Wider doorways & openings in Epsom: how it works
If you live in Epsom, wider doorways & openings can usually be planned and priced after a single survey visit. Epsom is around 12.5 miles from Woking, and we cover both. We cover KT17, KT18, KT19, KT21 and SM7, and we fix the price in writing once the layout and scope are agreed.
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.
Things to plan for
- Forming or widening an opening in a load-bearing wall is building work needing building regulations approval in England and Wales. In Scotland a building warrant is required before work starts, and in Northern Ireland an application is made to the council's building control.
- 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.
- 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.
- Widening doorways is a frequent adaptation for wheelchair users and people using walking frames. Where a council grant or adaptation scheme is helping to pay, check its requirements for clear opening width before the opening is designed.
- 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.
What happens, step by step
Survey in Epsom
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.

Building control and neighbours in Epsom
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 Epsom
Do you also work near Epsom?
Yes. We also cover nearby towns including Ewell, Banstead, Sutton and Leatherhead.
Can you work on older or listed homes in Epsom?
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.
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.
How wide can I make a doorway?
That depends on the wall, what it carries and how much solid wall is left at each side for the support to bear on, and a structural engineer sets the limit. Many people go from a single door to a double-width opening, and beyond that the job starts to become a partial wall removal.
What if there is a radiator or switch where the new opening goes?
It gets moved before the opening is cut. Radiators and pipework are relocated by a heating engineer, and switches and sockets by an electrician, with notifiable electrical work in England meeting Part P. These items are priced separately in the quote, so you can see what each one adds.
