Hi everyone, thank you for your replies, I’m not interested in chasing him for the costs and time that I’ve had to incur, but I will counter claim if he proceeds as it seems to be the only way to defend myself.
We have spoken by email about the issues and got nowhere, with him claiming that as the overall costs of the devis are similar we should be paying for it all.
We see it as we didn’t get the goods that were quoted for in the original devis and that he didn’t bother doing the extra work or discuss with me doing or not doing so.
I also needed the house back together in readiness for my family and friends arriving for their holiday.
We weren’t there at the time but luckily for us our French neighbour took photographs of his preparation work. I have also taken photos of all the correctional work I’ve done and the garage hasn’t had any work done on it at all.
