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.

Did a fabulous job on my back yard concrete patio which was crumbling in places and needed levelling. Also suggested adding another step to a rather steep step in place already which made perfect sense and he did a great job with that too. Took 1 day and sent photos of the site after work. Very impressed and very happy with the outcome. I recommend this company and will be using them again on other jobs in the future.
