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