Bricklaying- 24 Apr 2019
Jake and Harry did an amazing job with our front wall and fence in the rear garden. We got three quotes for the job and they were the cheapest but also came across professionally. It wasn't a straight forward job, it was was using reclaimed materials that were varying size and shapes. I was also quite particular on the look, I wanted the brickwork to match our house, they took care to match the pointing and bricks but offered advice on how we could save money whist still getting the look we wanted. They arrived everyday on time, they were reliable, honest and extremely hardworking. They also kept us in the loop throughout the work making sure we were going to be happy with the end result. I have already recommended them to friends and will use them again for our next project. Thumbs up from us!

Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.

Extensions- 24 Jun 2017
We had a large piece of work done by Johan and his team. It was a 4m single storey rear extension with new kitchen installation, converting the old kitchen into a downstairs bathroom and utility room, plus other bits and bobs like new boiler, rear patio. We got quotes from a few builders, Home Renovations weren't the cheapest, they were actually towards the higher end. But we went and saw their previous work and spoke to some of their other clients. The work was done to a high quality and the clients seemed to be happy so we decided to go with them. Johan's team are very hard working, professional and polite. Pawel and his team of builders, bricklayers, plumbers, electricians, etc. would turn up before 8am and finish at 6pm working solidly throughout the day. There is Magda as the project manager who keeps you in the loop, and answers any of your questions (which we had many). There is Michaela on the finance side who keeps you up to date with the budget. Our budget went over by 5% with "variations" (extra work or materials) but it was always communicated why and the work wasn't done without our approval. Pawel would give his recommendations but the final word would always be ours. But these things can add up. Overall we were very happy with the build, it was done to a very high standard. They also finished it before time. They said it would take 12 weeks in fact they finished it in 10 weeks which was amazing as you would normally expect these things to go over.

Kitchen Fitting- 9 Jul 2026
I hired Blend for a light house renovation. It started off really well then towards the end he ghosted me. No reason given. He didn’t answer phone calls or texts. There was no fight or disagreement. There is no decent reason why he shouldn’t communicate with a client. You can simply just say you have another job or you are not interested any longer. You don’t ask a client to buy stuff knowing you are not going to show up. It is an unacceptable and unprofessional behaviour. Because of this it’s cost me time that I can’t get back. But I guess it is what it is. I had to find another builder to complete the job. Some of which was not done properly. For example: my kitchen sink was leaking both inside and out. Had to buy a new toilet as something was broken while he was refitting it and etc. Pros: Blend is a nice and easy person to deal with. He is generally a nice guy. Tiling ✅ Cons: Finishing is not so great. could be a lot better. I also found patches and over paint on doors and others.
