I have always been told that retrofit is a bit hit and miss, however I would like to also say that I think that would be down to the level of care and professionalism that the installers applied to your property.
One company who have done work recently for a customer of mine, and their work was brilliant, is Simply Pools. http://www.simplypoolsspain.com/
It would not be fair for me to personally recommend them as I have never done business with them, however, my customer is a very satisfied client based on their work.
I hope that helps
