Extensions- 17 Nov 2025
Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

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.

What to ask a Bow extension builder before hiring?

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

An extension builder in Bow 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 Bow 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 Bow?

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 Bow 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 Bow 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.
