My husband accepted and paid your bill at the time it is only subsequently that we have found out from others that this was an excessive amount to be charged for this work.

Latest homeowner review

Reviewed by Hugh on 7/5/2025

The previous review was done under duress with Billy standing over me. The truth is, he disappears for considerable lengths of time (days), leaves equipment behind so you can't hire anyone else, switches his phone off so you can't contact him during this time and has the attitude of a bully. He removed our toilet to fix a blocked pipe but then left it so it wasn't fixed back to the floor properly and moved around, when we were in the process of selling our flat, with surveyors coming round. Not recommended.
