We replaced all of the sing-paned windows of our older home with new double-paned, vinyl windows from Oasis Windows. The salesperson got back to us with a quote in a timely manner. We placed the order. Two weeks later the windows arrived - exactly when the Company said it would arrive.
The windows were very well made and very well priced, the best price we found. The fact that the service is great and they deliver when promised made ordering from them a pleasant experience. I've dealt with A LOT of contractors and suppliers who almost never deliver on time so when I find one that does, I'm very loyal.
