Slim sliding doors for London extensions, measured and fitted.
We supply and fit Cortizo COR Vision and COR Vision Plus minimal aluminium sliding doors for rear and side extensions across London. Guide price, fitted, from about £6,750 + VAT for a 3.1 m wide opening with two panels, around 10 to 12 weeks after the drawings are signed.
COR Vision or COR Vision Plus?
COR Vision has a 20 mm central interlock, double glazing, Uw from 1.3 W/m²K and panes up to 2.5 × 3.0 m (320 kg). It suits most rear extensions and is excellent value.
COR Vision Plus has a 25 mm interlock, triple glazing, Uw from 0.9 W/m²K, up to 43 dB acoustic insulation and panes up to 4.0 × 4.0 m (400 kg, 700 kg motorised). Choose it for very large openings or a quieter, warmer room. These are the manufacturer's published values; final values depend on size and glass.
What the price includes
The guide price covers doors up to 2.4 m high with measuring, delivery and fitting by our team. Taller doors, glass corners, pocket walls and hidden floor tracks are priced on the drawing. Your fixed price follows the survey.
How it works
Send the opening: sizes, a few photos or the architect's drawings, by email or through the form. We draw it to the opening and send a fixed price, usually within 48 hours. We then measure on site and you sign the workshop drawings before anything is made. After manufacture we deliver and fit, and leave the site clean.

Questions we are asked
How much do slimline sliding doors cost in London?
Our guide price is from about £6,750 + VAT (£8,100 including VAT) fitted for a 3.1 m wide, 2-panel Cortizo COR Vision door up to 2.4 m high. Larger openings, COR Vision Plus and glass corners cost more and are priced on the drawing.
How long do slim sliding doors take?
Around 10 to 12 weeks from the day the workshop drawings are signed. Order them so they arrive when the roof is on; our timeline calculator works this out from your build start date.
Do you only supply, or also fit?
We measure, supply and fit as one job. Supply only is possible for contractors who install themselves.
Can the track be hidden in the floor?
Yes. The COR Vision frame can be concealed in the floor, walls and ceiling for a flush threshold. Your builder prepares the floor build-up to our drawing.
Which areas do you cover?
All of London, with most work in West and South-West London, plus Surrey, Hertfordshire and Buckinghamshire.
