What uPVC sliding patio doors offer homes in Mitcham
Here is what to weigh up if you are considering uPVC sliding patio doors for a home in Mitcham:
Replacing a tired patio door in Mitcham? A uPVC slider usually fits the existing opening, so the job is a straight swap rather than building work.
For a rental or family home in Mitcham, frames that never need painting keep upkeep down to an occasional wipe, which is one reason uPVC sliding patio doors suit tighter budgets.
- uPVC frames never need painting or staining; an occasional wipe with warm soapy water keeps white or foiled finishes looking clean.
- 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.
- 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.

What happens when you order uPVC sliding patio doors in Mitcham?
Surveys in the CR4 district are booked at a time that suits you. After you approve the quote, manufacture is typically 2–4 weeks from survey sign-off; on fitting day the old door comes out, the new frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 1 day for a straight swap in an existing opening.
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.
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.
- 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.
Questions about uPVC sliding patio doors in Mitcham
Can you match other doors and windows in my Mitcham home?
Usually, yes. Most aluminium and uPVC systems come in standard RAL colours and finishes, and we can quote dual colour where the inside and outside need to differ. Bring photos of existing frames to the survey.
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.
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.
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.
