I’m Noli Antzara, a North London tradesman with 37 years of experience. I started working alongside my father at 18 and have spent my working life developing my craft. My main specialities are tiling, paving and brickwork. I also take on bathroom and kitchen tiling, slabs, garden work, blockwork, extensions and painting. Whether it’s a small repair or a larger project, I give the same care and attention to the finish. I prefer to visit the property, listen to what you want and provide a clear quote before starting. Depending on availability, I can often begin within one or two days. I’m based in North London and can travel approximately 60–70 miles for the right job. I know that inviting a tradesman into your home takes trust. I treat every property with respect, protect the areas I’m working in and keep the space as tidy as the job allows. I communicate clearly, take pride in the details and want you to feel comfortable raising questions along the way. After 37 years, I still care about improving and doing work I’m proud to put my name to. My aim is simple: to deliver a quality finish and leave every customer feeling that their home was in good hands.
