Rainbow International

Damp Diagnosis &
Mould Remediation
Rainbow International are one of the UK’s
leading experts in diagnosing the causes
of damp and condensation, which can
lead to mould. A full diagnostic process is
combined with a programme to eradicate
the mould & damp problem.
Damp and mould can lead to a series of respiratory diseases
Mould is classed as a category one
risk to health, which is the same
class as asbestos, as assessed
under the Housing Health and
Safety Rating System 2000. The
Environmental Protection Act (1990)
classifies mould as a statutory
nuisance that must be treated.
The Rainbow system
incorporates a 3 stage process
when considering Damp and
Condensation issues in any
property -
Step 1 - Risk Assessment
Prior to any survey Rainbow
International will carry out a full
Risk Assessment including an
assessment of ACM (Asbestos
Containing Materials).
Step 2 - The Survey
Rainbow’s fully experienced
technical team will then carry
out a survey on the property, to
identify possible causes of damp
penetration and condensation inside
the property.

External Survey
The general state of repair will be
thoroughly assessed, including:-
n Brickwork, rendering & mortar
n Roof - condition of roof tiles or
flat roofs
n Downpipes & guttering
n Flashing around chimney stacks
and in adjoining elements
n Damp Proof Membrane - any
evidence of missing, breached
or faulty DPM
n Waste pipes
n Outside doors
n Window units (paying particular
attention to double glazed units
and any lack of ventilation)
n Airbricks - check for blockages
n Measurement of moisture,
humidity and temperature in all
building materials with hi tech
measurement equipment. This
will confirm the conditions in
the property as either damp and
at risk of mould contamination,
or dry and comfortable living
conditions.
Internal Surveys
Internally, Rainbow will check
for visible damp conditions and
evidence of mould contamination.
Damp and mould will often be
concealed within the building
structure - for example in cavities,
under floorboards and behind
skirting boards.
Wherever mould is evident, there
is usually much more of it hidden
within the building structure.
Rainbow employs a wide range of
sophisticated technical equipment
to identify and analyse the
contamination in these hidden
areas, such as Endoscopes and
Borescopes. These can have
inspection cameras attached which
allows a detailed internal visual
inspection in hard to access areas,
without major disruption or damage
to the building and its contents/
decor.
Step 3 - Remedial Action
Following the survey a full report
will be issued to the landlord,
homeowner, plumber or other
instructing party. This will provide
a complete analysis of the causes
of damp and mould, and a course
of remedial action will be proposed
which will eradicate the problem.
Upon approval of the summary of
works Rainbow will commence the
treatment, which depending upon
the nature and severity of the damp
and mould will include the following
treatments:-
n Washing, spraying or fogging
of the affected areas with
an appropriate anti-microbial
substance to sanitise the
contaminated surfaces.
n Removal of plaster and wood
where contamination is severe
or dry/wet rot has taken hold.
n Air Manager – an air sterilisation
unit which will kill all airborne
spores released from mould
Mould can thrive in a damp environment
infestation can be deployed if
necessary.
n Installation of drying equipment
regime – a combination of
dehumidifiers, airmovers &
heaters will be deployed to
ensure moisture and relative
humidity levels are introduced
that are consistent with healthy
living conditions.
n Monitoring of drying regime – to
guarantee suitable damp free
conditions are maintained.
n Installation of appropriate
ventilation systems (if
appropriate).
n Stripping out and replacing of
units and building materials that
have been affected beyond
repair by the damp or mould.
n Redecorating following cleaning
and sanitisation.
n Sign off/handover - following
treatment and drying of a
property, a certificate will be
issued which will confirm the
home is conducive to a healthy
living environment and is free
from damp and mould.
