What a Pool Service Does Each Visit
A standard weekly pool service visit includes skimming, brushing walls and steps, vacuuming as needed, emptying skimmer and pump baskets, full water testing (chlorine, pH, alkalinity, stabilizer), chemical dosing, and an equipment check of pump, filter pressure, and visible leaks. Usually extra: filter deep-cleaning, salt cell cleaning, repairs, and stain or algae treatments. Verify the work with your own test kit monthly and watch for rushed 10-minute visits.
The full visit checklist, the common extras, and how to verify the work.
The standard visit checklist
A proper weekly visit follows a sequence. First, a visual check: water level, clarity, equipment running normally, no visible leaks. Then skimming the surface and emptying skimmer and pump baskets. Then brushing the walls, steps, and waterline tile, which prevents algae from gaining a foothold on surfaces. Then vacuuming, full or spot depending on debris. Then water testing: free chlorine, pH, total alkalinity, and cyanuric acid at minimum, calcium hardness monthly. Then chemical dosing to correct the readings. Finally, an equipment check: filter pressure against its clean baseline, pump sounds, heater status, and timer settings.
That is 30 to 45 minutes for a straightforward pool. Ten-minute visits are the industry's open secret on overbooked routes, and they skip exactly the steps that prevent problems: brushing and full testing. If your tech is in and out in 10 minutes every week, you are paying for skimming and hoping.
What is usually extra
Filter deep-cleaning, quarterly or as pressure dictates, is often a separate charge of $75 to $150. Salt cell inspection and acid cleaning is extra. Algae treatment beyond routine shocking is extra. Stain removal, phosphate treatment, and any repair, pump seals, cleaner parts, light bulbs, are billed separately with your approval. None of this is unreasonable; it is unreasonable only when it surprises you. Ask for the extras list before signing, not after the first invoice.
Chemicals: included or billed
Companies split three ways: chemicals included in the monthly rate, chemicals billed as used, or a hybrid with basics included and specialty chemicals extra. Included-chemical plans align incentives: the company wants efficient dosing. Billed-as-used plans can incentivize overdosing, though reputable companies do not. In 2026's elevated chemical market, the difference between the models can be $30 to $80 per month. Get the policy in writing and compare all-in monthly cost, not the visit fee.
How to audit your service
Buy a $15 test kit and check chlorine and pH yourself once a month, ideally the day after a visit. Log the readings. If your numbers consistently disagree with the tech's, or if algae appears between visits, the service is failing. Walk the equipment pad monthly: listen for new pump noises, check for drips, note the filter pressure. Photograph anything odd and email it; the paper trail matters if equipment fails.
Seasonal audits matter more. After storms, check that the tech actually came; after vacations, verify chemistry before swimming. The best customers are informed ones: a tech who knows you test does better work, and a company that knows you log visits staffs your route properly.
When to change companies
Change when visits are consistently rushed, when chemistry is chronically off despite your log showing it, when extras appear without prior approval, or when communication fails (no response to the green-pool text within a day). Get the new company's extras list and chemical policy before canceling the old one, and overlap a week if you can: the new tech's first visit doubles as an independent assessment of what the old company left behind.
When you interview replacements, ask three questions that reveal quality. How long is a typical visit on your route, and how many stops does the tech make per day? What exactly is included versus extra, in writing? And what happens when my pool turns green, who responds and how fast? Companies with reasonable route sizes, clear extras lists, and a real emergency protocol are worth 20% more than the cheapest quote. The cheapest route in town is cheap because the tech has 40 stops a day, and your pool gets 10 minutes.
