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.
In Clwyd, we price replacement windows against our guide for Wales, £4,100–£8,300 including VAT, then adjust it once we have surveyed your home. We work across Wrexham, Buckley, Deeside and Colwyn Bay and the rest of the county or region. Planning and building control requirements follow the rules for Wales, and we look into your property's position before a written quote is sent.

Homes in Clwyd
Wrexham has Victorian terraces in red Ruabon brick, alongside interwar and post-war estates. The north coast resorts of Rhyl, Prestatyn and Colwyn Bay have Victorian villas, guest-house terraces and bungalows, while Denbighshire and Flintshire villages use local stone under Welsh slate roofs.
Terraces suit loft conversions and rear extensions, and many need repointing and roof work. Coastal bungalows commonly take loft rooms and window renewal, and stone cottages need lime-based repairs.
The north Wales coast is exposed to wind and salt from the Irish Sea, and the Clwydian hills inland are wetter and colder.
Planning and building rules in Clwyd
Clwyd is in Wales, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
In Wales, replacing windows and doors on a house usually needs no planning permission if the new ones are similar in appearance. Listed buildings, flats and some conservation areas are controlled, so the council should be asked first.
Building Regulations in Wales apply to replacement windows and doors, covering energy performance, ventilation and escape routes. A registered competent person can self-certify the work, or building control inspects it.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
A visit to your home
A free survey comes first. It gives us what we need to price replacement windows properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Your fixed price
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.
Plan and prepare
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Finish and handover
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
What you can expect from us
Frequently asked questions
How do I look after new uPVC or aluminium windows?
Caring for new windows is simple: wash frames and glass with warm soapy water a few times a year, avoiding abrasive cleaners and solvents. Clear the drainage slots at the bottom of the frame so rainwater can escape, and put a drop of light oil on hinges and locking points once a year. Check seals and the sealant around the outside every few years, and replace any that have cracked or shrunk.
Do I need planning permission for new windows?
Planning permission is not usually needed to replace windows with similar ones, but it depends on the size and style of the change, your home's location, whether it is listed or in a conservation area, and which UK nation you live in. Listed buildings normally need consent for any change, and some conservation areas restrict uPVC or new styles. Flats may also need the building owner's approval. We check the position for your property before quoting.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
How long does it take to fit windows in a house?
Fitting replacement windows in a typical 3-bed house usually takes one to two days on site. We take out and fit one window at a time, so each room is weathertight again within an hour or two. Bays, sash windows and homes needing scaffolding take longer. Manufacture comes first: made-to-measure frames typically take a few weeks to arrive after the survey and your order are confirmed.
Do I need planning permission in Clwyd?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Clwyd is in Wales, so Wales's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
