Penthouses in Castelldefels: terrace, heat and light
Sun and sea breeze take their toll on penthouses in areas such as Centre, El Castell – Poble Vell and Muntanyeta: cracked paving, open joints and windows that let air through. We relay the terrace with non-slip tiles and fit solar-control glass in the most exposed openings.
In areas such as Montmar, Bellamar and Les Botigues penthouses often have sloping or low ceiling sections, which we put to use with made-to-measure wardrobes and shelving. We also check junctions with parapets, chimneys and skylights, where water most often gets in.
We go up to see the penthouse and terrace, give you a detailed written quote with interior and exterior shown separately, and the site manager coordinates each stage. We also work nearby: Gavà, Viladecans and Sitges.

Frequently asked questions
01Penthouse renovation in Castelldefels: which areas do you cover?
We work in Castelldefels in areas such as Centre, El Castell – Poble Vell, Muntanyeta, Vista Alegre, Can Vinader, Can Roca, Els Canyars and Montmar, and also nearby: Gavà, Viladecans and Sitges.
02Why waterproof the terrace before changing its floor?
Because there is usually another home below. If new tiles go down on an old membrane, any leak means lifting everything, so we check the falls, drains and membrane first.
03How can a penthouse be kept cooler?
By combining roof insulation, windows with solar control glass and outdoor shading such as awnings or pergolas. During the visit we see what will make the most difference in your case.
