Whole Home Weatherization

June 24, 2026 Trevor, with DBS foundation, base and insulation, just completed work on my Madeline Island Cottage on Lake Superior. The work, included Excavation, shoring and replacement supports in the Crawl Space of this 1940 Lake home. I was pleased with the technology at DBS uses, and the knowledge and technical proficiency that Trevor had in doing the work. He was thorough, and listen ed carefully to my concerns. I was absolutely 100% satisfied with his work and that of his assistant Corbin. If you are in need of foundation repair in Minnesota and Wisconsin, I highly recommend DBS. Donald W Laukka, architect.

Nick and Rob from DBS stopped out to do some warranty repairs last week, specifically to spray some foam insulation in just a few areas that were missed in the original crawlspace encapsulation. They did a great job; quick and clean work. I'm quite pleased.

Thank you so very much for insulating our basement and stabilizing our basement floor. Jake did a great job of explaining what needed to be done and Westin completed the work. We are very pleased with the work done and how well they kept us informed of the project. We highly recommend DBS.

Icicles! Up and down our eaves when no one else in the neighborhood had them! We called DBS and Myke came out to do an inspection. He helped us clearly understand our problem--very old insulation and hardly any baffles--and outline our solution. Joe and Griffin did a great job with the repair! They were extremely courteous and careful in our home; and so easy to work with. I had no idea that insulation needed to be replaced, but now we aren't dreading the next cold days...as much!

We had Bryan out to perform an inspection of our attic for a few issues we were encountering. Bryan was prompt and on time. He called the day prior to the appointment to confirm the time. He inspected our insulation and attic and helped us identify another problem as well. Kudos to Bryan for being professional and personable. I would recommend Bryan to anyone looking for home inspection and repairs.

Overall great experience. They did a fantastic job of explaining all of the work. Added the different kinds of insulation in very tight areas. And the clean up was superb. Would highly recommend DBS.

It started with a busted water pipe, 200 gal of water in my basement, leading to a new found hole in my basement wall & other surprises. I researched, cried some, researched more, made calls, had a couple different companies come out. Honestly? The 1st phone conversation with Bonnie Sundberg's DBS Foundations, Basements & Insulation I had? Gave me a much needed breath of relief. The compassion & reassurance meant everything. Bo Meintz was my Specialist. He took time to answer the most outside of the box questions & concerns. And trust me, after 200 gallons of water? You question A LOT. I am thankful for Bo and his patience. His knowledge and explanations , superb! Thank you!

I had a great experience with DBS. Scheduling of the energy inspection was simple and fast. The Design Specialist, Justin, conducted a thorough energy audit. Justin was very knowledgeable, explained things at my level, and he provided all of his recommendations without at all being pushy. He communicated via text and email and responses were always timely. The cost of the insulation installation seemed to be comparable to competitors. The job was completed in a few hours and the crew cleaned the area well. I’d definitely use DBS again and would highly recommend Justin.

The DBs team came out this week to re-insulate the Patrick of our home and added insulation to our garage that never had any blown in. The crew worked very hard and cleaned up after they were done. I highly recommend their staff to help anyone with their home. I would recommend not waiting 29 years like we did.
