Sealed Unit Replacement

A sealed unit replacement involves replacing only the glass unit (the double or triple glazed pane) within your existing window frame. This is a cost-effective solution if your frames are still in good condition but the glass is misted, cracked, or has lost its thermal efficiency.

Common signs include condensation or misting between the glass panes, visible cracks or chips, drafts, or a noticeable increase in your energy bills due to poor insulation. If you see moisture trapped inside your double glazing, it's definitely time for a replacement.

Not necessarily! If your window frames (PVC, timber, or aluminium) are still structurally sound and in good condition, we can often replace just the sealed glass unit. This saves you money, reduces waste, and minimizes disruption compared to a full window replacement.

We offer a wide range of glass types, including standard double glazing, triple glazing for superior insulation, privacy/frosted glass, self-cleaning glass, thermally efficient (Low-E) glass, toughened safety glass, solar control glass, and tinted glass. We can help you choose the best option for your needs.

The time taken can vary depending on the number and size of units being replaced. Typically, once the new units are manufactured (which can take 1-2 weeks), the installation itself is quick, often completed within a few hours per window with minimal disruption to your home.
