    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. If you're looking for one of the best quality windows that money can buy, lol at the Marvin Infinity line. Fiberglass construction, coastal rated, Low E3.

    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.
