Extensions- 24 Jan 2021
We chose Gibbons and Sons for our Loft extension and new bathroom as they was one of the few firms who we contacted and was more then happy for us to view their workmanship during and after the build so we good see the quality of their works. They have been courteous, polite, very patient and accommodating to our chopping and changing of ideas. They helped us to bring our visions to life and offered advice when required without being pushy and driving a hard sale. They have been open and honest with our ideas and their recommendations and in some cases suggested a alternative more cost effective option. All in all we would highly recommend Gibbons and Sons for all types of building works.

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.

What experience do you have with similar extensions in Highbury?

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