Wider doorways & openings in Bexley: how it works
If you live in Bexley, wider doorways & openings can usually be planned and priced after a single survey visit. The wider London area is covered as well. We cover DA5, DA6, DA7, DA8 and DA14, 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.
What to expect
- 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.
- Light switches, sockets and cables often sit right beside a doorway. These are moved before cutting, and any electrical alterations in England must comply with Part P of the building regulations where they are notifiable.
- 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.
- 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.
- 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.
From survey to sign-off in Bexley
Free visit
A short visit to Bexley to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
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.
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.

Approvals in Bexley
For Bexley, 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.
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 Bexley
Do you cover Bexley for wider doorways & openings?
Yes. We carry out wider doorways & openings in Bexley and the DA5, DA6, DA7, DA8 and DA14 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 much do wider doorways & openings cost in Bexley?
As a guide, budget £1,300–£3,200 including VAT for widening an internal doorway in Bexley, based on published UK cost guides adjusted for London prices (+28%). 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.
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.
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.
What happens at the survey visit in Bexley?
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.
