CAD / Drawings- 23 Sep 2020
Marius has been doing a great job and put in an extra effort to ensure we were happy with the outcome. I can not recommend Marius highly enough, especially as he managed to fix an issue with the council that we had from someone else drawings. He was patient and very well prepared. Went an extra mile and gave us different ideas/options. He was flexible with timings and most importantly with price. Had by far the best quote and did an exceptional job.

Kitchen Fitting- 25 Jun 2026
It was a pleasure to deal with Florin. He came quickly to give a competitive quote. He then did the work in a professional and friendly manner. He is assiduous in his preparation, checking some tricky measurements at least a couple of times before starting. He kept me informed of progress and checked in to ensure I was happy with the job. He turns up when he says he will and works hard to make sure things go to timeframe.

Landscaping- 3 Jun 2021
On our first meeting I felt comfortable and was glad of input from Robin. Agreed to a plan and only had to wait a few weeks before work could start. All preparations made to protect my drive before skip arrived. All work carried out in a very professional manner and team were very polite and friendly. Even though weather was against ground works they provided shelter so work could continue. I’ve been very pleased with their approach and can’t fault the outcome. Although met with a couple of delays on garden furniture, (nothing to do with Robin and his team, circumstances outside control)all other aspects of this job have met with my approval. Was apprehensive of having people in but can honestly say there have not been any issues and when the skip was removed within an hour, Robin was back on site to clear and wash down the drive. So looking as good as new. It’s been a pleasure having them on my property and will look at using their services again in the future should the need arise. Nothing too much bother. So my thanks to them all.

I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

What experience do you have with similar extensions in Mitcham?

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