Weekly Pool Service in Hercules, CA

G-Whizz Pool Cleaning delivers consistent, thorough weekly pool service to homeowners in Hercules, Pinole, Concord, Lafayette, Walnut Creek, Pleasant Hill, and Martinez. Every visit comes with a photo and a written report, guaranteed.

Surface Skimming

We remove all floating debris including leaves, insects, and pollen from the water surface before they sink and begin to decompose. Skimming every visit keeps your filter from working overtime.

Wall and Step Brushing

Brushing the pool walls, steps, and benches on every visit prevents algae from establishing a foothold on the surface. This step is easy to skip but critical for preventing a green pool situation.

Water Chemistry Testing and Balancing

We test pH, chlorine or salt output, alkalinity, calcium hardness, and stabilizer levels on every visit. Balanced water protects your pool surface, equipment, and the health of your swimmers.

Basket Emptying

Skimmer and pump baskets are emptied at every visit. A clogged basket reduces flow to your pump, increases energy consumption, and can cause the pump to run dry. This is one of the simplest and most impactful maintenance steps.

Equipment Inspection

Our technicians check your pump, filter, heater, and salt system during every service call. Early detection of unusual pressure, noises, or leaks prevents small issues from becoming expensive failures.

Photo Report After Every Clean

After every visit, we send you a photo of your completed pool along with a written report on water chemistry readings and equipment observations. You always have a record of every service we performed.

Professional-Grade Sanitizers

We use professional-grade chlorine products from established pool supply lines, including trichlor tablets, dichlor shock, and liquid chlorine depending on your pool's needs and your current system type. For salt pools, we monitor cell output and salt concentration rather than adding sanitizers directly, ensuring the salt chlorinator is working as intended. We adjust our chemical approach based on your specific pool chemistry readings, not a one-size-fits-all formula.

Balancing Agents and Algaecides

For pH and alkalinity adjustment, we work with products from the BioGuard and HTH professional lines, along with cyanuric acid stabilizers to protect chlorine from UV breakdown. When we encounter early signs of algae growth during a visit, we apply preventive algaecide immediately rather than waiting for a full outbreak. Catching algae early is far less disruptive and far less costly than a full green pool treatment. If your pool has gotten to that point already, our green pool recovery service is the right starting point.

Chemical testing performed during every weekly visit

Our technician walks the pool perimeter before touching the water. We check water color and clarity, look for any visible equipment issues, and assess how much debris has accumulated since the last visit.

This quick scan helps us decide whether vacuuming is needed and whether any additional treatment is warranted before we begin.

We test the water using a professional-grade test kit that reads pH, free chlorine, total alkalinity, cyanuric acid, and calcium hardness. For salt pools, we also test the salt concentration and cell output reading.

Knowing the chemistry before we clean tells us which adjustments to make and in what order, so chemicals are effective rather than just added.

We skim the surface, brush the walls and steps, empty all baskets, and vacuum the floor where needed. The order matters: we move debris toward the main drain before vacuuming so the filter captures it efficiently.

Chemical adjustments are made after cleaning is complete so readings are accurate and treatment is consistent.

After we finish, we photograph the completed pool and compile a written report with your chemical readings, basket and equipment status, and any observations from the visit.

You receive this every single week so you always know we were there, and you always know the state of your pool.

Signs Your Pool Needs Weekly Service Now

Pools that go without regular care deteriorate faster than most homeowners expect. These are the signs that tell us a pool has been without consistent weekly service.

• Water has taken on a cloudy, dull, or greenish tint that clears slowly or not at all
• Algae is visible on the walls or steps, especially in shaded areas of the pool
• Your pool smells heavily of chlorine even though you keep adding it
• You notice debris accumulating on the bottom between cleanings faster than before

What consistent weekly service prevents:

• Green pool outbreaks that require intensive chemical treatment
• Calcium scaling on pool surfaces and equipment
• Premature wear on pumps and filters from dirty water
• Costly equipment repairs caused by undetected leaks or pressure issues
• Unhealthy water chemistry that affects swimmers

Everything in One Visit

Our weekly pool service is designed so that you never have to schedule separate visits for cleaning versus chemistry versus equipment checks. We handle all three in a single weekly call. The cost of chemicals used during the visit is included in your service agreement, and we document every adjustment so you have a running history of your pool's health.

If we catch an equipment issue that requires a repair, we give you a free written quote after seeing the problem. We never do repair work without your approval, and because our team handles pool equipment repair in-house, there is no gap between detection and resolution.

The Clean Pool Guarantee

We stand behind our work. If you are not satisfied with a weekly cleaning, contact us and we will return to address it. As a locally owned company serving the Contra Costa County area, our reputation depends on the results we deliver, not just the visits we make.

This guarantee is not a marketing phrase. It is how we have operated since we opened 6 years ago, and it is why our customers in Hercules and across the region stay with us. We give a free written quote after seeing your situation, no pressure.
