Plastering- 14 Nov 2024
Very happy with the work Gesti did for us. We just brought our first home and the ceiling honestly wasn’t looking the best. Lots of cracks and slightly warping. Gesti was able to come in and secure all the cracks and plaster the entire ceiling for us. He did an amazing job. Will use him again I highly recommend. !!

We recently had our bathroom refurbished by Cubitt Wren in London, and we couldn't be happier with the result. From start to finish, they were reliable, professional, and always turned up when they said they would. The work was completed quickly without compromising on quality, and the whole team was polite and respectful throughout. Communication was excellent the entire way through. They kept us updated at every stage, answered any questions we had, and made the whole process stress-free. The finished bathroom looks fantastic, and it's clear they take real pride in their work. I would definitely use Cubitt Wren again in the future and wouldn't hesitate to recommend them to anyone looking for a reliable and skilled company.

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

Latest review:
We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

Tiling- 24 Mar 2022
Gjon and his son Julian did an amazing job tiling our kitchen floor. They were prompt in communications and completed the job within the agreed time. Left the job clean and tidy after themselves. Will probably hire them again to install a splashback later on in the project.

Latest review:
After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.

Shumon and his team did plastering, painting and decorating and they built me a fireplace and fitted in a fire. I would highly recommend him - he is absolutely brilliant and did a great job - they take a lot of pride in what they do, very trustworthy, and I am looking to have them back about Christmas time to do some bathroom work. They are very good value for money.
