    Hi, I’m a skilled and reliable multi-trade construction specialist with several years of hands-on experience across a wide range of domestic building work. I originally started as a handyman and have since developed a strong all-round skill set through practical on-site experience. My main areas of work include kitchen fitting, bathroom installations (including toilets, showers and fittings), tiling, flooring, media walls, patios, and painting & decorating. I also have experience in general building and repair work, which allows me to take on a variety of projects from start to finish. I hold qualifications in bricklaying and plumbing from City & Guilds, which support the practical experience I’ve gained working on real projects. This combination allows me to deliver work that is both structurally sound and finished to a high standard. I take pride in being punctual, tidy, and easy to communicate with. I understand how important it is for customers to feel confident in who they hire, so I always aim to be clear with pricing, honest about timelines, and committed to delivering quality results. As I’m currently building my profile on MyBuilder, I’m focused on providing excellent workmanship and earning strong customer feedback.
