Denis did a fantastic job. He arrived on time, he is very knowledgeable and knows his craft, worked outside in the cold and finished the job efficiently. We are so pleased with his work, railing looks good and even the neighbour was impressed and said how nice it looks. We will definitely ask Denis again for any future building works and I would not hesitate to recommend him too.
