Advice on Cavity Wall insulation

The damp, problems was most likely a condensation problem. The warmer walls did not allow condensation to form.

Rockwarm did my 3 bed semi about six weeks ago, for the sum of £175. There are grants available from central government for the balance of the cost (£305 in total) which Rockwarm claim directly.

The installation took about half a day, they used "rockwool" and the effect was almost immediately apparent. The only drawback we have noticed is that the condensation problem we were already suffering from - due to poor ventilation - is worse on the windows, though obviously not as bad on the walls.

It was but has fallen out of favour, as the polystyrene damages PVC cabling in the cavity and can cause nasty occurrences. If the cabling isnt in the cavity theres no problem.

Can cavity insulation be put into ratbond brickwork?

Had the gentleman arrive as promised today and within 20 seconds he said I didn't need it, as it already had been done. He pointed out the locations, which to be honest I didn't notice.

I apologised for wasting his time, and would have had it installed had I needed it. Ahh well I'll have to spend that money on getting the gas boiler serviced and thermostats fitted to ensure we don't waste too much energy.

I had my Victor Meldrew moment, not about the cavity wall insulation company, but my moron of a surveyor (£800 odd for information you can't rely on) who managed to miss out on the cavity wall being present and recommending that I have it fitted to improve my energy efficiency. Not only that I ended up paying for a structural surveyor for work that was evidently wasn't required and for which the local BCO had signed off as being suitable.

If you had seen our bricks... not that I'm saying the mortar wasn't at fault as well, but the bricks are dreadful, spogne-like, soft things.

It certainly wasn't condensation - it was rainwater. It came in along the tops of the windows in quite some quantity whenever it was raining, whether or not you were having a bath / doing some cooking, and whatever the temperature.

Hwyl!

They may soak up water easily, but to penetrate all the way through you would need prolonged driving rain.
