From the initial meeting to the completion of the job both Sam and josh were fantastic, punctual, polite and more than happy to discuss any issues. The work was completed to a very high standard and I would have no hesitation in recommending them. I have already asked them to do another job for me and certainly will in the future.

Extensions- 12 Jan 2019
Wow, wow wow. I do not even know where to begin with this absolute gem we managed to find local to my father in laws project in Southminster, Essex. My in-law is not the easiest guy to work with but John worked so hard to fix all the previous issues a cowboy builder had left him with and he also worked very hard day and night (sometimes 15 hours!!!!) He went above and beyond service. We have never seen such perfect plastering (like glass) and structurally sound work being done by a true professional. He also finished the extension with cladding on the outside and flooring in a huge 80sqm space and to say we are all extremely happy would be an understatement. If you're wondering whether to hire John, please do not! He is worth every penny, he is reasonable and wants to do the job to please you and likes to finish to a very high spec and is always on time and reliable and gives you great ideas to make the house look perfect. Without a doubt the BEST builder we have ever hired and we cannot wait to use John again and again in the future. Thoroughly recommend and wouldn't hesitate to reference any of Johns future work. Thank you so much John, thank you!!

Kitchen Fitting- 18 Nov 2025
Original timeline stretched a bit due to his other jobs but this was fine. Mario started work early and finished early which suited us. He came to visit and we agreed a price at the start and he stuck to it even when he realised some additional plumbing would be needed. He was honest about some accidental damage. Attention to detail is good and he has all the kit. I would have given 5 stars- he's a proper professional and I enjoyed working with him. 3 stars only because as soon as the work was done he became incommunicado (I messaged a week later to ask how to lift door which had dropped down a few mm on fridge). The warranty advertised is one of the reasons I went with MGB which was £200 more expensive than contenders so this was disappointing. I would have asked him to do my parents' new kitchen too otherwise.

What to ask a Tonbridge extension builder before hiring?

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

An extension builder in Tonbridge 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 Tonbridge 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 Tonbridge?

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 Tonbridge 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 Tonbridge 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.
