I've just had the cavity wall insulation done on my house (it's a three bed semi) and I was wondering if anyone else had had this done and knew the time it took as they seemed to do the job in under four hours with a team of two.
I was watching the Rockwool as it travelled down the pipe and it looked like it was sporadically churning out a few feathers when it felt like it. I couldn't see how this would fill the cavity! :shock:
The house doesn't seem any warmer that's for sure... :?
My parents had the house done recently, i cant comment on how long it took, but i remember it being very noticibly warmer (from wearing a jumper to now having too).
I would query it with them, put your mind at rest
I don't want to talk to them as the first time they came they nearly burnt the house down because they were using American equipment with the wrong amperage and they nearly burnt the house down as the plug was smoking like Wolverine at the bar. :roll:
This is their second visit and they reckon they do three houses a day. My mate had his done and it took all day and he has only two walls to fill as his house has two houses either side. That's why I queried.
I had mine done (similar sized house). It was the middle of last year, so I'm relying on addled memory. I'd say it took them maybe half a day - something like that. Very busy with drills and stuff, as Ross mentioned, it was little beads (according to the people I spoke to on the phone - which is quite likely blag - it's the latest stuff...).
They put in several vent bricks in certain parts, too - they seemed reasonably thorough in that they checked out the rooms, I guess they have things to look for, criteria wise.
Over the warmer months and autumn I wanted to think the house was definitely warmer - although in the depths of winter, it's hard to say. Relatives all seem to approve, and say they've been happy and felt the benefit. Dunno whether that's just some choice-supportive bias, or whether there's really something to it.
Like most, I asssume, I got it done because it was free (to me) and at least has the potential to save me money.
As to the time they took, given what I remember (which you wouldn't truly rely on...) they took a fair few hours - I could imagine them being able to do two of the size / type of houses like mine, in a day - three would seem ambitious unless they do quite long hours. I seem to recall they started reasonably early, though. Perhaps with smaller houses, like terraced houses, maybe it takes less time, and maybe with a larger detached would take a fair bit more. I was reasonably happy with the job they did, bearing in mind it was free to me, and they seemed reasonably thorough, and what they did looked very neat. I was working at home as they did it, so could hear all the times they were drilling and pumping stuff in. The only evidence from the outside, that you could tell they were there, is from some newer vent bricks - which were done very neatly, including the interior vents, and if you looked really closely, you may be able to tell where they drilled, but from the fabled 5-yard-stare (where cars look fine, until you get a lot closer...) you'd probably never notice anything that suggested it had ever been done.
