Ductwork Repair, Replacement & Sealing

Aging duct networks across older housing stock in the North End, Proctor District, and Stadium District often lose up to 30 percent of conditioned air through degraded cloth tape, loose elbow connections, and uninsulated metal trunks. When warm air escapes into damp dirt basements or unconditioned attics, central forced-air furnaces and heat pumps run continuous cycles without reaching the thermostat setpoint. Addressing disconnected plenums or torn flexible runs immediately restores static pressure, delivering balanced airflow to cold top-floor bedrooms and perimeter living spaces.

Local architectural conditions along the West Slope and South Tacoma require specific material choices to handle seasonal humidity and moisture intrusion. Uninsulated sheet metal running through ventilated crawlspaces creates condensation during humid shoulder seasons, which accelerates joint degradation and compromises indoor air quality. Applying professional-grade mastic sealant, foil-faced tape, and external fiberglass duct wrap halts thermal loss and keeps damp subterranean air from being pulled into the living quarters.

For major home remodels in Hilltop, the Lincoln District, or Fern Hill, full duct replacement provides a superior alternative to patching severely crushed, undersized, or rodent-compromised duct lines. Installing properly sized rigid metal supply trunks and smooth-radius takeoff fittings reduces static resistance, allowing modern high-efficiency heat pumps to operate at their designed output without straining the blower motor.
