Mould
Moulds, their spores and their metabolites represent a significant potential health hazard in the built environment, especially for sensitive individuals. Mould growth should be unacceptable in occupied buildings.
Its presence generally indicates problems of condensation due to inadequate provision for ventilation, insulation and/or heating. Mould growth is a common problem after fire and flood. It can result in the significant loss of original material and significant delays to re-occupancy.
H+R investigate problems with mould growth in buildings, provide independent expert advice on managing the potential health problems and on preventing further mould growth.
Common Causes of Mould
Mould growth doesn’t occur spontaneously. For mould spores to multiply and create mould colonies, there must be excess moisture present. Plumbing leaks, whether from leaky pipes, overflowing sinks or faulty installations, frequently lead to mould development. For example, we advised on remedial issues for one client dealing with recurrent mould growth issues as a result of a faulty air circulation and ventilation system.
Flooding from weather events or frozen pipes can also introduce large amounts of water that can penetrate walls and materials, creating ideal conditions for mould. Even high humidity can cause condensation on surfaces, especially when there is poor insulation and ventilation since it provides the damp conditions mould needs to thrive.
Fire and flood damage are two of the most common triggers for bad mould infestations. The water used in firefighting as well as flood waters from weather events cause saturation that allows mould to take hold during the drying-out process if proper remediation does not occur.
What are the Different Types of Mould to Look Out For?
There are a few forms of mould that most commonly appear on building materials and are indicators of excess moisture.
- Cladosporium: one of the most prevalent moulds, appearing as greenish-black spots and patches on walls, floors and other surfaces.
- Aspergillus: a genus of moulds that can infest building materials and HVAC systems. It appears green, yellow, brown or black.
- Stachybotrys: known as black mould, it produces dark, slimy colonies on materials like drywall and insulation.
- Penicillium: commonly observed as a blue, green or grey mould growing in sheet-like formations on wallpaper, carpets and insulation.
- Chaetomium: olive-green and found in damp areas and on cellulose materials.
- Ulocladium: a species of black mould that looks powdery and web-like on porous materials.
Being able to identify signs of these common moulds can help track down moisture issues before the mould has a chance to extensively spread throughout the building. Please call our specialist team if you spot any suspicious mould growth to carry out a damp survey and properly identify it for the correct course of action.

Mould FAQs
-
What are the main reasons for mould growth?
-
Mould growth is caused by excess moisture, from water leaks, flooding or high humidity that introduces excess moisture. Poor ventilation and lack of air circulation allow moisture to accumulate and condense on surfaces which creates favourable conditions for mould. For this reason, kitchens and bathrooms can be common spots for mould to develop, as well as damp basements or crawl spaces.

Is it safe to tackle a mould problem by myself?

Testimonials
I have known and seen work undertaken by Hutton+Rostron for over 20 years. I have always been impressed by their professional approach and depth of knowledge in the field of building surveys and pathology.
When it comes to seeking expert advice on the condition of the timber in an old building we turn to Hutton+Rostron whom we know we can rely upon to give a thorough and efficient appraisal which we can then use to develop the scope of the repairs.
We have worked with Hutton + Rostron over many years now, and find them knowledgeable, professional, helpful and practical. They understand both the needs of historic buildings and the forces driving their alteration, which means that their expert advice is always framed in a suitable way. We greatly enjoy our relationship with them, and look forward to many more years of collaboration.
H+R have provided a great service; I’m particularly happy with the high level of technical knowledge of their staff and willingness to take time to explain what they are doing and why. I thoroughly recommend them.
Squire and Partners have worked closely with Hutton + Rostron on a number of projects, including the UNISON Headquarters and 74 St James’s Street.
We have been impressed by their depth of knowledge of historic buildings and look forward to working with them again in the future.
Having worked as Project Manager on a number of high-value, listed houses, there is in my opinion clear benefit and value to a project in having H+R on board at the earliest stage possible.
Understanding the hidden condition of a historic building is crucial in making accurate budget and programme estimations. Hutton + Rostron provide an unrivalled service in this sector allowing us to make informed decisions and mitigate the risks of historic building fabric before they materialise. Hutton + Rostron have provided input on a number of Walton Wanger projects, providing us with a range of environmental investigations, which have enabled the design process and contract negotiations to be more accurate and more robust.
Hutton + Rostron and Sandberg have enjoyed a long standing and valued professional relationship and expect this to continue and develop in the future. Our work together ranges from the routine to the quirky, with the latter often being the most fascinating and therefore enjoyable!
Now that we have reached the end of the works at Great Portland Street, I would like to thank you and your team for all your efforts. The reports on existing condition provided by the team at Hutton + Rostron were invaluable and helped us de-risk the project for GPE. Equally your assistance throughout the project where unforeseen issues arose was gratefully received.
A full service through pre-construction, construction and early occupation.
