About our wider doorways & openings service in High Wycombe

Need wider doorways & openings in High Wycombe? Our coverage runs across Buckinghamshire, so nearby villages are included too. We survey the property, arrange the engineer's design, deal with local building control, fit the steel and make good, all under one quote for HP10, HP11, HP12, HP13 and HP15 addresses.

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

  • 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.
  • 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.
  • Standard internal doors come in set widths, so it makes sense to size the opening to suit an off-the-shelf door and lining. Odd sizes need made-to-measure doors and linings, which take longer to arrange.
  • 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.
  • 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.

What happens, step by step

  1. Look and measure

    We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.

  2. Design and price

    Calculations come back from the engineer and we confirm your fixed written price, line by line.

  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. Fit, inspect, finish

    The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for High Wycombe

For High Wycombe, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

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.

Questions about wider doorways & openings in High Wycombe

Do you also work near High Wycombe?

Yes. We also cover nearby towns including Amersham, Maidenhead, Chesham and Chalfont St Peter.

Can you work on older or listed homes in High Wycombe?

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 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.

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.

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.
