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.

Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work
