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.

Behrooz was hired to install underfloor insulation for soundproofing and engineered wood flooring in our flat. He was always on time and let us know when his working days and hours in advance. During the process, additional works arose as it's a Victorian house, which Behrooz explained in detail. We proceeded after discussion. We were on a tight deadline, but Behrooz and the team made it happen, even willing to work later hours, which I appreciate. Highly recommend!

Nicolae was punctual, knowledgable and tidy! He tried to identify a leak (turns out the problem may be the washing machine rather than a problem with pipes). He helped rectify the washing machine. He tidied up after himself. Cannot fault him. I have already asked him to return to do other works in my home.

I recently had Luke and his team widen an opening between two rooms in my property, which was a sizeable job requiring the installation of a steel beam. The work was managed efficiently, and great care was taken throughout the project. I’m very pleased with the results and would highly recommend Luke and his team for their professionalism and attention to detail.
