Planning RSJ installation in Washington
Our RSJ installation service in Washington covers everything from the first visit to the completion paperwork. We also work in nearby Sunderland, roughly 5.4 miles away. Postcode districts we cover here include NE37 and NE38.
We supply and fit the steel from start to finish. That includes arranging the calculations, having the beam fabricated with the right end plates, holes and primer, getting it into the property, setting it on its bearings, and packing it so it takes the load. Building control, propping and making good sit in the same itemised quote.
What to expect
- RSJ originally meant a rolled steel joist with tapered flanges. Most beams supplied for homes today are universal beams with parallel flanges, but the term RSJ has stuck, and builders, engineers and building control all understand what it means.
- The engineer chooses the section type for the job. Universal beams suit most spans, universal columns are stockier and used as posts or where depth is limited, parallel flange channels fit against walls or timbers, and box sections suit slim or exposed members.
- Sometimes two beams are bolted side by side with spacers, either to carry a thick wall or to fit through a tight space. Bolt spacing and spacer type come from the engineer's design rather than being decided on site.
- Padstones spread the concentrated load from each beam end into the masonry below. They may be concrete, engineering brick or a steel plate, depending on the engineer's design and the strength of the wall beneath.
- Where a long beam cannot be carried into a property in one piece, the engineer can design a bolted splice so it arrives in two or more lengths. The splice position and bolts are part of the calculations and must be installed exactly as drawn.
How the job runs in Washington
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.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit a building notice or full plans application to Sunderland City Council, so approval is in place before the wall is touched.
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 Washington
In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Sunderland City Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.
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.

RSJ installation in Washington: your questions
How soon can RSJ installation start in Washington?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
Do you cover Washington for RSJ installation?
Yes. We carry out RSJ installation in Washington and the NE37 and NE38 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
What is included in an RSJ supply and fit price?
Our itemised written quote sets out the calculations, building control, steel and fabrication, delivery, lifting, padstones, propping, labour, fire protection and making good as separate lines. Once the specification and scope are agreed, the price is fixed in writing, so you know the full cost before work starts.
How heavy is an RSJ and how is it lifted?
Weight varies widely with the section and length, from beams a small team can carry to steels needing mechanical lifting. The lift is planned at the survey, using enough people, trolleys and suitable lifting equipment so the beam goes up safely and level onto both bearings.
Do I need building regulations approval to fit an RSJ?
Yes, when the RSJ carries structural load such as a wall, floor or roof. In England and Wales building control is notified or approved beforehand, Northern Ireland needs a council application before work starts, and Scotland requires a building warrant first. A completion certificate confirms sign-off at the end.
