Windows Installation in Duluth

“Billings did a fabulous job on my roof.
Handled the insurance company with ease.
Very professional crew who went the extra mile to make sure things were done correctly and very clean when they left.
Joe provided me with pictures of the progress while I was out of town which really put my mind at ease.
Excellent communicator!“

“I accidentally popped the top half of a double hung Marvin window out and it landed on a cement driveway. The frame was fine but the glass was shattered. The guys at Glass Guru were able to replace the glass. Everything was great. Thank you very much for the great service“

“George and his team are nothing short of amazing. They made replacing my windshield super convenient for me, by coming to my house today! I appreciate all of their help!“

“We have used BWB twice for remodeling projects - one for finishing/remodeling our walk-up attic and the other for rebuilding a rotting porch/patio overhang. With a 110 year old house, creativity is important and being able to blend old and new. BWB worked with us in meeting our budget, updating and finishing the attic space (with significant improvement in energy efficiency from foam insulation), and then building a new porch overhang to include a stainless grilling counter prep area. They are friendly, high quality, and trustworthy. Bonus points for keeping a clean work area during projects and cleaning up so it looked even better than when they started!Services: Home renovations“

“I am not a very handy person so these guys are my go to for all home repair needs. If they can’t do it, they will point you in the right direction. I have had Scott Didrikson Construction add a bathroom, finish our basement, replace a roof, add insulation to our attic, replace our deck and railings. They have always been very responsive when I have reached out for questions or needs. They have been a great company to work with and appreciate the relationship we have built over the years!Service: Roof installation“

“William gave us a quote for new windows in our house. He is extremely knowledgeable and friendly. He answered all questions we had about the product, company and installation. If you need anything I highly recommend speaking to William!“

“Grumdahl Window and Siding has done two projects at our lake house in northern Minnesota, a large custom window to open up the view of the lake, and replacement of two sliding glass doors. I can't say enough about the responsiveness, attention to detail, and quality of the work that was done. This is a very professional operation, who provide Marvin Infinity windows and doors–the only line of product I was willing to have. The quality of the windows, and installation, are excellent. The advertised "Hi Transparency" screens "for a seamless look," more than live up to their billing. Choose Grumdahl for quality window and siding product and workmanship.“
