My chimney mounted aerial pole is loose-ish and is rubbinmg / eating into the chimney brickwork. The aerial is old and probably could do with something more modern. The wire from the aerial is brittle and shot.
So... How much should I pay for...
1. New Aerial (freeview capable)
2. New lashings for current pole
3. Cable replaced to rear bedroom
4. Cable replaced to front room
5. Fitting of above
Currently been quoted £120-£150. Is this reasonable?
Hard to say, because each job is different, but if it includes the bits, then it doesn't sound unreasonable. Personally, I would avoid chimney mountings unless it's unavoidable, because chimneys are incredibly weak structures. I prefer a good solid wall mount with Rawlbolts.
