Duct Sealing Serving Kings Isle — Aeroseal & Mastic
Duct leakage in Kings Isle homes can waste 20-30% of your cooling before it reaches a register. We run a CFM25 pressure test before we touch anything, seal the leaks with mastic or Aeroseal where appropriate, then retest and show you the numbers.

Common questions from Kings Isle homeowners
How much duct leakage is normal in Kings Isle?
Energy Star target is under 4 CFM25 per 100 sq ft. Most pre-2005 homes test at 3-5x that. Post-seal we're usually back to target.
Aeroseal or mastic?
Depends on access. Exposed attic runs: mastic. Inaccessible chases or wall cavities: Aeroseal. Often both on the same job.
Will I actually see a utility bill difference?
If your test shows 20%+ leakage, yes — typically 8-15% summer savings. If leakage is low already, the ROI isn't there and we'll say so.
