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,

Chris hung a number of prefabricated doors and door frames that needed adjusting. He promptly provided us with a detailed quote and his availability. He did a job on a Saturday which was great as we really need this job to be done as soon as possible. The job was completed quickly, the adjustment to the doors are practically not noticeable and the doors and frames look great. Chris and his helper were very helpful and did a great job for us. Will definitely us Chris's services again.

Architecture- 17 Sep 2025
Overall we are happy with the work that has been done, however the whole experience has been soured by the fact that I am still chasing to have the new hot water cylinder properly commissioned almost 2 years after installation meaning I cannot have it serviced and won't be able to claim on the warranty if things go wrong. My home insurance will also not pay out on any damage that may be caused. The other issue is that the two consumer units that were installed have not been labelled so I have no idea which breaker does what, this is a safety concern. My many attempts to contact Mandeep about this have been fruitless, I'm just being ignored.

What qualifications and experience do you have as an extension builder in Sidcup?

An extension builder in Sidcup should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

What experience do you have with similar extensions in Sidcup?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Sidcup extension builder’s ability to deliver a result that meets your expectations.
