Stillwater & Twin Cities General Contractor

“Really surprised by the effectiveness of this treatment! The application was very quick and my roof almost immediately looked like new again. Thanks to the Gonano team!”

“I live in the rust belt and it lives up to its name: here everything rusts, cracks and breaks. I had the treatment applied to my concrete steps and the concrete slab at the back of my townhouse. I hope it will protect them from the salt and make them last longer. So far, no cracks. It really seems to repel water, which is a good thing!”

“The 15-year-old membrane on our workshop was beginning to lose its granules and crack. So we thought we didn't have much to lose by trying Gonano. The result is incredible. It is as if it had turned new again!”

“I have a 300 foot wooden fence around my back yard which is constantly attacked by the sun's rays. I have to replace a few boards every year because they dry out and twist. No wood stain lasts more than 3 years. I had Gonano applied, telling myself that it couldn't hurt. I am surprised! I had a lot fewer boards to change this year and the wood stayed darker, it still looked like new!”

“I was hesitant to pay for Gonano because it was new and I couldn't believe it worked so well. Well, it's been two years and I can say it exceeds my expectations! I find a lot less granules in my gutters and my shingles seem to have stopped aging! Can't wait to see a Gonano treatment for siding!”

“I was going about redoing the roof on my warehouse as the membrane was really damaged by the sun. The sun is our worst enemy here. lol! Gonano seems to have given my roof a good face lift. I can't wait to see the result in 5 or 10 years, so far so good!”

“I had the treatment applied to the decorative wooden elements on my house. The goal was to protect them from the sun but I wanted to keep the natural look of the wood. I also liked the fact that it is eco-friendly. 2 years later, my wood hasn't moved, it still looks like new!”
