Do air bricks need to be replaced?

My airbricks weren't replaced. Should they have been? You've got me worried now.

As a qualified house builder,there is no need to replace air bricks as they are self contained the air flows through them from the outside to the loft space or under floor space the external air at no time enters the cavity space.
The cavity insulation stays inside the cavity space trapped between the internal and external walls allowing the air that is trapped there to remain at a warmer temperature than if there were no insulation in the cavity.

Yes any sleeved air bricks, the type that vent under the floor space will be ok but if you have air bricks that vent directly into the cavity these will have to be blocked up.

Best price I can get for a 3 bed semi is £150 via scottish power. Seems like because the offers have been so poppulary the prices have gone up recently.

As for the loft its £200

*****UPDATE*****

The house is definately much warmer now, with the thermostat lower than it was this time last week.

Even the cold spot we had is also warmer now.

Would recomend it to everyone.

Thanks Jason, unfortunately I just realized that I don't have cavity walls so can't have it done. But I will have the floor insulated instead as that's where the cold air is coming from.

Enjoy your warm home! :beer:

Will the installers fit new wall bricks as my mates had his house done recently and he had a few new air bricks fitted by the cavity wall installers.
