Vince and Sofie were very knowledgeable about the windows. I really enjoyed their presentations. They were really good at what they did.

I couldn't be more satisfied with my choice of window, Marvin Infinity, and the perfect installation performed by the crew at Les Grumdahl Window & Siding.

We had 12 very large windows replaced and Les Grumdahl and his team did an exceptional job. There was absolutely no damage to the landscape (a very challenging site) or to the interior. They even were able to thread the needle in our garden to set up a lift. 100% satisfied...and we're very particular customers.
