Are uPVC sliding patio doors right for your Southall home?
Most homeowners choosing uPVC sliding patio doors want the same things: more light, a clear view and a door that is easy to live with.
Planning a door wider than about 3.6 m for your Southall 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 Southall? 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.
- As the least expensive sliding door material, uPVC lets you replace a draughty older patio door with modern double glazing on a modest budget.
- A two-panel uPVC slider usually fits the same opening as an old patio door, so a straight swap avoids building work and typically takes a day.

How fitting works in Southall
Here is the usual sequence in Southall: guide price, free survey, written quote, then manufacture (typically 2–4 weeks from survey sign-off). Fitting typically takes 1 day for a straight swap in an existing opening. Nearby, we also survey in Hayes, Ealing and Hounslow.
Do you need approval in Southall?
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.
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.
- 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 Southall
How soon can you survey in Southall?
Surveys in the UB1 district are booked at a time that suits you, and we offer survey dates when we reply to your enquiry. After you approve the written quote, manufacture is typically 2–4 weeks from survey sign-off.
Are uPVC sliding doors secure?
uPVC sliding doors are secure when the sliding panel has multi-point locking, anti-lift protection and steel reinforcement in the frame. Systems are available tested to PAS 24, the UK enhanced security standard for doorsets. Laminated glass adds resistance to breaking through, and a key-locking handle stops the door being opened from inside if a pane is broken.
Should I choose uPVC or aluminium for a sliding door?
Choose uPVC if budget and a quick, simple replacement matter most, and aluminium if you want slimmer frames, bigger panels or a powder-coated colour. uPVC insulates well and costs less, but its frames are wider and its panels smaller. Aluminium suits openings over about 3.6 m and modern extensions. Our aluminium vs uPVC guide sets out the differences.
Are uPVC sliding doors energy efficient?
uPVC sliding doors are energy efficient because the plastic frame conducts little heat, with whole-door U-values typically around 1.3–1.6 W/m²K double glazed, depending on profile and glass. In England, a replacement door in an existing home with more than 60% glazing must achieve 1.4 W/m²K or better, so the sealed unit is specified to meet it. Wales, Scotland and Northern Ireland set their own energy requirements.
