“We wanted to redesign our daughter’s playroom into a library. Nenad and Alex were recommended to us and made all the difference in finessing the design, suggesting lighting options and ensuring that we had thought about all the options. They are exquisitely thorough in their approach and their craftsmanship is an absolute pleasure! They takes pride in their work and as a result we have a beautiful library that meets all our needs. I would not hesitate to recommend Nenad and Alex”

Detailed reviews
“Nenad and Alex made some bespoke cupboards for our living room to hold our washing machine, tumble dryer and to provide additional storage. They were fantastic throughout the whole experience and offered invaluable advice. Both of them were very professional and accommodating and the end result is fantastic. Nothing was too much trouble and would highly recommend them.
Nenad and Alex came highly recommended and did not disappoint. They carried out some restorative work on walls and ceilings damaged by a water leak and their finish was perfect. The old and new portion of the ceiling and walls are indistinguishable from each other. Usually, when I have some decoration work carried out I keep finding things that could have been done better, in their case I keep finding little details finished really well that I hadn't noticed before. Alex and Nenad takes pride in their work and it shows in their finished work. And to boot, they are punctual and tidy.

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever pay a large deposit up front. Agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow. Both are red flags for an unaccountable job.
