Latest review:
I engaged Edi to work on a full renovation and refurbishment of a 4 bedroom detached house with front and back gardens on Blackheath’s Cator Estate. Edi did an extensive amount of work, including stripping out; plumbing; plastering; windows installation; carpentry; and decoration. In addition, after commencing the property work, once the scaffold had been erected, following sensible advice, Edi and his team replaced the roof and fully insulated the attic; fitted additional electric points; rebuilt the garden patio; and replaced the flooring throughout, in addition to other important jobs including re rendering and pointing of chimneys, building new wardrobes in the main bedrooms; and upgrading the radiators. A new kitchen, and two new bathrooms have been fitted. The kitchen redesign meant knocking through a wall with the lounge to create a larger space. Edi is a highly skilled craftsman, who thinks creatively as he works to make best use of the space, including shelf fittings, and additional lighting for example. He has built some beautiful wardrobes, and the internal decorations have brightened up what was previously a rather shabby looking house. In addition to the above, I wish to commend Edi for his professionalism, courtesy, and passion for doing the best work possible. On all the site visits I attended, and every time I spoke with him on the phone, it was striking how much he cared about the work that he was doing, his desire to ensure that the house would look the best. I always left site visits with the feeling that he cared so much about the house that he could be safely relied on to give the best advice to enable us to make the right decisions. I also noticed that Edi and his team would take the upmost care to keep the property safe, tidy and in good shape throughout the project. He can be fully trusted to look after any site he works on. He is intelligent and careful when it comes to safety and security. It has been a pleasure for Edi and his team to work with us over a period of around 6 months, and he did so much to reduce the stress of a significant project so that we could always rely on him to work methodically, patiently and sensibly, and to make best use of the resources available. His pleasantness shines through, and everyone I know who has spoken to him has always provided me with the most positive feedback I have no hesitation in recommending Edi to anyone who wishes to engage him for future projects, and is most deserving of the good words that I and others that work with him have to say about him.

Extensions- 9 Apr 2017
Overall a good job. They got a very good match with the new bricks on the porch to our existing house and the porch looks good. The job did take slightly longer to complete than we had been told and there are a few small things that could have had a better finish, but then we haven't asked Bauer to put these right so can't fault them for what they don't know. Overall we would hire again and we are pleased with the result and value for money.

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

Extensions- 23 Feb 2024
I’m literally blown away by this team of guys. Professional from start to finish. Danny quoted promptly in the timeframe he promised after he viewed the project. He was clear about what he could deliver with the budget that I had and made suggestions using his knowledge that helped me achieve the dream garden room that I have always wanted. His team turned up at 8am sharp and work started at 8.01 every morning. It’s clear that Danny surrounds himself with professionals that he can trust to execute his promise and deliver the quality he expects, and that his clients pay for. Another plus is that he was extremely accommodating to some changes that I asked of him during the build which he also didn’t charge for. Nothing was an issue to this man and he clearly operates a “client first” attitude which was apparent also when he visited every second day to check progress and quality. Lastly which is also something that I didn’t expect is that he had the extra materials that were not used collected and credited to the final bill. If I had more time I could go on all evening but my final words are. Look no further. With Danny you have found an honest professional business man that takes pride in his work and I am happy that I found him and his team. Good luck with your project.

Plumbing- 24 Jan 2026
I did hire Aiden De Winter for the job. He came and inspected the problem and sent us a link to purchase a new pump. I paid him for this work. We purchased a new pump, and he decided not to finish the job and come back to install the pump. This caused a lot of problems as he was the second plumber I hired for this job, and now we have to find a third plumber! What a waste.. how hard is it to come back and fit the pump! Do not use this company at all costs!

What experience do you have with similar extensions in Caterham?

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