Smarter Steel Preparation for Safer, Greener Projects 

When it comes to structural refurbishment, the condition of existing steelwork can’t be ignored. Rust, old coatings, and surface contaminants don’t just affect performance, they affect safety and compliance. 

But traditional methods like shot blasting or chemical stripping bring their own problems: noise, dust, heavy waste output, and significant disruption. That’s why Sentinel has added a new solution to our specialist service portfolio: Laser Cleaning. 

This is surface preparation, redefined. Cleaner, safer, and dramatically more precise, Laser Cleaning is ideal for high-spec refurbishments and sensitive live environments where control is everything. 

What Is Laser Cleaning, and Why Is It Better?

Laser Cleaning uses high-powered light to vaporise rust, scale, and contaminants from metal surfaces. Unlike abrasive blasting, it doesn’t rely on grit or chemicals to strip surfaces. Instead, it delivers pinpoint precision, cleaning steel without damaging it. 

That makes it an ideal method for: 

• Existing steel structures being refurbished or redeveloped 

• Areas where coatings or corrosion need to be removed with minimal disruption 

• Sites where environmental controls, live operations, or heritage sensitivities are in play 

This isn’t just an upgrade; it’s a smarter alternative altogether. 

The Results Speak for Themselves 

On a recent project, Laser Cleaning helped: 

• Avoid over 211 tonnes of waste 

• Save more than 257,000 kg CO₂e 

• Cut landfill waste by 99% compared to shot blasting 

• Achieve a lower overall project cost thanks to faster delivery and reduced labour requirements 

By removing abrasive materials from the process, Sentinel is helping their clients lower emissions, reduce site waste, and streamline post-clean-up operations, all while protecting critical building fabric and keeping sites running safely.

Where Laser Cleaning Works Best

This isn’t a one-size-fits-all tool. Laser Cleaning is already proving valuable in: 

• Occupied or live buildings where dust and noise must be controlled 

• Heritage refurbishments, where sensitive detailing can’t be compromised 

• Complex access areas, where scaffolding or protective shielding might restrict traditional blasting 

• Commercial, industrial, or healthcare environments, where air quality and hygiene are priorities 

It’s particularly suited to: 

• Exposed steel beams, columns, brackets and structural fixings 

• Areas where abrasive blasting would pose a contamination or disruption risk 

• Refurbishment projects where surface prep is needed but waste and downtime are limited 

Part of a Cleaner Future

Laser Cleaning is more than an innovation, it’s a step toward greener, more responsible construction. By reducing waste, lowering emissions, and avoiding the damage and disruption of abrasive methods, we’re helping clients hit sustainability targets without compromising on performance. 

And as regulatory and environmental standards tighten, that kind of smart thinking matters more than ever.
