Good availability — work was done at the weekend at a convenient time, and the contractor called 20 minutes before arrival to confirm his (prompt) arrival.
TV was mounted at the height requested with good quality components and a minimum of a mess. Cables were threaded in the wall with threading boxes at the bottom and top for a quality finish. Work took around 90 minutes.
Contractor was very professional, vacuumed up any mess, and gave a quick demo of how to use the mount.
Wall mounted a flat panel tv, and hid the cables in the wall.
