Calne: uPVC casement windows
uPVC frames need washing a few times a year with warm soapy water and a drop of light oil on hinges and locking points. Drainage slots along the bottom of the outer frame let rainwater escape, so keep them clear of dirt and leaves to stop water collecting in the cill.
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.
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.

- Coast
- Calne is well inland, around 46 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Calne the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. uPVC frames are bulkier than aluminium, so they take a little more glass area from small windows. On south and west elevations, solar-control or neutral low-E glass limits overheating, while north-facing rooms benefit from high light-transmission glass and warm-edge spacers that reduce condensation.
- Access and setting
- 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.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Approved Document L sets the minimum energy performance for replacement windows and doors in existing homes in England: a U-value of 1.4 W/m²K, or Window Energy Rating band B for windows; doors can instead meet a Door Set Energy Rating (band B, or band C for doors more than 60% glazed); rooflights need 2.2 W/m²K.
What you can choose
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 sliding sash
Vertical sliders that mimic traditional box sashes, using spring balances instead of weights, where planning rules allow uPVC.
Casement windows
Side-hung or top-hung sashes on friction hinges, suiting most houses, with easy-clean hinges that let upper-floor glass be cleaned from inside.
uPVC Windows in Calne: questions
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.
Can I fit uPVC windows myself?
You can, but the work still has to meet building regulations. In England and Wales, without an installer registered with a competent person scheme you need building control approval and inspection. Accurate measuring, correct packing, fixing and sealing all affect weather performance and how the locks work, and mistakes are hard to put right because frames are made to size and cannot be returned.
Are uPVC windows secure?
Modern uPVC windows can be very secure when they have multi-point locks, internal glazing beads, key-locking handles and laminated glass where needed. PAS 24 is the security standard expected for easily accessible windows in new homes in England. Ask for ground-floor windows tested to it, and avoid frames where the glass is beaded from outside.
Do I need building regulations approval for replacement uPVC windows?
Yes. In England, replacement windows are controlled fittings, so the work must meet building regulations. An installer registered with a competent person scheme such as FENSA or Certass can self-certify the work and you receive a certificate; otherwise approval comes from building control. Wales, Scotland and Northern Ireland run their own systems, and we explain which route applies before work starts.
