Cavity wall insulation removal in Boston
Damp or failed cavity insulation extracted, and the real source of the water dealt with too.
Cavity wall insulation works where the wall suits it. On an exposed elevation with driving rain hitting it year after year, it can bridge the cavity it was meant to fill and carry water from the outer leaf to the inner one. Around Boston there are a lot of exposed elevations. We extract failed cavity insulation across PE21 and PE22.
What it looks like from inside
Damp patches that appear on the weather side of the house and get worse after driving rain. Cold spots and mould in corners. A tide line low on a wall that has nothing to do with rising damp. None of these proves the insulation is at fault, but together on a wind-facing wall they are worth investigating rather than redecorating over.
How extraction is done
Holes are drilled in a pattern through the mortar joints of the outer leaf and the old material is drawn out under vacuum. It is dusty, methodical work. The cavity is checked once it is clear, and the holes are made good in matching mortar so the wall is not left looking punched full of dots.
Finding what is really wetting the wall
Extraction alone is half a job if water is still getting into the outer leaf, and in this part of the county the usual culprits are above the wall rather than in it. Overflowing or split gutters soaking one strip of brickwork. A cracked downpipe. Failed pointing on an exposed gable. Lead at a roof abutment that has let go. That is our trade, so we look at all of it while we are there and tell you what is actually feeding the damp.

Cavity Wall Insulation Removal in Boston: common questions
How do I know the insulation is causing it?
From inside you often cannot. Damp that follows the weather side of the house and worsens after driving rain is the classic pattern, but we check the gutters, pointing and roof details too, because they cause the same symptoms and cost far less to fix.
Will the brickwork be left marked?
The drill holes go through the mortar joints and are made good in matching mortar. From normal viewing distance a finished job should not stand out.
Should the cavity be refilled afterwards?
Not automatically, and not on a wall that has just demonstrated it is too exposed for it. We will talk through what is sensible for your property rather than assume it has to go back.
Can you sort the gutters at the same time?
Yes, and it is usually the part that actually stops the damp. Overflowing gutters and failed lead put far more water into a wall than most people realise.
