The experience I had with Retro Green was awesome. I had a lot of questions about the process and they were very knowledgeable and patient. Thanks Drew and Don!! Great guys that came out to do the install and they cleaned up very well. I have noticed a difference already in my lake cabin. Thanks again Retro Green.

I had expanding foam insulation installed in the walls of my 1954 house by RetroGreen of St. Cloud. (Although the blown in attic insulation I had hired 5 years prior helped utility costs tremendously, the old wall batting was making little difference in heat retention.Or keeping cool.The new furnace ran often.)
A great 3 man crew arrived on time; they were polite, got along well, worked efficiently, and clean up was like " they had never been there." My foundation plants survived very well and were treated with care.

The double dutch lap siding was handled expertly.
Exterior sound from the neighborhood was reduced immediately. There's little doubt in my mind that propane and electricity usage will be reduced. It feels even more of a sweet, cozy little house now. You have a great crew , Chris. Thank you for the thorough coverage of information and quote early on.I appreciate the immediate rebate application form being taken care of,too, Lupe.

Highly, highly recommend! From the thorough assessment of needs, to the clear estimation (broken into priority levels), to the exacting completion of the job, to the positivity, friendliness, and cleanliness of the work crew, to the completed project we have been extremely pleased! Already notice a difference particularly in the upstairs but also throughout the house. Excellent experience!

These guys were great. Sales/quote was very thorough and informative, good communication and follow-through on rebate applications. As for install, the crew of 4 or 5 worked well together, showed up on time, answered my questions, knocked out my retrofoam install in 6 or 7 hours, did a respectable job cleaning up afterward, and I can't even tell which pieces of siding they removed. Good work fellas!

Great crew - great work! Professional and reliable from bid to finished job. I had a really rough start trying to find a local company that would show up to look and actually provide straight answers and a solid bid. It was overwhelming and stressful. From the moment Retrogreen took my first phone call, the stress was gone. The crew was great, my house is finally cozy. From their general expertise, to the excellent customer service and fantastic work, I cannot recommend this company enough.

The crews arrived right at the time expected, went right to work and everyone seemed to know just what their job was. Worked very well together and were very courteous and concerned whether or not I had any questions about the process. The job went very well and when they were finished, everything was cleaned up just like they had never been there. I am sure when winter comes we will notice a big difference in the warmth of our 100+ year old house.

The crew did great job! Once the project was complete what difference did it make! I would recommend Retrogreen Energy to anyone especially with older homes that have no insulation in the structure from roof to basement walls!

Retrogreen insulated my older cabin. They were really fast, they made sure the foam didn't get inside and make a mess, and they cleaned everything up when done. I was very impressed. Special thanks to Nick, Nate, Scott and Lupe. Also, the foam seemed to make a difference right away. The place stays warmer when its cold out.

For insulating my old home's attic they were careful, thorough, cleaned up after the work was done, and finished everything in one day.

RetroGreen was great to work with! After coming to them with concerns about temperature fluctuations in our 2nd floor, they were quickly able to identify the problem (literally no insulation), and come back with a quote. They were able to fit us in quickly after receiving the down payment and clearly laid out all the tax and rebates available to us. Were very happy with the work and are excited to not freeze this winter!

From start to finish, the RetroGreen team was great to work with. Quality people, quality communication, and quality service with very little disruption to our 100 year old house.

RetroGreen Energy is the best! 5 STARS is NOT ENOUGH! We are so grateful for RetroGreen's commitment to excellent work, and to treating us with respect. That started from the very first moment Don arrived for our estimate, and never stopped. He was knowledgable, thoughtful, and responsive even after we had made our final payment. The crew was professional, courteous, and businesslike throughout.

When we noticed a minor oversight, and brought it to their attention, in less than an hour we heard from a member of the team who scheduled a time to come out and make things right. And that's just what they did. They even helped us with energy rebates that made it possible for us to afford this attic and sunroom insulation project. We say again: 5 STARS is NOT ENOUGH!

The guys showed up almost a month early (thank you Minnesota winter) at the appointment time and were ready to work within a short time. Very professional crew. Explained everything, didn't;t mind me watching over their shoulder, and when they left you couldn't't tell they had even been here. Now to wait and see what the difference in sound and heating/cooling bills will be.

RetroGreen did a nice job insulating my attic with spray foam. Both the sales team and installation team were easy to work with. I would definitely hire them again.

Great experience and extremely professional crew! They insulated the attic spaces in our 1 1/2 story house. This reduced our air leakage by 38% Seriously! Executed a combination of foams and blown fill exactly as planned, arrived and completed on schedule, and kept everything extremely clean! Even sent me pictures of the final installation for my records! I wish all my contractors were this professional!

Everyone associated with this project was professional and pleasant from the owner who provided the initial overview and quote to the crew who worked in the hottest weather of the summer to complete my project on time. It was a sizable investment in my 1949 home. I immediately noticed the reduction in outside noise and an improvement on what was a drastic difference in temperatures between main level and second story.

Excellent Service.
Chris had a large crew doing our attic crawl space. Several trucks and lots of equipment. They had to open up the roof to access this tight space. The crew removed the old crappy insulation, foamed in new for R-60, repaired the roof with matching shingles. They where finishing up as the rain came. Excellent timing guys. I am glad the team was so well prepared and did good job of cleaning up. We can feel the difference in our home already.

The retro green guys did a spectacular job insulating our almost 100 year old house. Super professional and made the whole process super easy. Highly recommend if youre looking to have your house insulated!

I couldnt be happier. By far the most knowledgeable and professional salesperson and installers of any that quoted me. I see why they have such a great reputation in the industry. I would 100% recommend them for any of your insulation needs.

The team at Retro Green did a fantastic job on our house. They showed up when they said they would, left our place clean, were very responsive and professional. We would highly recommend!
