"Great windows at a fair price and Steve does terrific work. Everything was done meticulously, on time and cleaned up like the job never happened. I won't be calling or recommending anyone else for window replacement."

"We purchased Wasco Windows for our entire house many years ago. We recently had warranty repair on 2 windows. Steve was on time for the appointment and ready to work. He fixed both spring issues right away. He commented that the windows still look great...which I agree with."

"Excellent. They showed up when advertised, went about their business quietly, did an excellent job of cleaning up, carted all the old windows away, and left us with sparkling clean, high quality new windows. No more windows rattling in the wind to keep us awake. These are not the cheapest windows around but their quality is outstanding."

"Brian and Kurt were great. We had our 30 + year old Anderson windows removed and replaced with new glass. This is much less expensive than a full window replacement, and is possible when the basic window frame is still in good condition. Super happy with the result."

"We had two windows replaced and they look great. We had old, outdated, drafty windows, and now we have beautiful, secure, functional and high quality windows that have kept in the warmth this winter! The windows that we ended up getting have features that we didn't have before and we love it all - the ability to move the screen up and down, easy tilting options to make cleaning the windows so easy, locking mechanisms, etc. The ordering process was easy, and staff were friendly."

"Window install went well. Main problem was we wanted an additional window installed and this company will only replace windows not install new ones (However small, simple or straightforward the install)."

"Met with Alec about 3 windows. He was so enthused and confident about the windows his company sells, we agreed to go with them. Price was good, time out for delivery seemed good. Alec was very easy to work with, explained everything we needed to know. Thanks and can't wait for the windows."
