Exterior Vents
Exterior vents play an essential role in your home’s ventilation system, allowing airflow and exhaust from appliances like bathroom fans, dryers, or kitchen range hoods. However, on particularly windy days, some homeowners may notice the vent’s flap making noise as it opens and closes. This is usually caused by strong airflow from outside pushing on the vent flap, which is designed to regulate air movement and prevent backdrafts. While the noise can be annoying, it is often a minor issue that doesn’t affect the vent’s functionality.
Warrantability
Warranty coverage for exterior vents depends on the type of issue:
Alberta New Home Warranty Standards:
- One-Year Workmanship and Materials Coverage: Noisy, improperly installed, or malfunctioning vents caused by defects in installation may qualify for warranty coverage within the first year.
Builder’s Warranty:
- 1-Year Warranty: Builders typically cover improper installation or defective materials related to exterior vents
- Noise or flapping caused by external factors (e.g., wind) or wear and tear over time is not covered.
Manufacturer’s Warranty:
- Vents or venting systems may carry manufacturer warranties covering material defects or mechanical issues. Warranty terms vary but are often between 1-10 years.
- Damage or noise caused by weather or homeowner use is excluded.
Common Issues, Warrantability, and Repair Solutions
1. Flapping Vents
Causes:
- Wind Pressure: Strong gusts of wind may push the flap open, causing repetitive movement and noise.
- Loose Vent Installation: If the vent flaps excessively or makes louder-than-usual noises, the vent may not have been installed securely.
- Weak or Misaligned Flap Mechanism: Over time, wear and tear or incorrect alignment can impact how the flap operates.
Steps to Address Flapping Vents:
Inspect the Vent:
- Check for loose screws or improper installation.
- Look at the flap mechanism to ensure it aligns properly and isn’t stuck or weakened.
Secure the Vent:
- Tighten screws or brackets to ensure the vent is securely attached.
- Test the flap by lightly pushing to confirm proper movement.
Contact Your Builder:
- Within Warranty: If the issue is caused by installation or materials, report it to serviceQ to review warranty coverage and request repairs.
- Outside Warranty: If the issue is unrelated to installation defects, consult a contractor to adjust or replace the vent.
Replace the Vent:
If the flap mechanism is damaged or worn out, install a new vent with wind-resistant features to minimize flapping noises.
