Best Quality Builder

I would never recommend this contractor to anyone unless you want a headache and poor service.  For my job he hired very poorly trained, poorly qualified and often surly subcontractors to do the work.  The HVAC company he employed (although pleasant to work with generally) made many mistakes in installation some of which probably cannot be fixed due to the way the attic furnace was placed and installed.  The humidifiers that were part of the contract never worked and they were unable to come up with a solution.  In addition, the hvac company was lazy in their installation and never installed a drain pan under the airconditioning coil in the attic (I guess I just have to take it on faith that there will never be a leak?) and instead of properly installing the humidifier drain line into the pvc pipe, they cut a hole in the pipe so that if there ever is a leak, we will surely have damage at the level of that hole.  Did Greg ever supervise or review the work that was completed or repair work?  No.  In fact after the first day he was never on the job site except to collect checks.
Greg was often impossible to reach and would not return phone calls in a timely fashion.  The company he hired to repair floors damaged my dining room table (and he never offered to have it repaired but instead directed me to his project manager to "look at the damage"), and were generally extremely rude when I asked them to cover doorways and furniture (like the dining room table before they damaged it with varnish) with plastic when repairing/patching floor underneath radiators which were removed.  They used cheap machines and did the minimum amount of work possible in fact not even finishing all of the flooring patchwork.  Another subcontractor came to finish patchwork in other rooms.  
From the beginning Greg obviously did not want to have to pull permits to do the job because he knew that then inspections would be required and possible problems would be uncovered.  Therefore, despite asking him multiple times about his responsibility to get permits (as per the contract), work commenced without them and not surprisingly, the village found out and charged a fine for lack of permit (at least he paid for this).  The plumber he subcontracted also was very poorly trained and caused multiple problems including an attic leak which damaged the ceiling below causing extensive repair.  The plumber also for some unknown reason unplugged the ejector pump in the basement and forgot to plug it back in.  Result:  sewer water back up in neighboring basement bath.  The plumber also did not connect the water line in the basement system and that had to be connected by the hvac company later.  As if that were not enough, since Greg directed his crew to seal up and repair the holes in the ceiling duct work  in the basement before the village inspector could come through, the inspection did not pass requiring them to rip up large sections of drywall, after which the hvac subcontractor had to install insulating tape at all the ductwork seams--which should have already been done-- and repair the drywall again (more time and frustration on my part).  
Overall, we paid a lot of money for a lot of hassle, poor supervision, poor installation and a system that never completely worked as contracted and paid for (still don't have a working humidifier in either system) and now we are having to pay a lot of money to a new company to fix their many mistakes.  

Greg is very responsive in terms of giving you an estimate to do the work. Because of the overall quality of the work, and the references, I would use this company again on another project. My only complaint would be that Greg needs to learn a little in terms of customer service. For example if your people are going to be on another job, or you know there may be some delay to starting our project from the date that was given, it makes sense to me that he should be the one to call to let us know when there was going to be some sort of delay. Otherwise, there were of couple of small detail issues that I am a little annoyed by. Like the paint that was put on the new vent for the kitchen could have matched better to the new soffit and facia. Also, when I told them to make sure that the leaf gaurds on the gutters can be seen from the street, they should have gone around the whole house to make sure that the leaf gaurds were not visible. The company also did interior work for us as well to repair the areas inside that had caved in because of the water damage. They also installed a ladder so we could have access to the new atic space we had from the new gable roof. We are satisfied with the interior work. They charged us like 1,000 or so to install the new ladder, paint the hallway, and fix the damaged drywall in the basement entrance. The workers also repaired some damaged paint in the bathroom as well. My suggestion is to use this company because overall the quality of work is definitely worth the price. Like any other contractor, you have to stay on them about the details and make sure you get exactly what you want before release the last check. However, Greg does not harrass you for payments and he will get somebody out to make the changes you want. I just have to learn to be a stickler for what I want and make sure that everything is to my standards. So, some more personal growth is still in order!
