I had three windows fail in less than two years after installation. After several weeks of no action from the local contractor or the company's sales person, I realized Heather in customer service at Mercury Excelum is the go-to person to resolve all issues. Heather organized the replacement of the windows with professionalism, friendliness and a deep commitment to making things right. The installer was polite and experienced with the windows so that the replacement time was very quick. With the 20-year warranty in hand, I feel confident in my purchase again and feel good about the commitment the company has for customers' experiences with the product. Thank you again, Heather.

Wonderful windows! I renovated my house and used these windows in two locations. In my kitchen I replaced two old odd shaped windows with one- three panel big window - and it is great. Opens easily and fit perfectly. I also put one in a shower in the bathroom. This one has the shade inside the two glasses (since it's inside the shower). works beautifully and fit great with the tile and existing opening.! Wished I could do my whole house with these great windows.

As the Operations Director of a nonprofit devoted to making free, critical repairs to the homes of low-income families in Connecticut, I have come to rely on the quality and affordability of Mercury Excelum’s products and, just as importantly, the outstanding customer service experience from its employees. Too frequently, the 70-100 projects we complete each year come together in a very short period of time. The only vendor which has met our difficult (crazy?) deadlines 100% of the time is Mercury Excelum. The great prices and quality, excellent service, corporate integrity, and the ability to do the nearly impossible have made Mercury Excelum our most valued building products partner.

Great company! Beautiful, quality windows at a very fair price. Staff is knowledgeable about their products as well as installation techniques and applications. Consistently pleasant experiences working with them, one of the rare companies that still cares about customer satisfaction in today’s market!

Honestly the worst built windows I've ever seen. Buy off the shelf at a box store before ordering from here.
Custom sashes don't fit the frames. HUGE air gaps. Custom casement is full of stripped screws with no structure behind the vinyl. Hinges pulled them right out. The windows have to be pushed closed from the outside.
Less than 12 months since install and 4 or 5 windows are inoperable and needed to be replaced.
Sales rep will get back to you if and when he gets around to it. Expect to have to leave your job early if you need a follow up inspection. They don't don't work past 5pm.
