Hi, would really appreciate some advice. I need to remove the warm air vents from our upstairs ceilings and was wondering how the professionals might tackle this. We have a 70's house and all the ceilings are covered in the speckled effect artex ( I assume it is artex? ). Removing the vents (four bedrooms, landing and bathroom) will leave holes. I can board over these from inside the loft but would a professional artexer/plasterer be able to cover this and match in with the existing artex, or would we need to completely skim over the ceiling. Somebody told me the existing artex might contain asbestos? and that we might have to replace the ceilings which seems a little severe. Thanks
