We're restoring a fire-damaged house and hired a subcontractor to do smoke remediation, after we'd stripped the house down to the studs.
The contractor was supposed to soda-blast all surfaces, clean, and then apply smoke seal.
The contractor claims to have finished the job, but the smoke seal has been applied right over: cobwebs, bits of stray insulation, loose dirt, and even wasps' nests!
This suggests that the blasting was not done but, of course, the contractor swears that it was.
Is there any way to tell for sure? (Maybe they just missed a few -- okay a lot of spots.)
