Extensions- 16 Oct 2023
Mariusz & his team are amazing, from start to finish they have been fantastic & we cannot recommend them enough. We met with a couple of builders for quotes & felt like our project would be in good hands with Mariusz, we instantly liked him & had a good feeling. He was happy to talk through everything with us, answer our questions & nothing was a concern or a problem, this continued throughout our whole project. Communication was faultless throughout, which in our past experience is unheard of & Mariusz was on site multiple times a week. The team were polite, hard working, tidy & professional. Andrew & Pavel were the main guys on our build & they were amazing. They arrived the same time every morning & worked so hard 6 days a week. We cannot believe how quickly & professionally they carried out each stage of the build, which ensured all timelines were met. There was no cutting corners, the quality of work was excellent, with many of our neighbours coming over to comment on their craftmanship, especially the brick work. Our local council building inspector assigned to our project was satisfied & complimentary of the build throughout, no concerns were raised. Doing any size home renovation project & finding someone you can trust & rely on can be daunting. However, Mariusz & his guys really are who you hope to work with. If you are looking for a team then look no further, you will be in safe hands. It's been an amazing journey & a pleasure to work with Mariusz. Thank you

Extensions- 13 Jun 2020
Carlos and Luzianna did our kitchen extension in 2017 and we were very pleased with the quality of the work they did. We hired them again in 2019 to redo our living room and front garden. Again we were pleased with the result. In both cases we were living in the house during the construction and they did everything they could to be considerate and clean. We would definitely recommend them.
