Groundwork & Foundations- 7 Nov 2024
From start to finish, Bogdan and his team were exceptional. After dealing with a previous builder who caused numerous delays, I found SBG Services. Bogdan came by the same day to assess the job and impressed me with his extensive knowledge. Given my tight schedule, he got to work immediately. I’ve never seen a builder work as hard as his team; they labored tirelessly from morning to night to ensure the project was completed promptly without compromising quality. Every trade I've had since has commented on their attention to detail. In just three weeks, they completed two extensions and transformed my garden. I will definitely be calling Bogdan back to handle my front garden early next spring.

Extensions- 19 Jun 2016
Neno is a very warm-hearted and genuine person. He gives his 100% to the job. He is also very prompt when it comes to communication and is always available by phone/text/email. He has a vast experience and good technical know-how and produced excellent plans and drawings. His quotes were very reasonable and offer excellent value for your hard earned money. Having been his client, I am genuinely inclined to believe he is a person who would never "rip off" his clients. He is a man of his word and does what he says. However, Neno's honesty and confidence can be a bit blunt at times. He can be quite “direct” with his opinions and this may rub off some people the wrong way, e.g. your local Council Planning officer may be an a**hole, but if you "confront" him, he will definitely not make things any easier for you- nevertheless, Neno dealt with all the Council red tape and followed up the Planning Permission Application to its conclusion. We finally got permission for extending the property much less than what we had expected initially- apparently our local Council (Hillingdon) has its own set of Draconian conservative rules that we were unaware of- but we have postponed the actual project work due to a recent change in personal circumstances. Summary: Based on my personal experience, I would DEFINITELY RECOMMEND Neno as a bona fide Tradesman on MyBuilder.com.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

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,
