Is a sliding door for a new opening a good fit for your home in Crawley?
Most homeowners choosing sliding doors for new openings want the same things: more light, a clear view and a door that is easy to live with.
Where a Crawley 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 Crawley 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.
- Making good the reveals and head after the steel goes in leaves a square, plumb opening, which is what a precision-made sliding door needs to run smoothly.
- 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.
- 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.
How much sun will a door in Crawley get?
Because Crawley 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.

Survey, manufacture and fitting around Crawley
Surveys in the RH10 district are booked at a time that suits you. Once the opening is ready and measured, manufacture is typically 4–6 weeks for the door after the opening is measured; building work scheduled around approvals; on fitting day the frame is set level and sealed, and the panels are adjusted so they glide properly. Fitting usually takes 3–5 days of building work, then 1–2 days to fit the door.
Do you need approval in Crawley?
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.
Finishes and extras for sliding doors for new openings
- Window to door conversion. Cutting down below an existing window to form a door opening to the garden.
- Steel beam with padstones. A beam sized by the engineer to carry the wall, floors and roof above.
- Concealed steel. Setting the beam so it sits above the ceiling line, giving a cleaner head detail inside.
Questions about sliding doors for new openings in Crawley
Do I need building approval for sliding doors for new openings in Crawley?
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.
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.
Does the Party Wall Act apply to my new opening?
The Party Wall etc. Act 1996 (England and Wales) may apply if the new steel beam bears on, or is cut into, a wall you share with a neighbour, as is common in semi-detached and terraced houses. If it applies, you must serve notice on the neighbour before the work starts. A rear wall entirely on your own property is less likely to be affected.
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.
