Rated 1 out of 5 by from New owner? Country glass came to measure my condo slider first part of June 2017. It is now sept 16, 2017 and I still have nothing in writing. I was told installation of a slider was $1,000. Two guys @$120/hour for 2-4 hours = $1000? I'm not sure what part is not right since nothing is in writing. All the reviews were written 3 years ago when Gordon was alive. Gordon started this business with his wife but now I have no idea who is running it. This company has no ratings with the BBB.

Rated 5 out of 5 by from Country Glass in Mammoth is the only place to go for windows and sliders I've replaced all the windows and outside sliders in two houses over the last two years in Mammoth. I used Country Glass both times. I'd highly recommend the work they did. All the measuring of the windows & sliders was spot on and they all fit perfectly. The office manager did a great job and was very patient with all my questions about options. Milgard has some great features and it takes some time to really pick the right windows for you. The installation was done on time and to my expectation. It was great doing business with Country Glass. I will certainly use them again for any future needs we have.

Rated 5 out of 5 by from Great Milgard Dealer As a contractor, I always appreciate a dealer that works well with me and my clients. Gordon and his team provide a great service, from start to finish, whether it is for a budget re-model or a $4M custom home. His team offers great pricing, competent suggestions to provide quality and function prior ordering, and on site presence and timely warrantee work if there are any "after install" issues. I always use and recommend Country Glass to anyone who is in the market for quality windows. Country Glass is my go to dealer for windows and glass products.
