Decorators are sometimes referred to as Painters & Decorators. Decorators carry out such work as
- sanding
- painting
- varnishing
- hanging wallpaper
The cost could be worked out based on the number of days the decorator would consider the job to take or could be more specific like a price to hang wallpaper based on the number of rolls.
Decorators may strip off the old wall paper but agree this with them before hand.
Wall paper comes in a range of finishes and qualities, it is always best to purchase the best quality you can afford.
