We recently completed a full house refurbishment including a 4-metre rear extension, dormer loft conversion, and complete interior renovation with ALMO Property Group—and I genuinely couldn’t recommend them more highly. From the very beginning, the team managed everything seamlessly, from planning and design through to execution. What could have been an incredibly stressful process was made smooth, organised, and surprisingly enjoyable thanks to their professionalism, communication, and attention to detail. The quality of workmanship throughout the project has been exceptional. Every stage was handled with care, precision, and a clear commitment to delivering a high-end finish. The team were reliable, efficient, and always kept us informed, which gave us real peace of mind. A special mention has to go to Ameer, who was absolutely outstanding from start to finish. His dedication, responsiveness, and willingness to go above and beyond made a huge difference. He was always on hand to answer questions, offer solutions, and ensure everything ran perfectly. ALMO Property Group have completely transformed our house into a beautiful home, and we are beyond happy with the results. If you’re looking for a trustworthy, skilled, and professional team, I would highly recommend them.

Groundwork & Foundations- 7 Nov 2024
From start to finish, Bogdan and his team were exceptional. After dealing with a previous builder who caused numerous delays, I found SBG Services. Bogdan came by the same day to assess the job and impressed me with his extensive knowledge. Given my tight schedule, he got to work immediately. I’ve never seen a builder work as hard as his team; they labored tirelessly from morning to night to ensure the project was completed promptly without compromising quality. Every trade I've had since has commented on their attention to detail. In just three weeks, they completed two extensions and transformed my garden. I will definitely be calling Bogdan back to handle my front garden early next spring.

Extensions- 19 Jul 2021
Jitender/Tinku and his team were excellent from the first time we met. They provided us with ideas to better our layouts, helped with sourcing a number items and put us in contact with suppliers which helped us achieve more competitive prices. I was kept updated with the progress regularly and most importantly the project was completed on time and within budget. Shah Builders take real pride in their work and it shows in the finished product. We are very pleased with the outcome of the project and have recommended Shah Builders to friends and family.

Extensions- 8 Dec 2023
I recently had the pleasure of accepting Jagdeep on a substantial renovation project. Initially, I was a bit apprehensive as there were no existing reviews to gauge his work. However, after seeing some of his previous projects, I decided to take a leap of faith - and it turned out to be the best decision I've ever made. Jagdeep's approach to our project, which started merely as a rear extension and shower room, was nothing short of exceptional. His remarkable craftsmanship and attention to detail soon convinced me and my wife to extend the scope to a full renovation. Throughout the process, Jagdeep and his team displayed an extraordinary level of skill, professionalism, hard work as well as trust (very rare these days). No task was too challenging, and his willingness to prioritise our needs and provide thoughtful advice was truly comforting. It's rare to find a builder with such dedication and expertise. Jagdeep is undoubtedly one of the best builders I have encountered. My heartfelt thanks to Jagdeep and his team for their outstanding work. Rest assured, for any future projects, he will be the first person I call. Thank you, Jagdeep, for turning our vision into reality, which more than exceeded our expectations!
