What bathroom ventilation includes
-
Duct inspection
We check the existing shared shaft or duct and whether it actually draws air.
-
Quiet extractor fan
A low-noise unit with airflow matched to the size of the bathroom.
-
Timer or humidistat
Runs on after the light goes off, or starts by itself when humidity rises.
-
Ducted outside
Ducting to the façade, light well or roof when there is no usable shaft.
-
Electrical connection
A protected supply kept out of the wet zones, in line with the REBT.
-
Air inlet
A gap under the door or a grille so fresh air can actually come in.
Bathrooms in Castellar del Vallès: why the steam and mould stay
In houses and terraced homes in areas such as Centre, Casc Antic and Eixample, upstairs bathrooms are often under the roof. We take the duct up to a vent tile or cowl on the roof, and on the ground floor we find the shortest route to the façade.
For ducting in bathrooms in areas such as Els Pedrissos and Can Carner, we use smooth rigid pipe rather than corrugated flexible hose, on the shortest route through the false ceiling and with a slight fall outwards so condensation does not run back into the fan.
After the visit you receive a detailed written quote setting out the duct route and the type of fan. We also ventilate bathrooms in nearby areas: Sabadell, Terrassa and Sentmenat.

Frequently asked questions
01Bathroom ventilation in Castellar del Vallès: which areas do you cover?
We do this work in Castellar del Vallès, in areas such as Centre, Casc Antic, Eixample, Els Pedrissos, Can Carner, Aire-sol, El Balcó de Sant Llorenç and Can Font, and also nearby: Sabadell, Terrassa and Sentmenat. Before starting we visit the property and prepare a detailed written quote.
02Can the bathroom fan share the kitchen extract duct?
No. Each needs its own duct: sharing one lets cooking fumes and smells into the bathroom, and the CTE (DB HS 3) rules it out.
03Timer or humidity sensor: which is more suitable?
A timer is simple and enough for most bathrooms. A humidistat suits internal or heavily used bathrooms, as it only kicks in when there is steam.
04What if the building's shared shaft does not draw?
We check whether it is blocked or shared with other flats. Sometimes the right fan is enough; if not, we look at a dedicated outlet to the façade or light well.
