Service quality is what keeps customers from shopping your price. Most quality issues are small, consistent, and noticed within 30 seconds of the customer walking out to the pool.
The 5-point post-service walkthrough (60 seconds).
1. Water clear? (basic but checked first by customers)
2. Coping and tile area free of debris?
3. Skimmer and pump baskets emptied?
4. Pool gate latched, equipment area tidy?
5. Service report visible (door hanger, app notification, or text)?
Test before, dose, retest after. Document chlorine and pH at start. Document at end. Customers (and disputes) are won and lost on the test log. Every modern routing app supports this.
Photo on every visit. Most apps support attaching photos to service reports. A weekly clean-pool photo is the single most powerful retention tool, customers rarely look at the pool the moment you leave, but they always look at the photo on their phone.
Communication on issues. Found something off (low water, faulty heater, cracked tile)? Photo + 1-line text *before* you leave the property. Bills get disputed when customers feel blindsided; never when they were warned.
Service consistency review. Once a quarter, ride your own routes (or have your lead tech ride yours) with a fresh eye. Things slip. Quality drift is invisible until you measure it.
