"Working with Vortex was a great experience. The crew was totally professional and very experienced and did an excellent job spraying closed cell insulation in the new addition to our house. When they were done the job site was left totally spotless. Their prices are very reasonable/competitive. We are very pleased with the work they did and how easy it was to work with them. We will certainly use them again in the future."
