Locus Services removes mould from commercial and industrial buildings: warehouses, cold stores, chemical stores, plant rooms, food sites and offices. Our crews work in full PPE, clean the growth off, disinfect the surfaces and tell you what is feeding the damp, so it doesn't come straight back. Every job starts with a free site survey.

Mould removal for commercial buildings

Mould grows wherever moisture sits: condensation in cold stores and unheated stores, water from a leaking roof or gutter, or a plant room or basement with poor ventilation. On a commercial site it’s more than a stain. It can spoil stock and packaging, mark walls and ceilings, count against you in a hygiene audit and make an area unpleasant to work in.

Locus Services cleans mould off walls, ceilings, panels and fixtures, disinfects the area and leaves it ready to use. Where surfaces have reached the end of their life, we can repaint or refurbish them as part of the same job.

Where we remove mould

AreaWhere mould growsWhat we do
Cold stores and chillersPanels, ceilings, door seals and around the evaporator units, where humidity is highClean and disinfect from floor to ceiling, around the plant, with seals cleaned by hand. See cold store cleaning
Chemical stores and storeroomsBlock walls and ceilings in rooms with little ventilationClean the growth off, disinfect, and repaint if the surface needs it
Warehouses and factoriesHigh walls, roof steelwork and cladding joints where condensation formsClean from MEWPs, one zone at a time. See warehouse and factory cleaning
Plant rooms, basements and voidsDamp walls, ducting and tanksWork to a confined space plan where needed. See confined space cleaning
Food and drink sitesCeilings and walls in preparation and storage areasPlan the work around production and your hygiene rules
Offices and public buildingsWalls, ceilings and window reveals in damp roomsWork out of hours, so the rooms are back in use the next day

How we remove mould

  1. Survey. We look at how far the mould has spread, the surfaces it’s on and what is causing the damp, then send a written quote.
  2. Protect. We close off the area and move or cover stock and equipment. Our crews wear full PPE, including respirators.
  3. Remove. We clean the growth off using methods that suit the surface, with dust control so spores aren’t spread around the building.
  4. Disinfect. We treat the cleaned surfaces and the area around them.
  5. Clear the waste. We take contaminated materials away as a registered waste carrier (CBDU320327).
  6. Report back. We tell you what we found and what’s likely to be causing it, such as a leak, condensation, poor ventilation or failed insulation, so the cause can be fixed.

Why mould matters on a commercial site

  • Health. The HSE lists fungi among the biological agents that can harm workers, and the COSHH Regulations are the main law for controlling exposure to them at work.
  • Disturbing it spreads it. The HSE notes that Aspergillus, a common indoor mould, can release spores when it’s disturbed, and recommends dust control and properly maintained ventilation.
  • Food hygiene. Food hygiene law (Regulation 852/2004, Annex II) requires ceilings in food rooms to reduce condensation and the growth of undesirable mould.
  • Stock and the building. Mould marks packaging and finishes, and the damp behind it can damage the fabric of the building over time.

Frequently asked questions

Is black mould dangerous?

It can be. The HSE says most healthy people aren’t affected by common indoor moulds, but people with damaged lungs or a weakened immune system are at greater risk if they breathe in the spores. Disturbing mould releases spores, so we remove it with dust control and in full PPE, and keep the area closed off while we work.

Will the mould come back?

It will if the damp is still there. We clean and disinfect the surfaces, then tell you what we found: a leak, condensation, poor ventilation or failed insulation. Once the cause is fixed, the area should stay clear.

Can you work around our operations?

Yes. We work 24/7, so we can clean at night, at weekends or in sections, and close off each area while we work. In cold stores we usually work in sections as stock is moved.

Can you clean mould at height?

Yes. Our IPAF-trained operatives clean high walls, ceilings and steelwork from MEWPs, with the area below closed off.

Do you provide risk assessments and method statements?

Yes. Every job has its own risk assessment and method statement, written after the site survey.

How much does mould removal cost?

It depends on how far the mould has spread, the surfaces, access and when we can work. We give a fixed written quote after a free site survey.
