Artex is a textured coating, and textured coatings applied before the ban frequently contained a small proportion of asbestos, usually chrysotile. That percentage is low enough that removal is normally non-licensed work and high enough that it must not be sanded, scraped dry or blasted off. The choice for most owners is between removing it properly and covering it, and the second is often the better purchase.
Test it before anything is priced
A textured coating from the right era is suspect until a laboratory says otherwise, and the analysis is cheap next to the work. Two identical looking ceilings in one house can give different results, so sample per ceiling rather than once per building. Any quote given before the result is a quote for a job nobody has defined.
What removal involves
Compliant removal keeps the material wet or uses a chemical softener, takes it off in a controlled way, and bags the waste as hazardous. The room is sheeted, the waste is consigned, and a clean is done afterwards. It is messy, slow and priced by ceiling area and access rather than by the hour, and quotes vary because some include making good the plaster underneath and some do not.
Covering instead
Overboarding a textured ceiling with plasterboard, or skimming over it, leaves the material undisturbed and gives a flat finish. It is usually cheaper, quicker and less disruptive than removal, and it is a recognised way of managing asbestos containing material in good condition. Record it, because the next person to take that ceiling down needs to know what is above the board.
Is it worth removing artex
Removal is worth it when the ceiling is damaged, when the work above it means it is coming down anyway, or when the finish has to be perfect. It is rarely worth it purely for looks when covering will do, and never worth doing badly: a scraped ceiling costs more to put right than a covered one ever cost to leave.
Questions people ask about artex removal
Does all artex contain asbestos?
No. Textured coatings made before the ban often did and later ones do not, and there is no way to tell by eye which is which. Sample it.
How much does removing asbestos artex cost?
It is priced by ceiling area, access and whether making good is included, so a single room and a whole house are different jobs. Ask each quote what happens to the plaster underneath.
Can artex be sanded?
No. Sanding, scraping dry or dry brushing a textured coating is exactly what releases fibres, and it is the reason a job that could have been routine ends up as a contaminated house.
