Restoration & Refurbishment- 25 Jun 2026
Ziggy has just done a huge piece of work for us over the past few months, decorating and refitting our kitchen, relocating a doorway, taking out a chimney breast, fitting a media wall, resizing and replacing windows and rendering our rear wall. Everything has been done to an outstanding standard. Ziggy takes great pride in his work and his reputation and is a real perfectionist. He’s communicated well all the way through and managed any anxieties we’ve had about such a big piece of work. He’s also provided advice when we’ve needed it. Ziggy’s really upfront about costs with no unexpected shocks. Ziggy was often supported by Darek. Both were always really respectful in our home. We needed someone we could trust and couldn’t be happier. We have future projects lined up and have no doubt we will use Ziggy again.

Our driveway spotlight sensor stopped working - replacement spotlights, new stronger cable fitted, replacement driveway wall mount lights, disability ramp made and driveway washed. pretty straight forward. Sam bought the correct lights, extended cable and the sensor with his electrician from B&Q. Removed and replaced removed all the rubbish, respected our property gave the driveway a wash no hassle - left them to do their work and it was done. I would recommend using them they do what you want and how you want it - He does give you his opinion though up to you if you want to take it or not. happy to use them for further jobs

Joinery & Cabinet Making- 6 Aug 2022
Chris did an excellent job of designing and building a high quality radiator cover around our bay window. It was a tight space with lots of wonky walls so not a straightforward job. Chirs asked lots of questions to get the design just right and made good recommendations. I was very impressed with Chris' communication throughout the job and would certainly use again. Thanks again.

Extensions- 11 Nov 2024
Really positive experience working with Jamie and his team. Our building project was a single story 3m x 5m kitchen/living extension for a 1920’s London terrace house, with access to the garden only available through the house. From the start during the initial home visit survey and quotation, Jamie was 1) excellent at communicating; 2) transparent about costs and 3) proposing very good options (e.g. 2m x 1m skylight) which looks fantastic! The job included digging foundations by hand and very good awareness of the extra precautions when doing work in an old period property. The job was completed on schedule and on our budget and we are very pleased with the finished extension. 100% would recommend for anyone looking for similar type of project. Cheers.

What experience do you have with similar extensions in Bexley?

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