Planning wider doorways & openings in Banstead
Our wider doorways & openings service in Banstead covers everything from the first visit to the completion paperwork. Banstead is around 14.5 miles from Crawley, and we cover both. Postcode districts we cover here include KT17, KT18, KT20 and SM7.
We arrange a survey visit, structural calculations where the wall is load-bearing, building control, propping, the lintel or beam, new door linings if you want them, and making good. One itemised written quote covers the lot, and the price is fixed in writing once the opening size and finish are agreed.
Key points for your project
- For a modest increase in width, a lintel may be all that is needed, while a wider opening carrying a floor or wall usually needs steel. The engineer chooses the type and size from the actual loads, never from the opening width alone.
- In hallways, a new or wider opening into the living room can affect the protected route from the stairs to the front door. Building control may require fire doors, smoke alarms or other measures, especially in houses with three or more storeys.
- Each side of the new opening needs enough solid wall for the lintel or beam to sit on. If the opening runs close to a corner, another doorway or a chimney breast, there may not be enough masonry, and a column or padstone may be required.
- Light switches, sockets and cables often sit right beside a doorway. These are moved before cutting, and any electrical alterations in England must comply with Part P of the building regulations where they are notifiable.
- Widening a single doorway in a load-bearing wall usually takes one to two days for the structural work. The plaster then needs time to dry before the door linings are decorated or a new door is hung.
What happens, step by step
Survey in Banstead
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Banstead
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Questions about wider doorways & openings in Banstead
Do you cover Banstead for wider doorways & openings?
Yes. We carry out wider doorways & openings in Banstead and the KT17, KT18, KT20 and SM7 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can you work on older or listed homes in Banstead?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
How long does it take to widen a doorway?
The structural part usually takes one to two working days: propping, cutting the opening, fitting the lintel or beam and packing it. Plastering follows, then a few days of drying before linings are painted or a new door is hung. Building control inspection fits in once the support is in place.
Do I need building regulations to widen an internal door?
Only if the wall is load-bearing or the change affects fire safety, such as the escape route from upstairs. Widening an opening in a non-structural stud partition usually does not need structural approval. We confirm which applies at the survey, and handle the building control application or notice where it is needed.
Is a lintel or a steel beam needed for a wider door?
It depends on the loads. A lintel can be enough for a modest widening under light loads, while an opening carrying floor joists or a wall above usually needs steel. The engineer decides from the actual loads and span rather than the width alone, and we fit whichever is specified.
