We’ve used Wind Load Solutions for a while now, and we would recommend this program quite readily. We’ve tried other programs in the past, and they were complicated to use, almost cumbersome. They give you all the necessary tools and reference links to get the job completed. Also, I can’t say enough about Greg’s helpfulness and knowledge of the entire operation.
We use the wind load solutions calculator daily at our firm. We love it because it’s user friendly and accurate. We use the software exclusively for all of our wind pressure design needs for over 3 years now and have successfully permitted hundreds of projects using it.
More real testimonials coming. We’re recovering 20+ years of customer feedback lost in our 2025 site rebuild. New testimonials are added here as each customer grants written permission to republish.
