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.

Landscaping- 18 May 2021
Joe was professional and responsive for my posted job to do fencing and wood trim repairs. He was able to provide a quote quickly and did the work in quick fashion. I wasn't quite sure what was feasible, but Joe was able to provide good guidance on what could be done for the repairs. The quality of the workmanship seems to be high, and I am pleased with the result. I would definitely recommend Joe for this type of work.

Bagnall Brickwork provided great service when I requested a quote to reinforce a wall for a heavy 50kg TV mount. Although they didn’t end up doing the work, their honest advice helped me realise that reinforcement wasn’t actually necessary for my situation. Thanks to their guidance, I was able to find a much more cost-effective and appropriate solution without compromising safety or quality. This experience shows their ethical approach - they prioritise giving trustworthy advice over making unnecessary sales. Highly recommended for anyone seeking professional, reliable, and principled brickwork or building services.

Aaron and his team were fantastic! They worked tirelessly to get the build completed on schedule and were tidy and considerate in doing so. They consulted and updated me all the way through the build and were accommodating with a few last minute changes on my end. They also refurbed a few rooms while doing the main extension and were hugely accommodating in managing that in such that we could move our daughter from one room to the other minimising the disruption our end. I couldn't recommend them enough. Good, honest, integrity and hard working. A rarity in the trade now days!

Ryan is absolutely fantastic. Whilst new to mybuilder, it doesn't mean he's new to the world of carpentry. His work ethic is second to none and quality of work meticulous! We absolutely love our new flooring and it's been put down so incredibly well. He was also able to advise us on lots of different future jobs and offer quotes for these too. All very reasonable considering the quality this guy's works to. Hands down worth that little bit more to employ Ryan, you won't be disappointed one bit!

Two rooms in one day. The work was done to a high standard and everything fit as it should. He left the job tidy and neat, when I walked into the room, it was if the floor had laid itself. We also hired him to install a double glazed window for us, again work done excellently and no less left
