Why VIONA
Built for comfort. Fitted with care.
New windows and doors should make a difference you can feel from the very first night. We combine high-performance frames and glazing with careful, tidy installation, so your home stays warmer, quieter and more secure for decades.
Warmer rooms
Multi-chambered frames and energy-rated glazing hold on to heat and stop draughts, so your heating has less work to do.
Quieter living
Sealed glass units and tight compression gaskets soften the sound of traffic, rain and busy streets.
Secure by design
Multi-point locks, internal beading and anti-snap cylinders come as standard on every installation.
Easy to look after
No sanding and no painting. A wipe with warm soapy water keeps frames looking like new for years.

Our old sashes rattled all winter. The new ones look exactly right for the house, glide beautifully and the front rooms are finally warm.

FAQ
Questions we're often asked
Can't find what you're looking for? Send us a message with your quote request and we'll get back to you.
How much do new UPVC windows cost?
Every home is different, so prices depend on the size, style, glazing and finish of each window. We measure every opening during a free home survey and then send you a clear, itemised quote with no hidden extras.
How long does installation take?
A typical house of windows takes one to two days, a front door usually half a day, and a conservatory between one and three weeks depending on its size and groundwork. We confirm a firm schedule with you before work starts.
Are UPVC windows energy efficient?
Yes. Modern UPVC frames are multi-chambered to trap heat, and combined with energy-rated double or triple glazing they significantly reduce heat loss and draughts compared with older single-glazed or worn units.
Will my new windows and doors be secure?
Every window and door we fit has multi-point locking, internally beaded glass that cannot be removed from outside and key-lockable handles. Our front doors also use anti-snap, anti-bump cylinders.
Can I choose colours other than white?
Absolutely. Choose from smooth colours such as anthracite grey, black and cream, or realistic woodgrain finishes like golden oak and rosewood, on the outside, the inside or both.
What guarantee do you offer?
Frames, sealed glass units and hardware are covered by a 10-year guarantee, and we stand behind our installation work too. Full details are included with every quote.
Do you take away the old windows?
Yes. We remove your old frames and glass, recycle them wherever possible, and leave your home clean and tidy at the end of every working day.
