Ductwork pricing varies enormously based on whether you need sealing, partial repair, or full replacement. A $500 sealing job and an $8,000 full duct replacement are both "ductwork." Here is what each scope actually costs in Oklahoma.

Detailed Pricing Breakdown

Service / PartCost Range
Spot sealing (2-3 problem joints)
Mastic sealing of identified leaky joints. Quickest fix.		$500-$900
Full system sealing (all joints)
Pressure-test the system, identify all leaks, mastic-seal everything. Major efficiency improvement.		$1,500-$3,000
Aeroseal (interior coating)
Specialized aerosol that seals from inside. Effective for systems with leaks behind walls or in inaccessible places.		$2,000-$4,500
Add new return duct
Improves airflow on systems with insufficient return.		$400-$900
Repair/replace one duct run (10-20 ft)
Single damaged or inadequate run.		$300-$800
Replace flex duct in attic (full)
Common for older homes with deteriorated flex.		$1,800-$3,500
Full ductwork replacement (typical home)
Complete tear-out and replacement with new metal trunks and modern flex branches.		$5,000-$8,000
Insulation upgrade (R-8 wrap)
Wrap exposed attic ducts. Reduces conditioning loss to attic.		$600-$1,500

All prices are for the OKC metro area. Actual quote may vary based on your specific situation.

What Pushes Cost Up

  • Larger homes with longer duct runs
  • Difficult access (tight crawlspaces, low attics)
  • Concurrent insulation work
  • Removing asbestos-wrapped ducts (older homes)
  • Custom sheet metal fabrication

What Lowers Cost

  • Single-issue spot sealing
  • Easy attic or basement access
  • Standard flex duct work (vs custom metal)
  • Combined with HVAC equipment install (lower labor markup)

Frequently Asked Questions

How do I know if I need ductwork repair?
Signs include: uneven room temperatures, high energy bills despite new equipment, excessive dust, hot attic spaces above normal, and rooms that never reach setpoint. A blower-door test can quantify duct leakage precisely.
What's the difference between mastic and Aeroseal?
Mastic is applied by hand to visible joints. Aeroseal is an aerosol injected from inside the ducts that seals leaks invisibly. Aeroseal costs more but works where ducts are inaccessible (behind walls, in tight attics).
How much energy does leaky ductwork waste?
Typical residential duct systems leak 20-30% of conditioned air into unconditioned spaces (attics, crawlspaces). Sealing can recover 15-25% on utility bills and is often the single highest-ROI HVAC improvement you can make.
Can ductwork be sealed from inside without replacement?
Yes — Aeroseal works from inside for leaks that can't be easily accessed. For leaks visible in attics or crawlspaces, external mastic sealing is typically more cost-effective.
How long does duct sealing take?
Spot sealing: 2-4 hours. Full mastic sealing: 1 day. Aeroseal: 1 day including setup, injection, and cleanup. Full duct replacement: 2-3 days.
