Annual Pool Openings & Closings

Professional seasonal pool service to get you swimming in spring and protected for winter.

Seasonal Pool Service for Colorado

Colorado's distinct seasons mean your pool needs proper care when opening for summer and closing for winter. DND Spas provides complete seasonal pool service for both above ground and in-ground pools, ensuring your pool is ready when you want to swim and properly protected when the cold arrives.

Above Ground Pool Opening

When spring arrives and it is time to swim again, our team handles every step of your above ground pool opening:

1

Cover Removal

Carefully remove and fold the winter cover for storage.

2

Pump & Filter Assembly

Reassemble and connect the pump and filtration system.

3

Equipment Inspection

Inspect all equipment for damage from winter storage or wear.

4

Cleaning

Clean the pool interior, remove debris, and prepare for water treatment.

Above Ground Pool Closing

Proper winterization protects your pool from Colorado's freeze-thaw cycles and extends the life of your equipment:

1

Thorough Cleaning

Clean walls, floor, and waterline before winterizing.

2

Drain & Disconnect

Drain water to proper level and disconnect all plumbing lines.

3

Disassemble Equipment

Disassemble pump, filter, and other equipment for safe winter storage.

4

Cover Installation

Securely install the winter cover to protect from debris and weather.

Note About Ladders & Steps

Removal and reinstallation of ladders and steps is the client's responsibility. If you need assistance with these items, please let us know when scheduling and we can discuss options.


In-Ground Pool Opening

In-ground pool openings involve more steps due to the additional equipment and plumbing. Our team handles everything:

Cover Removal

Carefully remove the winter cover, clean it, and fold for storage.

Ladder & Diving Board Installation

Reinstall ladders, diving boards, and any other removed accessories.

Pump Station Assembly

Reassemble the pump station, reconnect plumbing, and prime the system.

Heater Inspection & Startup

Inspect the heater for any off-season issues and start it up for the season.

What to Expect After Opening

After your pool is opened, there are some routine tasks to keep things running smoothly during the first few days:

  • Backwash the sand filter daily for the first several days until the water clears.
  • Clean skimmer and pump baskets regularly to maintain proper water flow.
  • Vacuum and skim daily until the pool is clear of debris and sediment.
  • Test the water and adjust chemistry as needed to reach safe, balanced levels.

In-Ground Pool Closing

Winterizing an in-ground pool properly is essential to prevent freeze damage to pipes, equipment, and the pool shell itself. Our closing service includes:

Thorough Cleaning

Clean the entire pool including walls, floor, and waterline before winterizing.

Remove Fittings & Ladders

Remove all return fittings, ladders, diving boards, and other removable accessories.

Blow Out Lines

Use compressed air to blow all water out of plumbing lines to prevent freeze damage.

Disconnect Plumbing

Disconnect all plumbing connections to prevent ice expansion damage.

Disassemble Pump Station

Disassemble and store the pump, filter, and related equipment safely indoors.

Cover Installation

Securely install the winter cover with anchors or water bags for a tight seal.

Additional Appendage Fees

Pools with non-standard equipment, extra return lines, specialty heaters, or other additional appendages may incur additional fees. We will provide a clear quote before starting any work so there are no surprises.
