Cavity Wall Installation

cheggers

I am thinking about having Cavity wall installation, I've seen there are grants about, and the cost would be about £100

It is supposed to cut your heating bills by 20%, dont know how true that is?

I have a 1930s house, will Cavity Wall installation be OK? Will it lead to problems with damp and condensation??

Anyone got any tips and advise on this subject?

I've just had mine done this afternoon.

They send someone round for a survey a few weeks before its done, so you know upfront whether they can do it or not- they normaly drill into the outside wall in a couple of places.

They guys who did mine seemed to be very good and had it done in a couple of hours.

Who did you have the work done by?

Did you get a government grant for the work?

How much did it cost you?

Was there any mess?

having it installed in a 1920's detached next tuesday morning too so will see. I went via the Energy Savings Trust number and they passed my details to a local installer who worked with the grants etc. They rang and arranged a survey to measure up and check wall access. Is going to be £135 due to being a bigger than average 3 bed on wall size

It cost us £175 (our contribution) as it said on the invoice...

We went on our energy suppliers website and there was a link on there for it.

The company is called Mark Insulations (https://www..co.uk).

There was no mess as I could see, they drilled the holes, pumped in (well, it liiked like chopped up paper), then filled the holes in the wall with a mortar mix. As I said it took a couple of hours.

I think it will be a couple of days before I will be able to tell the difference, allthough I do (did) have a severe cold spot on one corner of the house and should be able to tell relatively quickly whether its made a difference.

Will keep everyone posted.....

Even British Gas do a good value scheme, for insulation.

Guess they'd be clued up on any grants available, to you.

Well worth re-doing the loft at the same time, I'd say.

I had my cavity wall insulation done at the begining of December & it is definitely worth it. The house is a lot warmer since having it done. Like you I have a 30's house. My north facing bedroom always felt a bit chilly in spite of central heating, double glazing & loft insulation, but it's quite snug now. :j

Get it done, you won't regret it & it should save you money on heating bills. I don't have to have my thermostat up so high now. I've just had a gas bill & it was lower than I'd been expecting. How I wish I'd had it done sooner. :money: :dance:

I had half of my house (the ground floor) cavity wall insulated last spring. Which sounds a bit weird.

The upstairs is covered in cladding and has no cavity due to that. I think it does still make a difference and they say warm air does rise. The new double glazing and loft insulation has helped though.

There was a hell of a lot of brick dust when they did it. Even though they swept up quite well it took months to completely wash away.

We had ours done November/December'ish last year, It is keeping us warmer, we have an outside wall in our hallway that was always cold as it was exposed - as was our Bathroom, both are now much warmer. We got ours done through a grant with warm front, the installer was very good - 1 guy on his own, took about 5 hours to do the whole house. Thay have to replace any air bricks you have and the guy who did ours managed to mix the mortar to an exact colour match - and I mean exact!!! You really have to struggle to see where the holes have been drilled.
