See What Our Customers Are Saying
We’re very satisfied with our Calhoun building. The HSS post option was one of the main considerations that helped us make our decision. From the initial site visit to the building and completion of the structure, we were impressed with the National Building Group, their crew, and overall professionalism.

Martien Kusters

DutchDeltaFarms Ltd., Sarnia, ON

"(Calhoun), Greg Lussier, and their team performed a miracle by putting up this amazing indoor riding arena structure in the 10-day time period I was gone. I can not tell you how thrilled I am with this arena . . . instead of dreading another winter, I am now planning all the fun my horse buddies and I will have!"

Sandy Bender

Vermont

"The building looks great both structurally and aesthetically. The crew did a great job putting the building up fast while maintaining high quality workmanship."

Joe Wisinski

County Highway Superintendent; Madison County, New York

"I am pleased by the friendliness and hard work of the crew, and ability to keep on schedule with the construction. Something that is quite rare nowadays. I would recommend Calhoun to anyone wishing to put up a large area under cover, quickly and efficiently, at a minimum cost."

J&B's Split Rock Farm

Weathersfield, Vermont

"We are very impressed with the quality of our Calhoun product, and the method employed to make the construction a pleasant and rewarding experience. Our structure was delivered in the time frame quoted, construction commenced on the promised schedule, and was completed with the utmost of efficiency and professionalism. Staff is highly competent, polite, and demonstrated concern for everything being exact."

Debra Anderson

Gaited Stables; Brandon, Vermont

“[I am] 200% happy with the customer service the Calhoun dealer, Hybrid Building Solutions, provided before, during and after the building was constructed. We looked at other solutions, but with the quick turnaround and recommendations from other government connections, in addition to the extra service and inspections, it was a win-win situation.”

Highway Superintendent

Town of Hermon; Hermon, New York

“We have a sound building with sufficient storage and the speed we need to keep up with the needs of our farmer-customers. Kudos to Greystone (and Calhoun) for making that happen.”

Lane Mielke

Area Operations Manager; Pinnacle Agriculture, South Dakota

"We have two Calhoun Super Structures on our farm and plan to build a third this year. The natural light and fresh air flow provide a superior environment for the animals. We used to raise our young stock in the old milking barn. Over the course of a winter, we would usually have a handful of illness cases. Now we raise them in our 40 x 90 Calhoun structure and this past winter, not one case of illness. These buildings are top notch."

Nick Meyer

North Hardwick Dairy; Hardwick, Vermont

"I can only recommend Calhoun to anybody who wants an indoor arena or any other type of Calhoun superstructure for that matter. The lighting is perfect, the high ceiling gives us lots of space, we don't feel crushed, and the opening rolling fabric spaces on the long sides of the arena make us feel outside during the summer months - it is perfect! The quality, the service, and the craftsmanship are just top of the line. Thank you so much Calhoun for making such a high-quality product!"

Michele Poitras

Quebec

"I have seen neighbours’ structures with wind damage and our (Calhoun) arena has withstood some pretty strong wind gusts."

On the Forest Boarding; Stouffville, Ontario
