mould remediation

Mould on in service cupboard


Address: Norwich
Multi Apartment New build


Our client contacted us with an urgent request to attend their site, due to issues with moderate to severe mould evidence and ‘damp’ issues.  We responded with an urgent attendance.  This was a major apartment building in Norwich where both first and second fixes were progressing.



Our BDMA Technician carried out a full inspection, initially to deal with the growth of mould throughout the building.  Humidity levels had increased and therefore encouraged mould growth. At the time of our first visit, where we completed a full Mould Remediation Survey, it was ascertained that this mould was in evidence in different plots and communal areas, from mild to severe– in actual plots, central stairway areas and in particular in their plant rooms. 

We advised our client that these rooms, unless cleared of the existing mould urgently would have, in our opinion, resulted in a complete strip out and rebuild, in particular to the plant rooms.  We are confident that our actions on site, including mould remediation, sanitisation and continued drying, using optimum methodology, had a huge positive impact on this project in respect of both financials and time.   

The team on site, were extremely helpful by means of facilitating power supplies, areas for us to work in and listening and responding swiftly to our recommendations, for which we are grateful for.

Our Recommendations/Actions needed:

We recommended an urgent return to initially deal with the multiple areas of mould, but to prevent and maintain a mould free building, an urgent installation of drying equipment was also required, using advanced and standard equip


Mould remediation:

We returned to the site once we had the go ahead and carried out a full Mould Remediation Programme.  This included removing the mould and also applying an anti-microbial solution to all affected areas, thus discouraging further mould growth.

Coupled with dealing with the mould, we also used our Corroventa Injection Drying systems and forced anti-microbial solutions into voids, thus optimising the outcome for the client.

In respect of mould growth, RH (Relative Humidity) levels of under 60% are required to prohibit growth.  We cleared the site of mould (as to what could be seen/reached), applied anti-microbials and commenced our intensive drying programme, including the use of our advanced drying system, alongside air movement, being aware of site restrictions, both H & S and power limitations.

Damp treatment:

We found multiple areas to be wet and many of these areas had issues either with access or finishing to rooms.  This was overcome in many cases by the use of our Corraventa System injecting dessicated air (and anti-microbials) into some rooms from adjacent rooms and drying areas without disrupting finished walls/floors.  This again was to keep both financial and time delays to the client a minimum.

Drying continued with regular visits to site by our BDMA Technician so that drying could be monitored (so that reinstatement work could continue without delay once we deemed the area within suitable moisture thresholds) and also equipment could be relocated as appropriate, whilst new evidence of mould was treated also.  The mould treatment was in great need during the early weeks of our attendance/drying due to humidity levels not yet reaching their optimum level – our aim on site was to reduce humidity levels to below 60% RH as above that promotes mould growth.


This was an enormous challenge to rid the lovely new multi-apartment build of both mould and damp.  TLT are happy and confident to work with you…. no matter how large or small!  To quote one of our contacts on the project…..
