Cost of venting an external wall

[frazzled]

Hi,

Would anyone be able to give me an idea of the cost involved in putting a vent in an external wall?
There are none in our 18 year old house and mould has become a bit of a problem. Is it simply a case of knocking through the wall and tidying up afterwards or is it more complicated?

Thanks

you have different options..

1. vent through the wall
2. install tickle vent in the windows
3. vent into the roof cavity and out through a specil vent tile...

hire a rotary hammer action drill with a 4 inch bore from any tool hire company.Can't be any more than 50/60 per day.If your house has a cavity with insulation then drill from the outside in.Bit more mess inside but at least insulation won't be pushed away from internal wall.

drill a thin diameter pilot hole from the inside out and then drill the main holes from either side with the core bit as previously mentioned - minimal mess alternatively drill lots of small holes and chisel it out - harder . bridge the gap with some 4inch soil pipe you can seal around it with foam or cement etc. vent kits can be bought to cover the ends.
