What People Are Saying

  • Before we got Vent Cap Systems, I don't know how we survived without them. We have done about 350 duct seals since getting them and they save us atleast 30 minutes per house. That's about 175 hours of labor I didn't have to pay for. They have paid for themselves time and time again. They are easy to use, my guys don't have to carry ladders, and my "tape bill" is almost non-existent. Thanks Corey for making a great product!

  • Vent Caps have cut our costs by as much as 66% on tape - we were generating a lot of tape waste during our verifications. Our tests are as accurate or better than the tape. Vent Caps are quick and easy to use, costs less and provide a professional image that gives our company an edge. We use them and like them.

  • What an awesome product! I'll be honest, I was a little skeptical at first, but once I used it for the first time and got used to it, it was so much easier than taping ducts. Not only does it save time, it saves me from sweating profusely after going up and down a ladder for 45 minutes! Anyways, we just love your product and we hope to order more soon as we continue to grow our business.
