Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Bricklaying- 23 Oct 2018
Tony and his team were phenomenal! Professional, courteous, reliable, tidy and quick. Tony's communication throughout the build was consistent, clear and precise. Tony really listened to me throughout the process; provided advice and options but most of all completed the project the way I needed it. The whole build went exceptionally smoothly, was finished ahead of schedule and on budget. Tony's workmanship is excellent and the final finish spot on. I was really worried about finding the right builder for my project... I simply could not have found better. I got several quotes from different providers and Tony's represented the best value for money. I highly recommend Lto builders, you will not be disappointed.

I asked Prohaus to undertake a ground floor side return and rear extension as part of the refurbishment of my flat in Putney. I have used many builders before on development projects but was especially impressed with Naz and his team on this build. It was the first time I used them and won’t be the last. Naz was great to work with, the whole build went smoothly and he always had a positive attitude and solution to any unexpected issue. The build came in on time and budget which was very impressive in itself. All in all I would highly recommend him.

AT Line Construction built our extension and worked on the remodel of the inside of our flat. We are extremely happy with the results. Adison and his team are very professional and friendly. They were able to deal with any changes and problems that came up quickly and sensitively. Part of the build was to renovate a small disused swimming pool - this was a tricky job, and they were able to help us creat an amazing pool. We would definitely recommend them.

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.
