About our wider doorways & openings service in Wiltshire

Wider doorways and openings are gaps formed or enlarged in internal walls, with a lintel or steel beam carrying the masonry and loads above. They sit between a simple door change and a full wall removal: the span is shorter, but each opening still needs the right support and approval if the wall is structural.

Looking for wider doorways & openings in Wiltshire? Towns we cover include Trowbridge, Swindon and Salisbury, among other places in the area. Our teams handle the calculations, the building control approval, the propping and the steel itself, and leave the opening ready for plastering and decoration.

Worth knowing before you start

  • Openings are cut with a masonry saw where possible rather than broken out with a hammer. Clean cuts keep the brickwork either side sound, give a straighter edge for plastering and send less vibration through the rest of the wall.
  • Older door surrounds and walls can hide asbestos in textured coatings, insulating board above doors or panelling. In buildings built before 2000 it must be identified before the wall is cut, so a refurbishment survey of the area is arranged where there is a risk.
  • 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.
  • The main cost factors are whether the wall is structural, the width of the opening, what the support bears onto, how much electrical or heating work has to move, and whether you want new door linings and doors fitted as part of the job.
  • In older houses, a doorway may already have a timber lintel that has rotted or a brick arch that is hard to extend. These are replaced rather than added to, and the engineer allows for soft lime mortar and any cracking found once the wall is opened.

From survey to sign-off in Wiltshire

  1. Free visit

    A short visit to Wiltshire to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. 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.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

How much should I budget in Wiltshire?

As a guide, budget £1,050–£2,600 including VAT for widening an internal doorway in Wiltshire, based on published UK cost guides adjusted for prices in the South West (+3%).

JobTypical guide rangeWhat it usually covers
Widening an internal doorway£1,050–£2,600Opening widened with a new lintel or short beam, approval where structural, and making good

Lintel replacement£410–£1,240 per lintelPropping, removing the old lintel, new lintel set on beds and brickwork made good

Figures include our approximate regional adjustment for prices in the South West (+3%) and are rounded. How these figures are worked out.

Building control and neighbours in Wiltshire

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.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Wider doorways & openings in Wiltshire: your questions

Do you cover Wiltshire for wider doorways & openings?

Yes. We carry out wider doorways & openings in Wiltshire. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

How much do wider doorways & openings cost in Wiltshire?

As a guide, budget £1,050–£2,600 including VAT for widening an internal doorway in Wiltshire, based on published UK cost guides adjusted for prices in the South West (+3%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

Will widening a doorway make a mess?

There is some dust and noise, mainly on the day the opening is cut. We screen the area, protect floors along the route and use dust extraction on saws where possible. Rooms either side are affected for a day or two, while the rest of the house stays in normal use.

Can I move a doorway to a different position?

Usually, yes. The old doorway is blocked up and a new opening is formed with the support the engineer specifies, and both changes are dealt with together for building control if the wall is structural. Moving a door can release wall space for furniture or a better kitchen or bedroom layout.

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.

Can I widen a doorway in a load-bearing wall?

Yes. The extra width is spanned by a lintel or steel beam that a structural engineer specifies, sitting on solid bearings either side. Because the wall is structural, the work needs building control approval in England and Wales, a building warrant in Scotland, or a council building control application in Northern Ireland. We arrange the design and approval.

Can you work on older or listed homes in Wiltshire?

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.
