Opening & closing in Dennis

What the job involves

Spring openings and fall winterizing for pools and spas, booked early so you are swimming on Memorial Day.

Openings fill up fast in April and May, so we take bookings early and give you a date. At the opening the cover comes off, the equipment starts and we bring the water back. In the fall we blow out the lines so the plumbing survives the Cape winter, treat the water and close everything up tight.

About Dennis

Dennis stretches from the Nantucket Sound beaches of Dennis Port to the bay side of Dennis village, with Bass River on its western edge. Many lots are compact, so a pool here is often about fitting the right size and shape between the house, the septic system and the property line.

Robert Kazarian

Just finished our beautiful gunite pool and travertine deck. I’ve worked with many contractors, and Clearwater was among the very best in every respect. High quality, flexible and very responsive. Longest I ever waited for a return call was about 2 minutes. Everything was on schedule and pricing was fair. Rod and Clearwater also have great subs for landscaping, stonework and other things you might need. I highly recommend Clearwater for your pool construction and maintenance.
