Are uPVC sliding patio doors right for your Marlborough 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:
Planning a door wider than about 3.6 m for your Marlborough home? That is beyond the uPVC range, so aluminium or a multi-track system would be the next step.
Replacing a tired patio door in Marlborough? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
- Shoot-bolt or hook locking on the sliding panel, plus anti-lift devices, help stop the panel being lifted or levered out of the frame from outside.
- Compressible gaskets and brush pile seals along the interlock reduce the draughts and rattles that an older patio door with worn seals often suffers from.
- Steel reinforcement inside the main profiles keeps the frame rigid, holds the locking hardware firmly and stops the sliding panel flexing over the years.
Light and sun in Marlborough
In Marlborough the shortest day has roughly 7 h 50 min of daylight and the longest about 16 h 37 min. The noon sun sits near 15° above the horizon in winter and 62° in summer — so glass that faces south collects useful warmth from October to March, while a west-facing door may need solar control to stop it overheating in July.
What should you budget for uPVC sliding patio doors in Marlborough?
Guide prices are the same across Wiltshire: the fitted price depends on the size, system and specification, not your postcode. These figures are for a standard 2.1 m high door, fitted, including VAT and removal of an old door of similar size.
| Overall width | Typical panels | Guide price (fitted, inc VAT) |
|---|---|---|
| 1.8 m | 2 panels | £1,895–£2,295 |
| 2.4 m | 2 panels | £2,195–£2,695 |
| 3.0 m | 2 panels | £2,495–£3,095 |

How fitting works in Marlborough
We plan the job around your home in Marlborough: survey first, then a written quote, then manufacture (typically 2–4 weeks from survey sign-off). The fitting itself usually takes 1 day for a straight swap in an existing opening. If you are in Swindon or Calne, the same process and prices apply.
Do you need approval in Marlborough?
In England, a replacement sliding door is a controlled fitting under the Building Regulations. In an existing home, a door with more than 60% glazing must reach a U-value of 1.4 W/m²K or better (or a Doorset Energy Rating of band C) under Approved Document L, and glass in doors must be safety glazing under Approved Document K. We arrange compliance through a competent person scheme installer or by notifying Building Control, and you receive the certificate.
Which options matter for uPVC sliding patio doors?
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- Handles. Lever or pull handles in white, black, chrome or gold-effect finishes, with a key lock on the outside.
- Glass. Toughened double glazing as standard, with laminated, obscure or solar-control units available.
Questions about uPVC sliding patio doors in Marlborough
Can you match other doors and windows in my Marlborough home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the 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 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.
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.
