Finding it hard to find  dependable General Builders in Mill Hill?

Our Mission

My name is Ros Leonida and I founded Onifit as a continuation of a family business that was running for many years.  I have had a range of jobs over my working life and picked up many valuable skills in and outside of these jobs. So this has given me the pleasure of becoming a multi skilled General Builder in Mill Hill able to cover a number of areas involved in Home Maintenance and Improvements.

My aim is to create life changing work and build great relationships with my clients resulting in 85% of my work being referred by YOU.  Having worked for a Five Star Global Official Airline customer service in Emirates, from start to finish I aim to please all of my customers and go above and beyond with hard work, attention to detail and commitment to complete all jobs to satisfaction.

Does that sound like someone you would like to take on your current Home project? Then maybe it's time you consider trusting in me.

Very happy crossed arms Personal Trainer in Mill Hill

I am proud to say I know my way around Electrics, Plumbing, Tiling, Painting & Decorating, Cleaning, Assembling, Carpentry, Alarm Systems and Cameras, Ethernet Cabling and many more fields just giving you an idea of the jobs I can carry out.

I take pride in my work and can turn my hand to many things. And that said I know my limitations and I will not take on jobs I am unable to carry out.
