Is a sliding door for a new opening a good fit for your home in Cranleigh?
The right door depends on the opening, the room and the way you use the garden. Here is how sliding doors for new openings tend to work out in practice:
Where a Cranleigh house has a bay, chimney breast or upstairs window directly above the planned opening, the engineer will need to account for it in the steel design.
Thinking about a wider opening in Cranleigh but unsure of the size? Mark it out on the wall inside and out with tape, then picture the furniture and the view before you decide.
- Temporary propping holds up the wall above while the masonry is cut out, keeping floors, ceilings and the roof safely supported throughout the work.
- Structural calculations are included in the guide price, and the Building Regulations application is handled as part of the project, so you are not left coordinating engineers and inspectors.
- The door is measured from the finished opening rather than from drawings, so it fits the opening as built, not as it was intended to be built.
Planning glass for the light in Cranleigh
Because Cranleigh sees long summer days (about 16 h 34 min) and short winter ones (about 7 h 53 min), the elevation your door faces makes a real difference. With the midday sun at about 15° in winter, a south-facing door brings light well into the room; a west-facing door catches hot late-afternoon sun in summer.
How much do sliding doors for new openings cost in Cranleigh?

Timescales for sliding doors for new openings in Cranleigh
Nothing is ordered until you sign off the surveyed specification. The door is made from the finished opening sizes (typically 4–6 weeks for the door after the opening is measured; building work scheduled around approvals), and fitting usually takes 3–5 days of building work, then 1–2 days to fit the door. If you are in Godalming or Guildford, the same process and prices apply.
Rules for sliding doors for new openings in England
In England, forming or widening an opening is structural work that needs a Building Regulations application, structural calculations and usually a steel beam on padstones. The new door is also a controlled fitting (U-value 1.4 W/m²K or better if more than 60% glazed). If steelwork bears on a party wall, the Party Wall etc. Act 1996 may apply.
Options to consider for your sliding door for a new opening
- Temporary door or boarding. A secure, weathertight closure while the made-to-measure door is being manufactured.
- Concealed steel. Setting the beam so it sits above the ceiling line, giving a cleaner head detail inside.
- Low threshold detail. Adjusting floor and outside levels during the building work to allow a lower sill.
Questions about sliding doors for new openings in Cranleigh
Can you match other doors and windows in my Cranleigh 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.
How much does it cost to widen an opening for sliding doors?
Our guide price for forming or widening an opening is £3,595 for 2.4 m and £4,495 for 4.8 m, covering steel, padstones, making good and structural calculations. The door is priced separately, and Building Control fees are set by your council. All figures are guide prices inc VAT, fixed in a written quote after we survey the wall and see what is above it.
Do I need planning permission for a new opening?
Planning rules for altering an elevation depend on the property and where you are, so it is worth checking with your council before you commit. Flats, listed buildings and properties covered by an Article 4 direction are the most likely to need consent. Wales and Scotland have their own planning rules. Our planning guide sets out the questions to ask.
Do I need building regulations to widen a door opening?
Yes, forming or widening an opening is structural work and needs a Building Regulations application in England, supported by structural calculations. Building Control inspects the work, typically including the steel and its bearings. In Scotland a building warrant is needed. Wales and Northern Ireland follow their own building regulations through local authority or district council building control.
