We have been quoted £400 for wallpapering (labour only) our hall, stairway & landing. Does that seem reasonable (for an average sized semi)?
Will be cowboy job
It's hard to say without seeing the room or the wall paper but it could be potentially a 2-3 day job so it's around the right price for a decorator going on the fact it's going to have awkward cuts and the wall paper has a off centred pattern to match all add time to the job.
From 350 to 400 also depending on size of the hallway and height. Also if any repair that needs doing to wall before putting up wallpaper
But if any problem make sure they are serious enough to come back and fix it
That does sound reasonable yes
