Question 1

What is laser cleaning?

Accepted Answer

Laser cleaning (also called laser ablation) uses a high-powered pulsed laser beam to remove contaminants from surfaces. The laser energy is absorbed by the contamination — rust, paint, soot, graffiti, biological growth — which vaporises or is ejected from the surface. The underlying substrate absorbs very little energy and is left undamaged. Lightwork uses 300W and 500W pulsed fibre lasers.

Question 2

How does laser cleaning work?

Accepted Answer

The laser emits short, high-energy pulses that are absorbed by the surface contamination. The contamination heats rapidly and either vaporises, sublimates, or is mechanically ejected. Because the substrate has a different absorption profile, it is largely unaffected. The process is highly controllable — laser power, pulse frequency, and scan speed can all be adjusted to suit the specific contamination and substrate.

Question 3

Is laser cleaning safe?

Accepted Answer

Yes — for the surface being cleaned. Laser cleaning is non-abrasive and chemical-free, making it one of the safest cleaning methods available for sensitive materials. For operatives, appropriate laser safety measures are required (laser safety eyewear, controlled work area). Lightwork's team is fully trained in laser safety and all work is carried out in compliance with relevant regulations.

Question 4

What surfaces can be laser cleaned?

Accepted Answer

Laser cleaning works on metal (steel, aluminium, cast iron, bronze, copper), stone (limestone, sandstone, granite, marble, flint), brick, concrete, timber, and many composite materials. It is particularly effective on materials where abrasive or chemical methods would cause damage — thin sheet metal, heritage masonry, precision engineering components, and listed building stonework.

Question 5

Can laser cleaning remove rust?

Accepted Answer

Yes. Rust removal is one of the most common applications of laser cleaning. The laser ablates iron oxide (rust) from the steel surface without abrasion, leaving the base metal intact and ready for coating. It works on structural steelwork, machinery, vehicles, agricultural equipment, and precision components.

Question 6

Is laser rust removal better than sandblasting?

Accepted Answer

For most applications, yes. Laser rust removal is non-abrasive, produces no media waste, requires no containment, and can be used in-situ on machinery and structures without dismantling. It leaves the substrate profile intact and can be used on thin metals where sandblasting would cause distortion. For very large flat surfaces, sandblasting may still be faster, but the total cost including containment and waste disposal often makes laser competitive.

Question 7

Can laser cleaning prepare metal for welding?

Accepted Answer

Yes. Laser cleaning is an excellent surface preparation method before welding. It removes rust, mill scale, paint, and contamination from the weld zone without abrasion, leaving a clean, oxide-free surface that improves weld quality and reduces porosity. It can be applied in-situ on fabrications and structures without dismantling.

Question 8

Can you laser clean aluminium?

Accepted Answer

Yes. Aluminium can be laser cleaned to remove oxidation, paint, and contamination. The laser parameters need to be carefully set for aluminium to avoid surface damage — our 300W and 500W pulsed fibre lasers can be tuned precisely for aluminium substrates.

Question 9

Is laser cleaning approved for listed buildings?

Accepted Answer

Yes. Laser cleaning is approved for use on listed buildings, scheduled ancient monuments, and conservation areas. It is one of the few cleaning methods that meets Historic England guidance on the cleaning of historic buildings. We can provide documentation of the method and parameters used if required for planning or conservation purposes.

Question 10

Can laser cleaning remove paint from brick?

Accepted Answer

Yes. Laser cleaning removes paint, limewash, and coatings from brick and stone selectively — targeting the paint layer without affecting the masonry beneath. This is particularly valuable on heritage brickwork where abrasive or chemical methods would cause damage.

Question 11

Can laser cleaning remove graffiti from stone?

Accepted Answer

Yes. Laser graffiti removal from stone, brick, and concrete is one of our most common services. The laser removes spray paint and marker without chemicals, without abrasion, and without any risk to the substrate. It is the safest method for graffiti removal on listed buildings and heritage masonry.

Question 12

Is laser cleaning safe for flint stonework?

Accepted Answer

Yes. Flint is one of the materials we clean most frequently in East Anglia, where flint churches and buildings are common. Laser cleaning removes biological growth, pollution, and graffiti from flint surfaces without risk to the knapped or cobbled face.

Question 13

Can laser cleaning be used on classic cars?

Accepted Answer

Yes. Classic car restoration is one of our most popular services. Laser cleaning removes rust, old paint, and underseal from bodywork, chassis, and components without abrasion — preserving the original metal profile and avoiding the distortion risk of sandblasting. It is ideal for thin-gauge steel panels, aluminium trim, and precision components.

Question 14

Is laser cleaning safe for car bodywork?

Accepted Answer

Yes, when used correctly. Our 300W and 500W pulsed fibre lasers can be precisely tuned for automotive bodywork. The non-abrasive process removes rust and paint without thinning the metal or causing the surface distortion that can result from abrasive blasting.

Question 15

Can you laser clean a car engine?

Accepted Answer

Yes. Engine cleaning is a common application — removing oil, grease, carbon deposits, and surface rust from engine blocks, manifolds, cylinder heads, and components. Laser cleaning is dry and chemical-free, making it safe for precision engine components.

Question 16

Where do you cover?

Accepted Answer

Lightwork Surface Solutions covers Essex, East Anglia (Suffolk, Norfolk, Cambridgeshire), Hertfordshire, Kent, and London. We are fully mobile — our equipment is self-contained and we travel to your site. There is no minimum job size for enquiries, though travel costs apply for longer distances.

Question 17

Do you work on-site or do items need to be brought to you?

Accepted Answer

We are a fully mobile service. We bring our laser cleaning equipment to your site and work in-situ. This means machinery, vehicles, and structures do not need to be dismantled or transported — we clean them where they are. This is one of the key advantages of laser cleaning over workshop-based methods.

Question 18

How do I get a quote?

Accepted Answer

The easiest way is to send us photos of the surface you need cleaned, along with a brief description of what needs removing and your location. We can usually give an indicative quote from photos. Call us on 01376 806179 or use the quote form on our contact page.

Question 19

Do you offer free quotes?

Accepted Answer

Yes. All quotes are free and there is no obligation. Send us photos via the contact form or call 01376 806179 and we will advise on suitability and provide a quote.
