Sealed Unit Replacement

If your windows are misted, foggy or cloudy we can replace the sealed unit saving you £££'s compared to replacing the whole window!

Once your sealed units have blown (misted, foggy or cloudy) they don’t just look unsightly they’re now hugely underperforming. Blown sealed units no longer give you the full benefits of double glazing, typically Argon gas will be used between the panes of glass creating a thermal barrier between the cold outside and your warm air inside, once the sealed unit has blown this disappears leaving you with little or no thermal protection.

Placing an order is EASY

We believe in making things simple, that's why we've created a FIXED pricing structure so you know exactly how much your replacement units will cost.
Do I have Fanlights or Casement Windows?

Please refer to the window illustration to determine if you have Fanlights that need replacing or Casements or a mixture of both!

Solar Control Glass

If you have rooms that over heat because they attract a lot of sun we have the perfect solution.

Solar Control Glass works by deflecting the heat from the sun away from your window, keeping you cooler in summer.

Annealed, Tempered or Laminated?

Different types of glass for different applications. With years of experience in the industry we can advise you accordingly on the best type of glass for your needs.

Annealed glass is typically used for most windows (windows cannot be within 800mm from the floor level), Toughened glass is generally used for Front & Back Doors, Full Height Windows, French Doors, Bi Folding Doors and Patio Sliding Doors etc to conform to building regulations.
