Spoke to Mark short time after the job was posted and he called to appraise the situation that evening. He was friendly and polite and knew immediately what the problem was, which is where experience cones in to its own. He explained what had happened and how to rectify it and how much it would cost. I had complete faith in him and hired him to come back this morning. Despite the inclement weather he arrived cheerful and on time, and together with his assistant had completed the repairs quickly and to a high standard. I will certainly use Mark again and have no hesitation in recommending him to other people who want a timely, professional and reasonably priced job done. I have used My Builder.com a number of times and they have never let me down with the calibre of tradesmen they represent. Thank you Mark, Thank you My Builder!
