Miguel R.Cascais
Impeccable service. Since they started looking after the pool we have practically stopped thinking about it. When we arrive at the weekend it is always clean and ready. They are punctual and, when there is a problem, they let us know straight away.
★★★★★
Ana M.Estoril
They have been working with us for a few months and we are very happy. They do the maintenance even when we are not home and then send photos and the water readings on WhatsApp. It gives a lot of confidence.
★★★★★
Ricardo S.Sintra
Our pool was green and we had already tried to fix it without success. They came over, explained the problem and the next day the difference was huge. They also warned us about a filter problem that was making things worse.
★★★★★
Pedro C.Oeiras
We needed the whole plant room renewed and they did a very careful job. They replaced the pump, filter and panel, left everything tidy and explained how it works. Since then, maintenance has been much simpler.

Talk to usTips
What is worth knowing about your pool.
Four things we explain to every client on the first visit.
24 his how long to see if it recovers on its own
The water turned green. What to do in the first hours?
Keep filtering: run the pump continuously and backwash the filter. Test the pH and bring it to 7.2 to 7.6 before adding chlorine, otherwise the chlorine will not work. Shock the pool at the end of the day and leave the filtration running all night. If it is still green after 24 hours, something else is going on: a saturated filter, a weak pump or high cyanuric acid. At that point, send us a photo.
7.2 to 7.6is the pH where everything works
What readings should pool water have?
pH between 7.2 and 7.6. Free chlorine between 1 and 3 ppm (0.5 to 2 in public-use pools). Alkalinity between 80 and 120 ppm, which is what keeps the pH stable. Cyanuric acid between 30 and 50 ppm: above 75, chlorine stops disinfecting properly and the fix is to replace part of the water. In salt pools, 2,500 to 3,500 ppm of salt.
8 hof filtering a day, in summer
How long should the pool filter each day?
The whole volume of the pool should pass through the filter at least one and a half times a day. For a 50 m³ pool with a 10 m³ per hour pump, that is 8 hours, preferably in daytime, when the sun burns off chlorine. In summer with heavy use, 10 to 12 hours. In winter, 3 to 4 are enough.
5 to 7years of life for filter sand
When should the filter sand be replaced?
Every 5 to 7 years, or sooner if the water takes long to clear even with the chemistry right, if the filter pressure climbs quickly after each backwash, or if the sand comes out packed into balls. Glass media lasts longer and backwashes with less water. It is a morning's work and sorted for years.
Frequently asked questions
Everything clear before you decide.
How often does a pool need maintenance?
It depends on the season and on use. In summer, with the pool in use, a weekly visit is the norm. Out of season, fortnightly or monthly is usually enough. At the first visit we tell you what makes sense in your case.
Do I need to be home during the visit?
No. We just need access to the pool and the plant room. How we get in is agreed with you before the first visit, and every visit is logged.
My pool is green. Can it still be saved?
Almost always. It needs a shock treatment, water balancing, extended filtering and floor cleaning. A photo sent on WhatsApp is usually enough for us to give you a realistic idea.
Are chemicals included?
It is set out in the written proposal. Some plans include chemicals in the visit price; in other cases, such as recovering a green pool, it is more transparent to quote them separately.
Do you maintain holiday rentals and residential buildings?
Yes. Those are the cases where regularity matters most: a pool with guests takes far more load than a family pool. The plan is sized for that use.
Where do you work?
We have no fixed area. Tell us where the pool is and we confirm availability and the date of the first visit.
