Hello to all visitors to my profile. My name is Przemek, I deal with interior renovation, bathroom finishing and kitchen installation. I owe this to my acquired experience. I have been working in UK for 7 years, of which for 1.5 years I was a bathroom and kitchen fitter at the "WICKES" store. I am a precise and aesthetic person. I love order at the workplace and I like seeing a smile on a customer's face.

My colleague referred me to Raed who previously have had used R.Hamandi Ltd for construction work and they were very happy with the quality of service. Along with some other building company's last year I also contacted Raed for an estimate. Raed gave us a reasonable price with all the details of proposed work. He also explained about the possible options of how we could get the best value for our money. His professional and friendly advice helped us a lot to understand what exactly we needed and what was best for us to go ahead for our project. We decided to go ahead with R.Hamandi ltd. Raed gave us breakdown of the project and everything was documented. His support in communicating with council and planning related issues was valuable. All the planning permission requirements were followed. Presence of experienced and trust worthy staff including laborers, handymen, carpenters and painters really made it easy for me and family to be around and comfortable while they were working or to leave the house whenever we had to. Raed himself used to visit the site everyday to oversee the progress and used to discuss and take care of any possible issues. Raed's team used to turn up on time and the project was finished on time too. Even after the completion of the project staff at R.Hamandi ltd and Raed himself contacted us few times to find out if we're happy with the work carried out or if we needed any further assistance. Now we have a fully refurbed house with double side extension and loft conversion. Overall amazing service, professional, reliable and trustworthy. I recommend R.Hamandi ltd to everyone for an A+ service. Thanks,

Extensions- 11 Oct 2023
We recently completed an extension at the rear of our property, along with a kitchen renovation and refurbishment of our reception hall. Abdallah and Hesham were instrumental in this project, providing us with a comprehensive work plan. Their labor costs were exceptionally reasonable, and they demonstrated unwavering dedication to the job. Their hard work was evident throughout the project, not only in the construction but also in coordinating plumbing, electrical work, and kitchen fitting through their skilled team. Abdallah co-ordinated well with building regulations, ensuring that our project complied with all the necessary standards. What truly stood out was their flexibility and willingness to adapt to changes and adjustments, especially when dealing with variations in material sizes. This adaptability greatly facilitated the project's progress and success. Thank you Abdallah and Hesham.
