Extensions- 25 Apr 2020
Financial restrictions meant we had to change from an extension to simply improving the existing house. I gave Vlad a call on a friday and his army was ready to start the very next Monday morning. All would have been finished in less than 2 weeks but the unexpected Covid-19 lockdown on 23rd March meant that supplies were harder to get. Very pleased with our brand new house. Good job done on new Electrics, Kitchen, Bathroom and plumbing and he even helped fix our D.I.Y furniture at the end. Will definitely use VM on our next project.

My partner and I are so pleased with the extension work which Paul & team carried out, not just what was done but also the way it was done. All of the team were great - they turned up when they said they would, and simply got on with their work, They were all polite, friendly, helpful, conscientious, and made several suggestions to improve the finished work. They frequently checked on details with us as the work progressed to ensure that we was satisfied and our needs were met, we was extremely impressed with how they understood & handled our neighbours, will definitely use again in future projects!

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.

Groundwork & Foundations- 26 Feb 2025
I hired John to build a concrete base for a garden building installation and he did a great job, resulting in follow-on work for him laying a new Indian sandstone patio in front of the building, which he also did to a high standard. After receiving several quotes from different firms, I selected John because he asked the right questions, clearly thought about the solution and was interested in ensuring the result was the right one right for me. He's a lovely bloke and a pleasure to have working here. He works on his own and for the most part keeps himself to himself, wasn't fussed about tweaking the scope here or there as the plan developed and kept the place pretty tidy throughout. I will be using him again for sure, so I wholeheartedly recommend John for any work you're considering hiring him for.

Restoration & Refurbishment- 1 Feb 2026
The WORST experience I have ever had with a tradesman. I would strongly advise others to stay clear. There was no schedule of works at any stage. Adrian failed to plan, failed to communicate agreed works, & did not even tell his own workforce what they were meant to be doing. There was no evidence of professional oversight or management, resulting in chaos & extreme delays. I was repeatedly misled. He stated that Building Control had been contacted & paid for; but when I contacted them directly they confirmed no application or payment had been made. He damaged my property & instructions were ignored. He was rude, aggressive & shouted at me in my own home, which I found intimidating as a woman. Neighbours also complained about his behaviour. Despite multiple extensions, the job was left unfinished with little communication. He caused significant stress & a serious loss of time & money. The matter is now being resolved through the courts. I would NOT recommend him under any circumstances
