White uPVC windows in County Down
uPVC no longer means white only. Frames can be foiled in woodgrain or solid colours such as grey, black or cream, often outside only with white inside. Foils are bonded at the factory and should be cleaned with a soft cloth and mild detergent, because abrasive pads and solvents mark the surface.
The price of uPVC windows depends mainly on size, the number of opening sashes, frame colour, glass specification and hardware. Bay windows, openings that need a tower or scaffold, and difficult removal of old frames add labour. See the guide prices for typical ranges; your written quote fixes the exact figure.
Windows are replaced room by room, so each opening is only exposed for a short spell. A single window is usually changed within a day, and a typical house takes a few days depending on the number of windows, bays and access. Inside, reveals are finished with trims, sealant or filler.
Bay windows need extra care. Some older bays carry load from the wall or roof above, so the glazier checks the support before removal and may fit bay poles or ask for structural advice. Replacing a window in the same opening is different from widening it, which needs a new lintel.

What applies in County Down
Technical Booklet V covers safety glazing in Northern Ireland, including glass in and around doors and low-level glazing where people could walk into it.
Replacement windows on houses in Northern Ireland are often permitted development, but conservation areas and listed buildings can need consent. Check with the council's planning office.
County Down has its own coastline, so for homes and businesses near the sea, salt air and wind-driven rain are part of the brief. Near the coast, salt spray and wind-driven rain test seals, drainage and hardware. uPVC itself does not corrode, but stainless or coated locking parts, well-sealed joints around the frame and clear drainage slots matter, and exposed elevations may need frames with higher weather ratings.
Older rural cottages often have irregular openings, thick walls and timber lintels, so every frame is measured individually and the support above each opening is checked. Exposed hillside and open-field sites benefit from reinforced frames and careful sealing against driving rain.

Choosing your uPVC windows
Georgian or astragal bars
Bars set between the panes or applied to the faces of the glass for a traditional divided-pane look.
uPVC sliding sash
Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.
Obscure and acoustic glass
Patterned or satin glass for bathrooms and street-facing rooms, and laminated acoustic glass to reduce traffic noise.
Double or triple glazing
Low-E double glazing suits most homes; triple glazing adds a third pane for lower heat loss and quieter rooms, but units are heavier.
uPVC Windows in County Down: questions
What guarantee comes with new uPVC windows?
Manufacturer guarantees apply to new frames, sealed units and hardware, and the terms are confirmed in writing. Guarantee terms for the installation are set out in writing with your quote, so you know what is covered and for how long before you commit. Keep this paperwork with your building regulations certificate, because buyers' solicitors usually ask for both.
How long does it take to fit uPVC windows?
Most single windows are changed within a day, and a typical house usually takes a few days. Bays, large picture windows and openings that need a tower or scaffold take longer. Manufacturing comes first, because every frame is made to the survey measurements, and the lead time is confirmed with your quote.
Will fitting new windows damage my plaster or decor?
Some disturbance is normal, but it is usually limited to the edges of each opening. The glazier cuts out the old frame, fits the new one and finishes the inside with trims, sealant or filler. Older frames set deep into plaster may need some plaster repair, and we flag that at survey so it is covered in the quote.
How much do uPVC windows cost?
The cost of uPVC windows depends on the size and number of windows, how many sashes open, the frame colour, the glass and the access. White casements with standard double glazing sit at the lower end, while foiled colours, triple glazing and bay windows cost more. See the guide prices for typical ranges; the written quote fixes the price for your specification.
