I've had good luck with Procraft for windows and doors. The customer service rep we worked with on both occasions, Samir, was nice and helpful. The reps come bearing binders of product brochures showcasing the doors and windows that Procraft sells and installs. We went with Milgard windows to replace our house's original windows. I don't remember what brand of doors we bought, but we got a solid wood one for the front and a metal door for the side of the house. We were advised to stick with our plain, but functional solid wood basement door. I appreciated that the rep would be honest and suggest we stick with what we had even though it probably meant less commission for him. The windows and doors have always arrived looking just as we thought they would and the quality has been great.
The installers were different each time, but both groups were professional and efficient. When they leave, you would hardly even know they were ever there. I was home when our new doors got installed and the guy even unscrewed and rehung our bathroom door and tried to fix up a scratch on the tile when he used the bathroom and noticed the door wasn't shutting quite right. My only complaint is that they didn't install a peephole in the front door, but I didn't remember until after they'd left. I'm pretty sure it was added to the work order and I feel confident they'd come out and install it now if I could just get off my butt and call them about it.
Our doors and windows were always installed in one day and within several weeks of the original estimate and order date.
I don't know if they do installations of products not purchased through Procraft...
