Whether you need routine pool maintenance, expert repairs, or seasonal pool openings and closings, we’re here to help.

What Are Residential Pool Services?

Residential pool services cover everything required to keep your backyard pool running smoothly year-round. Our services in Northern Virginia include:

Do I Still Need an Automatic Pool Cleaner?

Yes, and here’s why: An automatic pool vacuum handles basic surface cleaning and debris removal, but it doesn’t monitor water chemistry or service your equipment. Professional pool service ensures every part of your system is working properly and safely. Think of it as the difference between sweeping the floor and having a deep-clean.

How Often Should I Test My Pool Water?

We recommend testing your pool water at least twice a week, especially during the summer or high-swim-load weekends. Testing more often helps catch problems early and avoid major chemical imbalances.

My Pool Looks Clean—Do I Still Need Weekly Pool Service?

Yes. Clear water can still hide unbalanced pH, bacteria, or unsafe chlorine levels. Weekly pool service ensures your water is truly safe, your equipment is working correctly, and minor issues don’t turn into costly repairs. Especially in areas like Burke or Oakton, where tree debris and temperature swings can affect your pool, regular service makes a big difference.

Is There a Standard Chemical Formula for Pools?

Nope. Every pool is unique. Your chemical needs depend on size, surface material, location, sunlight, and usage. We personalize your treatment based on real-time water test results, not guesswork.

What’s the Difference Between Shocking and Breakpoint Chlorination?

Pool shocking increases chlorine to kill bacteria, while breakpoint chlorination removes combined chlorine (which causes odor and irritation). If your water smells like chlorine, it probably needs a breakpoint treatment—not more chlorine.

How Long After Chemical Treatment Can I Swim?

Usually 8 to 12 hours. We’ll let you know each time we add chemicals when it’s safe to re-enter the pool. Safety always comes first.

What’s Included in a Pool Opening Service?

Our pool opening services in Northern Virginia include:

  • Cover removal and storage
  • Reinstalling plugs and fittings
  • Equipment setup and testing
  • Water testing and chemical balancing
  • Skimming, vacuuming, and system priming
  • Leak inspection and circulation check

We’ll make sure your pool is clean, balanced, and ready for fun.

What About Pool Closings?

Pool closing is just as important. Our service includes:

  • Water level adjustment
  • Line winterization
  • Removing ladders, handrails, and equipment
  • Chemical treatment for winter
  • Cover installation
  • System drainage and equipment protection

This helps prevent freeze damage and makes next season’s opening much easier.

Should I Drain My Pool Over Winter?

No. Draining your pool for winter can damage the plaster and compromise structural integrity. We use professional winterization methods that keep your pool full, protected, and chemically balanced until spring.

Do You Offer Weekly Pool Service in My Area?

Yes! We offer residential pool services throughout Fairfax County, Arlington, Loudoun County, Falls Church, Vienna, Great Falls, McLean, Reston, and nearby cities. Weekly and biweekly plans are available depending on your needs and budget.

I Have a Saltwater Pool—Does It Still Need Maintenance?

Absolutely. Saltwater systems still generate chlorine and require regular maintenance. You’ll still need to brush, vacuum, check the salt cell, and monitor the system’s controller. We can take care of all of this for you.

Can I Save Money by Doing It Myself?

In the short term, it might seem cheaper to DIY. But one bad chemical mix or a missed issue can cause damage that costs hundreds—or even thousands—to fix. Professional pool service saves you time, stress, and long-term expense.

What Pool Equipment Do You Repair?

Our pool equipment repair services include:

  • Pumps and motors
  • Filters (sand, DE, and cartridge)
  • Heaters and timers
  • Salt system controllers
  • Pool automation systems
  • Cleaners and skimmers

If your water is cloudy, your system is loud, or your pressure is off, call us.

What Pool Equipment May Need Replacing?

Over time, equipment wears out. The most common pool upgrades we install include:

  • Energy-efficient variable speed pumps
  • Smart automation systems
  • High-performance filtration systems
  • Salt system replacements
  • LED lighting systems

We’ll evaluate your system and recommend repairs or replacements that make sense for your pool and budget.
