Eliminate Conditioned Air Loss and Hot/Cold Room Imbalances

Frequently Asked Questions
Common questions about duct repair & sealing in Manchester, NH.
Duct Repair & Sealing Manchester, NH
The Invisible Drain of Leaky Sheet Metal and Crushed Flex Ducts
In many older or poorly remodeled homes, duct joints were sealed with basic cloth tape that dries out, deteriorates, and peels away over time. Furthermore, uninsulated supply runs traveling through unconditioned attics lose heat rapidly in the winter, causing air to arrive at your registers lukewarm rather than hot. Our team repairs collapsed flex ducting, reconnects loose take-offs, wraps bare metal in high-R-value duct insulation, and applies commercial-grade mastic sealant for an airtight bond that lasts decades.
