What customers say

Customers generally view the BUTTERFLY CAP-DAMPER as a highly effective solution for improving chimney efficiency and preventing unwanted drafts. The primary praise centers on its robust sealing capability, which significantly reduces heat loss during the off-season and successfully blocks pests and rain. Many users report immediate and noticeable improvements in home comfort and reduced energy bills, validating the product's value proposition. Installation is frequently cited as manageable, especially for those comfortable on a roof, though some reviewers noted that the cable routing and securing mechanism required patience and careful adjustment to ensure smooth operation from the fireplace below. The main area of concern revolves around long-term durability, specifically the integrity of the operating cable and the damper's hinge mechanism under continuous exposure to harsh weather and soot. While the stainless steel construction is generally appreciated for its resistance to rust, a small segment of users experienced issues with the cable fraying or the damper sticking after several seasons of use, suggesting that periodic maintenance is crucial. Despite these minor mechanical caveats, the overwhelming consensus is that the BUTTERFLY CAP-DAMPER is a superior alternative to traditional throat dampers, offering excellent performance and sealing power, making it a highly recommended upgrade for homeowners seeking better draft control and substantial energy savings.
