What our mobile welders do on site
We attend the property, assess the problem and carry out the repair work on site wherever the structure allows.
- MIG, MMA and TIG welding in mild steel, stainless steel and aluminium
- Cutting, coring, drilling and grinding to suit existing structures
- Steel beams cut in and welded on live refurbishments
- Plant platforms, walkways, ladders and access steelwork
- Gates, railings, frames and bespoke brackets made on site
- Alterations to existing steelwork where nothing fits the drawing
A fleet of mobile workshops, not a man with a van.
Pronto Welding Ltd runs 25 fully equipped mobile workshop vans with experienced installation and welding teams — which is why we can survey, fabricate and fit in the same visit.
25 fully equipped mobile workshops
Not one person with a welder in a car boot. Each van is a workshop set up for welding, cutting, drilling, alterations and installation.
Teams already working in London
We run crews across London and the South of England every day, so we can often respond at relatively short notice.
40 employed welders and installers
Directly employed, insured and CHAS accredited — no agency labour and no subcontracted welders turning up in our place.
Vans built as workshops, not toolboxes
Each van carries welding plant, generators, cutting and drilling equipment, consumables and steel stock, so measuring, fabricating and fitting all happen in the same visit.
Access, permits and site rules
London sites mean restricted access, congestion and hot works permits. Our supervisors handle induction, permits and delivery windows so work starts on time.
Directly employed operatives
40 employed welders and installers, not agency labour. The same people come back for the next phase, which is why most of our London work is repeat business.
Contractors, managers and owners
We work as a steelwork subcontractor to main contractors, and directly for property managers, facilities teams and building owners who need one welder who can do the whole job.
From survey to completed on-site weld
