Ecoline Windows

Oleg, his crew and Costco exceeded our expectations for our window and door installation. Measurements were taken 3 or 4 times (by different people), windows fit perfectly, arrived when expected/scheduled, installers were on time, neat, efficient, and polite. Communication was excellent, price was very fair. Windows come with 25 year warranty so we will continue to monitor and hopefully, not need any warranty claims. Thanks Oleg. This was not a small purchase but Oleg and his crew made us feel comfortable with our choice and our investment. We highly recommend them.
