We deliver expert RSJ installation in Dursley, bringing structural precision and confidence to every project we undertake.
Done right, no shortcuts.
For homeowners wishing to enhance their ground floor, RSJ installation is the ideal choice. By introducing a structural steel beam, you can remove walls that previously divided rooms, ensuring the building's integrity remains intact. We perform every RSJ installation here in Dursley following the precise calculations provided by a structural engineer, ensuring both safety and visual refinement.
If you are connecting a new extension to your property, the structural demands are considerable and require expertise beyond standard building work. RSJ installation in Dursley allows for a clean architectural connection where the steel beam supports the load correctly. We manage the entire process, from temporary propping to building control notifications, completing all associated works.
For landlords developing HMO properties or investors reconfiguring layouts to maximize rental yield, RSJ installation provides a reliable structural option. Installing rolled steel joists at strategic points in your building allows you to make notable alterations without compromising its structural performance. With over 20 years of experience, we deliver each RSJ installation in Dursley with precision for serious property investment.


Our RSJ installation process begins with a detailed review of the structural engineer's calculations to ensure every beam is properly specified and positioned for your project. Temporary propping is systematically managed throughout to protect your property’s integrity. Once the RSJ is securely in place, we handle all necessary building control notifications and complete all making-good works, resulting in a seamless transition between old and new construction that reflects our two decades of experience.
Whether your goal is to open up your ground floor or link an extension to your house, RSJ installation is the structural method that achieves this without compromise. We supply and install steel to the exact specifications given by the engineer, coordinating all trades involved under one point of responsibility. Throughout the process, temporary propping is maintained, ensuring that each stage has the correct approvals. From the first calculations to the final touches, our work is conducted with the confidence that comes from years of structural expertise.
Every RSJ installation we conduct adheres strictly to the structural engineer's calculations, ensuring long-term structural integrity and technical accuracy.
We maintain temporary propping throughout each RSJ installation, safeguarding the existing structure at every phase and providing you with confidence that the work is completed with care.
We handle all notifications to building control as part of your RSJ service, ensuring that you are not left to navigate regulatory requirements alone or risk running into compliance issues.
After the RSJ installation is complete, our team takes care of all finishing works to the highest standard, leaving your space ready for the next phase without needing to coordinate more contractors.
With us managing the RSJ installation alongside any related works, you benefit from a single point of contact, a clear schedule, and over 20 years of structural expertise backing every decision.
Using RSJ installation allows you to open the ground floor or connect an extension to your house, reshaping your property's layout in a structurally sound and architecturally pleasing way.
Water pipes love old masonry. When fitting an RSJ in Dursley, we routinely uncover forgotten copper runs clipped inside hollow cavities. If a central heating line crosses right where steel bearings rest, heating loops drop pressure immediately upon the slightest pinch or vibration. We reroute such plumbing sideways before lifting metal aloft, soldering tidy elbows along joist lines. Then water flows safely elsewhere without soaking fresh padstones.
Cables hide behind plaster. Older cottages often conceal ring mains strung haphazardly through brick mortar, and slicing into a partition can sever power across several rooms if nobody isolates the circuits beforehand. Whenever an RSJ enters an aperture, we isolate matching consumer units, pull live feeds out of harm, and thread them through protective conduit. You avoid scorched wires, dark corridors, and tripped breakers while heavy metal goes straight home into pocket walls.

We start by reviewing the structural engineer's calculations to ascertain the exact RSJ specifications for your project, ensuring every aspect is accounted for before the work begins.
Before altering any load-bearing walls, we ensure temporary propping is installed to support the existing structure safely throughout the RSJ installation.
We manage all required notifications to building control, making sure that the RSJ installation is compliant with existing regulations and well documented from the beginning.
Our team supplies and installs the RSJ to the precise specifications set forth by the structural engineer, whether the work involves opening up your ground floor or merging a new extension with the current property.
Once the RSJ is firmly secured and all propping is removed, we restore all affected areas to a polished, finished state, leaving the space prepared for the next phase of your project.
Crumbling masonry causes trouble. Putting an RSJ in Dursley on soft historic brickwork without cast concrete spreaders cracks adjacent plaster within hours. Heavy girders require firm bases below each flange, because unreinforced stone shifts sideways under intense concentrated weight. We pour deep concrete pads early so bearing points hold solid without crushing delicate sub-walls below.
Bare metal attracts moisture. Bare flanges touching external skins draw autumn chill inward, producing dark condensation patches that ruin fresh paintwork around your new ceiling junction. Whenever an RSJ spans outer boundaries, we wrap the perimeter in dense foil-faced insulation before boarding over. Such detail stops damp spots from appearing above doorway frames when cold winds strike the hillside.


Hallways need space. Long beams cannot bend around narrow porch doorways or squeeze past bulky coat racks. Lifting an RSJ in Dursley demands straight paths through gardens and corridors, so we always ask owners to remove framed pictures, hallway rugs, and low light shades prior to unloading. Tight turns become simple passages once furniture sits elsewhere.
Masonry saws create clouds. Cutting lime mortar releases fine powder that drifts through gaps into kitchen cupboards or behind television sets. Before bringing an RSJ indoors, we seal doorway thresholds using thick polythene sheets secured with low-tack tape. Heavy sheeting keeps grit strictly confined inside the work bay.
Vibrations travel downstairs fast. Drilling lintel beds rattles loose floorboards, and loose items on sideboards can easily tumble onto floor tiles. Prior to hoisting any RSJ into position, moving fragile glassware from nearby display cabinets saves unnecessary heartbreak. Simple precautions preserve your household keepsakes intact while structural masonry gets taken down.

A photo helps identify basic layout, but structural pricing depends on actual wall thickness and floor loading above. Without engineer calculations or seeing bearing points in person, steel sizing remains uncertain because hidden timber directions dictate girder depth.
Clearing large furniture away from work zones makes room for tall screw props. Dust travels through every keyhole, so boxing up small ornaments and clearing access corridors protects possessions while heavy metal gets carried indoors across Dursley.
Interior steelwork proceeds through rain, but freezing temperatures delay casting the wet concrete padstones that support girder ends. If mortar freezes before curing properly, steel cannot take weight until warmer conditions allow materials to set solid.
Structural contracts focus on installing steel and making bearings secure. Making good wall plaster, repainting ceilings, and boxing in exposed metal with fire-rated plasterboard usually sit as separate decorative trade packages unless specifically written into the initial agreement.
