Delighted with the work carried out by Matt and Mike at Modest Property Services. They were punctual, reliable, friendly and tidy throughout the time spent removing old bathroom suite and installing my new shower room. From initial planning stage to completion there was excellent communication, with Matt consulting me at all stages to ensure things were as planned and expected. I would definitely recommend these guys to anybody planning a bathroom project. Love my new shower room!! Thanks both 👍
