Window Replacement FAQs
How do I know if I need to repair or replace my windows?
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.
Do I need planning permission to replace my windows?
For most standard residential properties, replacing like-for-like windows doesn’t require planning permission under permitted development rights. Conservation areas and listed buildings are exceptions.
How long does window replacement take?
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.
What window style is best for my property?
It depends on your home’s age and character. Flush sash windows suit period properties; casement and tilt & turn work well in modern homes; bay and bow windows are a classic choice for the Victorian and Edwardian houses common across Southampton.
Are your replacement windows energy efficient?
Yes. Our Liniar uPVC windows feature a thermal profile designed to minimise heat loss and achieve excellent energy ratings.
