Contractors / Builders for Addition

[Matthew Spyker]

Morning Hampton Roads BP'ers,

Wondering if anyone has a few reliable contractors/builders they've used for building an addition in the past? and how'd it go?

Looking at two options: Building an addition over my garage and extending my master bed-room. Looking at shelter, frame, roof and possibly electrical/plumbing depending on costs. Most of the rest of some of the electric/plumbing I could do myself.

Or turning my  garage into a mother-law-suite.

Appreciate any  help.
