Handyman- 12 Oct 2018
The flat was left in a very bad state after the tenants left. Marius was able to undertake all the jobs, from changing carpets, redecorate, repairs and clean up. Also gave good advice as I was not able to attend the site in person so Marius kept me updated with photos. The price was also good. Thank you. Will use these guys again.

Extensions- 22 Apr 2019
Richard and his team have always been very hard working, respectful and professional throughout the project. We have had an extension, utility and bathroom/toilet renovation and we are very happy with the quality of work. It has transformed our home into a beautiful living space. Richard was very helpful when giving advice on materials we were choosing. The team were very accommodating to our needs, easy to work with and always tidied up after themselves. The payment schedule made it easy to keep on top of the budget and pay for any optional extras along the way. The building work was completed within the set timescale and to a high standard. We would highly recommend Lux for any building/renovation work.

We hired this builder for a 2-metre rear extension and a very large garage extension and we’re really happy with the result. The project needed a pile foundation which is a bit more complicated, but they handled everything very professionally. They listened to what we wanted and kept us informed at every stage, which really helped as we were living in the house while the work was being done. The team were friendly, easy to deal with and worked to a good standard. Overall a very good experience and we would happily recommend them.

Painting & Decorating- 6 Oct 2022
Very pleased with our choice. We initially got four quotes from different builders, most of them were terrible at communicating apart from Alfred. He was very easy to work with, responsive and very careful with our brand new house. His team was hard working, tidy and fast. They completely renovated our garden from removal of old decking and gravel to setting up new fences, levelling and turfing the ground. They also removed our old kitchen, partition wall and carpet, as well as did jobs like plastering, building a wall and set up lights and shelves. We’ll surely have him back soon to work on other jobs.

Would highly recomend Tony and his team, clearly know what they are doing and have done and seen it all before! We had a rear and side extension, Tony kept us well informed throughout the job what the next stages will be etc, was always on hand during all stages every day, even weekends when needed, nothing slowed the job down and we were done in great time! Nothing was not possible, even down to me being fussy with a wall, its beyond my expectations! Thank you and your team Tony 😊

Extensions- 5 Sep 2019
The builders did an incredible job refurbishing my house. For my house I wanted to break the internal wall to create a bigger living room and also for them to refurbish the toilet. In the beginning they’ve set a period when everything will be done and they’ve stuck to it so they are trustworthy. Seeing the progress, I could definitely tell that they were working incredibly hard and I know that they have been working long hours to ensure that they manage to finish it within the timeframe that they’ve set. I would definitely recommend them.

Extensions- 11 May 2016
Really happy with the work Paul and his team did on our extension. They were quick, neat and tidy throughout and kept us updated at each stage. There were some early design changes which building control insisted on and they were happy to adapt to the new plans without fuss. We couldn't believe how quickly it was all finished and the standard of work was very high too. Would definitely hire again if we ever need to.

Great company. Came round on a Sunday to look at the job and quote and were so totally honest, they told us they didn't think anything was required! They left a quote if we wanted them to take up the floor and explore further what we thought the issue was but said, in their opinion, nothing was required. How refreshingly honest. Great guys, great experience, thank you so much

What experience do you have with similar extensions in Charlton?

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

How long will the extension take to complete?
