Existing cavity insulation concerns
Worried something may be wrong with the insulation already in your walls?
If parts of your home are difficult to keep warm, temperatures feel uneven or previous cavity work concerns you, a free Thermorite survey can help investigate accessible cavity conditions before you commit to remedial work.
Tell us what is worrying you. Thermorite will confirm eligibility and the next step.
Reasons homeowners ask Thermorite to take a closer look
SIGNAL 01
Rooms that will not stay warm
One area feels persistently colder than the rest and you want to understand what may be relevant.
SIGNAL 02
Comfort changes between seasons
Some spaces are difficult to warm in winter or become uncomfortable during warmer weather.
SIGNAL 03
Concerns about previous work
You suspect existing insulation may be incomplete, uneven or unsuitable for the property.
SIGNAL 04
Damp or mould uncertainty
You want to know whether accessible cavity conditions may be one factor among several possible causes.
SIGNAL 05
No paperwork? You can still start
A survey can begin with the symptoms you notice and anything you know about earlier work. Old documents can help, but are not required to send a request.
Visible evidence where suitable
See what is inside accessible areas of your cavity.
Where suitable, a small borescope camera can show a focused view at accessible inspection points. It may reveal cavity material, gaps, debris or other features relevant to the discussion.
Thermorite shows you what can be seen, explains what it may mean and is clear about what cannot be established from the inspected points alone.
One inspection. Four possible answers.
Your survey can lead to more than one honest answer.
No cavity work may be needed
The insulation seen at the inspected points may appear satisfactory, so no remedial cavity work may be recommended from those findings.
A localised issue may be addressed
A visible gap, obstruction or other defined concern may support a proportionate rectification discussion rather than full removal.
Extraction may be considered
Where the visible condition and wider property information support it, extraction may be discussed as part of an agreed remedial scope.
Remove and replace may be considered
If removal is justified and the cavity and property appear suitable, an appropriate new insulation option may be considered afterwards.
Look closer, carefully
The visible details matter more than assumptions.
A survey considers accessible observations alongside the information you share about the property. It does not assume one cause or a pre-selected answer.
