Restoration & Refurbishment- 4 Sep 2020
Octavian is a really great guy, very reliable, never disappoint, maintained good communication with us all the time. As a customer, obviously the most important part is great craftmanship, we have used other teams before and you can easily tell the difference between his work and the others. From things such as painting (you can tell they have paint and sand multiple times to provide such great finishing), tile installation (the gap between each tile is tiny, and they are very flat), Octavian’s team can get them all done. This job involves a full flat refurbishment, so the flat was completely stripped, knocked down a few walls, install new pipes / wire etc. During his work he has spotted many things that we have not noticed before. Unlike some other contractors who do not care, they will just finish what they were asked to do and leave. Octavian spotted it and recommend us the best solution for it, to provide the best outcome for the project. It is important to find someone who do care about the customer and the project. We will use him again for our future projects. Thanks. Tommy

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.

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

My name is Paul and I've been in the building trade since leaving school 40 years ago. I started out as a steel fixer, then went to college to gain a City & Guilds Level 3 in carpentry & joinery. Over the last 40 years I have become proficient in all aspects of the building trade. I specialise in extensions, loft conversions and refurbishments. I have had refurbishments featured in Home & Gardens Magazine and The Daily Telegraph. I live in Sidcup, but am willing to travel. All my work has been on personal recommendation. I pride myself on providing a quality service at a fair price and support the client from the beginning to the end of the job.

Extensions- 23 Feb 2024
I’m literally blown away by this team of guys. Professional from start to finish. Danny quoted promptly in the timeframe he promised after he viewed the project. He was clear about what he could deliver with the budget that I had and made suggestions using his knowledge that helped me achieve the dream garden room that I have always wanted. His team turned up at 8am sharp and work started at 8.01 every morning. It’s clear that Danny surrounds himself with professionals that he can trust to execute his promise and deliver the quality he expects, and that his clients pay for. Another plus is that he was extremely accommodating to some changes that I asked of him during the build which he also didn’t charge for. Nothing was an issue to this man and he clearly operates a “client first” attitude which was apparent also when he visited every second day to check progress and quality. Lastly which is also something that I didn’t expect is that he had the extra materials that were not used collected and credited to the final bill. If I had more time I could go on all evening but my final words are. Look no further. With Danny you have found an honest professional business man that takes pride in his work and I am happy that I found him and his team. Good luck with your project.

Restoration & Refurbishment- 28 Dec 2015
I did quite a bit of research before choosing Battersea Builders. They didn’t come in with the cheapest quote but I never base my choice on price alone. And it wasn’t miles above the other quotes I got. Instead, I chose them because they ticked a lot of boxes including a) good independent reviews, b) a dedicated PM, c) qualifications, d) quick responses, e) a decent website etc. Overall, they did a fantastic job. The quality of the work and finish is really good. The PM, Tommy, was really helpful throughout and the team was very polite and conscientious. They were also on site every day as promised and didn’t play that old builders trick of getting the job and then going offsite to secure another job elsewhere (resulting in the deadline being missed). Was it perfect? No, but then not many projects are. I have a few minor comments including the fact there was a misunderstanding about the quality of bathroom cupboard I needed so the original quote was insufficient and costs had to be increased half way through the project. Despite this issue, Tommy did his best to keep the extra costs down. One other niggle was that I asked them to keep all the manuals and instructions for all the fittings but they threw them out. Not a big deal but quite annoying. Overall, it wasn’t cheap but I would use them again because the work was done to a high standard and the team were a pleasure to work with.

Very impressed by Eugene's work. I hired him to build a bin shed for my front garden. He took the time to understand what I wanted and work out how he could combine the look I was after with a stable structure. I am so pleased with my new shed. Eugene is trustworthy and reliable and I will hire him for other work in the future

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.
