Outstanding Work. Highly Recommended

Freddie and his team did a complete re-fit of my bathroom to a very high standard.  The team were incredibly hard working.  In my opinion they deserve a ten star rating and I would confidently recommend them to anyone looking for a reliable, efficient, honest and personable group of people to work in their home or business.  They turned up on time and left the workplace immaculate every day.  They were respectful, considerate and good-humoured.  It is rare these days to encounter such a good professional team.

An exceptional, hardworking team

The relationship between a builder and their client is always based on trust. Will they turn up when promised, deliver on time, respect the impact building work is having on your home or business?

My experience of such services in the past has been mixed, to say the least, and I suspect many people would say the same. Freddy Mani and his team are without doubt the best builders I have ever encountered. Well–skilled in delivering an architect’s vision, they can also adapt and change tack when necessary, offering their own solutions to problems you may meet along the way. They respond with enthusiasm, rather than scepticism, to innovative ideas but are also ready with words of caution or advice if needed. Their range of experience is impressive, and they are as at home working on ancient, listed buildings as on new-build constructions. Most importantly, if you are letting them into your home, you will find them respectful, trustworthy and super–tidy and they are swift to respond to any follow-up needed after the job is completed. All in all an exceptional team who fully deserve a five-star rating.
