About our wider doorways & openings service in Holyhead

Wider doorways & openings in Holyhead are planned around the house, not a standard kit. The wider Anglesey area is covered as well. We visit, measure and check what the wall carries, then arrange calculations and building control approval before any steel is ordered.

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.

Worth knowing before you start

  • 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.
  • 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.
  • When an opening widens, the old threshold strip and floor finishes often stop short. Carpet, boards or tiles need joining neatly across the new width, and a change in floor height between rooms may need a threshold bar or a gentle ramp.
  • 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.
  • 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.

Building control and neighbours in Holyhead

In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Isle of Anglesey County Council handles building control for Holyhead. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.

The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Wider doorways & openings near Holyhead

Wider doorways & openings in Holyhead: your questions

Can you work on older or listed homes in Holyhead?

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.

Do you cover Holyhead for wider doorways & openings?

Yes. We carry out wider doorways & openings in Holyhead and the LL65 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

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.

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.
