Conversions - General- 3 Apr 2025
We recently had extensive building work carried out in our kitchen, including alterations to a window and door opening, fitting new doors, installing a new kitchen, and completing decoration works. From start to finish, the experience was excellent. The quote provided was exceptionally detailed, outlining the full scope of work, a clear timeframe, and a draft contract. It was also very competitive compared to other quotes we received. The work was completed even quicker than expected, thanks to Pawel, the highly organised team leader. He and his team worked incredibly hard, ensuring we were involved throughout the process to accommodate all our needs. Their attention to detail and professionalism were outstanding. The final result has exceeded our expectations – the kitchen looks amazing! We highly recommend Pawel and his team for their expertise, efficiency, and dedication to delivering high-quality work.

Extensions- 13 Oct 2023
Sagar and Sanjeev are incredible- they are very diligent and really well versed in what they do! They know what they are talking about and are very friendly and incredible to work with. There was no issue that they weren’t able to help me through when it came to a complete renovation, extension and garden landscaping of my house. They are experts in what they do and they’re the only contractors I want to work with for any other works in the future. Would always recommend them. 100/100!

What to ask a Surbiton extension builder before hiring?

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

An extension builder in Surbiton 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?

What experience do you have with similar extensions in Surbiton?

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