FAQ – Frequently asked questions about swimming pool renovation in Geneva and Vaud

When is the right time to renovate a swimming pool?

The ideal time to renovate a swimming pool is autumn or winter. This allows us to anticipate the season, avoid spring delays and guarantee that the pool will be ready for use as soon as the weather is fine.
It’s also the best way to take advantage of more controlled schedules and a project completed without seasonal pressure.


How long does pool renovation take?

The duration depends on the type of renovation.
Replacing a liner or technical equipment may take a few days, while a structural renovation (staircase, depth, waterproofing) may take several weeks.
A clear, realistic schedule is drawn up at the time of quotation to avoid any unpleasant surprises.


How much does it cost to renovate a swimming pool?

The budget for pool renovation varies according to the condition of the pool and the desired improvements.
A simple change of liner represents a controlled investment, whereas a more extensive transformation (stairs, depth, equipment) involves more substantial work.
👉 A free, personalized quote is essential to accurately estimate the cost for your pool in Geneva or the canton of Vaud.


Is it possible to renovate a pool without redoing everything?

Yes. In many cases, it’s possible to modernize an existing pool without a complete rebuild:
waterproofing, lining, filtration, stairs, safety or comfort.
The aim is to improve aesthetics, reliability and energy consumption without unnecessary work.


Does a renovation improve the value of your home?

Yes, a renovated, modern and reliable swimming pool is a real real estate asset in French-speaking Switzerland.
It enhances the value of the property, reassures buyers and reinforces the overall image of the property, especially when the work is carried out by a reputable company.


Does renovation reduce energy consumption?

Absolutely. Renovation is often an opportunity to replace old equipment with more efficient, less energy-consuming solutions (filtration, hydraulics, sealing).
The result: a pool that’s easier to maintain, more reliable and less expensive to run.


Do I need permission to renovate a swimming pool in Geneva or Vaud?

This depends on the type of work involved. Some renovations are purely technical, while others may require specific procedures depending on the canton.
Support upstream helps to clarify obligations and avoid administrative bottlenecks.
