Local housing and replacement windows

Newport has Victorian and Edwardian terraces and interwar suburbs, while valley towns such as Ebbw Vale, Abertillery and Blaenavon have stone terraces stepped along steep hillsides. Monmouth and Abergavenny keep Georgian centres, and Cwmbran was built as a post-war new town with planned estates.

Valley terraces commonly need repointing, roof work and window replacement, and steep plots can make extensions more involved. Newport terraces suit loft rooms, while Cwmbran homes often take garage conversions and cladding upgrades.

If your house in Cwmbran fits one of these patterns, it helps us anticipate what replacement windows will involve, though we always confirm the details on site.

Planning and building rules in Cwmbran

Because Cwmbran falls under Wales's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.

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.

How does the job run?

  1. A visit to your home

    We begin by looking at the job in person. During the free survey we discuss options, materials and budget for replacement windows, and photograph or measure anything the quote needs to reflect.

  2. Price and scope agreed

    You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for replacement windows.

  3. Dates and permissions

    Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.

  4. Build and hand over

    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.

Frequently asked questions

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.

What happens at the survey?

We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from replacement windows, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.

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.

Do I need planning permission in Cwmbran?

It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Cwmbran 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.

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.
