Carpentry- 10 Aug 2023
you will see I ask for experts in my job posting because my desired outcome of this job was quiet floor as you walk across. I hired LTDinchev and the 2 gentlemen were helpful, pleasant and friendly. The job was completed for the price quoted and in the time specified. my only disappointment is after the job was completed I still had SOME of the same floor noises. so although they work hard on my subfloor I did not get 100% my desired outcome.

Bathroom Fitting- 28 May 2025
I am extremely happy with the job Isac has done. We are so very lucky to have found Isac to do our home. At the time of the works we were expecting a baby and Isac worked night and day to make sure our home was ready in time for our sons arrival. Without him we would have been screwed. Isac’s work is extremely professional. He has high standards and is very skilled. He’s honest, direct and respectful. I now consider Isac as a friend. He’s come back a few times since the works to check in and is always on the phone is you have any follow up queries. I would recommend Isac to anyone who has work they needed done. Thank you Isac!!!

Bathroom Fitting- 2 Jan 2025
Extremely Disappinted with Planetium Construction- I hired Planetium for a 59k renovation job. Initially, the workmanship was acceptable only because I supervised closely and had them redo substandard work multiple times. However, before the job has been complete, I discovered already a roof leak in the master bedroom, direcly under the newly renovated bathroom. Despite my repeated requests, Planetium refused to take responsiblity or fix the issue. Just telling me need additional charges for the work. Worst still, Adrian the owner, demanded I pay the final balance of 1840 before they would address the GF heating which stopped working after they installed the new controller. When I reasonably refused to pay before they complete the job , Adrian swore at me over the phone the most offensive language. Furthermore, they promised to replace a new Miele microwave for the one they damaged during installation but now just walked away. Leaving me unresolved issues and additional repair cost!

Plumbing- 21 Sep 2025
The initial quotation for work was to fit a kitchen pipework for an island, however we decided to use Nil Building Company for our new home renovation which included electrical, plumbing, plastering, repair and painting work. Avash and his team have been great! They were hired for our new home renovation and did an amazing job. They were on time, tidy, provided professional advice and worked long hours to ensure the project was completed within time. The after service has been great too as they’ve returned to rectify any small nagging issues promptly, we really appreciate their hard work and dedication with the hope to use them again in future. I would highly recommend them!

Painting & Decorating- 1 Jul 2017
I would highly recommend these guys. They did a very high quality job decorating my lounge, dining room, hallway and stairs. They started the job on time, worked through the weekend to get the job finished in good time, left the place clean and tidy at the end of every day, and cleaned up immaculately at the end of the job. The price was also very competitive compared with other quotes I received. I hope they are available again in a few months time when I have more decorating that needs to be done.
