Conversions - General- 29 Dec 2021
We struggled to get anyone interested in our refurbishment project originally, Mark answered an ad for a small part of the job and ended up being able to take on the whole thing thankfully. Our project was to completely strip out a 1960's maisonette flat, install internal insulation which involved extensive battening of all the external walls, new plasterboarding & plastering finishes to walls and ceilings, tiling and a completely new bathroom and kitchen install. To complicate things further, as enthusiastic DIY-ers we wanted to do lots of works ourselves as well and few builders would have worked alongside novices as well as Mark did. He was always happy to give advice or take over works when we realised they were beyond our skills or time ;-) Our project was constantly evolving and challenging - as we discovered hidden rotting floor joists and the joys of 60's engineering - door lintels - who needs those?! Mark was always there to help us problem solve and get the job done professionally and to high standards and this was all done throughout the challenging last year of lockdowns etc. Without hesitation we'd recommend Mark and his team. He was always reliable, flexible as the project developed and had excellent attention to detail and we couldn't have completed our project without him. Thank you Mark!

Loft Conversion- 31 Mar 2026
We recently hired Altin to do our mansard loft conversion and honestly, it was a really good experience from start to finish. He was always on time, worked really hard, and his whole team put in a lot of effort every day. Communication was easy and straightforward, which made things much less stressful for us. The project was finished on time as agreed, and we’re really happy with the quality of the work. Altin was also super helpful whenever we had questions and helped a lot with building control, which made a big difference. It’s quite a messy job (cutting through the ceiling and putting in a staircase), but they did everything they could to keep things as clean and tidy as possible, which we really appreciated. Overall, we had a great experience and are very happy with how everything turned out. I’d definitely recommend Altin to anyone thinking about a loft conversion.
