Who It's For

For Whom Is RSJ Installation Designed

Homeowners Seeking Space

RSJ installation is ideal for homeowners wishing to open up their ground floor and create a more generous living environment. By introducing a structural steel beam, we can remove walls that previously divided rooms, all while maintaining the building's integrity. Our installations comply with the detailed calculations provided by a structural engineer to ensure safety and aesthetic appeal.

Clients Planning Extensions

When joining a new extension to an existing building, structural demands require far more than simple building work. RSJ installation enables the integration of the two structures in a manner that is both architecturally pleasing and structurally sound. We manage the entire process, from temporary propping to notifying building control, ensuring a smooth experience from start to finish.

Landlords and Property Investors

For landlords enhancing HMO properties or investors looking to reconfigure layouts for increased rental yield, RSJ installation provides a reliable, long-lasting building solution. By implementing rolled steel joists at crucial points in the structure, we can facilitate impactful spatial changes without compromising structural integrity. With over 20 years of experience overseeing complex projects, we execute every RSJ installation with the precision and accountability necessary for serious property investment.

Structural Steel Installation

Our RSJ installation in Mangotsfield begins with a careful review of the structural engineer's calculations, ensuring every beam is specified, positioned, and loaded precisely as needed. We manage temporary propping throughout the entire process to uphold your property's integrity. Once the RSJ is securely in place, we handle building control notification and finish all areas to a standard that mirrors the quality of the underpinning structure. The result is a seamless transition between old and new, carried out with the precision that two decades of experience demands.

Opening Up Your Space

The goal may be to open up the ground floor or connect a new extension to your existing house, and our RSJ installation is the key without compromises. We supply and install structural steel according to the engineer's specific directions, merging efforts from all trades under one management. Temporary propping is sustained throughout the project, and every phase of work is compliant with all relevant approvals and notifications. From initial calculations to the final touches, we conduct operations with the calm confidence of a contractor experienced in achieving structural precision.

Preparing Your Home Before Structural Works

Clearing the Route Indoors

Dust travels everywhere during knock-throughs. Heavy steel beams must move through front doors, narrow hallways, or side gates, meaning all framed pictures, hallway rugs, and coat stands should be boxed away entirely. When managing an RSJ in Mangotsfield, we always ask clients to isolate adjacent lounges by sealing doorways with polythene sheeting, because masonry grit easily penetrates internal hinges and deep carpet piles. Moving furniture to distant rooms protects fabric upholstery from airborne lime mortar. Clear routes prevent chipped skirting boards.

Handling Live Utilities

Old masonry walls conceal surprises. Water pipes, lighting loops, and central heating feeds often run vertically through partitions that are marked for demolition, demanding temporary isolation before hammers touch brick. We trace live cables across joists so an electrician can safely decommission the circuit rather than leaving bare copper exposed under overhead timber joists. For homes connected around nearby Kingswood or Keynsham, locating the stopcock early avoids emergencies if an unmapped lead pipe sits embedded inside older lime bedding. Disconnected radiators should be drained down to buckets well beforehand.

Step-by-Step RSJ Installation Process

  1. Structural Assessment

    We start by evaluating the structural engineer's calculations to identify the specific RSJ requirements for your project, ensuring every detail is addressed before work begins.

  2. Installation of Temporary Propping

    Before interacting with any load-bearing wall, we install temporary propping to securely support the existing structure during the RSJ installation process.

  3. Building Control Notification

    We take care of all necessary notifications to building control for you, making sure that the RSJ installation complies with current regulations and is properly documented from the outset.

  4. Supplying and Installing Steel

    Our skilled team delivers and installs the RSJ according to the precise specifications provided by the structural engineer, be it for opening the ground floor or integrating a new extension.

  5. Final Touches and Making Good

    After the RSJ is securely installed and all propping is removed, we restore all surrounding areas to a clean, finished state, ensuring the space is ready for the next stage of your project.

Routine Upkeep and Post-Installation Care

Checking Hairline Plaster Shrinkage

Timber joists dry out slowly. Over several months, seasonal changes cause natural movement around padstones, which can lead to faint micro-cracks along the fresh skim coat. Such shifts are cosmetic rather than load-bearing faults. When assessing an RSJ around Mangotsfield, we advise homeowners to let the new plaster dry out during summer before applying heavy decorative wall coverings over the boxed framework. A flexible filler bridges gaps.

Preventing Concealed Moisture Build-Up

Cold metal invites condensation. Bare steel hidden inside ceiling voids or unheated boundary corners requires proper fire-rated encasement and thermal wrapping to prevent warm indoor air from condensing against cold flanges. Moisture running down untreated iron eventually creates damp staining on ceiling plasterboard or rots adjacent ceiling joists. Inspecting your roof drainage helps, because a minor gutter leak above an outer wall pier can soak the supporting padstone below.

Coordinating Structural Steelwork With Other Building Trades

Routing Overhead Plumbing Pipes

Steel cannot be drilled arbitrarily. Plumbers cannot bore large holes through load-bearing flanges to run waste stacks or central heating pipes across a room. Installing an RSJ across Mangotsfield requires planning subfloor levels in advance, ensuring waste runs drop either side of the beam or pass cleanly beneath custom joist hangers. Timber trimmers often carry the load instead.

Aligning Joinery and Framework

Floor levels rarely match perfectly. When taking out a central wall, floorboards on one side might sit slightly higher than aged tongue-and-groove boards on the opposite side. Carpenters need sufficient depth beneath the steel beam to pack, level, and anchor new subfloors flush without creating uneven thresholds or trip hazards. Flush plasterboard finishes require accurately measured timber grounds.

Integrating Electrical Wiring Safely

Cables need adequate physical separation. Electricians should never string twin-and-earth cables directly over sharp metal edges, as thermal vibration causes plastic sheathing to wear down over time. Metal beams must be properly earthed by certified trades, with cables routed through protective grommets, dedicated battens, or dropped ceilings. Keeping cables away from hot central heating pipes preserves insulation integrity.
