Is a uPVC sliding patio door a good fit for your home in Finchley?
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:
The rules for a replacement door in Finchley are checked at survey, and your written quote says which approval route applies to your home.
Planning a door wider than about 3.6 m for your Finchley home? That is beyond the uPVC range, so aluminium or a multi-track system would be the next step.
- 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.
- 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.
How much sun will a door in Finchley get?
Sun angles matter for big glazed doors. Around Finchley, midday sun reaches about 62° in summer and drops to about 15° in winter. That low winter sun is free heat through south-facing glass; high summer sun is easier to shade with a roof overhang, and solar-control glass helps where there is none.

From survey to fitted door in Finchley
We plan the job around your home in Finchley: 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 Hendon or Mill Hill, the same process and prices apply.
Do you need approval in Finchley?
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.
Choosing the specification
- Trims and cills. A matching uPVC cill, add-on trims and internal finishing so the new door sits neatly against existing plaster and brick.
- Handles. Lever or pull handles in white, black, chrome or gold-effect finishes, with a key lock on the outside.
- Foiled colours. Anthracite grey, black, cream or woodgrain foils on one or both faces, for an extra charge.
Questions about uPVC sliding patio doors in Finchley
Do you fit uPVC sliding patio doors in Finchley?
Yes. We survey and fit uPVC sliding patio doors in Finchley and across Greater London, including nearby Hendon and Mill Hill. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
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.
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.
