement windows can improve security, energy efficiency, and appearance.

We explain what is failing, what can be repaired, and what replacement would involve — so you can make a confident decision.

Frequently asked questions

Should I repair my window or replace it?

We’ll inspect the frame, glazing and hardware. If the issue is isolated (hinges, handles, locks, seals), a repair is often the most cost-effective option. If the unit has failed, the frame is warped, or performance is poor, replacement windows can deliver better security and energy efficiency.

Do you repair uPVC and aluminium windows?

Yes. We repair and replace both uPVC and aluminium windows, including double glazing units, gaskets, hinges, restrictors and locking mechanisms.

Can you replace just the glass (double glazing unit)?

In many cases, yes. If the frame is sound, we can replace the sealed unit to resolve misting/condensation and improve thermal performance.

Do you cover my area?

We’re based in Windsor and cover Berkshire and nearby areas within around 30 miles, including Maidenhead, Slough, Reading, Bracknell, Ascot, Uxbridge, Guildford, High Wycombe, Watford and London.
