About our wider doorways & openings service in Corby

Our wider doorways & openings service in Corby covers everything from the first visit to the completion paperwork. We also cover the surrounding towns and villages in Northamptonshire. Postcode districts we cover here include NN17 and NN18.

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.

What to expect

  • 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.
  • 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.
  • Hallway walls are often load-bearing because they line up with walls upstairs and carry the floor joists or the stairs. A wall that sounds hollow when knocked is usually a stud partition, but older homes can have timber walls that still carry loads, so the engineer checks.
  • 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.
  • 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.

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.

Approvals in Corby

For Corby, 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 Corby

How much do wider doorways & openings cost in Corby?

As a guide, budget £980–£2,450 including VAT for widening an internal doorway in Corby, based on published UK cost guides adjusted for prices in the East Midlands (-2%). 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.

What happens at the survey visit in Corby?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

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 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.

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 Corby?

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.
