We were able to find a very good residential contractor from the list of companies on Local 3s website. We decided on Lakewood Plumbing to fix our drain problem. We are very happy with this company and their plumber, Joe V. Joe was able to get to our house within 24 hours of our call and he was not only good about fixing the problem, but explained what happened and went above and beyond to make sure we understood how to avoid it in the future. Joe was friendly, knowledgeable, and a pleasure to work with. On top of all of that, the price was very fair. We would absolutely use a Local 3 company

Pros:
High paying
Pension after 2 years
Good training for apprentices
Cons:
Does not hold their contractors accountable when they lay employees off by the bunch
Is really lacking work right now and that means less work for everyone in the union
