Why choose uPVC sliding patio doors in Dulwich?
A few practical points decide whether uPVC sliding patio doors suit a particular room and opening:
Where a patio door in Dulwich opens onto a conservatory or narrow side return, a sliding panel avoids the clash a hinged door can have with furniture or a gate.
Replacing a tired patio door in Dulwich? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
- 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.
- Multi-chambered uPVC profiles trap still air inside the frame, so the frame itself insulates well without needing a separate thermal break.
- Steel reinforcement inside the main profiles keeps the frame rigid, holds the locking hardware firmly and stops the sliding panel flexing over the years.
Sunlight, glass and orientation in Dulwich
Because Dulwich sees long summer days (about 16 h 38 min) and short winter ones (about 7 h 50 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.

Rules for uPVC sliding patio doors in England
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.
- Glass. Toughened double glazing as standard, with laminated, obscure or solar-control units available.
- Handles. Lever or pull handles in white, black, chrome or gold-effect finishes, with a key lock on the outside.
Questions about uPVC sliding patio doors in Dulwich
How soon can you survey in Dulwich?
Surveys in the SE21 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.
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.
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.
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.
