“I’ll never wash my windows again. For me, it’s a never-ending project like painting the Golden Gate Bridge, but for Sid it takes a morning and leaves the windows looking crystal clear. They didn’t look that good the day they were installed.”

Jane T, Music Instructor


Dear Sid,

Thank you so very much for the incredible job. I loved coming home to see such sparkling panes. I was anxious for my party to begin and the guests noticed, too. Thanks again.



Hi Sid,

The windows have never looked better. Thank you!

Sid Graef (Spectrum, Inc.) is one of the best “service” people I’ve had the pleasure to work with in Missoula. He makes every effort to deliver a flawless job in a timely manner. Customer service is his primary goal and he has never failed to deliver! And on top of it all, he is very easy to work with and very comfortable to be around and have in your home. I call him trustworthy, reliable and a very nice person!

Even after the rain the house window’s sparkle. It truly is a delight. Thank you so much for your loving care for our belongings while shining up the windows.
