WHAT’S INCLUDED

More than an aerosol-sealing appointment.

DAVESDUCTS evaluates the duct system first, identifies major deficiencies and manually seals accessible leakage where appropriate. Aeroseal is then used for qualifying leakage that remains.

01

Pre-Seal Pressure Test

Measure and document the baseline duct leakage before sealing.

02

Whole-System Inspection

Inspect accessible ductwork, including applicable attic and crawlspace areas, and evaluate supply and return conditions.

03

Deficiency Diagnosis

Identify major leaks, disconnections, blockages and physical defects that require conventional repair.

04

Accessible Manual Sealing

Seal accessible qualifying joints and connections with appropriate manual methods such as mastic and metal tape.

05

Aeroseal Procedure

Isolate connected equipment, prepare the system and perform the Aeroseal duct-sealing procedure.

06

Post-Seal Verification

Measure the duct system again and provide the applicable leakage report and certificate.

THE DAVESDUCTS PROCESS

Test. Inspect. Repair. Aeroseal. Verify.

The duct system is evaluated before sealing and measured again afterward.

01

Test

Establish the pre-seal leakage baseline.

02

Inspect

Identify disconnections, blockages and major defects.

03

Repair

Physically correct accessible defects where appropriate.

04

Aeroseal

Seal qualifying smaller leakage throughout the prepared system.

05

Verify

Measure and document the final leakage result.

WHAT AEROSEAL DOES — AND DOESN’T DO

Duct leakage and physical duct defects require different solutions.

Aeroseal is designed for

  • Qualifying leakage at duct seams and joints
  • Small openings throughout the duct system
  • Difficult-to-access leakage
  • Residual leakage after appropriate physical repairs
  • Measured before-and-after duct sealing

Aeroseal does not repair

  • Disconnected, blocked or crushed ducts
  • Major physical openings
  • Gaps larger than approximately 5/8 inch
  • Undersized or poorly designed ductwork
  • Furnace, heat-pump or air-conditioner problems

IMPORTANT

Major deficiencies must be physically repaired.

If testing or inspection identifies disconnections, blockages, large openings or another major physical problem, corrective work may be required before Aeroseal can be completed properly.

10-YEAR LIMITED WARRANTY

Measured sealing backed by written warranty coverage.

DAVESDUCTS includes a 10-year limited warranty on qualifying Aeroseal duct-sealing work, subject to the written warranty terms and exclusions.

DOCUMENTED RESULT

AEROSEAL PRICING FAQ

Common questions before booking.

How much does residential Aeroseal duct sealing cost?

$2,399 + HST for up to 16 supply vents. Additional supply vents are $49 each.

What is included?

Pre-seal testing and reporting, duct inspection, deficiency diagnosis, accessible manual sealing where appropriate, Aeroseal materials and labour, post-seal reporting and certificate, and a 10-year limited warranty.

Can Aeroseal fix disconnected ducts?

No. Disconnected, blocked, crushed or badly damaged ductwork requires physical repair.

How large a gap can Aeroseal seal?

DAVESDUCTS identifies approximately 5/8 inch as the upper limit for a qualifying opening. Larger defects require manual repair.

How do I know it worked?

The duct system is pressure tested before and after sealing so the measured reduction can be documented.

Does Aeroseal fix hot and cold rooms?

It can help when leakage contributes to poor distribution, but undersized ductwork, inadequate returns, restrictions, blockages or equipment problems may require separate corrective work.

Do larger or multi-furnace homes cost more?

Homes over approximately 4,000 square feet, multiple-system homes and other complex properties require individual pricing.
