Extensions- 2 Nov 2018
Building a 2 storey rear extension and hired Jamal to do the Block work. Initial ground storey heavy Hollow block walls for the 3 x 3m extension completed in only 3.5 days by Jamal himself with no extra help. Hardworking young guy. I was nearly bedbound with sciatica and in great pain and he immediately offered to source and buy on my behalf extra blocks required to relieve further stress on me. Very helpful, reasonable and understanding. Explained anything I asked him diligently. Knows his job and I will be calling him back when I have the money to complete the block work for the 2nd storey.

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.

Bathroom Fitting- 26 Mar 2026
As a property developer, I frequently use MyBuilder to find tradespeople, and I can confidently say that Vas is one of the best handymen I’ve come across. He is polite, reliable, and highly professional in his approach. What stood out most was his ability to complete the work to a high standard without requiring any supervision, which is invaluable in my line of work. The job was carried out efficiently and with great attention to detail, giving me full confidence in the quality of his workmanship. I would not hesitate to recommend Vas to anyone looking for a dependable handyman, particularly for bathroom-related jobs or general maintenance work.

Kitchen Fitting- 20 Dec 2025
Great service from the builder. He listened to everything that I wanted & provided really helpful advice. He completed the job to a great standard and am really happy with the results. I wanted new kitchen countertops and electric hob/sink and tap fitted instead of remodelling my whole kitchen. I also felt very safe with leaving him to work alone in my house. Would recommend and use again. Thank you!

Flamur did a great job on repairing, plastering and painting our damaged walls and ceilings. He also matched and replaced a wooden ledge which was damaged. He was very responsive, knew exactly what was needed to make a perfect finish and completed the works in a timely manner to a very high professional standard. He also helped source materials that we needed. We were very pleased with the outcome and would use him again. We couldn't recommend him highly enough.

Would highly recomend Tony and his team, clearly know what they are doing and have done and seen it all before! We had a rear and side extension, Tony kept us well informed throughout the job what the next stages will be etc, was always on hand during all stages every day, even weekends when needed, nothing slowed the job down and we were done in great time! Nothing was not possible, even down to me being fussy with a wall, its beyond my expectations! Thank you and your team Tony 😊

I could not have hoped for a better team than with Sebastian and Johnny. Always on time, well organised, polite and helpful with myself and the neighbours. They completed in a record time all our garden which was entirely levelled, all drainages, foundation and structural works up to DPC level of the extensions. Strongly recommend them. Will call them again.

Hard Flooring- 23 Feb 2020
Andrei provides great communication and very professional service. He was very flexible and worked extremely hard to get all the work done in the shortest time possible, but he did not compromise on quality. He worked very efficiently and considering all the work he had to do, he still left the house clean and tidy. The attention to detail was second to none. I’m extremely happy with my new flooring and would definitely recommend.

Andy and his team did a fantastic job. Our neighbours were very uncooperative and restricted noisy working hours quite severely but Andy was very accomodating. He is very easy to talk to and happy to discuss ideas you may have concerning the build. I would definately reccommend him. We are delighted by the extension and will definately use Andy again in the future. Thanks!

What experience do you have with similar extensions in Rainham?
