    Freezing house- have been told there is cavity insulation but I'm not sure...

    Can anybody advise pretty please ?

    I live in a 70's bungalow, we had airbricks fitted when we moved in as it was advised in the survey ( suspended timber floor)

    Had a surveyor come to check if we could get the government funded cavity wall insulation, they said we already have it (proof being some small cement filled holes at the front of the house ) but I can't help feel that the cavity isn't filled. The heat just doesn't stay in the house (we have plenty loft insulation). Plus- when the builder fitted the airbricks, wouldn't all the cavity wall stuff have fallen out.... ??

    Wish I knew more about building and what not and I'm terrible!! Any advice most welcome. x

    Drill a hole through the brick, from inside to out.( put a square inch of cello tape on the area you plan to drill, this will minimise damage to interior decoration.)

    If you have insulation, you will have a pile of paper mache/polystyrene balls on your living room floor, you me need a top up.

    If not, you will have a hole which lets the elements flow through your home.

    Risky I know, but your mind will be at peace. ( take pictures for evidence, will come in handy when selling your home)

    Let me know how you get on (_;)

    If you have any air bricks, you could try and remove one and then use a mirror and a torch to look up inside the cavity and see if it's filled.

    Awaits the thread "Hole in my wall, what do I use to fill it"... X)

    Or ... How do I repair the cable I just drilled through?


    Get into the loft with a mirror and a torch and you will be able to see into the cavity without drilling holes

    Cavity wall insulation doesn't heat the house up, it only keeps it warm once it has been warmed up - like putting a big jacket on.

    Does your heating work ok and do all the radiators heat up ok? Any gaps around windows/doors

    Have you tried to temporarily block the air bricks to see if that makes any difference. Maybe too many were added and you now have draughts rising up through your floors chilling the house and letting hot air escape ?
    Im surprised a bungalow was initially built without enough air bricks in the first place.

    Thankyou kindly for your replies! : )

    I'll have a look in the loft when we get the tree down this weekend, and find something to block up some airbricks temporarily to see what happpens.

    mjccam, thanks, the heating is in good working order (quite new boiler) all radiators get up to about 75 degrees which I think is normal. Most windows are good quite new condition, have thick thermal curtains at the one which seems draughty.

    Type your answer here...Presume the suspended timber floor is above a solid concrete floor and that is why airbricks were
    fitted?.

    As mosskeeto suggests the easiest option is to check the cavity from the loft first, check all the cavity walls.

    Get in touch with your local council. They will have the names of approved Insulation companies.
    They can visit the house and check the Loft Insulation & cavity wall for free.

    And if anything needs doing they will let you know of any grants available

    dont block up airbricks unless you want damp! they are there for a reason.

    also, drill a hole through the pointing, not a brick as you wont notice the hole once re-filled (unlike in a brick)

    We had a cold house and had cavity wall insulation already done by previous owners. I manged to get someone out and they told me the cavity wall insulation had failed (not done properly). I was able to get it fixed under the 25year guarantee even though the company was no longer trading. Have a look on this website you might come across something yourself.

    Thanks Poppy that's really good advice. Only problem being previous owners didn't leave a guarantee... I think my only option would be to ring round any installers in the area to ask if the house is on their database of work done..

    Also.. when the cavity was filled, would they have filled it from just the front wall of the house? That's the only wall with small holes evident.

    If you give CIGA a call you might be able to use your postcode and house number. If they have you on the database then they will be able to look into it for you.

    I think they should go all around the house not just the front.
