Joinery & Cabinet Making- 16 Dec 2022
I'm so happy with shelving that ozzy and his colleague made. Ozzy took the time to understand want I wanted (floating alcove shelving) provided a clear and comprehensive quote, and kept me updated on completion of the shelving in his workshop. On day of installation, the guys were lovely and friendly, they went the extra mile in dealing with floors and walls that aren't at all straight, and the finished result blew me away, it's transformed the space completely. Such a pleasure to deal with, would highly recommend and i would definitely use them again in the future.

Landscaping- 13 Jun 2024
Work done: new retaining wall rebuilt about 900cm high. Two new steps leading onto the lawn built, patio re-grouted, existing garden wall, patio and front driveway power-washed. We are very happy and pleased with the work carried out by Matthew Hassall and his team. Our garden retaining wall had to be rebuilt after it had started leaning over due to work previously carried out by another company. The wall is now much stronger due to the depth of the wall at the foundations and reinforcing steel used to strengthen it. This was a highly involved job. Mathew and his team were punctual, polite and kept us informed of what he was doing at every step. We would highly recommend them.

Bathroom Fitting- 25 Feb 2022
This was the best experience I have ever had with a team of builders. Aldo and Leo were polite, organised and their workmanship is of a very high standard. They replaced the bathroom in our rental flat, and it looks really smart. They also refurbished the kitchen, replacing flooring and decorated the whole flat. We have just shown it to an estate agent as we are planning to sell it and they were very impressed. Aldo was very helpful in making suggestions of small changes that would save us money and delivered the project on time and right on budget. Would recommend them and will certainly use them again.
