Are uPVC sliding patio doors right for your Morden 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:
Where a patio door in Morden 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 Morden? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
- 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.
- 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 Morden
At the latitude of Morden, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 51 min against 16 h 37 min in midsummer. A south-facing uPVC sliding patio door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

How fitting works in Morden
Once the opening is measured, nothing is ordered until you sign off the specification. Lead time is typically 2–4 weeks from survey sign-off. Our fitters protect floors, remove the old door, install and seal the new one and leave the area clean — usually 1 day for a straight swap in an existing opening for a door like this.
Do you need approval in Morden?
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?
- Glass. Toughened double glazing as standard, with laminated, obscure or solar-control units available.
- Trims and cills. A matching uPVC cill, add-on trims and internal finishing so the new door sits neatly against existing plaster and brick.
- Threshold. A standard threshold for a straight swap, or a lower threshold where the floor build-up allows.
Questions about uPVC sliding patio doors in Morden
How soon can you survey in Morden?
Surveys in the SM4 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 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.
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.
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.
