What is my job

What is my job? 
I work with my hands 
To fix and mend 
Various pipes and odd ends 
I solve heating, water and sewage problems too 
I repair pipes, fixtures and sinks as well as loos 
I do cookers, dishwashers and anything else you need 
You will often find me bending on my knees 
If you need me call me 
and I will be there 
With a quote and a coke, if l dare. 
Have you guessed what I do?
