Another Spray Foam Nightmare?
Sorry to share another potential spray foam horror story, but I’m hoping ya’ll who have seen a lot of this can put in your two cents.
We are working on our old attic in Washington DC. Just had vermiculite removed from the floor, and then 4 inches of closed cell foam applied to the roof and gable walls. The rafters are 6 inches deep. The contractor has stated that they used Natural Polymers brand closed cell foam, and sent over this product info:
The guys spraying failed to use proper ventilation during application, despite my repeated questioning of them and the company office. They assured me that 24 hours with the windows open and bath fans running would be plenty of time to remove the foam odor. Of course it wasn’t. When the smell was still overwhelming after 48 hours out of the house, I got the company to set up an exhaust fan. It ran for 1 full day on the main level, then we moved it up to the second floor, and finally at my suggestion they placed it directly in the attic and opened up the duct at the gable vent to allow fresh air to come in.
The fan has been running for 72 hours, and the smell has definitely improved. The manufacturer says the contractor made a major mistake not following their ventilation guidance, but as long as the foam is of good quality, post work ventilation should address the problem, and they’d expect the smell to be unnoticeable after a week. The contractor claims it doesn’t seem strong to them anymore, but they have left the fan running and have offered to cover our rental costs while we remain out of the house 4 or 5 days longer than expected.
I’d like to find a third party who specializes in inspecting this work who can help me get a grasp on whether ventilation was the only mistake, or if there are underlying problems with the foam. I’m probably overreacting, but I’ve got an infant who has to sleep right below this stuff, so I’m not sure I’ll even be fully satisfied just by the smell greatly decreasing.
I’ve attached some pictures, perhaps ya’ll can assess the work from afar and let me know if you see areas I should be digging into. It appears quite uneven to me, and I don’t know if the variance in textures I’m seeing could mean errors in the mixing/ application process that will have long term toxic impacts. Also if anybody knows of a company/individual in the area who could inspect this work, I’d appreciate the recommendation.
Thanks in advance,
