Duct Repair in Coquitlam

Signs Your Ductwork May Need Repair

Duct problems aren’t always visible, but they leave clues. If any of these sound familiar, it’s worth having your system looked at before things get worse.

• Uneven room temperatures: Rooms that are consistently too hot or too cold often point to disconnected sections or significant air leaks in the duct network.
• Dust accumulating quickly: If your filters need changing more often than usual, deteriorated or poorly sealed ducts may be pulling in debris from crawlspaces or attics.
• Rising energy costs: Unexplained increases in heating or cooling bills without a change in usage can indicate conditioned air escaping through leaks.
• Musty odors near vents: Moisture infiltration through damaged or unsealed ducts can lead to mold growth, a particular concern in the damp Lower Mainland climate.
• Visible damage: Disconnected sections, crushed flexible duct, gaps at duct joints, or collapsed runs are direct signs that repair is needed.
• Unusual sounds: Rattling, whistling, or rushing air during operation can indicate sections that have come loose.
• Older duct systems: Systems more than 20 to 25 years old are more likely to show joint failure, insulation breakdown, and general deterioration.

What Duct Repair Covers

Duct repair restores your existing system rather than replacing it. When the overall structure is sound and the damage is localized, repair is generally faster, less disruptive, and more cost-effective than a full replacement. We use camera inspection during the assessment to find damage inside the duct that isn’t visible from outside.

The types of repair work we perform across Coquitlam residential and commercial properties:

• Duct sealing: Leaks at joints, connections, and seams are sealed using mastic sealant or approved sealing tape, which can help reduce conditioned air loss at the source.
• Section reconnection: Disconnected duct sections are reconnected and secured, which can help restore airflow to rooms that have lost supply.
• Flexible duct repair: Damaged flexible duct in crawlspaces and attics can be patched or replaced as a section without touching the rest of the system.
• Insulation repair: Duct insulation around runs through unconditioned spaces is restored, helping with both energy efficiency and moisture control.
• Duct joint repair: Failed or separating joints are refastened and sealed to help prevent air leakage and debris infiltration.
