We can whole heartedly recommend Mick and his team; in fact since he has finished our loft conversion we have recommended him widely.  Mick takes time to explain what is happening at each stage of the build and is happy to give advice as and when needed. The team were so efficient in getting the dorma up and then worked hard to do all the messy jobs whilst we were on holiday.  Throughout the project, all of the team were efficient and tidy.  As we neared the end of the project, Mick was very helpful. There were a couple of things we wanted altering and he was quick to fix them.  Even towards the end when I couldn't get the new bed in - the team came to the rescue- and as always with a smile upon their faces.

The workmanship has been first class and we have had lots of people compliment the finished project.

If we need any more work doing, we won't look any further - they have our full stamp of approval!
