Structural work is where cutting corners has real consequences.
A steel beam specified to carry a load needs to be the right steel, installed on correct bearing, with padstones the right size and the temporary propping done safely. “Near enough” isn’t a category in structural engineering. We work with qualified structural engineers on every project requiring steelwork. Their drawings specify what goes in, and our team installs it correctly.
We’ve put in hundreds of steel beams across Derbyshire, from simple RSJ lintels to multi-span portal frames on large extension projects. We’ve also taken on structural repairs where a previous builder installed the wrong specification or got the installation wrong. Those jobs cost far more to fix than they would have to do correctly first time.
Every structural job we carry out has Building Control notification and sign-off as standard. You’ll receive the completion certificate, which matters both for insurance purposes and for future buyers when the property is sold.
Structural work types
What Kind of Structural Work Do You Need?
We carry out a range of structural alterations in residential properties, all with structural engineer drawings and Building Control sign-off.
RSJ / Steel Beam Installation
Open up your ground floor by removing a load-bearing wall and installing a steel beam. The most common structural job in residential properties. Correctly specified, correctly installed, properly signed off.
Chimney Breast Removal
Remove a redundant chimney breast to reclaim floor space, often on multiple floors simultaneously. Requires careful propping and correct padstone bearing for the flue stack above. We handle all trades involved.
Load-Bearing Wall Removal
Full structural wall removal to create open-plan living. Includes structural engineer assessment, correct temporary propping, steel installation and full making good of all finishes.
Portal Frame & Complex Steelwork
Multi-span structural frames for large extensions, double-storey openings and complex alteration projects, designed by structural engineers and installed by our team on projects of all sizes.
Full scope, no gaps
From structural engineer drawings to the last skim of plaster.
Structural work isn’t just the steel. It’s everything involved in doing it correctly and finishing it properly. Here’s the full scope we handle in-house.
- Structural engineer drawings (we’ll recommend engineers)
- Building Control notification & inspection
- Temporary propping & support
- Wall or chimney breast removal
- Steel beam supply & installation
- Padstone installation
- Brickwork & blockwork making good
- Plasterwork reinstatement
- Flooring reinstatement (where affected)
- Joinery reinstatement (skirting, coving)
- Decoration of affected areas
- Building Control sign-off & completion certificate
We carry out every element of a structural job in-house, so you won’t be left with a steel beam and bare plasterboard waiting for three separate trades to come back and finish. One team, one invoice, finished and signed off.
Our process
How Your Structural Project Comes Together
Structural work has a clear and non-negotiable sequence. Here’s how we approach every steel and alteration project.
01
Site Assessment
Gaz visits and establishes exactly what’s load-bearing, what’s involved in the alteration, and what structural engineer input is required. You get an honest view of the scope and cost upfront.
02
Structural Engineer Commissioned
We work with qualified local structural engineers who will specify exactly what steel is required, the bearing dimensions, and any associated works. We can recommend engineers we’ve worked with on many previous projects.
03
Building Control Notified
The Building Control application is submitted and approved before any propping or structural work begins. The correct approvals are always in place, and there are no shortcuts here.
04
Works Carried Out & Signed Off
Our team carries out the structural works correctly, to the engineer’s specification, with the Building Control inspector signing off at the appropriate stages. You receive the completion certificate at the end.

Where we work
Structural Work Across Chesterfield & Derbyshire
We’re based in Chesterfield and carry out structural alterations across the town and surrounding areas. Most structural jobs are part of a larger project, like an extension, renovation or loft conversion, and we handle the whole thing.
Chesterfield: Victorian Terraces & Post-War Estates
Victorian terraces throughout Brampton, Walton and Newbold are full of redundant chimney breasts and load-bearing internal walls, both frequent targets for structural alteration. Post-war semis on Loundsley Green and Hasland regularly have walls removed to create open-plan ground floors. We know these property types well.
Dronfield, Eckington & North Derbyshire
Extension projects across this area regularly require structural steel to open the kitchen or living area into the new build. We carry out the structural element as part of the extension project, so there’s no need to coordinate a separate steelwork contractor.
Sheffield & South Yorkshire
We carry out structural work regularly across Sheffield and South Yorkshire, particularly as part of larger renovation and extension projects. Totley, Dore and the western suburbs have a high proportion of detached properties requiring structural alterations as families reconfigure ground floors.
Wider Derbyshire
Structural work forms part of many of our renovation and extension projects across the wider Derbyshire area. If you have a structural alteration project, standalone or as part of a larger build, get in touch and we’ll assess it properly.

FAQ
Structural Work Questions Answered
The most common questions homeowners ask us before starting a structural alteration project in Chesterfield and Derbyshire.
Yes, for any load-bearing wall removal or structural opening, you will need structural engineer drawings specifying the correct steel section, the bearing dimensions and the padstone requirement. Building Control will not sign off structural work without this documentation. We work with local structural engineers on every project requiring steelwork and can recommend professionals we’ve used on many previous jobs.
A straightforward single steel installation, opening up a ground-floor wall for example, typically takes 2–3 days including propping, cutting, steel installation, padstone installation and initial making good. The main disruption is dust and the period while the temporary propping is in place. We keep the working area contained and clean up thoroughly throughout. For a standalone steel installation, most clients can remain in the house throughout.
Technically possible, but not advisable. Chimney breast removal on a ground floor requires a steel to support the breast above, which in a two-storey property means the breast on the first floor and the chimney stack above that. Getting the temporary propping wrong, or installing insufficient bearing for the steel, can cause serious structural failure. It’s also notifiable under Building Regulations. A completion certificate is required and matters for insurance and future sale. Get it done properly.
A knock-through involves removing a load-bearing wall between two rooms, typically the kitchen and dining room on a ground floor. The sequence is: structural engineer specification; Building Control notification; temporary propping of the load above; removal of the wall; installation of the steel beam on padstones; making good of the ceiling, walls and floor; plastering; decoration. We handle every stage in-house.
A straightforward single steel beam installation takes 2–3 days on site. A more complex project, chimney breast removal on multiple floors or a multi-span portal frame for an extension, can take 1–2 weeks. Allow additional time upfront for structural engineer drawings and Building Control notification. We’ll give you a full programme before we start.
Often goes hand in hand
Other Services We Handle on Structural Projects
Structural work is rarely a standalone job. It’s usually the foundation stage of something bigger. We carry all these trades in-house.
House Extensions
Most single and two-storey extensions require structural steelwork to open the existing house into the new build. We carry out both as one continuous project.
View service →Loft Conversions
Dormer and hip-to-gable conversions require structural steel for the ridge beam and trimmer joists. We install these as part of the loft conversion project.
View service →Full Renovations
Full property renovations often include structural alterations: knock-throughs, chimney breast removals and opening up between floors. All handled as part of the renovation scope.
View service →Period Restoration
Period properties often need structural repairs such as tie bar installation, chimney stack rebuilding and lintel replacement, alongside the decorative restoration work.
