Failed Rim Joist Insulation Job
I recently had a contractor install foam rim joist installation in my basement. They indicated the foam would be 2 to 3 inches thick. It appears the foam was not properly installed as it seems to be only about 0.75 inches thick over most of the joist and has puddled at the bottom. The installer also indicated that after installation the foam was spray ‘painted.’ Based on what we felt was the failure of the contractor to deliver the promised specs for the job, we withheld a significant portion of the payment for the work and requested that the manager of the company come and inspect the job with us.
I have a couple of questions. First, is this a failed job and if so what caused the failure? Second, is it realistic to think this job can be fixed by the addition of more foam as the installer suggested at the time? My concern is with the layer of ‘paint’ will the additional foam actually adhere? How can we confirm this would actually be the case? I don’t want to pay them for the complete job if it’s really not going to deliver the performance we should be getting.
