Bricklaying- 11 Mar 2023
The builder came to build a single skim brick wall to the side entrance of my house -: around 120 bricks. He agreed to £300 for labour including inserting a door. Upon arrival, of which he came on foot, he had no tools, no bucket, no drill, no ladder. He had to borrow all of my husbands equipment and sent my husband out for extra materials on two occassions. The lintel he asked us to order was the wrong size, we ordered one that was far too big and wasted more money due to him measuring up the job wrong - again a waste of money. Then, we had to drive him to toolstation to buy a brick cutting tool because of this using our own time and fuel. You would assume a brick layer would have tools if they are doing jobs privately - his colleagues excuse was we are just starting up our private buisness. He then started asking for more money and stormed off leaving all the rubbish behind even though we gave him the £300 as agreed prior to the job. The wall itself is okay but again at one point he refused to build up to the top because of a metal screw apparently impossible to remove, so yet again my husband had to assist with the job and removed the screw. Honestly more hassle than it was worth. Also the door was not fitted so now will need to pay someone else to do the job. I do feel bad for them that do not have any equipment but when you pay money for a job you do expect a certain level of service. I wish them good luck in the future and hope they take this advise on board.

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- 3 Oct 2025
Job was to convert WC in outbuilding into a full bathroom, do walls and ceiling in outbuilding to convert into an office space. Price was agreed with things planned, still with some issues towards later part of job, It worked out in the end. Overall I am giving 3-4 stars as quality of work is good. Just need to have things written down with him, and a thorough discussion on plan before commencing work and agree on payment plan. suggested to keep 20% to be paid at completion.

What to ask a Blackwater extension builder before hiring?

Before hiring an extension builder in Blackwater or extension building company in Blackwater, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Blackwater 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.

Will my home extension meet all building regulations and planning requirements?

Your Blackwater extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Blackwater?

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 Blackwater extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Blackwater extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
