Customer Testimonials

Matt M.

“Nielsen Glass was amazing to work with during our renovation of my great grandmothers old farmhouse built in 1910. We replaced 3 large bay windows, as well as a new double sliding shower door, and George/crew were incredibly professional/clean”
Matthew E.

“We had Nielson Glass come out and give us a quote and ask for their professional opinion about our walk in shower glass and a quote for all the windows and sliders to be replaced. We just love how everything turned out. Very professional, quick at responding to questions and most of all a very clean install. They take real pride in their craftsmanship.”
Rick W.

“I’m a realtor and I needed to get some windows replaced right away. I contacted George and got out to the house, gave us a quick bid and upon our agreement he order the windows. I could not believe have quickly the work got done and how professional he was! High quality work too!”
