Extensions- 3 Feb 2021
Gavin built me an outhouse at the bottom of the garden. The work was tidy and efficient and the result just what we agreed. This involved brickwork, carpentry and electrics, and all was done to a good standard and in a reasonable timeframe, even despite the snow! I would recommend Gavin to do this sort of work and would use him again if needed.

Kitchen Fitting- 3 Jun 2026
We recently used ANM Efficient Solutions for a range of renovation works, including installing and tiling our kitchen, laying a wood floor, and fitting both internal and external oak doors. Max and his team were professional, hardworking, and committed to delivering a high-quality finish throughout the project. As with any renovation, a few challenges arose along the way, but the team approached every issue positively and found effective solutions without cutting corners. What stood out most was their determination to see the job through properly. They didn't stop until all the work was completed to a high standard and we were completely happy with the result.

Extensions- 29 Nov 2023
We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

The refurbishment of my small one-bedroom flat took approximately 2.5 months. I compared several builders before starting the project. The price was not the cheapest and the proposed timeline was not the shortest. Though Radilina seemed to be a good project manager and liked that she works on a fixed price for each work.

Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

An incredibly positive experience from start to finish. I found Robbie and team were hard workers, very likeable and provided brilliant results. Comms throughout were excellent.

We understand the pressures this places on our tradespeople and we thank Robbie and his team for their diligence and commitment to wearing masks in our home and working safely.

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Tiling- 24 May 2026
I cannot recommend John from Pacho Create Ltd highly enough. I'm a very particular client with high standards, I was impressed by his care, patience, and professionalism throughout. He clearly takes pride in delivering quality work and paid close attention to every detail. Living in a small flat, I was concerned about dust, but John proactively created a solution to minimise disruption, which I really appreciated. He also gave excellent advice on budget-friendly waterproofing products. We had a challenge with large-format tiles, but John worked closely with me to plan the layout, ensuring a natural, balanced finish. The workmanship is outstanding – minimal wastage, precise alignment, and superb attention to detail. I wouldn’t hesitate to use John again, in fact, I’m already planning to have him back to tile around my bath in the near future. I highly recommend him to anyone looking for a skilled, reliable professional.

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.

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.
