Replacing a tired patio door in Northumberland? 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.
- Steel reinforcement inside the main profiles keeps the frame rigid, holds the locking hardware firmly and stops the sliding panel flexing over the years.
- 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.

Daylight and glass in Northumberland
At the latitude of Northumberland, the midday sun climbs to about 58° in late June but only about 11° in late December, when daylight lasts around 7 h 07 min against 17 h 25 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.

Approvals 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.
Questions about uPVC sliding patio doors in Northumberland
Do I need building approval for uPVC sliding patio doors in Northumberland?
In England a replacement door is a controlled fitting, so compliance is arranged through a competent person scheme installer or Building Control; new openings need a Building Regulations application. We confirm the right route for your property at survey, so the paperwork is in place before fitting.
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.
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.
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.
