Swimming pool refurbishment

I wouldn't use Copil. They did a small job on some steps and were supposed to put on some missing dark blue tiles, but ended up putting on a lighter colour. They also had to come back 2 or 3 times to sort out the grouting and still didn't change the wrong colour tiles. I have never had Poolology back after doing work for me. They are fully insured and all work is guaranteed upto 5 years.
