"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."

"Bill Millis did an excellent job removing our original windows and installing new Pella windows. He also worked hard to allow us to keep our existing aluminum siding, which was no longer available. I have provided his contact information to several neighbors and friends."
