Replacement Window Options

uPVC Windows

Our uPVC windows are manufactured using the Liniar profile system — one of the UK’s most thermally efficient window systems. Available in casement, bay and bow, flush sash, tilt-and-turn, French and bi-folding styles.

Aluminium Windows

For a slimmer, more contemporary look, aluminium windows offer narrow sightlines and excellent strength — ideal for modern homes, extensions and commercial properties.

Frequently Asked Questions — Window Replacement Southampton

If the frames are structurally sound and only one or two units have misted, repair is usually the better option. If the frames are warped, damaged or more than 25–30 years old, full replacement is likely more cost-effective and will deliver significantly better energy performance.
For most standard residential properties, replacing like-for-like windows does not require planning permission under permitted development rights. Conservation areas and listed buildings are exceptions.
Most homes can have all windows replaced within one to two days. Rooms are left secure and weathertight at the end of each working day.
This depends on the age and character of your home. Flush sash windows suit period properties; casement and tilt-and-turn work well in modern homes; bay and bow windows are a classic choice for the Victorian and Edwardian houses common across Southampton.
Yes. Our Liniar uPVC windows feature a thermal profile designed to minimise heat loss and achieve excellent energy ratings. Replacing old windows with modern units can make a noticeable difference to comfort and heating costs.
