Construction Labor Costs
Vary from state to state and from zip code to zip code etc.
But for the most part the costs for labor are pretty straight forward.
For example your cousin might know how to install a door but how extensive is their knowledge, have they done it before and how did the project pan out?
Another example; your furnace has problems and your friend may have gone to a school to get an HVAC certification and they may only have a certain amount of knowledge concerning this yet on the other hand you have someone who has extensive knowledge with complete HVAC systems.
You will obviously get 2 different prices based on knowledge and experience.
There is more on this but you can calculate the hourly rate or a flat rate based on experience, knowledge and performance.
You may get someone on the cheap as far as labor is concerned but what kind of job will they do?
