Joinery & Cabinet Making- 28 Oct 2022
Rafal was very helpful, and came up with alternative solutions to the job too from what I'd first suggested. He was prompt, cleaned up each day, and did a really good job which I'm very happy with. It was slightly worrying not to get a confirmed price for the work beforehand, just an estimate, but it turned out that was because it was hard to tell the time the job would take, and in the end what he did charge produced a really good result. I'd highly recommend him.

Extensions- 21 Sep 2019
Ray has done an outstanding job with the new extension. He has shown great attention to detail and accommodated every request. The result is one that we are extremely happy with. He installed a new bathroom downstairs complete with all necessary pipework and a new utility closet with exits for the washing and dryer. Clearly Ray has a very broad set of skills, from electricity to building to carpentry, plumbing and roofing. He really was the one stop shop to make this extension a reality and has a network of people he can call onto if required. He is certainly someone that takes pride in his work and wants a job well done as evidenced by his work. I recommend Ray without a doubt and I'm sure our paths will cross again. Thank you Ray!

Extension Builder in Hemel Hempstead
I started in the trade at 17 labouring on my father on his building sites and learning from many skilled trades. I’ve worked for a few local builders since but 5 years ago went out with my father again and we have been doing so ever since. For the last 3 years we have been working mainly in north London. Have recently started taking on local work again as well due to demand for skilled and reliable trades locally.

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,
Marin
