So we had work done in our property last year by a local checkatrade approved builder. Last night (without outing myself with the details) the shit hit the fan and our house flooded. We've had repair people in who have said that the work was seriously unsafe and no doubt caused the problem. We now want to chase the builder for a refund to cover costs of damages but his website has gone, no longer on checkatrade and not picking up his phone. We have his address that the company was advertised as but I sense now he's gone. We've been advised by citizens advice to write a letter to the address threatening legal action if he doesn't refund what we need to fix it. But this is just going to fall on deaf ears isn't it??
What can I do??
