Are uPVC sliding patio doors right for your Melksham home?
A few practical points decide whether uPVC sliding patio doors suit a particular room and opening:
Planning a door wider than about 3.6 m for your Melksham home? That is beyond the uPVC range, so aluminium or a multi-track system would be the next step.
Where a patio door in Melksham 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.
- 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.
- As the least expensive sliding door material, uPVC lets you replace a draughty older patio door with modern double glazing on a modest budget.
Daylight in Melksham and what it means for your glass
Daylight in Melksham runs from about 7 h 51 min in December to 16 h 37 min in June, with the noon sun at roughly 15° and 62° respectively. Use that to choose your glass: standard low-E double glazing for north and east elevations, and consider solar-control or triple glazing for sunny south and west walls.
How much do uPVC sliding patio doors cost in Melksham?
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) |
|---|---|---|
| 1.5 m | 2 panels | £1,695–£2,095 |
| 2.1 m | 2 panels | £1,995–£2,495 |
| 3.6 m | 3 panels | £2,895–£3,495 |

Survey, manufacture and fitting around Melksham
We plan the job around your home in Melksham: 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 Corsham or Trowbridge, the same process and prices apply.
Do you need approval in Melksham?
English Building Regulations treat a new or replacement external door in an existing home as a controlled fitting: it needs a U-value of 1.4 W/m²K or better (or Doorset Energy Rating band C) if more than 60% of it is glazed (Approved Document L), and safety glass in a critical location (Approved Document K). Compliance is arranged through a competent person scheme installer or a Building Control notification, so you get a certificate for your records.
Which options matter for uPVC sliding patio doors?
- Panel layout. Choose which side slides, or a three-panel layout for openings beyond about 3 m.
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
- 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 Melksham
Do you fit uPVC sliding patio doors in Melksham?
Yes. We survey and fit uPVC sliding patio doors in Melksham and across Wiltshire, including nearby Corsham and Trowbridge. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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 quickly can a uPVC patio door be fitted?
A uPVC sliding patio door is typically made in 2–4 weeks after you sign off the surveyed specification, the shortest lead time of the sliding door materials. A straight swap in the same opening typically takes 1 day, including removing the old door, fitting, sealing and making good inside. Times are typical rather than promised, and foiled colours can add a little time.
Do I need permission to replace a patio door with a uPVC slider?
In England, replacing a patio door on a house is usually permitted development if the new door looks similar, though flats, listed buildings and Article 4 areas may need consent. The work must be done by a competent person scheme installer or notified to Building Control, and the glass must be safety glazing. Wales, Scotland and Northern Ireland have their own planning and building rules.
