Cavity wall insulation surveys in Northern Ireland
Cavity wall insulation surveys across Northern Ireland.
What cavity wall insulation surveys involves
A cavity wall insulation survey looks inside the gap between the two leaves of a cavity-built wall to establish what, if anything, is filling it. The specialist drills small holes at agreed points, feeds a camera through them and records whether the cavity holds bead, mineral wool, spray foam or nothing at all, along with the state of what is there.
It suits buyers whose lender or home survey has flagged the wall, owners with cold or damp internal walls, and anyone who has been told insulation was installed years ago but has no record of it. Book the survey at the price shown, choose a date, and the findings come back in writing.

How cavity wall insulation surveys works with us
Slot chosen
You book the cavity survey at the published price and pick a date, giving the address and any detail about when insulation was fitted.
Holes drilled
Inspection points are marked at set spacings along each elevation and small holes are drilled through the outer leaf.
Camera inspection
A camera on a rod passes through each hole so the specialist can see the insulation, the cavity and the inner faces of the wall.
Written report
Every hole is filled, and the findings, photographs and any recommended next steps arrive in writing.
Does this look like your roof?
- A lender, valuer or home survey asks for the cavity to be investigated
- Internal walls that stay cold to the touch even with the heating running
- Damp staining at skirting level or a musty smell in one room
- Small beads or loose fibres appearing at an air brick, vent or wall base
- Insulation was installed by a previous owner and no paperwork survives
- The outer leaf stays wet long after rain, or mortar has washed out of the joints

Points the specialist works through
What the cavity usually holds
Bead, mineral wool, spray foam and loose fill all turn up in Northern Ireland walls, and some cavities were never filled at all. The specialist records which material is present, how evenly it sits and whether it reaches the top of the wall.
Foam in a cavity and what lenders ask
Where spray foam has been injected, a lender or valuer may want detail before lending. The written record sets out the foam type, its extent and the condition of the wall, so the question can be answered with evidence rather than guesswork.
Wet insulation and the wall around it
Insulation that has taken in water loses much of its value and can keep the inner leaf damp. The specialist notes any sign of moisture, along with defects on the outer leaf that could be letting rain in.
How the holes are made good
Each inspection point is drilled at a set spacing, kept small, and filled with matching mortar once the camera has been withdrawn. The report lists where the holes were made.
