No, but some pool owners that own the required equipment do in fact close their pools themselves. It is a matter of having the proper equipment (blowers, compressors & misc. tools), proper KNOW-HOW, and time. If one makes a mistake “opening” a pool it is usually a simple repair by a knowledgeable technician. If one makes a mistake winterizing a pool, it can be a very significant problem if it is due to not getting the water out of the lines (underground plumbing, heaters, pumps) and can be costly. Most of our customers hire pool professionals (our service department is here to help) to perform this very important service. It is not something one should do without being very well prepared.
