How to evaluate J Synergy Green, Inc.

Before hiring J Synergy Green, Inc. for general contractor work in East Rockaway, take a few minutes to verify their qualifications and confirm they are the right fit for your project.

Ask about project experience

Ask J Synergy Green, Inc. how many projects similar to yours they have completed in the last 12 months, whether they will be the primary on-site team or are subcontracting, and how they handle change orders. Request two or three local customer references and actually call them — reviews on Google are useful but a five-minute conversation reveals much more about how a general contractor actually shows up.
