Grantham: uPVC casement windows
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.
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.
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.
When windows are replaced in England, Approved Document F expects the room's ventilation to be no worse than before. That usually means trickle vents in the head of the new frames, sized to the room, so the glazier records whether the old windows had vents and specifies the new ones to suit.

Grantham at a glance

- NG31 and the surrounding area, including Sleaford, Newark-on-Trent and Melton Mowbray
- Coast
- Grantham is well inland, around 44 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Grantham the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.3 hours of daylight, rising to about 60° and 16.7 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 Q applies to new homes in England, where doors and windows are expected to meet PAS 24 or an equivalent standard. It does not apply to replacements in existing homes, but PAS 24 products are still a sensible choice.
Specification choices
Tilt and turn
Opens inwards from the side for cleaning or escape, or tilts from the top for secure ventilation; practical for flats and upper floors.
Woodgrain and colour foils
Grey, black, cream or woodgrain foils on one or both faces, so the frames can match a door or suit an older house.
Georgian or astragal bars
Bars set between the panes or applied to the faces of the glass for a traditional divided-pane look.
uPVC Windows in Grantham: questions
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.
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.
Should I choose double or triple glazing?
Well-specified double glazing with low-E glass and warm-edge spacers can meet the energy standard for replacement windows, and the certified rating confirms it. Triple glazing adds a third pane, which helps on cold, noisy or north-facing elevations, but the units are heavier and need frames designed for them. We can quote both so you can compare.
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.
