The actual work
Most homes have leaky ducts losing 20-30% of conditioned air to attics and crawl spaces. Sealing the duct system is the highest-ROI HVAC improvement most homeowners can make.
We test ducts with a blower door + duct blaster, identify leaks, and seal them with mastic (better than tape long-term) or aeroseal injection.
Full duct replacement is rare — only on systems with collapsed flex-duct, severe pest damage, or major redesign needs. More common: targeted replacement of damaged sections plus sealing of the rest.
Price expectations
Duct leak test (blower door + duct blaster) runs $350 – $560. Mastic duct sealing (whole house) runs $1,060 – $2,250. Aeroseal injection runs $1,750 – $3,500. Damaged duct section replacement runs $425 – $1,500. Full duct system redesign + replace runs $4,250 – $12,250.
Local context for Oakland
We dispatch from a shop near the city limits, so Oakland runs are quick. Suburbs and outlying towns run longer.
Most of our Oakland ductwork cleaning, sealing & repair jobs come from older neighborhoods, where the housing stock just has more failure points.
