Bathroom Fitting- 15 Nov 2017
Mario was an absolute gem from start to finish. After a leak left our only bathroom out of action Mario came in and managed the full project to perfection (and also had a great tiler and electrician who did some other works). Six months on and I cannot fault any of the works. Highly recommended.

Extensions- 25 Aug 2020
I did my due diligence on Vullcan, but things went downhill. After a week i got a pre-tax invoice for £3000 for a more "complex" drainage system which was already completed, this was the start of them trying to get around contract items and look for every way possible to charge extra fees which i can’t go through in the word limit here. When that dint work they refused to do the work. e.g. they literally installed a tempered glass sheet, with liquid glue on my roof and stated to me that this was a "roof window". I had to show them buildings regulations that this was unacceptable and illegal especially when our contract said it has to be a VELUX ROOF WINDOW! Promised a 6-8 week completion, this is 9 months later. I had now paid about 90% of the original bill and 100% of additional costs. The final payment was due after completion and a 2 week snagging period. But the demand for payments started, with threats to sue. This was laughable as they hadn't completed the job. •The roof was leaking •Electrical issues with the fuse box and multiple light /electrical points •Outstanding items •The buildings controls company stated they would not be able to sign off on the building work because of outstanding issues, which I wouldn’t have even known as they lied stating they HAD the certificate. I agreed to send a FULL payment to an escrow company and pay HALF of the costs so they can complete and fix safety issues but they refused! Shameful experience.

Extensions- 13 Jan 2019
George was excellent throughout - would highly recommend. Although I did not hire George to complete the whole job (as someone in my family is a bricklayer) he was instrumental in completing the build. A few points to demonstrate: - Fair and transparent quote (which was stuck to); - Flexible throughout delays caused by me (planning, etc.); - Supportive (advice on what he would do if he was running whole job); - Professional (including team). I will use him again.

Carpentry- 12 Mar 2025
Chris was great- he installed a internal bi-fold unit which needed some considerable adjustment due to the measurements of the space it needed to go in- he took his time to understand the problem and work out a solution- the doors now works great and often get complimented by those who visit. Chris then helped fit a number of doors with handles in the property upon request- doing a great job in the process. Chris is a very tidy worker and is very good at communicating and being punctual. He was always very polite and was very careful to make sure he took care of the space he was working in at the property. He is also extremely reasonably price- would recommend him to anyone else- and will for sure contact him if I have any other jobs doing. Chris is a star!

Insulation- 14 Feb 2023
I placed an add in mybuilder.com to have my house fully insulated and received many replies including one from Sergiu. After meeting him I felt he was the best placed person to carry out the work as he was the most knowledgeable and seemed to know all about the various types of insulation and which one I needed for my home. He fully explained the procedure from start to finish was always on time and tidied up at the end of each day.His work is second to none and the price was very very competitive in fact much less then the big companies were asking.I am extremely happy with the job and the standard of finish. Sergiu is very police professional and trustworthy and I would have no hesitation in recommending him to anyone on here to carry out work in your home.

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.
