I truly cannot say enough amazing things about this company. I came in hoping to replace both my…read morebedroom windows and the sliding door in my living room, and from the very first interaction, I was met with nothing but warmth, honesty, patience, and professionalism. Nan was the one who initially educated me in the office, and she was absolutely incredible. She took the time to walk me through everything, answered all my questions with so much clarity and patience, and genuinely wanted me to understand what would -- and would not -- solve the issue I was experiencing. Her knowledge and care made me feel respected, informed, and never pressured. What completely blew me away was the honesty. Despite being more than capable of selling me new windows, they were the only shop that told me the truth: the change I was hoping for couldn't actually be achieved through window replacement alone. That kind of integrity is rare and speaks volumes about this company's values. Then there's Roy -- one of the owners -- who personally made the journey out to my home to further educate me. The fact that an owner would take the time to come out himself, explain everything in person, and make sure I fully understood my options is something you just don't see anymore. He was thoughtful, thorough, and incredibly generous with his time. And yes, fair warning -- Roy looks like he walked straight out of a magazine. Be prepared to be completely stunned by the presence of an actual god while receiving some of the most honest, professional guidance you'll ever get about windows. Even though they didn't make a sale this time, Lion has earned a customer for life. I will absolutely return for all my future window needs and recommend them to friends and family without hesitation. Please don't ever change, Lion. Whatever you're doing is working beautifully. Everyone was so kind, genuine, and knowledgeable. Huge gratitude to Nan for her education and patience, and to Roy for going above and beyond by coming to my home. I can't recommend this company enough and wish them nothing but continued success.

I only had a month and I contacted several window companies for an estimate. 1) I compared Milgrad prices with Lion to Home Depot and theirs was cheaper. And also 2-3 weeks faster. Ditto other window companies on Yelp. 2) Very efficiently run. I had my measurements quickly within a day since they knew I was in a rush. I got my windows just in time installed with one week to spare. Installation was quick and easy and took 2 hours for 2 windows. They were fast on communication via email which I love. Also providing me updates constantly. I highly recommend them for window service.

What stood out most was their attention to detail. They came out a couple of times before the install just to double-check and confirm all the measurements, which gave me a lot of confidence that everything would fit perfectly--and it did. The installation itself was clean and professional, and they made sure everything was sealed and finished properly. Communication was easy, and they were responsive whenever I had questions. Overall, I'd definitely recommend them if you're looking for reliable, detail-oriented window replacement work. I'd use them again for future projects.
