Happy Client · London
Radiator Thermostat Valve Installation
"I had 2 showers - one that was running too hot and one that was running too cold. Theo explained what the issues could be on the phone and it was agreed that new showers would be needed. He ordered them straight away and came out the next day to sort it. He was really friendly, explained the issues clearly and was tidy. Would highly recommend!"
Repeat Customer · London
Bathroom & Kitchen Plumbing
"Theo sounded scary when I first spoke to him. But I couldn't be more wrong. Hes a gentleman, professional, friendly and reliable. I am very happy with the advice he gave and the pump installation. You can see he takes pride in his work as he is just as restless as you until the job is done and looks good."
