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.

I provide reliable property maintenance and repair services with a strong focus on quality, problem-solving and attention to detail. I’m best suited for clients who value a proper, long-term fix rather than quick temporary solutions. My work is organised, tidy and carried out to a high standard. I have experience across a range of residential jobs and consistently receive positive feedback for communication, reliability and workmanship.

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.
