Mechanical ventilation in Sant Joan Despí: what we find in homes
In 1960s to 1980s flats in areas such as Centre, La Mossota and Residencial Sant Joan, mould tends to appear after the old windows are swapped for more airtight ones. With continuous extraction in the kitchen and bathrooms and trickle vents in the living spaces, air circulates again without draughts.
In homes in areas such as Pla del Vent, Torreblanca and Les Begudes we start from the CTE DB HS 3 airflow calculation: supply to the living room and bedrooms, extract from the kitchen and bathrooms. We leave undercut doors or transfer grilles so the air path works with everything closed.
We visit the property, measure the rooms and give you a detailed written quote; a site manager coordinates the installation and we leave everything clean. We also install ventilation in nearby areas: Cornellà de Llobregat, Sant Feliu de Llobregat and Esplugues de Llobregat.

Frequently asked questions
01Mechanical ventilation installation in Sant Joan Despí: which areas do you cover?
We do this work in Sant Joan Despí, in areas such as Centre, La Mossota, Residencial Sant Joan, Les Planes, Pla del Vent, Torreblanca and Les Begudes, and also nearby: Cornellà de Llobregat, Sant Feliu de Llobregat and Esplugues de Llobregat. Before starting we visit the property and prepare a detailed written quote.
02What is the difference between single-flow and balanced systems?
A single-flow system extracts air from the kitchen and bathrooms, and fresh air comes in through trickle vents in the windows. A balanced system supplies and extracts through ducts and, with heat recovery, reuses the warmth of the outgoing air.
03Is mechanical ventilation noisy?
Properly sized, it runs at low speed and is barely audible. We place the unit away from the bedrooms and use suitable ducts and silencers.
04Will I still need to open the windows?
Not to renew the air: the system does that continuously. You can open them whenever you like, but you no longer depend on it.
