  G2 recently completed a reroof of our home and I couldn't be more pleased.  Working with Jeff was a pleasure because his communication and knowledge made the process stress free for me from start to finish. And his crew worked hard to get it done quickly and their workmanship was second to none.  Thank you G2!

  I just got a new roof yesterday using G2 Construction. The process, from start to finish, was transparent, smooth and respectful. The crew came at 7 am and finished the same day at 7:30 pm; leaving without a trace except for the new roof. I immediately went up on the roof (which I have done for 30 years) and it was magnificent: impressive overall - finishing, materials, - a job well done. I will recommend them to all I know and even strangers. It is much appreciated.

  Fantastic experience with Jeff at G2 on several home construction projects. I was most appreciative of his attention to detail, ownership of the projects, fantastic communication, oversight of all of the work, accurate bidding, and willingness to seek multiple bids that met our budget. We are very happy with the results and will call Jeff at G2 for our next project.

  G2 Construction did an amazing job re-doing all our windows. Came out and measured multiple times, were very flexible with schedules. The framing of the windows is wonderful, even when some hiccups came- handled professionally and wonderfully. Jeff handled everything wonderfully. And Steve and crew did an amazing job removing, installing, mudding, painting/staining, and framing the windows.

  The project ended up exceeding our exceptions - full kitchen and basement renovation.  Absolutely love the new kitchen - much more functional and the materials/finish are excellent. Not at all surprising that we ran into building code issues in a 50-year-old house - and they were all resolved to the satisfaction of the inspectors.

  G2 just completed the 2nd home remodel project that they have done for us.  The project they completed 5 years ago was the reason that our house sold quickly during the time when house sales were dropping.  Our buyers loved everything that G2 did.

They just finished a kitchen/living room/master bath remodel in the home moved to, and did another incredible job.  They completed the project on schedule and actually under their estimated budget.  Their project management is exceptional and their new software allows the client to easily track the project and communicate with G2.

All the G2 crews, their subcontractors and the material suppliers they referred us to were professional, and made suggestions that improved the project.

Many thanks to Nick Klostermann, Alex, all the G2 crews and subcontractors for another great job.  We could not be happier with the job they did.
