We had a few hiccups on the day-of, but overall our experience with Galaxy Windows was very positive.
Dimitri was great, he came to the house, took measurements, offered us two different brands of windows and explained the difference between them, and had several catalogs of front door styles to choose from. Once the order was placed, Alex e-mailed a computerized drawing of the door to confirm everything was exactly as we were expecting so that there were no surprises.
We had just had our driveway paved, so the crew wasn't allowed to park in our driveway which caused a big delay while we debated delaying the job. Once we got rolling they were fantastic, very clean, the windows look perfect, the door is solid. The stayed until 9pm that night trying to get the entire job done ( 7 windows, 2 sliding doors, 1 front door) but they just couldn't do the last sliding door. They returned a few days later to finish the job, but in the meantime our property was cleaned up and the last door was stored in the garage and out of the way.
One major bonus to going with Galaxy vs anyone else we had quotes from: they'll install new wood trim around the windows inside the house. Everyone else would give you a wood box, but no trim to finish it off (or they'd give you you a finished, cheap looking vinyl frame).
We opted for the more expensive brand of windows and they were worth it. The house is quieter inside, everything opens incredibly smoothly, and our neighbours all compliment us on the fresh look. Thanks Galaxy!
