Duct Sealing is Included!
When you purchase a Sealed Crawlspace or Attic Air-Sealing or the Bonus Room Comfort Solution from Stetten Home Services you also get “Duct-Sealing” in the affected area. We will seal any accessible leak we can find!
We generally use expanding foam and tape and silicone caulking for duct sealing but certain circumstances call for using “Bucket Mastic” which is applied with a paint-brush, and the brush works pretty much like a spatula. As the product dries, the fibers in the mastic create a strong material similar to what people use to set tile. While that strength is good it doesn’t also add any R-Value. Many of our projects are single day projects, and mastic takes so long to dry that you can’t come back in 20 minutes and re-insulate or re-fit the insulation. For this reason, we often choose foam, because it seals, insulates, and once it is dry it adds a little strength to the joint. Sometimes a combination of tape and foam is the best for loose duct connections. If needed we add screws for even more stability.
