Basements in Castellar del Vallès: where the damp comes from
In areas such as Centre, Casc Antic and Eixample and on their outskirts, many terraced and detached houses from the 1980s and 90s have a basement used only as a garage or store. We convert part of it into a gym, den or workshop and, where winters are cold, insulate floor and walls for year-round use.
Where water gets in, in basements in areas such as Els Pedrissos and Can Carner we cut a perimeter channel under the slab leading to a sump with a pump and non-return valve. On the walls we fit a cavity drain membrane and a lining set away from the masonry.
We go down to the basement with you, measure damp and headroom and give you a detailed written quote; a site manager coordinates every stage. We also renovate basements in nearby areas: Sabadell, Terrassa and Sentmenat.

Frequently asked questions
01Basement renovation 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.
02Does the damp need fixing before the basement is fitted out?
Always. First we find out whether the water comes from the ground, a leak or condensation, and apply the right solution. Skip that step and the finishes will end up damaged.
03Can a basement be used as a bedroom?
For habitable use the CTE requires daylight, ventilation and a minimum ceiling height, and local planning must allow it. We check this on the visit; if it isn't possible, we suggest uses such as a gym, wine cellar or play area.
