cavity insulation

Radsteral

got a knock on the door for cavity of my 3 bed semi for 149 quid... i was just about to pay 280 with eon which i signed so a bit of saving

but !!!!!!! there were 16 quailifying criterias there for a totally free work and i was laughting at my wife complaining why we always have to pay;) some aplications i done on internet for the free shower widget and socket to autoswitch appliances were the same...fre for all but us;)
i found the way for the shower widget and socket, applied for a friend of mine who is on jobseekers allowances though although i seem happy and lucky i can afford, seem the rest can just claim ''with pride'' whatever comes on way
thank god my wife was pregnant and gave birth- her teeth are being served for free;)

£280 sounds expensive. Just had my (relatively modern) 3 bed detached done for £150 by Eaga via Npower - though I had to pay an extra £30 to have a hole drilled in my wall to let more cold air in, as I occasionally use my open fire. Wish I'd kept quiet about the latter.

hello squib;)

i had the quote given for 149, reviewed and still 149 but the installer will be the same one as your one eawga or whatever called

hopefully it improves .
during the summer i changed boiler for new, tured to gas cooker, the loft is sooo fluffy;)350cm thick, that i believe not a sing;le grade of heat will escape
so this one was they only thing left before winter hits in


did they need much acces? i got the side of my semi full of shelves did they do holes every metre or further to 1 m?

Hi - I also had a more expensive quote from Tesco, but the Eaga guy said the job may have come their way anyway. Sounds like although there are loads of people selling cavity insulation, there aren't that many companies actually doing the work.

I've also had my aged leaking boiler replaced this summer, and switched my electric & gas supplier for the first time ever. Part of the loft has also finally been boarded and some more insulation installed. I'm actually looking forward to winter to see if all the changes do actually result in a more comfortable house, and lighter bills!

Apart from when they drilled the vent in the living room, no access was required to walls inside. I have a garage on the side of the house, so had to shift most of the stuff away from the shared wall, except for a small freezer and tumble drier. They worked around those, and I guess on average the holes were around 1.5 metres apart. Underneath the lounge window, I have a dense bush with vicious thorns. They said I'd need to lose the bush if that bit was to be done, or they'd just omit that small section. I opted for the latter.

I played safe and removed a few pictures and items off shelves, as their instructions warned that the vibration could cause something to fall. In practice, it wasn't too bad - the only vibration which caused an item to vibrate off a shelf, was when they drilled the large vent hole in the living room.

I heard some scare stories about the main drilling causing damage to bricks. When I asked the estimator, he told me they had 3 drill sizes. If I remember correctly, these were 19mm 22mm & 25mm. The smallest wasn't an option at the standard price and was going to be hundreds extra, so was a non-starter. He said he'd make a note that I preferred 22mm. I double checked with the guys on the day and they were using the 22mm option. This worked fine on my walls, the holes were drilled in the T-shape where three bricks met, and I was perfectly happy with the job. You can see the patched up holes if you go looking for them, but they are not very noticeable.

I had my house done earlier this year.
£99 from Mark Group.

Very tidy and very little disturbance.

Just been cold-called by EAGA and assessed. Quote is £129 for cavity wall insulation (as the area is below 140m2).

The house is 7 years old and the assessor said there was a minimum amount of insulation - a 20mm board, but the cavity is 95mm so it's still worth getting done.

I see a figure of 33% saving on heating costs after insulation banded around but does anyone know how effective the 20mm board will be and what sort of improvement full cavity insulation will achieve?

Hi, I'm new so apologies if this isn't the right place to ask! We're basically considering cavity wall insulation for ourselves and for my parents. Does anyone know of or have used a company called 'HIS insulation' who are based in the Midlands or Domestic and General Insulation Ltd? We're a bit worried of any cowboy companies so would appreciate any input/feedback from anyone with regards to these two companies. We got quoted £129 from HIS and £159 from Domestic and General for bonded beading insulation and we were going to go with HIS (as it's cheaper) and book the appointment this week to have the work done but we needed some reassurance as to whether we have chosen a reputable company or not. We have a 3 bed end terrace in Bristol and my parents a 3 bed semi-detached in Birmingham. Parents are over 70 so it should be free to have this work done. Another thing that worries us is to hear that some people experience damp/condensation in their houses after they've had this done. What's the likelihood of this? Any advice on this would be great thanks!

Is there a product or cavity insulation service available yet for the older kit houses?

Hi DNA_628
Please consider seeing my previous posts regarding cavity wall insulation & cavity wall ties (the latter to be considered prior to cavity wall insulation work) - the vast majority of homes that are cavity wall insulated after they have been built do not suffer chronic dampness problems but there are those that do and this primarily comes down to material used to insulate, the condition of the wall cavity, the construction of the cavity wall (especially mortar re-pointing and external finishes), property type, location and exposure of the property. The least problematic materials from a dampness point of view in my experience are the polystyrene ball / chip.

I would strongly recommend the cavity wall ties be assessed prior to any cavity wall insulation work especially if you are going to own the property for a significant period after the cavity insulation has been fitted. Addressing cavity wall ties after the insulation is fitted is considerably more difficult.

If the house has any current problems of dampness these want properly investigating as to the cause before considering cavity insulation and any debris within the cavity including at base of walls / on lintels over openings should be removed prior to such work. kindest regards, David Aldred Independent damp, timber and cavity wall tie surveyor

What do you mean by 'older kit houses'?
If you mean houses that do not have cavity walls, then the answer is fairly obvious...

I knew the vagueness of my post would be a problem. I'm not technical in the slightest but it was my understanding that between the bricks and the plasterboard there was spaces that are part filled with insulation.

When the chaps came out to do the cavity wall work at my folks which did have a cavity they said that they were developing some foam based product that will be suitable for kit houses that would work along with older wool insulation........ I now assume he was talking nonsense??
