It's not the first time this has happened,,,, BELOW - HRV Intake. BELOW - Laundry dryer exhaust. I wonder if the venting and exhaust systems in all of the other new Mattamy Oakville town homes on this block are just as bad as this 30 day old home. In this case, and likely at the other homes, it looks like some unskilled worker simply glued / caulked the white vents over holes without making any attempt to ensure that the venting systems will actually ever work properly. Oh well, fortunately for MY customer these issues and others were identified during a 30 day warranty inspection and now that he understands the problems, he has every right to insist that the builder fix them properly. As well, my client can also reference the detailed online PDF inspection report that I sent to him with additional photos and code references.
1 - the dryer duct is not connected to the white vent and it appears that about 15 feet down the duct that it is disconnected.
2 - the laundry room exhaust fan duct is behind the vent but not connected to the vent.
3 - the HRV exhaust duct is not connected to the vent so it is simply venting into the structure.
4 - the first floor bathroom fan exhaust duct is missing the required screen, blocked with some house wrap, and the duct is not connected to the vent.
5 - the HRV Intake vent has the wrong flaps making it impossible for the HRV to suck in fresh air, it's missing the required screen, and the intake duct is behind the vent but not even close to being connected to the vent.
In other words. This homes venting systems are a complete fake and it is impossible that the person who installed the white vents did not know that none of these systems would work properly. My conclusion is that they did not care.
