Customer Greenhouse Testimonials
See what our lifelong clients are saying about Wisconsin Greenhouse Company.
“I couldn’t wait to have our greenhouse installed. It’s the perfect addition to our backyard and the crown jewel of our garden. And, I can start my seeds two months earlier.” — Kenneth D.
“The structural integrity on this greenhouse is nothing short of miraculous. I returned from an out-of-state vacation to find that 14” of snow had fallen – the load-bearing roof didn’t flinch. Not only that, but being able to tend to and appreciate my plants in the middle of a Wisconsin winter is a godsend.” — Evan J.
“I love to hide from my husband in our new home-attached greenhouse. I typically bring along a book and a big glass of wine – sometimes I even let him come with me.” — Deborah P.
