Plastering- 16 Mar 2020
Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects. Thanks Zai

Conversions - General- 11 May 2016
Anthony and team. Turned up when they said they would, and worked really hard to get the job done quickly. The job involved removing a section of the outside wall and window to replace it with a patio door which they had to remove the existing radiator which, was underneath the old window. Excellent quality of workmanship, Ensured minimal mess throughout the job, and cleaned up well after. i was impressed with finished result, as it looked like the patio door was originally there instead of a window. Then i asked if they would replaced my backdoor and it was the same result. Would definitely hire Anthony again. Five stars

Conversions - General- 15 Apr 2019
The job was done immediately and took just half of the day. Was very good communication between the date we contacted Johny and he gave us very good advice. He had patience to all our questions and gave us a lot of indication and options comparing with other builders. In the end, he did more jobs for me because he has a big company, so we did with him the plumbing system as well. Definitely recommend this person and his company because they did the jobs properly and very quick, no need to wait 3 weeks or even worse 1-2 months to book them.
