Carpentry- 4 Jun 2026
I recently had Alex install my 12-foot pegola, and I couldn't be happier with the result. From start to finish, Alex was patient, listened carefully to what I wanted, and took the time to ensure everything was done properly. He is hardworking, reliable, respectful, and kept the work area tidy throughout the project. What impressed me most was how efficiently he worked without compromising on quality. The pegola was completed to a very satisfactory standard, and the finished result looks fantastic. I would have no hesitation in recommending Alex to anyone looking for a skilled and trustworthy tradesperson. I would gladly use his services again for future projects.

Bathroom Fitting- 9 Feb 2019
Alexandros did an exceptional job with our bathroom. As it was our first major renovation we were very anxious about the whole process but Alexandros made everything very easy and smooth from the beginning until the end. Alexandros has a lot of experience and he is full of ideas and good suggestions. The new bathroom looks amazing and we could not have chosen better than Alexandros. Alexandros was very helpful throughout the whole process. I would highly recommend Alexandros to anyone and we will definitely use his services in the future.

Plastering- 5 Aug 2019
The job was more than a standard plaster job it was a complete refurbishment of the dining room with the new flooring extending into the hallway. Ionut did an amazing job his attention to detail is first rate I have used quite a few builders over the years and I can honestly say Ionut impressed me the most. He is hardworking, meticulous to detail, tidy and goes above and beyond the job that has been agreed. An example of this was him deciding to hide all loose wiring while he was doing the skirting which has made things much more tidy and also doing new flooring and skirting under the stairs without me asking. He wrapped everything in plastic during the job (radiators, doors, light sockets etc) no plasterer I have used before took that much care in protecting things during plastering which as we know is a very messy job. We will be recommending to all our friends and in the future he will be the first contact if we need any more building work. 100 percent recommend his services and thank you Ionut for the job you have done for us

Carpentry- 27 Mar 2026
The job was executed to the highest standards. Tzouliano was clearly very knowledgable and experienced. He explained what work needed to be done, what he would do and was very honest about what was possible and how durable it would be. He was also very polite and respectful (he took his shoes off every time he walked around the flat without needing to be asked). I would definitely recommend him for any carpentry job.
