The reliable way to hire a tradesperson

Hi, what kind of extractor do i need to use on the grinder to extract the brick dust .been using the Henry hover, constantly getting blocked. Thanks for the help.

I would like to sound proof a party wall. Currently it is the old plasterboard. What is the best/budget friendly way to do this? I will get a plasterer in to complete but wanted to know what option has better results. I was thinking either green glue and plasterboard or mass vinyl sheet and plasterboard? Or sound coat? Any options would be greatly appreciated. I had do and dabbed soundproof plasterboard before in an old house and made no difference. Thanks

I have plasterboard joints that cracks keep showing through paint and walls are poor would it be best to line and paint walls
