Pool Closings

Pool Closings

The most critical aspect of pool maintenance is a proper pool Closing, to ensure that all equipment and underground lines are properly purged of water and shut down for the cold Winter months. Pooltek crews are trained to handle all aspects of pool closing for you, so everything will be properly Winterized.


Includes Backwashing filter, Rinsing DE and Cartridge filters with water, Lowering pool water below skimmer for solid covered pools or 18” below deck level for mesh covered pools, Draining all pool equipment of water, Blowing out and plugging all underground plumbing lines, Removing grab rails and ladders, Adding antifreeze to lines and skimmers, Adding Winter Algaecide, Stain & Scale Inhibitor, and Chlorine shock to water, Testing and Balancing water chemistry (ALL CHEMICALS EXTRA)


Includes BASIC Closing plus installation of Mesh Winter Cover (Solid covers with waterbags – Add $20)


Includes BASIC Opening; Cover Removal; and ½ hour of vacuuming with our external pump (additional ½ hours at $60 per half hour)


Protect your pool over the Winter with our Full Winter Service, which includes four (4) service visits monthly over the Winter to make sure the cover is properly attached, chemistry is properly balanced, pool equipment is undisturbed, and the water level remains below the tile line. A Winter Chemical Booster of Algaecide and Chlorine is also added at the final visit to help minimize algae growth in the early-Spring.

*The pricing given is based on pools up to 35,000 gallons and does not include chemical costs, which are a variable based on the size of pool, number of skimmers, and water condition at the time of Closing.


"The pool looks brand new......it is 27 years old. They also put a dolphin and beach balls on the bottom (made out of tiles) to show where the pool depth changes. I use this company now to maintain the pool and keep it in good shape. They are very good at keeping problems from happening."

"Pooltek exceeded my expectations. We opted for a somewhat minimal service, but my pool was left sparkling and ready for winter. Even in October, they were booked out a bit (good sign), but we had them come as soon as possible.

They showed up and got right to work cleaning out the mess of old leaves we weren't able to get ourselves. The techs were professional and friendly and offered some advice on my options.

Their prices are very reasonable! Highly recommended!"


This summer [we] decided to put the maintenance of our pool in the hands of the pros, and we signed on for your weekly Tek service. It was a great decision! The tech team has helped us overcome an unusual set of water chemical challenges, and they have completely succeeded. After the team’s hard work, the pool water is now crystal clear and completely inviting.

We also asked your team to update our aging sand filter, and we have been thoroughly impressed – with their work and their cheerful competence.

I had quite a few pool companies come out for quotes and nobody was near as responsive (if at all) or their quotes were just outrageous. We definitely feel we made the right choice going with Pooltek…great customer service!
