Structural Alterations Kent
in the South East

RJ Construction specialises in structural alterations projects from simple lintel replacements, chimney breast removal or repairs, fitting RSJ so that a wall can be knocked through, steel column erections and much more.

You may be a bit unclear on what an RSJ actually is – many people refer to them as a Supporting Joist or a Reinforced Steel Joist, but these are misnomers. An RSJ is as an acronym for Rolled Steel Joist. The same shape of steel beam can also be called an I-beam or H-beam, or simply a Universal Beam.

In practice, these beams are made in a strong H-shape, and are installed so that the long flat sides of the H are at the top and bottom of the beam, providing a very strong surface on which upper storeys, wall sections or ceilings and roofs can be constructed.

If the wall you are wanting to remove is load bearing, you will need a structural drawing from an engineer. This can be included within our package or to speed the process up you can organise this beforehand. We highly recommend Mark at Torcal who completed all of our drawings.

Do you charge for estimates?

Our estimates are free and no obligation but for a structural report there is a fee.

Are you insured to carry out work on my premises?

Yes, we have full liability insurance up to 2 million pound to cover us for all works undertaken.

Can I see examples of your work locally?

Yes, once we have done the initial estimate you can view previous work if required.

Do I need planning permission?

You should not need to apply for planning permission for internal alterations including building or removing an internal wall.

If you live in a listed building, however, you will need listed building consent for any significant works whether internal or external.

How long should it take to install a new lintel / RSJ

An average lintel replacement takes two days – three days with plastering and making good. An average RSJ installation takes one week with plastering and making good.

How do I pay for my project?

For projects of under £2000 we accept payment on completion. For projects of £2000 or above a £10% commitment to works deposit will be required and a stage payment plan detailing when the payments will be required.
