Mould Removal & Remediation in Swansea & South Wales
Mould is water before it is anything else. We assess the premises free of charge, find where the moisture is coming from, remove and treat the growth, dry the fabric properly, and put in writing what has to change so it does not come back.

What Mould Removal and Remediation Involve
Mould removal is the physical removal and treatment of mould growth from a surface. Mould remediation is the wider job: identifying the moisture source that is feeding the growth, removing what cannot be treated, drying the structure and correcting the conditions that allowed it. Treating growth without dealing with the water behind it is decoration, and it fails, usually within a few months.
CrewConnect carries out mould removal in Swansea and across South Wales for landlords and letting agents, managing agents, registered social landlords, facilities and office managers, employers and property owners. Workplaces, let property, void units, storage areas and commercial premises. The assessment is free, the findings are written down, and the price is agreed before anything is treated.
The Mould Removal and Remediation We Carry Out
Site assessment and source identification
Moisture readings across the affected areas, the growth mapped, and the likely source identified: a leak, a failed seal or flashing, rising or penetrating damp, cold bridging, or condensation from ventilation and heating that is not doing its job. We use moisture meters and thermal imaging where it is needed to find hidden damp behind walls and above ceilings.
Mould removal and surface treatment
Growth removed under controlled conditions rather than brushed off, with filtered extraction so spores are contained rather than distributed, and surfaces treated with a fungicidal biocide to the manufacturer's contact time.
Contaminated material removal
Porous material that has absorbed contamination, including affected plasterboard, insulation, soft coverings and stored goods, removed rather than treated in place.
Drying and remediation
The fabric dried out and monitored, because a surface that reads damp will grow again whatever it has been treated with. Drying time is part of the programme.
Workplaces and commercial premises
Storage areas, plant rooms, washrooms, kitchens, cellars and back-of-house spaces, worked out of hours where a shutdown is not an option, alongside our commercial cleaning crews.
Let property, voids and reported complaints
Mould reported by an occupier, or found at check-out on an end of tenancy turnaround, assessed and documented so you hold a dated record of what was found and done.

Why Landlords, Agents and Employers Choose CrewConnect
Mould is a compliance matter as much as a cleaning one. Under the Workplace (Health, Safety and Welfare) Regulations 1992 an employer must keep the workplace and its fittings sufficiently clean. In Wales, the Renting Homes (Wales) Act 2016 requires a rented dwelling to be fit for human habitation, and the regulations under it list damp and mould growth among the 29 matters used to judge fitness. BS 5250, the British Standard covering the management of moisture in buildings, approaches surface mould as a moisture problem to be controlled at source rather than a surface to be cleaned.
That is why our first visit is an assessment with a moisture meter rather than a quote written off a photograph. Every crew member is DBS-checked, which matters in occupied premises and let property. Our health and safety management is independently assessed under SafeContractor, and CrewConnect is veteran-owned, with the discipline that brings.

Transparent pricing
What a Mould Removal Quote Includes
Mould is priced from the assessment, because the visible growth is rarely the whole job. The written quote sets out:
Property management companies handling multiple units are quoted on contract rates rather than job by job, so the same terms apply across the portfolio.
The site assessment is free and carries no obligation. If the scope changes once material comes off, the revised price is confirmed in writing before we carry on.

Frequently asked questions
How much does professional mould removal cost?+
It depends on the area affected, whether the source is accessible, and how much material has to be removed rather than treated. As a general guide, UK mould removal is commonly quoted from around £180 to £800 for a single room, and from £800 upwards where a whole property is affected. Our site assessment is free, and the price for your premises is written down before we start.
Is mould removal the landlord's or the tenant's responsibility?+
Where the mould follows a building defect, disrepair, or condensation caused by inadequate ventilation or heating, it sits with the landlord. In Wales, the Renting Homes (Wales) Act 2016 requires a rented dwelling to be fit for human habitation, and the regulations list damp and mould growth among the 29 matters used to judge that. Our written assessment records what was found, which usually settles the question.
Is mould dangerous to health?+
It is treated as a hazard rather than a cosmetic problem. Exposure to damp and mould is associated with respiratory symptoms, and it affects people with asthma or a weakened immune system more than most. The practical point matters more than the alarm: mould is the visible sign of a moisture problem, and both the growth and the water behind it need dealing with.
Will mould come back after removal?+
Not if the moisture goes with it. Mould needs water, and it returns to any surface that stays damp, which is why treatment on its own fails. We identify the source during the assessment, remove and treat the growth, dry the fabric properly and set out plainly what has to change, whether that is a repair, better ventilation or a heating pattern.
Do you treat the cause of the mould or just remove it?+
Both, as far as the cause is a cleaning and drying matter. We take moisture readings, identify where the water is coming from, remove and treat the growth and dry the structure out. Where the source is a building defect, a failed seal, a leak or missing ventilation, it goes in the written report for your contractor or maintenance team to put right.
How long does mould removal take?+
A single affected room is usually a day. Larger areas, or anything requiring removal of contaminated material and a proper drying period, run across several days, because drying takes the time it takes and cannot be hurried. The assessment gives you the duration before you commit, along with what can be done while the premises stays in use.
Do you offer free mould surveys or assessments?+
Yes. We attend, take moisture readings, use thermal imaging where hidden damp is suspected, map the affected areas, identify the likely source and give you a written assessment and price at no charge and no obligation. For a landlord or an agent responding to a reported complaint, that assessment doubles as a dated record of what was found and when.
Can you just paint over mould?+
Mould-resistant paint covers growth without removing it and does nothing about the water feeding it. The growth continues behind the coating and comes back through, usually within months, and the second job costs more than the first would have. The order that works is: remove the growth, treat the surface, dry the structure, then decorate.
