The 2025-2026 Winter Pool Maintenance Checklist Every McKinney Homeowner Needs

If you’ve lived in McKinney, Frisco, Prosper, Allen, Plano, or Celina for more than one winter, you already know the deal. One week you’re in shorts pressure-washing the patio, the next week the kids are off school for an “ice day” and your pool equipment looks like it got hit by a frozen hammer.

We’ve been keeping pools perfect in Collin County since May 2018, and every spring we see the same two groups of homeowners:

Group A: The ones who followed a simple winter routine (or had us do it). Their pool opens in March for a normal price and they’re swimming by spring break.

Group B: The ones who closed the gate in October and didn’t look back. They’re the ones dropping $3,000–$10,000 in April on new pumps, filters, heaters, cracked plumbing, and full algae clean-outs because everything froze, flooded, or turned into a swamp.

The difference is literally five minutes a week and one or two weekends all winter. That’s it.

Below is the exact winter maintenance checklist our techs live by. Print it, screenshot it, stick it on the fridge — whatever works. Do these things and you’ll be Group A.

Part 1: A Quick 5-Minute Walk-Around Every Week

  1. Water level check – Even under a solid safety cover, small leaks and evaporation happen. If the water drops below the skimmer by more than 3–4 inches, something’s leaking.
  2. Cover inspection – Look for standing water, heavy leaf piles, torn mesh, or broken straps. Pump water off within 24 hours (a cheap cover pump pays for itself the first big rain).
  3. Equipment pad glance – Any puddles under the pump or filter? Ice forming on pipes? Weird smells? These are early warnings.
  4. If your pool is still open and running (heated pools or spas): Check filter pressure. 8–10 psi higher than clean = backwash or clean the cartridge.
  5. Animal damage patrol – Raccoons and squirrels love ripping mesh covers this time of year. A small hole in November becomes a giant leaf catcher by February.

Do these five things every week and you’ll catch 95% of problems before they become four-figure repairs.

Part 2: Monthly Maintenance (30–60 Minutes)

  • Full water test – Yes, even in winter. Bring a sample to us or use good test strips. pH climbs when water sits cold, and high pH means scale on your heater and salt cell. Low alkalinity + cold water = metal stains.
  • Brush exposed areas – Top two steps, benches, and any visible walls. Algae grows slower in cold water, but it still grows.
  • Net or vacuum large debris off the cover – Wet leaves turn into acidic soup that eats threads and stains the cover.
  • Run the system for 30–60 minutes (if you keep it open). Keeps seals lubricated and bearings happy.
  • Check your automation app or time clock – Make sure freeze protection is still ON and the sensor hasn’t been bumped.

Part 3: The 24–48 Hour Hard-Freeze Game Plan

Every time the forecast shows lows below 28° overnight, do this immediately:

  • Turn the pump on and leave it running 24/7 until nighttime lows stay above 35°
  • Open every valve: waterfalls, fountains, sheer descents, spa spillways (yes, even if it looks silly)
  • Clean skimmer and pump baskets — packed wet leaves block flow faster than anything
  • Test the freeze guard sensor with the ice-water cup trick (30 seconds)
  • Have towels ready for thaw leaks
  • If the power grid looks shaky, know exactly where your drain plugs are

Part 4: Red-Flag Emergencies — Contact Us Immediately (469-352-9191)

  • Water level dropping more than an inch a week
  • Green/black water visible under a mesh cover
  • Pump making grinding, screaming, or no noise at all
  • Heater throwing error codes
  • Safety cover sagging or straps popping
  • Ice forming on equipment pipes while the pump is running
  • Any chemical or burning smell from the pad

Don’t Worry, Pool Scouts Has You Covered!

If you read that checklist and immediately thought “Hard pass,” you’re not alone. Most of our customers feel the same way once the holidays hit.

That’s why we offer two dead-simple ways to hand the keys to the pros:

  1. Full Professional Winterization (Pool Closing)
    We come out once (ideally November or early December), do everything the right way, and your pool sleeps safely until spring. Includes:

    • Lowering water level below returns and skimmers
    • Blowing out every line with a commercial compressor (pool, spa, waterfalls, cleaner line — nothing left to freeze)
    • Adding non-toxic antifreeze where needed
    • Draining and plugging pump, filter, heater, chlorinator — everything
    • Winter chemical treatment
    • Installing or properly securing your safety cover (no sagging, no gaps)
    • Takes us about an hour, costs most homes $249–$399 depending on features, and saves thousands in potential repairs.
  1. DIY Assist Membership

Perfect for hands-on owners who want pro backup all year. You get:

    • Two annual equipment check-ups (one is your full winter-ready inspection)
    • Comprehensive diagnostic report
    • 10-point water test
    • 19% off repairs and chemicals
    • Free delivery on chemical orders over $150
    • Dedicated pro hotline
      All for $199.99 prepaid or $19/month.
    • Basically, we sticker everything, teach you exactly what to do (or do it for you), and you have us on speed dial all winter.

Your Printable 2025-2026 Winter Pool Checklist

Copy this into your phone or print it:

  • Nov 15–30: Full water test & balance, clean baskets, test freeze guard, schedule winterization if wanted
  • Every Friday: 5-minute walk-around + pump water off cover
  • December, January, February: Monthly brush/test/large-debris removal
  • Before every hard freeze: 24/7 pump, open all features, clean baskets
  • February 1–15: Book your 2026 pool opening (slots fill crazy-fast)
  • March 1: Smile because your pool isn’t a disaster

Follow that checklist and your biggest problem next spring will be deciding which pool float to buy first.

Don’t want to follow the checklist? Totally fair. Text or call us right now at 469-352-9191 and say “Winterize me before the next freeze.”

We still have openings, but once that first big cold front shows up on the forecast, the schedule fills faster than H-E-B before an ice storm.

Stay warm, stay dry, and keep that pool happy all winter.
