Why did the technician leave wet carpet on my stairs during the water restoration?

If carpet is left on the stairs, it is more than likely unsalvageable, and it will be removed when new carpet is installed. Carpet on the stairs is generally not removed for safety reasons. Exposed tack strips or staples is dangerous. However, there are situations where removing carpet from stairs is necessary to prevent damage to hardwood steps or because of sewage contamination. Removing tack strips is not advised, as this may damage floor or subfloor. Extreme caution must be used when tack strips are exposed.
