Kitchen Fitting- 1 Jan 2023
I have to say that Tyrone who carried the work out for is very professional and commendable. He was always on time and eager to get the work done. His attention to detail is simply quite impressive. Having completed the work i was rather surprised to learn that he called back the next day only to complete a very small detail that he forgot. A small detail that was not exactly noticeable, thus leaving us with satisfactory results. I’m certainly going to recommend their services to anyone who might require their services. Many thanks 👏👏👍

Extensions- 7 Apr 2025
Quotes were provided and the job was agreed upon. The project involved a full house restructuring and extension build. However, after several stages of work, communication with Jas was lost, and his co-worker took the lead on site. Several issues arose, such as recommending smart plumbing equipment for purchase, but their plumbers were unable to install it. The tiling, skirtings, and tiles were not completed. Tiles around the columns were cracked. After Jas's team abandoned the project, another plumber had to install all the remaining items. The job was left unfinished, and we had to find alternative contractors to complete it. Significant time and money were wasted due to persistent communication problems, failure to issue invoices, and numerous other issues. Eventually, Jas and his main labourer stopped responding and disappeared, ignoring phone calls and WhatsApp messages. Be aware of these potential issues.

Bricklaying- 6 Jun 2026
Absolutely fantastic service from start to finish! The team demolished our fallen garage and built a brand-new one to an excellent standard. Communication was brilliant throughout the entire process, keeping us informed every step of the way, and the turnaround time was much quicker than we expected. Everyone we dealt with was friendly, professional, and always happy to answer any questions. The workmanship is outstanding, and we're extremely pleased with the finished result. I wouldn't hesitate to recommend them to anyone looking for a reliable and professional company. A big thank you to Teresa, Jason and the team. Thank you for a job well done!

What to ask a Blackwall extension builder before hiring?

Before hiring an extension builder in Blackwall or extension building company in Blackwall, 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 Blackwall?

An extension builder in Blackwall 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 Blackwall 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 Blackwall?

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