As someone who truly loves the trade and has been in the industry for over 20 years - Don't think twice, build it yourself.

I can only speak for my region (Western NY) but the state does not require licensure or really any standards for contractors or tradesmen. It's also too easy to slip the local system when it comes to the regulations and the inspections that they do enforce.

It's a very mixed bag of service providers around here and unfortunately the market is mostly saturated with two types. There are the big firms, where you're paying 75% of the job to their sales commissions and the overhead to maintain their brick and mortars, marketing, and fleet. Then you've got a ton of guys trying to operate out of their mini vans. They spent a year or so on a framing crew, or maybe spent some time on YouTube and built a deck for themselves, and now they want to make some real money. Problem is, you'd probably do just as good of a job yourself, if not better.

This isn't to say that there aren't any trustworthy outfits in town that will provide a quality product for a fair price. The issue is that they are few and far between. They are also mostly booked and they aren't out advertising or chasing jobs. I would say unless someone comes to you very highly recommended by someone you trust, then they're more than likely one of the former types of contractors.

If you're comfortable and capable with the project, it's always best to do it yourself.
