Have had a poor experience. Communication not great. Had to complain twice. Sent an email last week asking for job to be finished. This and subsequent email has been ignored. They did not come on the day they said and when they came later they couldn’t access the pipes to finish the job. The engineer said he would come back the following week but no one is responding to emails. It’s a shame as much of their work is good but I don’t think they understand how complicated the project is and that they need to be clearer about what is required and stick to their deadlines. If things change they need to explain what access they need and not rely on the small print of an email sent 6 weeks previously. Just because they do this all the time doesn’t mean customers know or can remember every detail.
