Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Bathroom Fitting- 21 Jun 2022
We are not entirely satisfied with Ludovic's work. Some of the tiles were not cut to the correct messurement which left big gaps in between. Worse still, the grouting was very messy and did not have a smooth finish. We will now have to get another Tiler to redo some of the tiling work. Overall, it was not a professional job and we are not very happy with his workmanship.

Conversions - General- 24 Apr 2026
I recently had extensive work completed in my flat by Vas, and I couldn’t be happier with the result. The service was excellent from start to finish. Not only was the quality of the work consistently high, but the whole experience was smooth and stress-free. What really stood out was Vas’s level of skill and versatility. Every aspect of the project was handled with care and professionalism — from plumbing and new water heating pipes, to new electrics, installing a new kitchen, laying a beautiful wooden floor, renovating the bathroom, and even replacing doors with a sliding door system. Each element was completed to a very high standard. On top of that, Vas was friendly, proactive, and easy to communicate with throughout. Nothing ever felt like too much trouble, and it was clear he takes real pride in delivering great results. It was genuinely a pleasure to deal with Vas, and I would highly recommend his services to anyone looking for reliable, high-quality work. Thank you again!

Bathroom Fitting- 14 Jun 2026
George came to my rescue after what initially seemed like a straightforward bath replacement turned into a much bigger job due to unexpected floor damage underneath. He was very reliable, knowledgeable, trustworthy, fast, thorough and incredibly easy to deal with. He kept me updated with photos/videos, explained everything clearly and acted quickly to find the best solutions. When we discovered bigger issues, he strengthened the floor properly to get the job right. He also went above and beyond on several occasions, carrying out additional jobs free of charge, including replacing a faulty light switch that he noticed himself. Despite the unexpected extra work, he completed everything quickly and with no fuss, finishing ahead of schedule and to a high standard. Finding contractors like George is rare. I was so impressed that I've already asked him to carry out further work at another property. Excellent work – highly recommended. I will definitely use George again.

Extensions- 24 Mar 2021
Rhys and his team have good skills and quality on all the extension works including big/long steel beam installation, extension connecting to the existing structure, complex loft conversion and architectural curve hung ceiling. For the internal decorating, they completed a beautiful bathroom for us. The staff were polite and friendly and also provided technical suggestions to optimise the design time to time. I would recommend RJB for similar size extension construction projects and decoration work.

Fletcher and his team did a 5 metre extension on my kitchen, installed a new kitchen, new doors and new floorboards throughout the downstairs. All members of his team were absolutely outstanding. The workmanship looked extremely professional and it turned out so much better than I expected. If there was ever a problem, it was never a case of ‘we can’t do that’ there was always a solution and I never felt stressed as I knew that whatever cropped up, they dealt with it. They were all so friendly and I felt at ease with them all the time. When I went to work, I left them to their own devices and they always locked up perfectly for me. I can’t recommend them enough and I will certainly have them back when I need more work completing.

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.
