Michael came to our house at 5.30pm to fit our under floor heating in 3 rooms at very short notice. He arrived promptly and couldn't have been more helpful. He refitted our insulation as it had been put down wrong by our builder with no problem at all.

I approached Emanuel and his team for tiling of a bathroom wall. They were incredibly professional during the assessment and were very helpful in working around my limited budget. They showed excellent craftsmanship and attention to detail, taking the time to sand down the cut tile edges. Most importantly, Emanuel and his team were very transparent with their labour and material costs with receipts for breakdown. This has won over my trust and I will surely enlist their expertise again soon.
