I HAVE seen some PianoFiks pianos, but to be honest I wouldn't rate their work very highly, and it's very expensive for what you get.
The best restoration workshop in the UK, and possibly the best in Europe is www.pianorestorations.co.uk in Twyford, near Milton Keynes. They do all of their own work in-house. The only thing they don't do is a polyester finish, which they will outsource if you want it. They do all of their own action work, soundboards, stringing, felting etc, and every piano is treated with the greatest care.
They had a problem once with the lid of one of our grands and they made a new one free of charge-no questions asked.
Recommend them 100%.
Any fool can make a piano-- it needs a tuner to put the music in it
