About our wider doorways & openings service in Chatham
We cover wider doorways & openings in Chatham (ME1, ME2, ME4) and the streets around it. The wider Kent area is covered as well. Each job is designed by a structural engineer and approved through Medway Council before work begins.
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
- 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.
- 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.
- 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.
- 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.
- 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.
How the job runs in Chatham
Free visit
A short visit to Chatham 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 Medway Council, 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 Chatham
Structural openings in English homes need building regulations approval before work starts. Medway Council 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 Chatham: your questions
Do you also work near Chatham?
Yes. We also cover nearby towns including Rochester, Gillingham, Strood and Maidstone.
Do I need a party wall agreement for wider doorways & openings in Chatham?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
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 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.
What happens at the survey visit in Chatham?
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.
