We are delighted with Tim’s excellent and professional service in fitting a replacement radiator and clearing a problem drain for my elderly mum. He responded straight away with his quote and I found him very reassuring when he explained on the phone how he would carry out the job and how he was able to complete the job within a week, which was perfect timing for us. He was friendly, efficient and completed the job to a high standard. We are very happy and would thoroughly recommend without hesitation.

Harry and Mark were absolutely brilliant. Harry's communication was excellent and he went above and beyond on my bathroom and full flat renovation. He made helpful suggestions, managed parts of the project, sourced a new boiler at a great price, and brought in a fantastic team. I trusted him fully, even giving him a spare key. I felt genuinely prioritised and supported throughout. Would highly recommend.

I have no issue with the work they did, but they should routinely carry cleaning equipment such as brooms, dustpan and brush and a vacuum cleaner. They should not need to use mine, or ask me for a bucket to mix up plaster in. Finally they really should take their rubbish away or tell their clients the price does not include rubbish removal. Putting it in my neighbour’s bin and on my garden is unacceptable.
