...look like they're very good. I've got a boat load going in right now. They operate nice, look good. A local contractor is putting them in. It's who he uses. $500 a pop, installed.
My CPA used Thompson Creek and loves them, but I do not know if they come down to SOMD. They did not cover central MD or I would have had them come out. $700 per.
Long Windows, well, all I can say is they have some work to do on customer service. Everyone asked that you and your spouse are there for the on site visit. I told them that wasn't going to happen and we had a date. They actually had someone call me back a few days later and TOLD ME it is THEIR policy that both people be there. I was nice at first and told them it would just be me. She insisted, actually insisted. and I said, that makes it easy, tell them not to come out.
So, my feeling is that they are growing too fast and customer service has been neglected in the process. No one called me back or tried again or sent flowers or candy or anything. Seems I didn't matter. Can't say anything about price or quality because their policy was to not come visit my project.
Of course, based on that, I can give it a pretty good guess.
