Pool care, considered
and properly delivered.
Practice-led by John Brennan with over 25 years of pool industry experience — trained across QLD, NT and NSW. John sets and oversees the standard, and his trained team delivers Master-Level Care on every engagement. Honest advice, no upselling, no shortcuts.
A clean pool is more than a surface look.
Most pool problems begin quietly — a small chemistry imbalance, a tired filter, a build-up at the waterline. Caught early, they're a five-minute adjustment. Left alone, they become a weekend. Considered cleaning is the difference.
Water chemistry, properly held
pH, chlorine, alkalinity and calcium all sit in narrow ranges. We test with calibrated equipment and adjust precisely — not by eye, not by guess.
Surfaces, kept honest
Walls, floor and waterline are brushed and vacuumed every visit. Algae and stains never get the chance to settle in — and your interior keeps its finish for longer.
Equipment, watched closely
Pumps, filters, chlorinators and seals are inspected each visit. Worn parts get flagged early — before they fail mid-summer and cost ten times more to fix.
"A pool well looked after is a pool you stop thinking about. That's the goal — quiet, dependable, ready when you are." — John Brennan
The work you can't see is the work that matters.
Skimming leaves and topping up chlorine is the easy bit. The harder work — proper chemistry balance, equipment diagnostics, spotting wear before it fails — takes training and the right instruments. That's what twenty-five years on the tools teaches you to do quickly.
DIY routines tend to miss the early signs. A pool that "looks fine" can already be drifting toward an algae bloom or scaling on the heater. Regular professional service catches it at the chemistry stage, not the chaos stage.
Take Action Today
- Book a one-off assessment if you've never had a pro look
- Get on a regular schedule before peak season demand hits
- Ask for an honest equipment health report — no upsell
If you're seeing any of these, it's time.
Cloudy or hazy water
Even after running the pump — usually a chemistry or filtration issue.
Green tinge or visible algae
On walls, in corners, around lights or steps. Catch it early; it doubles overnight.
Skin or eye irritation after swimming
A reliable sign that pH or sanitiser levels have drifted out of range.
Stains on walls or floor
Iron, organic, or calcium stains all need different treatments — not just a brush.
Pump or filter running noisier than usual
Whining, rattling, or pressure climbing — flag it before it becomes a replacement.
You haven't tested water in a fortnight
Then chemistry has likely drifted, even if the pool still looks clear.
"If something feels off, it usually is. Better to call early than scramble in the heat." — John Brennan Pools
Six steps. Every visit. No shortcuts.
Twenty-five years has taught us a rhythm. Here's exactly what happens when the John Brennan Pools team pulls into your driveway.
Visual inspection
Walk the perimeter. Check water clarity, level, deck condition, equipment housing — note anything new before we touch a thing.
Skim and clear
Surface debris off, baskets emptied — skimmer, pump, robot if present. Clean intake means accurate chemistry tests.
Brush and vacuum
Walls, floor, waterline, steps — brushed, then vacuumed. Algae spores live in the spots a robot misses.
Test and balance
Calibrated test of pH, chlorine, alkalinity, calcium and stabiliser. Adjustments made and noted on your service log.
Equipment check
Pump pressure, filter cleanliness, chlorinator output, seals, valves. Anything wearing gets flagged before it fails.
Honest report
What was done, what was added, what to watch. No mystery charges, no surprise upgrades. Just the work — properly explained.
"Same six steps every visit. That's how problems stay small — because nothing slips past." — John Brennan Pools

From struggling to sorted.
Two recent jobs across the Central Coast — owners who'd been managing on their own, then handed it over.
Recurring algae blooms — finally gone.
The owner had been chasing the same problem every spring. We rebuilt the chemistry baseline, adjusted run-times, and moved them to a fortnightly schedule. The pool has stayed clear ever since.
A worn seal caught before it failed.
Circulation had been quietly dropping for weeks. A routine equipment check during a cleaning visit found a tired pump seal — replaced on the spot, full circulation restored, breakdown averted.
Six small habits that protect your pool between services.
Run the pump long enough
In summer, eight hours minimum. Off-peak overnight is fine, but the water needs to turn over each day to stay clear.
Empty skimmer baskets weekly
Full baskets choke flow and force the pump to work harder. Thirty seconds, every weekend. That's the whole job.
Watch the water level
Mid-skimmer is the sweet spot. Too low starves the pump; too high and the skimmer can't do its job.
Rinse swimmers off first
Sunscreen, deodorant and hair products all add demand on chlorine. A quick rinse before swimming saves chemistry later.
Cover when not in use
A cover slashes evaporation, keeps debris out, and holds heat overnight. Pays for itself within a season or two.
Call early, not late
If something looks off, ring. A two-minute phone call now avoids a Saturday morning emergency next week.
Pool cleaning, answered plainly.
How often should a swimming pool be professionally cleaned on the NSW Central Coast?
Most residential pools on the NSW Central Coast need professional cleaning every two to four weeks during peak swimming season (roughly October to March) and every four to six weeks through the cooler months. Pools with heavy use, overhanging trees, or a history of algae need the two-week interval. John Brennan Pools sets each cleaning schedule around the specific pool rather than applying a fixed cycle.
What is included in a professional pool cleaning service from John Brennan Pools?
A John Brennan Pools cleaning visit includes eight steps: a calibrated water test of pH, chlorine, alkalinity, calcium and stabiliser; surface skimming; brushing and vacuuming of the walls, floor and waterline; emptying the skimmer and pump baskets; an equipment inspection; a filter clean or backwash as required; and a written service log. Every item is completed on every visit by John Brennan Pools' trained team to the Master-Level Care standard John Brennan sets and oversees, with no upselling.
How much does professional pool cleaning cost on the Central Coast?
Professional pool cleaning is priced on three factors: pool size, current water and surface condition, and service frequency — a regular fortnightly clean costs less per visit than a one-off recovery of a neglected pool. John Brennan Pools provides a clear, fixed quote up front with no hidden charges or surprise upgrades. Call John Brennan Pools on 0491 180 575 for a price tailored to your pool.
Can I clean my own pool myself instead of hiring a professional pool service?
Yes, you can handle the basics yourself — skimming debris, emptying baskets and topping up chlorine — but professional cleaning covers the work that is easy to miss: precise chemistry balancing with calibrated equipment, equipment diagnostics, and spotting wear before it fails. DIY routines tend to catch problems at the chaos stage rather than the chemistry stage, which costs far more to fix. A regular professional service from John Brennan Pools keeps small issues small.
What are the signs that a pool needs cleaning or that the water is unbalanced?
The five clearest signs a pool needs cleaning are cloudy or hazy water, a green tinge or visible algae, skin or eye irritation after swimming, a strong chlorine smell, and stains on the walls or floor. Any one of these means the water chemistry has drifted out of its correct range. A calibrated water test from John Brennan Pools confirms exactly where pH, sanitiser, alkalinity and calcium sit so the right correction can be made.
Who actually does the work when you book a clean with John Brennan Pools?
Every John Brennan Pools clean is carried out by a trained service team working to standards that owner and Practice Lead John Brennan sets and personally oversees. John Brennan Pools is a practice-led business, so each pool receives the same Master-Level Care on every engagement rather than a roster of strangers cycling through your gate. The principle behind it is simple: uncompromising standards, because your pool is an investment, not just a backyard feature.
