When deciding how often to service a swimming pool, swimming pool owners typically choose between weekly, fortnightly (every two weeks) and monthly schedules. Each option has pros and cons depending on factors including pool usage, temperature and budget. Here’s a breakdown of the advantages and disadvantages of each:
Weekly Pool Servicing
Pros:
- Optimal Pool Maintenance: A weekly service ensures your pool remains clean and well-maintained, preventing issues like algae growth, debris buildup or water imbalances.
- Consistent Water Quality: Pool chemicals like chlorine, pH balance and alkalinity are checked frequently, ensuring your water stays healthy and safe for swimmers.
- Prevents Major Issues: Regular servicing catches minor problems like pump issues, leaks or dirty filters early, potentially saving you from expensive repairs.
- Ideal for Frequent Pool Use: If your pool is used regularly, weekly servicing will help maintain its cleanliness and efficiency, saving you time, money and stress!
Cons:
- Higher Costs: Weekly servicing can be more expensive as it involves more labour and supplies.
- Potential Over-service: If your pool is rarely used, weekly servicing might be too much and lead to unnecessary chemical treatments or cleaning.
Fortnightly (Every Two Weeks) Pool Servicing
Pros:
- Balanced Frequency: Fortnightly servicing strikes a good balance for pools that aren’t used daily. It’s sufficient to maintain cleanliness and chemical balance without over-servicing.
- Cost-Effective: Fortnightly servicing is less expensive than weekly visits, making it more manageable for those on a budget.
- Efficient for Moderate Pool Use: Fortnightly visits are adequate if your pool is used only occasionally or during specific seasons.
Cons:
- Less Frequent Monitoring: With two-week intervals, there’s a greater risk of neglecting issues like algae growth or debris accumulation, especially if there’s a heavy storm or unexpected pool use.
- Potential Water Imbalance: Water chemistry might not be checked as frequently, increasing the risk of pH imbalance, cloudy water or skin irritation for swimmers.
- Possible Maintenance Delays: Mechanical issues might not get detected until the next visit, making them worse when the technician visits.

Monthly Pool Servicing
Pros:
- Lowest Cost: Monthly servicing is the most budget-friendly option as it involves fewer visits and less frequent maintenance.
- Sufficient for Low-Use Pools: Monthly visits might be enough to keep the pool in decent condition for pools used infrequently (e.g. vacation home).
- Convenience for Infrequent Use: Monthly visits are convenient and affordable if the pool isn't your main focus and you don’t mind occasional water quality issues.
Cons:
- Higher Risk of Problems: With only monthly maintenance, issues like algae growth, clogged filters or equipment malfunction may go unnoticed, leading to potentially larger problems down the road.
- Water Quality Risks: Chemical imbalances may develop, affecting water clarity, swimmer health or damaging pool equipment if not caught quickly.
- Labour-Intensive for the Homeowner: Between monthly services, you may need to perform more maintenance, which could be time-consuming and burdensome.
The Resolve
Choosing the right pool service frequency depends on pool usage, climate and budget. Weekly services are ideal for heavily used pools or ensuring the highest level of maintenance. Fortnightly services balance cost and maintenance, while monthly services are best for pools with infrequent use.
