We hired Semko this fall for a total building window replacement project, almost 300 windows. This was a major job, 100 year old building, with big windows! Over the course of 3 weeks the Semko crews organized and completed the job. I can't say enough good things about the experience. 2 months later I'm happy to say we absolutely hired the best company for the job got the best deal and 24 out of 24 owners have commented they are 100% satisfied with the finished product. Big thanks to Jason and Adam.

We are very happy with our new Windows! Our new place is warmer and definitely energy efficient. Semko, too out our old aluminum frame windows and replaced them with energy efficient pvc ones. I highly recommend Semko if you are looking to get new Windows. They were helpful, friendly and efficient in every step of the way.   Thanks!!!!
