Missing insulation in cavity wall

bennb229

It has become apparent during building work that our house is missing around 60% of its insulation, there are large cavities with no insulation and most of the top of the house has none in at all! my collegue said he had a similar issue and the company would not insulate his house because it was part filled, is this still the case? What other options are there? Can I do it myself? and at what cost?

For some time we've been offered the chance of free cavity wall insulation, but have turned it down because we knew our 35 year old house had been built with cavity wall insulation included.


However free scheme has now been extended to include replacement insulation. It was explained to us that the insulation crumbles and falls to the bottom of the walls over the years and local Council would now fund the removal of this old insulation and replacement with new.


We took up the offer and had the work done. Large holes (saucer size) were drilled around the house walls near ground level, the old insulation was vacuumed out. Masses of new small holes were drilled on walls and new insulation piped in.


I should warn you, though, that this was a messy process. Company sealed around inside of all windows and any pipe entry points, but still some dust came into house. Ground around the house looked like a grey coloured snowfall and had to be pressured washed clean.


We were assured that the work would be invisible, filled in with matching coloured harling, however, although the mass of small holes were covered successfully, the large recovered saucer size holes are still noticeable - perhaps they will 'weather in' over the years.


Now that the work has been done we're glad that we accepted the offer.
