Damp walls, mould or a failed survey caused by old cavity insulation? We extract it, inspect the cavity with a camera, and refill it properly, or tell you straight if it shouldn't be refilled.

A lot of Scottish homes had their cavities filled in the 1980s, 90s and 2000s, some of them by firms that never checked whether the walls were suitable. On exposed sites with driving rain, or where the outer brick or pointing was already letting water in, older fibre fills can soak up moisture, slump and bridge the cavity. Water then tracks across to the inside wall.
The result is damp patches, black mould behind furniture, cold spots and sometimes a mortgage valuation or survey that flags the insulation. None of that goes away on its own.
We look inside the wall, find out what was used and where it's failed, and work out what's causing the damp.
The old material is pulled out with specialist vacuum equipment through openings in the outer wall, bagged and taken away.
Camera back in to make sure it's clear, including debris at the base that can bridge the cavity.
Pointing or render repaired where needed, then refilled with modern beads that don't hold water. Or, if the wall shouldn't be refilled, made good and we'll talk you through the alternatives.
Not every damp wall is the insulation's fault. Gutters, downpipes, failed pointing and condensation cause a lot of it too. We'll tell you what we find, even if the answer isn't extraction. You shouldn't pay to rip out insulation that isn't the problem.
We cover Edinburgh and the Lothians, Fife, Glasgow, Stirling, Perth, Dundee, Aberdeen, the Borders and the Highlands. Every job starts with a free survey.
Signs include damp patches or black mould on inside walls that weren't there before, cold spots, and a survey or mortgage valuation flagging the fill. Old fibre insulation can slump and hold water, especially on exposed walls.
The old material is pulled out of the cavity with specialist vacuum extraction equipment, through openings in the outer wall. We then check inside with a camera to confirm the cavity is clear before refilling or making good.
Usually yes, with modern beads, once the cause of the damp is fixed. If the wall isn't suitable for refilling, we'll tell you and discuss internal wall insulation instead.
Most houses take one to three days depending on the wall area and what's in the cavity.
Removal itself usually isn't, but refilling a failed cavity may be for eligible households. We'll check what applies to you.
