So, even where a surveyor is unable
to view the cavity and identify any
voids, rubble or other issues, a
judgement can be made on the
performance of the CWI. With
reference to technical documents (e.g.
BBA system certificate), the subsequent
report can direct home buyers
with specific advice. Even where the
is the ‘ECO’ stampede. Installers
rushed to fill as many cavity walls,
as quickly as possible with disregard
for the suitability of properties. The
role of the guarantee agency CIGA
in this and their current approach to
‘CWI claims’ has been discussed at
government level. Indeed, the Cavity

internal ‘making good’ works were
carried out. Unfortunately, whilst
there are many good contractors now
carrying out these extractions, there
are also poor examples, including
those by contractors who prospered
filling the cavities in the first place.
CWI may seem to be performing
without any problems, home buyers
will often request guidance on living
with CWI now and in the future.
Where the surveyor suspects that
CWI has been incorrectly installed,
intrusive investigations will then
need to be carried out to establish a
clear cause. It is always surprising as
to what is present within a cavity, or
more likely, what is not there. One
of the main causes of failed CWI in
residential properties in recent years
(CIVALLI) continue to campaign
against poor CWI installations and
support those people affected.
Finally, residential surveyors are now
also being faced with properties that
have now had CWI extracted. A considerable
amount of disruption can
often be found to external walls and
a surveyor will need to make specific
enquiries in relation to the removal
of any CWI. This should include
whether the extraction was independently
verified and what, if any,
Even where the CWI may seem to
be performing without any
problems, home buyers will often
request guidance on living with
CWI now and in the future.
