Structural Work & RSJ Installation Hertfordshire — Ensuring Safety and Stability
When planning a home extension, loft conversion, or major refurbishment, structural integrity is paramount. Removing walls, adding new openings, or creating two-storey extensions requires careful design, proper materials, and expert installation to ensure your home remains safe and stable.
At AKB Construction, we specialise in structural work and RSJ installation across Hertfordshire, including Rickmansworth, Croxley Green, Watford, Hemel Hempstead, St Albans, and surrounding towns. Our owner-led, hands-on approach guarantees precise installation, compliance with building regulations, and complete client support from survey to handover.
Why Structural Work Matters
Structural work isn’t just about installing steel beams — it’s about maintaining the safety, longevity, and value of your property. Incorrectly handled structural work can lead to:
- Cracking in walls and ceilings
- Sagging floors or beams
- Water ingress through compromised structures
- Potential failure of load-bearing elements
- Increased risk during renovations
By engaging experienced builders who understand Hertfordshire’s housing stock, you ensure structural alterations are performed safely, efficiently, and in accordance with regulations.
What is an RSJ?
RSJ stands for Rolled Steel Joist, a type of structural steel beam used to support loads when removing walls or creating openings.
Common applications include:
- Knock-throughs for open-plan living
- Rear or side extensions
- Loft conversions and dormers
- Two-storey additions
- Supporting masonry above new doorways or windows
RSJs are designed and installed to carry the weight safely, transferring loads to foundations or supporting walls.
Types of Structural Work We Handle
Load-Bearing Wall Removal
Removing a load-bearing wall requires careful calculation and temporary support. Our process includes:
- Survey and assessment of wall type
- Structural engineer consultation
- Temporary props or acrows to support the building
- RSJ or steel beam installation
- Finishing and plastering to restore aesthetics
Steel Beam & RSJ Installation
RSJs and steel beams are essential for openings in walls, extensions, and loft conversions. We ensure:
- Correct sizing of beams according to load
- Accurate installation with proper bearing points
- Compliance with building regulations
- Concealed finishes where required
Extensions & Loft Conversions
Extensions and loft conversions often require structural reinforcement. We provide:
- Structural calculations and drawings
- Coordination with engineers
- Installation of RSJs and steel supports
- Integration with existing walls and floors
Chimney & Masonry Support
Older Hertfordshire homes often have chimneys or masonry features that need supporting during renovations. We manage:
- Removal or partial demolition safely
- Installation of supporting steels or RSJs
- Rebuilding or finishing to match original aesthetics
The Structural Work Process
- Initial Consultation & Survey
We assess your property, intended work, and any structural constraints. - Structural Assessment
We evaluate foundations, walls, and load paths to determine required support. - Engineer Calculations
Where necessary, a structural engineer specifies RSJ size, bearing points, and load distribution. - Quote & Schedule
Transparent written quotation with timelines and scope. - Preparation
Temporary supports, site protection, and clear access points are set up. - Installation
Steel beams, RSJs, and supports installed by qualified trades. - Inspection & Certification
Works checked against engineer specifications, with Building Control inspection where required. - Finishing
Plastering, making good, and integrating new structural elements into the property.
Local Considerations for Hertfordshire Homes
Older Housing Stock
Many Hertfordshire properties (1930s–1970s semi-detached and detached houses) have walls and structures that require careful evaluation before any alteration.
Soil & Foundations
Clay and chalk soils prevalent in the region affect foundation load distribution. RSJ and beam installation considers these factors to ensure stability.
Planning & Party Wall
If a wall is shared with a neighbour, a Party Wall Agreement may be required. We handle notifications and ensure all work is compliant.
Access & Logistics
Some streets in Rickmansworth, Croxley Green, and Watford are narrow, requiring careful planning for crane access, deliveries, and skip placement.

Frequently Asked Questions
Do I need an engineer for an RSJ?
Yes. All load-bearing walls and significant structural changes require calculations by a qualified structural engineer.
How long does RSJ installation take?
Small knock-throughs can be completed in a day or two. Larger extensions or loft conversions require a full build schedule.
Can I live in the house during structural work?
Yes, in most cases. Temporary supports and safe zoning allow you to remain in parts of your home.
Do I need planning permission?
Internal structural changes rarely require planning, but extensions or loft conversions may. We advise and coordinate approvals.
