What aluminium sliding doors offer homes in Redhill
These are the points a surveyor will go through with you when you choose aluminium sliding doors for a home in Redhill:
If your Redhill home has a rear extension or kitchen-diner, aluminium sliding doors let you place a table close to the glass, because no panel swings into the room.
For a south- or west-facing garden in Redhill, solar-control glass in the sliding panels can keep a glazed room more comfortable on summer afternoons.
- Brush and gasket weather seals along every meeting edge, together with drainage slots in the outer track, carry rainwater away instead of letting it collect against the panels.
- Aluminium is stiff enough to carry wide panels without bowing, which keeps the number of vertical frames low even across openings of four, five or six metres.
- Multi-point hook locks grip the frame at several points along the closing edge, while anti-lift blocks stop a shut panel being raised off its track from outside.
Daylight in Redhill and what it means for your glass
At the latitude of Redhill, the midday sun climbs to about 62° in late June but only about 15° in late December, when daylight lasts around 7 h 52 min against 16 h 35 min in midsummer. A south-facing aluminium sliding door lets that low winter sun deep into the room; on a west or south elevation, solar-control glass keeps summer afternoons comfortable.

Timescales for aluminium sliding doors in Redhill
A surveyor visits your Redhill home to measure the structural opening, check levels and the lintel, and talk through glass and finish. Once you confirm the written specification, the door is made to measure — typically 4–6 weeks from survey sign-off — and fitting usually takes 1 day for a two-panel straight swap; 1–2 days for larger doors. We also cover Reigate (2 km west) and Horley (7 km south).
Rules for aluminium sliding 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.
Finishes and extras for aluminium sliding doors
- Threshold. A standard or low threshold, or a flush finish with a drainage channel outside where floor levels allow.
- Dual colour. A different colour inside and outside, so the exterior can match your windows while the interior suits the room.
- Panel configuration. Two, three or four panels, with the sliding panel on the left, right or both sides to suit how you use the room.
Questions about aluminium sliding doors in Redhill
Do you fit aluminium sliding doors in Redhill?
Yes. We survey and fit aluminium sliding doors in Redhill and across Surrey, including nearby Reigate and Horley. Start with a guide price online or call us, and we will arrange a free survey for a new or replacement door.
How do you look after aluminium sliding doors?
Aluminium sliding doors need little care: wash the frames with mild soapy water a few times a year, vacuum grit out of the bottom track and keep the drainage slots clear. A light silicone spray on the locking points once a year keeps them smooth, and rollers can be adjusted if a panel starts to drag. Manufacturer guarantees on frames, hardware and sealed units are passed to you, and our workmanship guarantee is set out in writing in your quote.
How long do aluminium sliding doors take to arrive?
Aluminium sliding doors typically take 4–6 weeks to make after you sign off the surveyed specification, because each door is built to measure and powder coated to order. Fitting a straight swap of a two-panel door typically takes 1 day, and larger doors 1–2 days. These are typical times rather than promises, and we confirm a date once the order is placed.
Do aluminium sliding doors need Building Regulations approval?
In England, replacement sliding doors are controlled fittings, so the work is either carried out by an installer registered with a competent person scheme, who self-certifies and notifies, or notified to Building Control. The glass must be safety glazing to BS EN 12600. Forming or widening an opening is structural work needing its own application and calculations. Wales, Scotland and Northern Ireland have their own rules.
