Replacement windows are new frames and sealed double- or triple-glazed units fitted into your existing openings after the old windows are taken out, improving warmth, security and noise reduction while meeting current building regulations.
Whether you live in one of the larger towns, such as Newport, Isle of Wight, Ryde, Cowes and Sandown, or somewhere quieter in Isle of Wight, the way we handle replacement windows is identical. We survey, agree the specification with you, and confirm a fixed price on paper. Everything is planned under the regulations in force in England, and guide costs in the South East sit at £5,000–£10,000 with VAT.

Housing across Isle of Wight
The island has Victorian seaside villas and terraces in Ryde, Ventnor, Shanklin and Cowes, older cottages in island sandstone and limestone, and thatched roofs in some villages. Post-war bungalows, chalets and newer estates are common around Newport and the larger towns.
Victorian villas often need sash-style windows, render repairs and roof work. Bungalows suit loft conversions and extensions, while coastal properties commonly need roofline, fencing and external decorating renewed more often.
Salt and wind exposure is high on most coasts, and parts of the south, such as the Undercliff near Ventnor, are known for ground movement.
Planning and building rules in Isle of Wight
Each UK nation sets its own consent rules, and Isle of Wight is in England. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
Replacing windows and doors on a house is usually permitted development in England when the new ones look broadly similar to the old. Flats, listed buildings and homes covered by an Article 4 direction can need consent, and conservation areas may limit materials or styles.
Replacement windows and external doors must meet Building Regulations for energy efficiency, ventilation and, on upper floors, escape. The work is either self-certified by an installer registered with a competent person scheme or signed off by building control.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Free site survey
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for replacement windows so the price reflects your home.
Written quote
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Dates and permissions
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Isle of Wight property.
The work itself
The work is carried out to the agreed specification, with floors and furniture protected and the site kept tidy. At the end we clean up, walk through the finished job with you and hand over any certificates.

Questions about replacement windows in Isle of Wight
Who do I deal with during the job?
One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.
What happens on the day the windows are fitted?
On fitting day we lay dust sheets, protect floors and furniture near each window, and then remove the old frame carefully to limit damage to plaster. The new frame is fixed, packed, sealed and glazed, and internal trims and external cills are finished. We take away the old windows and clean the glass before leaving. You only need to clear sills and take down curtains and blinds.
Will new windows stop condensation?
New windows reduce condensation on the glass because the inner pane stays warmer, but they do not remove the moisture in the air that causes it. Modern frames are also more airtight, so ventilation matters more after replacement. We fit trickle vents where regulations require them, and we suggest using extractor fans and opening windows regularly. If walls are damp or mouldy, it is worth looking at ventilation and heating at the same time.
Should I choose uPVC or aluminium windows?
uPVC windows are the lower-cost choice, insulate well and need only occasional cleaning, which suits most houses. Aluminium windows have slimmer frames that let in more light and suit modern homes or large openings, but they cost more. Both come in a wide range of colours and finishes. We usually recommend matching the style and proportions of your home's original windows, especially on period properties.
