Laser cleaning is not a safe choice for stripping paint inside homes or from wooden surfaces in a domestic setting. Alberny Restorations has stopped all trials for indoor, wood and domestic use, and will only offer widebeam laser cleaning in the South West for industrial work carried out inside its own secure facility.

Laser cleaning is often promoted as a clean, modern way to strip paint and rust. It can work well in the right setting. But after trialling it, we found serious safety concerns that every homeowner should understand before letting a laser cleaner into their property.

What is laser cleaning?

Laser cleaning uses a focused beam of light to heat and vaporise paint, rust or other coatings from a surface. There is no blast media and no water, which is why it can sound like the ideal answer for delicate work. The problem is what happens to the coating once it has been vaporised.

Why has Alberny stopped domestic laser cleaning trials?

We regularly trial new cleaning technologies. Some pass our safety tests, such as DOFF, Thermatech and soda blasting. Others fail. Laser cleaning failed for domestic use.

Our research found that laser cleaning of paint produces respirable and ultrafine particles. There is strong evidence that nanoparticles can move from the lungs into the lymph nodes and bloodstream after they are breathed in. In a home, where children and pets live, that risk is not acceptable.

We also found that laser cleaning with substandard equipment can damage the substrate and create weaknesses in wooden structures. That is a second reason we will not use it on timber beams or other wood in homes.

What happens to paint when it is laser cleaned?

The laser turns the coating into fumes and fine particles. Depending on what is being removed, these can include lead, chromium and other harmful compounds. Old paint in period homes often contains lead, so vaporising it indoors without proper containment puts everyone in the building at risk.

What safety measures does laser cleaning need?

To use laser cleaning safely indoors, you would need:

  • Fume extraction that captures vaporised particles, with HEPA and activated carbon filtration. A standard extraction unit is not enough.
  • Protective barriers to contain stray reflections.
  • Operators trained in Class 4 laser safety procedures.
  • Equipment with built-in safety circuits, proper cooling and compliance with EU electrical standards.

Are cheaper suitcase laser cleaners a risk?

Yes. Many lower cost suitcase-style units are sold without the safety features professionals rely on. They can cut corners on cooling and wiring, which may lead to overheating or electrical hazards. They often lack shielding and interlocks, leaving the operator more exposed, and they can clean unevenly, causing hot spots and damage to the surface. If a contractor offers laser cleaning in your home, ask what equipment they use and how fumes are contained.

Where will Alberny use widebeam laser cleaning?

True widebeam technology spreads the laser over a controlled, uniform area, which reduces heat stress on the surface. We are partnering with leading European built laser cleaning system companies, and we will offer widebeam laser cleaning in the South West for industrial use only. All of this work will be carried out inside our secure facility in Martock, Somerset, with every safety measure the manufacturers require. Items can be dropped off or collected, in the same way as our in-house blast room service.

What are the safer alternatives for homes?

For homes and listed buildings, we use methods that have passed our safety checks. The DOFF cleaning system uses superheated steam to remove paint from brick and stone with no dust and no chemicals. For beams, floors and other woodwork, our timber soft blast and soda blasting cleans gently, with extraction systems in place to keep the work area clear.

Conclusion

Laser cleaning has a place in industry, but not inside your home. If you want paint or grime removed from timber, brick or stone, choose a method with a proven safety record and a contractor who will explain how they protect your household.
