Are uPVC sliding patio doors right for your Llantrisant home?
The right door depends on the opening, the room and the way you use the garden. Here is how uPVC sliding patio doors tend to work out in practice:
Replacing a tired patio door in Llantrisant? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
Where a patio door in Llantrisant opens onto a conservatory or narrow side return, a sliding panel avoids the clash a hinged door can have with furniture or a gate.
- uPVC frames never need painting or staining; an occasional wipe with warm soapy water keeps white or foiled finishes looking clean.
- Woodgrain and colour foils, including anthracite grey and black, let a uPVC door match existing windows instead of appearing as a white frame on a coloured elevation.
- Multi-chambered uPVC profiles trap still air inside the frame, so the frame itself insulates well without needing a separate thermal break.

Finishes and extras for uPVC sliding patio doors
- Handles. Lever or pull handles in white, black, chrome or gold-effect finishes, with a key lock on the outside.
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
- Trims and cills. A matching uPVC cill, add-on trims and internal finishing so the new door sits neatly against existing plaster and brick.
Questions about uPVC sliding patio doors in Llantrisant
Do you fit uPVC sliding patio doors in Llantrisant?
Yes. We survey and fit uPVC sliding patio doors in Llantrisant and across Mid Glamorgan, including nearby Pontypridd and Cowbridge. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
How much do uPVC sliding patio doors cost?
uPVC sliding patio doors start from a guide price of £1,695 for a 1.5 m two-panel door, fitted, inc VAT, at standard 2.1 m height. A 2.4 m door is a guide £2,195–£2,695, and a 3.6 m three-panel door is around £2,895. Coloured foils, glass upgrades and a low threshold move the figure up, and the final price is fixed in a written quote after survey.
What sizes do uPVC sliding doors come in?
uPVC sliding doors are made to measure, so they come in any size within the system limits rather than set sizes. Our uPVC range covers overall widths from about 1.5 m to 3.6 m at standard 2.1 m height. Two panels cover most openings up to about 3 m, and beyond that a third panel is added. For larger openings, aluminium carries bigger panels.
How do I maintain a uPVC sliding door?
A uPVC sliding door needs only light maintenance: wipe the frames with warm soapy water, avoid abrasive cleaners that dull the surface, and vacuum the track so grit does not wear the rollers. Lubricate the lock keeps and handle mechanism once a year. If the panel drags, the rollers can usually be adjusted rather than replaced. Check the drainage slots in the outer frame after autumn leaf fall, as blocked slots let water sit in the track.
