Pool Opening & Closing Services

Seasonal Pool Care in San Mateo

While San Mateo's mild climate means you can technically swim year-round, most pool owners use their pools primarily from late spring through early fall. Our pool opening and closing services in San Mateo help you prepare your pool for swim season and protect it during the cooler months when you're not swimming. Proper seasonal maintenance prevents problems and saves you money on chemicals and energy.

Opening and closing a pool properly takes time and expertise. You need to balance chemistry carefully, check all equipment, and perform specific procedures in the right order. Skip steps or do them wrong, and you can end up with algae blooms, equipment damage, or expensive repairs. We handle everything correctly so your pool is ready when you want it and protected when you don't.

Spring Pool Opening Service

When warm weather arrives and you're ready to swim again, we get your pool in perfect condition. Here's everything included in our spring opening service:

• •Remove Winter Cover: We carefully remove, clean, and store your pool cover if you use one, checking for any damage that needs repair before next winter.
• •Clean and Inspect: We remove any debris, leaves, and algae that accumulated over winter. We inspect all pool surfaces for cracks, stains, or damage.
• •Reinstall Equipment: We reconnect and reinstall any equipment that was removed for winter, including ladders, diving boards, and accessories.
• •Start Up Systems: We start your pump, filter, and heater, checking for leaks or problems. We prime pumps, set timers, and verify everything runs correctly.
• •Balance Water Chemistry: We test and balance all chemical levels, shock the pool if needed, and add algaecide to prevent early-season algae growth.
• •Vacuum and Brush: We thoroughly vacuum the pool floor and brush all surfaces to remove winter buildup and prepare for swimming.

After opening, your pool might need a few days of circulation and filtration before it's perfectly clear and swim-ready. We'll let you know exactly when you can jump in. If your pool is particularly dirty after winter, we can combine opening with our deep cleaning service for the best results.

Fall Pool Closing Service

When swim season ends, proper closing protects your pool and equipment through winter. Here's what we do:

We thoroughly clean the pool first so no algae or debris sits in the water all winter. We balance the water chemistry to prevent corrosion and staining, adding winterizing chemicals that keep water stable for months. We lower the water level to the proper height (usually just below the skimmer) to prevent freeze-related damage if temperatures drop unexpectedly.

Equipment preparation is critical. We blow out all plumbing lines to remove water that could freeze and crack pipes. We drain pumps, filters, and heaters, removing drain plugs to prevent water accumulation. We disconnect and store sensitive equipment if needed. We add antifreeze to lines that can't be completely drained.

Finally, we install your pool cover properly, ensuring it's secure and will keep out debris and sunlight. A good cover makes spring opening much easier because your water stays cleaner over winter. Even in San Mateo's mild climate, proper closing prevents problems and makes your pool easier to maintain during the off-season.

Year-Round Maintenance Alternative

Many San Mateo pool owners choose to keep their pools operational year-round with reduced maintenance rather than fully closing. This makes sense in our climate where you might want a warm-day swim even in January or February. With year-round service, we come less frequently during winter (maybe twice a month instead of weekly) and run equipment on reduced schedules to save energy.

Year-round maintenance costs more than closing your pool completely, but it means your pool is always ready if you want to swim. It also prevents stagnation problems that can happen when pools sit unused for months. Many customers prefer this option because it's easier on equipment (regular operation is better than shutting down and restarting) and there's no big opening/closing expense each year. Our weekly service can be adjusted seasonally to provide the right level of care year-round.
