Cold rooms, existing insulation or an unknown wall cavity?
If earlier cavity work does not feel right, start with the rooms, history and visible details you have noticed. A free property-specific survey helps make the next conversation clearer.
Free survey • Camera inspection where suitable • The findings may indicate that no cavity work is needed.
Existing insulation
Concerned About Existing Insulation?
Where suitable, Thermorite can inspect accessible points and explain the visible findings.
Free, no-obligation survey
Complete the short form, add your postcode and tell us what you have noticed. If a survey could help, we'll get in touch. Afterwards, you'll have a clear report of the accessible findings—and what happens next is entirely up to you.
Add your postcode and the few details you know. It only takes a minute to get things started.
We'll check whether your postcode is within the advertised survey area and read through your request.
If a survey could be the right next step, we'll contact you using the option you prefer and agree a time that works for you.
After a survey, we'll provide a straightforward report of the accessible findings. It is free, with no obligation to take up any Thermorite services.
Start with what you know
You do not need to diagnose the problem before asking for a survey. Choose the starting point that feels closest to your situation, then tell Thermorite what you have noticed.
Perhaps it was installed years ago or before you bought the property. You may have paperwork, or only a rough memory of earlier work. Rooms may still feel cold, temperatures may be uneven, or you may be worried the existing insulation needs checking.
Check my existing insulationYou may have moved in without paperwork, found old drill holes, or simply not know whether cavity insulation has ever been installed. Thermorite can investigate what is visible where access is suitable.
Find out what’s in my wallsCould your cavity insulation be part of the problem?
These symptoms do not prove that cavity insulation is the cause. They are sensible reasons to ask for a property-specific survey rather than guess or commit to work too early.
SIGNAL 01
One room or side of the house is noticeably harder to heat than the rest.
SIGNAL 02
You have noticed damp patches, particularly on external walls or around openings.
SIGNAL 03
Mould has appeared where a room or wall remains unusually cold and you want to understand what may be relevant.
SIGNAL 04
Different areas of a wall or room feel noticeably different from each other.
SIGNAL 05
You have found old drill holes, paperwork or other signs that insulation may have been installed before.
SIGNAL 06
You bought the property and do not know what, if anything, is inside the cavity.
See inside the wall where suitable
Where suitable, a small borescope camera can inspect accessible areas of the cavity. Thermorite explains what can be seen at those points—not simply that you need work.
Accessible view 01
Visible gaps or inconsistent material may be relevant to the discussion.
Accessible view 02
The visible condition of existing material can be discussed where it is accessible to inspect.
Accessible view 03
Rubble or other obstructions may be visible at an inspection point and considered in the assessment.
Accessible view 04
The inspection may show material that appears evenly distributed at the points viewed.
Evidence before extraction
Some existing insulation may appear satisfactory at the points inspected. Some properties may have a localised issue. Some may need a discussion about removing existing material—and sometimes the problem may not be the cavity insulation at all.
Thermorite’s job is to investigate first and recommend work only where the property findings support it. That gives you a clearer basis for deciding what happens next.
One inspection. Four possible answers.
The result remains specific to accessible findings and the wider property information. It may lead to one of four conversations.
The insulation seen at the inspected points may appear satisfactory, so no remedial cavity work may be recommended from those findings.
A visible gap, obstruction or other defined concern may support a proportionate rectification discussion rather than full removal.
Where the visible condition and wider property information support it, extraction may be discussed as part of an agreed remedial scope.
If removal is justified and the cavity and property appear suitable, an appropriate new insulation option may be considered afterwards.
