Painting & Decorating- 21 Apr 2026
I could not recommend Tim enough. From when he came to quote for the job to completion he was very professional. We had our whole flat painted and he and his work colleague did the whole thing in 4 days. He kept us updated as he went and suggested things that needed extra work or extra coats of paint to protect the walls better. I really was very impressed by Tim and am very happy to recommend him for your painting needs.

Extensions- 25 Jul 2023
Vini and his amazing team became part of our family for the months they were working on our house! Attention to detail and great communication was a top priority for me before starting our large scale renovation, and they delivered above and beyond on every front. Vini’s team helped transform my vision into a reality - they weren’t thrown or intimidated by any of my crazy/creative ideas, and were equally ready to advise and bring constructive ideas of their own to the table, based on their years of experience. We would highly recommend Olaj Brothers as trustworthy, professional and highly skilled tradesmen.

Extensions- 26 May 2021
Ali Revani at Halibuild provided us with a quote which we accepted. 3 days before the job start date Ali Rezvani called and explained that they had under priced and they would want another £3000 to start the contract. Ali Rezvani then started the job but again admitted that they under priced the job and walked off the site several months into the project after the following major quality issues which needed to be addressed: Pouring the foundations in the wrong place, building the extension in the wrong place, building the roof incorrectly, installed roof steels in the incorrect position, built the extension rear wall too high, the plumbing to the boiler needed to be redone, all the plastering has had to be redone, skirtings needed to be redone, staircase had to be rebuilt. The list goes on and is 40+ points long. This has been a terrible experience and we face serious losses and a stressful dispute."

Fencing- 13 Mar 2026
We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

Landscaping- 16 May 2026
Very professional quotation, I chose over two others because he was very clear on where extra costs may arise and was very straightforward. He advised a different finish than I originally thought I wanted with cut stone edges and it looks even better with his suggestions. His crew were very friendly and professional. Would definitely work with him again in the future.
