We have been working with Derek Borkiewicz (Sebek Construction) on a renovation of a garden flat in Little Venice since last autumn. We needed to completely restore the whole flat, including the garden. This was our second renovation project and by this time we knew what we wanted to do, which mistakes to avoid and what to pretend from a qualified builder. We will never stop saying how lucky we have been to find Derek and his team! Derek is not only a professional builder who is very careful to the smallest of the details. He is not only a very good project manager who is constantly checking the work of his men. Derek is a friend who takes on board a project like it is his own project. He suggested the most convenient and best solutions for any problem we came across during the works. There wasn’t a time when he didn’t know what to do to solve a difficult situation (and there are lots of small and big issues coming up in a renovation work) no matter how complicate they were and how long it took to solve them. His availability and his courtesy are incredible above all in a fast running city like London. This is priceless to us. His hard work can be seen in the wonderful result we reached with this garden flat. If we ever decide to work on another project we won’t think twice about working with Derek once again. In fact, now that we found the perfect man to work with, we are looking forward to finding another renovation project to work on! Monica

Extensions- 14 May 2025
Jon was able to take a failed project from a previous contractor and manage historic building preservation, regulation in Westminster, a lack of parking, plumbing from the Victorian age, and a demanding client to deliver a beautiful result. I love my garden flat extension, it manages to respect the historic nature of a building from the 1840s while also adding amenities to be proud of in 2025. Thank you Jon (and team) and best of luck with future business.

What to ask a Wimbledon extension builder before hiring?

Before hiring an extension builder in Wimbledon or extension building company in Wimbledon, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Wimbledon 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 Wimbledon 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 Wimbledon?

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 Wimbledon 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 Wimbledon 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.
