Les Grumdahl Window & Siding provides complete in-house sales and installation for most exterior aspects of your home repairs and upgrades in Duluth, MN.
They installed 12 Marvin Infinity replacement windows in our house, most of the windows. They did a good job and finished in less than a week, working every business day. The person who did the estimate (Tim) and the workers were friendly and courteous. They cleaned up well after themselves both inside and outside. The only issue we had is their timeline for starting the job, ours started months later than originally stated. My suggestion to Les Grumdahl employees is to over-estimate the time to start rather than under-estimating. Customers will be more happy if you show up earlier than expected rather than later.

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.

Les has given my relative the run around for MONTHS trying to get him to fix their awful work. His customer service is no better. Too bad you can't give one star. AVOID!

Our house is 100 years old and has 4 levels.We replaced 25 year old windows on our upstairs level.We noticed just hours after installation that it was significantly warmer and no drafts were coming down the stairs. We couldn’t be happier! Window replacement does help immensely! The crew was professional and friendly. Great looking windows, great local company and I highly recommend them.
