Florin fitted my new bathroom and kitchen . He was very polite, always punctual and reliable and completed the work to a high standard. I would use his services again and recommend him for installation of bathrooms and kitchens.

The service was excellent. Artur came the day after I posted the job (the Friday), and true to his word, he and his team started the job on the Monday. The work was of excellent quality. They worked very cleanly, even going beyond the point of duty, moving articles out of the way. The work was completed within a week as promised and was of exceptional quality. I would not hesitate to recommend to anyone for painting, decorating and building work. Well done.
