Hi guys as ive recently got rid of my tumble dryer i now have a hole that needs filling. Its got a vent on the outside which im fie with keeping, but whats best to block the hole?

Cheers

Chris
 
bits of brick with mortar for the outside and depending on the construction on the internal surface probably a piece of plaster board with filler over the top (presuming it will be hidden and not have to look perfect)

Squirt y foam - failing that a hit and miss vent - you might need the hole again in the future :)

Then this.

There is no reason when using plasterboard to patch the hole you should get it looking 99% spot on if you take your time and sand it all out smooth.
 
If it doesn't need to be pretty then squirty foam would also be my first choice.

Make sure you block off the inside of the external vent (or remove it temporarily) so it doesn't fill with foam. Also if it's a cavity wall do something to stop tons of foam escaping into the cavity as you fill the hole. I'd wedge something like expanded polystyrene into it. In fact a few blocks of that would also be good wedged into the vent hole itself to reduce the volume of squirty stuff you'll need.
 
If it's hidden then I'd block it with kingspan out of a local skip sealed up with expanding foam, sods law says if you bricks and mortar it you'll have a need of it again within six months!
 
no ways I'd want a load of squirty foam on the outside of my house - its looks pap, and hardly and exterior grade finish!

also you don't want to be bridging the cavity (if you have one)

do it properly,

If he keeps the exterior vent as he says he is fine with doing, then surely the foam won't be seen.

This. Bricking it up will look odd/garbage anyway. You are much better off just leaving the vent.

Is expanding foam waterproof?

No but neither are bricks, that's why water gets in if your guttering is blocked and water is running down the side of your house.

Water also shouldn't get in because the vent will still be on the outside. Likewise I would be really surprised if water actually got through if it wasn't unless there was another issue like gutters.
 
Keep the cavity if you have one. I don't have a solution other than bricking up and plaster/ plasterboard over the top.
 
Many houses have vents which essentially would be the same thing. It will obviously cause a cooler spot in the wall which can cause condensation / mould as a window would do.

by that logic I'll patch up any hole with foam and stick a vent cover over it :p

I've done this for an old soil pipe outlet (similar size I imagine) and its not noticeable and has returned the wall to its previous intended construction without causing any potential problems

What I meant was that unless you have matching bricks and have the skills to shape them to fill the hole it will look odd or out of place. Given that the existing bricks will have weathered the chances of bricks matching is slim where as a vent cover just looks normal. It also gives you the option of just cutting out the foam and putting a dryer back in with very little work.
