Proudly serving Winona, MN

Dennis is great. He's helped me with unique projects and is my go to spray guy now. He's the real deal, and has the skills to get it done. Its just nice to talk to a real person on the phone and have that same person show up to do the work.

If you're looking for someone to spray foam your shop, home, shed, ice shack, or whatever, look no further! Dennis was the best person to deal with on my new house/shop build and is super responsive! Couldn't be happier with him, and he lays down some awesome looking foam!

Dennis and his crew did an exceptional job in every way. From communication at the beginning of the job to clean up at the end he was great. He did such a great job that we are going to have him back to do another job for us.

The guys came in and were courteous. And mindful of the things I had in my shop that I could not take down. worked at a fast pace and cleaned up all the mess. I was very pleased with the finished work.

We had a qoute from Schwartz Spray Foam in early spring. Due to some health issues we were unable to move forward with the project. When things settled down I contacted Schwartz Spray Foam and he said it wasn’t a problem. He was able to get our job completed in a timely matter and we are extremely happy with the job. It was very easy to talk to him about our project and what we wanted to accomplish. We would highly recommend!

Highly recommend Schwartz Spray Foam Services! I couldn’t be happier with the work Dennis and Schwartz Spray Foam Services did on our new construction home. After dealing with a lot of different contractors throughout the building process, Dennis was honestly one of the best contractors we’ve worked with. From the beginning, Dennis was extremely professional, knowledgeable, and easy to work with. He took the time to explain everything, answered all of my questions, and clearly takes a lot of pride in the work he does. He didn’t just show up, spray the foam, and leave — he paid attention to the details and made sure everything was done right. The quality of the spray foam installation was excellent. Everything was applied thoroughly and cleanly, and it was obvious that Dennis cared about doing the job correctly rather than just getting it done as quickly as possible. On a new home, insulation is such an important part of the build, so having someone you can trust to do it right means a lot. What impressed me just as much as the actual work was Dennis himself. He was reliable, communicated well, showed up when he said he would, and was genuinely great to deal with. He made the whole process easy and very stress-free, which isn’t something I can say about every contractor we’ve worked with during this build. I would highly recommend Schwartz Spray Foam Services to anyone looking for spray foam insulation. Dennis does excellent work, stands behind what he does, and clearly cares about his customers and the quality of his work. 5 stars without hesitation. We’re extremely happy with the finished product and would absolutely use Schwartz Spray Foam Services again!

Dennis and his co worker did a wonderful job for us with spray foaming! Very friendly and easy to work with. Highly recommended! Always checking the thickness as he sprayed. Very good with covering floors and windows so they didn't get foam on them! Very clean, they left the place so clean after they left and took trash with them! We highly recommend Schwartz Spray Foam!

Nice accommodating expert folks who do their job and go the extra mile without making you feel like you are asking for the moon. Bryce was happy to help me out above and beyond the job and Dennis is a worker who wants nothing more than to fill the need.

These guys are spot on. Dennis spray foamed my pole shed and it looks great. They showed up in a timely manner and knocked it out of the park. If you're looking for this type of service, you can't go wrong with these guys.

Fast friendly service, excellent work. Drove two hours to get to me. Absolutely worth a phone call.

Dennis was prompt and did what was planned. I highly recommend Schwartz Spray Foam for your insulation needs.

I cannot say enough good things about Schwartz! Easy to communicate and work with, punctual, friendly, and detail-oriented. Schwartz sprayed foam insulation in my small tin-roof garage in Wausau, WI. Did a fantastic job. If you are looking to have some spray foam work done, get in touch with Schwartz!

Good job! He got there when he said he would, actually slightly early which was great! We had two different places that needed to be insulated, and one of them was difficult space. And he got the job done! We are very pleased!

Dennis and his team did a fantastic job. Showed up on schedule. Completed the job quickly and on budget. They cleaned up after themselves and the quality of the foam installation was great. Would highly recommend them.

All around great service. From the communication to the job itself. Dennis let us know everything he was doing and kept things easy for us!

Meticulous work & friendly staff

Schwartz Spray Foam Services was excellent to work with. They were very prompt in getting our quote back and went above and beyond to deliver a quality result. Highly recommend!"

I hired Schwartz Spray Foam to insulate the 5000 sq ft of walls in my new shop. They were very responsive to all my questions prior to agreeing to do the work. Once site visit was completed and both parties agreed on the terms the job was scheduled and completed quickly. They payed attention to details and everything was cleaned up post job. Close inspection surprised me as most of my walls have greater than the agreed upon thickness of foam giving me a great value for my investment. I have already spoken to them about my next project and hope we can work together again in the future.

Dennis was great to work with. Sprayed my attic. Communication was outstanding. Punctuality and level of service is second to none. Pricing was ballpark but glad I chose him. Super friendly and a lot of care was taken into account with my house. Treated it as he would his own, which was greatly appreciated. Would 💯% use him again. Schwartz Spray Foam Services will be my first call with future projects.
