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!

Architecture- 4 Jun 2026
I recently worked with this structural calculation engineer for a project that required precise drawings, and I couldn’t be happier with the outcome. The calculations were spot-on, and the drawings were clear and detailed, making the process seamless with my builders. Not only was the quality top-notch, but the pricing was fair and transparent. Communication was excellent throughout, and they delivered on time. Highly recommended!

Bathroom Fitting- 14 Mar 2025
My previous bathroom fitters did a very bad job with the bathroom and cloakroom toilet and left it unfinished. I am so glad I went with JM Building service as Joe and Martin completely transformed both rooms. They rectified the previous fitters errors and completed the rooms. Joe didn’t just rush through the job to get it done quickly—he took his time, ensuring every detail was finished to a high standard. He worked meticulously, making adjustments until everything looked exactly as it should, rather than settling for ‘good enough.’ His dedication to quality and precision was evident throughout, and the end result speaks for itself. As well as being very good at what they do, they are friendly, reliable, trustworthy and hardworking. I have already booked them in for another job and requested a quote for another. I highly recommend JM Building services for their professionalism and craftsmanship.

Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

Landscaping- 7 May 2026
“We recently had our landscaping redone along with new turf installation, and the results were excellent. The team was professional, punctual, and paid great attention to detail from start to finish. They completely transformed the garden, leaving everything neat, tidy, and looking amazing. The new turf was laid perfectly and has already made such a difference to the overall appearance of the space. Communication throughout the project was clear and friendly, and the workmanship was top quality. Highly recommend to anyone looking for reliable and skilled landscapers.”
