How do I find a good tiler? – Not using the ‘check a builder’ or ‘my trader’ websites that charge either you, or the tiler. That will end up as a cost added to the job. And you tend to find profiles get bought and sold on those websites quite easily by members saying they’ve sold the company and passed the whole assets onto the new owner, which includes the tiling profile on the website.
The best thing to do is post your job on a good tiling forum. Then checkout the people who respond to the job by checking their advice in the forum and how they’ve handled themselves when being challenged by other members.
