Very few contractors understand and explain the difference between mediocre and high quality materials. These guys work with your budget and explain how choices will effect it. Great to work with keeps the schedule updated and will do what it takes to ensure the final product is great looking and built with the highest quality

Didn't respond to my first message regarding concrete work. Called back after second message and claimed not to have gotten the first one. Told me he'd have somebody call me. Never did. Would not recommend based on bad communication.

What 605 Companies INC is registered to do
The State classifies 605 Companies INC as other/undefined. That classification comes from the registration itself, not from us. It describes the work the business registered to perform, and it is not an assessment of skill or a limit on what they may quote for.
